Power Train Problems of Chevrolet Silverado 1500 - part 1

Vehicle comes to a stop sign on a low pitch hill. Driver releases the break and presses the gas portal to drive forward and vehicle begins rolling backwards. Driver looks down at the dash and sees a “press start button” message. Driver pressed start button and hears the engine come to life. Driver releases the break and presses the gas pedal to accelerate. Vehicle rolls backwards again. Another message to press start. Driver presses start again. Vehicle is now in park and with the parking break engaged. Driver releases parking break, shifts to drive and is now able to leave the intersection. Issue causes risk of collision due to unexpected rollback. Service appointment schedule for 10/15/26. No warnings presented beyond the start message errors listed above. Newly purchased vehicle: 2026 model year. Appx mileage at time of incident: 122 miles.

On [xxx], at approximately [xxx], I was driving my 2026 Chevrolet Silverado 1500 rst (5. 3l v8, 4wd), leased new on [xxx], with about 122 miles on the odometer. I came to a complete stop at a stop sign on an uphill grade at [xxx]. The auto stop/start feature shut the engine off while I held the brake, as designed. When I released the brake to proceed, the engine did not restart, and the truck rolled backward down the grade. The instrument cluster displayed "press start button. " I pressed the start button, the engine started, and I released the brake again. The truck again rolled backward, and the cluster again displayed "press start button. " at this point, the vehicle was in park and with the parking break engaged. I pressed start a second time. I released the parking brake, shifted into drive, and was finally able to proceed. In total there were 2 failed restarts after an auto stop event, 2 uncommanded rollbacks on an incline, and 1 automatic parking brake engagement. No collision occurred. However, the truck rolled backward toward another vehicle behind it with no engine power, and I had to restart it twice while stopped at an intersection. This is a serious safety hazard in traffic, especially on hills. Gm has published preliminary information bulletin pit5689n, "no restart after an auto stop event / no crank," covering 2020-2026 Silverado 1500 trucks. It cites a loose or broken engine ground strap as a possible cause. This vehicle is 5 days old and the defect appeared within 116 miles of delivery. I am disabling auto stop manually at every startup until the vehicle is repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving down interstate about 65 the light on dash came on stated low engine oil stop engine at same time could smell smoke and saw smoke coming from under hood. I pulled over as fast as I could and by that time the smoke was pouring out from under hood. I turned engine off and I popped hood got out and slowly opened in case was on fire. It was not but I saw oil all over my engine and dripping from under vehicle. The front tire was covered with oil as well as down side of my truck. I saw where I pulled over a long oil streak. Oil kept leaking oil and large puddle formed under engine on side of road.

2021 silverado with 5. 3 engine/8spd transmission/38,000 miles just outside of the 5-year powertrain warranty current recalls under this VIN as of 10/07/2026* undiagnosed issues with symptoms similar to transmission or rear end slippage, torque converter or clutch pack problems. No warning lights or messages have appeared 1) vehicle seems to hunt for proper gearing between 30-40 mph (3rd to 4th gear) with light shuddering before shifting gears. Occurred 20+ times 2) sudden jerk when taking off from dead stop. Feels like being lightly bumped from behind then drives normally. Occurred 4 times 3) only noticed when towing appx 6,000lb trailer descending down a hill - a one-time loud clunk when easing off throttle and coasting downhill. The sound is similar to hitting a metal desk with a fist. Occurred 7 times. Spoke with local Chevrolet dealer who informed me the powertrain warranty has recently expired, and no repair cost would be covered. Recommended dealer service would be to replace the transmission fluid and filter with mobil 1, potentially reprogram the transmission, and replace the torque converter. All on a vehicle with only 38,000 miles.

These 6. 2 liters are failing and there is no fix. Gm claims my motor passed a test but not knowing if and when it will break down leaving me stranded or worse in a horrible accident with engine failure is not safe. My lane assist is now out as well, the version is old and gm wants to charge to update it (only 60k miles on the truck). Top it off with this new recall my oil changes are over $150 for supercar oil. The deprecation of this truck with know recalls is another issue. I can't get rid of this because it isn't worth much anymore. Do not buy gm or chevy!! so sad to see them fail their customer like this.

