general problems of the 2023 Chevrolet Silverado 1500 - part 2

Vehicle vehicle is shuddering while driving at speed limit as well as accelerating. Based on research, it is apparent that there is an issue with the torque converter in this year model of truck. I have found more than 50 individuals online who have dealt with the same issue.

While driving at low speeds with light acceleration, the truck seems to sputter. When activating trailer mode this issue stops leading me to believe there is an issue with the torque converter. By searching forums, this seems to be a known issue with these vehicles. With it being as widespread as it is, I fell like this constitutes some sort of recall or customer satisfaction type of action.

I was driving on the highway doing 75 and the truck started jurking and slowing down by itself and getting loud. The display stated reduce speed and the check engine light came on. .

Engine light keeps returning after dealer visits for oil change. Exhaust heat shield rattles since day one of ownership. During normal commute, when I accelerate reduced power comes on and doesn’t allow me to accelerate much. Engine electrical system, including the charging and starting system. Checked battery, alternator, and starter.

The vehicle has been exhibiting occasional hard shifts over the last 2-3 months. Over the last 2-3 weeks the frequency has increased. While operating the vehicle at approximately 30 mph the rear wheels temporarily locked during one of these events while my wife was operating the vehicle. There was no indication that this was going to happen and no indication after the event. We took the vehicle to the dealership where they performed a diagnostic but found nothing wrong. In the week since picking up the vehicle I have been operating it. I experienced two occasions where upon trying to accelerate at approximately 30 mph there was a severe jolt that caused the traction control warning light to flash. This was under minor acceleration just to maintain speed when going uphill. There was no indication prior to the event and once it had concluded the lights went off. I also experienced an occurrence of the rear wheels locking temporarily. I was traveling at approximately 40 mph on flat ground and gently stepped on the accelerator to maintain my speed in traffic. The rear tires locked for 1-2 seconds to the point the tires were squealing and you could smell burning rubber. There was no indication prior to the event that it was coming. Given my necessary reaction I was unable to see if there were any indicators or warnings present. Following the event there were no indicators illuminated. Outside of these events the vehicle seems to operate normally. It runs well and generally shifts smooth. However, the rear wheels locking up unexpectedly presents an unacceptable hazard that is not resulting in any evidence that the dealer can use to troubleshoot.

Engine coolant valve failure causing vehicle to go into reduced power mode while traveling on highway causing vehicle to travel at a slow unsafe speed in relation to other traffic. Check engine light activated, reduced power activated. Chevrolet dealership confirmed engine coolant control valve issue. Engine control valve must be replaced before vehicle can be driven. Engine coolant control valve is on back order. No part replacement time frame due to back order. Safety concerns with reduced power mode on roadway with speed limits greater than 45 mph.

Vehicle check engine light came on and message displayed on dashboard indicating (loss of power) the transmission fluid temperature rose from 140* to 190* in seconds with vehicle coming to a complete stop while driving when trying to accelerate the vehicle it won't move but the engine rpm's were staying between 3 & 4 when accelerating.

The fuel pump went out, left me stranded and was replaced the transmission went out and was replaced. The lifters in the engine were replaced. When will the engine recall be addressed/acted on? the "cure" to install heavier engine oil is a very bad "bandaid". . . . Truly masks the problem. Maybe the chevy ceo should return her 2024 $25mm bonus to help pay for the repairs.

This truck has a problem where at low speed while turning left the engine surges and the truck speeds to 15 miles an hour unless I jam on the brakes . This started just turning left and now its starting to happen turning right . I had this truck to koons chevolet two or three times for this problem but it still persist to happen. This vehicle is dangerous.

The vehicle shots forward after some delayed acceleration.

Transmission has a stalled while driving car.

