The 2020CHEVROLETIMPALA carries 23 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 0 fires, 1 injury, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 IMPALA is unknown or other with 5 filings, followed by electrical system (3) and steering (3). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 57 investigation files overlapping the 2020 IMPALA, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

I purchased this vehicle in a CHEVY DEALERSHIP in palatine, IL. [XXX]. 50k miles a chevy impala around 38k total with taxes and all. A month later I had to pay 200 for a diagnostic at the dealership to check an issue with the steering. They said nothing was wrong with it and it was just the floor mat making contact in the floor. When I returned home, I had the same issue occur AGAIN. I retook it and they wanted another 200 dollars. I complained to the seller of this vehicle, and he agreed to waive these 200 dollars. When it was rechecked, it was found out that it actually had to replace the wheel barring's on the front. It was around a 2,000$ job I have the receipts, and I actually didn't pay for anything at the time due to warranty. I also have been up to date with transmission oil, engine oil, fuel injectors, etc to keep the car running smooth. As of 01/2025 I started having issues with the transmission, the gears were very jumpy and very unsafe to drive. I called the dealership and

The contact's friend owned a 2020 Chevrolet Impala E. The contact stated that while her friend was driving at 25 MPH and approaching a curve, he inadvertently lost control of the vehicle. Â As a result, the vehicle left the roadway, rolled, and came to a complete stop with all four wheels facing upwards after colliding with a tree. Though the vehicle rolled on its back no air bags were deployed. No warning lights were illuminated. The vehicle was towed to a tow yard but had yet to be deemed a total loss by the driver's insurance provider. A police report was filed and injuries were reported. The driver refused medical attention from EMS at the time of the accident but stated that he would seek medical evaluation at a later date as he had hit his head on the driver's side door window as a result of the accident, resulting in visible injuries. The manufacturer was not notified of the failure. The failure mileage was 85,000.
Mileage: 85,000

As I was driving my car in the interstate the car started making noises and began to shake and then it stop driving normally. I did my best to move to the curve and then called a towing truck to get the car. The car transmission stopped working properly. I conducted an analysis on this car in the internet and it has been written that the transmission has a manufacturer's defect. Also, the car dealer did a diagnostics test on the vehicle and proved that the transmission is not responding. The car dealer said the repair is not covered. This car is less than 5 years old. I was driving with an unsafe car. Data indicates that the transmission defects with a transmission fluid leak. I was in a dangerous situation while driving the car in the interstate. There were no warning signs and I believe this can be a dangerous situation for other consumers who may have the same car. The dealer and manufacturer does not want to cover the repair of the transmission since they said there has
I was in a car accident on June 20, 2023. I was stopped in traffic and was hit in the rear and pushed into the vehicle in front of me. The air bags detonated but did not deploy. The steering wheel and both front seat side air bags had some coming but the airbag did not deploy.
While driving the RPMs decrease while the speeding is increasing. At time you can feel the car slow down when pushing the accelerator and then it slightly jumps forward. The car can be going 75mphs and the RPMs will be between 0 and 1. This also causes it to lag.
The contact owns a 2020 Chevrolet Impala. The contact stated that upon parking the vehicle, the "Power Steering - Drive with Care" message appeared on the instrument panel. The contact then attempted to reverse out of the driveway and excessive force was needed to steer the vehicle. The contact restarted that vehicle two hours later and the vehicle resumed normal operation. Neither the dealer nor the manufacturer had been made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 54,000.
Mileage: 54,000
The air conditioner tube was off inside the vehicle and caused massive leaking in the carpets. Causing mold to grow excessively under the floor mats, in the carpets, under the seats, etc. Which as a result led to electrical issues. Itâs being looked into by a senior member at GM for months now, nothing is being done. Radley Chevy in Fredricksburg Virginia hasnât done anything for us either. My family is now having respiratory issues due to the mold issue.
