2006 Chevrolet Silverado Powertrain & Transmission Problems

I was driving down the highway at 65 mph and went to slow down and I had no brakes. Resulting in me having to go into the ditch to avoid a collision. After I was able to get the truck to slow down and to a stop I inspected my braking system to find all of my brake lines were rusted out and I had ruptured my brake lines. Since the incident I have had to replace all my brake lines and both of my brake cylinders on the rear of my truck. Now I have minimal brakes after bleeding them and they are slowly coming back. The truck has almost 400,000 miles on the chassis but a new motor. During this event I was getting a grinding coming from the rear differential, after inspection, I found that my gov lock was bad and needed new spider gears which I have since replaced the rear differential with a posi differential and have had minimal problems since.

On [XXX], at or around midnight, I was traveling [XXX] at approximately 60 mph. The traffic was very light, with few vehicles on the road. It was raining, and I was in the number 1 lane. Two additional lanes were to my left, reserved for toll road traffic. I did not see any other vehicles on [XXX], nor did I see any vehicles to my left in the toll lanes. There was a physical separation between [XXX] and the toll road, consisting of 36-inch plastic candlestick dividers with approximately 10-foot separations. As I was traveling, I suddenly felt a lurch, and the right rear of my 2006 Chevrolet Silverado (Vin# [XXX] ) dropped. My pickup truck immediately began to spin to my left, forcing me into the toll lanes and into the concrete center divider. When my vehicle came to rest, I was facing eastbound in the westbound lanes of the toll road. My lights were no longer except a single amber light flashing, which gave limited warning to approaching vehicles. The California Highway Patrol arrived (unknown why no traffic collision report was taken), my vehicle was removed from the roadway, the right rear wheel and tire had separated from the vehicle and rolled to the right shoulder of [XXX] 150 yards from where my pickup came to rest. The vehicle was towed to the tow yard, where a vehicle inspection was conducted on March 19, 2025. The right rear wheel and tire for some reason were not recovered from the collision scene. The inspection revealed the cause of the collision was a broken/severed axle, not related to driver error. Photographs of the broken axle were taken and are available for review. The axle clearly had a manufacturing defect, poor casting or forging. The defect appeared to be an ongoing problem and separated from the vehicle at the time of the collision for no apparent reason. Depending on the time of day, traffic conditions, and the number of passengers, the collision had the potential to be much worse. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The auxiliary transmission fuel pump system is prone to failure. This makes it so the start/stop feature will not work, as the vehicle will stall when stopped (causing an unsafe situation), and it cannot pass state inspection. The part is entirely unavailable from Chevy, and results in the vehicle being scrapped. There is no way to permanently bypass this system.

TRUCK DRIVING TRANSFER CASE GO IN NEUTRAL, THEN NEED TO PARK AND PUT THE TRANSMISSION IN PARK AND IN NEUTRAL, THEN PUSH THE 4X4 BOTTOM,THEN CHANGE TO 2WLD. MAKES A LOT NOISE.UNSAFE TO DRIVE.HAPPEN IN THE HIGHWAY.

ANYTIME A TRAILER IS FIRST ATTACHED, THE TRUCK WILL RANDOMLY GO INTO REDUCED POWER MODE WHILE DRIVING. THIS IS VERY UNSAFE AS THE TRUCK CAN TO THIS AT HIGHWAY SPEED IN TRAFFIC. IT WILL DO THIS A FEW TIMES UNTIL THE PCM "LEARNS" THERE IS A TRAILER ATTACHED. GM IS AWARE OF THE ISSUE AND ISSUED SERVICE BULLETIN 06-06-04-042B TO ADDRESS THE ISSUE BY REPROGRAMMING THE PCM. BECAUSE OF THE SAFETY CONCERNS, THIS SHOULD BE ADDRESSED AS A RECALL. HOWEVER,I HAD TO TAKE THE TRUCK INTO THE DEALER FOR THE UPDATE AND WAS EXPECTED TO PAY FOR THEM FIXING A KNOWN SOFTWARE ISSUE. INSTEAD OF DOING THE UPDATE AT NO CHARGE, THEY MANAGED TO DAMAGE THE PCM WHILE PERFORMING THE UPDATE. THE PCM IS NO LONGER SERVICEABLE AND THE DEALER IS WANTING TO CHARGE ME FOR A REPLACEMENT EVEN THOUGH IT WAS DAMAGED DURING A CALLED FOR SERVICE BULLETIN UPDATE. THE VEHICLE WAS NOT ORIGINALLY EQUIPPED WITH A TRAILER HITCH SO THE PROBLEM DIDN'T ARISE UNTIL THE HITCH WAS INSTALLED AND A TRAILER WAS ATTACHED.
