Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #2

Mar 012011

Silverado LX 5.3L V8

  • Automatic transmission
  • 99,000 miles


This is mostly copied from another complaint to illustrate the same exact problem..."I Heard a knocking sound when started and stopped after a few minutes of warming up. ...I was driving and engine started to overheat stopped and checked coolant was low saw no leaks. I took to radiator shop replaced gaskets. about a week later was filling up with gas turned ignition on "CHECK ENGINE OIL LEVEL" warning came on checked with dipstick barely registered on dipstick add a quart took back to quick lube where oil was changed a month earlier they found no leaks...I started doing research online and found others having same problem". This problem is not uncommon, faulty, porous heads of type "Gaskel" I believe. Waiting for full quote, but labor alone estimated at $1650 (~ 2 days, really?!). Appears to be a know GM issue...sigh.

i still cant believe it that at 112000km the cylinder heads will crack. what kind of engine is GM building made out of plastic. i have been driving GM for over 30 years and i always believed in them but no more. i spent $50000.00 on this truck and took good care of it and look what i end up with. my next truck it will be a toyota. thank you
