2018 Chevrolet Impala Recalls, Ratings & Complaints

Incident: May 1, 2026 · Filed: June 26, 2026

The transmission failed, shifting is no longer smooth. It hesitates and shakes the entire car, and the car slows down to almost a crawl uphill. I understand this is an issue with Chevrolet Impalas. So now I have an $8200 bill for a problem I was never told about, and that GM knew that it existed. So, yes, the issue has been identified, reproduced and confirmed by the dealer. The warning light came on when the issue happened, so it was already too late. The issue began with just over 65,000 miles. So I have a 2018 Impala in almost perfect condition in need of an $8200 before taxes, transmission replacement. I would like some help from the NHTSA, like requiring GM to pay for the repairs. Thank You very much.

Passenger side front seat. When occupied, airbag sensor located inside the seat is malfunctioning. My husbands safety is at risk when he's in the car. He tries moving the seat up, back, etc. Sometimes works and the airbag sensor works. We are fearing that if there were any accident or need, that his life would be in danger if the airbag didn't deploy. This shouldn't be at the consumers expense as this is a safety issue. This has been ongoing for over 6 months.

I was sold a used car w/ undisclosed accidents. Had many issues within first few weeks. Had transmission cooler lines replaced after they burst. Radiator, compressor, condenser, and much more. Then the Airbag light came on. Dealership said connectors were bad. Fixed it. Light came on again.took it in to dealership. They had it for over two weeks. The GM for all the dealerships Told me the vehicle was not unsafe and told me lies. But the service girl confessed she no longer had access to my vehicle or my file and her boss and the Gm had taken over working on it. She then told me they pulled Ford model air bags from my Chevy Impala. Now the light has come on again. I do not feel safe or rust the dealership to fix it properly.

Since vehicle purchase in 2018 there is a shifting problem with the transmission. I have paid for shifter repairs and still the problem exist. While driving the car gets stuck in gear and hard to accelerate. The issue happens at various times without warning. There has been two instances that could have led to potential accidents. Upon spraking with and researching other impala owners, this is a common problem in the 3.6 engine Chevrolet Impalas but nothing has been done. The dealer has a plan to determine but it has always cost $1500+ to the customer.
