. I bought this truck for my husband as a birthday present & it has been a nightmare. My husband is a [XXX] & I wanted a vehicle that he would be comfortable in to take him to his numerous medical appointments. The first indication was the check engine light came on. I took to to O'Reillys & they scanned the vehicle & no issue was detected. I then had several instances where the vehicle would not start & one instance when it would not go into reverse & the truck was making a noise from the underbody. The windshield washer unit also was not working. I then took it back to the Ford dealership where it was purchased. They ran a scan at the dealership & said there was nothing wrong. They then indicated that I should take it to a Chevy dealer which I did. They stated that Chevy has a special scan that the previous scans cannot access. I documented all the issues and the Chevy dealership found 8 issues including the transmission, holes in the struts, software issues, washer pump, grille shutter & loose battery cables. The Ford dealership agreed to fix the struts & the washer pump as well as the diagnostic testing. I thought we were going to be able to resolve the transmission and the grille shutter issue but that has not happened. The defective grille shutter is what is activating the check engine light. The Ford dealership charged me for fixing the battery cables and yet they were needed to be done again. They also told me that the grille shutter was not necessary as I could drive with it but I would never know when I had an actual problem. They wanted to replace the torque converter. I submitted a request to Carvana & they offered me 5,000 and I paid double that plus. I don't feel safe driving the vehicle and GM is well aware of the issues with this make and Model. Let's not wait until someone is killed or hurt before action is taken. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while in reverse(R), the back over prevention camera displayed a blue screen with the message “Camera Service Required” displayed. The failure was intermittent at first but became a permanent failure. The sensor for the hood latch displayed the message that the hood was not closed, even though the hood was securely closed. The contact stated that the remote starter failed due to the hood latch sensor failure. The contact was unsure if the two failures were related. The dealer was contacted, and it was confirmed that the failures were not covered under warranty. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 56,000.
My 2019 truck with 50k miles on it, broke down and nearly caused an accident. The safety recall for the wiring harness chafing was not assigned to my VIN. I had vehicle towed to find out my loss of power and 17 error codes were due to the wires rubbing due to improperly installed by the dealer per this the federal safety agency. I called the 1800 number for Chevy and they told me my VIN wasn’t “Picked” to be part of this recall. I asked why, my vehicle did exactly what recall said. They said sorry we can’t do anything. I could have died the way the truck acted. I need a complaint filed and assistance having the dealer add my VIN to this recall. Any assistance will be appreciated.
Vehicle power steering went out while driving as I almost crashed through the corner. My anti-skid light came on on the dash along with a message saying service power steering drive with care and a message saying service ESC. Upon further investigation, it appears the ground strap connecting the frame to the passenger side wheel well is corroded camming electrical problems with the power steering, etc. Apparently my Vin number does not qualify for replacement on my 2019 truck even though it’s still in their warranty Chevy should replace these straps for free. The dealer wants to charge $300 for a diagnostic fee in around $300 for another repair. However mine is under warranty, but I feel like I should not have to pay a diagnostic fee. It should be covered as a recall. I have attached pictures of the codes from the dealership computer.
I’d like to report a serious, ongoing safety concern with my 2019 Chevrolet Silverado (5.3 V8 53,028 mi) since Dec 2025. Over the last 4 months, I have experienced at least 20 engine failures/loss of power, with no engine light illuminated after restarting truck. These failures result in a complete loss of power, including steering and braking, posing a significant risk of a crash. Chevy said it would be hard to diagnose with no engine warning light on. Feb 24th, engine failure, warning light stayed on and towed truck to Chevy. Truck on standby, repaired Mar 10th, replacing 2 oxygen sensors per Diagnostics. Picked it up on March 11th, but engine shutdown again the same day and 4 additional failures while driving in my neighborhood, making the truck undrivable. I reached out to Chevy service supervisor, Juliana, but have received no response for the last 10 days. I urge the federal safety agency to investigate this defect as it poses a severe safety risk. Thank you for your urgent attention.
Oil cooler lines are leaking oil. A known GM issue with many owner complaints online. Transmission issues. Motor issues. electrical issues. brake issues. These particular trucks have many issues and nobody is taking responsibility for the issues.
