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.

My 2016 Chevy Malibu Limited is experiencing Electronic Brake Control Module (EBCM) failure symptoms that match Recall 39440, even though my VIN is not listed in the recall. Details of the problem: -The brakes would randomly feel like they were sticking and the car being held back -Brake lights would remain on -Car would float all over the road -ABS and StabiliTrak warning lights illuminated in the dash once. -ABS and ESC functions stop working, leaving only based braking available. -These failures occur intermittently but increased to everytime. -All 4 brakes are dragging, pulsing (no lights illuminated), reaching 240 degrees -Confirmed by mechanic EBCM This is a safety hazard. The vehicle becomes more difficult to control in adverse conditions without ABS/ESC. I transport my special-needs child in this vehicle, and I am deeply concerned for our safety. Why I believe recall expansion is needed: GM has acknowledged this exact defect in Recall 39440 (affecting other 2016 Malibus built during specific production dates). My vehicle is showing the same failure, and I request NHTSA investigate whether the recall population should be expanded to include additional VINs.

When I was driving my car with my child in it my break tightened up and I couldn’t apply them to stop I had to let my foot off the gas and let my car slow its self down safely. When I got my car home my husband looked at it and found out that my vaccum pump had went out and part of it broke off in the engine. This is very unsafe and this needs to be investigated because people can’t know when the vacuum pump is going to go bad this issue lays on gm and Chevy to make sure the parts they are using will hold up and be safe

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.

I am having to replace the VACUUM PUMP for the second time. Each time the pump breaks it spreads contaminants inside the camshaft compartment causing further issues. This is a common problem according to the many complaints I've seen on auto sites. This should be a recall.

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.

I am very upset right because I purchased this Chevy Malibu 2016 from Vroom. It was fine at first and then things start to go downhill. For starters my tire light came on first only a week after having the car, then the shift into was appearing on the dashboard as well as the engine light. Then my husband spent almost 2000 on the brakes because the car was making this horrible sound and I almost couldn't stop the car because the pedal was stuck and would not push down. Thank God no one was hurt. Then my car just shut off twice one day at a busy intersection, it went completely dead with my children in the car. This is a ongoing issue. Now I had a diagnostic test ran on my vehicle and it was said I needed a new motor only after having the car for only a year. This car is very dangerous and I wish they would take it off the market, because it will also reduce your speed while driving out of nowhere. Chevrolet should be responsible for all problems before they are aware of these issues!

I took my car to to Firestone to have the brakes checked because I had a stiff brake pedal and could only use my emergency brake to stop. They did a basic and advanced diagnostic and said that the brake booster that I have has been recalled and also other equipments on my car has been recalled and I must bring it to a dealership. I searched my VIN and nothing popped up even though months ago I was emailed a recall notice on the fuel pump system and Air bags and it has never been repaired in my car even from the past owners.There have been 10 recalls from Malibu's manufactured in 2016 and my car shows every sign and indication that it is one of those few selected. My VIN should be updated or investigated for parts in my vehicle that have been recalled. The Car stops when idle for two minutes or longer and shuts off the engine and air if you use the USB outlet there is a serious electrical problem which is also a safety hazard according to NHTSA guidelines.
