Buick LaCrosse multiple warning lights on dash

We recently traveled from TX to FL (summer vacation). Our first long trip with the car we purchased late Dec/12. Prior to vacation we brought the car in to be serviced. This was an opportunity for the dealer to check a couple of continuous problems. The Service Suspension warning as well as the check engine light have come on at least ten times since we purchased the car. In spite of many efforts by the dealer to resolve the problem they still come on.

During our travels we had an assortment of warnings (Service Suspension System, Check Engine, Service Parking Assist, Low Tire Pressure). All these lights coming on was somewhere between funny and well kind of sad since my wife likes the vehicle.

We are very unhappy with these lights and warnings coming on all (I do mean ALL) the time. It makes us doubt the quality of the vehicle, our safety in the vehicle, ... At this point neither of us is sure what to do with the vehicle.

Is anyone else seeing these problems? What have you done to resolve them? The dealer thinks they have found a misfiring piston problem that will resolve the check engine light but we have four warning lights coming on with little if any resolution to the problems.

  • Hi Laura,

    Lets see what happens after this visit to the dealer. If the light / lights come back on I will absolutely be in touch.

  • '05 Lacrosse: The "low washer fluid" alert is displaying. The fluid tank is full. The manual says to hit any of the DIC buttons to clear the alert. This works until the next time the car is started, then the same display. I'm thinking about disconnecting/reconnecting the battery to see if that resets it. Any suggestions? Thanks.

  • I drained the fluid reservoir using plastic tubing/hose. Kinda worked the end of the hose around both going in/out in the event "something" was hung-up in there. Also, with the reservoir full and hose at the bottom of the tank, blew bubbles trying to dislodge whatever. Apparently these hi-tech procedures fixed the problem; "low washer fluid" alert no longer displaying AND the washer works. crazy.
