2020 CHEVROLET SILVERADO 1500 Recalls, Complaints & Safety

While driving in early morning while still dark outside, loud noise occurred with decreased acceleration on interstate. This placed my life and the lives of others at risk due to not being able to accelerate out of traffic coming behind me. Vehicle Taken to chevy dealership who advised lifter had broke and damaged camshaft. This occurred out of nowhere without any warning or lights on dash

I was driving at approximately 75 to 80MPH on the highway when my engine shutoff and the vehicle died while driving it. I was able to coast to the side of the road but had to cross two lanes to the left to do so while weaving in traffic to get to the shoulder of the road. There was no warning of any kind that would have made me aware of an issue prior to this happening. I was unable to get the vehicle started again and had to have it towed to my local dealership Hendricks Chevrolet in Columbia, SC. That occured on Saturday March 14th 2026, that Monday, I have had all regular and scheduled maintenance done to my vehicle either on time or prior to the recommended time including oil changes and the like. I went to the dealership and they told me that the engine had seized up and that this was a very well documented and common issue with the 6.2L L87 V8 Engine dating back to 2019 but that GM had only issued recalls on the 2021 - 2024 years to correct the issue. I asked the Service manager at Hendricks Chevrolet to file for a Goodwill Coverage request on my behalf to cover the repairs of the engine and he refused and stated that I had to do so through GM customer service line. I have done so since and my case number with GM is 92108267. My vehicle is currently at the dealership awaiting the go ahead from GM to replace the engine. I have an extended warranty on my vehicle that goes to 120,000 miles and the issue occured at 114,113 miles. This is a very well documented case where the engine connecting rod bearings fail due to oil starvation that leads to engine seizure.

Unexplained complete engine failure. Engine seized, no warnings, on gauges or lights. Dealership repair shop indicates engine has seized up.

Started to work first thing in the morning, the truck felt sluggish-like a lack of power. I drove about a mile to turn around and head back home, something was obviously wrong. When I got out of the truck there was a smell like something was hot and the wheels were extremely hot. I realized the lack of power was due to the brakes being locked. The parking brake was not engaged. After calling the local dealer for an appointment, I had to get the truck towed. Now the 2nd day at the dealer with no diagnosis, no service codes. The truck has approximately 77,000 miles with the original brakes from the factory and have never had to be replaced. The vehicle data display shows 42% of brake wear remaining.

The engine started making a lot of knocking sounds and it has no oil pressure now. The shop says the engine needs to be replaced.

Well taken care of 2020 trailboss upper control arm completely failed driving down the interstate with family in the truck. Suspect defect from ball joints. Only 68k miles. No warnings. Tire fell into suspension causing thousands in damage. Had to be towed. At high speed we could've all been killed. Seen multiple reports online of similar ball joint/ control arm failures. This needs to be addressed ASAP! Very dangerous.

Crash

Intermittent issue where info says brake failure/steering assist not working/limited speed to 43 mph. Very dangerous if you’re on the interstate. Becomes hard to steer, brakes don’t work, brakes start burning up. Have to carry tools with me to reset ecm. Very common problem with Silverado with 5.3 gas engine. Chevy needs to fix this issue before someone gets killed. I would give them my truck back if I could.

I replaced the fluid in my truck at 142k miles and when I went through all of the gears and checked for drips or leaking it was fine on that front and then I went to reverse and all of the gears were neural and only revved and when I went into neutral it started driving forward like it was the drive gear.

REGULAR OIL CHANGES AT 50% OIL LIFE WITH RECOMMENDED MOBIL1 OIL & ACDELCO OIL FILTER.

I have 2020 Chevy 1500 with L87 engines on it. We have the exact same issues that the 2021 1500 recall is having. Loses power, noisy engine when at start. Paradise Chevrolet in Temecula told me that they were going to replace the engine per GM but then GM only auth the repair. 8 barring kits, 8 rings 8 piston kits lot of bolts and gastkit and seals. Talked to GM every tho it’s the same engine they won’t replace it since not on recall. Don’t understand how the same engine in a car one year before the recall. I have all the paperwork video of the noise pictures of the Pistons. I failed from the dealer. Had to get the truck towed to the dealer cause the car wouldn’t turn on and all this happened with only 68,833 miles.

