Recall N252494000 GM has known about this issue since January (at least) and issued a recall in April. The attached form indicates they are recalling my vehicle but they are unable to repair it. This reduces my value and potentially leads to serious accident and serious injuries. How can GM get away with this? It is a BIG DEAL for a customer to have their vehicle recalled for safety issues like this but not have the manufacturer come out with a fix? What are we as customers to do? Wait until we or someone we love are injured or killed? Please, act quickly! Perhaps a full value buyback offer? Or actually replace the engines that they already know are defective. Changing the oil viscosity as indicated at various online sites DOES NOT FIX THE PROBLEM. Please advise what recourse I should seek. Thank you very much!

I was driving on an interstate highway. I entered a construction zone restricted to two lanes.(one each way). It began to rain very hard, after a short time of starting the front windshield wipers; both stopped. There was a total failure of both wipers with out any warning and a total loss of vision due to a rain covered windshield. Due to the restricted traffic lanes in the interstate construction zone there was no shoulder on either side to pull off onto and no way to exit the interstate traffic flow for several miles. I was able to avoid a crash and exit the interstate after several miles. With a different driver, slightly different circumstances or a little less luck it would have resulted in LOSS of LIFE!!!! The cause was failure of the wiper arm linkage more specifically the ball broke off of the wiper motor arm. THIS APPEARS TO BE THE SAME FAILURE THAT CAUSED A RECALL TO BE ISSUED FOR PREVIOUS MODEL YEARS OF THE GMC TERAIN. The parts are available for inspection.

Intermittently there isn't any sound from informational center speakers, this includes not sound of the turn signal indicators working. No sound from any vehicle component, vehicle has the current software release from GM. the only way I've found to get sound again is to leave the vehicle set not running for some period of time, short off then back on doesn't seem to clear the issue. I've check with the dealer and from what I understand this is a known issue with 2024 & 2025 GM informational centers.

On March 10, 2025, I was driving down a residential street, about 40 mph, when the "Brake System Failure, 42 miles top speed," indicator light came on. Seconds later, I was approaching a stop sign and pressed down on the brake pedal. The brakes failed and the brake pedal went directly down to the floor. Luckily there were no other vehicles around and i was able to coast through the stop sign. I continued to coast until the truck stopped on its own and I was able to shift the gear into park. I've checked for recalls on my truck for this issue and did not find any. There is a similar issue with the GMC 2500 and 3500 series. Perhaps the issue is broader than expected.

I was driving with my wife about to merge into traffic on the interstate when I had a huge power loss. It was a busy part of the interstate where I could have been ran over. There was a lot of traffic and was fortunate the Semi driver was alert and slowed down. I was not aware of any failures of this motor or received any notices from GM. After conducting research I found that this was a know issue that GM failed to report. My truck has been serviced regularly and until that point had not given any signs of a upcoming failure, I have read that GM is looking into other years such as 2019 which mine is. I have had no luck with GM customer care with the only response being I need to crunch the numbers from my claim advisor. I have the 6.2 L87 motor and know of the clip failure do to poor assembly and parts and debris getting into the motor causing the failure. I am looking to report this and request any assistance available. My first stop was the dealership, then GM customer care

This 2012 GMC Acadia denali with close to 160k has been in the shop several times due to it randomly stalling out It kept basically locking me out from starting the car a "service anti-theft system" would flash across the dash followed by a flashing check engine light along with a lock and key symbol. A local GM repair shop had it in 3 times for them to tell me they couldn't figure it out or get the vehicle to "act up" they cut me two new keys and tightened up what they claimed to be loose battery cables just for the vehicle to die/stall with a no crank no start happen literally 10 minutes down the road after paying almost 600$ for repairs and that it was towed back 3 times for the same issue spanning over two months of them not being able to figure out the issue. Salvador ended up replacing the anti-theft control module after the 3rd time having to tow it back and forth just to leave the shop and I couldn't start the vehicle the next day after handing over almost another 400$ and less than 15/20 miles of drive time. GM needs to get this issue figured out!!! There anti-theft system locks people out from starting their vehicles more than it does actually preventing actual theft. This will eventually end up causing a major crash at an intersection or highway if the anti-theft system keeps failing it just randomly cuts out power to the engine while driving.
