NHTSA Complaint #11656204 — 2023 CHEVROLET SILVERADO 1500

At 383 miles the engine started a ticking noise. Around the same mileage the transmission would also start make hard down shifts, especially into 1st gear. At around 27000 miles transmission would also shutter at light loads and low speeds. Attempted to take it to dealer 2 different times, but they had no loaner cars and needed it for more than a day. At milage 28,251 I drove to the dealership an insisted that it needed to be fixed. They were able to provide loaner car at that time. Engine ticking noise was cylinder number 7 lifter stuck closed. Transmission was unable to be checked due to engine needing repair. The Dealer replace all 8 lifters on drivers side of engine. Upon the fix they test drove for the transmission problem and noticed noise coming from the water pump. Replaced the water pump and was told transmission needed a new valve body. Those parts were on back order for over 3 months. They found a service bulletin to reprogram the transmission so they could release the truck to me instead of hold months for parts. After more than 30 days in shop picked up truck. After driving around for a few hours noticed engine noise again but different. Like a bearing? Dealer had already closed so took it back the next day. Couple days later was informed that the head gasket was installed wrong? REALLY. Went to the dealer's new car manager and asked to be traded out of it and into a new truck. Dealer offered me 10,000 below blue book for trade in! They didn't even want their own product back. Picked up truck couple days later and drove straight to Toyota and traded it in I needed a reliable truck. The dealer's service department was great with the problem. But it's the product that really [XXX] and had the potential to be very dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
