general problems of the 2022 GMC Sierra 1500

The forward-facing camera module and related advanced driver assistance systems (adas), including adaptive cruise control and lane keep assist. The system has failed repeatedly, with the camera replaced three previous times. On xxx, the vehicle performed unintended hard braking at approximately 70 mph on the interstate, after which adaptive cruise control and lane keep assist became inoperative. Similar hard-braking events followed by system failure also occurred approximately one month prior to the most recent previous failure. The dealership (confidence Chevrolet Buick GMC in [xxx]) has confirmed the forward-facing camera and adas failures on multiple occasions. The camera module has been replaced three times (xxx). During the xxx repair, technicians documented diagnostic trouble code u3000:49 (internal malfunction in the front view camera module), opened tac case xxx, and performed radio programming per bulletin 25-na-318. The dealer has repeatedly verified the loss of adaptive cruise control and lane keep assist. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Current unsafe conditions: post-replacement active safety failures. The vehicle presently exhibits two distinct categories of active, ongoing, and dangerous safety failures, both of which were introduced as a direct result of the engine replacement performed by monument Chevrolet: (a) severe drivability failure. Between approximately 1,500 and 5,000 rpm, the engine repeatedly and without warning lunges forward, drops all power, and lunges again — cycling in this manner between three (3) and six (6) times before stabilizing. This behavior occurs across all gears and driving conditions, which creates a severe and unpredictable hazard particularly when merging into traffic or accelerating onto highways. This failure constitutes an immediate and ongoing risk to the safety of myself and other motorists. (b) complete adas system failure. The frontal crash response warning light is permanently illuminated on the instrument cluster, rendering the following federally relevant safety systems entirely non-functional: (I) automatic emergency braking / forward collision alert; (ii) cruise control; and (iii) lane change assist / lane control system. All of these systems were fully operational and properly functioning before the vehicle was submitted for the engine swap. Their failure is an assembly defect introduced by monument Chevrolet during the course of the repair and constitutes a warranty and safety defect for which general motors, as the manufacturer and warrantor, bears full responsibility. Medical hardship and urgency. This vehicle is my sole personal transportation. It is essential for travel to active medical appointments and upcoming medical procedures. The ongoing failure of general motors and its authorized service network to restore this vehicle to a safe and fully operable condition has created a serious hardship that directly affects my ability to access needed medical care. Yes, it was driven by a service department supervisor. He did experience the issues.

I was driving to work on 7/20/26 and my vehicle loss engine propulsion , engine failure and unable to restart vehicle and shift gears.

While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a p1098 code. After researching I found out it was the engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

The front forward-facing camera module has failed, causing cruise control and driver-assistance features to become inoperative. Dealer diagnosis indicates the front camera must be replaced and recalibrated in order to restore cruise control and safety systems. This failure disables cruise control and driver-assist features that were standard equipment on the vehicle at purchase, resulting in a sudden loss of functionality while driving. The dealer has provided a repair estimate of approximately $1,150, including parts, labor, and required calibration, at owner expense. Based on similar reports from other owners, this appears to be a recurring issue affecting this model year.

P2101 reduced engine power idle instabilitystruggling to idle correctly, hunting/surging slightly, and possibly going into reduced-power protection mode. While driving engine reducing power, struggles then surges forward. Ive taken it to GMC however the techs say they have to experience the situation themselves and are unable to diagnose.

Service trailer brake system, service esc, steering assist is reduced, brake system failure. Almost had an accident because of the brake system failure.
