2015 Buick LaCrosse Complaint Log

I had first seen a check engine light for a month and it would come on and off and sometimes it would stay off for about a week before it comes back on and do the same thing. I had noticed some slippage within the transmission a week prior to this incident and was looking to take it in for an inspection but money is tight so I couldn’t afford to go in for an inspection, especially a repair. I was driving to work and the vehicle was doing its slippage and I go about a mile or two until I reach an intersection, I came to a red light and stopped, when it turned green, I started pressing on the gas but the car didn’t move, it only revved. I then proceeded to put it in park and turn it off then on, only for it to do the same thing. So from there I had it pushed off into a nearby parking spot and then towed to a wrenchrite where they had confirmed it had nothing to do with the transmission fluid or anything minor. I then had it taken to Emory Services and they had confirmed the transmission its self had been fried.

Transmission problem. Jerking when going into gear.

The part of the driver seat belt that goes under the seat and is attached by a metal cable. The cable totally ripped apart. The date is approximate because I did not notice it until it was almost completely broken off. . I had the seatbelt repaired at the dealer Mangino Buick in Ballston spa New York, at the sum of $300they said GM refused to cover it. I tried to explain that this is a Safety issue not a warranty item. This never happens.

Fuel line under hood was rubbing against a bracket and is leaking. All the hangers and clips are secured and no play in Fuel line.

My wife was driving and went to turn the vehicle and the steering locked up momentarily. She drove directly home a block away and pulled into the garage. When attempting to take the car for service it would not turn in either direction.

The truck pops open on its own when park and while driving.. Had to pull the fuse just to keep it from opening.

The failure mileage was approximately 69,100.

Power steering went out while driving roughy 45/50 mph. Unknown reason why it went out.

While driving at approximately 55 mph, my power steering went out (at first I thought I had blown a tire). It became almost impossible to perform any quick/reactionary steering changes. I put on my hazards and drove to the dealership and then for a second opinion with my local trusted mechanic. Both advised the electronic steering assembly went bad, that there is a new part #, indicative of a high failure rate; however, the part is not available in all of North America (they checked.) they called GM Buick and were advised an ETA on the backorder for the part is unknown. They filed for an emergency backorder request and are awaiting further information. Now, I have an undriveable vehicle, there are no loaner cars available, the cheapest rental car is a full car payment every three days, and no idea how long before the vehicle will be able to be repaired as it is too dangerous to drive in its current state. I think this needs to be investigated, as this issue sounds like it should be a recall before someone gets killed.
