Engine complaints
2001 Pontiac montana, 48k miles. Leaks water on the drivers side area, drivers side electric window does not roll up without help, electric door locks do not work on passenger side, overheats, I'm told it was the head gasket or intake gasket which I am also told is very common for these cars around 50k miles.
Excessive valve clatter and consumption of fuel. *Ak
NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK
There is a knocking noise in the engine. Contacted dealer. Had engine repaired , problem reoccurred. *Ak
Battery amp gauge fluxuates random, maxing amp (18) then dropping dramatically dow as low as (8). Lights (headlights, brake lights, dash) brighten and dims at random including high beams. Car dies, steering becomes difficult at random when turning sharply to left or right.
Excessive oil consumption - approximately 1quart of oil is consumed every 1000 miles. Electrical - during acceleration the left front headlight shorts out. This has escalated to not turning on after the car is warm and driven, stopped and turned off, then turned on again. Currently, not turning on at all. If I tap on the light, it flickers. *Ak