My 2019 chevy Silverado 1500 has only 61k miles on it. While driving at expressway speed I can feel a vibration, when at a stop and slowly accelerating it feels like driving on a rubble strip and then while going through the gears it has hard/harsh shifting! I have taken it to my local gm dealership in [xxx] and they are going to do a transmission flush and new fluid but I am worried that the problem may be worse than just bad fluid at this point, more like worn clutch plates, etc. ? if this does not fix the problem my extended warranty end at 80k miles and I will be stuck with a truck that has a major transmission problem! no trans should go at 60k miles! why isn't there a recall on the 1500 8 speed transmission for these chevy trucks? I understand there are many technical service bulletins issued by gm for the transmission issues but no recall. This should be looked into with all the complaints filed for their transmission issues! hopefully gm will be forced to do the right thing and issue a recall.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 25 mph, the vehicle unexpectedly shifted into park(p). The contact stated that during the failure, the instrument panel was blank. After restarting the vehicle, the transmission warning light illuminated. The contact stated that the failure recurred on several occasions while driving at slower speeds. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure via phone, and a case was opened. The approximate failure mileage was 26,355.

I am submitting this complaint regarding a 2021 Chevrolet Silverado 1500 trail boss 4wd with the [6. 2l v8 (l87)], VIN [xxx], 101,000 miles. The truck was assembled in mexico in xxx, about six weeks before xxx, just outside the build range of gm recall 25v-274 (n252494000, engine failure). On 10/2/2026, [xxx], [xxx] a certified gm dealership, diagnosed crankshaft and lifter failure, matching the recall condition. Codes: p0300, p050d, p0016. The truck was shaking violently, the esc and emergency braking system failed, reducing engine power. Gm's part 573 filing attributes the defect to out-of-specification crankshafts and identifies a mexico-based crankshaft supplier. I ask gm to confirm my engine's build date and crankshaft source. A six-week gap in build date should not exclude a truck with the same failure. Engine failure can cause sudden loss of power while driving, a safety risk. The dealer quoted repairs of up to $10,292. 00. I request: that gm cover the repair in full as a goodwill adjustment. That gm and NHTSA review expanding the recall population to trucks built near my date. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

"while driving, the vehicle experienced a sudden and complete loss of propulsion/acceleration due to internal failure of the 6l80 6-speed automatic transmission. The failure occurred without prior warning, creating an immediate highway safety hazard by leaving the vehicle unable to maintain speed in traffic. A professional mechanic diagnosed the issue as a catastrophic torque converter failure that contaminated the entire transmission system with metal debris, requiring a complete out-of-pocket rebuild. " this resulted in having to pay $4,800 plus tax in such a rough economy.

I was sent a notice of a recall regarding a fuel pump, power control module that needs to be taken care of, but it is not being accepted under my VIN number. I believe that there is this issue with my vehicle or something similar because every day I start the vehicle up for the first time and drive it. It is jerking me and does not have proper fuel or proper pressure to move the vehicle without jerking me. After 10 to 15 minutes it cleans up and drives better but then again we’ll redo it if I sit still for multiple hours and restart the vehicle again late in the afternoon it will do it all over.

On September 24, 2026, my 2022 Chevrolet Silverado 1500 (5. 3l v8, 10-speed automatic) suddenly stopped moving and the steering locked. The truck had to be towed to the Chevrolet dealer. This is a repeat failure. On June 17, 2026, at about 43,700 miles, the truck showed the warning "service transmission now / unable to shift soon" with code p07b4. The dealer ordered part 86277653 (automatic transmission shift control assembly), which was on backorder for weeks. Between June and September the truck was in the shop several times for the same problem and was returned to me as fixed. On September 24 the same failure came back, this time with loss of drive and locked steering. A truck that can suddenly lose drive and steering is a crash risk. The problem has been confirmed by the dealer. The vehicle has been at the dealer since September 24 and it is still not repaired. The complaint has been reported to gm customer assistance.

