general problems of the 2023 Chevrolet Silverado 1500 - part 2

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.

Can shaft and lifters failed.

See attached document for complaint.

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.

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.

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 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.

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.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 mph, the vehicle lost motive power. The contact stated that several unknown warning lights were illuminated. The contact pulled over and turned off the vehicle. The contact restarted the vehicle after twenty minutes and was able to drive normally. The contact stated that after starting the vehicle and shifting to drive(d) or reverse(r), the vehicle failed to move. The contact stated that recently the vehicle stalled, and the check engine warning light was illuminated and was not turning off. The contact had taken the vehicle to a local dealer, but the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 19,000.

While driving at highway speeds, in traffic, all dash lights lit up and the engine shut off. The truck began decelerating on its own, I couldn’t brake and could barely steer. Luckily I was going fast enough that I managed to coast about a hundred feet to get partly out of traffic. The truck would never start again and I had to wait for 7 hours for gm roadside assistance to tow me to a chevy dealer that was 4. 6 miles away. 23 hours later the dealer called me and told me the starter caused the problem, in which I told them made no sense. 30 mins later they called and said the motor failed due to recall n252494003 for the l87 engine. My truck had passed the recall inspection for this recall on Sep 24th, 2025 and received the new oil that was supposed to prevent this failure. I had also just had the oil changed again around Nov 13th because the fcw module needed a firmware update and was not functioning. The truck had given no warning or issues previous to Dec 3rd.

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.

I was driving my vehicle when the check engine light came on and a message then came across the screen and stated the truck would no longer shift if I didn’t stop driving it. I took it immediately to autonation Chevrolet service on Nov 9. I received it back on 11/26 my service advisor said it passed inspection that no work was completed I needed to use high synthetic oil and filters for my truck to keep it going. This doesn’t sound correct when I’ve owned several chevy/GMC trucks. I only have 33k miles on my truck and want the recall fixed. Please help me get this taken care of.

After have the engine tested it was determined that my vehicle will receive the 0w/40 oil. After that change I have notices a lot of rattling and the engine not behaving like it should.

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.

While driving and idling, my 2023 Chevrolet Silverado 1500 high country equipped with the 6. 2l v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes p0304 (cylinder 4 misfire detected) and p050d (cold start rough idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted gm's technical assistance center (tac case #80413912). The service order report states: "due to unknown noise cannot perform recall. Called tac 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall. " the technician indicated this could be related to a camshaft and lifter issue, which matches the symptoms outlined in gm's active propulsion system recall for 6. 2l engines. Suggests gm aware & has not yet confirmed full recall coverage/repairs. This issue presents a significant safety risk because the engine could experience sudden power loss or failure while driving, potentially leading to loss of propulsion or control. These symptoms are identical to those described by gm in their recall documentation concerning valve lifter and camshaft failures. The issue has been reproduced and confirmed by the dealership, and all documentation, diagnostics reports, and service notes are available for inspection upon request. Warning/check-engine lights first appeared in October 2025, and the problem persists. Based on gm's recall acknowledgment of similar failures, I believe this defect should be fully covered under the existing recall, and I am requesting NHTSA's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.

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.

Driving down the road and the engine turns off with no warning lights, noise, or any indication of an issue. I was luckily able to use momentum and move to the side of the road. The chevy dealer has inspected the engine and concluded that the engine is blown.

I am filing a complaint regarding a potential recurring safety defect related to recall NHTSA 25v274 (gm n252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for recall 25v274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0w-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that gm approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0w-20 oil, contradicting the prior remedy intended to prevent this failure. This suggests the original recall fix was only a temporary measure, and the defect remains unresolved. I request that NHTSA investigate whether the current recall remedy adequately corrects this safety issue and whether gm’s use of 0w-20 oil could allow repeat failures. Additionally, I request assistance or reimbursement for vehicle payments, as my vehicle has been undrivable for an extended period due to a manufacturer defect. Thank you for your time and attention. I can provide all service records and diagnostic reports upon request.

We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

The vehicle shots forward after some delayed acceleration.

The contact owns a 2023 Chevrolet Silverado 1500. The vehicle was recently repaired under NHTSA campaign number: 25v274000 (engine and engine cooling). The contact understood that the option was to use a higher viscosity oil, replace the oil fill cap, and oil filter replacement. The contact stated that the remedy was insufficient to resolve a possible failure with the engine. The contact was hearing abnormal ticking sounds coming from the engine after starting the vehicle in the morning since the recall repair. The contact stated that once the engine had warmed up, the ticking sound ceased. There was no warning light illuminated. The manufacturer was informed of the failure and referred the contact to the NHTSA hotline for assistance. The contact had not experienced a failure with the engine.

I have a 2023 chevy Silverado 1500 3. 0l duramax trail boss. Temperature gauge keeps flocculating, engine fan kicks on at 100% and shuts off the ac. Warning on dash engine temperature to high ac shutting off and engine over heat. Took it to the dealership for the truck is still under warranty. They diagnosed it as a faulty coolant control valve. Was told it was safe to drive by the technician but I question that. Dealership ordered the part four weeks ago and it still has not come in. When I inquired about the delay, I found out it is on back order and the availability of the part long wait time. Further research found that this is a systemic issue owners are having with this specific engine since 2020. Yet gm has not done a recall nor is there supply stockage of this part, seeing how this part commonly fails.

