I purchased my vehicle in 2019. Since then, I have had several issues. I've had to replace the coolant reservoir, DEF heater/pump and twice changed the number 8 injector plug. The warning light came on just after the warranty went out. The code reader read the ambient sensor and no sensor.

The other day approximately 5 minutes after leaving my house I noticed a smell and saw some slight smoke coming from my rear window. I immediately turned off the rear defrost and my rear window shattered. The next day I discovered other Chevy/gmc vehicles have a recall for a short circuit in the rear defrost. Unfortunately the dealership will not help me until there is a recall with my vin as there is not an open recall on my vehicle.

Bought the vehicle new in 2019 currently at a dealership to have the third in tank electric fuel pump installed. When it was in the shop for the second fuel pump installation the technician informed me that the pump can go out at any time causing a potential accident. Fortunately truck wouldn’t start and was diagnosed at dealership.

Service brake brake system comes on randomly. have to hit reset when driving. constantly

The trailer brake system has stopped working and displays the message "Service trailer Brakes" it does this no matter if several different tralers are hooked to the truck. These trialers test fine in other trucks and with meters. The trailer brake controller does not work. There are many owners reporting the same thing. It is a critical safety feature to stop the truck & trailer and probably already has led to some fatalities. Please issue a recall. Thank You.

Intermittent issue with entire dash lights and radio lights going either fully out/off or extremely dark. Adjusting dimmer does not correct the issue. Affects driver safety due to acute driver distraction while trying to correct, and disables driver warning lights and all information systems, including towing related warnings (transmission temp/coolant temp, etc) Dealer advises to bring it back when it is occurring, but occurrences are not predictable, nor do they occur on a regular basis. Cause is unknown, but since dimmer switch does not correct this issue, it is the probable cause.

While towing our trailer, truck went into reduced power mode, regen message displayed; check engine light came on; loud bag occurred and hissing from under the hood. Truck slowed to 3 mph so we pulled to shoulder and turned the vehicle off. Truck had blown the hose off the the turbo. We reclamped and restarted. Displayed check engine light, reduced power & regen message to keep driving however truck wouldn’t go over a 3mph crawl. Truck lost all power, everything shut down and wouldn’t restart. No dash lights, no error, no crank, no power. We were dead on the highway in the truck lane while towing. This Truck goes into reduced power mode every time it tries to regen and we have had it to the dealer multiple times however, the problem continues to get worse. When it does regen, sometimes it takes hours. Dealer says needed a manual regen & that is their solution. Yet problem persists.
