2024 CHEVROLET SILVERADO 1500 Complaints

Blown transmission valve body at 8000 total miles. Truck went into limp mode and will not reverse. Can not be safely driven. Has been sitting at dealership for 2 months now waiting for parts from GM. National backorder no ETA.

I purchased my vehicle in July 2024 brand new. I started to experience an engine shudder at about 4500 miles with the truck coasting or on the accelerator around 1500 RPMs. It first began at lower speeds around 40 mph, but now I feel it at high speeds as well. I brought my truck back to the dealership three or four times and they told me that the shudder was due to the active fuel management system in my 2.7L Turbomax engine. A different dealer said that it felt like a torque converter. There are no lights on the dashboard. The dealership I bought it from failed to try and flush the transmission fluid, only documenting that they did not feel the shudder on the receipt they gave me. However, during the test drive, they told me that they can clearly feel it. They failed to give me an explanation why there was no shudder for the first 4500 miles, and that it just started. They also stated that they had not heard of this problem yet, but said that it felt completely normal, which does not make much sense.

The automatic power running board of my vehicle has been coming loose. I took the vehicle to my dealership to get serviced. They said they tightened the bolts, and that the board is still loose. They also say there is nothing else they can do to fix the issue. This seems like a significant risk, as this component of the body of my car is at risk of coming apart further due to rattling while driving. I would like your help figuring out a safe solution.

I purchased my vehicle from Mak Haik Chevrolet 11711 Katy Fwy. Houston, TX 77079 on [XXX]. Approximately 4 months my Check Engine Light came on and I brought my Truck to Mak Haik Chevrolet to have it checked out. The Service Department could not figure out why the Check Engine Light had came on. They did complete the Recall N242435631 regarding a need to update the radio and serial communication firmware on my truck. On Saturday November 9th 2024, I brought my truck into Mak Haik Chevrolet for the 2nd oil change at approximately 10,000 miles, and the technician could not get the truck to go into reverse. I was given a loaner vehicle and told that they would contact me about the issue once their transmission technician could look my truck on Monday. I was contacted on Monday November 11th2024, and told that the Valve Body in the transmission was defective. Jim Cox, Service Advisor with Mak Haik Chevrolet, explained that he could not find the part, as this is a big issue with Chevrolet across the Country, and he would let me know when he has access to the part. I asked about replacing the transmission instead, and Jim explained that he could not get those in either? Mak Haik Chevrolet has had my truck since November 9th, 2024.

THE TRUCK FAILED GO SHIFT INTO REVERSE. HAD TO PUSH THE VEHICLE OUT OF THE PARKING SPACE. WHEN I TRIED TO GO FORWARD THE VEHICLE SHUTTERED AND THEN SHIFTED INTO LIMP MODE. DEALERSHIP HAS HAD THE TRUCK FOR OVER 8 WEEKS NOW AND I AM TOLD THERE IS A NATIONAL BACK-ORDER ON THE NEW VALVE BODY BECAUSE OF THE NUMBER OF TRUCKS REQUIRING REPLACEMENTS.

my vehicle suddenly experienced decreased acceleration on the highway. A warning message appeared on the dashboard indicating reduced acceleration. When placing the vehicle in Reverse, the vehicle was not able to move in reverse. The dealership diagnosed it as a valve body needing replaced.

Every time I tow my travel trailer within 150 miles or so I will get a message that the Diesel Exhaust fluid (DEF)is low and needs to be filled soon. Within 50 miles of that happening I will get the message that the DEF is low and will be speed limited in 500 miles. When I stop and fill the DEF fluid it only takes about 2.5 gallons which isn't even halfway empty. When the Speed Limited to 65 in xxx miles warning comes on you are unable to view any other safety related information such as tire pressure or temperatures. I took my truck to Classic Chevrolet in Grapevine, TX. in September and they kept a 6 month old truck for 23 days. They said there is an issue with the DEF software algorithm while towing and they don't have a fix. They have a technical service bulletin that tells them to instruct customers not to add DEF until they get the Speed Limited in xxx miles . In other words don't fill it up when it says it's empty. The DEF system is a government requirement and the manufacturer should be required to ensure that their system is accurate and working under all driving conditions.

Vehicle would not go in reverse or shift out of First gear Diagnosed as needing a transmission valve body replacement

Vehicle cut off while driving down the highway and wouldn’t restart. Had to be towed to dealer with a faulty fuel pump control module

Only 6k miles. Couldn’t go in reverse or get out of 1st gear. Brought to dealer, they said it needs a new valve body gor the transmission and there are so many trucks with this issue the part is on b/o for 2 weeks-3 months! In the meantime I have not truck.
