Left rear outer brake pad was worn down to the backing plate. After repairs were made, it started smoking while driving. We thought it was going to catch on file. I found a Mazda service bulletin - 04-005/16 - regarding a defective brake control module that controls the electronic parking brake. Why wasn't this a safety recall?
2016 Mazda CX-5 brakes complaints
Page 2 of 4: complaints 11 to 40 of 72, newest first, as owners wrote them.
My EPB or Electronic Parking Brake started to Malfunction. It will lock up during parking, and driving and stay locked. It will flash Malfunction light, and the Parking Brake light on the dash will come on, and off. Sometimes If I turn off the vehicle for a while, it will again function. I have not been driving this vehicle, because of the issue I am very scarred my brakes will lock up when it is icy or wet, or slick, and I will injure myself or others Unintentionally. when I first had this issue, I decided to do research, and it seems to be a very common problem across all 2016 model Mazda Cx-5 with EBP. I suspect the EBP module is defective, and I cannot afford to pay the dealer 1500 to replace this part to correct the Safety Hazard Mazda originally created. This should never happen to me or the countless others whom own the 2016 model with EBP. A quick google search will result in countless claims of this same issue with the 2016 model.
Last month, my vehicle suddenly applied the electronic parking brake (EPB) while I was driving. The EPB & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the EPB motor could be heard applying the brake to the rear wheels. When the car was restarted, the EPB would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & EPB motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the EPB switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.
Parked by the curb at the Ft. Lauderdale International Airport. I put the car in Park and left the car idling with the air-conditioning running.as it was 95 degrees and about 100 at around 8:00 AM. There was a shuttle van parked by the curb about 11 feet in front of me. I had to exit my car to talk to the driver in the car behind me. I walked to the car behind me and started talking to the driver. I glanced back at my Mazda CX5 and it started rolling forward. I ran up to the car and got the door open and stepped on the brake. The brakes did not engage. I repeated stepping on the brake several times and the car would not stop. I got in the drivers seat to shift the car into reverse and keep my foot on the brake pedal. The car would not shift into reverse. and by this time the Mazda had pinned to the shuttle van a lady who was trying to unload her luggage. On the sixth attempt to shift into reverse the shifter finally moved into reverse and by standers came to the aid of the lady that had been pinned to the shuttle van. Airport security and the Broward County police took the statements. The lady retrieving her baggage declined medical attention. When I checked to see what the police were reporting they did not acknowledge that I was attempting to stop a runaway vehicle. The report said that I failed to put the car in park and left it in drive. It is not possible to get out of a car that is idling and in gear without the car moving forward or backward before you can even get all the way out of the car. This incident happened about mid July in 2017. Near the end of June this year while in my driveway I left the car idling and in park, exited the car walking to the rear of the car and it dropped into reverse. Got back in the car and shut off the engine. July 2017 the local Mazda dealer inspected the vehicle and could not find as problem. Not unlikely with an intermittent electrical anomaly. There were no prior warning lamps in either incident.
* The Emergency Brake Module failed and it is available for inspection upon request. * The system failed and randomly turned on the parking break while I was actively driving and paused to make a left of a highway exit ramp. The parking break remained on for ~40 mins while I caused a significant disturbance to the traffic and safety of other around me as the exit ramp began to back up while awaiting a tow truck. Since it was the emergency break we were not able to put the car in neutral and push it out of the way. * Yes - Arlington Autocare confirmed the issue and has since replaced the part. * No there were no warning lamps, messages or other symptoms prior to the parts failure. After the issue was identified I searched online and this seems to be an incredibly common issue with the Mazda 2016 CX5. Multiple other reports exist on line about the failure of this park and the rear breaking system. It is very negligent that a recall has not been filed given the pervasiveness of the issue and the seriousness of the safety concern should the part inevitably fail.
The contact owns a 2016 Mazda CX-5. The contact stated that while driving at an undisclosed speed, squeaking noises were heard. The brake warning light was illuminated. The vehicle was taken to an independent mechanic and diagnosed that both the rear brake pads were worn down to 20% and needed replacement. The mechanic informed the contact there was TSB 04-004/19 and 04-005/20 related to the failure and referred the contact to a dealer. The vehicle was taken to the dealer and diagnosed that both the rear brake pads needed to be replaced from normal wear and tear; however, the vehicle was not under warranty. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and informed the contact to schedule an appointment with a dealer for diagnosis. The failure mileage was approximately 22,000.
