2016 Chevrolet Malibu Electrical System Problems

My car caught on fire under the hood. As I was driving on road I heard a sound and my car started slowing down and smoke started coming from under the hood got out the car not a minute later flames of smoke engulfed the car

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.

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.

INTERMITTENT SHIFT TO PARK MESSAGE DISPLAYED WHILE VEHICLE IN PARK. TWO STATES HAVE SUED AND WON TO HAVE THIS SAFETY PROBLEM TAKEN CARE OF BY GM. (OHIO AND TENN.) SHOULD BE A RECALL ITEM. WHY NOT. GM SERVICE BULLETIN 19-NA-206, MARCH2024

2016 Chevy Malibu is experiencing a “Shift to Park” issue, where the car does not recognize it is in Park even after shifting correctly. This prevents the vehicle from turning off, leaving lights and electronics running, which can drain the battery. A service advisor at AutoNation Chevrolet Orlando confirmed this is a common problem in GM vehicles like the Traverse and Silverado. She explained the repair—replacing the faulty sensor/shifter assembly—typically costs around $800. Beyond battery drain, there are safety concerns, since the system’s failure to recognize Park could risk the car rolling if the brakes disengage. The issue first appeared about four months ago, went away, and has now reoccurred.

Vehicle isn’t recognizing that it’s in park, shift to park keeps coming on dashboard which is also causing my vehicle not to change gears correctly

Have been getting reduced engine power since the summer on and off. Check engine light says its throttle bottle sensor and accelerator pedal position sensor. Which I was told there was a recall but my vin isn’t listed

Stability track warning randomly appears while driving and spontaneously causes total brake failure and the brakes fail to slow or stop vehicle. It has newer brakes but it’s very dangerous to drive. Currently being sent to Chevrolet dealership

When I put the car in park and try to turn the car off the Shift Park message comes on preventing me from cutting the car completely off. I put in back in drive or reverse then back in park it still dings and shows the message. I takes a number of repeating these steps for it to stop and turn off and this is happening every time I'm trying to turn the car off.

To whom it may concern, I am writing to formally report a recurring safety-related issue with my 2016 Chevrolet Malibu. The vehicle consistently displays a “Shift to Park” warning message, even when the gear selector is properly in the Park position. This malfunction prevents the car from turning off completely and poses a serious safety and reliability concern. This issue first occurred while the vehicle was under warranty, and the dealership performed a repair. However, the problem has returned, and my warranty has since expired. Despite the previous fix, the issue continues to persist. This malfunction is widely documented among other 2016–2019 Chevy Malibu owners and appears to stem from a design or manufacturing flaw in the shifter assembly or park switch. I am concerned that this defect could: Prevent the vehicle from being securely parked. Lead to battery drain due to the vehicle not shutting off. Pose a risk if the driver believes the car is in park when it is not. I am requesting that Chevrolet consider this a safety defect and either recall the affected vehicles or offer extended coverage for repairs. I also ask that NHTSA investigate this issue further as it compromises the safety, reliability, and proper functioning of the vehicle. Thank you for your attention to this matter. I would appreciate any assistance or updates regarding how this issue will be addressed.

Shift to park message and park not fully engaging. This caused the vehicle to roll back when parked on an incline.

The check engine light came on and we brought it to the shop where they said the code is for the electronic brake system modulator. It is also causing the ABS to malfunction and be hypersensitive. There is a recall for the same make/model/year of vehicle, except the month before her car was manufactured. I believe this is a safety issue that needs to be looked into and that her car should also be a part of this recall. We purchased the car in mid November and the engine light showed up a couple weeks later. I contacted GM who said to contact this site to request further investigation for safety risks.

Took my car to Chevy dealership to diagnose my car, as it was rough idling, causing hesitation, and knocking... all while the check engine light was on. They showed me two codes my car was giving from the check engine light. They said he would look further into it. They told me I needed a tune up, though I had gotten a tune up 4 months prior. They fixed some things and charged me over $4,000. The day I drove off the lot, the problems were still present. On my way home going about 50 mph, my car slowed down and the engine reduced power illuminated. I kept driving because I needed a car for work. The car continued to decline and acted like it didn't want to accelerate when pressing the gas. I finally took it back into chevy, and they told me it was my pistons. I'm 90% sure there is a defect that they won't tell me about, or the won't fix. I've had the car 2 years. Now the car won't run.

I experienced a check engine light and a "reduced engine power" message in the middle of traffic in the stromy rain. I was driving 35 to 40 mph before vehicle slowed to almost a stop and when pressed gas pedal it excel slowly creeped to less than 30 MPH THANKFUL I wasn't rear-ended.Pulled into nearest Autozone part store and diagnostic scan showed the P2138 code. DC severity, sensor, and accelerator pedal position - see photos attached. Waited with engine off for approx over 30 minutes then started vehicle , engine lght off and proceeded to my destination excell with no issues.This has happened several times since purchase of vehicle began 2019. Throttle body repairs, ECM replacements and harness repairs later still reoccurring documented at dealships and repair shops. This is a serious and costly hazard.

“Shift to park” intermittently indicated when vehicle is in park. Power will not shut off while indicated. Was repaired twice but has returned

There’s a warning on the display that says ‘shift to park’ while the vehicle is already in park. This is causing the battery to drain/die and needs jumpstart everyday. Battery was tested and does not need to be replaced. I’m surprised this hasn’t been recalled yet. Online search ‘Chevy Malibu shift to park’ shows this is a common problem. Here’s a YouTube link that includes comments to prove this further. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car has a seat belt electrical problem it makes sound once in a while indicating for the driver to put their seat belt on. Also there is issues with the brake sensor. The #1 issue is the Transmission Accumulator Pressure Pipe, when it breaks all your transmission oil pours out from the bottom of the vehicle. The part is about $20 but if not installed right you will think that your transmission is dead but it's not.

The electrical chip in my EBCM has a malfunction and the brakes will grab and grind at random times. Also at the time electronic stability control will mess up increasing the risk of a crash. Other malibu vehicles with the same year have had a recall on these parts. Mine however was not included but has the same malfunctioning part.