I was traveling at 65 mph when my truck engine shut off, put itself in neutral, asked me to push the start button. And then the screen went black. Would not go into neutral for a tow. Taken to dealer where I purchased it from. Was told that the motor is seized.

The vehicle intermittently experiences transmission or drivetrain slipping, shuddering or juddering, and shaking while being driven. The symptoms are inconsistent and there is currently no check-engine warning light. The problem has not yet been diagnosed or confirmed by a dealer. I am concerned that the condition could worsen and cause loss of propulsion, unexpected shifting, or loss of control. The vehicle is equipped with a diesel engine and is within the model family described in NHTSA recall 24v-797 involving transmission control valve wear. The vehicle and affected components are available for inspection upon request.

While driving at about 20mph we hear a grinding noise and the truck throws itself into nuetral and then shut off. The truck seems to be on like when started with the key fob, on but not fully started. A warning message comes on the dash stating "conditions not safe to drive". The truck would not go back into gear, even after pressing the start button and truck regaining power. Pressed on the brakes to stop, put in park and then back into drive. Message warning went off and truck drove as normal again. This has happened twice since purchasing the vehicle in may 2026.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle previously had a bell housing installed to catch internal metal shavings; however, the housing assembly failed again and needed to be replaced. The vehicle was taken to a dealer for a diagnostic test. The contact associated the failure with the torque converter. The torque converter was previously replaced once. The contact stated that while driving, the vehicle felt like it was driving over rumble strips or speed bumps, which the contact felt and heard. The manufacturer was notified of the failure. The dealer was unable to duplicate the failure. The failure mileage was 60,000.

The contact owns a 2019 Chevrolet Silverado 1500. While driving at an undisclosed speed, the low engine oil warning light illuminated. A month later, while driving 60 mph, the transmission malfunctioned between 4th and 5th gear, either missing shifts or shifting erratically, accompanied by a severe vibration. The vehicle was taken to a local dealer, where technicians discovered a leaking engine oil cooling line while preparing to repair the transmission. The dealer confirmed the failure. The manufacturer was notified of the failure; however, the contact was informed that the VIN was excluded from customer satisfaction program: n192220080.

The specific cause has not been identified. On xxx6, my 2025 Chevrolet Silverado 1500 custom lt trail boss unexpectedly rolled away while parked and unoccupied, striking another parked vehicle. The truck remains at modern Chevrolet and is available for inspection. Gm/esis opened a safety and product liability investigation and is arranging inspection/data retrieval. I parked at walmart in [xxx], shut the truck off, exited, locked it, and walked away. Shortly afterward, I heard a sound resembling the key-fob-left-inside warning. My key fob was in my pocket, so I returned and saw the truck moving with no driver. Another person and I tried to stop it. I entered through the driver’s door and pressed start/stop several times, but it would not start while moving. It continued moving and struck another parked vehicle. Vehicle dropped off on xxx and modern Chevrolet could not reproduce the incident or identify the cause. The service advisor stated it “came out of gear but don’t know why” and escalated it to gm. Gm/esis plans to retrieve sdm/airbag data, and I requested any tech ii/mdi scan data. No warning lights, messages, or chimes were observed during the incident. I did not see/hear “shift to park,” and I was able to lock the truck with the key fob outside. In a later controlled test, I left the truck in drive and shut it off. It displayed “shift to park” and sounded a warning chime. Opening the driver’s door also produced a key-fob-left-inside-type alert, which did not occur on xxx. The truck did not automatically shift to park or engage the electronic parking brake and slight movement was felt during the test. No further testing occurred by me after xxx. I have also experienced infotainment freezing after software updates and random electronic parking brake application when shutting off, and remains engaged after restart. The truck received an oil change/tire rotation at modern Chevrolet on xxx. Cause still remains unknown. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These duramax 3. 0 diesel engines are also a huge problem with the emission system and def. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [xxx]. I had to rent a vehicle to drive back home to [xxx]. The dealer has no idea how long it will take to get a shifter from chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Got my truck back yesterday from in shop for 2 weeks from being repaired. Got to red light just stopped my engine shuts off. Dash shows engine/transmission problems. Exact same thing happened two weeks ago. Had to get towed into dealer again this am.

