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!

I understand that the vehicle is outside of its original warranty period. However, I do not believe that the expiration of the warranty should automatically make me responsible for a component failure that occurred at only approximately 39,000 miles. The PCV valve and orifice are not routine maintenance items that I would reasonably expect to require replacement at such low mileage. Unlike tires, brake pads, batteries, or other components that are expected to wear out and require periodic replacement, the PCV system is an integral part of the engine's emissions and crankcase ventilation system. A failure at only 39,000 miles seems premature and should not reasonably be characterized as ordinary wear and tear. More importantly, GM itself has acknowledged problems involving the PCV system in Chevrolet Malibu vehicles. GM Technical Service Bulletin and TSB 18NA246 and TSB 20-NA-047 specifically addresses plugged PCV orifices on 2016–2022 Chevrolet Malibu models and provides a diagnostic and repair procedure for this condition. The bulletin identifies the PCV orifice as the causal part associated with the condition being addressed. I recognize that a Technical Service Bulletin is not the same as a recall or an extension of the vehicle's warranty. I am not claiming that GM is necessarily obligated to repair the vehicle under the expired warranty. Rather, I believe GM's own technical documentation demonstrates that this is a recognized issue involving a specific component and is not simply an ordinary maintenance item that a customer should reasonably expect to replace at 39,000 miles. The approximate cost of this repair is $1300 for a failed $40 part!! Even GM changed the design of this component because in years past and newer years this part replacement was a 20 minute job, not a 5 hour complete replacement of the valve cover! Failure to repair this faulty design could lead to excessive oil loss and immediate loss of power due to the engine ceasing.

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.

The Chevy Malibu is displaying a “Shift to Park” message even when the gear selector is physically in the Park position. This indicates that the vehicle’s computer may not be recognizing that the vehicle has been placed in Park, which is commonly associated with a faulty or failing internal park-position sensor/switch. The issue is affecting the vehicle’s ability to shut down properly. It is necessary to turn the vehicle off and back on multiple times before the system will recognize that the vehicle is in Park and allow it to shut off completely. If the vehicle does not recognize the Park position, it may remain partially powered on and potentially drain the battery.

While driving my 2015 Chevrolet Malibu on a four-lane highway with a posted speed limit of 70 mph, the vehicle displayed an “Engine Power Is Reduced” message and limited the vehicle to less than approximately 25 mph. This created a serious safety concern because the vehicle could no longer maintain highway traffic speed, resulting in a significant speed differential of nearly 45 mph below the posted limit and surrounding traffic flow, creating a high risk of being struck by other vehicles. The vehicle also experienced an alternator problem while being driven on the highway. It repeatedly acted like it was not getting enough power to maintain the speed of surrounding traffic, and we had to pull over on the side of the road. The vehicle has also had an engine-related issue discovered during repairs. When the valve cover gaskets were replaced, the vacuum pump was found to be severely damaged, and metal shavings were found in the engine oil. The reduced-engine-power problem has occurred in connection with the vehicle's electrical and engine problems. The vehicle and affected components may be available for inspection upon request. The vehicle has been inspected during repairs, and the damaged vacuum pump and metal shavings in the oil were observed during that inspection. These problems create a safety risk because the vehicle can suddenly lose engine power and become unable to maintain highway speed. The loss of normal power while traveling on a four-lane highway could make it difficult to accelerate, merge, or get out of the way of other vehicles.
NHTSA complaint #11757229 — an unverified report by a vehicle owner.
The contact owns a 2018 Chevrolet Malibu. The contact stated that there was an abnormally strong gasoline odor coming from the vehicle. The contact stated that while driving at various speeds on several occasions, the accelerator pedal was depressed, but the vehicle failed to respond, requiring the driver to pull over to the side of the road. The message "Engine Power Reduced" was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the fuel injectors had failed and needed to be replaced. The mechanic retained the vehicle and informed the contact that it was unsafe to drive due to a potential fire risk. The vehicle was not repaired. The dealer was contacted and confirmed that the VIN was not under recall. The dealer advised the contact to bring the vehicle in for service. The manufacturer was notified of the failure and confirmed that the VIN was not under recall. The failure mileage was approximately 169,000.
NHTSA complaint #11755237 — an unverified report by a vehicle owner.
I own a 2018 Chevy Malibu. At approximately 57,000 miles, the original engine experienced a vacuum pump failure that resulted in catastrophic engine damage. The engine was replaced by General Motors under the vehicle's warranty. I then drove the vehicle for approximately another 52,000 miles with the warranty replacement engine. At that point, I experienced a sudden loss of braking while driving. My vehicle was again diagnosed with a vacuum pump failure, and the vacuum pump was replaced. Approximately one week after the vacuum pump replacement, the warranty replacement engine suffered catastrophic failure. The repair facility diagnosed cylinder #3 scoring and informed me that the engine required replacement. I was told that the engine failure was related to the vacuum pump failure. Because the warranty replacement engine was no longer covered under warranty, General Motors initially declined to cover the repair. Initially, neither General Motors nor the Chevrolet dealership was willing to accept responsibility for the issue. After continued discussions, General Motors ultimately agreed to provide partial financial assistance as a goodwill adjustment. However, I was still left responsible for paying a substantial amount out of pocket to purchase and install a third engine. The cost has created a significant financial burden that I have struggled to afford, especially because the repair involved a component that I was informed has a known history of failure. I was also informed that vacuum pump failures are a known issue with these vehicles and that General Motors is aware of the problem, although no recall has been issued. I am submitting this complaint because I have experienced multiple vacuum pump failures, two catastrophic engine failures, and have now required three engines in the same vehicle. This has resulted in significant financial hardship, loss of use of my vehicle, and serious concerns about the safety and reliability of this vehicle.

