POWER TRAIN, VEHICLE SPEED CONTROL, ENGINE
Component/System: The Allison 10‑speed (10L1000) transmission valve body catastrophically failed on [XXX], while driving Sunday afternoon down Galveston Seawall Blvd. The truck abruptly dropped from 45 mph into limp mode in heavy traffic, forcing me to pull into the bike lane to avoid being rear‑ended. The vehicle remains at Classic Chevrolet (Galveston, TX) awaiting the OEM valve body—which is on national backorder—and the complete transmission assembly is likewise unavailable. The failed valve body and transmission are available for inspection upon request. Safety Risk: Unexpected limp mode and gear lock‑up in heavy traffic create an immediate risk of rear‑end collisions or side impacts as surrounding drivers have no warning of sudden deceleration or loss of drive. Reproduction/Confirmation: Classic Chevrolet diagnosed and confirmed the failed valve body on May 12, 2025. Their service advisor and my assigned GM Case Agent (#[XXX]) have both acknowledged the defect but report no parts available for repair. Inspections: The vehicle has been inspected by Classic Chevrolet under warranty. GM Customer Care has reviewed my service orders and correspondence. No police or insurance inspections occurred, as no collision ensued—however, the roadside inspection at Classic Chevrolet confirmed the mechanical failure. Warnings/Symptoms: There were no prior warning lamps, messages, or symptoms before the failure. The valve body failure occurred without any advance indication.

ENGINE
The vehicle began making a loud fan noise in the engine after the summer began (06/2025) and the temperature gauge was elevated but not by a concerning amount. After an oil change (06/21/25) we were told that it was normal because of the weather. A week after the check engine light was coming on intermediately (began 06/28/2025) depending on the day and the temperature outside (we are currently in the middle of a heat wave). The vehicle was taken to the dealership (07/02/2025) where they determined that the coolant flow was too low and found that the engine coolant pump is faulty and needs to be replaced. f the coolant is low in a Chevy Silverado and the engine overheats, it can lead to significant and potentially expensive engine such as a blown head gasket, cracked engine block, or even a complete engine failure or fire.

FUEL/PROPULSION SYSTEM
I was driving on the freeway and smelled gasoline in the cab. I thought nothing of it as I was near a wreck and thought it was from that. About 10 miles down the road I was stopped in traffic and noticed my miles until empty was slowly declining as I was stopped. When I moved forward there was a puddle under my truck. I pulled to the side of the road and fuel was draining from the back of my engine all over the exhaust. I immediately shut the truck off. I cannot believe the gas didn't ignite as those catalytic converters get well over 536°. The truck was towed to the closest Chevrolet dealer over 10 days ago and I have YET to hear anything from them. I bought the truck used from another Chevrolet dealer 3 weeks prior, and it has had the L87 recall.

ENGINE
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!

ENGINE
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.

SERVICE BRAKES, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
While driving down the road I let off the accelerator to start applying brakes for a red light I was approaching, then the vehicle shut completely off and down shifted hard. After that it restarted a second later but had no power steering and no brakes. At this point I was approaching the red light with no brakes and power of my vehicle, the other traffic had a green light now and was crossing my lane of travel but I was luckily able to make it through the light in between vehicles without causing any harm to myself or others. After making it through the light I was rolling 10mph still helpless but seen a gas station on my right and rolled into their parking lot and drove towards a curb and used the curb to stop my vehicle. The vehicle had the following warning lights and messages: Lane Change Alert System Off, Brake system failure 62mph top speed, service traction control, service ESC, and trailer brakes disabled service required. I then got the vehicle towed to the dealership while still on and in the running position with all the codes still active. The dealer was able to scan the truck in and see the codes but told me they wouldn’t be able to get to it till the following week so they parked the vehicle and turned it off. When they got to my vehicle the following week they sent me a text and said I quote “Hey ****** its **** from Chevy, I do not have the best news lol he can not get it to act up and there are no current codes he has driven and nothing has happened, as of now there is nothing further he can do”. After receiving that text I called them to just be told they can’t get it to do it again and there is nothing they can do. But I told them I refuse to pick up this vehicle because it had a critical safety issue. This vehicle suffered a catastrophic failure, brakes and steering were lost in an intersection. If not diagnosed properly, this poses a threat to life.

ELECTRICAL SYSTEM
On [XXX] the automatic tailgate on my 2023 Chevrolet Silverado began opening and closing without reason. This obviously poses a potential safety issue. After investigating, I found that there is a recall on 2020 to 2024 Silverados, recall # N232426400. I called Penske Chevrolet in Indianapolis to schedule a time for them to confirm the tailgate switch short and execute the recall service. I was informed by Penske that my specific VIN was not included in the recall. This is not acceptable. Reporting indicates there are a number of other Silverado owners in the same position. Please investigate, as the current state of the recall is most certainly not inclusive of all vehicles that are affected. There should be no hesitation by Chevrolet to broaden the recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
GM has been manufacturing Silverado Pickup trucks with faulty transmission valve bodies for several years. There has been ongoing issues for several years with the defective Valve Body part. I purchase a 2023 for my business. It is presently at a dealership waiting on the part. It is my understanding GM has so many of these issues they can't keep up with the parts. I am told it could be weeks or months to get this part. Online you can see countless others who have waiting 2-3 months for a replacement Valve Body. How can they keep making the trucks with these defective parts. I still have to pay my $1,300 monthly payment while I have no use of my vehicle and they do not pay the full cost of a rental.

I take my truck in for regular service at my local Chevy dealership. When I found out about the recall on my engine back in April I immediately took my truck in. Was advised that they would address the issue. They did a regular maintenance and told me that they just used higher viscosity oil. I will be taking my truck in for the 3rd maintenance tomorrow 6/13/25. My vehicle status still shows that the recall needs to be addressed. I feel that I should park my truck due to the information provided on the recall of losing propulsion at any given time without notice. I also want to note that there is a noise coming from my engine that shouldn’t be there.

I have been experiencing the "SHIFT TO PARK" issue that GM Vehicles have been experiencing. My 2320 Chevrolet Silverado 3500HD High Country is not on the Recall for this issue, and I have approached my local dealer about it. I have not been able to fully addressed that issue yet, because I am dealing with a failed Transmission Valve Body that is covered under my drivetrain warranty, but not the GM recall for the 10L100 Allison Transmissions (GM N242454441). I undoubly have faulty parts/components contributing to this issue the fails to completely allow my truck to shift to park and allow me to completely turn the truck off and leave the vehicle.