Internal oil consumption. With no oil puddled or spattered under the vehicle at time of purchase from a dealership or since then, a dealer certified vehicle with AFM at 153 miles from leaving the dealer the oil was non-existant on the dipstick. This directly indicates a TSB, Techical Service Bulletin involving the cause of failed lifters causing internal oil consumption and damage to lifters, cam shaft, push rods, rings and possibly more. This is a common result of the Active Fuel Management system which shuts off some of the cylinders for fuel economy for Chevrolet V6 and V8 engines. The problem was reported to the dealer by me imediately after the oil check at 153 miles and then towed to the dealer. As this is considered a catastrophic amount of oil loss, the vehicle could've been rendered inoperatable during operation in traffic and been a servere safty hazard. The dealer after initial inspection sent me a message that they think the problem is an undetectable small leak so they put some dye in the oil to check it. Which evades the actual internal consumption problem of 1.5 to 2 or more quarts of oil lost in just 153 miles by that ratio that would amount to 13 quarts per 1,000 miles. And helps them stall for time, to try to run out the very short 3 month/3000 mile drivetrain warranty. There was noticable erratic engine performance and some shudder but that shudder may have come from the transmission. The odometer read was 115690 at purchase and 115843 when towed=153 miles driven from when the certified inspection was performed for a loss of 1.5 to 2 quarts that I know of, it could have been much more oil missing. A suddenly inoperatable vehicle in town at intersections or on the highway at high speeds could be deadly for myself or others in traffic. I took and have videos of checking the dipstick to show it dry but it's an mp4 file which I don't see a place to upload it here. Available upon request.

The first thing was the whole engine shut itself off going 40mph and slowing down thankfully after I turned the truck off and back on it started right back up then I was driving 75 on the highway a couple days later and the whole truck started to shake as check engine lights came on and flash and the engine started to tick and groan. We pulled the spark plugs and cylinder 5 had clearly not been firing as it was designed to and then later found that the entirety of cylinder 5 had basically shredded itself from the inside out. Now my truck is waiting at the shop for a new engine. Both cases I had my kids in the car trying to get home.

My entire engine and the right bank lifters failed. Thankfully, these issues didn't fail until my truck was parked in my garage. No warning lamps did not trigger until these issues started. There was no warning. I have been having engine issues with this truck dating back to 2022. I will include all documents showing the issues I've had in the past 3 years. I was informed by the dealer that this is a known issue with this year and model of truck and even they were surprised that GM hasn't issued a recall. The vehicle has been inspected by the dealership only.

During an extreme cold event in Interior Alaska (–44°F), the vehicle experienced a sudden emissions‑system failure that triggered an EPA‑mandated Limp Mode, limiting the vehicle to 5 MPH on high‑speed highways. This created an immediate life‑safety hazard because it was impossible to maintain a safe speed or exit the roadway due to snow berms. Prior to the failure, the vehicle displayed “Service Emission System” warnings and multiple DTCs related to the reductant heaters and sensors. A dealership technician later confirmed a “burnt pin” at the reductant pump connector, consistent with thermal‑electrical overload. This failure mode matches GM’s TSB 21‑NA‑006, describing connector overheating in cold climates. After the repair, the vehicle continued to exhibit safety‑critical symptoms, including harsh downshifts, delayed engagement, and jerking during deceleration, consistent with Recall 26V083000 (rear‑wheel lock‑up risk). The vehicle also continues to emit an electrical burning odor in cold temperatures, consistent with Recall N192206310 (block‑heater fire risk). The only GM dealership in the region issued a “Termination of Business Relationship,” preventing access to all recall and warranty repairs. This has created a 321‑mile “Service Desert,” making it impossible to obtain federally mandated recall remedies. The vehicle remains unsafe to operate due to unresolved transmission, electrical, and propulsion issues.

