2021 Chevrolet Silverado 1500 complaints

Power hesitation, along with loud knocking sounds coming from the engine. Cause truck to completely shut off while driving 35mph. No warning lights or anything came on until complete failure

Per the repairing dealership, a lifter went bad. GM will not replace all of the lifters, just one side of the engine, due to the vehicle having over 8000 miles. Mine currently has 12,500. I no longer feel safe knowing that GM is replacing only half of the know defect with new parts that have the same issue (Told to me by the repair facility.) The vehicles engine could fail again, resulting in loss of acceleration. No warning was observed during, however after the fact, check engine and other warning lights were illuminated.

Body control modules sas modules no communication service esc light and traction control lights coming on vehicle looses all steers ng when lights come on at any speeds it says service esc power steering loss drive with caution have had it into multiple shops and no diagnostic scanners can get into the 3 systems there 6050 miles on vehicle we haven’t gotten in a wreck yet but that is totally not out of the question it will happen and when it does its going to be devistating

Engine misfire due to faulty valves which caused vehicle to lose power and stall. Check engine light began to flash on dash. Took directly to Chevrolet dealership. Dealership confirmed faulty valves and bent pushrod on left side of engine. Dealership to repair engine under warranty. Dealership stated that right side engine valves had already been replaced in November 2021 at approximately 13,000 miles. This was before I purchased the truck in May 2022 and I was not made aware of this repair. Truck now has 22,900 miles. Dealership stated that this is a known issue with Chevrolet 5.3 liter engine and they preform similar valve replacements on this engine at least once a week.

Truck caught on fire while driving down I75 interstate in Florida. No component or system failure lights where present. Smoke was smelled by the passengers and within seconds the truck was on fire. The safety of the passengers was at FULL risk, and lucky to be alive! The truck was full engaged as soon as the truck pulled over on the side of the interstate. Investigation by GM & Insurance company took place. The truck is available for further investigation. We are unsure how the fire started. It did come up from both sides of the cab, and very quickly. Nothing has been confirmed by any inspections completed by GM & Progressive. GM & the Service Dealer are not engaging as they should be.

2021 Silverado RST, 5.3. Started having strange loud random clicking sounds when first starting. Would loose power, at take off or when trying to accelerate. This was at 9400 miles on the vehicle. Was not showing any check engine light or issues on dash. When examining engine compartment, found loose bolts, that had broken. Took it to local Chevy dealership, acted like there was nothing wrong with it. Instantly trying to get out of performing work. I had a feel it was going to be lifter issues. Found out while there around 4 thousand miles it already had lifters replaced. After debating with them for two days, and trying to convince them there was issues. They finally found multiple problems with lifters, misfiring, rocker arm not moving due to collapsed lifter. They found broken bolts in cylinder heads. Ended up having to replace all left and right side lifters.

Dealer said lifters failed. Was stuck in middle of interstate for 2 hrs

I was not personally at risk during my incident, but I can see how I could have been if my situation was a different. My 2021Chevy truck suddenly lost engine power at a traffic stoplight. It almost stalled coming to a stop. Then when trying to accelerate, it had very low power, and was stumbling. I was only a mile from home, and not busy traffic, so I managed to make it home. Driving very slowly with the engine clearly under very low power. No CEL or warning lights came on. After getting it towed to the dealer the next day, the dealer informed me it was a failed lifter and bent pushrod. After a little google searching, I found it is a common failure in newer GM V8s. I also learned my truck was built in a date window that GM issued a Service bulletin for lifter failures. According to forums and Facebook pages, Many other owners have had the same problem. Even 2-3 time failures with some owners. Even after repairs. Either in the date range of the bulletin or outside of it. My specific situation wasn't dangerous, but I could see how it could be, if I were on a busy highway, or if the truck completely lost power. As far as I see, no Recall has been issued, just many internal service bulletins over several years. And even a class action lawsuit in regards to lifter failure. My truck was fixed with all lifters replaced with an updated part number. 5000 miles since the repair. Gm did a good job with the repair, and after some communication with GM customer service, they replaced all

My truck has had lifter issues twice now. Finally, a new engine had to be installed and I have recently began getting the check engine light along with sputtering sensation while the truck is on idle. Also, I purchased this truck, brand new, and I was without it for close to six months.

Collapsed Lifters an Bent Push Rods

I was on interstate 85 and the whole truck started shaking and check engine light, service ESC light and service parking brake light came on. Thankfully I was near and exit ramp and got off as I had almost no power. I limped my truck back to the dealership where they diagnosed it as lifter failure and replaced both banks of lifters. This is a known problem with General Motors and is simply a matter of time before a terrible accident occurs.

