I am writing to express my serious concern and frustration regarding the unresolved recall on my 2020 Chevrolet Silverado 2500 (VIN: [xxx] ). Despite multiple visits to multiple dealerships, I was repeatedly told that the necessary parts to complete the recall repair were on back order and instructed to “wait for parts. ” no interim solution or assistance was ever offered. As a result of this delay, my vehicle broke down without warning, leaving me stranded on the side of the road. This created a hazardous situation and significant disruption to my day. To make matters worse, I had to pay out of pocket to have the truck towed to a repair shop in an effort to get it operational—an expense I should never have incurred given the known recall and repeated attempts to have the issue corrected by Chevrolet. I have been a loyal Chevrolet owner and have always trusted the brand for its quality and dependability. However, this delay and lack of proactive support is causing significant inconvenience and eroding that trust. This situation is unacceptable for several reasons: 1. Safety risk and recall obligation: Chevrolet acknowledged the defect by issuing a recall, yet I have been forced to operate a vehicle that does not meet your own safety standards for months. 2. Repeated service attempts with no resolution: I followed the proper process and visited an authorized dealer multiple times, only to be turned away each time with no solution beyond “wait for parts. ” 3. Breakdown and financial loss: the vehicle failure and subsequent towing expense are a direct consequence of Chevrolet’s inability to provide timely parts or alternative accommodations.

Transmission valve body issue.

In December of 2024 safety recall n2424440-01 was applied. On the morning of Saturday August 23, 2025 while driving on a two (2) lane highway with the cruise control set to 60 mph the vehicle “shuttered” then the shifted into a lower gear locking the rear wheels bringing the vehicle to an almost complete stop in very short distance. I was able to pull off the road out of traffic. Since it was a light traffic morning, no one else was close limiting the risk to me. Had there been anyone behind me they would have been caught off guard by the sudden stop with no signal of brake lights showing. The vehicle is in “limp mode” and will not exceed 35 or 40 mph. The vehicle will shift in to park and neutral. It will not move in reverse forward. The vehicle has been transported to the nearest Chevrolet dealership for diagnostics and service.

Tramsmission valve body failed causing lack of porpulsion and inability to put the pickup in park while in traffic. After coasting to the nearest chevy dealer they cleared the codes so I could drive home and take it to my local chevy dealer ASAP. The local chevy dealer refused to inspect it until the check engine light came back. One week later the transmission violentley down shifted into 5th gear and stayed there until it was shut off it would not go into park. On the second occurances it gave codes p0700 and p0747. It was towed to the local chevy dealer who claimed to inspect on 3 ocassions but efused to give me any paper work on the results of the inspection. Beacuse they never inspected it. I took it to an indepent mechanic to replace the valve body. The 5000 miles since the valve body replacement have been uneventful. No indicators of failure were seen before the inital failure.

While towing my travel trailer at 55 mph the truck rear tires locked up causing an alerting situation. The transmission automatically shifted out of tow/haul mode, the cel illuminated and the following message appeared on the dash "reduced acceleration condition, drive with caution". This event happened a total of 3 times within a 20 mile distance. Because it was a short burst and I was traveling on a straight section of roadway, the risk of accident was moderate. This would have been a high risk of danger if I were on a curving downhill section of roadway. The situation was confirmed by my local dealer through a diagnostic check exhibiting a p0747 and p0700 error code. There were no cels or other warnings prior to the lockup. The diagnosis was a problem with the transmission valve body. A new valve body was ordered and arrived 14 days later. After the new vb was installed the symptoms appear to be gone after driving about 50 miles.

Truck went into “reduced acceleration” or “limp mode” while pulling my camper. Took truck to kool Chevrolet in grand rapids, mi. They confirmed it is a bad valve body on the transmission. No estimated time from chevy on getting a replacement valve body. They confirmed this is a widespread known issue and could be weeks if not months. I have a family camping trip planned for the upper peninsula of michigan in mid July and they aren’t giving not giving me any indication that I could have my truck back by then.

