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.

Driver side front marker light bulb not working after 700mi. Not a big problem but annoying enough for a 2 week old, $49,000 truck.

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.
