The vehicle has experienced persistent engine performance issues that have not been resolved through standard repairs. Initial diagnostics indicated knock sensor faults, which were replaced at significant cost. However, the issue persisted and additional codes related to air fuel imbalance (P219B) appeared. The vehicle continues to exhibit reduced power, hesitation, and inconsistent acceleration while driving. This creates a safety concern, particularly when merging into traffic or attempting to accelerate in situations requiring reliable engine response. The dealership has quoted a minimum repair cost exceeding $7,000, with the possibility of increasing to $10,000 depending on further findings once the engine is opened. Due to the high cost and uncertainty of repair, the vehicle may remain in operation with an unresolved defect. Research indicates that similar issues have been reported by other owners of this vehicle generation, suggesting a potential broader defect that may impact vehicle safety. This issue affects the vehicle’s ability to deliver consistent power and safe acceleration. Given the relatively low mileage and the severity of the repair required, this may represent a defect that warrants further investigation.

When driving all gauges go to zero, truck doesn’t illuminate which gear it’s in, warning lights come on (service 4WD, service stabilitrak, service traction control, reduced power steering, service traction control, service trailer brake system ). When NOT driving if these issues show on the dash when parked and the car doesn’t illuminate which gear it’s in, it does not crank over, does not start, there is no clicking noise either like if it was a bad starter. All the dash lights, gauges, radio goes black as if I turn the vehicle off instead of on. This has been happening since around 2020-2021 in Colorado. It was in a shop for over a month with no resolution. In Idaho in 2022-2024 in a shop for a month with no resolution, and now CA in 2025. No mechanic shop can figure out what is wrong, no “certified GM” shop or “certified GM engineer/technician can tell me what’s wrong. I have had the following replaced already and still having issues. Body Control Module (BCM), the Transfer Case control Module (TCCM), and the Brake Control Module (BCM).

While driving my vehicle, with around 85,000 miles, the engine suddenly began running rough and felt jerky and sluggish. This was concerning and potentially dangerous situation, as the engine failure happened while I was travelling at high speed. A sudden loss of power on the highway put me and other drivers at serious risk. The check engine light came on, so I pulled over as soon as I could safely do so. Shortly after, the light started flashing, so I shut off the engine and contacted the dealership service department. They advised having the vehicle towed in for inspection. Prior to this event, I had not had any issues with the vehicle nor had the check engine light come on. After looking into it, the dealership initially suspected a thrown rod but said they wouldn't know the full extent of the issue until they could tear down the engine. Upon further inspection, they determined that the lifters had failed and would need to be replaced. The dealership has performed all regular maintenance and oil changes on my vehicle. When I asked what could have caused this, they explained that it's a known issue with these lifters and engines - one that Chevrolet has experienced for years, even in models prior to my 2017.

Electronics for hands free stopped working. This part was already replaced once. When backing up, the whole truck shut down. I restarted, it said to roll drivers side window down and up. Truck started up again. Few days later... returning from trip, lost power, windshield wipers came on, electronics in truck started blinking. Pulled over, rolled driver's side window up and down. started back on road. This has happened numerous times. Whenever I gave it extra gas, asking for power to pass, same thing mentioned above happened. Very stressful! Next day, hit a hole, truck totally shut down again. Husband was able to safely coast off road, however, if he had been pulling out at a major intersection, this could have been bad. Warning light that comes with shutdown says "stabltrack issue". I have not seen our dealer service department yet, but plan to very soon. VERY unsafe... and I love this truck!!!!

My truck is a 2017, but only has 46,000 miles on it. The engine light came on and it started banding loudly. I lost power and it would not go over 30 miles per hour. The dealer informed me the lifter failed and destroyed the cam shaft. Upon research, I have discovered this is a problem for many of the 5.3 engines. Many people are stuck now. I realize I have no warrantee, but I take excellent care of the truck and it only has 46,000 miles on it. It should not need a new motor, especially if it is due to a defect from GM. They knew about this issue and are doing nothing. I am now faced with an $11,000 quote for a new engine. This is wrong on so many levels.

The truck suddenly started misfiring, running rough and lost power while driving. All the dash lights illuminated and the check engine light began flashing. We were a couple hours from home so we had to have the truck towed home. This could have been much worse as we were towing a trailer on a busy highway but luckily we were able to pull over to the side of the highway. Upon returning home we had the truck checked at the local Chevrolet dealership service department and were told we needed a whole new engine. After about 5 months after the initial incident we paid to have a new engine installed at the same dealership that inspected it. The truck had not exhibited any signs of any problems prior to the incident.
