general problems of the 2024 Chevrolet Silverado 1500 - part 1

Oil cooler failed and truck was at dealer for a month over winter. Now June 20th transmission failed and there is no timeframe on the valve body. I am still making payments on this truck and no dealers have a timeframe.

Complete engine failure on the highway, compete engine and power lockup, towed back to dealership where complete engine lockup was confirmed. No prior issues, no other damage contributing to failure. Claims not to be covered under current recall, advising the recall be extended to all 6. 2 19-04 chevy models as I experienced the same engine failure as recall states.

On [xxx], I was going to atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of may, I took the truck to allen turner in pensacola, florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet dealership, which was also closed. On today [xxx], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

5/4/26 traveling at highway speed when motor quit, would not restart. Spent additional funds $682 having towed back to selling dealer in my hometown and a rental car. Dealer reports motor seized and will be replaced. As of 6/9/26 dealer reports no information available for timeline on receipt of new motor to replace.

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes p0700 (transmission control system malfunction) and p0717 (input speed sensor circuit no signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "reduced power / limp mode. " this creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision. The malfunction has been repeatedly confirmed and documented by authorized gm service agent rountree moore Chevrolet (lake city, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including transmission control module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from general motors inspected it outside of the local dealership level. The failures are consistently preceded by an illumination of the dashboard check engine.

While driving, the truck suddenly boggs down and gets sluggish. A message appeared once that said reduced acceleration drive with care. It is dangerous because it loses power and stalls in front of other vehicles. I took it to the dealership on Friday the 17th and they said it was the crank position sensor. They ordered the part and I took it back on Monday the 20th and they replaced the sensor. Today, while driving down the highway it did the same thing again. I will be taking it back to the dealership tomorrow. The truck has 26,000 miles on it.

Transmission- lost reverse and some forward gears too. Without any warning signs and no check engine light until hours after. It is going into the dealership on Monday (4/20) and this all happened on (4/17/2024).

Driving 70mph on the interested, the vehicle put itself in neutral. I pulled over and turned off the engine. I started it back up then it stalled at the next stop light. It would not turn back on. It had to be towed to the dealership. Turns out it was the 6. 2 engine recall issue. It has been in the shop for 5 weeks and still waiting on repair parts.

On 04/03/2026 at approximately 0545 I was heading in to work . While at a complete stop I proceeded to accelerate on the highway 54 brf WI. 54615 when the truck made a clunking noise and jerked. At which point the engine light turned on along with reduced speed message across the display screen. Unable to pull over safely at the moment I had to proceed no faster than 25 mph on us 54 hindering all traffic behind me. Once safely pulled over I placed the truck in park, then neutral , which made a loud clunking noise and absolutely no reverse. Truck towed to local dealership. Vehicle had been inspected by dealer tech. Tech stated faulty valve body in the transmission.

The 6. 2l v8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. Gm has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor.

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.

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.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home. (this part of not going in reverse I do have on video) once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

I was driving down the highway and the vehicle suddenly shutoff without any warning. I coasted down an off-ramp and came to a stop in the middle of a round about. The vehicle would not re-fire and had to be towed to dealership. When at dealership it was discovered the engine failed. This is a 2024 6. 2 liter engine that was not included in recall. I could have caused an accident on the highway as I suddenly lost power. People who were included in this recall received a 10 year 150k warranty on the new engine. My truck should be included in that.

On 1/31/2026, while returning from an akc event with my xxx year old border collie, I was traveling on ixxx at approximately 70mph in the left hand lane passing other traffic. As I started up a hill in a remote area, I began to hear a knocking sound coming from the engine compartment that sounded like a rod knocking and the truck began to struggle to continue up the hill. It then lost all power, a message stating to shift to neutral and restart flashed on infotainment screen, I shifted to neutral and pushed the start button, but everything went blank. I had to struggle to merge back into right lane and eventually over to the breakdown lane, approximately 5 miles from the nearest exit. I was forced to remain on the side of a busy interstate for approximately two hours during an unusually cold day for florida that consisted of snow flurries while waiting for roadside assistance. Luckily, I was able to arrive at the dealership 5 minutes before closing and was able to get my truck checked in. The service writer knew exactly what the likely issue was when I described my ordeal, and it was partially confirmed when she pulled the christmas tree of codes from the computer that my truck was throwing. It should be noted that the truck would not restart after the catastrophic failure that stopped the motor at 70mph on the interstate and would not shift to neutral for the tow truck operator to load or unload onto flatbed. Subsequently, techs determined that engine failed due to suspected internal damage to crankshaft and motor was replaced under warranty along with torque converter. The failed engine serial number was [xxx] but I was never notified or included in current recall 25v274, it did not show as active recall in gm app nor was it inspected during lof visits at various gm service departments. My truck was in gm service from 1/31 - 2/21 for the engine replacement, mileage on 2024 Silverado 1500 high country was 25,274 at failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(.

