I recieved a recall notice from Chevrolet stating they needed to install a software update to the truck which will warn if a potential rear wheel lock up is about to occur due to faulty transmission valve body- which was stated that they do not have a fix for. After software update was installed- I was driving about 35 mile per hour on the trip home, and the truck abruptly downshifted very hard, momentarily locking up rear wheels, and the check engine light came on, and the vehicle message came up stating the vehicle was placed in a reduced propulsion mode(limp mode). The next day it did it again on my short drive to work of 2 miles. I took into dealership and they informed me that the valve body had failed- as mentioned in the recall notice. It is now 1 month later and I still do not have my truck back, the part is back ordered, and they have no idea when it will be fixed. I am without my primary form of transportation.

Incident: March 6, 2025 · Filed: March 6, 2025

The sudden rear wheel lock up recall that GM has released for the 2020+ Silverado's with the 10-speed transmission does not go far enough. The recall simply reprograms the PCM to alert the driver 10,000 miles prior to the valve in the valve body failing, puts the vehicle into limp mode, and extended the warranty on the valve body to 15 years or 150,000 miles. GM states there is no fix available and this is not correct. NextGen Drivetrain has developed a fix for this per their website [XXX] ). On their site they also provide videos of trucks experiencing the lock up where it seems that the vehicle downshifts to 2-nd gear at high speeds and creates a violent jolt. This is extremely troubling to me as these vehicles are meant to tow, and I am very fearful that this issue will happen while towing a long trailer while my family and I are traveling and putting them in danger of an accident. It is very concerning to me that NHTSA would allow for this type of a "FIX". I am not sure if you have seen the videos of this issue happening, or know that a fix does seem to have been developed. I ask that you please reopen this investigation and revisit the way GM is handling this recall, and look into the fix that NextGen drivetrain has developed.

Received a code P10D9. Infotainment center says 157 miles until 65 mph max speed. Dealer has no idea what’s wrong

Incident: December 30, 2024 · Filed: January 19, 2025

During operation of the vehicle at approximately 45mph and sudden stopping/ breaking is required, truck fails to do so. It is a partial loss of brake pressure and a loud "whale cry" type sound that appears to be coming from under the hood. I have had it happen twice just recently; I have taken to dealer, and they cannot replicate the issue. I have caught the sound the second time on video. To summarize truck loses partial breaking power, pedal does not bottom out, but it feels like there is not as much pressure being applied to the breaks when needed. Once the sound stops all braking returns to normal.
