I purchased this truck new and it's now been back 8 times for a engine hesitation, misfire, and check-engine light. On this 8th visit, they replaced the "right bank" of lifters on this 5.3L V8. Previous visits have replaced fuel injectors, spark plugs, spark plug wires, and flashed the ECM. I'm not sure why GM didn't replace the left bank of lifters if it's a known bad part (or replaced the engine entirely). Now I'm just waiting for the problem to come back for a 9th time for yet another part to replaced on an obviously poor engine design.
On a 3 year old vehicle, I had a dash full of warning lights come on along with the engine light. Upon checking the code for the engine, it shows a misfire on cylinder 5. Looking online, chevy has a tsb # pip5776c regarding lifter failure. It appears this is an ongoing issue with many of the vehicles as verified by an engine repair shop. They stated then engine may need replacement as they have found in the past. For a 3 year old vehicle with more year of payments this is not right. They know of an issue and after speaking with a dealer, they said its on me because I am over the mileage warranty. I do not have the repair done yet--it is not cheap
Component? Multiple: lifters from bank 2 which caused multiple other components to be replaced consistent with GM protocols such as bent rods. Safety: The vehicle jerked causing it difficulty to safely operate the vehicle which ultimately left stranded. This was also unsafe for other motorist as it was difficult to operate while trying to safely get to the side of the road. The dealer repaired the vehicle after confirming failures. No one other than the dealer inspected the vehicle to date. Warning lamps only appeared after vehicle violently shook.
I have 75,000 miles on my vehicle and in the last 15,000 miles my check engine oil keeps going off. I change my oil every 5000 miles, I am having to add 1 quart of oil about every 1000 miles. I do not see any leaks or old oil on or around engine.
Lifter failure caused several different warning lights and misfiring and chugging. Vehicle never died, but might have if it had continued to be driven.
Vehicle exhibited sudden loss of power at highway speed while in West Texas. Without warning, the vehicle displayed an "engine power reduced" message and the vehicle immediately slowed from highway speed to a maximum speed of 25mph. This sudden reduction in power required the drive to take emergency action to leave lanes of travel for the shoulder. On a road with insufficient shoulder-area, this could have resulted in a collision. Prior to the loss of power, a check engine light illuminated followed by a "Service Emissions System Soon" warning on the driver information display. The elapsed time between the messages and the loss of power was less than 5 minutes. The vehicle did not exhibit any erratic behavior at the time of the warning lights or prior to the loss of power. The vehicle is currently at Bill Estes Ford in Indianapolis, IN. Diagnosis is underway. Indications are that this is related to issues with the emissions control system. The vehicle was up to date on all service at the time of the incident.

I am a volunteer firefighter. On Friday, June 24th 2022, I was responding to an emergency call around 1am. There was an active rainstorm and standing water on parts of the street. While driving through roughly 5-6" of water on the way to the fire station, my truck's engine suddenly shut off and I came to a stop. While stalled, I watched multiple cars travel through the same intersection with no issues. My fellow firefighters helped me get my truck to a nearby parking lot to sit and dry out. The following day my truck still would not start so I had it towed to the dealership where I leased the truck which was still under a full bumper-to-bumper warranty. After initial diagnostics, I was told there was water in my intake and I had to get my insurance company involved for the dealership to continue with the repairs. With no other choice, I opened up a claim and was given an estimate of over $9,500 for the repairs due to the engine being "Hydro-locked". I called GM and filed a complaint. They called the dealership and called me back stating the dealership told them I drove through a flooded road and damaged my engine. I did some brief research online and found several examples from multiple sources with the exact same issue. I feel that this is a design flaw and that this needs to be investigated further as I was stranded by myself, in a heavy rainstorm, in the middle of a roadway at 1am. There is no reason that a 2020 Chevy Trail Boss should not be able to travel through the amount of water that stalled my engine. There was nothing negligent about my actions and at no point was I worried about traveling through the water that I drove through. I feel like I am being treated unfairly in this situation and I would like someone to look through the databases to see how many similar consumer reports there have been regarding this design flaw. This is a major safety issue!

I was driving down I27 10 miles south of Lubbock when my 2020 Silverado 1500 3.0 Diesel engine stopped accelerating. I was going 75 miles per hour and the truck just stopped causing trauma for me and my family we were lucky enough to get to the side of the road. I ended up calling gm roadside assistance and they sent a tow truck to pick us and the truck up. The truck wouldn't engage into drive nor reverse. Once towed to the dealership, Gene Messer Chevrolet, in Lubbock, Texas, a service tech mentioned that a ton of the lifters bending push rods are going out on the late 2019, 2020 model silverado due to cheaper lifters added to the vehicles due to Covid shortage supplies. In essence, they wanted to get these models out with no regard to safety of the consumer. I'm not pleased with the craftsmanship GM has lined out on these trucks, this could've ended way worst. They jeopardized my families safety for profits. Right now the truck is still awaiting diagnostics still won't drive nor reverse per dealer service tech. It's just a terrible situation, the truck is new only has 25,500 miles on it, this needs to be recalled.
Upon starting the vehicle for the second time one day, when placing the automatic transmission into 'D' - Drive, it began to roll backwards as if it was in Neutral on a slight decline and the brakes had to be applied to avoid rolling downhill backwards. After attempting to place it back into 'P' - Park and back into 'D' - Drive and attempting to try 'R' Reverse to try to get it to move forward properly, it would not go forward. After several tries and restarting the vehicle completely, it finally attempted to move forward but would only do so at a reduced speed and would not respond to the accelerator pedal beyond a certain amount. After trying again, it appeared to move forward a bit better, but then upon stopping at a stoplight and attempting to pull out for a left turn onto the road, the speed again was reduced and I had to immediately place it into 'R' - Reverse to avoid an accident due to oncoming traffic. Finally I was able to get it to move forward a bit better and was heading directly for the dealership but since the power just was not getting to the wheels (transmission?) I pulled over and shut off the truck for a few minutes. Upon starting the truck again, it seemed to move forward better after that but had the 'check engine light' illuminated. The truck is at the dealership now, they have had it nearly a week and said they will not begin to look at it for another week at least since they only have 2 technicians who can look at it.
Vehicle has approximately 15789 miles. Loud taking sound coming from engine began November 2, 2021 as I was on Highway. Dealer advises all 8 lifters and cam need replacement. My investigation reveals that this is a persistent problem with this type of vehicle and many reports have been made about this same issue throughout the USA. My service advisor advised me that they have already repaired several of the same vehicles for the same problem. Engine is defective and requesting a recall to release entire engine now that this engine will need major overhaul.
Service ESC and Parking Brake error. Drove to work with no issues. Started up to drive home and I kept hearing a "Ping" noise like hail hitting my roof. Then I thought my transmission was going out while driving. It is almost like it is firing out of order. Dealership ordered multiple parts: Misfire in cylinder 4 plus issue with the heads and push rod. GM decided that the issue it to be repaired rather than a new engine be put in.
