First things first we all know the transmission in this thing sux!!! Had it looked at after being truckless for a month to find nothing wrong. After minor maintenance the transmission actually started engaging again. You have to wait a few minutes, but it will eventually engage. Before the breakdown was getting a 1-2 hard upshift dealer said nothing wrong. Were they ever wrong. Still get the hard 1-2 upshift.
Getting a gurgling noise near heater core area. There is a law suit out on this one. Not sure progress. The suit states that GM began using Dex-Cool engine coolant in 1996, claiming that it would protect engines for up to five years or 150,000 miles. The suit alleges that the coolant did not produce the promised claims, and therefore costly repairs were needed because of damage caused by Dex-Cool.
Back window rattles and sometimes will open automatically while driving down the road. Not a big deal in the summer, but the winter leaves you a bit on the chilly side.
Passenger side seat control knobs have broken off.
Fuel Gauge has completely quit working.
Have to reset trip meter at each fill up.
Middle spark plug on driver side pain in the rear to change. But can be done. Struggled the first time.
Getting a clunking noise while turning left with a slight acceleration. Probably torsion bar mount or lower ball joint. Don't really care at this point!! Just trying to make it another year if at all possible to trade this bad boy in!!
