We have owned this car for about 3 years and it has been one problem after another and see same problems on line 1) Will start over heating sometimes at idle sometimes while driving (try being in DFW rush hour traffic and deal with that 2) Wife was driving one day and a bolt on right lower control arm broke sending her across 4 lanes of traffic including on coming. 3) All of a sudden when brake pedal was depressed started hearing vacuum leak under dash, brake pedal real hard, and couldn't hardly get car to stop, traction control light started flashing. Found bad brake booster and sensor located on it (both unavailable from manufacturer), also found on line that to get light to stop flashing you have to take to dealer and have reprogrammed (nobody else has the ability) 4) Have constantly had problem with check engine light staying on and running rough, no power, and having to replace ignition coils 5) While wife was driving with no advance notice of any kind heading home on farm market road with no shoulder to pull off on transmission went out completely and stopped pulling 6) Rear control arm bushings go from ok to extremely bad causing back end to drift from side to side going down the highway in a blink of an eye 7) Right front sway bar link keeps wearing control arm and snapping stud off 8) Sunroof drain hoses constantly failing and allowing water to get to electrical components The list goes on but all you have to do is a online search of the LS sport with the 3.9 v-8 and see all the problems. I was in automotive for over 16 years and every vehicle generally has its know couple problems but this is way beyond that. There hasn't been any accidents or injuries but real close to it.

While driving this car on a highway or street any time it encounters small bumps the wheel turns and there's a loud slamming sound from the front passenger and driver side of the car. It's worse going into turns speed does not matter you can go slow or fast and the loud slamming sound is there. It feels very unsafe and dangerous. But me being a senior citizen with a son who as a disability we cannot afford to get this fixed our selves. It started a while ago but was not that bad but it just progressed and got worse. We need this car for doctors appointments and food shopping. We cant travel far for fear of being in a crash or being stranded.