MY PICK UP WAS HIT FROM THE REAR THE DRIVE SHAFT BROKE AT THE WELL AND THE REAR BROKE BOTH SIDE OF THE AXLE TO THE HOUSING OF THE REAR I HAVE PICK OF THE REAR AND THE DRIVE SHAFT.

Lifters blew in my brand new engine with only 18k miles while driving. Engine was shaking & knocking & lost power when trying to accelerate.

I have a 2021 Chevy Silverado. The #3 Cylinder has failed and an all new lifter kit needs to be installed. Truck was knocking violently and died. Dealership stated the parts on back order nationwide and they have no clue when replacement parts will arrive.

At 7,316 miles my 2021 Silverado 5.3 V8 had lifter failure while driving, the truck would not accelerate correctly and I was forced to pull off the road, luckily it was able to turn off at the next road before the vehicles behind me caught up. The check engine light was blinking and was making a lot of popping noises. I was able to take back roads and drop it off at the dealership for repairs.

This 2021Chevrolet Silverado 1500 LT Trail Boss I purchased new April 2021. Since I have owned it the check engine light would flash randomly with or without a load and now just this past weekend (7/17/2021) the check engine light stayed on. Took it to the Chevy dealer for repair and was told it was a lifter problem. I recently just purchased a camper, well under GM allowed towing capacity, and worried that if the engine should fail either up hill or down hill that there could be loss of control of vehicle from other systems shutting down.

Vehicle began having issues at 3 months old... Random service messages, defective headlight, wierd engine noises at startup and stalling upon acceleration/deceleration. I took it to the dealer several times about the issues I were having but they always say they aren't able to replicate any issues. 3 months later I was driving on the highway and the engine started knocking. Had it towed to the dealer and it took them 6 months to replace engine, tcm, starter, and other parts. After finally getting the truck back, it was still stalling and there was a check engine light... Dealer did not reassemble the vehicle properly and several parts and bolts were still missing. It went right back in the shop and catalytic converters were replaced. I also mentioned missing parts and bolts. I get the truck back again and it still seems like it wants to stall. I was turning into a parking lot a few days later and it seemed like it wanted to cut off. While I was distracted trying to see if the truck cut off, I hit a small pole... Truck was damaged way more than it should have been because the dealer did not reassemble it properly. Body shop said my bumper was only held on by 2 bolts and several other bolts and pieces were missing. They said if my bumper was attached properly the damage would not have been as bad. The vehicle was already unsafe because of stalling and the dealer made it structurally unsafe as well... I have opened cases with gm and they aren't doing anything about it. Here this

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, the vehicle was losing motive power with the “Engine Power Reduced” message displayed. The temperature gauge indicated that the engine was overheating. The contact initially had the vehicle towed to the dealer and diagnosed with a defective fuel pump. The dealer replaced the fuel pump, the fuel pump system, and the fuel pump sensor; however, each repair failed to fix the failure. The contact towed the vehicle to AutoNation Chevrolet Pembroke Pines (8600 Pines Blvd, Pembroke Pines, FL 33024) where the vehicle was diagnosed with a defective catalytic converter; however, the part remained on back order. The manufacturer was notified of the failure and a claim was filed. The vehicle remained in the possession of the dealer unrepaired. The failure mileage was approximately 15,000.

Add 1 more victim to the ongoing and growing list of GM owners of vehicles with 5.3/6.2Lmotors with DFM lifter failure. 50 miles after returning from a 500 mile trip from N. Wisconsin fishing trip this motor threw in the towel. Dealer assessment cylinder #6 lifter failure with an extra bonus of damage bad enough to require replacement of entire cylinder head! This motor has 11K. miles on it, and I have had oil changed multiple times as I am old school and don't buy into the whole 7500K. thing. Guess I should have saved my cash for something more fun! Check engine light did not come on till almost 2mi. after vehicle started running badly, flashing check engine light did not come on till I was almost home 15 mi. Had it towed to the dealer on my own dime!

