2022 CHEVROLET SUBURBAN Electrical System Problems

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.

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...

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.

Driving down to Florida, No warning, no lights, never any issues except a belt replacement. I get oil changes, tire rotation every 3500 miles. Almost got killed doing 75 miles per hour, engine sputtered, totally shut down. Coasted onto an exit ramp thank God it was right there or we could of been killed. Tow truck towed to Davis Chevy Gainsville, they called me on Monday said good news I have a warranty bad news Total Engine Failure, will take 3-4 weeks to replace. Now I am trying to find a GM rental large enough to get me and my family back to TN since GM said they will only pay for a GM rental car. Scary, could of gotten killed. NO NOTICE FROM GM ABOUT ANY POSSIBE PROBLEMS....WE ALMOST GOT KILLED AND CRASHED along with the other drivers on the road. Thank God it was a Sunday and 6...

While driving on vacation our car just slowed down gave the message, “reduced acceleration, drive with care” and then shut off while on the high way. We were able to start it again but after that haven’t had that message but have had the message to service safety restraint system multiple times. I have taken my SUV to the dealership multiple times for both issues and they have said multiple codes generate but they can’t find anything to fix.

While driving on the highway at 55 mph during a long-distance trip, the engine of my 2022 Chevrolet Suburban (6.2L V8) failed suddenly without any warning lights, messages, or prior symptoms. The vehicle lost power unexpectedly, creating an extremely dangerous situation. I was traveling to a national wheelchair basketball tournament and had a passenger in the vehicle at the time. Our safety was immediately at risk due to the abrupt loss of power in a high-speed traffic environment. The vehicle was towed to the dealership, where the issue was confirmed as a complete engine failure. The dealership later replaced the engine under warranty. I was informed that the engine installed was the same model currently under active recall (N252494001), which affects the 6.2L V8 engine in this vehicle type due to defective crankshaft or connecting rod components. The failed engine is no longer available for inspection, but the dealership should...

While traveling back from Labor Day Weekend on [XXX], I was driving in the Dallas Fort Worth area when I experienced loss of power to our vehicle on a major highway [XXX] and [XXX] ) and directly on a bridge with my entire family in the vehicle (4 kids and all of our luggage). It was a very dangerous and scary situation. We had to wait one hour for a tow truck to come and take my vehicle to the closest GM dealership. I was left stranded, 3 hours from my home with my four children and luggage. The Chevrolet dealership contacted me 9 days later and informed me the technician looked at the vehicle and determined the engine was locked up/seized. It would take 9 months to get the vehicle back into the shop to determine what caused the issue and then take 6-12 months for a new engine....

The 2022 Suburban lost all power and came to a dead stop in the travel lane of a busy major highway. The vehicle becoming disabled in the middle of flowing travel resulted in a rear end crash from a vehicle traveling approximately 60 MPH.

- Truck makes a sizzling sound when parked - Car wouldnt start and needed battery jump, unknown source draining the battery - Truck has engine issues , started shaking and died in the middle of the highway, GM replaced engine - Engine replaced after less than a week, truck would not start, Gm replaced starter - After 2 days and using the vehicle once, truck would not start again. GM is trying to root cause issue but cant find a resolution Since the car stopped when we were on the highway and none of the fixes seem to be working I am worried that the car will abruptly stop again and put my life and others at risk

The contact owns a 2022 Chevrolet Suburban. The contact stated that while his wife was driving at an undisclosed speed, the vehicle stalled. The message to restart the vehicle was displayed. The contact stated that the failure had occurred while the Auto START/STOP feature was enabled and disabled. The failure forced the contact's wife to shift into park or neutral before the vehicle would restart. The failure occurred several times while the contact's wife was driving the vehicle several times and stopping at the red light when the vehicle stalled. The contact stated that the vehicle had been taken to a dealer previously and the failure was not duplicated. The contact stated that the failure occurred intermittently. The vehicle was taken to a second dealer, but the failure could not be duplicated. The vehicle was not repaired. The contact was informed that unless the failure was recognized, the vehicle could...

The car turned itself off while driving 55 to 60 mph on a highway. Would not turn back on after getting to the side of the road. Very dangerous.

It was diagnosed as the Telecommunication Module, this part malfunctioned causing issues with audio in the vehicle. The audio would at times play normal, at times go completely out losing all sound to turn signals, hazard signals, and safety sensor audios inside the vehicle. It would additionally lose communication between the key fob and the unit causing warnings during driving and non-start issues. With that said, the lose of audio when expecting safety sensor sounds, or sudden audio on complete full volume with the only resolution being to shut the car off is a safety issue. The vehicle had to be pulled over on the travel portion of the highway to resolve the sound issues on multiple occasions. Software updates, radio head change didn’t matter, until it was diagnosed as the module described above. Occurrences were completely random.

When I started up the vehicle with the key fab button I noticed the cabin air blower came on as normal however when we went to the cockpit we noticed the engine was not running. When we went to start the vehicle (holding break and pressing start button) the dashboard started the Z71 launch sequence and then went to a dashboard as if I was in the normal drive mode however the dashboard was extremely dimly lit as if the backlight was not on and the engine still was not running. After several attempts to start using the brake+start button method we noticed a clicking sound that seemed to be coming from the engine cabin just in front of the passenger cabin however it would never ignite/start the engine. After several attempts to start the engine through the brake+button, we tried to just press the start button, which would sometimes...