Ebrake engages on its own when starting up the vehicle. You are unable to turn the ebrake off without restarting the car. The repair shop stated it is a problem with the computer module. A quick search of the internet shows that this is a common issue with this year's make and model. Luckily, the ebrake has not engaged itself yet while driving the vehicle.
I was driving and was approaching a stop sign so I pressed brake to come to a stop. While I was pressing the brake, the car suddenly revved up and lurched forward. I had to switch the car to neutral gear to stop and then back up out of the way of oncoming traffic.
Tl* the contact owns a 2016 mazda cx-5. The contact stated that after starting the vehicle, the vehicle failed to move. The brake and parking brake warning lights were illuminated. The vehicle was towed to an independent mechanic. The contact called jeff wyler eastgate mazda (1117 oh-32, batavia, oh 45103, (513)752-3447) however, the vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The approximate failure mileage was 67,000.
Vehicle has only 29,370 miles driven. The right rear brake lining has undue wear at 3 mm. The left rear brake lining measures 5-6 mm. During routine servicing the mazda technician discovered abnormal brake wear. Mazda dealership recommends replacement of both rear calipers. Mazda corporation is unwilling to help. It appears maxda cx-5 is having problems with their epb and is unwilling to admit it.
The electronic parking brake on my 2016 mazda cx-5 started acting strange a few weeks ago. At first it would not disengage after starting the car, but would do so after a couple of restarts. Then it started engaging slightly while driving, with no indications. Stopping and restarting the engine a few times would usually release it. A couple of days ago this happened and the brake would not disengage after several restarts and I was going to call a tow truck. It disengaged after about 30 minutes. As I understand it mazda knows that the rear caliper is defective (see technical service bulletin r052/16c). This should be a recall item because this is not safe.
Within the last month the electronic parking brake self engaged 3 times when I started my car I noticed the brake light on. I never engage the parking brake when parked in the driveway. I was able to disengage it twice, but the last time it would not disengage. I followed all the steps listed in the car manual, but nothing worked. I had to drive with the electronic parking brake on to the dealership. Upon inspection the service department confirmed it was an internal electronic failure.
Rear brakes are dragging causing heating and uneven wear of the rotors and pads. At 31000 the rear brake pads are completely worn and rotor show heat damage.
My tire pressure indicator light was triggered on when I drove the car for about 40 MPH. I stopped at a parking lot and I noticed the rear right wheel was literally smoking. Later I went to a local shop and I was told the brake was overheated on the rear right side. My local shop replaced the rotor and pads, however, the overheat problem kept showing up on that right rear side. I did some research online and it seems to be a common problem with the parking brake dragging for 2016 cx5. So I stopped using the parking brake and the overheating problem was gone. However, the parking brake is still defective and causes overheat if used.
While driving approx. 40 MPH on a state road, my TPMS warning light went on. At first I thought it was a simple tire pressure issue, but then I began to smell burning. I stopped my car and saw smoke coming from my rear right (passenger side) wheel. I promptly brought the car to a 3rd party mechanic and they informed me the caliper remained engaged and my rotors were overheating. They tried contacting mazda dealerships and 3rd party sources for either new or rebuilt caliper but the part was out of stock and on backorder with no estimated date when it would be replenished. My car is still unrepaired and I cannot drive it as the excessive heating of the rotor could disable my braking ability. This seems to be a common issue with other cx-5 models.
Tl* the contact owns a 2016 mazda cx5. The contact stated that the parking brake inadvertently engaged while driving at various speeds without warning. While driving, the contact suspected that the parking brake was still engaged. The contact exited the vehicle and smelled a burning odor coming from the rear wheels. The contact then took the vehicle to an independent mechanic who also noticed the same failure with the parking brake while driving the vehicle. The vehicle was then repaired by the independent mechanic for the parking brake failure. The manufacturer was not notified of the failure. The failure mileage was 48,784.
