2017 Mazda CX-5 Vehicle speed control Problems

“The car stalled while in motion on the highway with 56 miles left in the gas tank. This caused a very dangerous situation due to the fact that I could not accelerate at all, as the traffic was speeding past. I had to coast through traffic to the safety of the shoulder of the road. Once the vehicle came to a stop, it wouldn't restart and it seemed as if it never actually stopped trying to restart. I noticed a few things during this situation. 1. The check engine light came on 2. All the dash board lights appeared to come on 3. …”

“My vehicle was on a city street behind a car which was at a stop sign. I stepped on the brake pedal, but my cx5 did not slow to a stop, but kept going at a steady speed toward the car ahead. My car suddenly stopped about 5 feet from the car ahead. My foot was on the brake pedal the whole time. This happened twice. Another time I was stopped behind a car making a left turn . With my foot n the brake pedal my vehicle moved about 3 or 4 feet and stopped before hitting the car in front.”

“Yesterday my wife tried to stop our cx5 in our driveway but it kept a slow glide for a few yards thus crashing into our garage door. Shifting into park a 2nd time (1st time didn't work) and pounding the brake pedal finally stopped the vehicle after pushing in the garage door a few feet. Engine remained in low idle (no acceleration) and brake feedback was normal (not mushy) the whole time. This is 2nd occurrence. First occurrence was about 6 months ago as the cx5 glided part way into an intersection. All symptoms listed above were exactly the same.”

These features malfunctions in las vegas during hot weather. Mazda knows about the problem and has no fix. We bought a Mazda CX-5 on june 9, 2017. While driving on the freeway on july 21, 2017 the car quit working properly and we had three warning messages come up on the dashboard: 1.smart city brake support malfunction 2.smart brake system malfunction 3. Forward camera malfunction. …”

“My 2017 Mazda CX-5 has experienced a recurring condition more than six times involving sudden jerking, rapid deceleration, and loss of normal accelerator response during extended highway driving, often while cruise control is engaged. On multiple occasions the engine has also shut down. On 09/11/2026, while traveling south on I-35 at approximately 80 mph with cruise control engaged, the vehicle suddenly began jerking violently and rapidly losing speed. Normal accelerator response was lost and a vehicle behind me nearly struck my vehicle. …”
