ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
The engine light is blinking while driving on the highway, it comes and goes, I have a video for that. Also it has a ticking noise and I’ve had the noise since I bought the truck and took it multiple times to the dealership, first it was the pump they replaced for free but the ticking never went away, I took it back and they said that all the trucks tick like that, and all that should be documented. Also while sitting still it sounds like the truck is shacking just a little. I have an appointment to which I have to pay $250 for them just to look at it. I think that my truck should be up under the new recall for the 2021 Chevy Silverado because my truck is knocking and also throwing off a blinking engine light.

ENGINE
While driving at 35 mph my check engine light, Service Parking Break light, ABS Maintenance light all came on and my truck lost power to a point I could not go over 10 MPH. It started chugging and running very rough. Fortunately I was close to home and got it in the driveway. I called the dealership to set and appointment, tried to drive it down my driveway and couldnt get it over 10 MPH. I called a tow company to take it to the local dealer I purchased from. After a couple days the dealership called and said there is a lifter problem but wasnt fully into the engine to see if there was more damage and would call me once more testing had been done. I have photos of the tow company tow bill ($169) and a photo of them lowering the bed to put the truck on it to haul to dealer if needed.

CEL with code P1098 - which is a coolant control valve issue. Engine is not properly distributing coolant potentially causing an overheating condition. Dealer informed me that it is dangerous to drive and it is recommended that it is left at the dealer until it is repaired. If driven and other issues occur do to this failure the warranty will not cover damages. The failed part - coolant control valve is on national backorder and there is no eta on when the part will be available, no vehicle has been provided and the replacement part appears to be no different than the original except for a different model number.

While driving on the highway the engine shimmered and shut down. I lost all steering and braking power. After 20 minutes I was able to restart and drive off the highway at a reduced speed. upon exiting the engine died again. The following day I took it to sunrise Chevy in Glendale Hights IL as this was just down the road from where it sat all night. Service rep called and said I need a new engine with only 81000 miles. It was major lifter failure he said. Job was done at a cost of 9417.89. With less than 1000 miles on the new GM engine I was coming home on [XXX] at night when I lost all power to steering and brakes, dashboard lit up. Made it to the shoulder and towed back to the dealer. Once again major engine failure. At least this one was under warranty. but still very dangerous on the highway. Needs to be a recall please.

POWER TRAIN
Transmission jerking violently while driving at low RPM 1000-1500 RPM. Occurs daily. Shudder and vibration as vehicle is slowed approaching stops. Effect and feeling is unsettling to driver and passengers. Can be recreated but is also intermittent at times. Dealer has avoided fixing as it is not 100% consistent. Asking me to drive until failure which is unsafe and could lead to accident or stranding.

Tailgate opens by itself. This happened 3 times in 2 hours while the vehicle was parked. I tow a 5th-wheel trailer. If this happens when towing it can cause a catastrophe.
