“My 2004 vw Jetta 1.8 turbo which I purchased new is having transmission problems. My cat has only 66,000 miles in it and has been well maintained. In the past two years I have replaced the fuel pump, battery, catalytic converter, numerous vacuum leaks ect...but a transmission???? Volkswagen needs to issue a recall as this is way to common!! Please help!”

“I drive a 2004 Volkswagen Jetta and in 2008 it began smelling of crayons. The smell has slowly progressed over the years to the point of nauseating me and my fellow passengers. This morning on my drive to work the smell was so potent that I had to pull over twice to throw up. When other passengers enter my car, they experience head aches, extreme allergy symptoms, and sick to the stomach feelings. I've reached out multiple times to Volkswagen through both dealer and corporate media. Dealerships say there is no fix for this smell (caused by an outgassing of sound deadening material). …”

“1. Coolant light came on (1st time). 2. Brought the car to the dealership, they pressure tested the system and reported no leaks. They topped the system and charged me $100 3. Coolant light came on (2nd time). 4. Brought car back to dealership, they now report that problem as the EGR cooler. They suggested I contact vw of canada to discuss this failure as it is becoming very common. 5. Called vwoc and they would not assist with this very expensive repair. Jb”

“I have a 2001 vw Jetta. When it gets hot outside (sometimes) the vehicle loses power while driving then regains it. Also when it starts acting up if u stop the car will shut off and u gave to restart it. I have took the care to vw they don't know what is wrong with it. Replaced several parts (throttle body, dwn flow 02 sensor, coil pack plugs, catalytic converter) still don't know. The only thing the computer is showing is cooling system performance. One vw dealer said there was a wiring problem that sometimes causes similar problems. …”

“Clutch failed at 52k miles, was told it was not covered under warrant due to wear and tear, mechanic deemed it a faulty part, vw said it only covered manufacturer defects up to 50k miles, paid $1500 to replace clutch. Trunk pops open randomly and latch makes clicking noises. Air cooling sensor needs to be replaced, my car is reading a running temp of -54 when it should be 160. Car stalls if I turn it off after driving more than a few miles then doesn't turn over if the engine cuts off. Black smoke pours out of tailpipe and it burns double the gas it should. …”