Vehicle has a bad valve body which was confirmed by the dealer. Driving down the street and the engine went from 3 to 4 gear and the rear wheels locked up. Also when coming to a stop the truck jerks so bad it snaps your neck. Gm has major problems with these trucks and knows the problems and keeps issuing bulletins however they have a massive backlog of orders for parts to fix these trucks which leaves people's trucks sitting at service centers for months waiting for backordered parts.

The contact owns a 2020 Chevrolet silverado. The contact stated that while driving between 20 mph and 60 mph, the vehicle shudders a lot while accelerating. The vehicle was taken to an independent mechanic where it was diagnosed with a failure in the transmission. The contact stated he contacted a dealer where they confirmed the failure but stated there are no recalls nor tsbs related to the failure, although there are recalls for different model vehicles that have the exact same transmission as the contact's vehicle. The contact referenced TSB 19-na-121 (powertrain); however, the VIN was not included in the repair. The contact stated he could feel the shaking shuddering. The manufacturer was notified of the failure. The vehicle was not repaired.

Traveling on interstate highway at 70 mph when the truck engine went to idle and transmission tried to go into park. The dash just flashes "service transmission" and and other warnings. Engine still runs but can't shift out of park. Shifter is not responding to move the truck. Engine can't come off idle. Turn off engine. Power button will turn power on or off but won't crank engine. 4 ways flash for awhile with dash flashing then everything go blank. All electric power is lost for awhile and then dash starts flashing and 4 ways start flashing for awhile. This cycle keeps repeating. Truck has to be loaded on a truck to tow away. This is the 3rd time is has done this problem but at lower speeds before. Dealer can't find the problem yet.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving 40 mph, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the transmission was slipping while shifting gears and the transmission was shuddering. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact was informed that the parts were ordered. The manufacturer was contacted by phone and made aware of the failure, and a case was filed. The contact was informed that the warranty had expired five months prior. The failure mileage was approximately 53,020.

Rear axle locks up and transmission goes into limp mode , this happens when slow speed under acceleration, this happens almost any time in traffic , at stop light , acceleration to freeway. A safety issue, shows a p0700 code and p2729 code , engine service code light goes on , t/c and skid lights. Also happen at hard brakes in traffic lights or fast slow downs.

Have notice that the car jerks hard from time to time and when try to accelerate the car does a quick/short stop then accelerates hards very jerky. Also I smell coolant and my check engine light came on. .

Transmission is shuttering and rpm fluctuates up and down Chevrolet dealership says the torque converter goes out on the trucks all the time mine is at 84000 miles they say its a common issue.

I am filing this complaint regarding a serious engine lifter/active fuel management (afm) failure in my 2015 Chevrolet Silverado 1500. The vehicle experienced a lifter failure that caused significant engine problems and created a potential safety concern while driving back from shopping: loss of power, engine misfire, severe shaking, ticking, check-engine light, stalling, inability to maintain speed, etc. The vehicle had approximately 200k miles at the time of the failure. The vehicle was inspected by a local mechanic, which diagnosed the problem as collapsed/failed lifter. The repair required/will cost approx. 3k or more estimated my concern is that this does not appear to be an isolated failure. Other owners of 2015 Chevrolet Silverado 1500 trucks equipped with gm's active fuel management system have reported lifter failures, including failures resulting in engine damage and sudden loss of engine power or propulsion. A sudden lifter or related engine failure can create a significant safety hazard, particularly when it occurs at highway speeds, while merging into traffic, crossing an intersection, or in another situation where the driver depends upon the engine to maintain acceleration and vehicle speed. I am reporting this in hopes that gm can be held accountable as they knew about these defective lifters but did nothing but hide it.

