 In 8 years, there have been only a few minor issues with my Touareg TDI. One side turning light bulb and one rear taillight light bulb needed replacement.  There was also a minor electrical issue that was repaired under factory warranty when the Touareg was new.  Otherwise, there have been zero significant mechanical / electrical problems. A ruggedly handsome SUV that is fun to drive with more than ample acceleration (thanks to the 406 pound feet of torque / 7,700 lbs. of pulling capacity).  In addition, there is minimal or no noticeable body roll when negotiating corners/curves at speed.  Amazing road holding performance and immediate power delivery.  When driving the Touareg TDI, you feel like you are driving a serious, purpose-built rugged duty SUV with sedan-like handling.   The fit and finish and interior materials are world-class and so far, I have no squeaks or rattles.  I find that the standard stereo system is more than suitable and the navigation system is excellent.   It barrels down the highway or off-road with authority and I will keep my Touareg and drive it until the wheels fall off.
