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

A "Shift to Park" message occasionally appears on the dash of my 2017 Chevy Malibu. I currently have 56570 miles on this vehicle. This is the second time that this issue has occurred in this vehicle. The first time it occurred I had 21849 miles on the car. On Dec. 20, 2019, a local Chevy dealership replaced the shifter (8460140 transmission electronic control replacement) at no charge since the car was still under warranty. My warranty is now expired but the same problem has occurred after putting less than 35000 miles on the car. Since this problem started, my back driver's side door will not always lock. This problem may be related to the Shift to Park issue. I have my invoice from the dealership where I first had this problem fixed and am hoping they will fix it again at no cost to me. When I searched this issue online, it appears to be a problem with many 2016-2019 Chevy Malibus. There should be a recall issued by GM for this problem. This is a safety issue because the problem will cause the battery to continuously die and the vehicle to remain running although the shifter has been placed in the Park position.

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)
