2024 Chevrolet Silverado 2500: check engine light

Filed Oct 29, 2026 · Electrical · OH · crash

The backup camera system blackout for half a second and shows up in another position as if the vehicle moved sideways as backup straight. Completely throwing me off direction which make the entire experience full off uncertainty. This has happened since the day I purchased it in 2024 from McNeil chevrolet and they only wasted my time telling me that they reset the computer and SHOULD BE FIXED ( never fixed it !!) Constantly asked about a fix for backup camera when getting other services and recall work done but never fixed or even a apology. They just add on the bill that they washed my truck which never ever happened (lies). So I tried a different dealership (Ballas) and they did replace the 0w20 weight oil that wasn't supposed to be ran in my 6.6 gas motor that Swanton Ballas had put in it, trust the dealership professional they state in their ads now had the wrong oil in it for 1-2 thousand miles. So this dealership looked into the camera system and seen the issue but wouldn't verify it by a simple video or even just put it in writing (Protecting the manufacturer company from responsibility). I contacted GM and I was told that I can get it fixed when they have a fix and here's 30,000 GM points for the waiting. I have already waited nearly 3 years and still no fix. I paid $95,000 for a truck that should have been $70,000 because I originally purchased a 2024 diesel truck from Yark in [XXX] and on my way home with this brand new truck the engine light comes on. I called and the salesperson told me to bring it back right away, and when I got there I told him I don't want it being a problem right away after that he reinsured me diesel motors don't have any issues. He just said that my money was already in the bank. After months of a check engine light coming on constantly and having to go back to have the dealership turn it off GM agreed to build me another truck but I don't get any money back from the 10k motor. GM will not back their own work!!!!!!! Scamming INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR

First started around 4 to 6000 miles, felt a shuttering between 50 and 65 mph. Shattering lasted from 10 to maybe 30 seconds let off the fuel and reapplied still there on one or two occasions. RPMs were approximately 2000 RPM shattering stopped in our PMs went down to 1500. This is occurred many times taken to a dealership always get same result, no problem found. Problem always occurs just after a transmission shift which I can tell by RPM. When I apply gas shuttering sometimes increases not always. Also noticed that sometimes shifting on a flat surface 65 miles an hour engine will speed up to almost 2000 RPM and when it goes to shift back, I get a clunk or sometimes a shutter normal cruising is about 1500 RPM at 65 mile an hour. I didn’t notice towing an empty trailer about 2600 pounds shattering seemed worse. With no Trailer I sometimes get erratic shifting where RPM goes 1500 to 2000 to 2500 and then back down again then back up again then it can shift all the way back to 1500 RPM still maintaining 65 mph. Also another problem may be connected to transmission, but I have pulled out into traffic pushed on the pedal and it feels like the truck has no power push on the pedal a little bit more still no power and all of a sudden it’s like everything kicks in RPMs, increase rapidly and truck accelerates extremely fast, throwing things off the dash moving things on the floorboard. Sometimes I see that a downshift occurs and RPMs increase other times I see RPM staying right at the 2000 mark and it still occurs almost got rear ended a couple of times. Check engine light has been on one dealership said they pulled over 40 codes. Still they all claim can’t duplicate problem. Yes I agree it is random but with me watching telemeter and County shift points biggest problem area is fourth gear fifth gear and sixth gear.

In May 2026, my vehicle began exhibiting serious and dangerous problems. It would shake violently after starting and occasionally stop on its own while driving. On [XXX], my wife and I got into the vehicle and started driving from our home in West Virginia. While driving uphill at approximately 30 mph, the vehicle suddenly began shaking severely and then came to a complete stop. After a few moments, it restarted itself and accelerated to about 30–40 mph while continuing to shake violently. This happened several times during the trip. Fuel consumption also became extremely abnormal, dropping to approximately 6 miles per gallon. Because Team One Chevrolet in Oakland, Maryland, is the nearest dealer, we drove there for service. After several hours, the dealer returned the vehicle and informed us that they had replaced a sensor. However, after leaving the dealership, the Check Engine light came on again after only three engine starts. I immediately returned to the dealership, where the warning light was cleared. The following day, the Check Engine light returned. When I contacted the dealership, I was told to continue driving the vehicle with the warning light on for one to two weeks. After more than a week, I returned to the dealership, and the light was reset again. A few days later, the same problem reappeared. At that point, I was informed that, according to dealership procedures, replacement parts could not be ordered until the issue had been reported three times. After the third visit, the parts were finally ordered, and I was required to wait several more weeks for another service appointment. I also reported the issue directly to Chevrolet. Despite multiple visits, repeated failures, and a significant amount of time spent attempting repairs, my vehicle remains unrepaired. My factory warranty is approaching expiration, and no one has provided a clear answer regarding what will happen if the upcoming repair attempt fails to resolve the problem.

