The thermostat housing blew at 37k and overheated the engine; the head had to be resurfaced and head gasket replaced. GM would not warranty it, only being 1k out of warranty and the housing that blew was plastic. A new revised metal unit was installed.
The timing belt broke at 47k and bent 10 out of 16 valves, which required the head to be removed again and sent for a valve job.
The timing belt broke again at 99k and put a hole in one of the pistons, which required replacing the engine with a used unit; this cost 2 grand.
At 135k the driver's side axle snapped going into the splined hub, which required replacing the axle and wheel bearing. The shop said the wheel bearing was bad and caused the axle to fail; this repair was 350.00.
At 143k the blower motor stopped working and that unit under the dash needed to be replaced. 123.00 to repair.
At 155k the idler pulley broke apart on the timing drive system, which bent all 16 valves in the cylinder head. This engine has a severely poor design and a lot of costly belt failures; GM should recall this engine, the head needed to be rebuilt on the replacement engine; 1,200 to repair.
At 171k the A/C compressor failed internally, sending metal through the entire A/C system. The garage wanted 800 to fix; I opted to leave the car without air conditioning and live without it.
At 187k the serpentine belt tensioner grenaded under the hood, causing the car to be stranded in the middle of nowhere. This required the tensioner and belt to be replaced; this was 250.00 to repair.
At 198k, all the belts including the timing belt flew off the engine going down the road, because the crank pulley fell off the engine. I was told the bolt wasn’t tightened properly. At this point I donated the car to a local vo-tech for automotive teaching as I was not going to rebuild the engine again, because valves were bent again. The garage wanted 3 grand to fix, I got rid of it.
