Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My 2020 Mazda CX-5 was 2 days old and the battery was completely drained and had to be towed to the dealer. I picked it up and they did nothing to the battery. They told me nothing was wrong and they replaced the key fob battery. Two more days after that I parked it in my garage and pushed the button to turn it off. Apparently it did not turn off and come morning, I had significant carbon monoxide poisoning and was hospitalized for 4 nights. My car would not start again and the odd thing was that the battery was drained again and there was still gas in it. …”
