Current mileage is 26. 985 1. Car seems to lose power when accelerating and hesitates (almost shutting down), it happens randomly while driving as well and is now happening more and more often. It' very dangerous when crossing intersections or making a right on red and especially dangerous when accelerating to enter a highway. 2. Rear suspension makes strange noises upon backing up/stopping; 3. Very bad odor coming from a/c vents. . . . Disgusting, almost smells like plastic burning or burning rotten eggs; 4. I hear strange noises in the back brakes, not constant but random and getting louder when it does happen; 5. Wiper fluid not working, I've been told this is a recall issue; 6. The automatic dashboard lights are constantly changing, most especially when turning the wipers on/off. It doesn't seem to matter if you're in complete darkness or daylight. 7. Sometimes the car will not lock until you put the key back in the ignition, restart the car, take it out of park and put it back in park. Sometimes I have to do this 2 or 3 times, each time getting back out of the car to try to lock it. 8. Steering this car on the highway at highway speeds is difficult. . . The car swerves and if it's a windy day it's beyond difficult to keep this car in the lane. Very dangerous. 9. The radio turns itself on and off as it pleases. It took me years to be able to finally purchase a new car and now there are not only 6 recalls on the car but I also have all the additional problems listed above. There's a 45 day wait to have the recalls repaired and event with that I am now going to have to take a day off of work without pay to get this crap all fixed! I feel like I have wasted my money. So much for expecting reliability and quality.
