2018 Mazda CX-5: jerking or lurching

Filed May 12, 2026 · Brakes · CA · crash

Unintended acceleration incident. I entered the parking lot of a business where the Salvation Army is located to drop off a donation. The parking spaces were on the left side. As I pulled into a parking space and was in the process of parking, the vehicle suddenly lurched/accelerated forward unexpectedly and struck the concrete wall of the building. The airbags did not deploy despite the frontal impact. No one was seriously injured, but my husband, daughter, and I experienced soreness the following day from the impact. Thankfully, I had chosen a parking space in front of a concrete wall rather than the glass storefront windows, which could have resulted in far more serious injuries or damage. I contacted my insurance company, and the vehicle has since been repaired.

Car has since been repaired by Mazda, but pictures are available from the incident. -Car was unsafe to drive due to leaking oil all over road (Environmental risks and hazard to others), black smoke and burning smell circulated into cabin via AC (health risks to passengers).

Was driving at low speed and out of nowhere the warning lights came on , smart city , abs, among others. It's caused by this vehicles front facing camera and or front radar emblem malfunctioning causing the vehicle to slow down , low power , and steering wheel jerking making mechanical sounds. There's a tsb as well.

Brakes failed when at complete stop car lurched forward about 2 car lengths

While stopped at a pharmacy pick up window, I engaged the auto hold. I took my foot off the break and about 3 seconds later my car lurched forward about a whole car length. There was nothing in front of me, but had there been I would have hit it.

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.

I just use my car around town...putting less than 10,000 mi a year on the car. This problem has happened several times. I mentioned the problem to the dealership when I bring the car in for service, & they return the car saying they didn't find a problem??? Problem: I'll be driving along, around town...usually going around 20-30 MPH, on lamar blvd. I have to slow down because the car in front of me decides to turn into heb parking lot. What I think happens...my foot goes to the floor...no braking! No braking, & then the car jerks & seizes. I can't tell you how many times I almost got hit in the back!!! Please help me figure out what the problem is... I just lost my husband & the last thing I need is an accident. The date you required below was the last time the incident happened.

The vehicle wants to keep going when the brakes are applied. When at a stop light, you must keep you foot firmly on the brake as the car wants to lurch forward. When you slow down while driving, the car acts like the turbo is kicking in and wants to lurch forward. Very dangerous. I thought it was the engine, but someone told me it is the transmission.

On the third day after leasing this brand new car, I was driving at approximately 20 MPH, on a normal city street and slowly pressed my foot on the brake as I approached a red light on a standard city street. No cars were in front of me, thankfully, because as I pressed the brake the car accelerated instead of stopping; the engine and parking warning lights (and several other random lights) illuminated and flashed; and at least three text malfunction warnings appeared in the control panel including scbs malfunction. The car was jerking and accelerating forward throughout even though my foot was on the brake. Mazda's tech said that all the malfunctions I observed appeared on the computer readout, but because they could not replicate the problem after a computer reset, they told me that the car "is running as the manufacturer intended." this is terrifying.
