Too whom it May concern Our 2021 Chevrolet Silverado 1500 had check engine light come on 7/5/21 called Chevy Service department was told Bring vehicle in if Light flashes, Light went off Service department said if it happens again to bring it in. It happened again 10/12/21 took vehicle in to service was told it was something too do with lift & Technician reset something & Did our first Oil change as this was a New Truck bought in 01/13/21 from them. Well 10/25/21 My Wife & I were Driving when we heard a loud banging noise coming from Truck we Also lost Power & Truck was shaking Bad. Called Dealership asap was told bring in Now. Service department said Engine was basically shot that engine lifters went bad & Probably had a bent pushrod. So Basically a catastrophically engine failure on a Brand New 2021 Chevrolet Truck with 7000 miles. Had this Happened on the highway @ highway speeds with sudden lost of Power This could lead too an accident & possibly a loss of Life. The Sad part is this has been a ongoing issue with the 5.3 & 6.2 engines since 2018 & Chevrolet is aware of it. They have No Fix and are installing the same defective Parts back only too have same issues again & again. Spoke with Corprate & They have No answers or cares my Wife said she would never drive Truck again especially since admission from a Chevrolet service Tech said it will happen again. This has been Long enough Chevrolet must recall these Vehicles & Apparently its All GM engines 5.3 & 6.2 whats it gonna take someone being Seriously hurt or Killed!!!!
Turned on my 2021 Chevy Silverado in my driveway and esc service notification popped up and check engine light popped up as well and then a loud clicking sound came from under the hood which turns out to be a bad lifter.
Engine began to shudder, vibrate and lose power on the highway. Multiple codes were eliminated - check engine, service park brake, service ESC, service emissions system. Loss of motive power is a safety issue. Vehicle currently at the dealer for service. I have been notified it is a lifter issue and major engine repair required. GM Authority and other online forums identify this as a known major field issue and continuing to grow.
while stopped, engine running, in gear, foot on brake the truck lurched forward approx 2-3 feet. when i tried to pull forward the engine was revving a much higher rpm's. moved down road approx. 1-2 miles, tried to turn around to return to a dealer near by and truck would not go into reverse...on-star reported to get engine/transmission service soon. reported to dealer, they checked the (code)? truck continued to run well....till it happened again....now it has happened a third time dealer has ordered parts to try to correct. dealer is trying, but no one seems to know what to do...
Driving along a highway at 65mph and a lifter dropped or rocker arm failed catastrophically. Loud audible pops and bangs without warning no "warning lamps" lights or notifications at all. Towed it to dealership under their recommendation as opposed to driving it there. Also there's a clicking metallic jingle jangle in the driver side from unless 4wheel auto is engaged.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the vehicle inadvertently stalled. Several unknown warning lights including the check engine warning light and the transmission warning light were illuminated. The contact stated that he was able to veer to the side of the road and turn off the vehicle. The contact stated that he restarted the vehicle, but the vehicle was shuddering and making abnormal sounds while driving. The vehicle was taken to the nearby dealer who diagnosed that it was a manufacturer-€™s error and that the engine and the gasket needed to be rebuilt. The manufacturer was notified of the failure and advised the contact that they would replace the engine instead of buying back the vehicle. A case was opened. The vehicle was not repaired. The approximate failure mileage was 15,000.
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
Faulty lifters causing the truck to throw piston rods. This causes malfunction of the traction control, parking brake, transmission, auto locking rear differential. I have had my truck in the shop 3 times for the same issue all within the 1st 10,000 miles. This particular motor has been taken out of production. Upon speaking to mechanic managers at multiple GM dealerships they were not surprised and personally gave me advice on the lemon law. My truck, which is my 1st brand new vehicle, has been out of service now for a total of 45days. I have still made payments up to date. The dealership offers a car or small suv while repairs are being completed, not a truck! Beware of the 5.3litre ecotec3 v8 motor.

Engine started to backfire/pop through the intake while driving. I had it towed to the dealership as it wasn't drive-able. They told me it was major engine failure, broken valve spring or bad lifter but won't be sure until the engine is torn down. I was driving on the interstate and the engine immediately started popping which slowed me down drastically. This was on an interstate road where there is a lot of traffic and it is higher speeds than regular roads. I was afraid of being hit from behind before I could pull of the road. The dealership confirmed it has major failure but have not inspected it yet. There was no symptoms/warnings or warning lights.
While driving down the interstate about 450 miles into my trip, my engine started missing and knocking. I pulled off on the next exit, about 2 miles, to call for a tow. The repair from the dealership states: "CS: CUSTOMER STATES STARTED KNOCKING AND WOULD NOT ACCELERATE. Caused by verified customer complaint- heard loud ticking/knocking noise coming from the left bank- removed [left bank] valve cover and cranked engine and found the cylinder #3 intake rocker arm wasn't moving. Upon disassembly found the #3 exhaust push rod bend."

I drove my truck to see how it felt. I immediately smelled antifreeze, but the temperature gauge read 210 which is normal. Upon accelerating up hill, I thought I felt a miss in the engine. When I arrived at the Clinton, TN dealership, the technician plugged in the code reader and it showed a misfire in the engine. I left the truck with them and they gave me a loaner.

----warning light flashing at 103 miles on vehicle, , dealer reset ----450 miles on vehicle stalling, ,warning lights ECM - engine systemp2635 the engine and transmission system is not performing as expected. An issue has been detected in the fuel management system used to maintain, control and monitor fuel consumption. If the check engine light is flashing, a misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Please reduce vehicle speed, avoid hard accelerations, avoid steep uphill grades, and reduce any cargo loads such as a trailer. If the vehicle is continually driven with the check engine light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to future repairs. Vehicle was towed to maltbie Chevy and has been there since Feb 24th
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.