Transmission failed at 15000 miles. Attempted to shift to reverse and instead car went into neutral. Allowed me to shift into forward but quickly went into “limp mode” once underway. Seems like the same issue as many similar gm trucks have had with transmissions but my 2024 is not included in active recalls when searched by VIN. Suspect it probably should be since issue appears to be the same as those that are.

Truck was purchased Aug 2024 during first few months, I felt a shudder/vibration when either holding speed and/or slightly accelerating between 30-45 mph, usually at 1100-1300 rpm. Current odometer 33,995 in the last month the truck has began to vibrate worse. I have a "rumblestrip" feeling when at the same speeds. More noticeable on surface roads when following behind traffic at 30-45 mph. Generally the shudder is felt at approx. 1100-1300 rpm. Took the truck to the dealer yesterday, and they performed a quick roadtest. Service tech was able to feel the rumble strip shudder multiple times, however their diagnostic tool only indicated a tcc slip 2 times during a 20 min drive. The shudder/vibration happens when in "d". It is not present in "l9", or in "tow mode". The shudder feels worse in 4wd. If the shudder/vibration is happening, I am able to hold the speed and rpm at the current spot, the sensation is continuous and does not go away unless I accelerate or decelerate. I tend to feel it more when on an incline, and decelerating. As or right now the data has been sent to gm for diagnostic viewing. Found multiple TSB for issue with 2500/3500 models, and 1500 models from prior years. L84 engine - 2024 Silverado 1500 rst.

Hard/delayed shifting, slipping, shuddering , like rumble strips at certain speeds. Jerking, bucking, or significant delays when shifting gears. Shuddering/vibration: a feeling like driving over rumble strips, especially at certain speeds and when warm.

After engine blows due to recall and engine not running, it is impossible to shift the electronic transmission into neutral mode for towing. This happened to me in November of 2025 and I was recently told that I should report the issue. Neither the tow truck operator nor myself were able to get the vehicle into neutral without the engine running. I could have easily been stuck in the middle of traffic and no one would be able to help me move to a safe location. Some way of easily getting the vehicle into neutral without the engine running needs to be added to all silverado’s with electronic transmissions.

The coolant control valve and the transmission control module are having to be replaced on thousands of Silverado 1500s from 2022 to 2025. Both parts have been updated, but there is no recall and many people are being left stranded due to this. Mine has not currently failed, but I am older and really don’t want to get stranded due to a known issue. Why wouldn’t they have been forced to do a recall general motors should be replacing these as a preemptive precaution.

Hairline crack developed on the transmission cooling line at the connection of the thermal bypass block. After looking up it seems to be common. Yes, there have been user-reported issues with transmission cooler lines leaking or cracking on 2024 Chevrolet silverado models equipped with the 3. 0l duramax diesel engine, including at or near the thermal bypass block connection. These reports primarily come from owner forums and appear to affect a subset of vehicles, often discovered during routine maintenance or after noticing fluid spots under the truck. Symptoms can include hard shifting, fluid seepage on the undercarriage, or low transmission fluid levels, with some cases progressing to require towing if not addressed early. For instance, multiple owners of 2024 Silverado 1500 models (including zr2 trims with the lz0 3. 0l duramax) have described leaks originating from the cooling line block or thermal bypass area next to the oil filter, sometimes involving hairline cracks in the lines themselves. ? in one detailed account, a 2024 model with around 35,000 miles experienced fluid leaking from the cooling line block, leading to replacement of seals and the entire line assembly due to cracking discovered after initial repairs. ? similar problems have been noted on closely related 2023 models, where leaks at the thermal bypass valve necessitated replacing the valve, o-rings, and all cooler lines, with some users reporting hairline cracks as the root cause. ? parts like the lines have been on backorder in some cases, causing repair delays, and resolutions are typically covered under warranty (e. G. , powertrain coverage up to 100,000 miles), though repeated visits to dealerships are common. These issues seem tied to the 10l80 10-speed transmission paired with the 3. 0l duramax, where the thermal bypass valve can contribute to overheating or fluid flow problems if faulty, potentially exacerbating line wear.

