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.
2023 Chevrolet Silverado 1500 engine complaints
Page 4 of 7: complaints 71 to 100 of 180, newest first, as owners wrote them.
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.
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
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.
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.
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.
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.
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.
Can shaft and lifters failed
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.

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.
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.

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 the federal safety agency's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.
1.Coolant control valve failure 3 times within 125,00 miles causing the engine to run hot without overheating indication, losing heater and defrosting capabilities unable to operate safely with windshield freezing, 2. in addition this also caused the engine to run hot enough to burn manifold gasket and cracking manifold creating carbon monoxide to enter through cab vents. $4500 repair cost-that in order to operate safely. 3. Finally on star safety features not available due to module battery dead only after 2 years gps,emergency call and everything else included in this safety feature unavailable $1,000 cost manufacturer or dealer will not recognize any of these due to warranties and expiration.
I was driving on the highway doing 75 and the truck started jurking and slowing down by itself and getting loud. The display stated reduce speed and the check engine light came on..
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 the federal safety agency 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 the federal safety agency 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.
The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.
See attached document for complaint.
The contact owns a 2023 Chevrolet Silverado 1500. The vehicle was recently repaired under the federal safety agency 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 federal safety agency Hotline for assistance. The contact had not experienced a failure with the engine.
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.
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.
