Headlamps quit working while driving at night. Both headlamps did not turn on and I had to drive with the fog lights. I checked the relay and fuses which were all okay. This morning, they did work. I've researched other owner forums of which this incident has happened from a bad ground from an overheated fuse box in the engine compartment, with owners driving at night and driving lights going out inexplicably, which could lead to serious injury.

Upon complition of the recall servicing my car would not start the car's digital imformation center said service colume lock.....this problem was created by the dealership that performed the recall now for the last few months when ever I excellerate quickly I get an service active handling message and the brakes do apply and I get an unstable ride for a short period of time, after I come to a stop and cut the motor off the (dic) digital imformation center will no longer show the message. As a result of the recall servicing I have had constance errow messages stating....service colume lock, and service active handling. When the massage center reads service colume lock the car won't start, these problems started immeadily after the recall servicing. Please advised me of what can be done to correct this most distrubing problem....the dealership is not owning the problem they surely caused.
