This TSB applies to 2010 Volkswagen Touareg models with a no-crank condition. When the vehicle is unlocked by using the key in the driver door handle and 15 seconds elapse without the ignition key being inserted into the ignition switch, the alarm will go off and the start signal will become prohibited.
Owners of 2013 Chevy Equinox vehicles may comment on an intermittent no-crank issue. The design of the key and fob is to have the key extended straight out of the fob. If the key is not in the fully locked-open position at the fob, and the head of the key is angled down, the engine will not crank.
