Adaptive cruise control - vehicle follows vehicle in front way too close. the interval following distance is 1.2 seconds when set to near and 1.5 seconds when set to far. this is way too close as most states specify no less than 3 seconds. buick has no answer. please help...
Tl* the contact owns a 2015 buick lacrosse. while attempting to park, the vehicle independently surged forward, went over a railroad cross tie, and crashed into a tree. a police report was not filed. the air bags did not deploy. no injuries were sustained. the vehicle was repaired. the manufacturer was notified of the failure. updated 01/21/16*lj *js