I have an 2023 l87 engine that could stop functioning at any moment. I'm retired and bought this vehicle as my last truck. I don't feel safe driving it on long trips which is why I bought it. Also the transmission shifts rough from 1st to 2nd when I accelerate. When I inquired about the transmission problem at the dealership the showed me a letter sized notice saying this might be a problem. But I was not notified about this when I purchased the truck. I would prefer to just return the truck as I have it financed with gm financial with no money down and am willing to just eat what I have already paid to get out of this ticking time bomb which I'm not comfortable driving long distance as [xxx]. Please advise. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving 55 mph and towing my boat on a 2 lane paved road , I started up a slight incline and the transmission downshifted so hard that the rear wheels locked up long enough to throw us into the dash even with seat belts on. I turned around an drove back home with it locking up again. No codes or lights on the dash. Took it to dealer June 26,2025 for dealer to diagnose issue. They kept it overnight and drove it about 60 miles, called me the next day to pick it up saying they could not duplicate the rear wheel lockup and since there were no codes there was nothing to fix. Tried to tell me it was my boat trailer causing the issue. Boat trailer has surge brakes, nothing electrical on trailer brakes. Over the next couple days the rear wheels locked up 2 more times. Always as I started up an incline going around 50-55 mph. No lights or codes July 2, 2025 we recorded on video 2 rear wheel lockups with the second lockup starting a slight fishtail on dry pavement and leaving a 5 foot skid mark. Went back to the dealership with the video and they said again if there are no codes they can’t fix it and they would try to duplicate the issue for me to leave the truck and not give me a rental vehicle , and no timeline on how long they would try to duplicate the issue. I did not leave my truck there and they kept promising to call me when they had a loaner vehicle for me to use. On July 14, 2025 ,while still waiting for a loaner vehicle the transmission finally locked up the rear wheels and check engine light came on. My mileage was 43078, it took 1,193 miles to finally throw codes that the dealership would fix. Codes were p0700 and p0747. These are same codes for safety recalls n242454440 and n242454441. Obviously my VIN is not included in the recalls but the dealership should have put the software on my truck the first time I was there on June 27th, the same day they completed the PA. State inspection on my vehicle. I wouldn’t have had to experience this unsafe conditions.

The vehicle is now at the dealer for the second time regarding transmission shifting issues. First visit I was told they can find nothing wrong despite my experiencing transmission slipping, loud clanking on shifting, and severe jolting when shifting. While having a travel trailer hitched to the truck after the first visit, I experienced all the same issues with the addition of transmission overheating warnings on the dashboard and near complete stoppage of the vehicle at highway speed. The same dealer now says the transmission "valve body" is defective and is being ordered. Due to towing a trailer with this truck (much lighter than rated capacity) I have the transmission fluid changed on nearly every oil change. The transmission filter has been changed on the recommendation of my mechanic, strictly due to quantity of fluid changes.

Driving down the city street the vehicle shuttered, the message "reduced acceleration drive with care" message appeared. Engine rpm increased. Transmission unable to change gears. Only park, reverse, drive (seems to be low gear). Then "service transmission now unable to shift soon" message appears. Now waiting on value body replacement parts. This is a known issue with over six month wait for parts across the nation.

Everyone I know that has this trucks has had transmission problems now mine is say selanoid is stuck in transmission but it throws a new code every time same issue.

My throttle body went out. Horrible shifting and wheel lockup.

Accelerating getting onto the highway, at about 65 mph I heard and felt 2 clunks and I lost propulsion. I made it to the side of the road and the vehicle went completely dead. I tried restarting it and it wouldn’t do a thing.

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.

Valve body failed - truck currently at dealership the valve body failed as I was pulling out of a gas station - emergency brake immediately engaged and kept re-engaging as I was trying to make it across the street into the parking lot. Truck could not go more than 5 mph and I was stuck and almost hit. Problem has been confirmed by the dealer after it was towed directly there. Unknown if component has been inspected outside of service department. Truck initially would not remote start using key fob, but then made it to gas station fine without any further symptoms. After gas station, car started severely shaking then emergency brake engaged and would not accelerate.

Over the past 4–6 months, the transmission in my 2023 Chevrolet Silverado 1500 has repeatedly failed in a way that creates a serious safety hazard. On multiple occasions while driving at highway speeds, the transmission has locked up the rear end, causing a sudden and violent loss of control. These incidents nearly resulted in collisions and could have caused serious injury or death. The truck will no longer shift at all and is now completely inoperable. These failures happen without warning and present a severe risk of total loss of vehicle control. Date(s) of incident: multiple occurrences between approximately March 2025 and August 2025 (exact dates unknown). Dealer / manufacturer response: I contacted Chevrolet customer care and multiple Chevrolet dealerships in my area (including john megel Chevrolet, dawsonville, GA). My most recent case was closed without resolution. I have been denied a loaner or reimbursement for a rental vehicle, and I have been told that the repair could take at least a month before even being assessed, with additional delays for parts. Consequence: this is not only a serious safety hazard but also a severe financial and employment hardship. I rely on this truck for my job, and without it, I cannot work. I am now three months behind on my truck payments and other bills, and I am on the verge of losing my job because I have no transportation. Gm’s failure to repair or provide alternate transportation has left me stranded, financially unstable, and at risk of unemployment — all while the vehicle remains under an extended warranty. Request to NHTSA: I am requesting that NHTSA investigate whether this defect is part of a wider safety issue affecting 2023 Chevrolet Silverado 1500 transmissions and determine if a safety recall is warranted.