Speed limit 70mph and driving on the highway, suddenly the vehicle began to shake and the engine light came on and the vehicle was making a forced deceleration to 40mph. Other vehicles had to swerve to avoid my vehicle, as I was attempting to pull off the highway safely. "service brake system" alarm also came on. The manual advised when getting this alarm to have the vehicle towed. Once at the dealership this note was on my service papers " Customer stated engine light was on and truck running rough and shaking, review of DTC's showed cylinder misfire on #3, tested showed possible issue with spark plug. Relocated coil to different cylinder to see if issue followed. Misfire still noted on cylinder 3, replaced spark plug and conducted test drive and note misfire still present on #3. Removed valve cover and noted failed lifter on intake valve for cylinder #3. All lifters replaced on left side of engine." The dealership stated that "this is a known problem for the 5.3L V8Ecotec engine, that the lifters FAIL." I am a female, I was traveling alone and had to find tow service and pay up front. Once transported 20miles to the nearest dealership, on a Saturday afternoon, I was stranded at a hotel for 2 days waiting for the dealership to open and check out the vehicle. If this is a "known" problem with this engine, THEY SHOULD BE RECALLED. Now I get to worry when the other side of the engine's lifters will 'fail' so they can be replaced under warranty. This is unacceptable in an almost

Vehicle engine has experienced engine lifter failure at 28,000 miles. Engine began shaking violently, check engine lights flashing, traction control light, and stability control lights all came one while driving on the highway several hours away from home. Vehicle had to be towed by Chevy roadside assistance to the nearest dealership. Chevy dealership inspected and said they have to order new lifters for my engine and it would take several weeks for repair.

The 2021 silverado v8 randomly started making a knocking noise. The steering wheel would shake randomly as I accelerated and stayed above certain speeds. I’m barely able to drive slowly residential speeds at most. If I drive any faster I’m worried for my safety that the car while break down in the middle of a busy road posing a danger to my family and those around me. I’m not sure if this is a lifter issue, or engine issue but it seems to be a widespread issue that I haven’t recurved any recall notice for.

2021 Silverado Trail Boss. Went to the store, came outside started the truck and it showed me ESC Warning and Power Steering Failure Drive with Care notice on the dash. The Steering was very hard to turn. I tried multiple times, and it did not work. I started reading information on line and found out that there are multiple truck owners who had same issue. I saw some information to leave the truck off for 20 - 30 min and try again. I left it off for 30 min and started again. At that time it started fine. I am going to the Chevy dealer because this can also happen while I am driving and it can cause an accident. My truck has only 12k miles.

While driving down the road the engine began to run erratically and several seemingly random errors appeared relating to the parking brake, windshield washer fluid, and engine. The vehicle began shaking violently until stalling out on the road. After bringing the truck to the dealer and waiting for weeks to have it returned I was notified that there had been a lifter failure. Vehicle mileage had been at 12,600 miles at this point.

Truck started having a rough idle and was popping and banging while driving. It was hesitating while driving in traffic and would slowdown and jerk while trying to drive to the dealership. It stalled at red lights multiple times. Once it got to a dealership and they identified it as #4 cylinder lifter was malfunctioning. They have not yet disassembled the engine yet to find out the extent of the damage. This is a known issue with these trucks and GM won’t issue a recall to proactively fix the issue before more damage is done to the motor. Some of which may not show up until after the warranty expires. There was no warning light or check engine light on at anytime. The dealership service department was very surprised by this. Now I’m without my truck for at least 2 weeks with no loaner of voucher for a rental. The truck has less than 19,000 miles on it and has had all regular maintenance done at a dealership.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving approximately 10 MPH, there was an engine misfire and then a knocking sound started coming from the engine. There were no warning lights illuminated. The contact had the vehicle towed to the dealer who stated that there might be a failure with the valve lifters; however, a diagnostic test had not been performed. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 40,000.

"no start" issue. Intermittent no start increased in it's frequency until it wouldn't back in July 2021, it had approx. 9600 miles on it. Had it towed to dealership. They could not recreate problem. I raised hell, and started reading that others had similar problem. A TSB came out that advised tech to install .5 shim. That seemed to have worked until recently late May 2022, have appt. with dealership again. They didn't do a scan the next day to pull a code since one might have shown up at that point. Most likely nothing there now. truck has been driven an additional 10K miles since initial problem and now shows 21400 miles. I can't have this problem every 10K, since soon this will be coming out of my pocket. and it needs a fix as others are having the same problem. GM has had well over a year to sort this out so I'm hoping if it isn't the cam sensor it's something else fairly straight forward. Heading in for service again on 6/15/2022 for same complaint.

2021 Chevy Silverado durmax brought it in three times now for starting issues 2nd time found data module was bad two weeks later brought it back for same issues. Dealer said they can’t find anything wrong I’ve broke down on hwy 5 in. Dangerous spot and know I don’t feel safe driving this.

