2019 CHEVROLET MALIBU HYBRID Complaints

Cylinder 7 lost compression due to Cylinder 7 Exhaust AFM cylinder not moving. this is the second time I have had this issue in a little over a year. at the time of failure while driving the vehicle lost all power and would only run 25 - 30 mph causing me to have to veer off on the shoulder. yes it has been reproduced Register Chevrolet has it in the shop now and have found the same issue as before there were no warnings other than a slight backfire and then a severe engine misfire.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was parked in the driveway, and the contact became aware of a puddle on the ground underneath the vehicle. The contact thought that the puddle was coolant, but discovered that the vehicle was leaking oil. The vehicle was taken to the dealer, who determined that the oil cooler line had failed and needed to be replaced. The vehicle was not yet repaired. The contact related the failure to the Customer Satisfaction Program: N192220080 (Engine Oil Cooler Lines Detaching from Crimp – Canada and State of Alaska Only); however, the vehicle was not included. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 118,000.

COMPLETE ENGINE FAILURE AND LOSS OF POWER. While driving, I lost complete power of all systems and truck shut down with no warning lights or alarms at all. Truck is regularly serviced but has always used oil between servicing. Truck had only been driven for 500 miles since last oil service. Upon towing to the repair shop, we were told that the engine was destroyed and we have to have a new engine.

I have experienced a catastrophic engine failure due to the faulty GM DFM lifters and oil pump. I was advised that my vehicle will need a new engine. I know there is Bulletin No.: 24-NA-173 for my vehicle. I have contacted GM, and they advised that there is nothing they can do since the truck is out of warranty. I know they are under investigation for the 6.2 L engine failure issues, and I feel as if this needs to include the 5.3L engines as well. This is very disappointing since I purchased this vehicle new, and have meticulously maintained it. Perhaps the CPA needs to get involved as well.

As I’m driving, the vehicle began shaking and ticking sounds could be heard inside the cabin. A check engine light lit up on the dashboard. The idle was rough and it sounded like metal thrashing in the engine so I turned on my hazards and shut the vehicle off in the middle lane of the street. It didn’t want to turn over a couple times but when I was finally able to get it to start again it made the loud ticking and thrashing sounds. To prevent more damage I put it into neutral and had to push it with the help of bystanders to the closet parking lot putting us and other drivers at risk. I had the vehicle towed to the local Chevy Dealer for a diagnostic and they claim a catastrophic engine failure and recommend complete engine replacement. There were no symptoms of this prior.

Transmission/ignition. Can not lock vehicle and battery will die. When turning the ignition to off, dash message 'shift to park' appears. Must turn ignition on and off repeatedly to get it to go out. Dealership tried tightening a plug but it did not work.

The right bank lifters collapsed this was back in January of 2020. The right bank lifters were replaced haven't had any issues with the lifters since I did however deactivate DFM and auto stop start and I know that is why there hasn't been any more lifter issues. This complaint was way overdue I should have done it years ago.

My 2019 vehicle experienced premature torque converter failure resulting in transmission shuddering, hesitation, and loss of power while driving. The transmission fluid was found to be burnt, and the vehicle requires major transmission repair. These symptoms occurred during normal driving conditions and created a safety concern due to unpredictable vehicle behavior, particularly during acceleration and merging. This issue is widely reported in 2019 vehicles equipped with GM 8-speed transmissions. GM has acknowledged the issue through technical service bulletins but has not issued a recall.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the vehicle experienced reduced power and failed to exceed 25-30 MPH. The contact stated that the failure persisted while driving uphill. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that cylinder #5 wall was damaged and there was oil found on the #5 piston. The dealer determined that the engine had experienced an internal mechanical failure and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 83,260.

Engine oil cooler line blew off of engine while at highway speed. Lost oil and seized engine.
