2019 CHEVROLET MALIBU HYBRID Complaints

I am writing to formally express my frustration regarding the ongoing issues with my vehicle. The vehicle continues to overheat, the check engine light repeatedly comes on, and it has cut off unexpectedly. The tire air pressure sensors as well.These issues have persisted despite multiple repair attempts. I initially brought the vehicle to the dealership in December 2024, and again in March 2025 and now the vehicle is having the same issues to date December 2025. On both occasions, the vehicle remained at the dealership for over a month for repairs. Unfortunately, the problem has not been resolved. Each time I inquire, I am given different explanations as to why the issue cannot be fixed, which has been extremely frustrating and concerning. Additionally, I am being charged for services that I do not fully understand or agree with, especially given that the original problem still exists. Due to the lack of resolution, I have also contacted GMC directly to file a formal complaint. At this point, the ongoing delays, lack of clear communication, and unresolved mechanical issues are unacceptable. I requested a clear explanation of all charges, as well as a concrete plan outlining the steps needed to finally fix my vehicle. Please provide the appropriate point of contact and advise on how this issue will be resolved promptly. I expect immediate attention to this matter. Thank you.

Component or system failure: The engine valvetrain (camshaft and lifters) sustained severe internal damage, including camshaft scouring, confirmed during inspection and teardown by an authorized Chevrolet dealership. In addition, the rear differential was found to contain no gear oil when the fill plug was removed during inspection. The vehicle and components are currently at a Chevrolet service center and are available for inspection upon request. Safety risk: The vehicle experienced persistent drivetrain vibration and abnormal operation that worsened over time and ultimately rendered the vehicle non-operable. Internal engine damage and a rear differential without lubrication present a risk of sudden drivetrain failure, loss of propulsion, or loss of vehicle control, particularly at highway speeds. The vehicle is currently unsafe to operate. Problem confirmed: Yes. Engine damage has been confirmed by the dealership during teardown. The absence of gear oil in the rear differential was directly observed during inspection. Inspections by others: Yes. The vehicle has been inspected by an authorized Chevrolet dealership and by third-party inspectors associated with the extended drivetrain warranty administrator. Two inspections have been completed, and a third inspection has been ordered. No repairs have been completed as of this report. Warning lamps or prior symptoms: Beginning around approximately 21,000 miles (2022), the vehicle developed drivetrain vibration. The vehicle was taken to a Chevrolet dealership at that time, but the cause was not identified or corrected. No warning lamps or messages are recalled.

Lifters failed causing complete engine failure gm won’t cover engine replacement but it goes along with the other engine failure lawsuits against gm

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving 45-50 MPH, the oil pressure gauge suddenly dropped to zero(0), and a message stating that the oil pressure was low and to turn off the vehicle was displayed. The contact was able to pull over to the side of the road. Upon inspecting underneath the front end of the vehicle, the contact noticed that oil had sprayed underneath the engine compartment, onto the axle, and the front driver's side tire. The dealer was notified of the failure and referred the contact to the manufacturer for assistance. The manufacturer was notified of the failure and informed the contact that a claim was filed with the dealer. The contact was referred to the NHTSA Hotline for assistance in adding the VIN to GM Customer Satisfaction Program Number: N212326940 (Engine Oil Cooler Lines Detaching from Crimp), which the contact related to the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 106,000.

Unknown, ESC , traction control, service brake. The truck stop and those 2 codes shows and is on but doesn’t it move

While driving at a speed of approximately 55 MPH, the vehicle suddenly displayed a flashing check engine light, ESC error light and stability control warning light on the driver cluster. The vehicle made a loud series of noises and suddenly lost power. The loss of power reduced my ability to control the vehicles acceleration while in traffic creating an immediate traffic hazard. Garage recovered vehicle by tow and found lifter failure, camshaft and cam bearing damage with significant metal shavings throughout engine requiring engine replacement. Repair is estimated at $12,000

On January 28, 2023, my Chevrolet Silverado was involved in a significant multi-impact collision. At the time of the accident, I was a front-seat passenger and my vehicle was fully stopped when it was struck from behind at high speed by a Dodge 2500. The force of the rear impact pushed my truck into the vehicle in front of us, resulting in a secondary front-end collision. This sequence occurred twice. During the collision, the front passenger-side airbag did not deploy, and the front passenger seatbelt failed to lock. As a result, I was thrown violently within the passenger side of the vehicle and struck my head on the dashboard. In contrast, the driver’s seatbelt locked properly, as did the rear seatbelt where my child was seated. Due to the failure of the passenger-side seatbelt to lock, I sustained a severe concussion, a black eye, and other injuries. The vehicle was subsequently inspected by my insurance company. When sheriff’s deputies and state police arrived at the scene, they expressed concern and surprise that the passenger seatbelt did not lock and that no airbags deployed despite the severity of the collision. Shortly after the accident, I contacted GMC regarding these safety concerns. GMC retrieved the vehicle’s Crash Data Recorder (CDR) and conducted an investigation. I was later informed that GMC found no defects or issues with their products. Nearly three years have passed since the accident, and I remain deeply concerned and dissatisfied with GMC’s conclusion. The passenger-side seatbelt did not function as designed, while the driver and rear seatbelts did, and no airbags deployed. I do not believe adequate accountability or explanation was provided regarding the apparent failure of the passenger-side restraint system. Given the force of the impact, I could have been ejected through the windshield.

On 02-07-2025 I had just got on I-95 North In Daytona Beach, FL. While accelerating to merge with heavy fast traffic I reached a speed of Approx 65 MPH. I moved into to middle lane to allow the merging traffic from the LPGA West ramp entrance. At that moment my car was engulfed in smoke the engine stopped running and I had to navigate to the shoulder surrounded by fast moving traffic very dangerous event but I made it. l immediately got out of the truck as I though is was on fire from all the smoke. After several minutes the smoke decreased and there was oil spray all over the underside of the vehicle from front to rear. The Truck had a total of 64000 Miles since new and the diagnosis was from local Chevy Dealer was The Oil Cooler Line came off, the main bearings spun causing the engine to lock up. End result was I needed a complete engine replacement at a cost of $12,689.60. I have had my truck serviced by a GM Dealer so one would think they would check the oil cooler lines when they do the inspections and routine servicing. Long story short the truck was out of warranty by 4000 Miles and I reached out to Gm customer service and after many weeks they agreed to pay back $4441.46 of the $12,689.60 which was something but I guess they really didn't have to because it was out of warranty. I really just told me that they do not stand behind there products. The real kicker is the remanufactured engine that they put back in came with a better warranty than the original now has 36 Month 100000 miles. I consider myself very lucky to not have caused a very fatal accident trying to get off the interstate that day and I am thankful for that. But this event was caused by a $150.00 Oil cooler line. Now I just drive in the right lane because of that experience.

This truck has been very jerky when shifting. Transmission issue plus engine had valves done but still is a problem mostly jerky really bad to the point seat belt is a good thing.

The contact stated that while driving at an undisclosed speed, the transmission failed to shift properly and the vehicle failed to accelerate above 43 MPH, with several unknown warning lights illuminated. The contact stated that the brake pedal became inoperable and required several pumps before the vehicle was able to stop. The contact stated that OnStar Service was contacted and initially provided several error codes on the vehicle. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The dealer was not contacted. The contact later contacted OnStar Service again to obtain the error codes and was informed that no error codes were present, and none were provided. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 43,000.
