Our 2014 acura mdx's brake rotors had to be resurfaced after only 13,000 miles. The mechanic at the dealer noted that they have seen many similar cases with the new mdx because it's so heavy. This sounds like a design problem relating to a crucial part of the vehicle. We are not aggressive drivers, nor do we live in an area with lots of stops.

Unintentional acceleration and failure of collision mitigation system 2014 acura mdx advanced. Accident occurred at a strip mall parking lot located 1 mile from my residence where I was grocery shopping. Weather 65 f sunny. Heavy pedestrian and vehicular traffic. I was parked head in diagonally. I placed my right foot on the brake pedal,placed the SUV in reverse,lifted my right foot from the brake pedal, depressed the accelerator pedal and slowly backed out of the parking space,straightening the wheels in the process.I placed my right foot on the brake, shifted to drive, and placed my right foot on the accelerator pedal and without actually depressing the pedal the engin reved uncontrollably and the SUV surged forward 100 ft at increasing speed before colliding in a domino fashion with a row of 6 vehicles pushing one of the vehicles over one of the adjacent vehicles before veering off to the side and traveling an additional 200 feet before coming to a stop.the drivers side chest and knee bags deployed when I impacted with the first vehicle.I do not remember if I attempted to brake.there were no injuries.the damages to my SUV were extensive. My insurer declared it a total loss.I have photos taken at the scene of the accident showing skid marks and the damages to the vehicles before they were moved. My insurer had my vehicle examined by an automotive technician.he concluded that I simultaneously stepped on the brake and accelerator because of the pedal ware pattern. Also the diagnostic port did not show an error code.he did not examine the event data recorder (black box). I do not agree with his conclusions. I believe I did not step on the pedals simultaneously. In retrospect I believe that I accidentally engaged one of the cruise control buttons located on the steering wheel when I was backing up and straightening the wheels.
Our mdx experienced a large amount of brake shimmy going down a hill that almost caused the vehicle to lose control. We were very concerned about the ability of the vehicle to stop. When we took it to the dealer, they said the brakes rotors warped from overheating. Overheating should not occur during normal use, especially when the vehicle is rated for towing up to 5,000 pounds.
I got into a parking space, and pushed the brake but the car jumped onto the sidewalk. I removed my foot from the brake and then the car started speeding up. The car crashed through the window of an empty store. I tried to push the brake even harder but it did not work. The car finally stopped when it hit the wall inside the store. I was in a shock. Luckily, nobody was injured. I found several similar complaints on the internet but could not find a recall for a similar issue. One of the previous claims states: "acura is claiming that no problem can be found with our vehicle." this is an extremely serious safety concern and could result in fatalities. Is there anything else I need to do in order this issue to be investigated seriously?
This is about brake warning system and not about actual brakes.have experienced brake warning light coming on in instrument panel at least 15 times since feb 2014. Activates for no apparent reason. It comes on when there is no traffic in front of me in my lane and no traffic in other lane coming towards me. Has come on when at stop light and start to accelerate. Dealer cannot duplicate when car there overnight. Have talked with acura cust svc and they say they have experienced same in the vehicles they drive from time to time, and have documented some cases from other customers.they seem to indicate sensor is over sensitive and will not replace it. There is a switch to left of steering column where you can turn brake warning system off. Although they state this is not acura's policy and are not telling me to turn it off, it is in reality what they are telling people. If they are going to provide a safety warning system in the car, then it should work. Turning it off due to sensor issues seems like an accident waiting to happen. I have turned the system off and just hope some day I will not regret doing so. Thank you
The car has periodically shown an alert indicating an imminent activation of the automatic braking safety system when nothing has been in front of the car. Today, it did it this morning, and then later in the morning, while driving 30 MPH, the car cut off, making it inoperable and it stopped in a travel lane of a busy road. We were able to re-start it long enough to navigate off the road to a safe location, and it promptly cut off again. After that, it wouldn't run for more than 30 seconds. Every warning imaginable (power steering problem, lane keep assist problem, emission system problem, vehicle stability assist problem, hill start assist problem) was displaying on the information panel in sequential order. We had the vehicle towed to an acura dealership for inspection/repair.
