What owners report
The contact owns a 2018 Chevrolet Impala. The contact stated that while the A/C was activated during the summer of 2025, the A/C failed to function as intended. The contact stated that hot air was blowing through the vents. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed the vehicle with an EVAP leak. The leak was found on a corner near the evaporative canister. The vehicle was not repaired. The vehicle was then taken to the dealer, where the EVAP leak was confirmed. The vehicle was not repaired due to the cost. The vehicle was taken to a specialty shop for the repair. The manufacturer was made aware of the failure and offered to pay a nominal part of the repair. The contact declined the assistance. The failure mileage was approximately 60,000.
I noticed lately my car has trouble starting, especially after I get gas. Anywhere I take it, no one knows what it is. Literally someone said that I'm not holding the brake down when I'm starting it. I KNOW HOW TO START MY VEHICLE! It doesn't want to start and sounds like a broke down Saturn when I start it. It takes like 20-30 seconds to start. ALSO that AC went out, I paid $700 AT Chevy, and then the AC went out again a few months later, again no one knows why. WTF!

For approximately 2 months, my 2016 Impala LTZ, would display a message on the small screen in front of the driver in the dash, stating for the driver to, "press ignition button again to turn vehicle off." The worst part about it was this would happen very randomly whether I would be driving in city traffic, or be sitting in a parking lot at a local store. I took it to my local Chevrolet dealership. Five different times, because they were not able to get the occurrence to duplicate for them. They replaced the ignition, as well as other suspected parts with no resolution. Resolution. Ended up costing me over $1,200. That was the first time I took it in for this issue. The other four times didn't cost me anything because they hadn't fixed the issue. …
On Fb 08 2022, at app 5:30 in the evening my 2016 Impala had a non-driver directed surge of speed. As I was slowing down to enter a driveway, the vehicle surged forward powerfully. I was able to press the brakes forcefully engaging the antilock mechanism. The vehicle shook as I continued to apply breaking force. It came to stop barely missing another vehicle parked in the driveway. I have no explanation for this dangerous episode. I had not used any type of automatic speed control. The car is serviced by authorized dealership: Hampton Chevrolet in Hampton VA. I was in the car with two of my grandaughters when the incident occurred. I was able to drive the car back without any problem, but I'm scared to drive it.
I was involved in a collision while driving my 2015 Chevrolet Impala police vehicle. The front of the vehicle struck the right side of a vehicle that turned left in front of me. The patrol car caught fire during the collision and was only put out when the fire department cut the battery cables. The apparent issue is that after a major collision the fuel pump did not turn off which caused fuel to be added to the fire......updated 02/10/16
While I was driving down an interstate in heavy traffic (rush hour) getting ready to merge onto another interstate the vehicle lunged violently jolted and lost power. At that time I was driving (cruise control off) at 60mph, the display lights on the dashboard came on stated: stability control, traction control,check engine came light on, and vehicle rapidly slowing. I was able to move to the right lane and access and exit ramp. Once that happened you can't get vehicle to move when pressing on the gas pedal. I put it in park, turned off the vehicle. I waited for a few minutes then turned on the car. The check engine light remained on. Vehicle has done this a few other times however; no codes come back when diagnosed as the check engine light turns itself off. This seems to be a major issue however; GM doesn't want to accept responsibility and fix their issue to make their vehicles safe. …
