Page 8 of 10: complaints 191 to 220 of 272, newest first, as owners wrote them.
Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.
• lifters, cam, manifold; failed. no warning, nothing just seized up • left with no power, braking system locked up. • yes; occurred January 2024. everything replaced. received back in March 2024, 10k miles later transmission begins shuttering. January 2025 lifters failed again. • yes it has been evaluated by dealership. they just throw their hands up. • no warning lights prior, driving in winter 30-40degrees weather. brakes seized, truck haulted and upon attempting to accelerate the motor was knocking and done for. January 13th. 11:51AM 2024
I bought this truck with 72,000 miles on it I put about 3,000 miles on it and the engine seized. I had my mechanic inspect it and he confirmed the motor is seized. There was absolutely no warning is just stopped running and left me on the side of the road
Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me.
Vehicle would not start, had it towed to a shop and they said the engine locked up. After tearing motor down the main bearing was scored and there were metal scratches.
Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won’t acknowledge.
While driving home truck began to misfire and drop in RPM’s. Service ESC and Service Parking Brake popped up on my notification system. My Engine light was blinking and my Traction light was on. While i was turning into my street to get home, my engine shut off. The steering wheel and brakes became hard as the motor wasn't powering them. I was able to turn it on and get it into my drive way. Afterwards when trying to turn it on, it would turn on and shut off immediately. Chevy replaces a fuel pump module for a second time(recall), added a new starter and battery. After Three months they then told me I need a new engine because it has locked itself up. I purchased the vehicle with 32,000 miles and It currently has 49,000 miles. Chevrolet are not going to warranty me a new engine because i do my own oil changes (which were 2). Had this happened on the highway or in traffic, i would've been at a high risk of causing an accident considering power steering and brake system was not working properly.
I was driving on a wet Road with more than an inch of water on the road and all of a sudden my engine blew up I took it to the Chevrolet dealer and they told me that water got in the engine and it was my fault I feel that the engine failed and should not have
While driving down road at around 60mph 6.2L engine started to make loud knocking noise and shaking violently while loosing all power. Truck had 79,797 miles on it at the time with all oil changes and service done at GM dealership. After having GM dealership diagnose truck, it was determined to have a spun rod bearing, causing multiple other engine components to fail. Truck was not under factory warranty and was quoted $12,200 to replace. There were no warning lights or any known issues until this incident.
Had the top of the motor rebuilt twice, first the left side, then the right side. Then GM replaced the motor out of warranty. A year and a half later the rear main seal blew and the seal was all mushroomed and out of shape.
Excessive Oil consumption from new and lifter failure at 116,000 miles

Driving at the speed limit 65-70 miles ph my truck started to slow in speed the tire sensor came on then the truck began to smoke and the brakes locked up at a high speed, lucky for me there was no one behind me. I was able to limp to a safe spot and park the truck would not MOVE at all..After an hour I tried to move it again it would not go into drive. Had to tow it to the dealership..$$$$ later they say well we can't recreate the problem so it's drivable. I drive 2 blocks and it stops in traffic almost causing a collision. Had it towed home and for 3 moths now it has sat while I have to continue paying payments on a NON running 2020 with only 102 thousand miles on it this is CRIMINAL!!!!!!!!!!!!!!!!!!!!! was told possible $62k to repair but no guarantee it would stay fixed!!!!!!!!!!

Main bearing on crankshaft when out
My vehicle only has 20k miles on it and I’m already replacing a lifter and camshaft due to the active fuel management system. At the time of taking my truck in there are three other trucks for the same issue. This is known issue at my dealership and this time I’m covered under warranty, but they told me to be prepared to repair this again and next time will be out of warranty and around 5k to repair.
Engine light came on, service park brake light came on, truck started jumping and misfiring, code says cylinder 5 misfire.