Complaint description on Tuesday October 28th, 2025 while driving to work, my 2024 chevy silverado ltz suddenly went into limp mode during normal driving. The truck would not go into reverse at all. I had to use onstar to call a tow from my residence because the vehicle was not safe or able to be operated. The truck has been at the Chevrolet dealership since that day and as of today (November 7th) it still has not been repaired. The service department confirmed it is a failed transmission valve body. Research shows this is a recurring and known issue on many gm trucks and gm does not appear to have a permanent fix yet. Component/system that failed: transmission valve body failure. Component is currently located at the gm dealership and is available for inspection. Safety risk: this failure caused sudden limp mode, loss of power, and inability to reverse while in active traffic. This put my safety and potentially other drivers at risk due to sudden unexpected deceleration and inability to maneuver safely. Problem confirmed: yes. Confirmed by gm dealership service technicians. Inspection: the vehicle is currently at the gm dealership. No manufacturer field rep, insurance, or police inspection has occurred yet. Warnings / codes present: the failure occurred without prior early signs that morning. When it failed, onstar diagnostics reported: p2732: transmission system — “engine and transmission system not performing as expected. ” p0700: transmission control module requested malfunction indicator lamp illumination. Emissions related dtc set in the transmission control module. Both codes triggered at the time limp mode activated. Best assessment: this appears to be an ongoing recurring gm transmission valve body issue affecting newer gm trucks. The failure caused a sudden loss of drive capability and is a safety hazard that requires NHTSA investigation.

8 speed transmission without any warning, started shaking and clunking and slipping while doing 55mph in traffic causing sudden loss of momentum. 8 speed transmission failure. Dealership says bad transmission control module and won’t inspect internal components. Chevy is still playing games with people with their defective 8 speed transmissions. They have not fixed all of their previous problems.

2024 chvrolet 3. 0 diesel is losing oil at 3k miles on every oil change. Dtc p06dd , dealership did an oil consumption test, they have determined there is signifcant oil loss after every oil change after 3k miles. Truck is at 71k miles. Engine power loss while driving, check engine light on, drove straight to the dealership.

Truck did not have reverse. Service engine came on after going forward and possible loud shudder like going over a pot hole. Not sure if it was a pot hole or transmission. Dealer fixed the valve body in transmission after 1 week.

For the first time I purchased a brand new vehicle off a dealership lot…what a mistake. While the dealership itself was an awful experience I thought it was worth it for a chevy silverado. After all my previous one was so reliable. Wrong. The first issue I found was I was unable to shift into reverse to back out of the driveway of a fire station I volunteer at. After driving forward a couple times and shutting the vehicle off and shifting multiple times I had to be towed out in reverse. I was able to drive home but the transmissions slipped once and the vehicle slowed abruptly. The check engine light was now on. I dropped the vehicle off at the dealership over the weekend and on Monday they called and informed me the 2024 silverado misfired once and nothing was wrong with the transmission. There was nothing they could do. About two months later I was driving to work as a career firefighter/paramedic when my vehicles check engine light came on and a message informed me that I was in “reduced acceleration mode”. I slowly and carefully made my way to work and brought the truck to the dealership after my shift. The check engine light was now on again. They informed me later that day that I had a faulty valve body in my transmission. They “unfortunately” could not give me a completion date on my repair as they had no eta for the replacement part. It appears the part is in high demand. This makes sense as a quick google search shows this is a widely known issue with the 10 speed transmission. So far I have been unable to get a rental vehicle between the dealership and gm. Aside from my house my 2024 silverado is the largest purchase of my life. And at 15,000 miles I am without it for the foreseeable future. As a first responder the communities I serve depend on me to respond from home at any hour. My family and I are living in a diy renovation while also starting a farm business. I need a dependable vehicle and regret spending $53,000 on a new vehicle. I have more to say.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, the vehicle lost power and then stalled. The vehicle was restarted after each failure. The check engine warning light was illuminated, and the message "reduced acceleration - drive with care" was displayed. The vehicle was taken to a dealer on several occasions, and the dealer retrieved dtc: p2732 and p0700. The contact was informed that the valve body needed to be replaced, and the transmission was leaking transmission fluid, but the leak was not located. The valve body was repaired, and the transmission fluid was topped off, but the failure reoccurred 2-3 months later. The manufacturer was not notified of the failure. The failure mileage was 10,900.

