Car switches into all 4w and higher by itself. I had been to a dealership 3 times in one year for which they were unable to find the problem. Now my warranty is up. After that I took it to a transmission shop where they supposedly fixed the problem for over 800. $ a week later it did it again. Now I have the 4wd disconnected for safety reasons. I would be driving on the freeway at 60-75 mph and if would switch and not come out no matter what I do. I have owned this vehicle for almost 5 years and it has done this the whole time. I am a single mom and I drive my 17 and 7 year old around in this car. Even with it disconnected it still tries to switch. There is no specific time, temperature, or other reason this happens. It has happened when I turn on the car and sometimes I can go a couple of weeks and other times it happens daily. I also have had my lights not go on for no reason and also the doors lock and can only be unlocked by using the key. And the hatchback will not open at all when this happens. Electrical?? help!!.

With about 1100 miles on my brand new car , the 4wd light came on. Not happy about this purchase.
When new, the vehicle would unexpectedly go into 4-wheel drive in a slight left turn making the vehicle very hard to steer. I took it back to the dealer of purchase and he reported they could not find the problem. After my warranty ran out he reported the following; 611 encoder actuator, 7764 cst, 1 89059275 actuator. He replaced the actuator at a cost of $275. 30 for the actuator and $221. 90 labor for a total of 497. 20 at my cost! here it is several years later and the vehicle is still doing this occasionally dangerous maneuver. I can't let my wife drive my vehicle because of the safety factor of this happening in heavy traffic. I guess I have no choice but live with this?.