On September 21, 2024 my Chevy 1500 series truck in the year was 2020. It was made caught on fire white driving it. We were returning from a trip pulling a trailer from Kentucky to Mansfield Ohio when we were on the highway. The transmission light/panel came across and said transmission need to engine idle. I drove it about 3 miles and pulled off on an exit at a gas station and did what it said after proximately 10 minutes. The message went off and cleared. we resume going home on our trip and we are 14 miles on the highway then we got off on our exit there’s no lights or no problems with the vehicle. I dropped off the first passenger and Lexington, Ohio, and then the second passenger lived about a half mile away , this time kept unloading their equipment. From Lexington to my home in Mansfield, Ohio the other passenger I was talking about the light transmission was weird and might’ve been just a sensor. As we pulled onto Home road all the panel lights started flashing and then a message came across and said engine is shutting down. I put in park off the engine, we exit the vehicle and smoke was coming out from underneath the truck. I reached into the center council to grab the cell phones and had faster call 911 and when I reached back into the truck were coming out from underneath the hood. I notified General Motors on September 23 and have been battling them to get an inspection done. after several months, they have finally agreed with insurance company on terms to investigate what caused the fire. That inspection is to Take Pl., December 4, 2024. I have recently just seen the recall article on GMC that came out on November 13. My truck is listed in the article as far as your make and model. This was a transmission problem that GM is trying to ignore and should be held accountable. Have video of when it caught on fire and how quickly it burned up.
Shifting problems. Transmission feels like it is going to fall out. I have taken it in several times to be fixed and my Chevy dealer can not figure it out. Problem never fixed.
Engine start to make noise while driving Took my truck to a auto shop Mechanic said that it is a fabric defective engine
The truck caught on fire while I was returning from a trip out of state and then it appears it came from underneath either the transmission the engine or electrical. While returning home a message came on the panel on the highway, saying transmission, hot idle run I pulled off and did this and after about 15 minutes, the message light went off and I pursued Coming home nothing was wrong with the truck. After I dropped off to the passengers, I was on the way home and turned on home road and the message came on that says truck powering down all the lights came on the dashboard. I put the truck in park and shut the engine off had a manly open the doors and got out and smoke was rolling from underneath the truck. I grabbed the cell phones and told my passenger to call 911. I went back into the center of the cab to grab something out of the center council and flames came from underneath the hood up the glass of the windshield right in the middle of the truck. Backed away I called 911 again. Troy fire department responded in about six minutes. The truck was engulfed and gone. Ohio state patrol give me a claim number of [XXX] the instant [XXX].

I'm beginning to have similar problems with the 6.2 ecotec3 engine that gm has known problems and hasn't recalled them. Dealer indicates metal shavings from the main motor bearings. Just like others I will experience a total motor failure at anytime. This will be catastrophic if motor fails and shuts down. I fear I will be rear-ended or not be able to get out of harms way. This has happened to many with the same motor. Why would there not be a safety recall on a known safety issue. Others affected have been injured even killed because there vehicle just stopped in the middle of a roadway. I currently fear for my families safety and cannot simply opt out of a vehicle with only 18,000 and thousands invested. Instead it sits waiting for the right thing to be done. To be repaired to safely use. Thank you kindly.
Total engine replacement at 62k. The junk lifter system government regulation has compromised our Vehicles. Active fuel management systems are used expensive trash changes to our American motors that generate extreme hardship for single vehicle owners.
Vehicle is burning oil. I drove 300 miles and had a low oil message pop up. Vehicle still had 50% oil life left.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 35 MPH, there was an abnormal sound from the engine compartment. The contact stated that the check engine warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the serpentine belt needed to be replaced. The vehicle was repaired. The contact stated that the failure recurred, and the vehicle was taken back to the same dealer and was repaired. The contact was concerned that the serpentine belt had failed twice. The manufacturer was informed of the failure. The failure mileage was approximately 3,500.
I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.
Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that i could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given i could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As i was getting on the highway, the truck started to jerk like it wanted to stop as i was speeding up, i was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service ESC" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day i scheduled an appointment with a mechanic in town who checked it and said i would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9K.I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0P50D and P0304.He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60K miles and I have 80K now.
I have a 3.0 LTRe Dura Max issue is if the (Timing Belt ) or actually the oil pump drive belt breaks the engine will lose power if this happens in the middle of an intersection or major highway you will loose total power
