While driving my mazda car, it suddenly started bucking and check engine light came on. Car was towed to the dealership. Per mazda mechanic, water pump malfunctioned forcing coolant into the engine. Feel this poses a significant safety issue as there was very little warning posing risk of accident, engine overheating and potential fire. This appears to be a common issue as multiple other posts reported
2012 Mazda CX-9 engine complaints
Page 2 of 2: complaints 11 to 26 of 26, newest first, as owners wrote them.
Fuel pump failure causing engine failure and to die in motion on a rural highway. Vehicle had to be pushed off the road.
The transfer case is leaking and going to go completely out on my 2012 mazda cx-9, I noticed the same gear shifting problem in my 2004 mazda 6 wagon. The car feels like driving a stick, it jolts when shifting to drive and while moving it feels like it is shifting early. This is a known problem with mazda but a recall is yet to surface for this issue.
While driving my vehicle on the highway my car would not accelerate when I pressed on the gas. My RPM's went up to 4 and would drop down when I let off the gas. Within minutes my steering wheel locked up and the car basically shut down. I had to try and drift to the shoulder in high speed traffic. When I got to the shoulder the car started smoking. I had the car towed to mazda dealership. They told me my water pump went and leaked fluid throughout the engine, resulting in me needing a new $8,000 engine. They told me that mazda designed the cx9 where the water pump is in the engine block behind the timing belt and it is not something they can easily inspect when I bring my car in for service. So when a water pump goes on these mazda cx-9's it results in the consumer needing a whole new engine. They also stated that there are no indicators that will notify you if there is a problem with the water pump to avoid this from happening. The safety issue is that my car was on the highway at the time this occurred with vehicles going at high speeds. My car basically slowed down significantly and eventually stopped and I could not turn the steering wheel to better assist me getting out of the way of the high speed traffic.
The mazda cx 9 cuts off without warning at traffic lights. It also has cut off at low speed turns. It restart some times. Sometime it will not for a few minutes. Been left in the middle lane of us 27 south of sebring florida at a traffic light stalled. The RPM fluxuates at times and the vehicle surges. Dangerous situation when in the center lane and it just cuts off with no warning. No engine check light or warning prior to cutting off.
Multiple trips to the dealership and an independent mechanic and the check engine light (cel) comes on with a diagnosis of evaporating system / loose gas cap. Multiple diagnostics fees, a gas tank pressure test and 3 gas caps later and the problem has not been fixed. I noticed a few online forums with several others complaining of the same issue across a wide rage of years and mazda models. There is a design problem with mazada evaporating, fuel and emissions systems. The dealer cannot identify the problem. Beyond replacing the gas cap and collecting a diagnostic fee.
Purchased the vehicle new from davis moore mazda- wichita, ks. For the past 4 years we have experienced multiple engine stalls as well as complete engine stopping while driving, city, highway, turning etc. Have had the car into their service dept. Many times and they keep saying it is fine ( the last time they said it might be caused by having 8 oz too much engine oil in it). We have less than 12,000 miles on it to date because we are afraid to drive it. I believe this is a very real safety issue. We have all the paperwork for each service dept. Visit. Last two visits we were treated like we were making this stuff up. This has been happening every year since purchasing.
Tl* the contact owns a 2012 mazda cx-9. While driving 20 MPH, there was a loud metal to metal noise coming from the rear of the vehicle. In addition, the gears failed to shift correctly and the oil and engine indicators illuminated. The dealer diagnosed that the brakes needed to be changed. The brakes were replaced, but the failure recurred and worsened. The contact also smelled fuel coming from the vehicle and the vehicle had trouble accelerating. The manufacturer was notified. The failure mileage was 33,000.
Tl* the contact owns a 2012 mazda cx-9. The contact stated that while traveling 15 MPH, the vehicle exhibited difficulty in decelerating. The contact had to pump the break pedal extremely hard in order to slow the vehicle. There was a hissing noise that sounded throughout the vehicle. The vehicle did not decelerate until approaching an incline. The contact was able to stop at a local mechanic shop where the mechanic diagnosed the that the brake vacuum booster needed to be replaced. The vehicle was repaired. The failure mileage was 55,000.
I have an issue with the brake pedal making a hissing sound when depressed, it fills soft and extremely hard, which makes it difficult to stop. If I release the brake pedal the engine revs up and down at least three times making the car hesitate with engine clunking and a feeling like someone hitting you from behind. It happens very sudden and unsafe manner. I had two occasions when a had to press extremely hard on the brake to stop the car. I think that there is a serious mechanical defect with the brake system and should be immediately addressed by mazda. I had researched on line and there are number of mazda cx9 owners with similar complain. Please feel free to contact me for further assistance with this matter.. Sincerely.

I am unsure of the first date of occurrence, but the following have been happening since I purchased this vehicle new with 12 miles on it. And the dealer can't find anything wrong with it. 1. The AC always comes on. Even when it's below zero outside. 2. It fails to go when pushing on the accelerator frequently, and especially in reverse, from a stopped position, until you really push hard on the accelerator causing it jump. 3. Last friday 2/21/2014 as I was on a ramp moving from one interstate to another, the engine continued to rev up even after I let off the gas, and pushed the brake. This is not the first occurrence of this, it's actually happened at least 10-12 times. It was definitely the most scary, as I thought I was going over the side of the ramp or into the semi in front of me for a minute or so. 4. The brakes squeak loudly when it's cold. 5. The brakes are either really sensitive, or you have to stomp them to get them to work, so since you don't know which it's going to be you're likely to jerk yourself and your passengers around a lot. 6. The vehicle pulls to one side or the other, which would seem to indicate that an alignment is needed, however, it can't pick which side it's going to gravitate towards which leads me to believe it's something in the steering.
Tl* the contact owns a 2012 mazda cx-9. The contact stated that while driving approximately 45 MPH, the vehicle stalled unexpectedly. The vehicle not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 35,000.
I have a mazda 2012 that spontaneously stalls while decelerating. It also stalls predictably on an incline. Mazda corporation has stated "the stalling on an incline is a characteristic of all cx-9 models" and are not willing to fix it. They have informed me that stalling while decelerating in my car has not been able to be recreated by their tech so they are doing nothing about it. I have been in two near miss accidents. The car loses power steering and braking and the driver has little to no control when it stalls. Please watch this video of a brand new (loaner from the dealer while they looked at my 2012 cx-9) 2013 cx-9 (125 miles on it). This is the "characteristic" I am referring to, please advise future buyers of this very unsafe "characteristic". When it stalls in my driveway, I cannot brake "sharply" or effectively enough to stop the car from drifting into the road. Http://youtu.be/pbzhvieihkc.
Incident -1 traveling about 45 MPH decelerating to make a right turn, the car stalls out leaving me with no control of steering and little ability to brake. Incident 2- making right turn (decelerating) car stalls out leaving me with no steering and little braking control. Incident 3- pulled up into driveway on slope. Put the car in reverse to back out, car stalled out leaving me with very little ability to brake.
Tl* the contact owns a 2012 mazda cx-9. The contact stated that the vehicle would consume excessive oil without warning. The vehicle was taken to a dealer where the failure was unable to be replicated. The contact stated that the technician mentioned that the consumption of oil was unusual and could cause the engine to fail. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 900 and the current mileage was 42,000.
I had an incident yesterday resulting in a minor collision. My accelerator stuck, my engine kept revving, and I could not stop. I kept applying the brakes but it felt as if everything locked up. I rearended the person in front of me no damage to their car and only minor to mine. I am now afraid to drive the vehicle. My husband contacted the dealership and they are waiting to hear back from mazda corporate.