Odometer Fraud. The contact purchased a 2019 Chevrolet Silverado 1500. The contact stated that upon arriving to the DMV parking lot to register the vehicle, the contact compared the VIN the dealer had initially provided prior to the purchase, to the VIN listed on the title and on the vehicle. The contact discovered that there was a VIN discrepancy. The contact contacted an independent mechanic retrieved a Carfax Report of the VIN listed on the title and informed the contact that the actual vehicle mileage was 182,041. The vehicle was a private sale. At the time of the purchase, the vehicle mileage was 72,409; however, the Carfax Report confirmed that the actual mileage was 182,041. The seller was contacted but failed to respond and had ended communications with the contact.
My 2019 Chevrolet Silverado has experienced repeated engine issues, including a confirmed timing chain failure. The vehicle has been taken in for repairs approximately 6–7 times for the same or related engine problems. Most concerning, the vehicle has stalled while driving, creating a serious safety hazard. Loss of power while in motion puts me and others at risk of an accident. Despite multiple repair attempts, the issue has not been permanently resolved. The timing chain failure is a major engine defect and not expected for a vehicle of this age and mileage. I am filing this complaint due to the safety risk associated with engine stalling and failure.
My Chevrolet Silverado has unresolved Electronic Stability Control (ESC) issues after recall reprogramming was performed twice under my VIN. The vehicle is shaking, hesitating, experiencing reduced acceleration, and feels like it may stall while driving. The truck is unsafe to operate. Dealer diagnosis is scheduled. GM Customer Care advised me to take it to the dealership before escalation. This is a loss-of-propulsion safety concern combined with unresolved ESC recall repairs. Vehicle has approximately 130,000 miles. Symptoms include shaking, hesitation, near-stall, and power loss while driving. ESC recall previously performed and still not resolved. Vehicle is drivable but unsafe. Blinking Engine light code cylinder 1 misfire. All ESC lights on parking brake, traction control.
Transmission/ignition. Can not lock vehicle and battery will die. When turning the ignition to off, dash message 'shift to park' appears. Must turn ignition on and off repeatedly to get it to go out. Dealership tried tightening a plug but it did not work.
Rear window defrosted heated up so hi my window exploded
Unknown, ESC , traction control, service brake. The truck stop and those 2 codes shows and is on but doesn’t it move
I own a 2019 Chevrolet Silverado 1500. While driving 35 MPH entering the flow of traffic, the vehicle lost power with the engine misfiring. The messages "Service Parking Brake" and "Service ESC" were displayed. The check engine warning light was also illuminated. I drove to the nearest dealership the vehicle was diagnosed that cylinder #5 lifters had collapsed. The dealer informed me that the cylinder lifters needed to be replaced. Additionally, the camshaft would be replaced as necessary. The vehicle was being repaired. The manufacturer will be notified of the failure. The failure mileage was approximately 88,000. and I was informed that my service contract had expired less than 2 months ago
As I was driving the vehicle it seems to be hesitating or jerking and when I tried to start it,it would say put your foot on the brakes to start,but my foot was on the pedal and it was slow starting.Days later the engine light came on,took it to the dealership and they told me it was a problem with the brake system.I bought the vehicle brand new,only 41,000 miles,on it now,warranty went out in June of this year.I very rarely drives it and now they saying its a 4,000 job to get it fixed.
My truck for several months now has been having an issue with power steering, gets a service vision system where at time I get no back up camera and a server trailer brake system. While doing research I've found dozens of posts and videos of issues with 2 ground straps on the vehicle thaylt have affected all 3 or these issues I am dealing with. The ground straps are under the truck near the right wheel well and are basically out in the open not protected wires. I live up north in New York and these wires will corroded overtime especially dealing with salt, snow etc. It is a known issue that a TSB has been put out. I called GM to speak with them of this issue and was told that I haven't bring it to a dealership to look at where I would have to pay a diagnostic fee. I would also possibly be responsible for the repair itself. This issie with the ground straps should be a safety recall especially due to the fact it affects power steering. This has caused my vehicle to at times be unsafe to drive when hard to turn. Thos can cause a serious accidents. The fix is so easy and is a huge engineering flaw with where these wires were placed and not protected. Im asking you to put out a recall so individuals like me can get this issie fixed with no costs to the customer. Not fair for us to foot the bill for a known SAFETY issue. This issue happens everyday. Not sure of exact start date that this is making me choose.
