WHEELS, UNKNOWN OR OTHER
On August 17,2025 I was driving on the freeway when I heard a loud bang and I thought my tire blew but it also felt like I hit something, however I pulled over and tires were ok. I proceeded to go again and this time if can feel my rear tire lock up and then let go. I pulled into a parking lot and my tires had some strips on them as if they where dragged.

POWER TRAIN
Rear wheels of vehicle locked up momentarily mutliple times while driving between 45 and 65 miles per hour. Originally happened multiple times while towing a travel trailer but subsequently happened again with no trailer being towed. No warning lights or other sign of a problem leading up to any of the malfunctions. After locking up for approximately a quarter to half a second, the wheels release and the truck drives normally. Sudden wheel lock up could lead to loss of control or cause a vehicle to collide with the back of affected vehicle. Issue was reproduced by dealer service department and they recommended a new transmission valve body. This seems to be related to the recall for the transmissions on the diesel models of this truck but the gas trucks were excluded from that recall.

ENGINE
I was on a trip to Iowa and noticed a loud ticking noise starting in my engine. There was no warning lights on the dash to indicate any problems. I checked the oil and notice it was not registering on the dip stick. I added over a quart of oil and the noise continued. My truck was just at a dealer 2 weeks prior for an oil change and they noted that everything was good and in proper working order. No leaks or no other issues. I set up an appointment at a chevy dealer at the destination which I was traveling to for a check up. About 60 miles from the dealership, my check engine light went on. I immediately stopped and checked all my fluids which were showing normal ranges. I dropped my truck off for inspection and they advised me that my lifters need to be replaced. I authorized the repair and after the new ones where installed, they tested my truck and noticed that there was still a ticking noise coming from the engine and was not holding any oil pressure. They advised me that the motor needed to be replaced at a cost of almost $15,000. I will request all pictures and videos taken by the dealership for further inspection if needed.

While driving in Southern Utah my truck gave me a Service ESC (Electronic Stability Control) Warning, Service Parking Brake Warning, and check engine light that was for code P0303. I had the vehicle towed to the local Chevrolet dealership and it was diagnosed with lifter failure and camshaft damage because of the lifter failure. Safety was compromised because of the failure of the ESC and the loss of power and stability of the engine. I didn't receive warnings prior to the failure. This appears to be a well-known issue with several service bulletins issued for the vehicle.

Had sudden engine failure at 82k and have been told I need a new engine. Can't afford it, GM says there's nothing they can do to help cover the repairs. I have a new engine on backorder, nobody knows when it will be in, they told me they have other customers who have been waiting for new engines for months.

VISIBILITY/WIPER, UNKNOWN OR OTHER
I noticed that the carpet behind the seat was wet and moldy in the truck so I started looking and noticed the rear window was leaking in two areas. This has obviously been going on for a while as it explains why the kids have been complaining about the smell back there. Since Florida is sub-tropical mold and mildew is a problem and a health issue. I investigated and found hundreds of complaints regarding this issue with failed sealant and cracks. I also discovered a service bulletin that describes the issue but GM refuses to fix it since they say it's not a safety or mechanical issue. Well, I happen to disagree with that since the leak causes the window to fog up and an unsafe environment for people to breath in mold spores in a small space. So, my visibility is impaired and I have to suffer with respiratory issues? This seems to be reason enough for them to perform a permanent repair at their expense, not mine and they can take it out of the designers pay, not mine. Can you help with this?

There was a significant oil leak that was diagnosed during a routine oil change in March of 2025. The dealership that identified the leak attempted to pass it off as something that was out of warranty even though the vehicle had an additional six months and 45,000 miles of warranty (3.0 diesel). The leak was significant enough that loss of oil could cause the engine to fail and result in a crash. Subsequently, another dealership identified the leak and repaired the seal around the lower crankcase. It did not repair the oil leak- there are three additional reports/complaints to file.

This is for the second oil leak that occurred in the 2020 Chevrolet Silverado with the 3.0 diesel engine. It was identified as a leak in the oil pan. The previous repair was for the lower crankcase seal. The service advisor at the dealership stated this is another problem area with the Chevrolet 3.0 diesel engine, and a defect from the manufacturer. He also mentioned it is a common repair they complete on these LM2 engine. It is worth noting, the initial repair didn't last 60 days before another oil leak presented itself. This is the second of four repairs that were done on this vehicle. **No loaner vehicle was given during the repair.**

The second oil leak repair and the first repair for the oil pan failed within one week of the previous repair. This is the third oil leak that occurred in the LM2 engine in the 2020 Silverado. It was identified as an additional leak in the oil pan which had already been repaired the week prior. This is a failure within seven days from the previous repair. I lost 1/2 quart of oil during a 650-mile drive back from vacation. I took pictures of the oil level before leaving and driving home. During our drive, we passed through an area called Yermo where it was 107 degrees at 11am. The two closest Chevrolet dealerships are either 45 minutes or 1.5 hours one-way. I was incredibly frustrated since imagine being stranded in 107-degree weather with your family on the side of the road unable to run AC. It is a serious life, health, and safety issue at this point. I called GM and opened a case expecting them to assist me with the issues with the truck. Fast forward to today, I spoke with Jill at GM, they closed the case without even reaching out to me. This was the third of four oil repairs that have been conducted on my vehicle and the LM2 engine. It isn't a safe engine to have. **No loaner vehicle was given during the repair.**

After three oil leak repairs in my LM2 3.0 diesel engine in my 2020 Chevrolet Silverado RST, you would think that would be enough to repair the manufacturer's defects, but it wasn't. I think the saying is fourth time is the charm? The third repair which was a second oil pan lasted a whopping 48 hours before leaking. This time it ended up being the timing chain cover that was leaking. Again, the service advisor mentioned that these are known to leak too due to a defect from the manufacturer. I even got a call from the service manager, and he said that anything area that could and does leak oil on these LM2 engines has been replaced and/or repaired, so I should be good for the future. I called into GM as per their instructions to update them on the fourth oil leak, and where the repairs were taking place. Fast forward to nearly two months later, and no one from GM attempted to contact me, and Jill stated that the case was closed and wouldn't disclose why. The only thing she could do was open another case. I declined since GM couldn't be bothered to address the issues they know they have in the LM2. The dealership the work was done in, the service advisors, the service techs, and the service manager all discussed in great detail the issues Chevrolet is having with the 3.0 diesel engine. GM knows this and refuses to address this. At this point, my vehicle spent 37 days in 2.5 months at the dealership fixing oil leaks that at any time could have caused engine failure and resulted in a crash. This truck is our dedicated family vehicle as my wife and I each daily Subaru WRX's. GM has done nothing and will do nothing. Someone needs to issue recalls to address the oil leak issues with the LM2 before it results in someone's death. I wish I wouldn't have wasted time contacting GM. I should have filed these complaints and got legal representation for the Magnuson-Moss Warranty Act. **NO loaner vehicle was given during the entire 37-day repair duration.**

When it gets hot it'll lose power at the pedal and it will randomly come back causing the drive train to jerk back and forth throwing full related codes that go away once the truck has cooled off. Took it to a shop and they couldn't get it to throw a code. This will be the third time it has happened. This time it doesn't throw a code

Motor suddenly loss power and load knocking noise. After taking it to the dealer they said that number 3 cyl.connecting rod had an issue . This sounds like the same recall for the 2021 to 2024 6.2 engines. They gave me a quote for a new engine ( 20000) that was not available for 4 to 5 weeks if not more. I was on vacation at the time and ended up buying a new truck from them. I was not happy.
