“This is a follow up to my recent safety concern on my 2025 GMC Sierra 1500 with the 6.2 engine. Dropped off my vehicle to our GMC service dealer on 10/22/2026 - Oil change and 15K mile check up was getting close. Mileage at drop off was 14,278 and the engine was still making sounds/noise and getting louder. Asked the service advisor to check for metal in the oil or filter. Based on their service review and advisors response, metal was found in the oil filter and engine is ticking. Service department sent information to GM rep for further actions needed. Dealer rep stated that I need a new engine due to this new found issue. Waiting for response from a GM representative at this time. Truck is in my garage at home. I remain very concerned about driving this vehicle at this time. Just called the dealership as I have not heard of any follow up yet. Call went to voice mail of my service advisor. 6.2 Engine is ticking and metal has been found in the filter. Please add this to my original concern on this VIN #.”
“The engine locked up and stalled out while driving. GM replaced engine but still experiencing issues. Dealer has admitted that they will likely recall my model year since it is an ongoing and same issues as recalled trucks. I have a vehicle I am not confident in nor safe it since it stalled while driving.”
“Repeated failures on my 2025 GMC Sierra EV. The truck shows 'Service High Voltage Battery' and the high voltage battery makes a high-pitched hissing noise; it has thrown battery errors twice. The A/C has failed repeatedly; this summer a passenger in the truck overheated and suffered heat stroke because the A/C was not working. Super Cruise and other driver safety features consistently fail while driving. The GPS/telematics module has failed (GPS never finds a location). The truck was at Bob Howard GMC in Edmond, OK from [XXX] to [XXX] (repair order [XXX], 41 days) for the telematics module and A/C, and went back on [XXX] for the A/C and battery and is still in the shop. GM case number [XXX]. No crashes.”
