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!

What owners say
The vehicle is experiencing an apparent fuel-system malfunction. The vehicle has a very strong raw gasoline odor, significant difficulty starting, and appears to be consuming fuel at an abnormally high rate. After filling the fuel tank completely, I drove approximately 20 miles at most and the fuel gauge decreased by approximately one-quarter of a tank. The engine oil also has a strong gasoline odor, indicating that fuel may be entering the engine oil. The exact failed component has not yet been diagnosed. The vehicle is available for inspection upon request. The strong raw gasoline odor and apparent rapid loss of fuel create a concern for a fuel leak and potential fire hazard. The vehicle also has difficulty starting and shuts the engine off when the automatic stop/start system activates while stopped at a traffic light. This creates a safety concern because the vehicle may not restart normally when traffic begins moving. I am concerned that the vehicle may have a fuel-system defect similar to the high-pressure fuel pump/fuel-line issue previously recalled on certain 2016-2018 Chevrolet Malibus. No. The problem has not yet been diagnosed or confirmed by a dealer or independent service center. The symptoms have been personally observed while operating the vehicle. This was my first step as this happened at 10:30pm. No. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another official representative. I am reporting the problem because of the severity of the symptoms and the potential safety risk. There were no warning lamps or messages that I noticed before the problem occurred. The first symptoms were a very strong gasoline odor, unusually rapid fuel loss, and significant difficulty starting the vehicle. The vehicle also shuts off completely when the automatic stop/start system activates while stopped at a traffic light. These symptoms began recently.
