2022 GMC Sierra 1500 Problems and Top Complaints – Is Your Car A Lemon?

Electrical system & engine issues are among the top complaints received by the NHTSA from vehicle owners

The 2022 GMC Sierra 1500 is a truck meant for getting jobs done. The automaker claims it also contains “next-level technology.” However, customers are quick to complain about the glitchy electrical system, a defective engine and terrible service brakes.

Problems with the Electrical System

With the newest technologies, there’s nothing holding a vehicle back. However, the bad electrical system in the Sierra 1500 is only keeping it from succeeding.

One NHTSA complaint says, “Check engine light came on at 458 miles. Took it in and after an hour they determined it was the ECM. They said it was bad. Now they’re on the hunt for one. In the meantime, in a day the truck has started feeling like it’s over shifting and then bogging down. 458 miles, really! I’m going to need a loaner for longer than I’ve had it and still make payments.”

Of course, there are more problems than can be counted quickly. Even Service Bulletin #21-NA-166 discusses how the turn signal stalk isn’t canceling or it’s canceling when it shouldn’t. It probably looks funny to be behind the Sierra with a crazy turn signal. It looks like it can’t make up its mind whether it should be on or off. Otherwise, it could just be grandma driving.

Problems with the Engine

The engine in a truck is essential for providing reliable power, but this motor is a disgrace to the pickup lineup.

Another NHTSA complaint says, “Purchased 2022 GMC Sierra on 1/18/2022 with 0 miles on it…On 04/08/2022 the engine started a loud knocking noise…sounded like a piston trying to shoot out of engine. Very loud. I was afraid to drive it. We took it to the dealership and they said they have had a few come back for lifter problems. Not very happy for my purchase of a brand new truck with 0 miles on it after driving for less than 3 months.”

If this wasn’t enough, take a look at Service Bulletin #PIP5844. It states that DTC P06DD gets set because there’s no oil pressure following an oil and filter change. It’s something that happens because the filter was drained and empty. However, the filter is always drained and empty for a second after an oil change. This shouldn’t lead to trouble codes setting unless it’s a defective system, which is what the Sierra 1500 is.

Problems with the Brakes

The “next-level technology” should carry over to the service brakes, but this is just one more system with major trouble.

One final NHTSA complaint says, “The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving approximately 70 MPH, the “Service Vehicle” warning light displayed. Additionally, while depressing the brake pedal, the brake pedal extended to the floor however, the vehicle failed to respond or decelerate. The contact stated that the ESC, trailer brake, and brakes warning lights then illuminated. After stopping the vehicle, the contact restarted the vehicle however, the warning lights remained illuminated. The vehicle was then towed to the local dealer who replaced the brake master cylinder and ABS module. The manufacturer was notified of the failure. The VIN was not available. The failure mileage was 9,700.”

With this problem, GMC chose not to issue a service bulletin. In fact, from the automaker’s standpoint, there seem to be no problems with the brakes besides there being more than 100 other manufacturer communications. It seems a little strange that the automaker is so willing to discuss other defects but nothing that has to do with the braking system.
