Adaptive Cruise Control Problems of Buick Lacrosse

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.

So many issues with the Buick. Made of glass. First I had no coolant line and I took it to be inspected before at, baumen Ford and they said everything was fine with it. Turns out needed new coolant line, head gasket, timing cover, and switch. 5 new tires, rebuilt transmission, epc solenoid, transmission lines, rear pivot, left front wheel barring, formed band, and many many more. Currently with everything replaced and more that I haven’t listed/can’t state because don’t know the term. Already has costed me 10k. And still have issues, with the app, code p1125, p2120, p2138, & c0240. Need to inspect these car models from 2003-2009 as they all have similar issues and nothing has been done.

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.
