everyone has complaints about VW and they work. their poor close in vendors, god awful design ideas and pointless computers that seem to fail.
driving feedback on the other hand might be the reasons why many dub owners keep them and get new ones. the biggest complaints are from the ones who tried a VW after owning some solid cars and then overwelmed by cost of maintence, they sell the car and never wanted another one again. I hated the mk3 designs and the mk4 was varible, some cars are solid, jetta's seem to break more then GTI's. 2.0L suck the worst, next comes 1.8Ts and Vr6 were actually a solid motor. the 3.2 Vr6 was great aside from o2 sensors. thats what i learned wrenching at a VW dealership for a year.
the windows fall, due to bad clamps on the regulators, bad design in coil packs on the 1.8t's. bad coolant sensors ( $15 fix ) 2.0L burn oil over 60k. passat fuel pump recalls, leaves you with no starts. some passats you swap out radios and CEL comes on due to interferance with CAN BUS system.
keep in mind the 2.0L i refer to is not the new 2.0T,
I left the dealership before many 2.0T hit 20k. new GTI have squeeks and rattles like most cars. But they are inside the dash and doors. the radios on the mk5 seems to fail. the EOS has plenty of water leaks. every VW has a gas cap problem involving CEL, the TSB might of been put out.
but with all that said, every car has their problems. all auto surveys stated for every 100 cars made there was aleast 70 problems with those cars, all across the board with vendors. i think last time i saw VW's were at 130/100 problems.
get what you enjoy and like, just have a spare amount of money aside for repairs or become a good DIY because you will need it , a lot of repairs are simple 30 min repairs with a basic set of tools that can run you $500 at a dealership.
