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.

Silverado LT4 5.3L

  • Automatic transmission
  • 30,251 miles

Engine knocked the very next time I started it after picking it up from the dealer. Took it back to dealer that it was purchased from as they had a better loaner vehicle policy and I would be needing a vehicle that weekend. Dropped it off Thursday night, Friday morning was called and told they heard nothing out of the ordinary. Asked that the vehicle be driven home by someone and checked several times. I was beginning to feel like no one believed me when I went in complaining of ghost noises coming from the engine. It seemed I was the only one who ever heard anything. Dealer agreed to keep trying.

Was called 5 hours later and told they did in fact hear it, and that is was significant and would look at it first thing Monday morning. WOOO HOOO!! I bit my tongue and waited for them to call me. I finally got the call on Wedsday, Oil and coolant was found in a blind (dry) head bolt hole and cylinder head or block was cracked and I was getting another new engine. This makes 3 engines in 30k miles, the second engine only made it 7k miles. I wish I could explain how I ended up with two (so far) bad engines. I do drive the truck hard at all. I really hope I got a good engine this time. Factory warranty is set to run out in 5k miles or 4 months.

Love the 4 wheel steer, had it still been an option I would have replaced this truck a long time ago. At around 12k miles on cold starts I would on occasion see a cloud of steam blast from the tail pipe. Once in 20 starts or so, passed it off as cold weather at first. At about 18k miles I had no heat in the cab, water pump was replaced. I then began getting a intermittent knocking noise on startup with the steam issue still there. One cloud almost obscured an entire parking lot. Dealer could not duplicate the problem though. Finally it happened. One morning after completing a long drive (100ish miles round trip)the day before the engine would not crank on the first try. Then engine acted like the battery was very low and only enough to move the crank a tiny bit. Tried it again and the engine rolled ever so slowly. One more try and it fired up rattling and clattering like an old diesel on a cold morning. I shut it off and called dealer to see about getting it towed in. I was asked to try it again and service writer heard the engine over the phone and arranged a tow. Cause was a blown head gasket that hydraulic'd the engine, was told I had damaged just about everything inside the engine. It was replaced. Mileage at the time was 23K and change. I noticed a couple clouds of smoke come from the tailpipe on startup with the new engine, nothing as bad as before. This seemed to be oil smoke as it hung in my garage for some time. Dealer could not duplicate the problem again. I then started getting that cold start knock occasionally on startup again. Couple trips in to dealer could not duplicate, finally was able to duplicate and a misfire code and noise was traced to #1 cylinder. All right bank lifters were replaced. About 7k miles on new engine at this time. noise continued and could not be duplicated on several trips to dealer. Finally was duplicated after I asked that the truck be taken home or driven around for several starts instead of me returning to pick it up again. Cause?? 7 thousand miles on new engine and I get a cracked block or head, not sure exactly, but oil and coolant were found in a blind (dry) cylinder head bolt hole in the block. I now have my third engine in my truck in a span of 7 thousand miles. Odometer reads 30500 miles.
