Latest MAZDA5 engine complaints
On several occasions, most of which happened while in motion, my vehicle has stalled out of the blue with no warning. It seems to mostly happen when I'm slowing down or when I'm making a right hand turn and try to accelerate, suddenly there's no power to the engine. I have to put the vehicle into park and restart it. Twice while slowing down for a red light. Twice immediately after making a right handed turn, and once, when entering roundabout, after yielding. This is happened at least five times. The most recent incident occurring in August 2023.
The Mazda 5 was in a minor collision. The vehicle rear-ended another vehicle in stop-and-go traffic. Both vehicles were in motion, approximate speed of the Mazda 5 was 15MPH or less. The front seat airbags deployed. The other vehicle had rear bumper damage but the Mazda 5 immediately had smoke and flames under the hood. Thankfully, all four occupants immediately exited the vehicle to safety. The Mazda 5 quickly burned completely. Police and firefighters came to the scene and everyone agreed that the Mazda 5 fire was not commensurate with the extent of the collision and likely speed of impact. I am concerned there was a major safety defect that caused it to be engulfed in flames.
My check engine light came on. We took it to a mechanic who hooked it up to the computer. It read DTC p2096. When the mechanic looked it up, he noticed that there was a recall issued previously on this specific problem. The description said Target EF feedback system to lean- manual and automatic transmission. When plugging in my VIN number it said it was not affected. But my question is if I'm having the same problem and it affected the same year that my vehicle was made, why is my vehicle not on that recall list?
The tcm failed on the car and it is a very common thing. The design set the module in a location that overheats and malfunctions when connection is lost with mechanisms that warp under heat, the cost to repair at the dealership was extremely expensive
I was driving my Mazda 5 2007 in traffic when suddenly it burst into flames on the passenger side underneath the hood
Random intermittent stalling of the car starting about 100,000 miles. Car suddenly shuts down while driving, most notably while decelerating but sometimes while cruising along. It actually surged and bucked once recently, (Dec 2021 ~ 180,000 miles), while pulling up to a stop. This is causing me to feel increasingly unsafe in this vehicle as it could cause an accident since I have no control whatsoever during these occurrences. Very frightening and risky. Have feared for my life a couple times given the particular timing of the occurrence.

I have gone to multiple mechanics with no help. My vehicle surges or revs any time the ac is on to the point that the vehicle lunges forward even when my foot is on the brake. This occurs in neutral, drive and park. It specifically occurs when I am slowing down, stopping, or coasting at a low speed. It also jerks when in drive but not applying the gas, then revs with no warning. No check engine or other lights are coming on. I have been on several mazda forums and this seems to be a recurring issue wth this vehicle. It has caused me to hit a wall (i was slowing down, coming into a parking space) and my neighbors vehicle as I was waiting to turn right out of our condos.
After repeatedly going to various mechanics to get a diagnosis throughout the years, they were all unsuccessful to find any report through the vehicle's computer. However, my car's engine is constantly revved up even when applying the brakes an slowing down causing it to jerk forward. This occurs suddenly and randomly when I am going at speeds below 20 mph including while on idle. If I neither apply the brakes nor the accelerator, it will still drive forward at 3 mph in rhythmic jerky waves. We took the vehicle to...

the local mazda dealer for a key replacement when we first purchased it, and I believe we reported the problem there first, but after the ridiculous service we got, I never wanted to return there again. This has been an ongoing issue since the beginning.
