I am writing to express my significant concerns regarding the recurring issues with my 2024 Denali 6.2, which has been subject to multiple service visits since reaching 7,000 miles. Despite these visits, the underlying problem remains undiagnosed and reoccurs shortly after I retrieve the vehicle. Following the second oil change, the engine developed a persistent ticking noise. Over the past 13 month, I have invested over $200,000 with your dealership in the past 5 years!. My truck was recently held for two weeks for service. After I lodged a complaint, the General Manager suggested I seek service elsewhere. This recommendation was made after I responded to an email stating that, following the completion of repairs to the headliner, third brake light, and brakes/rotors, I would no longer be utilizing Crain's services. The headliner sustained water damage due to improper installation by your technician, and fingerprints were also evident. I firmly believe in transparent communication regarding service progress, which was notably absent in this instance. Both the General Manager and Service Manager deferred responsibility, instructing me to contact GM directly, only for GM to inform me that direct contact was inappropriate. This resulted in a continuous cycle of unaddressed concerns with the service manager. Currently, I am operating an $80,000 vehicle that has incurred damage from a technician and exhibits a ticking engine. Furthermore, the driver's side mirror, which was previously replaced due to shaking at highway speeds, is now exhibiting the same issue, despite a technician's assertion that this is normal. I also note that my brakes, with over 89% remaining, are beginning to squeak, which your team claims is normal. This assessment is difficult to accept.

After pulling my 2024 GMC Sierra 1500 SLT into a parking space at a local store, I shut off the engine. I observed the lighted ignition switch and the dash icons were illuminated even though the engine was completely off. Having had my foot on the brake at the time I decided to test the ignition switch to determine why it was lit while the engine was off. When I pressed the start button there was a loud, whining starter like sound, grinding like metal on metal. The noise was so alarming that I immediately took my hand off the ignition. The engine was still off. After waiting a significant amount of time I tried to restart the engine. Exactly the same thing occurred. On the final attempt to start the engine, 15-20 minutes later, it started and ran quietly like nothing had ever happened. On returning to the vehicle my wife asked what all the loud grinding noise was about. She had heard it while she was inside the store. I advised her it was our truck! The incident was shocking to us both and because of its bizarre nature I was afraid to drive the vehicle back home. As I already had an appointment on November 6 at DeLuz Chevy for another incident, I called them on November 3 to add this incident to the existing appointment. This incident was added to the November 6 appointment. Unfortunately the service department did not assess the previous incident and only addressed this incident.

GM is recommending that I replace my brakes for the 3rd time within 30,000 miles but cannot explain the irregular wear. I am confident that there is a larger issue causing this is the brakes failing are just a symptom of a larger issue that have failed to address after 6 dealership visits, escalating (twice - due to first advisor never getting back to me) to GM customer care, emailing an executive, regional service manager, and countless hours to fix the safety issue of my brakes (and the larger root cause issue). GM Customer Care Case #[XXX] - BRAKE SAFETY ISSUE 2024 GMC Sierra AT4 (VIN: [XXX]) - 46,000 miles Nov 2023: 1st visit - Brake squeal at 25K. Pads replaced, GM denied warranty. Early 2024: SAFETY ISSUE RETURNED at 30K miles. May 2025: 2nd visit - Worsening brake noise. Dealer couldn't replicate despite video evidence. Recommended $500 repair. Manager acknowledged "irregular/abnormal" wear. June 2025: 3rd & 4th visits - Tech found unexplained "weird line" on pad. Manager Kyle confirmed unusual wear but no root cause identified. June 10: Opened GM case #[XXX] after dealership failures. July 7: GM failed to coordinate promised appointment. July 14: 5th visit - Les Stanford Buick GMC, Ferndale. Tech rode with me, CONFIRMED BRAKE SAFETY ISSUE but offered no solution. CRITICAL SAFETY CONCERN: Recurring brake defect with abnormal wear patterns acknowledged by multiple technicians. Same brake failure pattern occurring 3 times in 18 months poses serious safety risk. Despite 5 dealership visits, video evidence, and confirmed defect, GM refuses warranty coverage while acknowledging the problem exists. Issue remains unresolved - I've exhausted all customer remedies. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On the morning of March 12, 2025, I started experiencing a ticking sound from the engine bay under throttle. I suspected lifter failure and decided to proceed to the dealership that afternoon for repairs. During my commute, the engine started squealing and shuddering and I experienced a severe loss of acceleration which made it almost unsafe to drive on the highway. Upon coming to a stop in traffic, the engine died. I was able to get it restarted and proceeded to continue my trek to the dealership. Upon another traffic stop, the engine died again, at which point I made the decision to exit the highway and continue my journey along the service road. Twice more the engine died when coming to a stop and the 4th time it struggled to restart. I finally decided to pull into a parking lot and as I was backing into a parking space, the engine died its final time and would not crank/turn over. To make matters more difficult, the transmission would not even shift out of "PARK" into "NEUTRAL" for it to be laoded onto a tow truck. Each time I tried to shift out of "PARK" I received a message stating "Conditions for shift not met"
