While driving the active fuel management changed my truck from 4 cylinders to 8 cylinders. This is when I heard a loud bang and a bunch of lights came on the dash and my truck started shaking and shuttering. I was able to regain control of it, but I came close to crashing. I now require a whole new engine at 100000 miles. After talking to multiple shops this KS a known issue. While they dont always catastrophic fail, mine did and almost cost me to crash.

We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

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.

I have a 2019 Chevrolet Silverado 1500 lt and I am having issues with the transmission bucking, hesitating, slipping. I am also having issues with the variable timing system. The variable timing system started acting up last year and when I took it to the dealer they replaced it and I was charged over $400 for it to be repaired. It happened again the beginning of this year and I took it back to the dealer. They told me the oil was dirty and suggested an oil change to fix the issue. I had the oil change done and now I am having the same problem again and have already had the oil changed. I need help since I am paying for a vehicle that is sitting in my driveway not being able to be used. There are 6 codes that have popped up including the variable timing system, cylinder 4 misfire, brake system, and I'm not exactly sure what the other ones are.

I purchased my truck in December 2018 which is a 2018 Chevrolet Silverado 1500 4x4 crew cab automatic from servco Chevrolet dealership in waipahu, hawaii and making monthly payments for my truck February of 2019 truck runs good and purchased the warranty also had my oil and service changed when time is due which I always kept up. [xxx] and mileage was 40k while leaving work to go home at a stop light was red once turned green I pushed pedal to go and truck just changed noise tone started to run like rough idle, loud tapping noise coming from the engine, shaking and check engine light came on almost causing me to get into an accident. I pulled on the side and checked what was going on and heard the tapping noise from the motor. So I made an appointment with service department with servco Chevrolet dealership where I bought my truck from and spoke with the service tech for my truck to go in for repairs due to issue. It took 2 to 3 weeks for repairs to be complete and service tech informed me that I'm not the only person to have that issue which had to do with the lifters and camshaft with these motors but gm never came out with any recalls due to how much people has the same motors with the same issue. So luckily it was still covered under warranty but said the problem might come back and would just replace the faulty lifters and camshaft. So in August of 2023 my truck has the same issue but wasn't covered under warranty anymore and mileage is 61k and missed the warranty repairs that was for the lifters which I got it scanned cause check engine light and same issue and code was p0016. So I called servco Chevrolet dealership in waipahu again and spoke with the service technician which he told me I just missed the coverage of the warranty repair and only way to get it fixed I would have to bring it back for them to scan and roughly would range from 4k to 8k to get it fixed. So my truck is parked in my garage and hasn't been moved but paying for truck. Information redacted pursuant to the freedom of information act.
