2017 Chevrolet Malibu

I am writing to report a persistent issue with my Chevy Malibu, specifically related to the Stabilitrak system. The Stabilitrak light intermittently flickers on and off while driving, which raises significant safety concerns. This malfunction has been ongoing, and despite efforts to diagnose the problem, my local auto mechanic has been unable to pinpoint the exact cause. Services Performed: Initial diagnostic checks were conducted to identify any fault codes related to the Stabilitrak system. The mechanic found no definitive issues but noted that the warning light's behavior indicated a potential underlying problem. Each visit has led to additional uncertainty, with suggestions from the mechanic to proceed through the GM flow chart for further diagnosis. However, this approach may lead to extensive labor costs with no guaranteed resolution. Financial Burden: The recommendation to follow the GM flow chart for diagnosis is concerning, as it may result in significant and unnecessary expenses without a clear outcome. As a consumer, I believe that a properly functioning diagnostic system should provide clarity on such issues without incurring exorbitant costs. The erratic behavior of the Stabilitrak system poses a serious safety risk while driving. This system is critical for maintaining vehicle stability, particularly in adverse conditions, and its failure could lead to loss of control of the vehicle. I have been made aware of other drivers experiencing similar issues with their Chevy Malibu vehicles. It raises the question of whether there is a known defect in the Stabilitrak system that warrants a recall. I urge the NHTSA to investigate this matter further, as it seems that GM has not taken the necessary steps to address these concerns

On Thursday, [XXX] my [XXX] son was driving my chevy malibu coming down the hill to get home when the brakes went out. He could not stop the vehicle and had to pass our neighborhood and let the vehicle slow itself down. He was able to get stopped and turned around and made it home. Saturday, [XXX] we decided maybe it needed new brakes and took it for new brakes. New brakes and rotors all the way around did NOT fix the problem. The brake was like hitting a brick and would not stop the vehicle. I had the vehicle towed to a repair shop and they found that the vacuum system for the brakes went out. He also noticed that cam shaft was cracked. Upon research through the internet I found that this problem is common and a class action suit has been filed against GM for the same problem. I am unsure why this is not a recall as its a safety issue and my son could have been injured or injured someone else. This has been an EXTREMELY expensive repair for us! When they went to replace the cam shaft there were several parts of the cam shaft just blown all over the engine. We still have not found all of the missing parts. This has caused most of the seals to have to be replaced as well. I do not have a repair receipt yet as the vehicle is still in the shop INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Power Brake Vacuum Assist Failure nearly caused a wreck. The part failed while we were driving on [XXX] going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “Reduced Power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an HEB parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.
