2022 Chevrolet Suburban electrical problems

Filed Sep 2, 2026 · Electrical, Engine · TX

This problem isn’t just the 6.2L engine. My 22 Suburban has the 5.3L and had engine failure on the freeway going 70 mph in April 2026. Loud noises and loss of power. Towed to dealership and was confirmed that it was the same issues as the 6.2L. The dealership only replaced certain components (gears, rods, camshaft etc.) Parts replaced and vehicle returned a month later but still loss of power and bad idle. New dealership in May 2026, replaced same parts, said faulty parts were used at previous dealership. Vehicle repaired and returned in June2026, a day later new code for service transmission now code thrown and parking break not working. Returned to dealership and said it was a fuel pump module? failed. No vehicle for 3 months and lots of headaches. This recall needs to be extended to the 5.3L engine as well. Needs full replacement, not just repaired. My vehicle still doesn’t run great but Chevy will not honor anymore repairs.

Operating vehicle normally until one day I heard a rattling noise from the engine compartment. Car had limited speed and i had to pull over to check what the issue was and the car wont start. No check engine lights, no warning. Tried turning car on but only the car starter keeps rolling. Tried jumping and it doesnt start and had to have it towed to the dealership. Car is under 55,000miles and dealer diagnosis indicates there are metal particles in the new oil after replacing oil and a loose bearing. States i will need a new engine, which is on back order and GM will only cover $44/day until repair is complete. All maintenance and oil change invervals were kept up to date. Other days when I start the car, the main HUD with the speedometer does not turn on. Pitch black... I can drive but not know what my speed is. I had to disconnect battery and reconnect to clear the issue. It has happened several times.

In several separate unreplicable instances, the vehicle has turned off while driving, once on the highway, once on my street, once turning across heavy traffic, and others. I've almost died a couple times and I've taken it to the dealership several times, they have Not been able to find anything wrong with it and have been unable to replicate the issue. The engine has been replaced, and it was happening before and since. My 2023 is also doing the same thing.

Vehicle accelerated while driving. The RPMs gage turned red; however, the vehicle stopped in the middle of the road with other cars coming. After the vehicle came to a full stop it would not move. Finally it started moving slowly and I was able to get off the road. When the tow truck arrived the vehicle would only go forward. No reverse. Error message on dashboard picture attached

Onstar, my vehicle's core safety communication system, stopped working without notice, without an alert on the dash. Nothing. I press the onstar button and nothing happens. What if I was in trouble? Didn't have my phone? The issue was not communicated to me through the infotainment system. This seems like a serious issue.
