Silverado 3500 4WD 8-cyl

  • 123,000 miles


Problem with transmission cooler lines for the allison transmission. 123,000km's on my 3500 and the transmission lines have been replaced 3 times. 2 times were on warranty and the 3rd I had to pay for myself. I have extended warranty but is not covered, bunch of bs. Cost me 850 dollars to fix. Should be a recall on them, even the dealer ship says they have lots of problem with the lines. When ever it turns cold they start to leak and have to be changed.

2007 Chevrolet Silverado pickup truck. Consumer would like GM to buy back truck because of design flaws and suspected lemon the consumer stated onstar activated and stated the vehicle had been in an accident. The consumer called onstar to tell them that the vehicle had not been in an accident. The operator asked the consumer were there any lights on the dash. The consumer stated the air bag light was on. The operator attempted to instruct the consumer on how to reset the light, and stated if it didn't clear within two days to call back. When the consumer put the gear into drive and started to go forward, there was a tremendous explosion, dust filled the truck and onstar came on saying the vehicle had been in an accident. They vehicle was towed to the dealership. A week later, the consumer received a call from the dealership stating the explosion was caused by a poor design in the galleys in the floor, they went from the center of the truck to the drivers side door under a rubber mate. One of the galleys went through a rubber grommet which allowed water to leak into a compartment storing very high pressure compact cylinders for the air bag and seat belts. The water caused corrosion on the high pressure cylinders and caused the explosion. Also, the tailgate latch would not latch properly. The dealer found the pivots had seized. On cold starts, the transmission would hesitate and then a loud bang was heard. The dealer found a valve body bolt broken.

The contact owns a 2007 Chevrolet Silverado. The contact heard a noise coming from the automatic transmission and the vehicle was hesitant to shift into gear. The dealer repaired the vehicle under warranty. The failure recurred and the vehicle was taken back to the dealer. They stated that there was an issue with the vehicle and notified the manufacturer. The manufacturer advised the dealer not to make any further repairs until the transmission actually failed. The dealer obeyed the manufacturer. The VIN was unknown. The failure and current mileages were less than 20,000.

Hesitation on acceleration. While merging onto an interstate highway pressed the accelerator to rapidly increase speed but the vehicle hesitated causing me to have to continue down the shoulder and actually stop to avoid a stalled vehicle on the shoulder. I have taken my vehicle to two different dealers to investigate the hesitation on acceleration both have stated that this is normal operation for the 2007 Chevrolet Silverado. Although I didn't have an accident with this particular incident I have noticed this hesitation during normal day to day driving. This is a safety issue.
