Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
