1999 Chevrolet Suburban: engine knocking or ticking

Filed Aug 14, 2001 · Seats · TX

Seat failure-the driver side seat support broke causing the seat to lurch forward and backward upon stopping and starting of the vehicle accompanied by a loud popping noise. Dealer is replacing supports on both the driver and passenger seat since the passenger seat was also loose or cracking. Engine-the original engine in the truck failed. The crankshaft rod bearings were badly worn. The trouble was detected by a slight knock in the lower part of the engine. The new engine started to produce a "tapping noise" upon cold start up. The dealer said this was a normal noise due to loose pistons (slap). The noise subsides after about 4 minutes of warm-up. If this is piston slap, the engine will wear faster causing premature failure. I called gm and they were not interested in the discussing or helping with latter problem.

The truck has had a severe vibration in the front end since it was delivered I returned the vehicle to the delivering dealer with 845 miles on it for service. The vehicle stayed at the dealership for 11 days the drive shaft was removed and sent to be trued it was then reinstalled. The original factory tires were removed and replaced the front end was aligned. This same procedure has been repeated a 2 other dealers trying to correct the problem. Late in 1999 the truck was at day's chevrolet and the service manager ben larue showed my husband a similar 1999 up on a lift that the torison bar support and assembly could be bent with a pair of vice grips the metal is inferior. The front end of the this vehicle has been braised at the torision bar assembly it has had the ends of the torison bars grounded down and returned to us as fixed. Chevorlet has just had their last repair attempt and they took the front end apart and packed with grease to correct the noise and vibration it did not work. We still here the noise in the front end it still vibrates at highway speeds and is very annoying. The transmission has slipped since the vehicle had about 8,000 miles on it every time we take it in we are told they cannot duplicate the problem. It still will slip at low speeds up a steep incline it will also roll when put in park. The brakes have always been an issue with this vehicle I reported this on the first time back for repair. The vehicle has leaked on the left side at the 2nd door and the rear doors. The vehicle has had a ticking vacuum noise since the day it was new the dealerships told us they know it is annoying but do not how to fix it. This vehicle is not safe it vibrates it will not stop and chevrolet will not do a thing about it we have been through bbb and currently pursuing lemon law.
