|Interior Lighting problems|
Instrument cluster failure. Lights fail to illuminate at night when knob is turn to headlight position.
Instrument lights do not light up. Instruments cannot be seen at night including speedometer and gas gage. Potential consequences are running out of fuel or exceeding the safe speed limits because speedometer is not visible. The problem has gotten worst with time. This has been a problem since the car was new and dealers blame the problem on light bulb problems. Sometime rapping the instrument cluster cause the lights to come back on indicating that this is a problem with the connection and not the bulbs. This appears to be a defect with the bulb connections as the problem is recurring and the dealers are not truly fixing the source of the problem.
Numerous problems with exterior and interior lighting. Most importantly the left turn signal continually goes out without notice. Sometime the interior left turn lights up and sometimes it doesn't. Other times the interior left turn light goes completely out placing me and my children in great danger. Also I made a left turn and the steering went out just as I entered the beltway and was unable steer the vehicle.
Interior light failed. Yh.
