While shifting my vehicle from Park, a "Service Transmission" warning message appeared on the dashboard. The warning would illuminate and then disappear, but the vehicle continued to shift into the other gears. At the time the issue occurred, my truck had only 47,000 miles. I brought it to Blasius Chevrolet in [XXX] on XXX, for diagnosis. The dealership determined that the Transmission Control Assembly (Part # XXX) had failed and needed to be replaced. I was informed that this repair was not covered under the powertrain warranty because Chevrolet considers the Transmission Control Assembly to be excluded from powertrain coverage, and my basic warranty had already expired. I was quoted more than $900 for parts and labor. Initially, I was told the replacement part would arrive within a few days. Later, the technician stated that other Chevrolet dealerships had the part in stock. However, after contacting those dealerships, he was told they would not release their inventory. Chevrolet then advised that the part was on national backorder, with the earliest estimated availability of XXX. As a result, I have been without my truck for approximately one month, creating a significant hardship. After researching this issue, I found numerous reports from other Chevrolet owners experiencing the same failure involving the Transmission Control Assembly. The apparent frequency of these failures, combined with the nationwide backorder of the part, suggests this may be a widespread defect rather than normal wear and tear. I believe Chevrolet should either: Cover this repair under the powertrain warranty, as it directly affects the operation of the transmission, or Issue a recall or warranty extension if this is determined to be a common defect affecting vehicle safety and reliability. I am submitting this complaint because I am concerned that a failure of the Transmission Control Assembly could impact the safe operation of the vehicle.

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

I have a complaint about GM and my 2023 Chevrolet Silverado 1500 LTZ regarding the radio / infotainment system failure after attempting a recommended software update, and the resulting degradation of installed safety features. On 08 MAY 2026, my infotainment system indicated a software update was necessary, so I followed the directions to complete the update. When the update was complete, my infotainment screen said there was a failure and to take it to the dealership for repair. The entire infotainement system is inoperative. The soonest appointment I could make was for 18 MAY 2026. On 18 MAY 2026, I took my Silverado into the dealership where I have it serviced to address the failure of my infotainment system. My service advisor informed me that I would need a new radio and that these radios are on a national backorder list. My advisor informed me that they have other customers who are experiencing the same issue and have been waiting for the replacement radio since January 2026. My advisor informs me that there is no estimated time of resolution. This defect inhibits safety features such as; use of OnStar, Google and Apple Maps that provide travel advisory hazards, parking camera views, vehicle systems status. Thank you.

My truck has the L87 motor on recall. i purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, i do not take my family out in my truck because i am not confident in its reliability and safety. multiple times i've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6.2". my normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, i'll squeeze you in" in which i did. however, i wasn't given any documentation since "i didn't have an appointment". After reviewing all of my service records, i come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating GM recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. when i called to ask the status i had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since i need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. i feel that they are brushing me off to buy time and here i am making hefty car and insurance payments for a truck i do not have nor a truck that I NEED to provide for my family. GM does not care!
