I bought this vehicle brand new off the lot in 2021. Truck hasn-??t had any problems until this year. Every few weeks it will randomly just not want to start, I-??ll usually check the battery and the battery will be completely drained. I can-??t figure out what is causing the battery to drain like this, but something needs to be done as I have literally been stranded places due to my truck just deciding not to start randomly. Today i-??m having this exact problem, my trucked was parked overnight in my garage and I went to go to work this morning and once again the truck won-??t start and battery is drained. All my doors are shut and no interior lights are left on.

The monitor has disconnected many phone calls and rejected software updates. The monitor has been reported to the dealership and has been in many times for harness replacements, harness for the door locks and the timeframe for the repairs was a couple of weeks. The monitor still disconnects calls and I must pull the car over and restart the truck the monitor stays off sometimes until the monitor wants to engage. The history of the truck with this issue has been documented with the dealership

The ESC, parking light, traction control, and engine light came on while driving home. The engine started to shake. There was an issue with braking and steering the vehicle that made it difficult to control. A message on the dash said Service ESC. A report was sent via OnStar Notifications that said An issue with the emissions system is detected. After trying to restart the vehicle a few times, the lights will not go away. The truck is driving rough.

Drove to dealer lifter failure was what was diagnosed. 10000 miles on the truck driven easy, no towing or anything. Dealer also informed me 3 other silverados were there for the same problem! Ridiculous!!

On July 27, I encountered a failure of the rear vision display system on a 2021 Chevrolet Silverado. In short, the system used to display the rearview image went blank, and remained blank, the moment I first shifted the vehicle into reverse. Hence, no rearview image was visible while I was in the process of backing up the vehicle. I believe this may be a noncompliance with FMVSS 111 or a closely related safety defect (I worked in Safety Engineering at General Motors and Ford for a combined total of more than 30 years). I made a video to document this failure, and I uploaded it to YouTube. It is available at the following URL: https://youtu.be/zhBZwteAcBg This vehicle was provided to me as a loaner vehicle while my personal vehicle was being repaired by Quality Chevrolet in Escondido, California. Shortly after leaving the dealership, I pulled over to the side of the road and paired my cell phone with the vehicle. It took several attempts to successfully accomplish this. I then made a hands-free call and then proceeded to drive home. Within a couple miles, I decided to make a U-turn. Given the size of this vehicle, completing this U-turn required backing up. The moment I placed the transmission in reverse, the center display went blank and consequently no rearview image was displayed. Even after I shifted the transmission back to Drive, the center screen (which is also used to display other things like the radio station, time, temperature, etc.) continued to remain blank. However, the audio continued to function (noted at 1 minute and 15 seconds into the video). I decided to make a video to document the condition prior to turning off the ignition as my experience has been that such malfunctions are likely associated with software errors that can be difficult to track down and replicate. I drove this loaner vehicle several other times before returning it to the dealer. On each occasion, the rearview image displayed when the vehicle was put in Reverse.

The lifters in the truck are failing, a brand new truck 12,000 miles on it and the lifters have failed. Which is also leading to an oil problem. They are trying to only fox one bank of lifters instead of replacing both. Due to them wanting to wait until the fail. They have known about the problem and i bought the truck from them not knowing that the engine was a faulty engine. When you pay 70,000k for a truck you are expecting it to last a lot more than 6 months. Which is also causing the bent pushrods on the truck. I bought the truck brand new at the end of January, for the lifters to fail, valve springs, and for bent pushrods, I-??m estimated to be out of my truck for the next 3/4 weeks which would bring it close to lemon law

Car Fire - Started at the rear of the cabin between the cabin rear window and the truck bed The fire engulfed directly around and inside the fuel tank. The car is available for inspection as far as im aware at the tow / salvage yard The safety of myself and any passengers were greatly put at risk. The fire engulfed the inside cabin within seconds, and caused a total loss on the car. The problem has not been identified elsewhere. However the almost exact scenario has occurred in the manufacturers other 2021 model vehicles on the Tahoe and Yukon, with recalls on file for both for incorrect seal around the fuel tank, causing fuel tank fires. The car manufacturer does not want to help at all, they are willing to deal with insurance company and that is it, who will just pay out the value of the car. The police and fire crew local to the incident have ran reports on the fire. No warning lamps occurred before or during the fire. The car was operating as normal until the large explosion. There was no accident, nothing was hit, witnesses described small embers / flames flying up from the truck bed right before the big explosion, indicating there was fuel spitting out and catching on fire.

I lost control of the vehicle when the road became bumpy. The vehicle was bouncing up and down pitching from side to side. I was driving the posted speed limit. This happened on the day I bought the vehicle and I was on my way home from the dealership. At first I thought the vehicle was acting like that because it was new. Nope. It's real. The truck bounces and pitches hard every time I hit a bump in the road. I even drove back to the location where it happened on the first day that I bought it and sure enough the vehicle acted the same way. The entire truck shakes and bounces violantly when I go over bumps. I'm talking about every thing. The second thing is that when the vehicle warms up it starts humming like an electrical type of hum or noise. The humming is coming from the passenger side of the vehicle and I can hear even when I'm standing outside of the vehicle on the passenger side. The transmission slips when I slow down and speed up again. The vehicle that I am driving is dangerious and shouldn't be on the road. City street or highway doesn't matter in my case. The truck will violently shake at the posted speed limit.

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.

The antilock brake system (ABS), brakes, and electronic stability control system (ESC) might not illuminate. This could cause the driver to not know if any of these systems are inoperable.

Infotainment system does not work all the time. Xm radio has no sound at all, or as I am driving down the road the xm radio vulume on its own goes so low you can not hear it and then you can not turn it up or down with the volume control on the dash or the one on the steering wheel. To correct this issue one has to take thier eyes off the road and use thier phone if it is paired with the system or turn the radio to fm or am. After doing this the volume control works on xm. This has happened since I got this vehilce Nov 30,2020 until now on and off.

This truck has less than 500 miles on it and has already had the full engine replaced, problems with the infotanment system and now a complete electrical shutdown. We were unable to get the vehicle to do anything and waited for two hours in the road for a wreaker to arrive.