The back windshield on my Silverado leaks water every time it rains causing the back window to smell of smoke like electrical burning. It also creates a visibility issue out the back window when I've called three different dealerships in the area and each one of them say it is a known issue with this vehicle and it's going to cost almost $3,000 to fix. I have contacted GMC only for them to say that I needed to contact this department I feel like this is a safety issue that GMC should have to help their customers with not just be like oh well your truck may or may not be on fire while it rains
When attempting to park the truck and shut the engine off, a message appears on the dash stating that I should "shift to park". I have already made the shift to park but the system will not allow the electrical system to shut down. A loud beeping begins, door locks remain open and inoperable, the vehicle is then unsecurable and the ignition remains open/on which in time will run the battery down. Disconnection from the battery will stop the drain on the battery for this particular event but will not cure the problem nor erase data that has sometime worked on complex computer controlled devices. I refuse to allow my wife to take the vehicle to park at any location for fear of her safety to secure or lock the vehicle and, in the event she would have to vacate the vehicle it would increase the possibility of theft of the truck. GM has recalled other makes of their products for the same problems which I understand was also reported to the federal safety agency and has also suffered litigation in the form of class action suits which was won by consumers in the states of Tennessee and Ohio. After consulting the dealership with the complaint, I was instructed that GM has not issued a recall for these trucks which experience the same problem as those they were required to recall and repair. The costs for such repair by the consumer is unreasonable and unwarranted by reasons that this is a manufacturing AND certainly a SAFETY problem for the consumer. Their disregard for safety and quality control has been demonstrated continually as research in this matter and other complaints of GM problems are and continue to be numerous. This vehicle is IS out of the normal warranty range. However, just as the problem with the brakes that suddenly failed just after the warranty expired on this vehicle which was also a major safety problem, extensive testing of GM safety performance is not a priority but rather they ship it out the door to consumers and just see what happens. Thanks you for your time. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM O

Truck goes into limp mode several times… fuses pop when it does..it does it when I drive or hit any slight bump
I went to drive my truck and it would start but I got a “ service power steering no assist “, service rear vision camera, service trailer brake system. Then it wouldn’t start and got the “ lost communication with fuel pump control module, back up camera was flashing in and out and license plate lights would flash with turn signal on.
I have a 2019 Chevrolet Silverado 1500 LTZ. 5.3 Ecotrac 8 transmission with 89,000 miles. I bought it used and have had it 12 months, but only drove it 9 before it malfunctioned causing severe electrical & mechanical problems. I was driving the truck when the EPB, service engine, stabilitrac, ECBM warning lights came on, also driving over 43 miles an hour could cause a crash due brake failure This caused the emissions. transmission, & throttle to shut down Truck would not shift out of low gear. It would shift to park but did not recognize it was in park which kept the accessory on running down the battery, the tail gate would not open, and the information system shut down. I got sick and was in the hospital for 5 weeks, the truck was vandalized. The body repair shop took it to the chevrolet dealership in long beach to have it inspected. I did not tell them the vehicle had malfunctioned, throwing code U0101 and another code. I wanted the dealer to find the problem, the truck had not been driven since it was parked from the malfunction. All they came back with was I had a burnt cylinder and would be 9000 to fix due to maintenance, we maintained this truck changing the oil every 3000 miles with Castoroil synthetic oil, regularly checking and maintaining transmission, brake , all-fluids. Supposedly they ran a diagnostic, if they did they would have found these warnings and that main code U0101 would have showed up. When it happened Onstar ran the diagnostic and told me to take it immediately to a dealership. That dash should have lit up like a christmas tree that’s how many light were going off. The dealership never said a thing about these lights. Now i’ve read where Chevy had a problem with the EPB and only put them on this model from 2019 to 2022 because of this. I found on other sites recalls that included what happened to my truck, but not in your web sight. There was major design and manufacturing flaw with this model and year. I’ve read complaints on this.
The vehicle began knocking on the freeway and experienced a loss of power. It caused warning lights for the Electronic Traction Control and parking break system to light up.
It’s been draining the battery every couple of days,sometimes the screen won’t turn off it just stays on but black it won’t even play the radio the tailgate won’t open most of the time the dashboard is been over heating it gets extremely hot I tough it was just Texas weather but on winter days was hotter than normal when I put it in park it won’t it keeps beeping and showing a message to put packing on sometimes you can hear a very thin noise coming from the dashboard ..transmission vibrates over 50-60 mph
