The rear suspension has always been an issue. While driving the wheel will scrape against the wheel well. You can't fit more the two people in the back seat due to this issue. The two front exterior headlights don't provide adequate lighting to even see the car in front of you. Its extremely low/dense lighting even after changing out the bulbs. The electrical ignition switch to start the car has always been a problem. I have to turn the key, wait, turn it again, wait for the dashboard lights to come on, then finally the car will start. The power train gear control is another waiting game. To put the car in drive, I first have to slowly shift though each gear before finally putting into drive. Once I do put it into drive the car will suddenly jolt forward before I'm able to start driving the car. I recently had the transmission replaced cause it just stopped while in motion and struggled to start up again. It finally did, but it couldn't drive over 1st gear. I had to tow the car home. Also, few yrs back I had the head gasket replaced cause the car would shut off while I was driving. It would also not start up again if I had just turned off the engine. It needed time to cool off before restarting for me. And as of this moment, the car is in the shop again. This time it needs a new engine. While it's idling, it's making a very loud clunking sound. It's just never ending with this car. I know there were many recalls on the engine, exterior lighting and rear suspension but I never got the notices.
Ignition switch sticks in lock position. Was told by service department to jerk the steering wheel hard to the left.