Component: faulty "coolant control valve" causing reduced acceleration, and check engine light. Fan is constantly on. Safety: can overheat, reduced acceleration can cause accident. Problem reproduced: dealer did check/confirm codes and errors warning messages: no warning or messages prior.

Experience hard shifting into park from a stopped position a week or more prior to incident. While driving, several hard shifts were experienced which resulted in the vehicle unable to surpass 30 mph. Cel illuminated displaying codes: p0747 and p0700. Suspected transmission valve body issue. Vehicle was towed to dealership that it was purchased from.

Lost the high gears on the interstate. Had keep it under 60 to keep rpms under 4000.

Component/system failed: power train – specifically, the #6 lifter failed and is available for inspection upon request. Safety risk: the failure caused noticeable engine misfiring, loss of power, and abnormal ticking sounds, which could potentially lead to engine stalling while driving. This creates a serious safety risk, especially during highway driving or merging situations. Confirmation of problem: the issue was confirmed by a certified gm dealership technician, who diagnosed the failure of the #6 lifter. They advised that the lifter and potentially the camshaft need replacement. Inspection: the vehicle has been inspected by the dealership service department. No inspection has been conducted by police or insurance at this time. Warning signs: prior to failure, there were no warning lamps. However, the vehicle began exhibiting a noticeable ticking noise followed by rough idling and reduced performance approximately 71,000 miles.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, there was an abnormal burning odor entering the cabin of the vehicle, and the rear windshield shattered, with white smoke entering the vehicle. The transmission and engine warning lights were illuminated. In addition, several unknown messages were displayed on the instrument panel. The contact pulled over to the shoulder of the road and the vehicle was towed to a local dealer for further investigation. Prior to the failure, the vehicle was taken to the same local dealer where the os sensor was replaced. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 23,000.

New police vehicle on the road for only two months with only 6030 miles on it. Check engine light came on vehicle lost all power, no reverse, transmission would not shift. Warning came up about decreased acceleration. Managed to get vehicle to dealer, computer scanning stated that transmission valve body failed.

When in normal drive mode, an unexpected or accidental bump of the transmission t-handle shifter between the seats towards rear of vehicle while at a stop sign or parking lot, etc. Will "lock the transmission in low gear 1 out of 10 available gears". If one pulls out into traffic without noticing this event, the engine will approach redline without shifting into the next gear until the situation is acknowledged and the t-handle is one again pulled back to reset it into automatic drive mode. This is frustrating and potentially dangerous if the situation is not recognized quickly. I suppose engine damage could be at risk. There is "no save the engine by automatically selecting the next gear if this condition happens. There is also no lockout requiring the t-handle shift button on the side requiring to be pushed to acknowledge the desire to set this mode". I tested similar settings on Honda pilot and it does upshift even if in this manual mode to protect engine and occupants from this difficult situation. I personally will no longer allow any others to drive my truck until this situation is remedied. It appears to be dangerous to me and my truck for those who have no idea this can occur. Please try it for yourself. Vehicle must be similar to 2024 silverado high country w t-handle shifter between the seats. My hope is an over the air update can remedy this situation.

Valve body needs to be replaced. The truck is still under warranty. I have taken it to the dealership, they ordered the part and told me it was safe to drive in limp mode. I've since been waiting a month for the part to come in without a replacement vehicle. I can't drive to work and am losing quite a bit of business. There is a valve body in stock 97 miles away and gm will not ship it to my local dealer or help me in any way. The truck will not make it 97 miles for the repair. The check engine light stays on for a few days and goes off. I can only drive about 10 miles before it goes into limp mode and the dash will tell me I have reduced acceleration and to drive safely. As far as the safety of me and others unknown. The dealer has confirmed there is an issue but insists I continue to drive it even though I'm damaging the transmission.
