the front right turn signal will fail for a week work the next week then fail again for god knows how long.
DRL failed. Cost nearly $100 in labor to replace due to design -- front bumper has to be be partially removed.
Driver's side rear light melted into light socket. Picked up a replacement at AutoZone for $34. Now passenger turn signal light has gone out. The top of each head light cover is discolored, it looks like a heat related effect on the top of each sealed plastic cover.
Had to replace mine. I went to a auto parts store and bought mine, and had them replaced for about $400-$500 for both. At the dealer one headlight bulb is $500 each. To replace them the front bumper has to come off no other way to get to the front headlights.
Front timing cover seal leaking, valve cover gaskets leaking, driver seat track broken/loose, passenger vent rattling/broken.
Front passenger Running light went out. Bought the replacement bulb (#5201) and followed video how to access and remove head light unit;so far so good. But when I went to remove old bulb & replace new bulb was another story! Seems impossible to get it to clip/plug in without doing damage! Is there a special way or tool needed to get it to clip in? Still trying to figure this one out! I noticed it was every weak a couple of days before it failed.
Front headlight went out. Replaced both, one week later left one out again. Then right blinker went out. Replaced it worked for 2 days. Now break lights is out!!
