I was driving our 2021 Chevy Suburban, which had ~107,000 miles on it, at approximately 75 miles per hour. With no other indication, the low oil pressure light came on, then within two seconds I lost all power (motor shut off) and lost electronics in the car. I had to man-handle the vehicle to get it off the road without power or dash controls. Our family was stranded near the California/Nevada border with no cell reception in the middle of the night for over seven hours. I spent a fortune having the vehicle towed to a Chevy dealership (Wild West Chevrolet in Yerington, NV) where they indicated that there was a main bearing failure which caused the engine to seize. A full L87 motor replacement is required. The motor is currently on backorder with GM due to the high number of L87 engine failures. GM has not provided an estimated date of when they plan to have the motor replaced.

Service safety restraint constantly reappears. Taken into dealership 3 times and still has not been fixed. This could cause serious injury or harm and I have 4 children 10 and younger. This has been an on going problem.

A warning message appeared on my 2021 Chevy Suburban dashboard that says "Service Safety Restraint System". This impacts the airbag control module under the driver seat. After doing some research on my own this is a TSB PIT5759 but it is not covered under a recall, as per my local dealership. I took the vehicle to the Chevy dealership where purchased and was told this is not a recall or warranty part. This is very disappointing as it impacts the airbag controls which in an accident could cause severe injury or death.

Seat, mirror, steering column pre-set driver adjustments do not come into proper driving configuration on a regular basis when starting vehicle. This is a dangerous situation when a malfunction does occur. Seat has tendency to squeeze driver torso into steering column and knees into dash. LH mirror inadvertently and unexpectedly tilts down toward the ground and ofter unnoticed. This makes for a dangerous condition where the driver assumes that there is no oncoming rear traffic and it's safe to pull away from a curb from a stopped position. This condition has occurred for over a year and while the vehicle was covered under factory warranty. Numerous trips to Bonner Chevrolet in Kingston service department for remedy have yielded nothing. Bonner Chevrolet walked away from this serious issue and told us there's nothing more they can do and said, sorry. In contact with Chevrolet through Chat messaging, the recommend other surrounding dealers. None are interested at this point. the chat messaging is as useless as Bonner Chevrolet. Meanwhile I'm driving and paying for a useless and dangerous vehicle which no one knows how to repair. This has been an ongoing event since June, 2023.

Multiple issues with transmission since owned. It randomly goes into "limp" mode and everything will blink and it won't start back. The transmission has always shifted hard and sounded funny they told me if was normal for the vehicle. Leaking transmission fluid when owned for 4 months. I have had to the dealer multiple times, several repairs, told it is safe to keep driving by GM. The inverter is bad and told me it was ok to drive until they can repair. GM will not give me a fair response or answer. The dealership won't buyback, and offered to purchase for nearly 30k less than I bought it for 18 months ago brand new. The engine light comes on and off randomly told me it was ok with a diesel it may do that when it gets cold.

Car suddenly swerved, loud knocking started. Multiple system failures started flashing. Forward collision, ECS, traction control, the car was vibrating, jerky. I have multiple videos as well. The dealership literally told me they-??d seen a ton of these when I called immediately and then told me to keep driving because the damage was done and if the engine died well then it-??s under warranty. I have 3 children under 5 and that is NOT an appropriate answer when I asked about it being safe to drive considering it-??s jerky/shaking/knocking, and has multiple systems down. I-??ve also googled and joined forums and this is apparently a common issue in the 2021 V8s and Chevy refuses to issue a recall. Would be more than happy to provide videos as well it won-??t let me upload them with the photos. Was told it could be weeks before they even have parts

We have had several incidents of issues with the engine and electrical system. There are as follows: - NO CHECK ENGINE LIGHTS and engine failed. - Engine continues to be sluggish and hesitant. Headlights do not come on when in "auto" and it is dark outside. - Doors lock with the keys inside and the engine is off. - Keys are showing in sleep mode or not present when they are present. The engine went down on May 6, 2021 and I was on the highway with 2 of my children. I could not accelerate. There was traffic and could not keep up. I was able to get the truck to the delearship to have inspected and repair attempted. NO check engine lights.

This evening while driving the windshield wipers started (while the wipers were in the off position). When using the turning signal it speeds up to approximately 3 times the normal speed. The display says the back hatch is open and the cargo light is on (the back hatch is closed). We turned off the car multiple times and the conditions persist.
