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.

I bought this car about 10 days ago. Throat was in pain, coughed up blood, dizzy, sweaty, and shaking. There's gas all over the ground coming from front under hood smelling through the vents. Very loud smelling. Took it to Chevrolet dealership on Covington hwy Decatur GA today and had to leave it there. I still don't feel good and neither the passengers in car. Car could've caught on fire gas leaking out when put in. Never experience this ever in my life. I may have to go to the hospital my chest feel very tight and I had a chronic asthmatic and my child in the car with me that's been on a breathing machine since last night and it's now 3:35 pm next day.

The vehicle is experiencing premature clear coat failure on the hood and roof. The affected areas show widespread oxidation, dulling, and breakdown of the clear coat, while vertical panels remain unaffected. This indicates failure limited to UV-exposed surfaces and does not appear to be normal wear. The condition is uniform across the panels and not caused by impact, chemicals, or improper maintenance. I have observed similar clear coat failure on other 2016 Chevrolet Malibu vehicles, suggesting a potential pattern or manufacturing defect affecting paint durability. The issue significantly impacts the vehicle’s exterior condition and resale value and continues to worsen over time. Photos are available documenting the condition.

On 04/28/2026, when diagnosing a reoccurring check engine light on the vehicle at a Chevy Certified Service, the mechanic "Borescoped cylinder 4 and found significant scuffs on the cylinder wall which along with the misfires indicate a cracked piston. The big picture appears to be the piston cracked which caused excessive oil consumption and misfires. The excess oil and unburned fuel overloaded the converter causing it to fail. The engine and converter will need to be replaced." In 2017, a recall was issued by GM to mitigate Stochastic Pre-Ignition (SPI) Causing Cracked Piston (17019). Between the initial purchase of the vehicle (11/2016) and performed service required by this recall (03/10/2017), there were approximately 5000 miles driven. No engine diagnosis was performed or recommended. After the 17019 was addressed, the engine misfires continued along with reoccurring CEL. C.S.P. N182195660 Predictive Monitoring for Stochastic Pre-ignition (SPI) released in 2019 states the 1.5 L LFV engines in certain 2016 and 2017 model year Chevrolet Malibu vehicles may have a preignition condition that requires immediate repair. This condition may cause the engine to perform poorly, misfire, run rough, and/or excessively consume oil. It may also illuminate the vehicle’s service engine light. Over time, if not repaired, the condition can damage the vehicle’s pistons and engine. The VIN for this Malibu was not attached to this notice despite it having SPI recall history. On 06/2023 (after the N182195660 program ended), at 80k miles a diagnosis revealed a potential cracked cylinder with no mention of the pre-ignition condition that could cause the crack, and the only way to fix is to replace the entire engine (as per dealer recomendation). Since vehicle was out of warranty, the repair est. was nearly $10k. I firmly believe my 2016 Malibu has suffered the consequences of poor mismanagement on this recall, and am demanding mitigation from GM to fix this issue.

My car will rev up to 4000 rpm’s and my car will not go about 20 mph. My cruise stopped working after my car went into reduce engine power. The dealership said they fixed all issues but was back to doing the high rev within a week. It started this week telling me to shift to park even though my car was in park. The shift to park cable has been replaced twice now. I have been dealing with this since July of 2025. My car has been in the shop more times than I can count.

I am reporting a recurring safety defect related to GM’s known “Shift to Park” issue. My vehicle displays a “Shift to Park” warning even when the vehicle is already in park, preventing the car from shutting off properly and creating a safety risk. This issue has been widely reported and associated with GM recalls and service bulletins. GM previously repaired this issue once while my vehicle was under warranty, acknowledging it as a known defect. The same defect has now reoccurred after the warranty period expired. GM is refusing to repair it again, despite the issue being recall-related and tied to a known defective design rather than wear and tear. This defect affects safe vehicle operation, risks battery drain, rollaway hazards, and driver distraction. I believe this is an unresolved safety defect that should be covered regardless of warranty status.

NHTSA ODI 11708443

While driving, the vehicle experienced a mechanical failure involving the engine and lubrication system. Oil leakage was observed, and the engine began operating abnormally. This created a risk of sudden engine failure while the vehicle was in motion, which could result in loss of power, stalling, or loss of control, especially at highway speeds or in traffic. Prior to the failure, warning signs included abnormal engine behavior and fluid loss. The issue was not caused by driver error and occurred during normal operation. Continued operation in this condition presents a fire risk if oil contacts hot engine components. The problem has been inspected by a repair facility, and the failure appears to be related to a mechanical or manufacturing defect rather than wear or misuse. The component is available for inspection upon request. This defect poses a safety risk to the driver, passengers, and other motorists due to the possibility of sudden engine failure, loss of propulsion, or fire.

On December 16, 2025 the check engine light and service stabiltrek warning light appeared on my 2016 Chevy Malibu Hybrid. On December 17, 2015 I took the car the Capital Cheverolet service dept who has been servicing my car regularly for the past five years. They performed a complete diagnostics on my car that determined I need to "replace the EBCM with brake pressure modulator valve" and said it would cost over $2800.00. Upon further research I discovered that the same make model and year was recalled under recall #39440. I also learned the my VIN number was not included in this recall. This is a safety defect that has rendered my car not drivable until I get it fixed. As a senior citizen on a fixed income I am unable to fixed. I would like to know why was my car not included in the recall and if its possible to get it on the recall list so it can be fixed.

The vehicle went into shift to park and will not turn off. This is a known problem with ALL GM vehicles that hasn’t been fixed or offered a warranty for. It’s dangerous and causes the car not to move shut off in traffic and drains the battery. My car currently isn’t working due to this issue and the repair to fix is too much with no assistance from GM for a known defect. My car was almost hit because of the car had to be towed because it’s unable to be moved.

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 NHTSA 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.
