2017 Chevrolet Malibu Hybrid

The car completely lost power while being driven on a freeway in Sacramento, California. The car was towed to a Chevrolet dealer in Davis, California and they determined that the car lost power due to a faulty Auxiliary Battery Negative Cable Assembly (Part # 84085823). The Chevrolet dealer cannot find the part because GM has discontinued production of the part. Also, despite extensive internet searches for the part including after-market sites, E-Bay, Amazon, AC Delco, all major auto part supply chains, etcetera, the part has not been found. The car has been at the dealer's facility for ~ 6 weeks with no resolution. The car is a hybrid, has been serviced regularly and properly, has never been in an accident and is very good shape. In other words, if the car is safely repaired, it is still going to be a very useful family vehicle. GM representatives have told the dealer to try to find the part in a local junk yard. The car will likely not be safe if a junkyard part is ultimately used in the repair - the reason the the car is at the dealership is because the car completely died at freeway speed. The cost of the needed part was only ~ $50 (fifty dollars) when it was being produced.

In 2019 I took my vehicle under warranty to the purchasing dealership to fix a "shift to park" reading after the vehicle is parked. It precludes turning off the car. Repeatedly restarting the car and shifting to park and/or jiggling the controller in park usually stopped the reading. The dealer replaced the control shifter, which fixed the problem for many years. This August, the problem started recurring and I have been attempting to make an appointment in the last week, but none of the local dealers say they can repair this for some time. Most cannot even diagnose the problem for a week or two.

In order to turn off the vehicle, the vehicle must be in park. I have experienced several incidences where, despite being in park (shifter is moved all the way forward and the “P” is red on the dash display), the vehicle will not turn off and states to shift to park to turn off. Sometimes I can just return the car to drive and then put it in to park again, but I have had several incidences where I was unable to turn off my vehicle after 10 or more tries to get it in to “park”.

Car voltage stays very high (between 14.8 and 15 volts) for extended periods of time. At which point the windows have fogged up and there is a raw egg smell in the cabin - probably Sulfur. Both the hybrid and the 12v car battery are located in the truck and there are vents that draw air from the cabin to ventilate those batteries. The car voltage will also stay at 12.5 to 12.6 for extended periods of time. During both high and low periods numerous internal systems have failed, including bit not limited to steering assist, anti-locks bakes, Stabilitrack, On star, Hybrid Control Processor and ECM. Car has been brought to the dealer 3 times. First time (early November 2021) it was diagnosed with an hybrid inverter and a software update was installed. Issues continued. As of 12/28/21, Coggin Chevrolet (Jacksonville, FL) has had the car for 2 weeks and can't fix or confirm what is wrong with the car. I have received numerous e-mails from On-star with engine error codes as well as 5 messages saying there is an issue with the Electric Drive Unit in the car. The car has roughly 24K miles on it.

This class action lawsuit was filed in the U.S. District Court for the Eastern District of Michigan by three separate plaintiffs in Wisconsin, Minnesota and Maryland, Car Complaints reports. The suit alleges certain GM vehicles fail to detect when the gear selector has been shifted into Park, blocking the ability for the user to shut the vehicle off. Typically a ‘Shift to Park’ warning message will appear on the driver information center when this happens. The user can jiggle and or move the gear shifter in order to remedy the issue, although this technique does not always work. GM dealer witnessed the problem. MY REPAIR COST AT A GM DEALER WAS $391.11.
