Tl* the contact owns a 2007 buick lacrosse. the contact stated that the front passenger side door lock actuator failed, causing the door to remain locked at all times. approximately one month later, the rear driver side door lock actuator also failed. the vehicle was taken to an independent mechanic who diagnosed that the door actuators needed to be replaced. the vehicle was not repaired. the local dealer and manufacturer were not notified. the failure mileage was 170,000.

Tl* the contact owns a 2008 buick lacrosse. the contact stated that while parked, when trying to open the front drivers side door, the door handle became detached from the vehicle. the lock and the insides of the handle were still connected, but the door handle was separated. the vehicle was not diagnosed or repaired. the manufacturer was made aware of the failure. the failure mileage was 113,729.

1.the door locks work intermittently with or without the key fob. the interior button as well as when put into drive or park does not always engage or unlock. i had it looked at and was informed it is the door lock actuators that are faulty and need to be replaced in all 4 doors. 2.the windshield washer fluid does not work at all. the washer motor does not run and needs to be replaced. *tr

While driving at night both headlights failed to work without warning headlight relay failed several incidents posted on line. after arriving at work was unable to exit the vehicle because both inside and outside door handles failed to open the door. car is currently at a body shop attempting to open the door. *tr

While driving on the highway in the rain, my headlights went out. i was terrified. turning the switch on and off would not fix the problem. i took the car to the dealership. they said they could not duplicate the problem and would not fix it. i had taken the car to the dealership shortly after purchase in 2009 and had complained of leaking seal on the top edge of the driver's side door in the rain. water would drip all over my left arm, shoulder and arm rest. they said they could not duplicate the problem and would not fix it. now the headlights will refuse to work on an intermittent basis. the dealership will not fix it. the dash reads headlights suggested but they will not come on. i can use the dimmer on the steering column and the bright lights will work, but driving with bright lights into oncoming traffic is dangerous. i need to have a dealer fix this problem. i took the car through a car wash for the first time the other day and the lights have been acting up again. please have someone contact me and authorize repairs at the dealership. i am afraid to drive even a short distance at night not knowing when my headlights will suddenly go out again. it has happened several times now. it really scares me and concerns me that a dealership would not repair the problem. *tr updated 09/10/13*lj the consumer also stated there was a noise coming from the steering, a squeaking noise coming from the dash area, and water would drip through the top door, every time it rained. also, there was a vibration issue, so the dealer replaced the tires, but it didn't resolve the issue.