Gm has acknowledged the problem and has issued a recall on transmissions effecting 2020 – 2022 Chevrolet Silverado 2500/3500 heavy duty trucks equipped with diesel engines manufactured between January 28, 2019 – January 11, 2022. Our truck, a 2021 Chevrolet Silverado 2500hd, was taken in to d’arcy Chevrolet in morris, IL to have recall n242454440 – momentary rear wheel lock-up – transmission and engine control module programming with sp. Under this recall dealers will install new transmission control module software, free of charge. Gm will provide a special coverage program to cover the repair of transmissions that are identified by the remedy software as containing a defective control valve. After the recall service was performed we were told by the dealership that the transmission needed to be replaced. It clearly states under the recall performed that gm is to provide special coverage to cover repairs that are identified by the remedy software as containing a defective control valve. Also, by law, dealers are never to charge for recall repairs. But gm and the d’arcy Chevrolet are refusing to cover the repair costs for the transmission under special coverage program.

While driving my truck it shifts into tow mode by itself, also on June 1st 2025 my truck shifted to 4 low by itself .

Owner from brand new (16 miles) multiple complaints through ownership of harsh shifting, jerky throttle on and off, excessive engine braking, and have been stuck on the side of the road 3x due to the same situation. Never was a code thrown so I was continuously told there’s “nothing wrong. ” on [xxx] I was driving [xxx] out of denver making the climb towards [xxx] to home. As I had my cruise control set at 65, out of nowhere my truck locked up what seemed to be the rear wheels completely, causing my rear end to sway violently. I immediately slowed down and pulled over with no indications or lights being illuminated on my dash. I turned the truck off and let it sit for 10 minutes and restarted it. Having no issues I signaled back onto [xxx] and the truck accelerated to nearly 65 with no issues. As I hit 62 on the dash it again locked up the rear tires. I again pulled over, this time questioning what could be causing this, knowing the first time indeed was what happened. I put my truck into park, and still had no warning lights or check engine light. I then put my truck into neutral and then clicked the auto button thinking maybe something with the rear end is locking my brakes up. Upon doing so I again entered the roadway, big mistake on my part as this time upon reaching 60+mph all 4 tires simultaneously locked up. How I didn’t roll, I have no idea. Easily the scariest set of events I’ve ever faced while driving and that’s considering all of the insane drivers on our roadways today. I literally lodged a complaint with Chevrolet the same day I bought this truck before ever even leaving the dealers lot, and have had zero communication from them other than myself reaching out. They have ignored the problem literally from day one and it easily could’ve cost me or someone else their life. I’m appalled that to date they are still selling these trucks, replacing the valve bodies with the exact same faulty ones, and allowed to put others in danger constantly.

When vehicle is placed in park the safety lock will not allow the key to turn to the "off" position and be removed. The vehicle will not turn "off" any further than the accessory position. Sometimes after turning the steering wheel back and forth while working the ignition the key will release. If this does not work after a minute or so, sometimes you can start the truck and immediately turn it all the way off and get the key to release. If all of that fails the last option is to disconnect the battery. It is an intermittent issue that will happen 5 times a day for a week, and then will not replicate again for a week or two.

Component/system: the allison 10?speed (10l1000) transmission valve body catastrophically failed on may?11,?2025, 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 (#70179205) 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.

While driving to work one day I came to an intersection and stopped. When I went to accelerate to take off my truck shuttered and made a loud noise. The truck immediately went into "reduced power mode" with no warning. I could no longer drive the appropriate speed limit and had to constantly pull over to allow other vehicles to go by. This caused a traffic jam on narrow roads to get the vehicle to a safe spot. My truck only has 43,000 miles on it. The dealership confirmed that the truck has a bad valve body and needs to be replaced. The truck is currently sitting at the dealership and has been since may 15, 2025. As of today, July 18, 2025, gm still does not have an eta on when the part to fix my truck will ship out.

70,000 mile complete transmission failure despite being serviced on-time, as per the guidance. Failure happened while driving and it became dangerous to try to maintain highway speed. Quoted $8390 to replace by the local chevy dealership and quoted 4-6 weeks delivery for backordered parts. This is an unacceptable situation that gm and other manufacturers have artificially manufactured. They design everything to the bare minimum to save fractions of a cent per part, and then they intentionally make the parts unavailable and then the dealership pushes you to trade the broken vehicle in at a massive loss just so you can get back on the road in a newer, more expensive vehicle. This sort of behavior is causing immense financial harm to american families.

My truck has been having the "shift to park" warning for quite a while now. Truck has roughly 72000 miles. Before it would happen intermediately, now it happens all the time.
