I've told the story every time the words Volkswagen and "dependable" come up...
I leased a simple 8v/5mt 2002 Jetta GLS back when it was brand new. What a turd! By the time I turned it in at 30k, it was ready for the crusher. Some of it's "features":
-It would consume almost all its oil between oil changes from new. Oil changes were every 5k miles. I found this out the hard way when the oil light came on around 4k miles. It held 3.7 qts if IIRC, and it would burn through 3 of them before the oil change. Dealer said "This is normal for the 8V engines, they do that".
-Right around 5k miles, the driver's window regulator broke, causing the window to fall into the door and shatter. Just in time for a thunderstorm, too. Had to leave the car at the dealer for a few days because the parts were on backorder from the same thing happening to all the other VW's in the country.
-The Michelins that came on it were completely dry rotted by 20k miles. That's probably not VW's fault, but since the very same tires on my mom's Maxima didn't do that, I'm going with it's VW's fault.
-Exhaust system was rotting apart by 20k miles. The center hanger was a rusted nugget and fused with the body of the car.
-It made a terrible rattling sound around 30mph or 3000 rpm in any gear, like the flywheel was trying to leave. That started around 15k miles. Dealer couldn't figure it, so it stayed that way until it got turned in.
-I cannot count how many headlights and taillights I replaced in that thing, they just kept burning out!
-The gauges worked when they felt like it. You could be going down the highway doing 65mph, and all the gauges would flop back to zero. Then, at random, they would come back. Car never skipped a beat.
-Front seat heaters couldn't be turned up to full strength because they would burn your butt. No, really. There was a TSB and possibly a lawsuit or two because of this. I read somewhere that a lady had severe burns on her butt because the heater coils burned through the seat fabric and burned her! I believe it.
Only remarkable thing about the car is that the CEL never went on once. All of that stuff and more happened to it and it never went on once!
If they couldn't get a basic 8V Jetta right, I can't imagine what a more complex turbo, VR6, or W8 one would be like to own. I've heard of similar quality issues with newer Jettas too, but then again I've hears good things about the newer GTI's too. All I know is that I'm staying the hell away from VW products based on the three years of hell I endured with mine.
