The only thing I've had go wrong with this Saturn is the right rear taillight. It works fine until you turn on the headlights. Once the headlights are on, the taillight works until you step on the brakes. Then the left and center brake lights come on, but the right taillight goes out. This only happens with the headlights on. Saturn is aware of the problem and supposedly issued a recall, but I was never notified and it has not been replaced through Saturn. I replaced it myself once, but the new taillight did the same thing, so I've just left it alone.
I bought this car with 50,000 miles on it, and in the first year put an additional 47,000. It has never once gave me problems. It starts right up, runs strong, and all I do is basic maintenance to it.
It still gets great gas mileage (32 mpg on the highway) even with over 130,000 miles now on the engine, and the tires and upkeep are inexpensive.
This really is a nice little car. Not a lot of space, but enough for 4 people for short to medium distance trips, and for my job that requires me to drive a lot it's been perfect.
Glad you've enjoyed your LS. You're right about the taillight recall. You should be able to schedule an appt with the dealer to fix the car even though you didn't buy it new. They will probably need the car's VIN number. There is an updated connector for the light that will solve the problem.
