Power Train Problems of Chevrolet Silverado 1500 - part 1

The rear wheels suddenly locked up while driving. It did it twice then the check engine light came on and then the transmission would not shift into gear until I turned off the truck and turned it back on. This happened 3 days in a row all while driving. Exactly the same. No prior symptoms or warnings before the incidents happened. The vehicle is currently at the dealership being inspected. There is a recall (n242454440) that addresses this issue but I'm being told that my truck is not covered under that recall because my VIN is not part of it.

Summary of incident: on March 28, 2026, while traveling at 70 mph on the florida turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into neutral or park. The engine cranks but will not start. 1. Component failure & availability: the exact component is currently unknown, but the failure involves the powertrain, fuel system, and electronic transmission control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety risk: the sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem reproduction: the vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: the vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning symptoms: there were no warning lamps, "check engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

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.

Vehicle experienced a sudden rough shift followed up by hard shifting and transmission locking up rear wheels. If I was traveling at a higher rate of speed (over 30mph) a accident could've easily resulted. Check engine light and vehicle went into reduced acceleration mode after 3 to 4 severe shift occurances. Dealer has vehicle and found the valve body of transmission was faulty and will be replacing entire valve body. Still under factory warranty. Mileage at occurance was 45,006 miles.

Truck went in for the recall around Nov/Dec 2025. Passed recall for 6. 2l crankshaft and new oil was put in the vehicle. Today the truck lost power while driving and the check engine light came on to include a message saying the transmission went out. The vehicle is now un drivable and with a Chevrolets dealership waiting to be fixed.

The electronics freeze up and sometimes the stereo turns off and won't come back on. The transmission perks and then revs up then hits gear and kicks real hard. The transmission feels like it's going to vibrate out from under the truck going down the road at certain speeds!.

While attempting to accelerate, the vehicle stalled and failed to move. The contact stated that the transmission failed to operate properly, and the vehicle was unable to shift into gear. The contact stated that the vehicle shut off with the check engine warning light was illuminated. The vehicle was unable to be restarted or moved from the roadway. An independent mechanic diagnosed the vehicle at the residence and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 80,000.

1. Transmission shudder at highway speeds between 64 and 83 miles per hour. 2. Pour fuel economy; 12. 5 mpg @ 65 mph, 11. 8 mpg @ 70 mph, 8-9 mpg @80 mph towing a 2025 utility trailer wiith motorcycle approximately 1800 pounds.

The vehicle experienced a sudden loss of 4wd capability and transmission communication while driving. The dealership diagnosed a defective battery ground cable. Gm has issued customer satisfaction program n252515590 for this exact issue, but they are refusing to cover my specific VIN despite the truck exhibiting the exact failure described. This defect causes the vehicle to lose critical powertrain functions, posing a safety risk on the road.

I'm reaching out to hopefully prevent a horrific situation not only to myself or any other gm owners. My vehicle has been diagnosed with having a faulty transmission valve body. There are so many that have failed that the dealer cannot give me a time when the part will be available. Because my vehicle is out of warranty, they are not willing to help. When I looked online it said as of late 2024 there were at least 1,888 field reports were identified.

My l87 6. 2l engine shut off on the interstate while driving in traffic at 70mph. I coasted to the left shoulder and attempted to restart it, but it would not turn over. I had it towed to a dealer where they diagnosed it as seized. Currently waiting for a new engine to arrive with no eta. I had no warning signs or sounds. Two months prior it had the recall completed passing the pico test and changed to the heavier oil.

My coolant control valve has failed, the dealership is saying the radiator is now leaking at a weld. They said this is a know issue, but are refusing to repair it. It is caused by the know failing ccv, causing the radiator to overheat.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the transmission was slipping. There was no warning light illuminated. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000.

On 03/13/26, I was taking a family trip when all of a sudden my 2021 chevy silverado (with 6. 2l v8) began to lose power and shake uncontrollably causing me to make an emergency roadside stop. Fortunately, traffic was light and I was able to avoid a collision. I immediately heard a loud knocking sound coming from my engine and several check engine safety lights were displayed. On 3/16, I brought my truck to a local gm dealership and was advised that I needed a complete new engine replacement due to catastrophic engine failure because my rods and crankshaft had blown in my engine. The dealership checked for recalls on my truck but were surprised that my VIN did not pull up a recall even though there was a recent major engine recall (# n252494000) issued for my exact model truck with the same issues my truck displayed. It should be noted that my vehicle had less than 24,000 miles on it and I have kept up with regular oil change and maintenance service and that before this issue I have had zero issues with this vehicle. To make matters worse my powertrain warranty expired 2 months prior to this incident so I am having to pay out of pocket over $12k for a new engine. On 03/19/26, I contacted chevy but was told there was nothing they could do for me and stated that NHTSA would have to get my vehicle added to the recall. I am requesting that my vehicle and others like it get added to this massive engine recall so I can get reimbursed for my new engine and also to protect other families from possibly being involved in a major unavoidable crash. Thanks in advance for your help!.

