I purchased the vehicle in July 2024. I drove the car for 10 days, and when I was driving 65 mph, the check engine light blinked three times and then went off. After that, the engine made a sound that was not there before. I took the vehicle to the dealership and they had the car for many weeks, concluding that the lifters broke and the engine needed to be replaced. The dealership said they replaced the engine and the car was returned to me towards the end of August. Since then, the AC has been worked on three different times in the past year and on the third attempt, there is finally cool air coming out of the driver's air vents. The driver's seat AC blowers malfunctioned and were repaired. The dealership put the original engine's belt back on and then broke. The electric system inside glitches from time to time when you first start the car. The front windshield wipers will randomly swipe while driving. After getting a regular oil change, the car sprang an oil leak due to the cap not being tight enough. Over the past 5 months, there has been a random popping sound in the front driver's side area when coming to a stop that two dealerships can not figure out. The belt in the engine still makes a high-pitched sound when first starting up and lasts for about 1 minute. While in park or sitting at a light, the engine will idle up and down from time to time. The vehicle has been worked on by the dealership where it was purchased and also a GMC dealership.

In January 2021, I purchased a new 2021 GMC Yukon Denali from a GMC dealership, which currently has only about 27,000 miles. To date, several recalls have been assigned and completed for my vehicle. per the websites for GMC and your agency. However, based on published recalls for my vehicle and a repair that is currently underway, I have reason to believe that my vehicle should have been subject to three prior recalls for which it was not [NHTSA ID Numbers: 20V735000 (Front Seat Bolts), 25V274000 (V8 Engine Failure, and 21V739000 (Fuel Power Control Module] Currently, the fuel pump control module is being replaced at a local GMC dealership because it failed last week and left my stranded at home. GMC issued a recall for this in 2021, but my vehicle was not included. Aside from risk and inconvenience, this is also costing my over $300 for a rental. Secondly, though my vehicle's make/model/year is cited in GMC's ongoing engine failure recall, which you are investigating, I have not received a recall notice. I note GMC's financial interest in minimizing vehicle's it recalls for such a costly repair. I have inquired with GMC and two of its dealers and have only received reiterations that my vehicle has not been subject to GMC's recall, which I already knew. I have not been given any explanation for why my Yukon has not been recalled despite my inquiries. Lastly, GMC issued a 2021 recall for front seat bolts; however, I did not receive a notice for my Yukon. I have occasionally felt slight movement in the driver's seat since buying the vehicle. Based on reason and facts, I am alleging that GMC appears to be artificially minimizing recalls and notifications for vehicles that are in fact impacted by defects in their vehicles.

Service Safety Restrain System message keeps appearing after taking to dealer a few times. It will go off and on intermittantly and not sure the airbags are actually functional. This seems to be a common issue based on an internet search across multiple GM products that does not have a known fix. Also, the driver seat shifts slightly when making turns.
