What 346 owners told NHTSA about the 2023 Chevrolet Silverado 1500 Ltd

Vehicle had recall for L87 engine performed, resulting in a change to 0W-40 motor oil and a new fill cap. Approximately one week later, the engine failed completely, with evidence of significant bearing wear in the used oil analysis I had performed. The engine has since been replaced under warranty. There was no prior warning to the failure, except for unusual noises during the failure.

Loss of engine propulsion while traveling down a highway towing a #5000 trailer at 65 mph. Less than five miles before the failure the vehicle experienced a momentary downshift of the transmission such as you would experience while climbing a hill or extreme headwind. No warning lights were present at that time or at any time prior to engine shutdown. Upon failure panel indicated "Press Engine Start" and transmission indicated "Park" though we were rolling/coasting at over 60 mph. Realizing that we had lost propulsion I guided the vehicle to the shoulder and stopped. Solid check engine light on at this time. Depressing the "Start" button while stopped would not start or crank over the engine. Boost box would not crank engine, slight noise from starter as if unable to turn engine over. Called tow truck, Seewald's Towing in St. Ignace, MI. Towed to nearest Chevrolet dealer Wheeler Motors Cheboygan, MI.

My 2023 Chevrolet Silverado 1500 has experienced two separate major drivetrain failures — complete transmission and turbo replacements — within two years of purchase, both during peak use months. The second repair kept the vehicle in service for nine months with no ETA provided until escalation. The repeated failures have rendered the vehicle frequently unusable, caused significant business loss, and represent more than normal wear. Documentation of repairs and dates is attached.

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got my truck back, it was covered in dirt, oil on the exterior paint and inside the engine bay. The dealership didnt update my truck as requested and didnt touch my leaf springs at all. They said it would take 5-7 weeks to get new ones, but I needed my vehicle back which is anitated on the work order. Thr parts were all delivered 45 days after it sat there and my truck wasn't worked on until day 94 as advised by the service advisor, as the mechanic would get to it after his next vehicle. I asked how is my truck not priority sitting there for 93 days at the time. GM customer service has submitted my vehicle payment reimbursement as I paid 4 payments while having no vehicle or loaner. $44 a day for a rental at my duty station would cost me considerable amount of my own money to cover the rest and would not be a similar vehicle to my truck, as ot would be a small car. JN Chevrolet in Honolulu did not communicate when it failed the test for 14 days, I had to call them, they gave zero updates for 2 months, I had to call GM customer service. I only received 4 calls in total from the dealership when I asked to speak to the manager. (Who never called me back). I got my truck back filthy, other services ignored. 3rd Silverado and last.

I am writing to formally document a series of catastrophic mechanical failures involving my vehicle, as well as serious inaccuracies currently reflected on the Carfax report. At approximately 15,000 miles, my vehicle experienced a catastrophic engine failure that required a full engine replacement. Less than 900 miles after the engine replacement, the vehicle then suffered a catastrophic transmission failure, which also required replacement. In connection with the transmission failure, there was also a fuel module issue that left me stranded. These failures were not minor or routine service events. One breakdown occurred on a major roadway and required the road to be shut down due to the vehicle being disabled. Another breakdown occurred on the Florida Turnpike as a result of complete engine failure, leaving me stranded in a highly dangerous situation. Despite the severity of these events, the Carfax report does not accurately reflect what occurred. The Carfax report does not state that the engine was replaced, and the transmission failure is not identified as a transmission replacement at all. Instead, it is reported as routine or normal service, without any indication that a catastrophic transmission failure or replacement occurred. This misrepresentation significantly understates the true condition and mechanical history of the vehicle. Due to the repeated catastrophic failures, the circumstances under which they occurred, and the risk posed to my safety and the safety of my family, I am genuinely afraid to drive this vehicle. I want to ensure that all of this information is properly documented and that the vehicle’s records accurately reflect its true history and condition.

CONCERN OVER 6.2 ENGINE FAILING WHILE IN CONGESTED TRAFIC

NHTSA ODI 11716572

My husband was driving on Plank rd/rt 219 towards Ebensburg PA when the truck started to buck and he turned off the main road and it shut down. It would not start just said low battery. I had it towed to the garage we use. They just confirmed it is the engine it locked up. I had the inspection for the recall and had the oil changed prior to this happening.