Parking brake randomly comes on and won't shut off. I started my car and usually the parking brake comes on but after several attempts it shuts off. Today it will not turn off the parking brake. I have tried several combinations involving to push the start button without foot on brake and release brake with foot on brake before the car fully turn on and when car is partly on to off. After 41 minutes waiting (after spending almost 1 hour messing with it) I turned on the car and it works now. Unreliable transportation!
Parking brake malfunction; dragging of rear wheels especially when turning; sudden seizing of brake while pulling out of parking lot.
Driving the vehicle causes the rear brakes to get hot. This happened multiple times in september (around 40,000 miles), and I took my cx-5 in for service. The technicians did not find anything operating incorrectly, lubricated the brakes, and returned my vehicle. When I got my state safety inspection, I was informed that my rear brakes were passable, but pretty crummy looking because of heat damage. Because we were locked down (due to coronavirus) I waited a bit and just recently had them replaced. Now that my rear brakes have new pads and rotors, the rear brake issue is happening again, specifically on the driver's side this time. After about 15 minutes of highway driving, the vehicle began to shake in the rear and the tire pressure monitor indicated that there was a problem. I took it in to the dealer again, and they told me the rear brakes are operating normally. However, on my drive home (18 miles on the highway), the rear of the vehicle began shaking again, so I knew the issue was not resolved. I checked the temperature of the driver's side rear brake rotor, and it was over 400 degrees (the other rotors were around 150, see page 9 of attached document). I contacted mazda customer service about this issue, and they told me that because the dealer can't detect an issue, there is nothing they can do. Mazda has issued tsbs related to the electronic parking brake for my vehicle, but I believe their diagnostic steps are not sufficient to detect all cases of the issue. Their diagnostic steps are all related to low-speed driving, but my issue only presents itself after driving on the highway for a prolonged period.
My car was parked in a level garage overnight and the next day after driving for about 5 minutes the electronic parking brake (epb) light started flashing on both the dashboard and the epb control lever and the brake light warning light was lit. It seemed to be driving fine, and I never engaged the parking brake so I thought I may have done so accidentally. I pulled over, turned the car off and tried to disengage the parking brake but it just kept flashing. I took it to my garden city mazda dealership to service it for the daytime running lights recall, so I told them about this problem as well. While waiting for the appointment, some days the lights stayed off and some days came on. At the dealership, I paid $140 for a diagnostic and was told that the parking brake module shorted out and needed to be replaced, at a cost of over $900. I asked if there was a chance my brakes would malfunction or if I could drive the car safely and was told the brakes would not be affected, so due to the cost I opted to not have it repaired. This car is less than 5 years old and I should not have to pay for this safety defect. My odometer reads approximately 55,000. Now I have to drive around with a very distracting red parking brake warning light flashing on and off constantly and my brake warning light lit. This distraction is an additional safety concern. I'm not sure if garden city mazda reported this issue to the manufacturer, but apparently mazda is aware of this issue but no safety recall has been made. Why? I feel at the very least, even if no safety recall, that customers should have this issue repaired at no cost as soon as they report it to mazda. Perhaps abc's 7 on your side, pix 11's [xxx] /what a shame, nbc's better get [xxx], or any consumer investigative unit would be interested in featuring this problem - before someone gets killed! Please help! Ty information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
The electric parking brake (epb) has malfunctioned. The car was parked in a level garage overnight, without the parking brake engaged. When the car was turned on the epb light came on and is flashing, as well as the brake light warning. The warning lights remain illuminated on the dash even after multiple restarts. The emergency brake is not engaged and the car seems to drive fine. However I have no emergency brake now, which is obviously a significant safety issue.
Tl* the contact owns a 2016 mazda cx-5. The contact stated that the parking brake on the vehicle was defective and the parking brake indicator remained illuminated. The contact called garlyn shelton mazda (5700 sw h k dodgen loop #363, temple, tx 76504) and was informed that there were no recalls on the vehicle. The manufacturer was also notified and stated that there were no recalls. The vehicle was not diagnosed or repaired. The failure mileage was 33,000. The VIN was unknown.