I replaced the fluid in my truck at 142k miles and when I went through all of the gears and checked for drips or leaking it was fine on that front and then I went to reverse and all of the gears were neural and only revved and when I went into neutral it started driving forward like it was the drive gear.

2023 1500 rst 6. 2. Recall was done and performed last year. Truck passed so they changed the oil and sent me on my way. I have had zero issues up until last week. My gut tells me the replacement is going to be the same engine with the same failing parts that I already have so expect I may have issues in the future even after the new engine. -on interstate going 55mph, went to accelerate to 70mph and throttle did nothing; no rpm,no down shift, no speed change. Just dead. Suddenly the truck shut off the engine and kicked my transmission into neutral. I tried to restart the truck hoping it would fire just long enough to get me to a safe zone with no luck as the starter would turn but nothing from the engine. Mind you this was rush hour in a construction zone with no shoulder available at the moment. Luckily I coasted, got to the slow lane and was able to veer off safely onto the side of an exit ramp. No notice, no way to safely limp my truck, just a complete shut down. How this isn’t a lawsuit or more people haven’t been seriously injured or worse is beyond me- a total shutdown while driving highway speeds and no way to overcome or at least limit the speed for a short period is unbelievable. Even though warranty is now through 2033/150k miles for the powertrain due to the recall, and I’ve also thought about adding 3-4 years extended for bumper to bumper with all the tech, I now have zero faith in my truck or my safety once I get it back. I’m sure the trade value will also be considerably low due to the 6. 2. I’ve owned chevys for 12 years and am either going back to the 5. 3 or switching brands altogether. Possibly a 5. 7 hemi without etorque.

(lifter/cam shaft) - has the problem been reproduced or confirmed by a dealer or independent service center? yes confirmed by dealer hiley chevorlet, case # 90727922 w/ general motors. - has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes by service dealer hiley chevorlet, case # 90727922 w/ general motors. - were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, no check engine light or messages. Bought the 21' silverado about 18 months ago, recently the truck began to sound and drive terrible, it was found to be a bad high pressure fuel pump, bad lifter, and damaged camshaft. Dealership acknowledged that these are common issues w/ this model & year of vehicle and the parts are defective parts that they use in the manufacturing process of this model. They deemed it was out of warranty range as it's still under year 5 however I exceeded the powertrain warranty by 10,000 miles so they will not cover the issues and damage.

On road trip from mi to NY. No lights or warnings but transmission failed. We were able to get safely off highway into parking lot. Tried to have towed to chevy dealer but could not look at for days. Able to take to aamco & need to install new transmission in ohio!.

We purchased a 2018 fully loaded chevy silverado ltz/z71 ($60,000) in 2019, with the idea it would last. After being super meticulous with maintenance and keeping this vehicle in top condition, we just passed the 110,000 mile mark. I have receipts of all the work/maintenance completed on this vehicle. I began to hear a ticking noise in the engine block, and the check engine light came on, so I pulled the codes and went to a local transmission/engine mechanic to find that I have a bent push rod (manufacture failure) due a failed lifter/afm system. I opted not to take it directly to the dealer as they charge $179 base rate for diagnosis which could increase depending on the diagnosis needed. After numerous calls, I found this is a very common ($7,500-$11,000+) issue with '18-'21 models. Explored my options only to find the 2021- 2026 engines are worse with issues involving crankshaft, engine seizures and an active lawsuit with the new 6. 2l v8 engines. (silverado, GMC sierra, tahoe, suburban, yukons) I was then pointed in the direction of speaking to the gm manufacture directly, again. I had contacted them numerous times and was told the damages, even though are not preventable and are directly due to a manufacture error. I was told I must take my vehicle to a licensed service dealer to be diagnosed. I informed them, that I was already told my vehicle would not be covered so I did not feel the need to endure additional cost only to be told the cost would again, not be covered. I'm not seeking full payment; I even mentioned goodwill assistance of which they denied; however, I'm without a vehicle and have received very little to no communication in resolving this issue, which is an issue I'm finding is happening to many others alike and general motors corp, is not taking any responsibility or accountability in this matter.

Transmission skips 1st gear and jumps and shakes vibrates. The transmission has to have a total rebuild.

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.

When entering traffic vehicle wheels locked up and engine stopped, when restarted vehicle was in limp or reduced power mode, check engine light is on, message on screen and in app identifies transmission and electrical problem. Anti slip was engaged automatically upon restart.

This truck has a 6. 2 engine that was recalled, inspected, and made the switch to the new oil, but then failed. I believe you already have a recall query rq26001 related to this matter. I received the recall notice July 2025, took the vehicle to covert bee cave in austin, TX July 2025. They told me it passed inspection and put the new oil cap on. Within two weeks I began having transmission issues. I left the truck with them for three weeks and they could not do anything about the transmission. The transmission issue did not reappear until a couple of weeks ago. I took it to capitol Chevrolet and they replaced a shifter rod in the transmission, but I am not convinced that was the issue as it still shifted rough. Just a couple of days later, before I could take it back to have capitol look at the transmission, and while driving on an interstate south of san antonio, TX, the engine slowed down, flashed a warning "oil pressure low turn vehicle off" and it continued to slow. I was barely able to exit the interstate, the truck stopped and would not restart. I had it towed to vara Chevrolet in san antonio ($440 tow expense) and it still would not start. The technician finally inspected it a few days later, said the engine is seized, and they will need to replace the entire engine, and that it is covered under warranty (there was plenty of oil in my engine). He did not say anything about the transmission. I believe this is an example of my vehicle passing the recall inspection, changing to the new oil, and the engine still failing - and at a very dangerous time on the interstate.

