POWER TRAIN
The sudden rear wheel lock up recall that GM has released for the 2020+ Silverado's with the 10-speed transmission does not go far enough. The recall simply reprograms the PCM to alert the driver 10,000 miles prior to the valve in the valve body failing, puts the vehicle into limp mode, and extended the warranty on the valve body to 15 years or 150,000 miles. GM states there is no fix available and this is not correct. NextGen Drivetrain has developed a fix for this per their website [XXX] ). On their site they also provide videos of trucks experiencing the lock up where it seems that the vehicle downshifts to 2-nd gear at high speeds and creates a violent jolt. This is extremely troubling to me as these vehicles are meant to tow, and I am very fearful that this issue will happen while towing a long trailer while my family and I are traveling and putting them in danger of an accident. It is very concerning to me that NHTSA would allow for this type of a "FIX". I am not sure if you have seen the videos of this issue happening, or know that a fix does seem to have been developed. I ask that you please reopen this investigation and revisit the way GM is handling this recall, and look into the fix that NextGen drivetrain has developed.

ELECTRICAL SYSTEM, POWER TRAIN
When I would put the truck in park and proceed to turn it off, the computer would tell me the truck was not in park. I was told at the dealership that the transmission was in park, though the computer wasn't communicating correctly. Not only does it pose a risk of draining the battery, it is a safety issue. If I were to park on a hill, the only confirmation that my truck is in park is what's said on my dash.

SUSPENSION
When the truck was less than 2years and less than 20,000 miles old it developed a clunking noise in the rear suspension. Sounds like 2 heavy pieces of metal softly being knocked together. The dealership inspected it and replaced both rear shocks. The noise was still there. The dealership replaced the left leaf spring assembly. This temporarily eliminated the noise. The noise came back at just under 3 years and 30,000 miles. The dealership inspected, but couldn't find the source of the problem. The noise has only worsened since then, and at a recent visit to the dealership, they could clearly hear the problem. I was told that it is the result of worn cushions between the leaf springs. I'm concerned that the truck may be unsafe. I've been contacted by GM, and at this time they are looking into how to fix it, and who should be responsible for the repair. I can't imagine that mine is the only 2020 Silverado with this problem, and think there must be other reports of a similar nature.

POWER TRAIN, ENGINE
I purchased a 2020 Chevy Silverado 2.7 turbo RST from Greg young Chevy in Omaha Nebraska. Upon purchasing this vehicle within 20 days of ownership I got a check engine light indicating code P2090 for exhaust camshaft position sensor. The truck was taken back to the dealership and they at first tried to just clear the code and give the truck back however I put my foot down and requested them to look further into it. After weeks of them having the vehicle they determined there was an issue with the pcv oil separator and they replaced the part allegedly. After reviving the car back they strongly suggested I purchase an extended warranty telling me “you’re going to need it” we purchased the warranty only to discover the code reappearing less than 2,000 miles later and a tic sound in the engine. My independent research has concluded it’s a lifter failure and those lifters are now slamming into my camshaft causing excessive damage. After getting the code read more in depth I can confirm they again just cleared the code and an oil leak is still existent in the engine. This causes the auto stop to disengage which makes the vehicle leech forward when at rest while my foot is still present on the brake as the camshaft does a full rotation to adjust and correct itself to the sensors suggested position. On average this moves the vehicle approximately 1 foot forward and could lead to me damaging my vehicle or causing harm to people in crosswalks.

POWER TRAIN
While driving the truck it will have a hash upshift which has happened on five different occasions plus on two other occasions after first startup and drive the transmission will not shift out of third gear it will just wind up the RPM's as if transmission is stuck in third gear. I have to let off throttle then accelerate and back-off a couple of times to get transmission to shift out of third gear. The software upgrade is not a fix for this recall as it does not address the problem. The valve body installed in these ten speed transmission is a manufactures design flaw along with using inferior parts required for the safe operation of this vehicle. There are documented claims of the valve body failing causing catastrophic failure of the entire transmission and GM Corporation will only cover the valve body. GM has told it's customers that they will warranty the VB only that the other damages are not covered. The recall letter I receiver indicates that only the VB is covered. This is unacceptable. It is because of the VB failure that the transmission will suffered catastrophic failure, Without a properly functioning VB the transmission cannot receive the lubrication it needs to function properly. I have not had the software update as their are reports of customers trucks going into limp mode shortly afterwards. Their trucks are then parked on dealer lots as parts are currently unavailable for weeks at a time in some cases months. These customers use these truck for their livelihood and they invested a large amount of money purchasing these trucks only to be told So sorry GM will not cover your claim even through it was our defective VB that destroyed your transmission. These trucks are not cheap to purchase nor to properly maintain.

ELECTRICAL SYSTEM, SERVICE BRAKES
My break system failed twice in 2 weeks. On Feb 01, 2025 around 5:35 pm, I almost ran over a dog the first time because I lost access to breaks and emergency breaks and could not stop going through my neighborhood. Today on Feb 13, 2025, I had picked my son up from school, and the breaks went out after we left the school. This time I almost ran into a car but had to turn off to the right to avoid hitting it. My son and I could have injured the person driving in front of us and ourselves. I looked up the problem, and it seems that many others have faced the same problem. When I turned off the truck for 10 minutes, the system would reset itself and start working normally again. I took the truck to the shop, and it is currently there so they can run tests on it. I recorded what it looks like on the dash when I lose all braking.

ENGINE
The engine is blown. Our GM Dealership where we purchased it, inspected it and says the engine cannot be repaired and must be replaced. And independent garage gave the same diagnosis. Went from running fine one day , to bucking and stalling in traffic causing a hazard to everyone on the road. Check engine light, check brakes, stabilitrak, ALL the lights on the dash were on like a Christmas tree. It doesn't run now. Currently sitting in our driveway now unable to be driven for three months as we don't have $10,000.00 for a new engine, and the extended warranty we purchased through the dealership expired 4 months before it blew up. We are now making loan payments on a GM vehicle that did not even last the length of the loan. Seeing a report on this exact issue, we did not even know until today that there was a place we could send in a complaint to. You are welcome to inspect the truck, but you would need to come to us, as it cannot be driven. Where can we get any help with this? Please help.

SERVICE BRAKES
After driving and doing errands I tried to pull truck into garage and noticed it was hard to move. It seemed like brakes were stuck on despite not applying brakes. I pulled out of driveway to drive around block. Lost all brakes while driving down county road at 50 mph. Check engine light on, brake failure warning on, warning light that speed limited to 43 mph, ABS light on. Eventually able to stop. Turned off engine for a few minutes. Restarted and brakes all worked again although check engine light still on. This could have been deadly on a steep road or on ice or in traffic. I see online that this is a common problem with Chevy trucks although no recall has been issued for this one. I am very concerned that this truck is not safe - for me or anyone else on the road with me. I have not taken it in. I live in the country, some distance from a dealership so nothing has been confirmed. Nothing like this has happened to this truck before and there was no other warning. It is available for inspection but is my only transportation.

Vehicle started miss firing along the highway without any previous signs of problems. The vehicle was driven straight to our home and then to the dealership a few days later. We were told there, the lifters have failed. Once they started the repairs we were also adviced the cam have suffered significant damaged and needed replacement as well. The vehicle was only inspected at the dealership once it was dropped off. The first and only sympton of the insurance was the day it failed.
