2019 CHEVROLET MALIBU HYBRID Complaints

On August 1, 2024 I had a knocking in engine Drove 3 miles to Dealer and was told engine needed rebuilt. 88643 miles cost estimate $ 7000. I refused came back GM would pay half I paid 3937.49 On 8/13/2024 I had no choice, I needed it fixed! They should have told me about engine problems and sold me insurance when GM Warranty was expiring I want reimbursed!!

I was driving to work in the morning and started to accelerate to the speed limit of 45, and at about 35mph my truck completely shut off. I tried to push the start button while coasting with no avail. I pulled to the shoulder and tried to start it and it would slowly crank similar to a dead battery. I towed it home, then tried to start it later in the day and it started no issues, however ever since then there is a knocking noise from the lower end. I have had it parked for a few weeks and Monday December 15th it will go in to a Chevy dealership for a diagnostic appointment. No there was no lights or warnings related to this, and this did put my life in danger being stranded on the shoulder of a road with limited room to pull off too early in the morning dark out.

While driving the engine suffered a catastrophic failure and died. Fortunately I was already coming to a stop when it happened. Had I been traveling at speed I would have been seriously injured or killed along with any other vehicles I may have crashed into. The Chevrolet dealership where vehicle was purchased new confirmed it was a catastrophic failure of the GM L87 engine which has knowingly been fraught with these failures. They cannot confirm the exact nature of the failure without dismantling the entire engine at my cost which I have not decided upon doing yet as it will be very expensive. As far as symptoms or warnings I heard a sound from the engine compartment immediately before the engine died.

The vehicle was shifting hard and eratically on the highway. All dashboard lights came on including the ESC failure warning. A misfire in cylinder 2 occurred without any warning lights causing the vehicle engine to stop running on a highway. The mechanic repair shop did a disgnostic evaluation and reported a catastrophic engine failure from cylinder 2. The engine does not run and requires full replacement. The vehicle has only 80,000 miles.

In March of 2025, my engine started knocking and had low power. I took it to a local mechanic and he said it was the classic 6.2L rod knock. I took it to the dealer in Decorah Iowa and they agreed that it was the rod knock from the recall. Since it was not covered under the recall, I had to pay almost $10,000 to have it replaced. It took over 4 months to get an engine and then it was finally replaced.

Engine oil cooler lines leaking crimps. Crimps could completely fail losing engine oil and causing an accident. Dealer has confirmed the issue at last visit.

Purchased Truck in 2019 - 2 weeks after purchase the truck gave a Code and started to stall while in motion. We took into dealership and they did a complete review. They discovered and documented the following: Removed transmission fluid pump and disassembled to inspect- found a large piece of manufacturing metal flashing - that got stuck in valve bore preventing full movement etc. we kept up on all of our maintenance oil changes. We had the transmission flushed just near the end of the warranty as they recommended it. Shortly after, we started experiencing the same issue. Per the dealership, no recalls for this. The power would completely shut down while driving. Took to dealerships , now telling us we need new transmission $12,000 and is the reason for the power shutting down. They are saying GM will offer us $2,000. We feel this is all due to the flushing and maybe having particles from the flushing,

My 2019 Chevrolet Silverado 1500 with the 5.3L engine developed a severe tick, misfire, and rough idle at only 93,000 miles. This was diagnosed as a collapsed AFM lifter on Cylinder 2. GM 5.3L AFM lifter failure is extremely common in these trucks and causes sudden loss of power, misfires, and unsafe driving conditions. This is a known widespread defect, yet GM has not issued a recall. The failure happened without warning and required major engine disassembly. This should be investigated as a safety and reliability issue.

The 8-speed transmission has been a problem from day 1 of owning this truck. It has a bad vibration, slips into gear and hard shifts. I have maintained this truck to the fullest and have done all service to the fluids as requested by the manufacturer. I have never pulled a trailer, and I want The NTHSA to make all Chevrolet products that have this 8-speed transmission recalled. GM should make this right. These vehicles aren't cheap.

The transmission consistently fails to shift properly, hanging between Drive and Overdrive. The dealership initially diagnosed the issue as a faulty torque converter & lines, then a tow/haul switch, and replaced it; however, the failure persists. The transmission now requires full replacement. I believe this is a known manufacturing defect present prior to the vehicle's release. Additionally, the lifetime powertrain warranty originally attached to the vehicle has been removed from GM's records. This hesitation causes unpredictable acceleration and loss of power, creating a significant safety hazard when merging onto highways or navigating heavy traffic. It is available for inspection upon request.
