I've already had the car in to the dealer once for the right front turn signal going out. They replaced the bulb about a month a go and now the problem is back again. It seems more like a bad connection than a bulb issue. Any clues?

now it has spread to the right rear turn signal and the right rear tail light

...they first replaced the hazard turn signal switch. "Tech found R/F bulb inoperable after replacing switch. Tech found R/F bulb inop. Found bulb socket corroded. Replaced bulb and socket. System working per design."

Why would the bulb socket be corroded on an 8 month old car? Had map light bulb replaced as well and L/F bulb was replaced in August. Bad batch of bulbs?

Took dealer 3-4 tries ... basically took things apart and put them back together better .. or something like that

Dealer replaced bulb and bulb enclosure. No problems since.

had dealer fix on my 20k service. They replaced a faulty socket on one side that was causing the other side to go bad, or so they tell me.. no probs since.