So I experienced a p1098 code in my 2023 chevy silverado with a 3. 0 liter duramax. When you get this code the truck will go into “limp” mode with reduce (nonexistent) acceleration and only go to about 60 miles per hour (63) I think. This could become a large safety issue if someone was to experience this going down the highway. It is also a very common problem doing internet searches. Seems that gm knows this is an issue but does nothing about it. In fact they even tried to remove the part from warranty because it was happening so often. Seems like this is something the government should look into and see what the true cause of the issue is. On the other hand some of the reliability of these engines is caused by the government implementing many restrictions on the manufacture to meet certain requirements. I am frustrated this happened along with probably with thousands of other owners. Thanks!.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at a slow speed on the residential driveway, the contact noticed a large amount of water on the ground underneath the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with a water pump failure. The contact was informed that the water pump needed to be replaced. The vehicle was not repaired. The contact was informed that parts were on backorder. The contact stated that the vehicle remained at the dealer for more than forty-five days for parts availability. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 18,000.

Accelerating getting onto the highway, at about 65 mph I heard and felt 2 clunks and I lost propulsion. I made it to the side of the road and the vehicle went completely dead. I tried restarting it and it wouldn’t do a thing.

I own a 2023 Chevrolet Silverado 1500 zr2 equipped with the 6. 2l v8 l87 engine. My vehicle is included in recall number 25v274 / n252494000, which addresses manufacturing defects in the connecting rods and/or crankshaft that can cause engine failure. My recall status currently shows: "recall incomplete, remedy not yet available. " however, gm and NHTSA have already stated the remedy: a VIN-specific engine inspection, followed by either a replacement or an oil system update and extended warranty. I contacted my dealership, lochmandy Chevrolet in elkhart, indiana [xxx] ), and was told on June 1, 2025, that they could not inspect my truck due to lack of tools or VIN clearance from gm. I was given no estimated timeline for when I can get my vehicle serviced. My concern is that I’m driving a known defective vehicle with a potential for sudden power loss or engine seizure—a serious safety hazard. My truck currently has 19,500 miles, and I’m worried about continued use without an inspection or remedy. I’m requesting that NHTSA follow up on gm’s delays in remedy deployment, ensure dealerships are equipped for inspections, and provide vehicle owners like me with a firm timeline for repairs. Please open a case and provide a reference number. I can be reached at [xxx] for updates. I am documenting all interactions with gm and my dealership for safety and legal purposes.

This is the third time since the purchase date of July 2023, that my diesel 1500 silverado has gone into "reduced engine power" while driving. The first date was August 2024, while traveling down the interstate. The check engine light came on. My maximum speed was reduced to 50mph, and the transmission shifting was very jerky. This was extremely dangerous with the flow of traffic traveling 70+ mph. I returned to the dealer where the vehicle sat on the lot for approximately 60 days awaiting the part (valve body) from gm. Components were repaired through warranty. Fast forward to February 2025, "reduced engine power" notification came on again with the code p0747, p700. Returned to dealer, and after a week of sitting on the lot, the technician could not duplicate the code. I requested that a new fuel filter be replaced for piece of mind. Today, 3 mos. Later, as I was backing out of my driveway, my truck did not shift/engage into reverse. I was able to roll into the road & put it in drive, however it went into "reduced engine power. " the vehicle will have to be towed, at my expense, I'm sure, to further diagnose the cause. The truck does not move when shifted into reverse, and pressure is applied to the pedal. It is extremely concerning knowing a national recall on identical gm components has been reported, and yet I have had identical issues without resolution. Despite the known problems and safety risks, especially with a child in the vehicle during each failure, I’ve been left without consistent or timely support. I am requesting immediate assistance in diagnosing and repairing this vehicle, as well as a formal explanation of why this recurring issue has not triggered a broader response or replacement. At this point, I’m also considering pursuing further action through gm corporate or a consumer protection agency if a permanent resolution is not reached.

The contact owns a 2023 Chevrolet Silverado 1500. The contact was notified of NHTSA campaign number: 25v274000 (engine and engine cooling); however, the part to do the recall repair was not yet available. While driving 55 mph, the vehicle stalled with an unknown message displayed. Due to the failure, the vehicle was towed to the dealer. Several days later that the dealer informed the contact that a new engine had been ordered and the new engine was replaced. The contact stated that after retrieving the vehicle, there was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. The dealer was notified of the failure and an appointment was scheduled to have the vehicle serviced. The contact stated that while in a store parking lot, the vehicle failed to start after several attempts. Due to the failure, the vehicle was towed to the dealer where the mechanic discovered that a fuse connector was loose, causing the failure to start. The contact was also informed that the dealer failed to replace several screws and bolts back in place once the engine was replaced. The vehicle occasionally surged forward or hesitated while depressing the accelerator pedal, causing the contact to lose control of the vehicle while driving at various speeds. The manufacturer was made aware of the issues and the contact was informed that a refurbished engine was placed inside the vehicle and not a new engine as the dealer had stated. The vehicle remained with dealer due to safety concerns. The vehicle was not repaired. The failure mileage was approximately 26,000.
