The issue started happening [XXX]. I was driving home and the car went into limp mode. Several errors came on the heads up display and on the dashboard. At first I could not go faster than 31mph, then it dropped down to 17mph, then to 7mph by the time I got home. 1.When accelerating from a stop light, car goes into limp mode and won-??t accelerate almost stalling in the road. You must pull over, turn off the car and wait 5 minutes so error clears so you can drive again. 2.Car goes into Limp mode when going up a hill 3.Between 46-48 mph, car hesitates when accelerating 4.Between 56-60 mph, car hesitates when accelerating 5.Error Codes received per Lake Car Care: P2299, C1001, B1303 I brought the car to Lake Car Care and they replaced the spark plugs and coils as the codes said it was a misfire on Cylinder 1 & 2. This cost me $ $947.57. This did not fix the problem. The mechanic Todd took the car for a ride and it went into limp mode for him also. He could not figure the issue out after having the car for a couple weeks so suggested I take it to Mazda in Clermont. Mazda has had the car twice for over 2 months now and cannot figure it out. They replaced the ABS Module for $ 1284 which did not fix the problem. Replaced the injectors for $ 1426 which didn't fix the problem. They did a fuel compression test which came back fine and cleaned the catalytic converter which they said was clogged and this didn't fix the issue either. It is unsafe to drive this vehicle on the road as it does not accelerate so it is putting myself and others at risk. Mazda corporate has been called and case manager has been assigned but has been NO HELP to me at all. Photos are attached of all error messages, text messages with Mazda, repair receipts, etc. August 9th, Mazda told me they are at a loss and don't know what else to do, I haven't heard from them since. Please help. I am at a loss and don't know what my options are. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Cruise control suddenly ceased operating and I believe that is disabling the automatic collision avoidance system.

UNKNOWN My vehicle stalls while I-??m driving. My RPM tends to stay at one number when this happens. I was nearly struck by a vehicle while trying to merge onto the highway. This is very dangerous. There-??s also I light that comes on my dashboard that seems to be indicating an accident or something of that sort.

Will not accelerate at times no matter how far you press down on gas pedal and will stall right after. I will pull over shut off vehicle and restart. This sometimes corrects the problem right away. Other times it lasts longer. System malfunction light randomly comes on.

While parking at a very slow speed, the Mazda suddenly and on its own accelerated and ran into a fixed object. The vehicle was off the road in a grassy parking area when it happened...

On May 9, 2020, our Mazda CX5 lost thrust, stalled and came to a complete stop while driving on a highway going 55 mph on a straight 3 lane road. This occurred despite the PCM programming was re-calibrated due to a manufacturer recall in September 2019 (NHTSA recall no. 19V497000). The car is towed to a Mazda service centre and is awaiting diagnosis.

Made a slow right turn into a parking place to pick up my dogs at the groomer, when I applied brakes to stop, the car accelerated lurching forward. I then took my foot off the brake and reapplied instead of slowing down the car sped up and was only stopped when I hit a brick building. I had two dash warnings "front camera sensor system malfunction" and "forward smart city bread support malfunction" I am not certain how fast the car was moving when I hit the building but the entire front of the car is significantly damaged. Further the air bags did not deploy. I have photos of both the collision damage and the warning lights. The dealership requested they run diagnostics and found nothing wrong claiming the accident was my fault as I must have put my foot on both the brake and gas at the same time. I am an experienced driver and this was not the case. The also stated the warning lights were a result of the accident not the cause. I am only grateful I was not pulling into a space closer to the door as I would have gone through a plate glass window and most likely would have cause a serious injury to anyone standing in the lobby.

Nist campaign 19V497modifications were made. The vehicle now decelerates up to 6 mph on hill ingress; on egress the vehicle goes at least 3 mph over setting. When passing cars on a hill, the car slows down when relying on cruise control to resume driving, thus causing us to step on the gas to hold a safe distance from the passed car. We have lost at least 3 mpg fuel efficiency. We have returned to the dealer and they indicated that the vehicle is operating as expected. This fix is a safety concern.

The contact owns a 2018 Mazda Cx-5. while pulling into a parking space at 5 mph, the vehicle accelerated on its own while the brake pedal was depressed. As a result, the vehicle drove over a median and crashed into another vehicle. The air bags did not deploy. There were no injuries and a police report was filed. The vehicle was towed to schwartz Mazda (585 shrewsbury ave, shrewsbury, NJ 07702, (732) 945-5100) to be diagnosed, but the cause of the failure was undetermined. The vehicle was then taken to an independent mechanic for diagnostic testing and repairs. The manufacturer was notified and did not assist. The failure mileage was 650.

  • 6,950 miles
On January 10, 2019, I slowed down in my local grocery store parking lot, going about 10 miles and hour, and was coasting into a parking space at about 5 mph. It was about 1:15 pm on a sunny, clear day. I was applying the brake to stop the car as I pulled into the spot yet I was going slow and coasting straight into the spot. Suddenly, the car sped up, the brakes had no response, and the car accelerated hitting 3 parked cars near the parking space. I did not have my foot on the accelerator, I had my foot on the brake... but more than anything, I had no control, it was unintended acceleration. Then the car stopped after I hit three vehicles and fortunately no humans. I was shaken, but no bags deployed. I have approximately 6950 miles on this car. I have been the only owner. 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 problem. I don't want to update my documents on the internet but will submit once I have an NHTSA employee reach out to me. My records include a filed police report, a report with Mazda corporate (as of today) and pictures of the vehicles which are available upon request.
