What 2020 Chevrolet Impala owners say
Electrical system
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. It's being looked into by a senior member at GM for months now, nothing is being done. Radley Chevy in Fredricksburg Virginia hasn't done anything for us either. My family is now having respiratory issues due to the mold issue.
I purchased this vehicle in a CHEVY DEALERSHIP in palatine, IL. [redacted]. 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. …