Can't pull a trailer without the SERVICE TRAILER BRAKE SYSTEM LIGHT coming on a dinging over and over. Had my trailer completely rewired only to find out its a malfunction on my truck not my trailer. My truck is a 2021 Silverado z71 trail boss with low mileage

The contact owned a 2021 Chevrolet Silverado 1500. The contact stated that approximately 35 minutes after parking and turning the vehicle off he was notified that the vehicle had caught on fire. The fire department was called to the scene and extinguished the flames. Upon inspection, it was determined that the fire originated in the engine compartment. A police and fire report was taken at the scene and the vehicle was towed away. During the incident, the vehicle was destroyed. The manufacturer and local dealer were notified of the incident. The failure mileage was 12,000.

I was driving and noticed several loud clunking noises coming from the Engine bay. The truck began to cut out, shake, and misfire. My dash began to flash and state I had a parking brake failure. I had no choice but to be towed. I have just shy of 17,000 miles. The dealership stated I had two lifter and 1 rod failure. They replaced the rod and all lifters on one side of the engine. I took the truck home for one night and it broke down again. The dealership stated it was fixed for a second time. When I picked it up again, I made it 1 mile down the road before the truck had the exact same symptoms with shuddering and misfiring. It is at the dealership for a third time. I was surprised to fin several class action lawsuits now filed against gm concerning the lifter issue. YouTube is full of lifter issue videos. This should be fully investigated and obviously warrants a recall for lifters, rods, and the camshaft.

When I start my Chevy Silverado 1500, three warning lights come on that are telling me that I have brake system failure 43 MPH top speed, Service ESC and Service Trailer Brake system. When I drive, the brakes are very mushy and the truck is very difficult to brake. 20 minutes later after stopping and getting ready to take the truck to the dealer, the brakes worked fine. The dealer couldn't replicate the problem at first, but finally had the issue when they were putting it on the rack to perform improve my tire alignment, so they said they updated the software. The truck brakes worked fine when I left the dealership. The next day (Saturday) I went to start the truck and the same issue happened. I can't take it in as Service is not available on Saturdays so I started looking online. Apparently there are several other owners dealing with this same issue and have been for years. I have read that it might be a variety of things causing this issue, but someone needs to get this resolved ASAP as I have read about some getting into accidents regarding this. My truck is only 16 months old and only has 14,000 miles on it.

My 2021 Chevrolet Silverado started on fire and blew up in my driveway. I had just returned from the store, parked it and went inside. No more than 3 minutes later, my neighbor came running over to tell me my truck was on fire. There were no issues at all while I was driving the vehicle. The township fire department said this is the 4th 2021 Chevrolet Silverado that has burst into flames in the last 6 weeks. They said they all had the 2.7L Turbo engine, as well. The truck is a complete loss. I have contacted the dealership and Chevrolet about the issue and have not heard back yet. The fire started in the engine compartment and quickly raged out of control. The hood and engine disintegrated from the heat. The vehicle was towed away and the insurance adjuster has yet to go out and look at it. If I would've been stuck in traffic on the way home, I would have been in the vehicle and may not be here typing this report right now. It went up that fast. This is a major safety issue that needs to be thoroughly investigated before somebody loses their life. It nearly caught my house on fire, but thankfully there was only minor damage to some garage trim and the driveway is ruined. Please investigate this issue immediately. This was a pretty traumatic experience, to say the least.

On April 29, 2022 between 4:45 - 5:00 pm Eastern, I was dropping off my son at work when I suddenly experienced a variety of Truck Diagnostic Error messages on the front driver display window. In addition my OnStar advanced diagnostic alert system informed me with the following system issues: Engine and Transmission; StabiliTrak stability control; Antilock Brake; and Emissions. At that moment the truck experience a cut in power and slowed down with a knocking sound coming from what seemed under the truck. I slowly proceeded to drop off my son and drove back home and parked the truck. Truck was towed to local Chevy dealer on Friday of that day. A preliminary diagnosis was done Saturday, April 30 suggesting an Engine Lifter issue. On Monday, May 2, 2022, a final diagnosis determined engine lifter failure on one side of engine bank. Vehicle is still under Warranty with 17,400 miles on it.

Intermittent power steering failure.

A squirrel chewed into the fuel line [Hose - GM (84871298), see: https://www.gmpartsdirect.com/oem-parts/gm-hose-84871298). This caused a fuel leak that could be directly observed only while the vehicle was running. On one occasion, however, a small pool of fuel appeared under the vehicle immediately after shut off. This part failure poses a fire and explosion risk. In addition, the wasted gasoline pollutes the atmosphere. The line was replaced at Lynn Layton Chevrolet of Decatur Alabama (invoice 608119). The part was inspected by Lynn Layton Chevrolet as part of that service ticket in order to determine the cause of the leak. To my knowledge, further inspection has not occurred. No warning lamps indicated the failure. The problem was detected by observing the trail of fuel when parking.

