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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Buick Lacrosse Hybrid verdict →
