I went in to have them check my two front turn signals... both burned out within 2 weeks of each other. One of their technicans looked at it and told the service writer that I had a major problem with some turn signal control module...that it was going to be a very expensive repair. At this point, I just drove over to the dealer, had a mechanic look at it on the spot (as opposed to waiting for my appointment later in the month), replace 2 bulbs, and $14.00 and 20 minutes later (those front bulbs are funky and expensive) I'm outta there... Absolutely no problem with any control module, etc... So, I couldn't help but think to myself why would I trust them making major modifications (and, costly ones at that) to a pretty fine automobile when they couldn't diagnose a problem as simple as a burned out bulb? Quite frankly, it scared the crap out of me.
