The line running from the transmission to the radiator is extremely prone to leaking due to a weak/improper crimp in the hose. As time goes on transmission fluid is depleted and could lead to transmission failure. The leak is widespread across most allison transmissions due to a faulty hose crimp and leaks through the crimp in the hose.

Silverado 2500 8-cyl

  • 26,000 miles
I purchased 2006 Silverado new and after the 1st year noticed rusting. Just before it came off warranty (2009) the coolant line from the radiator and the brake rotors (front and rear) had rusted through. Have since replaced the rotors again and now my brake line burst open as I was driving home. Entire undercarriage is rusted (frame is peeling up in layers), there is rust coming through the bumpers, on the wheels, in the bed, inside the driver's door - basically everywhere I look (I filed a complaint with Chevrolet in 2010 about the excessive rusting and was told, after inspection by local dealer, that there was "no abnormal rusting found"). I baby this truck (it only has 26,000 miles and is not driven on the roads when they are salted) and keep it very clean. I am afraid for my safety as I do not know what is going to fail next. Today I spoke with Chevrolet again about the brake lines, again inspected at the local dealer, and was told that it was "normal wear and tear" and caused by environmental conditions. In addition, I was told that the rotors and calipers are rusted through and must be replaced. How is it possible to conclude that the corrosion is due solely to environmental factors and not at all due to material choice and lack of appropriate coating? I am only asking that they cover the replacement of the brake lines and they do not feel obligated to do so. They do not believe it is poor design or subpar materials. (neither of my other two vehicles, 1993 Toyota pickup and 2004 Volvo, show rusting of the undercarriage to the same degree as the Silverado and the brake lines of both other vehicles are completely intact. All three vehicles have been subjected to the same environmental conditions.)

Bolt head is snapped off on the left exhaust manifold on the rear most bolt. I know of many others who have this same problem and I believe that their should be a recall on the defective bolts used in these vehicles.

Silverado 2500 8-cyl

  • 59,800 miles
I bought a 2006 Chevrolet Silverado 1500 crew cab used from bill byrd Kia in panama city Florida on 03/02/2009 and was told the vehicle would be covered under any remaining factory warranty, was led to believe it was a 5 year/100,000 drive train warranty. Unfortunately, .I did not do my homework on that statement. The truck had 36,581 miles at time of purchase. I have driven the truck for personal use only and took very good care and had regular oil changes performed. I am now facing a motor rebuild. The engine started making some knocking/crunching sounds from the low end and I'm told the camshaft, bearings, oil pump, seals, gaskets, etc have to be replaced at an estimated cost of $3,500. I have called the Chevrolet consumer number I found for their Corp office in detroit and am told by Chevrolet that this particular truck only had a 3 yr/36,000 mile I am left paying these repairs out of pocket on a truck less than 5 years old with less than 60,000 miles. I certainly feel ripped off after financing the truck for a period of 5 years. I have no choice except to pay for the repairs since it would have no trade in value in the condition it is in.

I own a 2006 Chevrolet Silverado with the 5.3 engine. I purchased my truck brand new and now have approximately 115,000 miles on it. Recently, I noticed a knocking sound coming from the engine and brought it to a GM dealership thinking it was a pulley or other minor repair. Instead, I was informed it was a bad cam rocker arm roller bearing. They proceeded to repair the issue and my total bill came to $3,242.84. I did some research on my own and found that GM has been aware that this part is defective on 2005 through 2007 5.3 engines, however, this part has never been recalled. With the amount of miles I have on my truck (over 100,000), it is no longer under warranty. In my research, I learned that this part is either an engineering defect or a supplied part that GM did not adequately contain before shipping the bad product to their customers. After numerous conversations with GM, they informed me that their engines basically do not last over 115,000. I have owned Chevrolet for over 36 years and have not come across any engine issues which is why I continued to buy them. Even after confronting GM with my findings, they are not willing to reimburse me nor are they willing to recall the defective part.

2006 Chevrolet 2500 pick-up w/8.1 motor. First there was faulty hoses causing low oil warning to come on. Now engine is low on oil with 1800 miles since last oil change. Had to put in 1 1/4 quart of oil. After engine break in. I switched to mobile 1 5W30 synethic. A recommended oil to use by Chevrolet. Dealers service dept. Says its suppose to use a quart to 2000miles. I don't believe that with the modern technology of engines. Maybe years ago but not now. If that's the case then Chevrolet should have said this engine uses oil. I guarantee you not many would have been sold.
