Warnings problems of the 2022 GMC Sierra 1500

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.

1 month after warranty was up the dash light came on. After researching and speaking with the dealers. Pull the f11 fuse then try un hooking the negative battery terminal. This worked for a few weeks. Then told it could be a software issue. I spent many hours search the internet only to find out there are thousands of trucks dealing with the same issue. Why is there a recall on a grill and not this issue? lots of very unhappy GMC truck owners!!!.

For the past 6 months I’ve had issues with my crash avoidance system, steer assist and lane departure warning. The crash indicator light would illuminate on my dash for no apparent reason. That would disable my crash warning system, steer assist and lane departure warning but, I could still adjust my distance for my brake warning indicator. The other problems that are not safety related is cruise control and automatic high beam lights will not function. I researched the internet and found this is not an uncommon problem for this year model. The most common fix (if the windshield is not dirty) was remove the f 11 fuse, in the fuse panel beside passenger door for 10 seconds, that would allow the system to reboot. That worked for 3 months with more than 10 occurrences of the light illuminating on the dash. Now the crash indicator light is on continuously and will not reset by removing the fuse. The computer is up-to-date and all the settings in the infotainment system for the crash avoidance system are activated. Check numerous internet websites, the cameras for this system is on backorder. So there must be a parent problem with the system. I was required to purchase 36 months of onstar, I did not purchase a renewal agreement after the 36 month and this issue started soon after.

Intermittent failure of audio and safety alerts (forward collision alert, lane departure warning) dealership’s response: “no fix” despite warranty. Safety impact: increased collision risk.

I bought a new GMC, I received 3 vouchers for computer chips to be installed at a later time years ago. They have not provided them. They are selling new fully equipped vehicles with computers chips just fine. Can you handle and have GMC install their backlog of computer chips? there are many safety features that do not work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal. Thanks.

The back-up/reverse cameras black out mid action and also once the vehicle is put in reverse. During inclement weather conditions, a car stopped abruptly in front of me to avoid a huge pool of water on the highway and the forward collision braking system did not kick in and now the light is illuminated on the dash board and won't turn off.

The forward collision assist and lane keep assist are suddenly not working. This seems to be a software or eletrical issue.

Truck has the safety package on some point stop working bring the truck to the dealer but they don’t know how to figure out I need help with this.