I was towing my boat, attempting to get on a 4 lane highway via on ramp. Truck refused to shift and went into limp mode as I was attempting to merge. Vehicles behind me on the ramp and coming up behind had to slam on their brakes. Diagnosed as a bad valve body. The issue is very widespread across gm vehicles, gm has a national backorder on the valve body as there are a ton of vehicles waiting for them. Gm has not issued a recall at this time.

Was driving home and truck stuttered three times then went into limp mode, dropped truck off at dealership and was told it had a loose wire so they plugged it back in and charged me $200. Next day it happened again and brought it back when they told me my truck needed a replacement valve body. I've now been waiting over 2 months paying $858. 18 a month for a truck I cant drive.

While driving at ~30 mph the rear wheels locked up momentarily with no warning and without applying the breaks. The back of the vehicle fish-tailed while the tires slid. Following the incident the check engine light came on and the vehicle went into limp mode and would not go more than about 25 - 30 mph. I immediately took it to the Chevrolet dealer. The dealer indicated that the codes showed an issue with the transmission control module. It is currently at the dealer to be repaired. The vehicle has 51917 miles and is still under power train warranty. There was no warning or indication something was about to happen prior to the incident. The truck is a 2023 Silverado 1500 with the 2. 7 liter turbo engine with the gm 8 speed transmission.

This is the third time since the purchase date of July 2023, that my diesel 1500 silverado has gone into "reduced engine power" while driving. The first date was August 2024, while traveling down the interstate. The check engine light came on. My maximum speed was reduced to 50mph, and the transmission shifting was very jerky. This was extremely dangerous with the flow of traffic traveling 70+ mph. I returned to the dealer where the vehicle sat on the lot for approximately 60 days awaiting the part (valve body) from gm. Components were repaired through warranty. Fast forward to February 2025, "reduced engine power" notification came on again with the code p0747, p700. Returned to dealer, and after a week of sitting on the lot, the technician could not duplicate the code. I requested that a new fuel filter be replaced for piece of mind. Today, 3 mos. Later, as I was backing out of my driveway, my truck did not shift/engage into reverse. I was able to roll into the road & put it in drive, however it went into "reduced engine power. " the vehicle will have to be towed, at my expense, I'm sure, to further diagnose the cause. The truck does not move when shifted into reverse, and pressure is applied to the pedal. It is extremely concerning knowing a national recall on identical gm components has been reported, and yet I have had identical issues without resolution. Despite the known problems and safety risks, especially with a child in the vehicle during each failure, I’ve been left without consistent or timely support. I am requesting immediate assistance in diagnosing and repairing this vehicle, as well as a formal explanation of why this recurring issue has not triggered a broader response or replacement. At this point, I’m also considering pursuing further action through gm corporate or a consumer protection agency if a permanent resolution is not reached.

On the freeway transmission downshifted to first, loud bang and skidding to limp mode vehicles behind us skidded off highway and others changed lane causing chaos yelling screaming angry drivers, not a great situation, I had the recall done, it was just a software update that detects a problem and puts it into dangerous limp mode at high speed.

Valve body failure on transmission.

The symptoms since the beginning of 2024 have been that when braking between 7 and 10 mph, you feel a bump or a skid, and when you stop, the engine shakes for a moment as if it's going to shut off. This happens with the auto stop-start off. A sudden braking moment can affect the vehicle's performance, making it difficult to control and increasing the risk of accidents, especially when it comes to a pickup truck that may have a trailer with cargo or objects in the bed that can be thrown. The trailer can even leave the road, losing control of the car. In 2024, I took the truck to the place where I bought it, bomnin Chevrolet dadeland, for a checkup. I explained all the symptoms to my advisor, just as I do here. I had to take it to wait for a loaner. A few days later, I took it back, and they had it for almost a week. When I picked it up, my advisor told me everything was fine. When I left the dealership, I found the same symptoms, so I went back and told him the car was still doing the same thing, and he told me it was normal. After much insistence, he got in the car with me to show him the problem, and the car did it several times, but according to him, it was normal. Now, in 2025, a week ago I took it to miami lakes auto mall to get checked out with the same symptoms and explanation. I started investigating why that couldn't possibly be normal car operation. They found they had to replace the torque converter and valve body because they found an excessive amount of metal in the transmission. The valve body is on back order indefinitely at all dealerships, so I had to take the car in that condition. Before taking it, I spoke with the manager and gm to ask them to give me a car until they fixed mine because it wasn't right for me to drive the car like that. But they didn't offer me anything. I took it back to bomnin Chevrolet dadeland and they told me they were going to change the transmission and torque converter and conveniently they didn't have to change the valve.

