Random engine hesitancy reducing acceleration while driving. Vehicle maintained by the dealer for all scheduled maintenance and service visits. Within 30 days of a manufacture's repair that dealt with the HVAC and air filter AND a service visit to change oil and rotate tires, the hesitancy during driving was more pronounced. The dealer's service center stated the air filter was flooded from an HVAC leak and a clog. I have found similar owners have had problems like this and VW will not address it systemically. I otherwise enjoy my vehicle, but am concerned that it will not accelerate when needed and is potentially dangerous without warning. It should not take loss of life or property to have this corrected.

After less than four years of ownership, and outside of the 3 year/36,000 mile warranty, the adaptive cruise control module(s) failed for no apparent reason, rendering the entire cruise control system inactive. The nature of the safety systems in Volkswagen is such that if one system is not working, none will - thus, the 'front assist' collision avoidance system is no longer active, which is an integral part of the active safety technology in the Touareg. In addition, basic speed modulation of conventional cruise control is also unavailable. The reliability of basic systems such as cruise control should not be contingent upon immensely expensive, and overly complicated technological components.
