Car initially started stuttering on the high, check engine and traction control lights came on. I immediately went to the nearest Chevy dealership a mile away. Initially I had 20 error codes. The problem was the Left side lifters 4 of 8 stop working. Dealership recommended Replace Left lifters, 2 push rods, valve cove, head gasket. $5000. After starting the work. The technician could not repair the lifters because my camshaft is pitted and the RODS were rotating. Their recommendation is to replaced the whole engine to fully fix the problem. $12000 with 3 yr warranty. My SUV just 100kmiles.

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.

Engine failed while driving. Vehicle began making clicking noise less than one minute for engine shut off while driving. Check engine light came on after engine shut off. Car was stopped at a busy intersection and couldn’t move. Car is currently at Chevrolet dealership and is in need of a total engine replacement

The contact owned a 2022 Chevrolet Suburban. The contact stated that while the vehicle was parked with the engine running, the front of the vehicle began to shake violently, with a knocking sound coming from the engine compartment. The check engine, traction control, and collision warning lights were illuminated. The contact called an independent mechanic; however, the vehicle was not diagnosed or repaired. The contact later visited the dealer and was informed that the vehicle needed to be brought in for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 97,000.

Hi my 2022 chevroley suburban has been sidelined for more than two months with a problem that involves my cylinder number 5 ( lifter and camshaft or crankshaft ) i believe. a well known issue with these cars. i happened just a few miles out of my warranty. when i went to chevrolet to explain to them. they didn't want to fix it. i have two young children that i take to school with this vehicle and they won't help me. this is a known issue with this model and it has been recalled many times. i'm stranded because of this car being out of an engine ... mind you the problem started well before my warranty and i was thinking that i needed some spark plugs ... by the time i realized it ... it went right over my warranty.

I own a 2022 Chevrolet suburban and bought the 72k mile extended warranty. Recently my telematics module went bad which is covered by the GMPP. I lost wifi, my clock is wrong everytime etc. However General Motors no longer makes this part anymore. Parts department utilizes a third party company called specmo for a refurbished authorized unit. However, GMPP will only cover the original msrp not the inflated price from the company specmo that GM uses for these parts. This part is 100% covered based on an msrp for a part that they no longer use and states that policy does not allow them to cover the full cost over the original msrp of the part. This is an issue that is all over the forums and internet and is ridiculous that GMPP is an extension/better than manufactures warranty yet they will not fully cover the full cost of the part that is covered. A few days later I was driving and my abs, traction control, steering, brakes, everything was flashing and not responsive or dramatically reduced like my brakes where I could not stop immediately with me and my 5 kids in the car.

Summary: Sudden loss of engine power while driving due to lifter failure. Details: While driving my 2022 Chevrolet Suburban equipped with the 5.3L V8 (RPO L84), the engine suddenly lost power without warning. The vehicle began misfiring and lost propulsion in traffic, creating a hazardous situation. I was unable to maintain normal speed and had to maneuver to safety while the truck rapidly lost power. The dealer later diagnosed the problem as a collapsed lifter/valvetrain failure — an issue that GM has already documented in service bulletins (PIP5776G, 23-NA-043) and a service update (N212353840). These bulletins show GM has long been aware of defective lifters in 5.3L engines. This is not just a drivability concern. A sudden engine failure and loss of propulsion while driving poses a clear safety risk, especially when merging, crossing intersections, or towing. I maintained the vehicle properly and have all service records. I request NHTSA investigate these widespread lifter failures in GM’s 5.3L V8 engines as a safety defect, since they can and do cause sudden loss of power in motion.

Onstar module failed, no longer have wifi, navigation or other onstar supported features. Cannot perform system updates for vehicle due to onstar module. Cannot use app due to onstar module.