Backing out from parking spot , steering locked up , brakes failed and car kept moving despite maximum application of brakes. Had to turn the power off to stop the car .
Almost one month ago I bought 2014 acura mdx, my first luxury vehicle, coming out of nissan vehicle, thought I would have a enjoy the ride, it only last for one month only with around 1065 miles on the odo-meter. All of sudden while driving, brakes stop responding, and all sort of messages (low brake fluid, engine stability, ldw) on my dashboard. It could have been a life threatening situation, where all of sudden vehicle stop responding to brake. I had to use aux brake to stop it. I would like to report this an issue.
Traveling 65 MPH on a freeway with adaptive cruise control (acc) engaged, vehicle suddenly brakes hard on its own for no apparent reason; dropping 10 MPH in a heartbeat. The vehicle did not produce a collision warning message on the dash. The cars in front on me were well beyond the longest 4 bar range of the acc so it was not detecting and locked onto a car in front of me. There were no cars on either side, no car crossing in front of me and the road was flat with no obstacles. Fortunately, the car behind me was not tailgating as the sudden deceleration could have caused a rear end collision. Sudden deceleration has happened twice during the six weeks I've owned this vehicle. I've also noticed that the acc is inconsistent, often sluggish, in responding to the speed of traffic when it is detecting a car in front of me; creating additional hazard concerns for the driver. *tr..updated 05-27-15 *bf updated 8/28/2017
Tl* the contact owns a 2014 acura mdx. The contact stated while driving approximately 65 MPH with the cruise control activated, the brakes independently engaged. The failure recurred on a separate occasion. The vehicle had not been diagnosed or repaired. The manufacturer was notified of the defect. The approximate failure mileage was 1,030.
Northbound I-95, vero beach, fl exit 147. Prepared to enter deceleration lane at approx. 70 MPH, no pressure on gas pedal, vehicle began to slow. In deceleration lane, attempted to apply brakes to further slow vehicle, brake pedal would not depress. After stomping on brake pedal 4-5 times it finally released and allowed the brakes to function. This was the second event of this type. First occurring 24 dec. 2013.
Our vehicle is an acura mdx 2014 with the advance package. One feature of the package is adaptive cruise control which aims to keep the vehicle moving at a steady rate and at a set distance from any vehicle in front of it. On several occasions, when vehicles in front of ours slows down or a vehicle merges from another lane in front of us (even transiently), instead of gradually braking and speeding up, the acura performs sudden deceleration with hard braking even if the vehicle in front is doing the same speed or going only slightly slower. After the hard braking starts, if the vehicle in front speeds up, our vehicle does not recover and start to accelerate again. I have a pregnant wife who is the main driver of the car and I am concerned that this problem will cause her to be rear-ended.
Brake pedal gets really stiffen up and car won't start unless I depress the brake really really hard. Seems like faulty brake system. This happens when the vehicle has been left sitting for awhile. Happening frequently now.
Tl* the contact owns a 2014 acura mdx. The contact stated that while parked, another vehicle slightly bumped the contact's vehicle and caused it to roll away in reverse and down a hill. The contact's vehicle then crashed into another vehicle. There were no injuries and a police report was not filed. The vehicle was not inspected or repaired. The manufacturer was notified of the failure. The failure mileage was 2,000.
9 dec. 2014 brake pedal would not depress to allow starting of vehicle. After jamming foot against the "frozen" brake pedal multiple times pedal depressed enough to allow vehicle start. No further issues that day. 10 dec. 2014 second occurrence of exact issue as described above. 24 dec. 2014 while driving approx. 20 MPH on an ice covered road, attempted to apply brakes in order to retard vehicle speed while descending slight hill, brake pedal would not depress. After multiple jamming of foot against brake pedal, pedal finally depressed allowing ABS and brake system to function slowing vehicle.
When coming to a sudden stop the brake light will flash on the dashboard accompanied by a beeping sound for approximately 3 seconds. I have brought it into the dealers ship in metairie louisiana and am told that they cannot duplicate the problem. This has occurred approximately 4 times intermittently over the last 3 months. I am concerned because the owners manual states the brake system is failing or the brake fluid is low.