I was notified that my 2023 Silverado had an open recall (L87 Engine loss of propulsion). I brought the truck to the dealer for the recall on 8/19 with 35,921 miles on the vehicle. The inspection was performed and I was told it passed. When I asked about the extended special coverage they told me they didn't know what I was talking about. Only 4 months and 4,567 miles later, on 12/29, the vehicle shutdown in traffic and was not able to restart. The engine had failed and the starter fuse blew due to the motor being seized. The dealer relaced the engine due to the same recall that the engine had already been inspected and passed the inspection for.

My truck took my truck to Austin and back. Woke up the next day. Started it at approximately 4 o'clock in the afternoon and had engine oil low alert. Got out check the oil in my truck and there was none on the dipstick with the truck off of course. Checked at two other times allowing the dipstick to stay in for three or four minutes. Still no oil on the dipstick. Did not drive truck any further. Truck has the 6.2 L and I had the recall applied to the truck on December 8. The truck has 88% of the oil life remaining according to the truck.

I am sending this email to report that my 2023 Chevrolet Silverado had its rear brakes lock up momentarily on consecutive days (1/13/26 & 1/14/26) driving 70-72 mph.  Each occurrence came on without warning and only lasted a brief moment, but locked up hard enough for my rear wheels to screech and slam me forward in the truck, thankfully there were no other vehicles near me. I took the truck to the dealership first thing in the morning on 1/15/26 to be informed later that day that the truck didn't show any codes.  The service department at my dealership contacted the TAC Dept. at GM and they determined that the problem was caused by the brake light wiring from my truck topper (that was after they asked if the customer had added any accessories to the truck).  I have had the topper for 3 years without any issues.  I reached out to the company that installed the topper and the owner said that GM is giving me the run around and trying to point the blame elsewhere. He himself has installed 100's of toppers and they follow the wiring instructions from Leer Toppers. He did a 30 second Google search and said [XXX] , the problem you have experienced is well documented online, GM knows what the problem is with your truck". My truck was at the dealership for 5 days before they released it to me, even after I told them that there are known and documented cases of their trucks experiencing momentary rear wheel lockups. I have called GM Customer Service twice and left messages regarding my truck and TAC # and haven't received a return call. I am fearful that when this happens again and if it does so in the wrong place at the wrong time the end of this story may be tragic.   If I was pulling a trailer, driving on ice or in rush hour traffic I can't imagine the outcome. GM knows they have a serious problem and they is comfortable in releasing a dangerous truck back onto the roads.

On 1/24/26 I used the remote starter to warm up the truck and it started but within 3 minutes it shut off. The temperature was in the single digits. So I tried the remote again and it wouldn’t start. And the remote start hasn’t worked since and the check engine light is on. Two years ago when the brake module failed right before that recall the temperature was very cold that day too. Just two months ago the check engine light came on and that time the dealership said the battery failed . It also printed out a whole page of errors , at the dealership.

My truck passed the recall PICO test right at 20,000 miles. The dealer put thicker 0w40 oil in. Less than 2,000 miles later, upon hard acceleration from 5-8mph, the engine climbed to 58mph then lost power, shifted itself into Neutral and coasted to the side of road. Truck was towed and told the engine seized up. Changing the oil did not make sense to me as lubrication was always available previously, thickening it does not change the port mill sizes for properly oiling the crank bearings. Now the new engine is revised but I see failures in low milage 2026 models happening.