Sbs inadvertent activation while pulling into a clear parking stall
At 15k miles the driver's side rear brake caliper failed, causing the brake to drag and overheat during a 400 mile holiday roadtrip. By the time the problem was discovered by the elderly owners, the rear pads were worn down to the backing plates and the rotors were heavily scored. There were no warning lights illuminated or other indication alerting the driver to the problem. This is a known issue with the rear calipers and electric parking brake (epb) given the tsbs that mazda has published on the matter as well as the number of complaints online and with the federal safety agency. Mazda replaced the failed driver's side caliper under warranty but declined to cover the damaged pads and rotor caused by their defective assembly even after escalting the issue to corporate. This should be a safety recall but mazda would rather jeopardize the safety of their customer (by not proactively replacing the passenger side caliper) and charge them $500 for a brake job to correct collateral damage caused by their defective parts. We have been long-time loyal customers of mazda but they have acted unethically in this instance and did not fulfill their warranty claim in good faith.
Intermittently, the rear electronic parking brakes do not fully release. This causes the rear brake pads to wear on the rotors. This in turn results in premature brake wear, excessive heat, and a burning smell. This has happened multiple times in all different weather conditions.
42k miles left rear wheel became super hot, took to mechanic, left year caliper was locked up , called mazda they can do nothing car out of warranty, I have seen many of these cars with same issue
My wifes car is just over 3 years old, couple month out of warranty of coarse however the emergency parking brake light for no reason comes on and blinks when it does this it also blink the red light on the dash. It was only doing this at start up however now it seem to do it at random even while driving which is very scary to think your brakes could actually lockup. Called mazda USA, and they said well it must be diagnosed by one of there dealership and even then would not probably consider covering any part of the bill which can run up to $1000.00 for the epb module. This car has been 100% cared for all records barely 21.000 miles, this is the 3rd faulty issue of something breaking on this car-1st- one of those expensive LED lights burned out, 2nd electric seat motor burn out,and now this module and the customer rep states they are not at liberty to discuss if this was in fact a problem and safety issue .please be safe and careful when you purchasing your mazda cx-5
Electric parking break (epb) warning light start blinking after the release of the brake. I lived in a warm tropical weather. In my understanding this function works on cold weather.problem persists intermittently. If vehicle turned off, problem "disappears" but appears again when the break button was released. Weeks later the car started to activate the smart city break alarm when moving in my neighborhood and in a city street with no reason, suddenly, and bringing a safety issue. Also started to make strange noises related to the brake, similar when the brakes or pads get wet and making the car forced to be moved when pushing the accelerator pedal, making the vehicle difficult to move, no matter break is released and turning it slow and vague. An electronic diagnostic report was made and shows the following codes : code c2005 (electric park brake motor gear unit (rh) circuit malfunction code c112a (incorrect electric parking brake motor gear unit position) code c2006 (electric parking brake motor gear unit (lh) circuit malfunction.
On july 25 I slowed down in grocery store parking lot. Slowly approaching parking space and applying the brake to stop car. Then suddenly with no reason the car accelerated, jumped the curb.then car stopped after I hit building fortunately no humans. I was shaken but no bags deployed. I am afraid to drive this car because I am concerned it will do this again and I will be in traffic or near people and I could hurt or kill myself or someone else. There was no warning of any problems. Car is still under warranty to 8/12/2019. The federal safety agency had problem with toyota unintended acceleration in 2010. Please help with unintended acceleration on mazda. People reported this problem before me back to 2015. This is my second complaint . Nobody called me back and called agency been told your employee he cannot give me information I have to write letter and ask. You are government agency and your motto is people saving people. Please do.
I slowed down in grocery store parking lot. Slowly approaching parking space and applying the brake to stop car. Then suddenly with no reason the car accelerated, jumped the curb and hit building. The whole right side was heavy damaged.I had no control. It was unintended acceleration. I moved the car off the grass from building, this time stopped normally. I am afraid to drive this car because I am concerned it will do this again and I could hurt or kill myself or someone else. Car is still under warranty to 8/12/2019.please visit www.carproblemzoo.com/mazda/cx-5/service-brakes-problem and you will see so many cx-5 owners have reported problems related to brakes. Some experienced unintended acceleration twice. This is big safety problem.
