| At 12k miles the oil pressure light came on and continued to go on and off dependent of the rpm. the dealer diagnosed the vehicle with a cam shaft failure and due to that failure other subsequent damage occurred to the engine and it would need to be replaced. in addition, my steering shaft was also worn at 12k miles and needed to be replaced. and furthermore, i have had chronic issues with my gauge lights dimming and undimming intermittently. the dealer could not duplicate the failure and returned the car unfixed. very unhappy with my purchase of a brand new car and will not buy gm every again. *tr | |||

| I bought a buick lacrosse vin #2g4wc582461171671 on march 30, 2006. i picked up the car on march 31, 2006, and had a problem with a low oil pressure light that day. i was sick after picking up the car but attempted to use onstar diagnostic which they were unable to pinpoint the problem and i e-mailed the dealer concerning the problem. upon my recovery, i returned the car to the dealer for service on april 7, 2006. on april 10, 2006, the service department contacted and informed me that my car needs a repair to the camshaft assembly. this defect existed the day i picked up the car, it had 87 miles on it when i picked it up, and since the car was inspected the morning i picked it up, the dealer allowed a defective product to be sold and delivered. upon contacting buick to making buick is aware that this had happened and seeking resolution the dealer put a new engine in the car. it is not appropriate for the dealer or buick to sell a defective car and believe that putting a new engine in the car resolves the problem. i have complaint to buick and the dealer about this numerous time but i get stone walled, they completely ignore the problem existing prior to me buying and taking delivery of the car. i have asked for a replacement vehicle, partial, or total refund and i'm ignored. all buick does is offer oil changes and an extended warranty, which i find useless. especially when the onstar module failed, april 22, 2006, and had to be replaced. *jb | |||

| The low oil pressure alarm rang after only 1542 miles dealer made appt for 2/21 - wasn't worried probably only a false alarm. the alarm rang again at 1550 miles. i made the dealer take the car back to dealer. gm had to replace engine due to metal in oil pan. i've only made one payment and don't feel the car is worth a new car price. *jb | |||
