2001 Chevrolet Silverado 1500: engine knocking or ticking

Filed Dec 10, 2016 · Engine · 106,500 miles · CA

I am the original owner of this very well maintained silverado. At just 100000 miles I noticed multiple exhaust manifold bolts broken, I had noticed a ticking sound for at least 10000 miles but could not locate the sound, as it turns out it was the broken exhaust bolts. These bolts break off at varying lengths including below flush which is extremely costly to have replaced. After a brief internet search I have realized this is a major issue with a majority of these vehicles. This is definitely an epa concern being the raw gasses are flowing out of the vehicle bypassing the catalytic converter and by not allowing these vehicles to pass regulatory smog certifications. This defect could also be considered a safety concern with the potential for the exhaust gasses to get into the passenger compartment. I truly hope that you can investigate these defective bolts and at the very least get chevrolet to acknowledge the issue and help with a portion of the cost to repair.

The steering shaft mid-joint is loose and is making a knocking sound, the fuel gauge is moving from full to empty while traveling down the highway, the power windows are losing power, when you power up the windows the headlights dim and the windows go up so slow

Parking brake hasn't worked since around 20000 miles, brake will depress, but won't keep truck from rolling. Loud piston slap, knocking from engine mostly when engine is cold, goes away after warmed up. This is a z71 and the 4 wheel drive buttons do not work all the time when trying to put into 4 wheel drive. Power mirrors don't work a lot of the time. At least one of the front running lights stay burned out most of the time. Truck is out of warranty now but these problems have existed for a long time. A lot of other trucks of this same model have all the same problems. Gm should address these problems and make them right at no cost to the consumer.

Nothing but problems with truck. First was the slip yoke in the drive shaft, felt like tranny was slipping from take off at start position. Replaced under warranty.*ak anti-lock brakes would come on with every stop. Usually at very slow speeds, causing truck to exceed 5-10 ft further than it should have. Had front wheel bearing replaced, fixed for some time doing it again. Also in the mean time, had to have all brakes and rotors replaced. Brake system is awful. This could cause accidents. Also, has cold engine knock, very loud knock, not a normal knock. Something isnt right with this. Done this since a little over 20,000 miles, worse when temperatures outside are low. Had to have 4x4 switch on dash replaced. Kept getting service 4wd unit. Out of warranty at this time. I know of at least 4 other with all same problems. Still nothing done with gm, something should be done. Especially with the brake system. Safety hazard.

Piston slap, this is a low end knock that mostly occurs during cold start up and goes away within the fist couple of minutes. This is a continuing problem. The tick / knock that is not normal.