Transmission Control Valve failed causing my vehicle to drop from 70 miles per hour below 40 miles per hour rapidly on the highway/interstate which could have caused a fatal crash. Called OnStar and was told my code showing was P0747 meaning service now. I called dealerships to get an appt next morning and this happened in the evening and was told the soonest I could get in was a week away, most was longer than that. I did worked in and was told my TCV needed to be replaced. I was told this is a common problem with this truck but when I contacted GM they told me they could only do a 30% courtesy discount because my 2400 Chevy Silverado 2500HD already had 83,000 miles on it and is out of warranty. I have researched this and the federal safety agency already has a bulletin in place for this same issue but it didn’t include my VIN so they told me there was nothing more than can be done. This is a huge safety risk and concern. My daughter and wife could have been driving my truck and it could have caused a very bad wreck. My vehicle had no prior warning until this happened. My vehicle did say reduced engine performance and my check engine light came on during the event but nothing prior. Now my truck shifts hard and gets hot fast. We opted not to drive and took it to a local dealership for repair due to the risk of injury if we continued to drive it to us and others. We are not put out a vehicle and monthly payment as the part is on back order. GM pretty much is brushing us off and told us we can file a complaint with the federal safety agency if we feel like it’s something more that needs done. Bulletin number in place for this issue on other VINS is N242454441. I don’t want this to happen to others so I wanted to report it plus I feel like GM should have cover total cost especially with it being a known issue. Thanks

While driving the vehicle, the vehicle jolted and made a clunk noise. The check engine light came on accompanied by a message on the Dash stating "Reduce acceleration, Drive with Care". The vehicle went into "limp mode", and appeared to be engaged in a single gear. The vehicle was traveling at approximately 30 mph when the transmission malfunctioned. The vehicle was taken to my local Chevy dealer, where they scanned the vehicle and determined that the Valve Body was the issue, based on the scan result. The vehicle is a 2024 Chevy Silverado 2500HD (Gas). It has 29k miles on it. The vehicle was purchased as a "certified Pre-owned" (lease return). Within 20 miles of being driven from the dealer after purchase, I experienced a jolt & clunk. The failure occured 42 miles later.

While accelerating to merge onto the highway, the transmission attempted a shift twice and could not complete the shift. That process causes an aggressive deceleration with each shift attempt. It then slowed, turned on the check engine light and displayed "Reduced Power Mode" - i.e. went into limp mode. The dealer pulled code P0747. The repair is a full transmission rebuild. I did not experience wheel lock up like other people have, but this is the same problem that has been heavily documented.

When driving, between the speeds of 40-50mph, the wheels would lock up without warning. This happened 4 times during the month of January, sometimes in 4wd. This occurred at speed when the vehicle seemed to be upshifting. Control of the vehicle would be lost during the lockup as the wheels would stop rotation entirely and rather violently. Check engine light came on after the 4th incident, reducing power and a code of P0747 "Pressure Control Solenoid "A" Stuck On". The transmission valve body was repaired by the local Chevrolet dealership under powertrain warranty. This is a known issue on previous years of this truck with the same transmission but has not been expanded to cover this vehicle. Thankfully, I was able to maintain contorol and was not in traffic when this occurred. I notified the dealer that the vehicle was shifting very hard during the last visit but no codes or issues were found at that time indicating an issue.

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that while driving at various speeds, the vehicle entered LIMP Mode. During the failure, the transmission became stuck in 5th gear, and the vehicle operated at reduced speeds. The vehicle was turned off but failed to immediately restart. After approximately 15 minutes, the vehicle restarted, and the failure was self-corrected. The failures had occurred while hauling a heavy load and while not carrying a load. The message "Decreased Acceleration" was displayed, and the check engine warning light was illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The transmission fluid was flushed and refilled, but the failure persisted. The manufacturer was not yet notified of the failure. The failure mileage was 54,000.

The check engine light goes on continously and it goes to limp mode. The truck cannot be driven daily and most of the time is in the dealer fixing the updates or computer. It is not an equipment problem but a computer problem.

My truck had approximately 55,000 miles on it when the incident happened. I pulled out of a store and began going down the road and the rear wheels locked up slamming everything forward and the truck and leaving us almost rear ended. The truck was stuck in one gear after breaking the tires free with check engine lights flashing and the dash saying reduced power. It has since been at the dealership for 3 months waiting on a valve body with no end in sight. There is apparently a national back order on these faulty parts because of how common this high speed rear wheel lockup is so I am left without a vehicle or an end in sight.

While towing my travel trailer at 55 mph the truck rear tires locked up causing an alerting situation. The transmission automatically shifted out of tow/haul mode, the CEL illuminated and the following message appeared on the dash "reduced acceleration condition, drive with caution". This event happened a total of 3 times within a 20 mile distance. Because it was a short burst and I was traveling on a straight section of roadway, the risk of accident was moderate. This would have been a high risk of danger if I were on a curving downhill section of roadway. The situation was confirmed by my local dealer through a diagnostic check exhibiting a P0747 and P0700 error code. There were no CELs or other warnings prior to the lockup. The diagnosis was a problem with the transmission valve body. A new valve body was ordered and arrived 14 days later. After the new VB was installed the symptoms appear to be gone after driving about 50 miles.
