purchased car used at 158,000 have put 42,000 on it to date.my 1st issue was that the car was overheating at red lights in stop and go traffic,thus the cooling fans were not functioning.shop told me it was the cooling sensor,replaced and no change,shop then said cooling system needed flushed,guess what no change,then said it had to be fan relays,replaced all three, no change,shop said only 1 more option it could be,replace the bcm(body control module) $200.00 for unit,$100.00 to program. fans know work but will not go off,on all the time,even when you turn car off.did some internet searching and found someone with same issues,told me to change thermostat and all my cooling problems will go away,replaced it and guess what,fixed everything!next issue,car is losing power badly,shop says tune up,did this no change.shop says replace coil packs.did this no change,checked internet found these cars have catalitic converter issues,replaced and car now has more power than when i got it!3rd issue car's traction control lights come on when it rains and after i wash it,has progressed to on all the time now.checked internet found wheel speed sensors wire harness's are faulty.4th service tech found bad oil leak on back of motor,losing 2 qts per 3,000 miles.some kind of o-ring gasket on a cap on engine.5 clunking noise in steering,faulty shaft.
