“I have noticed a burning crayon smell in my 2003 vw Jetta for a few months. I have had the car detailed and had the dealer clean the AC ducts yet the smell remains - and gets stronger in hot/humid weather days. I see others have listed complaints of the same nature - and the sound deadener material under the carpet seems to be the culprit. I am concerned that this will affect breathing and could be toxic.”

“Numerous times that the engine light has come on my 2003 Jetta. First visit was 9/12/02. The others were: 2/21/03, 6/13/03, 10/21/04, 1/6/05, 12/14/05, 12/21/05, 1/9/06, 1/13/06. It is currently on and is waiting for a cat. Converter. They charged me to hook up to computer, replaced all coils & spark plugs and the light is still on.”

“Rattling noise in the engine, oil pump was not pumping oil and camshaft chain tensioner (timing belt) rattling from lack of oil. I was informed I needed to replace engine due to metal particles and carbon in the oil pan.”

“I started experiencing a hot spot in the driver's heated seat in the fall of 2012. I have to put a cushion between my right leg and the seat or it will nearly burn. I have also been having an issue with either the o2 sensor or catalytic converter whenever it rains and it's cool weather. The car will lose power, sputter and lurch until it has been running for a while then it acts normally. Finally, for the past two months the rear door locks will not open with the keyless entry or by hitting the lock/unlock button on the door. …”

“The oil pump quit, causing the oil pressure lamp to come on. The vehicle is still under warranty, but since I cannot produce all of the receipts for oil changes since I purchased the vehicle, they will not cover the warranty. The dealer says that the failure was due to oil sludge. I was not informed that I had to keep receipts for oil changes durring the lifetime of the vehicle.”