While accelerating from a traffic signal the transmission shifted very hard and caused the vehicle to suddenly lunge forward.

2023 Silverado 1500 zr2 19000 miles,motor shut off going down the freeway pulling my sxs at 70 miles an hour no warning nothing alarm nothing. My wife and I were scared to death trying to get off the freeway pulling a trailer and not knowing if the truck would make it. People around us beeping there horns with flipping us off,no warning. 300$ to get my trailer toed back home. Dealership tells me they don't have a loner but would give me a voucher. I have been trying to trade out of the truck after hearing about the truck problems 6. 2 is a bad motor I new it was just a matter of time. Now I am stuck. The scariest part was the timing could not have been worse coming off the freeway. How do I know even when it is fixed it will not happen again. Then we could not get the truck in neutral to toe to dealership so they dragged the $80. 000 truck on to the toe truck nice.

I was in stop and go traffic, the truck engine turned off I could not get it to crank. I was stuck in the middle of a busy road for at least an hour until the tow truck driver got there. Since the truck has electric shifting for the transmission, I could not get the truck into neutral to at-least push it to a safe place. I was informed by the dealership that there is no neutral override unless the vehicle is running. The shifting and fuel system “fuel module” failure is a know problem from gm and need to be recalled. If this would have happened on the interstate I don’t think the outcome would be great. The truck is a little over 1 year old and has under 15,000 miles. Very dangerous situation.

At 19k miles the transmission had a shifting problem and went into limp mode forcing a deceleration while on a highway. Had to unhook the battery and hook it back up to clear the code to get to a safe point for towing. Had to do this 3 times. Once at the dealer they could not recreate the problem. One week later it went into limp mode again. Took it to the deal and was informed that the valve body in the transmission would need to be replace. There is a supply shortage on parts and I am now without a truck for who knows how long.

Valve body went bad. . . Like so many others. No eta on part from gm. Not a good situation from a business owner that needs a truck to conduct business.

At 383 miles the engine started a ticking noise. Around the same mileage the transmission would also start make hard down shifts, especially into 1st gear. At around 27000 miles transmission would also shutter at light loads and low speeds. Attempted to take it to dealer 2 different times, but they had no loaner cars and needed it for more than a day. At milage 28,251 I drove to the dealership an insisted that it needed to be fixed. They were able to provide loaner car at that time. Engine ticking noise was cylinder number 7 lifter stuck closed. Transmission was unable to be checked due to engine needing repair. The dealer replace all 8 lifters on drivers side of engine. Upon the fix they test drove for the transmission problem and noticed noise coming from the water pump. Replaced the water pump and was told transmission needed a new valve body. Those parts were on back order for over 3 months. They found a service bulletin to reprogram the transmission so they could release the truck to me instead of hold months for parts. After more than 30 days in shop picked up truck. After driving around for a few hours noticed engine noise again but different. Like a bearing? dealer had already closed so took it back the next day. Couple days later was informed that the head gasket was installed wrong? really. Went to the dealer's new car manager and asked to be traded out of it and into a new truck. Dealer offered me 10,000 below blue book for trade in! they didn't even want their own product back. Picked up truck couple days later and drove straight to Toyota and traded it in I needed a reliable truck. The dealer's service department was great with the problem. But it's the product that really [xxx] and had the potential to be very dangerous. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was on expressway with the cruise set on 72 miles an hour I heard a loud clunk the engine, of course shut off I go down to the gearshift in the console. It said neutral so close it over to the side of the road got stopped as soon as our momentum stopped and we are completely at a standstill the truck put itself in park. I then tried to restart it and it wouldn’t do anything. I contacted onstar state in my situation and after multiple conversations with them, I disconnected the phone call and contacted my own towing service because we were 51 miles from our home and they would not tell the people there unless I paid for over half of it. They would only tow it to the nearest dealer. We have been a free customer since 1997. We or a family owned electrical contacting business. My truck is my office. I’m in 90% of my day. I elected to take it to the dealer where we purchased it, and we purchased a good portion of our vehicles over the years and helps that it would be repaired in a timely manner.