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving approximately 40 mph on four occasions, the rear wheels locked up. The contact slowed down and steered to the side of the road, and inspected the vehicle, but found no fault with it. The vehicle was taken to a dealer but was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 101,411.

The transmission valve body failed. Even after the recall software update that it received. There were no warnings or codes, the transmission simply just started shifting hard and would not go in reverse. This type of incident could prove to be very dangerous especially in high traffic areas. There are only 35,000 miles on the Silverado 1500 trail boss. I took it in to the local Chevrolet dealership, and they confirmed that it was the valve body.

Valve body went out while driving, drastically reduced speed, threw code p0747.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that while the vehicle was parked and running, the transmission remained in neutral(n). There were no warning lights illuminated. The contact stated that while attempting to move the gear shifter, the transmission remained in neutral(n). The vehicle was able to restart; however, the failure recurred. The contact was able to drive the vehicle after several attempts. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the transmission had failed and needed to be repaired. The vehicle was repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,200.

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.

While turning left, the transmission stuttered and got stuck in first gear. I did some basic research and learned that this is a known issue with 2020-2022 Chevrolet silverado vehicles. I attempted the suggested fix which worked briefly. I then took the vehicle to my local Chevrolet dealer for repairs. After further research I learned that this is a known issue with my year and model of silverado. Gm further voluntarily offered a 15 year, 150,000 mile warranty for this issue. According to gm, my particular VIN is not included in this recall. I am concerned as to how many other trucks are not included. This issue also cost nearly $4,000 for the repair.

Internal oil consumption. With no oil puddled or spattered under the vehicle at time of purchase from a dealership or since then, a dealer certified vehicle with afm at 153 miles from leaving the dealer the oil was non-existant on the dipstick. This directly indicates a TSB, techical service bulletin involving the cause of failed lifters causing internal oil consumption and damage to lifters, cam shaft, push rods, rings and possibly more. This is a common result of the active fuel management system which shuts off some of the cylinders for fuel economy for Chevrolet v6 and v8 engines. The problem was reported to the dealer by me imediately after the oil check at 153 miles and then towed to the dealer. As this is considered a catastrophic amount of oil loss, the vehicle could've been rendered inoperatable during operation in traffic and been a servere safty hazard. The dealer after initial inspection sent me a message that they think the problem is an undetectable small leak so they put some dye in the oil to check it. Which evades the actual internal consumption problem of 1. 5 to 2 or more quarts of oil lost in just 153 miles by that ratio that would amount to 13 quarts per 1,000 miles. And helps them stall for time, to try to run out the very short 3 month/3000 mile drivetrain warranty. There was noticable erratic engine performance and some shudder but that shudder may have come from the transmission. The odometer read was 115690 at purchase and 115843 when towed=153 miles driven from when the certified inspection was performed for a loss of 1. 5 to 2 quarts that I know of, it could have been much more oil missing. A suddenly inoperatable vehicle in town at intersections or on the highway at high speeds could be deadly for myself or others in traffic. I took and have videos of checking the dipstick to show it dry but it's an mp4 file which I don't see a place to upload it here. Available upon request.

Unknown. I have had issues with my vehicle since the purchase. Very subtle in the beginning, then it became more noticeable. There was a recall issue with a valve in the operation of the transmission, this issue is now affecting the shifting into different gears. The other day a vehicle ran a red light and my wife and I were in the intersection. I tried to accelerate to get out of the way, but here was a delay before the truck's transmission engaged. Luckily it did engage and the collision was avoided. This is a serious issue, an issue that shouldn't exist, an issue that the manufacturer knew about. I would like someone to investigate this and hopefully, help me with this issue. [xxx] [xxx] . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving under normal conditions and the vehicle began lurching, limiting acceleration, with an error saying "reduce acceleration". Was able to get home but the next time the truck was started there was a check engine light and the vehicle was unable to shift into reverse gear. When attempting to put it into reverse, it gives the error "conditions not correct to shift" and turn on the parking break. Trying to drive it with this issue is unsafe. The truck will lurch, limit acceleration, and overall not safe to drive. The truck only has 21k miles on it.

The contact owns a 2016 Chevrolet silverado1500. The contact stated that while driving at 48 mph and driving uphill, the transmission downshifted and started sputtering. The contact pulled into a parking lot and attempted to troubleshoot the failure, but the failure persisted. The vehicle was driven to an independent mechanic, where it was diagnosed with a torque converter failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 103,000.

Entire transmission failed and needs to be replaced.
