Same complaint another owner of a 2008 or 2009 Lacrosse Buick about a Check Engine light then a T/C light coming on at the same time? The engine is a 2.8L V6 with an automatic transmission. Has 46,800 miles as of this writing. Due to the July 4, 2016 holiday and being about 600 miles from home, it is a bit difficult to take it in to an authorized Buick dealer as per our warranty requirements..

The T/C light went off after shutting engine off and restarting but the Check Engine light remains on? This Check Engine light also occurred about a month ago. Took car into an "authorized" Buick dealer (as per our warranty requirements) to have this item checked. Nothing was found at that time...until now. Plan on driving car home tomorrow with hopes the engine doesn't shut down..don't plan on staying at this location (Brigham City, Utah) until Tuesday to have a local Buick dealer check out problem....which I hope this car doesn't break down as we continue on to our final destination in Arizona. Have driven this car with no Check Engine issues until today.

Also, have an Air Bag problem on the passenger side of this car. Stays on for 2 - 3 minutes (with passenger in seat) then goes off rest of the time...so, too bad for the passenger if the airbag doesn't go off if there is an accident. What great modern scientific technology we have...not only for this vehicle but for thousands of other vehicles in the U.S. that have this same issues where several people have already died or have severe injury if and when the bag is activated(?). I plan to take this in to the dealer to have this corrected...should be a big safety issue and the owner should not be responsible to pay for this repair.

Other than these issues, the vehicle runs ok...until today. Stay tuned for followup to these very important issues with this 2008 Buick Lacrosse.

Check engine light came on, car slowed down, got message to service traction system. Go to where I was going and shut the car off, after a while light went off and car operated OK. Second time it happened I was doing 65 mph on parkway and all of a sudden car slowed down, got the check engine light again, service traction system, after a while it went away and I was OK.

Once or twice over past 2 yrs it would happen but always went away so I assumed it was not important but for the past month it has been happening more often. Car is in a repair shop and cannot get the replacement part, must be a big demand for it.

Evidently this is something GM does not want to acknowledge. That is it for me, will never buy another GM car again. Only 47,800 miles on it and having this problem.
