ENGINE
I am reporting another engine failure on the 6.2L L87. This engine passed the initial recall testing and the oil was changed to 0W40 on September 30, 2025. However, my engine in my 2023 LT Trail Boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [XXX] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the GM dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a PO for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to GM only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by GM. They have clearly failed with this engine and are replacing the failed engines with the same thing! It is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [XXX] old children in the truck!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

POWER TRAIN
At cold start vehicle often required several seconds for the transmission to engage before moving. After traveling at highway speed (45+ MPH) vehicle began to make clunking noise as if the transmission were changing gears but it was not and the RPMs on the tachometer did not change. Instances became worse and more frequent over 6 month period, vehicle never displayed any codes and no notifications or check engine/transmission lights on driver information center. Took vehicle to O’Fallon Buick GMC and was advised torque converter and transmission valve body had failed and needed replaced. I inquired about ongoing issue with this vehicle based on my findings online and was told it was not a recall issue at this time. Truck has 74,000 miles and service records for all maintenance to date.

FUEL/PROPULSION SYSTEM, ENGINE
I'm reporting a 5mpg fuel economy reduction immediately following the 6.2L L87 engine recall (NHTSA #24V795000). I use 93 octane and monitor my fuel mileage consistently. I bragged about my fuel economy in my 6.2l until after the recall was applied. This is going to cause a financial hardship as I'm on fixed income after Servicing 29 years in the Army and 100% disabled. There is no other reason my mpg should have changed as my driving habits have not.

FUEL/PROPULSION SYSTEM
The high pressure fuel pump “grenaded” while driving on the interstate. Caused an immediate shutdown and barely got off the main lane to the shoulder in extremely heavy traffic putting me, my wife and others in imminent danger. The components were inspected by the dealer mechanic and insurance adjuster and they said that is what happened and that there was no reason for it to have happened. A warning of reduced power appeared about 3 seconds before the truck completely shutdown.

ENGINE
While driving on the freeway without warning, my engine stopped working. My vehicle was towed to the Chevy dealership where they confirmed that I was the latest victim of the ongoing engine failure problem with the 6.2 L engine. There was no warning, no sign that I had a problem. My engine just simply stopped working on a busy freeway. I was barely able to make it to the shoulder where I had merging traffic coming on the freeway behind me. I’m deeply concerned that Chevy will replace it with the same faulty engine and I will be put in the same danger situation again in the future.

FUEL SYSTEM, DIESEL, ELECTRICAL SYSTEM:INSTRUMENT PANEL:FUEL GAUGE
The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that on two separate occasions while hauling the camper, the "High Diesel Exhaust Fluid", Exhaust Fluid Range", and "Fill DEF (Diesel Exhaust Fluid) Now" warning messages were displayed on the instrument panel. The messages indicated that the Diesel Exhaust Fluid was low and needed to be replenished. The contact stated that the failure caused the instrument panel to freeze and not operate as needed. Upon attempting to refuel the vehicle, fuel failed to enter the fuel tank since the diesel tank was full. The vehicle was taken to a dealer, where the contact was informed that the failure was an electrical glitch and that there were no issues with the Diesel Exhaust Fluid system. The contact was also informed by the dealer of Technical Service Bulletin: 22-NA-150, which the contact related to the failure. The dealer reset the vehicle, which caused the instrument panel to return to normal operation. The manufacturer was then notified of the failure, and the contact was informed that vehicle was not included in the TSB. The contact was given a case number and was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 55,000.

POWER TRAIN, VEHICLE SPEED CONTROL, ENGINE
My engine completely died, and a complete loss of propulsion happened. My safety was put at risk due to no power while on busy highway. This problem with L87 engines (6.2) has been reported extensively. The vehicle was inspected for GM Program # N252494000, NHTSA 25V74 for above issues and was inspected on 2025-08-28. Inspection passed, but the failure ultimatel happened on 2025-02-25. Dealer indicated engine was covered under original powertrain warranty and GM would send a remanufactured engine. Dealer has still not received the engine as of Monday (2/23), which is almost a month later. While driving on a US highway in a rural area, my engine suddenly died while driving approximately 60mph. The restart engine light came on, and I quickly was unsure what was happening as I felt myself slowing down slightly after realizing I had no power and the engine would not restart. I believe it went to neutral automatically. I was in the inside lane, and it was incredibly dangerous due to traffic around me. I could not easily exit to side of road due to the traffic, but luckily a gap formed, and I was able to abruptly get off the road. I have kids in the car daily, and this would have been life threatening had it happen in any other scenario, or especially in a larger city or busier highway. I am confident this is related to GM's issues with the 6.2 liter engines. I have a 2023 Silverado 1500 ZR2 that this happened to. The loss of propulsion is clearly due to the defect in these engines.

The vehicle lost power and went into limp mode on 3/3. I had it transported to a dealership and they said there was metal containments in the motor. I got it back on 3/17 and they said all was well but it never drove right. It broke down again on 3/20 and the said the throttle body was out. Why had they not found this issue before? This seems to be a recurring issue with this model truck.

The Def guage does not work properly. After topping off with DEF the guage would not register being full. Also the guage would read over half full and within minutes I would receive a notification that the truck was going into limp mode due to be out of DEF. Happened several time while on a trip. Also truck went into limp mode while DEF was full.

POWER TRAIN
Valve body in the transmission failed while driving on the freeway, all of a sudden it was like the car was in neutral and the RPM's went to redline. Dealer is telling me it is a known issue and has no idea on when they will be able to get parts because they have been on backorder forever. Says that they also have to replaced the Transmission Control Module (TCM). same thing no eta on parts. If this is a known issue why have they not recalled them. Fom what I see on line this failure is happening a lot to people, hence the unavailability of replacements parts.

ENGINE, WHEELS, VEHICLE SPEED CONTROL
Driving at highway speeds the message center prompted us to restart the truck and put itself into neutral. Upon attempting to do so, the message center read conditions not correct to shift. We were traveling in a single lane highway thankfully on a decent where we coasted into a parking lot. The truck list all power steering and brakes. We turned the truck off and attempted to restart. Lights were randomly flickering on and off, but the starter couldn’t turn the engine over. After 3 hours of waiting on Chevrolet roadside assistance we obtained our own tow service. The truck tires had seized up causing the driver to drag the truck into the flatbed. The emergency brake kept resetting itself. The following day 7/13 Chevrolet had the truck towed to the dealership. On Monday 7/16 we were informed the engine had catastrophic failure with less than 24k miles. This is the second major engine breakdown as the first was at 5k miles where one side of the engine had collapsed lifters. Engines are on back order but in reviewing other experiences the replacements experience the same issues. The truck is not a safe vehicle to drive.
