What 179 owners told NHTSA about the 2011 Chevrolet Silverado 2500

as mentioned by many customers the dash on the vehicles crack and GM refuses to pay for repairs. Now there is a Airbag recall that needs to be completed and I am told by dealer that the dash will crack more and get worse during the repair and they are not responsible for the damage. This is unacceptable and unsafe as it is costing me and consumers more money for a defective product.

With all the known issues involving the failing CP4 fuel pumps out in the field, why hasn't there been a nationwide recall on this issue? We're being proactive in getting our LML repaired to save our engine. We want our costs reimbursed. This isn't a "small" matter. It's freakin' huge.

The transmission control module (TCM) began acting erratic. At times the transmission will not shift but several times it has gone into park( with no warning) when slowing down causing the wheels to lock and the truck skids to a stop. I was nearly in 2 accidents when this happened. Both time I was hauling a load and caused the traffic behind me have to swerve to not run into me. In looking into the issue I found that in 2011 GM had put out a shop notice that they had a known problem with the TCM and they thought it might be caused by a non-OEM fan belt causing electrical discharge that might impact the TCM. A second shop notice from GM stated that the issue was due to heat and since they has mounted the unit on the fan shroud it should be moved. But none of the shops I went to knew about these shop notices from GM. Thousands of TCMS have failed but no recall. GM has now greatly reduced production of replacement modules and the cost of a new TCM has gone from $400 to $5000 ( Plus programing ) and a long wait time to get one. You can get one refurbished for $1200.

It is a transmission control module wear a lobster transmission into a Garin. Will not let you speed up or speed down and it is unsafe and GM IS making us pay for the bill. The contact stated transmission control module all across the country on back order, you cannot get a dealer to get you one within six months GM should have to do something about this.

The vehicle started to shift on its own mostly between the upper gears even though terrain or load had not changed. At slower speeds the vehicle started to automatically shift into park and lock up the wheels. This caused a very serious risk of injury to me and the people behind me when it would lock up. After stopping the vehicle sometimes does not move when in drive. There are no warning lights Took it to a shop and they checked it over. I was informed that there is a known issue with the electronic transmission control unit (TCM) for the Allison Transmission. The issue is with the location of the TCM. GM has developed a new unit to replace the original TCM that is engineered to no be affected by this. But due to the demand GM has a back order on the new TCM. The cost to get a TCM has risen from $800 dollars to $5000 dollars if you can find one.

GM is aware of a known failure in their Transmission Control Modules. My part number is 24256670. My truck has 87,000 miles on it and not drivable due to this failed electronic component. There are thousands of people just like me experiencing this issue. Check engine light illuminates once unit gets hot. Multiple codes will display at this time. This happened at a stop light, causing traffic jam and congestion, unnecessary safety infringement on all i affected.

My truck has been at a dealership since May 31st , 2022. It needs a TCM. While researching , plus calling aftermarket parts suppliers(Auto zone and others) , and also calling auto recycling/salvages yards , there are Zero TCM's available unless you get lucky at a auto salvage yard minutes after a wrecked truck shows up. There is a huge issue with the TCM's failing on these 10 year old trucks , and GM refuses to allow their supplier to make replacement TCM's. I have lost the use of my truck for almost 6 months at this point. I would also like to know how many other customers are waiting for a TCM.

Occasionally, a no start condition can be traced to fuse contacts losing conductivity which can be resolved by removing them reinstalling fuse. Has potential of causing electrical fire