I’ve reported this problem but as I got into the repair their was far more damaged that was caused due to the vacuum pump. It took out my exhaust camshaft and sent metal through out and the timing needs replaced as well. A shop would rather total my car than what it would cost to fix. I’m attempting to fix it myself but have been without my car for months now. This is created such a hardship and the money it’s continues to take as more and more needs to be fixed or replaced as well as all the gaskets and screws that are only one time use as well as parts like my high pressured fuel line I mean this lost keeps going. I and to replace the water pump as well and all due to this vacuum pump that’s been reported and reported and nothing has been done this is outrageous that what’s caused is so much more then just a vacuum pump it can destroy your vehicle miles don’t matter the less or if you have more the pump goes out when it feels like it. Creating more issues then it should and potentially totaling out a vehicle as it’s been said mine should be. So I’m trying to fix my car to prevent losing it and it’s been one thing after another and such a nightmare. The fact that this issue continues to be ignored is unacceptable and a complete disregard to public safety due to the serious safety issue as mine I could barley get my car to stop the breaks were hard and unable to push down without basically standing on them to get into stop at only 7-8 miles per hour I was moving when the vacuum booster went out. Someone should not have to die to have this issue addressed and to be taken seriously and made right! I can’t believe nothing has been done and that it’s not required to have to address this issue with the severity it bring to one’s safety as well as public safety is beyond me. This is a major lawsuit and people’s lives and lovely hood should be taken more seriously and instead nothing is being done. It’s very concerning to think what has to happen for this to be addressed!

was stopped at a red light. When the traffic light turned green, I pressed the accelerator to proceed through the intersection, but my vehicle did not respond or accelerate immediately. After several seconds, the vehicle finally began to move. This unexpected delay created a safety concern because I was unable to accelerate when traffic began moving.Which caused built up traffic and an almost wreck behind me
NHTSA complaint #11751301 — an unverified report by a vehicle owner.
While coming down McClure pass in Colorado my brakes failed. The the car went to engine power reduced mode. After getting the car to an independent mechanic I was told that the vacuum pump failed and exploded the parts into the camshaft. After 2 days of repairs I was finally able to get my car back to working order. This could have been a fatal car accident coming down a mountain pass. I was able to get stopped safely because I know the road. I had just driven 700 miles over Eisenhower Pass, Vail Pass, Glenwood Canyon, and then the final pass being McClure pass where it failed. I bought this car brand new and I probably won't buy another Chevy after this. This was a terrifying experience that I will have lasting trauma from.
