| Adaptive Cruise Control problems |
Adaptive cruise control dropped out, taking along with it the abs (warning light), stabilitrak (handling system) (warning light), collision prep (message). Dealer states the abs computer module failed, now in process of finding a replacement. Meanwhile, the abs, cruise control, and other systems mentioned here are inoperative. It may well be that this may be considered to be a component failure, not an inherent safety issue but under some driving conditions it is clearly a safety consideration.
At highway speeds with the adaptive cruise control engaged, the brakes are heavily applied when other vehicles or obstructions are not observed. Acc engaged on controlled access highway no vehicles or obstructions and random hard braking takes place. Vehicle has been taken to the dealer numerous times for this condition and dealer reports no problems.
