The contact owns a 2016 Chevrolet Malibu. The contact stated that while driving at 61 MPH, the vehicle unexpectedly began idling roughly. The contact stated that a loud noise was heard coming from the vehicle, and the cooling fan cycled on and off. The vehicle was taken to a service center, where it was found overheating. The cause of the failure could not be determined initially; however, the mechanic stated the failure was a known issue requiring a special diagnostic tool. Diagnosis revealed three piston rings leaking at 5 percent and the fourth piston ring leaking at 95 percent. The contact was informed that the piston rings could potentially be repaired if the necessary remedy parts were available for the model year. The failure mileage was approximately 66,000.

2016 Chevrolet Malibu Hybrid LT 1.8L - current mileage 147,059 miles The factory exhaust heat exchanger failed internally, leaking engine coolant into the exhaust system. This caused check engine codes P0401 / P26BE, loss of cabin heat, coolant loss, and exhaust fumes entering cabin. GM has released 4 revisions of this part and all fail the same way, indicating known defective design. The part is currently on indefinite national backorder with no ETA from GM (Order #343585 from GMPartsNow on 08/22/2025 held without ship date). Dealers quote $1,587 and cannot obtain part either. This is a safety and emissions defect: coolant loss risks engine overheating, exhaust leak risks carbon monoxide in cabin, and coolant contaminates catalytic converter. GM discontinued Malibu Hybrid in 2019 without proper fix. This should be recalled. They produced a car, we bought it and now they don’t have the overpriced parts in stock to fix my car and when the parts is backordered, I keep driving it because i can’t work without my car which I very much need, the hybrid battery gets overheated, then they sell battery too and other damages too which will cost thousands to fix. This is a scam!

My car started overheating on my way home. I pulled over to find that there is a hole in my lower radiator hose, which was caused by the lower radiator hose being rubbed against the belt that is turned by the water pump. I had my wife and child bring me coolant on the side of the road where I was broken down. I eventually was able to get my car to my brothers but it required multiple stops and refilling of coolant. Once we got the car jacked up and the lower radiator hose replaced, we found the bottom of the radiator is loose and is pushing the lower radiator hose against the belt that rubbed the hole into the lower radiator hose. I then had my car towed to Dan Cummins in Georgetown Kentucky, located at 1470 Cherry Blossom Way, Georgetown, KY 40324. The mechanic drove my car that I had towed to the shop which damaged the new radiator hose that I had just put on the car. Dan Cummins of Georgetown Kentucky, who is an authorized Chevrolet Dealership, was informed (by me) that some 2016 Chevy Malibu's have been recalled because of a faulty lower radiator mount causing the lower radiator hose to push against the belt which causes the lower radiator hose to get a hole and leak. Dan Cummins suggested that I report my issue because my VIN is not covered by the recall. Authorized Chevy dealer Dan Cummins also suggested that I take my car elsewhere to be repaired while refusing to cover the damage they caused to the brand new lower radiator hose that I had purchased and put on the car. I would like for my Chevy Malibu with VIN [XXX] added to the recall so that I can have my Chevy Malibu repaired by an authorized Chevy dealership at no cost to me for something I did not do or cause.

My 2016 Malibu has a severe EBCM-related safety defect causing all four brakes to drag and overheat (reaching 240°F), leading to unstable handling. This condition mirrors the 2016 Malibu EBCM recall (GM Recall 39440). I sought help from GM. A GM-certified dealer-Monken in Centralia, IL performed a “diagnostic scan” which documented the core hydraulic failure: a constant, uncommanded 6.839 psi residual brake line pressure when the pedal was released. (A healthy system should be near 0 psi) This 6.839 psi is actively forcing the brakes to drag. The dealer ignored their own scientific data and submitted a fraudulent diagnosis of ("rust buildup") to GM, which GM used to deny the claim based on mileage. “Rust buildup” doesn’t create hydraulic pressure. GM is aware of this specific, documented, quantifiable safety defect (the 6.839 psi pressure) and is refusing to investigate it further. I stressed to GM that the vehicle wasn’t safe to drive and that I have a small child who has to ride in the car with me. GM dismissed my concerns by stating the dealership won’t release my car unless its safe to drive. I then had to drive the car 22 miles back home with all 4 brakes dragging. I requested the full diagnostic scan report (that the mechanic confirmed he could provide me with when I dropped my car off there) numerous times and never did I get one. I informed them that I would be filing a complaint hadn’t I received it by a certain time. The new kid in service then did send me screenshots of a generic OBDII scanner where I saw the 6.839 psi. I knew what the issue was prior to taking my car to Monken. I had an independent scan done prior. I only took the car there to comply with GM’s protocol to be eligible for assistance. I am requesting the federal safety agency investigate GM for failure to address a documented hydraulic control safety defect that causes brake dragging and overheating, which is non-compliant with safety standards. I can give further info Please call me for further details.

The vehicle has experienced ongoing engine performance and safety-related warning events. The first major issue was a single occurrence of an overheating condition that displayed an “Engine Overheating – Idle Engine” warning. After that event, the vehicle was taken in for repairs. Following the repair attempt, the vehicle began displaying repeated check-engine warnings and multiple occurrences of “Engine Power Reduced.” During these episodes, the vehicle lost acceleration ability and hesitated. One of the “Engine Power Reduced” incidents occurred while driving at highway speeds with a passenger onboard. The vehicle was unable to maintain speed and required pulling out of active traffic, creating a safety risk. These issues have continued despite previous service attempts and diagnostics. The warning messages and power loss are unpredictable and create a potential hazard, especially during highway driving, merging, or transporting passengers. There has been no crash, fire, or injury, but the repeated sudden loss of power presents a serious safety concern.

While driving my 2013 Chevrolet Malibu, the electrical system intermittently fails: the radio shuts off, the instrument cluster goes blank (gauges drop to zero, fuel/temperature show empty), headlights flicker off then on, and turn-signal indicators disappear. Warning messages such as “Service Theft” and “No Key Detected” appear, power steering becomes difficult, and the vehicle shakes, stalls, or even turns off completely at stop signs. Sometimes the engine continues running even after the car is shut off, overheating and producing a burnt smell. These failures began months ago, occur unpredictably, and have been witnessed by an independent shop. The loss of lights, steering, and cluster data creates a serious safety hazard, and the vehicle is available for inspection.
