ENGINE
Engine while driving completely seized up. Crank shaft, cam shaft and oil pump water pump replaced. Low oil pressure alarm code present then sudden loss of power. Piston blown. There are similar recalls to 2021 suburbans however, this specific model is not in the recall. I was told I need a completely new engine. The car died in the middle of traffic and police had to call an emergency tow truck.

ENGINE
Cause unknown, however, I have discovered that the engine in my Suburban, the Engine code LZO 3.0L Duramax, has damaged itself internally. I have been told that there is a large batch of engines that have this same problem, and the dealership I sent my car to has several cars in the same position. This problem is causing the engine to lock up or completely quit. This could be serious depending on when this failure happens. Currently, they are telling me that I am months away from getting a new engine due to a back order. Vehicle still in shop, so I do not have records yet, but I will be happy to give them once I have them.

SEAT BELTS
The passenger seat belt will no longer just click in. In order for us to get it to latch, you have to push down on the red button as your pushing the seat belt in, then it will latch. We bought this used and within 1-2 weeks this happened. But other things happened with the engine and that took priority. It was in the shop for almost 6 months. I'm not sure if the dealer/ previous seller knew about it and they were able to "fix" it so it worked when we bought it. (We are lied to on a lot of things) I'm afraid that it might not hold up in a crash if it's not buckling right.

ELECTRICAL SYSTEM, ENGINE
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.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
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.

ENGINE
I own a 2022 Chevrolet Suburban (VIN: [XXX] ) that is included in NHTSA Recall No. 25V274 / GM Recall No. N252494000 for engine defects in the 6.2L L87 V8 engine. My vehicle was inspected at an authorized GM dealer today, on 9/23/2025 (Don K in Whitefish Montana). Instead of replacing the engine, the dealer performed the recall “remedy” of switching to higher-viscosity oil, changing the oil cap and filter, and providing an owner’s manual insert. However, the dealer service manager specifically told me that my engine will eventually fail due to the known defect and advised me not to drive the vehicle on long trips. He also told me to be careful driving if I have children, and it is only a matter of time before the engine fails, which will look like sudden shuttering, loss of acceleration and it will no longer run. He told me wait time to get a new engine after it fails is currently 8 months. This is alarming because the recall notice states that engine failure can cause sudden loss of propulsion without warning, which could be catastrophic going across multiple lanes of highway (from my home street), and entering and exiting my street via the 4 lane highway "suicide lane". I am very worried about this in the coming winter season with snow and ice. The current “oil upgrade” remedy does not resolve the underlying manufacturing defect in the connecting rod and/or crankshaft. Even after the recall service, my vehicle remains unsafe to operate, and the dealer’s own warning confirms this. I request that NHTSA review GM’s recall remedy to ensure that it adequately addresses the safety defect. A true remedy should involve replacement of the defective engine components, not just an oil change, or an immediate buy back of my automobile by the company so I can purchase another safer vehicle. My family and I do not feel safe driving this vehicle, and the manufacturer’s current approach does not eliminate the risk of catastrophic engine failure.

UNKNOWN OR OTHER
The factory exterior paint is failing. Most notable on the hood, roof and back passenger side lower quarter panel area. I just got an estimate to just repaint the hood through the dealership and it was over $3,000.00 (estimate attached) and ballpark estimate to repaint the entire car was around $10,000.000. They indicated that they were not aware of any factory recalls for the failing paint. I've heard that other car owners have experienced the same issue.

EXTERIOR LIGHTING
The headlight adjustment screw is broken. Was never used or adjusted and now the headlights point to the ground. GM does not offer a replacement part for the adjustment screw, the only fix is to purchase a whole new headlight assembly which is roughly $1,000 before installation costs. This causes a dangerous situation since the drivers side headlight points to the ground and it is hard to see in front of you at night.

STRUCTURE
The contact owns 2015 Chevrolet Suburban. The contact stated that while inspecting the vehicle, the contact saw rust on the frame and saw horizontal lines that became progressively worse over time. A dealer was contacted. The vehicle was taken to the dealer, and the contact was informed that wax could be added to the rust spot and that the repair would be out-of-pocket because the failure was not under warranty. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 19-NA-255 (Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 114,481.

ENGINE
Major engine failure in my 2019 Chevrolet Suburban Premier equipped with the 6.2L V8 engine (L87). Despite routine maintenance and responsible operation, the engine recently suffered a serious failure that has rendered the vehicle inoperable. After researching the issue and speaking with several service professionals, it appears this type of engine failure may not be isolated, but part of a broader pattern affecting similar models. Given the vehicle's relatively low age and the severity of the problem, I believe this may be indicative of a manufacturing defect or premature engine wear that should not occur under normal operating conditions.

SERVICE BRAKES, ENGINE, UNKNOWN OR OTHER
No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

ENGINE
While driving along on a city street, the check engine light came on. Once I turned onto the highway, there was a pop from the engine, and the vehicle started missing and vibrating. I turned around and drove the vehicle back home. A mechanic looked at it and said there were a lot of problems and recalls on these vehicles for misfiring. He said the problem is the lifters and they need to be replaced as soon as possible. He encouraged me not to drive it due to it may cause more damage.
