Here's some tips for dealing with your dealer's service department that will make things easier on everyone:
1. When dealing with squeaks and rattles, see if you can get the shop foreman, service manager, or better yet, technician to ride with you so that you can point out the nusiance that you are referring to. Nothing is more annoying to us than to see "Check rattle" on a repair order with no other info. Chances are, we will fix the wrong problem.
2. Whatever the problem is, give as much info as possible. If we have a better idea as to where to start, the sooner you will have your car back. I cannot tell you how many times i have wanted to beat my service writer into a pulp for not clarifying that the engine hiccup happened once just before they got to the gas station with the fuel guage 3 inches past 'E' :roll: or something along those lines.
3.
DO NOT ARGUE WITH US!!! Technology in cars changes every couple of months and with the advanced levels of some of the stuff, electrical gremlins can be a pain in the ass to track down. And if you think the reason your battery light is on is because the battery is dead, and not the alternator, then take your car and replace the battery. You can pay is another diagnostic fee and towing bill in a couple days when the new battery goes dead. If you think you can diagnose a car, then why did you bring it to us? You don't argue with your doctor, why would you argue with your mechanic?????
4. If you know we are going to have to get into your trunk, please unload it BEFORE dropping off your car. at least once a week i have to deal with a packrat who things their trunk is another place for crap that won't fit anywhere else. It makes getting to the battery and spare tire a job within itself. I just wish i could charge for removing and installing junk from the trunk :roll:
5. If you are going to wait on your car to be worked on, please, keep it short. Oil services, light bulbs, etc. Packing 15 lines on a RO that you are going to wait on is extremely rude. Contrary to popular belief, when you wait on your car, you are on the technician's time. Not yours. So don't ask how much longer it's going to be. This just pisses us off and depending on how our day is going, may induce us to take a little more time.
6. Read the owner's manual. I (and i speak for tens of thousands of techs worldwide when i say this) have grown weary of filling windshield washer bottles because someone thought the indicator light for it was the check engine light :roll: It wastes your time to swing by the dealer, and ours to abandon the job we are on to tend to the painfully helpless. Mainly women are the offenders of this one.
Those are the big 6. There are more, but i'm getting pissed off just thinking about them

where's my beer? i need one now.