The contact owns a 2023 Chevrolet Silverado 1500. While driving approximately 45 MPH, the message “Reduce Acceleration – Drive with Care” was displayed. The vehicle was driven to the residence with an abnormal rattling sound coming from the vehicle. The vehicle was taken to a local dealer, but the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, and the failure was associated with a coolant sensor failure; however, it was unknown whether the dealer had repaired the vehicle. The dealer then informed the contact that the vehicle was safe to drive. However, while driving 65-70 MPH, the engine overheated and the vehicle stalled. Several unknown warning lights were illuminated. The contact was able to pull over to the side of the road, and the vehicle was towed to the dealer. The failure was initially related to a coolant sensor, and the dealer advised the contact that the part was ordered; however, upon following up, another technician advised the contact that a digital multivalve was ordered. The contact stated that upon returning to the dealer, the dealer advised the contact to sign the service documents. The contact stated that after insisting on reading the service documents prior to the signature, the dealer provided the documents to the contact; however, the dealer later snatched the documents from the contact while the contact was reading the documents. The contact stated that it was unknown whether the vehicle was serviced. The service manager later informed the contact that the vehicle could not be repaired because the contact and the dealer could not come to an agreement. The contact informed the dealer that the vehicle should be repaired under the warranty. The vehicle was picked up from the dealer unrepaired. The check engine warning light was illuminated. The manufacturer was notified of the dealer's denial by the dealer to repair the vehicle. The manufacturer informed the contact that there would be a follow-up with the dealer. The failure mileage was approximately 34,000.

On 1/21/26 traveling on a 4 lane divided highway, vehicle stalled, several warning lights came on and vehicle came to a complete stop in driving lane. Vehicle locked in park and could not put vehicle in neutral to push it out of highway. Several vehicle swerved to avoid and until tow truck came blocked a lane. It was about 3:30pm fortunately. So vehicle was visible and no accidents to our knowledge occurred. Thai created a dangerous traffic situation. It was caused by a fuel pump control module Whig was repaired 2 days later at local Chevy dealer. We were advised there were no recalls on this part but it is a common problem. GM should somehow find a solution and repair said problem

September 2025; the fuel control module failed at 75 mph in the left lane of I-45 requiring me to pull over on the shoulder in heavy traffic. I eas towed to my dealership 170 miles. At that time the recall test was performed on my 6.2 L L87 engine and passed inspection. The oil was upgraded at that time. Jan. 3, 2026 at 65 mph the engine died, once again on the highway at over 65 mph. Again I struggled to get to the right shoulder in heavy traffic. At the moment of failure, the engine revved from 1500 rpm to 3900 rpm and instantly fell to zero rpm and died. A message on the dash read unable to put in vehicle neutral. Again, I had it towed to my dealership where it's been diagnosed with a seized engine and I'm waiting (three weeks so far) on an engine replacement. I'm told the manufacturer rep has been to the dealership to confirm the failure and approved a complete engine replacement. There was never any advanced warning appearing on the dash. I have thorough maintenance records on this vehicle.

The motor blew with no notice, around 1000 miles after the recall inspection. My safety, along with the others around me was put at risk as I was in the fast lane during rush hour traffic with no motor to aid switching lanes to get to the shoulder. Finally died at one of the busiest intersections in the state, for the last time, as I was attempting to limp to the dealer via multiple restarts. leaving me stranded on the side of the road on a wonderful January day. The vehicle has been inspected by the dealer and slated for an engine replacement. No notice, I let off the gas, and when I went to accelerate again, the motor shut off.

Dear Sir or Madam, I am writing to formally report a safety-related defect involving the power unlatching tailgate switch on my Chevrolet 1500 truck and to request that this make and model be added to the current safety recall affecting Chevy HD vehicles. The power tailgate unlatching switch malfunctioned and would repeatedly attempt to open and close the tailgate while the truck was parked. On one occasion, this occurred continuously overnight. The following morning, my key fob was completely unresponsive, and the truck had zero battery life. The battery would not accept a charge, and the vehicle had to be towed to the dealership. Upon inspection, the dealership confirmed that the battery had been fully depleted and permanently damaged due to a short in the power tailgate switch. The faulty switch continuously drew power as it attempted to actuate the tailgate, ultimately destroying the battery. This failure created a serious safety and reliability concern, leaving me stranded with a completely inoperable vehicle. Given that this issue resulted from an electrical short and caused total battery failure, I believe it represents a significant safety defect. Based on the similarity to issues addressed in the current Chevy HD safety recall, I strongly believe this make and model should be included in that recall. I respectfully request that this matter be reviewed and addressed to prevent other owners from experiencing the same hazardous situation. Thank you for your time and attention to this matter. I look forward to your response. Sincerely, Charles Senn