Transmission entered limp mode when decelerating at highway speed. Shutter shift, rapid rpm increase. First shift in the morning is a hard shift with loss of power.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving, the vehicle was rumbling and shaking abnormally. The vehicle was towed to a dealer where a diagnostic test failed to retrieve a fault code. The contact agreed to pay an additional fee to have the transmission pan lowered to see what had caused the failure. The mechanic discovered metal shavings inside the transmission pan. The dealer stated that the transmission pan could be cleaned and reinstalled; however, the dealer refused to provide a warranty for the repair or guarantee that it would fix the vehicle. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

While operating at highway speeds this truck lost all engine power and would not start back up. Vehicle was towed to local dealer and determined to be a catosrophic failure of the crank shaft. Repairs are being made as covered under warranty.

Came off the parkway and came to a stop at a stop sign. As I attempted to accelerate forward the truck shuttered violently, did not move forward and then slammed into gear. As it slammed into gear it jerked forward. The force of the jerk pushed me back in the seat and caused the steering wheel to turn. About 100 yards later I came to a stop in traffic. As I attempted to accelerate the same incident occurred again. After the second incident anytime I same to a stop and attempted to accelerate forward the shutter was no longer present but the truck would not move at first and would then slam into gear and jerk violently. This would occur in drive and reverse. I brought it to the dealership and they diagnosed that it needed a transmission. The service writer even told me it bucked so hard while the technician was moving it that it almost put him through the steering wheel. The truck is currently having the transmission replaced at greenbrook GMC. Estimated repair cost is $9400 plus taxes and fees. Can provide invoice and bill once repair is completed.

Vehicle is hard shifting and has the following error codes. Engine p0700 transmission control moduel requested, test not passed transmission p0747 transmission control solenoid valve 1 stuck on- test failed. Warning indicator requested. Very concerned to be driving this vehicle.

I had the 6. 2 engine replaced at 38k miles. Now at 78k miles my new engine replacement is using 1. 5qrt of oil within 4k miles. I am being told I have to watch the oil every 800 miles and report back to Chevrolet. I feel my investment is completely a loss of $60,000. 00 + . I was told by the service tech that I will probaly have to have another engine replaced again. . My resale value is no where near worth anything and I am stuck.

I am submitting this formal statement regarding a severe, recurring safety hazard involving sudden engine stalling and internal mechanical noise on my 2026 Chevrolet Silverado 1500. The vehicle has experienced multiple sudden engine stalls during low-speed deceleration, specifically while letting off the accelerator pedal to execute low-speed turns into parking lots. When the stall occurs, the engine dies completely, causing an immediate and dangerous loss of power steering and power braking assistance mid-turn. Because the vehicle shuts off completely while still in motion, I am forced to bring the truck to a dead stop, shift the transmission out of drive and into park, and completely cycle the ignition system to restart the engine. There is a distinct, audible mechanical ticking sound coming from the engine compartment during operation. Crucially, the vehicle has never illuminated a check engine light, displayed a dashboard warning message, or given any advance electronic indication prior to or during these sudden stalling events. This vehicle's build window falls directly into the scope of the national highway traffic safety administration’s (NHTSA) active engineering analysis (ea26005) investigating catastrophic valvetrain and engine failures on gm 6. 2l l87 engines. Because this defect causes an unexpected loss of vehicle control with zero diagnostic warnings, it poses an immediate highway safety risk to myself and others. I request a full diagnostic scan for hidden or pending fault codes, a physical inspection of the valvetrain/dynamic fuel management (dfm) system, and an inspection of the engine oil filter for metallic debris indicative of internal bearing degradation.

Multiple instances of engine shutting off while driving and switches to "park". Most recently the truck suddenly lost power, shut off, stopped immediately, went into park, jerked extremely hard, and displayed the message “service transmission. ”.