Brakes lock up on vehicle while driving Must turn vehicle off and restart several times to disengage brakes. This has happened twice in the last 8 weeks, very concerning as we cannot use our travel trailer as we do not trust this not reoccurring. Chevy dealership says there is a recall on this issue but not on my truck?. But they say it is THAT problem

In several situations, I have lost partial or complete power steering ability. Once, while driving, I recieved a SERVICE ESC message and steering became quite difficult. Another time, power steering was completely gone, making steering impossible, although every other aspect of the vehicle operated normally. In both instances, there was no clear issue and after some time with the vehicle parked and off, it would return to normal. Possible loss of power steering unexpectedly is a serious concern at this point.

Lifter failure in 2020 Silverado 5.3 engine causing loss of power while driving.

Engine failed on interstate while pulling my RV. Almost had a bad wreck due to this happening. This is the known 6.2L engine failure issues. Had to have motor replaced by Chevrolet and had to pay out of my own pocket.

We own a 2020 Silverado with a 6.2L L87 engine… I am aware of open investigation # EA25007… Our vehicle had sudden engine failure.. no prior warning lamps before failure. (Our vehicle had no open recalls) Once vehicle engine failed left us with no power… had to coast vehicle to a stop. Will not restart. Verified proper oil level on dipstick so vehicle was not low on oil. Had to tow vehicle to shop .. retrieved code P0016 - crankshaft position Oil pan was removed and found bearing material as mentioned by GM issued recall 25V-274. Verified oil pickup tube was not clogged. All symptoms explained by 25V-274, we’ve experienced.

On September 27, 2025 while driving to my nieces soccer game my 2020 Silverado Traill Boss LT started losing power while driving. I was at a Red light when I felt the truck not properly responding to me pushing the gas pedal once it turned green. It slowly started accelerating and then with all the lights still illuminated on the dash, the truck completely stopped working with No response to the gas pedal. I had to let the truck coast forward while driving through an intersection. Thank God there was not that much traffic behind me and any cross traffic. I managed to pull the truck over stuck on the side of the road. My wife had to get a ride from a family member to reach the destination while I had to call a tow truck and have it towed home. Ironically, I believe the truck had just got out of Warranty, what a complete waste of thousands of dollars including the warranty that is always useless. I did not reach out to the dealership because I knew it was going to cost me an arm and a leg just for a diagnostic only for them not to find a problem. There was No Warning Light Flashing to notify me that my truck was taking a dump or any error code of any sort for a diagnostic to pinpoint the issue. I am surprised this has not turned into a Class Action Lawsuit (not yet anyways). My Father made me a Chevrolet person but with all the recent Engine/Powertrain problems with General Motors. I always believed the slogan "The longest lasting dependable trucks on the road". Tanks to YouTuber "@Donslife" for keeping the Public informed of all the latest updates with all these issues. This might be my last Chevrolet ever unless they could fix these issues and take some type of customer reimbursement/assurance/future or current incentives.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that immediately after leaving the dealer after the vehicle was purchased, the check engine warning light illuminated. Several days later, there was a loud knocking sound coming from the engine before the engine failed. The contact referenced NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The vehicle was taken to a dealer and an independent mechanic, but was not repaired. The vehicle had experienced catastrophic engine failure. The check engine warning light was displayed, and audible knocking was coming from the engine. The manufacturer was notified of the failure. The failure mileage was 153,000.

The vehicle experienced a transmission control malfunction related to a transmission solenoid (diagnostic code P0776). The transmission exhibited abnormal shifting behavior and drivability issues, prompting a warning indicator and dealer inspection. The condition affects the powertrain and could impair safe operation of the vehicle, particularly if shifting becomes unpredictable or the transmission enters a reduced-function mode while driving. The issue was confirmed by an authorized Chevrolet dealership, and the vehicle was subsequently deemed inoperable pending replacement of the required transmission solenoid component. The vehicle was inspected by General Motors on November 3, 2025, at which time GM confirmed that the required part was on national backorder with no immediate availability. The vehicle remains unavailable for use due solely to the lack of this GM-supplied component. A warning indicator and drivability symptoms were present prior to removal from service. The component is currently retained by the servicing dealer and is available for inspection upon request. General Motors has advised that this component is subject to a widespread national backorder affecting numerous vehicles, resulting in extended periods where affected vehicles cannot be repaired or safely returned to service.
