The car idles very high and then accelerates to higher speeds without touching the accelerator pedal. There is a high acceleration boosts and spurts when first accelerating from a stopped position, causing car to lunge forward at high speeds. The car refuses to start when not used daily, such as a problem with the starter or the alternator, but no problems have been found with either parts upon inspections by a mechanic. Front axles pop when turning. Key is hard to disengage or remove from the ignition. Brakes are constantly squealing and wear every 3-6 months regardless f how the car is driven. Though it may or not be a problem for some, the fold down seats in the rear seat do not have a disengage lever from the trunk. Over-head dome light does not function properly and has faulty wiring, so that even though all doors are closed the dome light never shuts off. There is constantly a fuse light that flashes in my dash, though all fuses have been checked numerous times and all are in perfect working order, though they have been replaced, the warning light still flashes. The utility outlet/cigarette lighter outlet doesn't and has not ever worked since the car was bought in 2004. Fuses have been replaced multiple times, but the problem still has not been fixed. Water leaks in from rain or windshield wipers causing musty odor in the car. Car constantly over-heats during travel over 35-40 miles and leaks anti-freeze, though no leaks or pin holes of any kind could be found. Trunk sticks making it hard to open or disengage, caused key to be broken off inside the trunk lock.