Concern: Various check engine lights occurred and vehicle making noise from the motor. Park collision assistance codes, emergency brake engaged code, when it was not on and could not move vehicle. Safety concerns about vehicle completely quitting or braking causing an accident, along with engine issue with only 5,161 miles on the motor of a 2021 Chevrolet Silverado. Cause: Scanned data indicated p0300 stored miss fire #4 cylinder on right side of engine, lifter noisy, push rod #4 intake bent. Correction: Removed intake, exhaust manifold, value cover, cylinder head, right side replaced all lifters, one push rod, related gaskets, reassembled engine.

While driving East on I-24 with my granddaughter. I felt a thump much like hitting a big dog or something in the road. I looked at my 10 year old granddaughter, she was looking at me, she said what was that? I said I don't know, but it happened again in about 1/4 mile down the road. We traveled about another 1/4 mile when the truck started sounding like a machine gun being fired!! My granddaughter started crying as she was scared, I pulled over into the emergency pull off to check my truck. It was running good now and NO ENGINE LIGHT was on. So I continued driving toward Clarksville, TN. although I considered turning back and heading home. I thought maybe it was water in the gas or something. After arriving in Clarksville to pick up my two grandsons we started home. As soon as I got on I-24 west the truck started the same thing again. Felt like we hit a big dog and then started sounding like a machine gun being fired. This time the ENGINE LIGHT DID come on. I was afraid the truck was going to quit running and there I was with 3 grandkids on a very busy I-24!! I contacted Patroit Chevrolet where I purchased the truck at. They told me it would be 6 weeks before they could look at my truck!!!! I hung up but called back as I was afraid that I couldn't make it home, the truck was running bad!! They found that it had dropped a lifter, it had only about 6,300 miles on it!!! They had it for about 3 weeks. Now, I find out that GM has had a lot of problems with these motors, "A LOT of

There is a massive shudder that sounds like the whole dash could come loose. feels and sounds like rumble strips and off road driving mixed all together. It happens at all speeds and when rpms are steady around 1200-1400.

I have a 2021 Silverado 6.2 being repaired for failed lifters. I see this is a common trend and can cause hazards when pulling over for a faulty motor. 10 speed Transmission downshifts from 2 to 1 harsh with rpms jumping up causing for me to apply more brake pressure to stop. I have had a few incidents when I get close to the vehicle in front coming to a stop. I have taken vehicle to dealer for issue and they couldn’t replicate issues. Check engine light has popped up once or twice but never stayed on long enough to throw a code.

Engine valve lifter failure at 20,000 miles; engine hesitation and power loss. Error to parking brake and to electronic stability control. Chevrolet to replace damaged lifter but refused to replace both banks of defective lifters. As a result of dysfunction I was stranded 1200 miles from home and have been waiting 2 weeks for repair. Still 1200 miles from home with 2 kayaks, 2 bikes etc.

Engine lifter failure, excessive engine noise, loss of power and responsiveness, strange sounds from engine and runs very rough especially during acceleration. Multiple warning lights associated with the valve failure. Cruise control no longer works.

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.

While driving the vehicle on a snow covered road the check engine light, abs light, esc light and parking brake light all came on. The vehicle also lost braking power. Took to the dealer. They told me it was a brake control module. If you do some research this is a on going thing since 2018. But they still continue to put this part in the trucks. On top of all of that they don't have a replacement part for the truck. Now the truck is going to sit at the dealer for one to two months. I am now paying on a truck that I can't drive to work and no loaners available. my question is why are they aloud to still put these parts in a truck. How do I know if they fix it if the problem wont happen again. If it does happen i hope my family and any one else is not in the way of my truck that I am unable to stop.

Every so ofter I get an audible and visual alert telling me to Service Seat Safety Restraint System as well as the airbag light on the dashboard. This lastest incident is probably the 8th time it has happened since Ive brought the truck new

At 7000miles truck had sudden engine failure, pulled to side of road and had towed. Dealership said it has a conmonly occuring failure of valve lifters causing bent pushrods.

Lifters in the engine failed causing the truck to sputter and shake going down the highway. Barely could hold it in the road. Truck wanted to stall out while driving. Truck was fixed and made it 30 miles before the same thing happened again. Chevrolet has dropped the ball and needs to be held accountable for this problem before someone gets hurt or killed.
