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

2023 1500 RST 6.2. Recall was done and performed last year. Truck passed so they changed the oil and sent me on my way. I have had zero issues up until last week. My gut tells me the replacement is going to be the same engine with the same failing parts that I already have so expect I may have issues in the future even after the new engine. -on interstate going 55MPH, went to accelerate to 70MPH and throttle did nothing; no rpm,no down shift, no speed change. Just dead. Suddenly the truck shut off the engine and kicked my transmission into neutral. I tried to restart the truck hoping it would fire just long enough to get me to a safe zone with no luck as the starter would turn but nothing from the engine. Mind you this was rush hour in a construction zone with no shoulder available at the moment. Luckily I coasted, got to the slow lane and was able to veer off safely onto the side of an exit ramp. No notice, no way to safely limp my truck, just a complete shut down. How this isn’t a lawsuit or more people haven’t been seriously injured or worse is beyond me- a total shutdown while driving highway speeds and no way to overcome or at least limit the speed for a short period is unbelievable. Even though warranty is now through 2033/150k miles for the powertrain due to the recall, and I’ve also thought about adding 3-4 years extended for bumper to bumper with all the tech, I now have ZERO faith in my truck or my safety once I get it back. I’m sure the trade value will also be considerably low due to the 6.2. I’ve owned Chevys for 12 years and am either going back to the 5.3 or switching brands altogether. Possibly a 5.7 hemi without etorque.

RE: FORMAL COMPLAINT–RECALL FRAUD & VIN TAMPERING SUBJECT: Falsified Recall N252494000 & 18 U.S.C. § 511 Violations VEHICLE: 2023 Chevy Silverado (VIN: [XXX] ) INCIDENT: March 7, 2026 FROM: [XXX] | [XXX] I am reporting severe Federal Recall Fraud and VIN tampering by Kunes Auto Group (WI). GM records and physical evidence prove Kunes falsified Safety Recall N252494000 (L87 Loss of Propulsion) and sold an illegally rebuilt wreck with mismatched VINs. 1. Falsified Recall: On 4/9/2024, Kunes logged a PicoScope Inspection marking the recall "Passed" (Trans #XX-XXX). The NHTSA remedy requires installing a 0W-40 oil cap/flush. When the engine seized on 3/7/2026, it still had the factory 0W-20 cap. Kunes billed GM for a safety remedy never performed. 2. Concealed Defects: Despite the "Closed" recall, the truck exhibited L87 defect symptoms. I brought it to Kunes three times (Oct 2025 - Feb 2026). They dismissed the warnings and released the truck as safe. 3. VIN Fraud (18 U.S.C. § 511): The 2023 truck has 2025-stamped frame/axle parts. Holz Motors (authorized GM) blacklisted it on 3/6/2026 (RO #1583470), stating in writing: "DUE TO... MISMATCHED VINS DOOR TO DASH, SALVAGED REAR AXLE... HOLZ WILL NOT BRING THIS TRUCK IN." 4. Highway Failure: On 3/7/2026, the L87 motor suffered total Loss of Propulsion at 70 MPH in traffic. The sudden loss of power steering/braking nearly caused a multi-vehicle fatality. REQUESTED ACTION: 1. Audit Kunes’s PicoScope data for the 4/9/2024 transaction. 2. Investigate remedy fraud (missing 0W-40 cap). 3. Investigate tampered/mismatched VINs and off-the-books rebuild. 4. Sanction dealer for fraudulent safety certifications. I declare under penalty of perjury these statements are true.

On [XXX], my 2023 Chevrolet Silverado 1500 LT caught fire while parked in my residential driveway at [XXX] . The vehicle had been started approximately 10 minutes earlier using the factory-installed remote start system. The vehicle was unattended at the time. My neighbor noticed the vehicle on fire and called 911. The Andover Fire Department responded and extinguished the fire. The fire department indicated the fire appeared to be electrical in nature. The fire appeared to originate in the dashboard and steering column area based on visible damage and fire progression. The vehicle had approximately 60,000 miles and was properly maintained. There were no prior warning lights, messages, or symptoms before the fire. The remote start system was factory-installed and not aftermarket. The vehicle is currently available for inspection by insurance, manufacturer, or investigators at [XXX] . The vehicle is likely a total loss due to the extent of the fire damage. This incident posed a serious safety risk as the vehicle caught fire spontaneously while parked near my home. The fire could have spread to my residence or caused injury if someone had been inside or near the vehicle. The fire department responded, and an official fire report is pending. Insurance claim has been opened and inspection is pending. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

General Motors sent me a letter regarding a safety recall regarding my 6.2L V8 gas engine (ROP L87). Safety recall N252494000. I learned that my truck has the potential to have a complete engine failure. I took my truck to the dealership and all they did was an inspection and changed the oil on it. I'm not a mechanic, but total engine failure is concerning to say the least. I doubt simple change in oil thickness remedies serious recall. I learned there is an open lawsuit regarding this issue. I need Chevy to take this matter more serious, Im driving my family around in a ticking time bomb. I demand more than a band-aid. I want Chevy to replace my engine with a new reliable one.

While driving at 70mph, my vehicle spontaneously shifted into Neutral and therefore dropped power to the transmission. I was unable to shift out of Neutral and therefore had to coast to the shoulder. Upon coming to a complete stop, my truck independently shifted into Park. Again, I was unable to shift out of Park. I turned my truck off, let it sit for a few seconds before unsuccessfully attempting to restart my vehicle. Multiple attempts to restart my vehicle continued to be unsuccessful and the vehicle system would reboot then shut off.

My vehicle was part of the recall N25494000 L87 Engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, PicoScope Inspection was done and vehicle passed. Oil was changed to 0W 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no Engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle Engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.
