Bought the 21' silverado about 18 months ago, recently the truck began to sound and drive terrible, it was found to be a bad high pressure fuel pump, bad lifter, and damaged camshaft. Dealership acknowledged that these are common issues w/ this model & year of vehicle and the parts are defective parts that they use in the manufacturing process of this model. They deemed it was out of warranty range as it's still under year 5 however I exceeded the powertrain warranty by 10,000 miles so they will not cover the issues and damage.

At 62000 miles, I was having a transmission problem but had no check engine lights associated with the issue. The day I took it to the dealership for the transmission, the check engine light came on for the first time ever when I started the vehicle. The dealership first said it was a faulty solenoid on the purge valve, replaced that part, but it didn’t fix the problem. The dealership then said it needed a new fuel pump control module, which was heavily back ordered due to demand. I needed the vehicle because it had already been at the dealership for a transmission replacement for many weeks and is my only transportation. The dealership told me other vehicles were there for the same problem, parts were on a national back order and being rationed to dealerships around the country. They could not provide an estimate for when my vehicle would be ready and pushed me to trade in my vehicle as a solution. The sales manager offered a very low trade in value, told me I couldn’t get the part faster by purchasing it myself, and was very pushy. She said my vehicle was devalued because it didn’t have the fuel pump control module needed for the check engine light to turn off, and had a history of transmission problems (even though it just got a new transmission). I got frustrated and ordered the new GM part from summit racing and had it on my doorstep in two days. I took it to the dealership and all of a sudden they had received a shipment of this part, and replaced the faulty one in my vehicle. Their repair resolved the problem, but I still had reliability concerns. Despite all repairs being completed, the sales manager said the vehicle trade in value remained unchanged. It was a complete nightmare and I felt my vehicle was being held back from repair resolution to convince me to trade it in for a new truck. I kept my vehicle and extra part I ordered in case this happens again.

July, 10 2025 My 2021 chevy Silverado has stalled today in the middle of the road. When trying to start, it sounds like if it wants to turn over but it won’t. I bought a brand new battery and problem is not resolved. I did some digging and sounds like fuel pump will not come on. This truck is only 4 years old and I should be having these issues. Please help thanks

On thursday feb 18th is was snowing when I left work, drove around the beltway approximately 30 miles going on average 30-40 MPH.no issues just bad roads. Right after I left the highway and turned on to a main road, I was approximately 1 mile on that road in the middle lane driving straight at about 25-30 MPH when my new 2021 silverado (5000 miles) loss power. The battery and check engine light came on with no engine power. As the vehicle was coasting attempted to get off the main road, but didn't make it due to the snow covered roads and slush. Ended up in a merge lane still in traffic and was almost hit numerous times. Tried to restart and get to a safe location, but when pushing the start button the silverado would crank extremely long period of time and then final cutout. Was on the phone with on star where they put me in contact with the local police department who never showed and then left me a message they were coming out due to the inclement weather. Thanks. After talking with police dispatch on star setup a tow truck, but gave them the wrong address which was more than an hour away from my location. Once back on the phone on star stated they had to call the same tow truck driver/company which of course he was over an hour away. Once the tow truck driver arrived 3 hours after my truck broke down he said he was originally only 10 minutes from my location prior to on star sending him to the wrong location. What a mess. Have a loaner car because I have been told a fuel pump is on national backorder. Also that they will be replacing the valve springs which is another issue I think? Hoping to know more this week.
