What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“I was driving in town through a stoplight when I noticed my brakes stopped working. Also when I had stopped the car still in drive and the car had shut off completely in the middle of the road and was not able to turn back on. The car would keep trying start but none were successful. My car also stated that there was reduced power to the engine and the car would hesitate to gain speed as well. My safety and others were put to risk because my brakes stopped working so I could’ve caused an accident. When we trying to find what was wrong with it through a code reader we had noticed the piece had shattered inside of the engine. No insurance, police or manufacturer has inspected the issue.”

“A software error in 1.5L turbo model disable fuel injectors, preventing the engine from starting or causing a sudden stall while driving. It’s been confirmed to be an previously opened recall that was fixed by previous owner. But, is happening again to me. Yet I’m being told It has been closed and cannot be fixed unless I pay out of pocket. There are warning signs that pop up like reduced speed while I am driving etc. which reduces my speed and is incredibly unsafe.”

“Odometer Fraud. The contact purchased a 2018 Chevrolet Malibu. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 93,000. The contact stated that while attempting to trade the vehicle with the dealer, the dealer declined the trade due to a possible odometer fraud. The dealer discovered from the Carfax report that the mileage was 98,000.”

“I went to put my car in park and it was saying "Shift to Park" on my dashboard even though I was already in park. I know that there was a lawsuit that was won for this very defect but my car is not recalled for this and I feel every Malibu should be especially if almost every Malibu is experiencing the same issue Nationwide. It cannot be a coincidence. Also I have been having issues with a knocking noise on the back of the car when I am driving and I'm being told it's also another common issue with Malibu's known as the Knuckles that need replaced which are not cheap. If these are common issues on every Malibu then every Malibu needs to be recalled for the issue to be fixed not just certain ones. My Malibu has not had one recall but has had the same issues that other Malibu's had with multiple recalls done.”
