Some dealers just have bad mechanics. I bought Kia Sportage 7 years ago. The dealer had to fix a minor scuff on the car that required removal of the driver's side rear wheel. When I picked the car up I noticed a vibration, especially on higher speeds. I took it back to the dealer and they couldn't find anything wrong. The vibration got worse so on my way back to the dealer I saw a lady behind me frantically waving her hands and pointing at my car. I got out at a red light and saw the rear wheel was almost off. The idiot who worked on my car didn't tighten the lugs. Needless to say, when I got to the dealer, after hand tightening the lugs, I was rather unpleasant. Mistakes are made but some are just ridiculous.
WOW! They didn't tighten the lug nuts on the rear wheel, you notice a problem and take it back to them, and they CANT FIND ANYTHING WRONG!! Holy chit. Now that is a dealership that should be avoided at all cost. What a bunch of morons.
