NHTSA Complaint #10780458 — 2012 BUICK LACROSSE

WE HAVE A 2012 BUICK LACROSSE WITH EASSIST. WHEN DRIVING AT AROUND 65 MPH ON THE HIGHWAY WITHOUT THE CRUISE CONTROL ENGAGED THE VEHICLE DOOR LOCKS SUDDENLY UNLOCK AND LOCK, THE CAR DOWNSHIFTS AND THE RPMS GO WAY UP AND A LIGHT COMES ON THAT SAYS "SERVICE POWER STEERING". WE HAVE TAKEN IT TO THE DEALERSHIP AT LEAST 3 TIMES FOR THIS ISSUE AND THEY SAY THAT BECAUSE THERE IS NO CODE DROPPED IN THE COMPUTER WHEN IT DOES IT AND THEY DON'T HAVE IT HAPPEN WHEN THEY TEST DRIVE IT, THEY DON'T KNOW WHAT TO DO. THE CAR HAS 53K MILES ON IT AND THIS HAS PROBABLY HAPPENED ABOUT 2 DOZEN TIMES. THE ENTIRE EVENT LASTS FOR ABOUT 10 SECONDS BUT IT IS VARY SCARY WHEN YOU ARE CRUSING ALONG AT 65+ MPH AND ALL OF THESE THESE EVENTS JUST HAPPEN, ESPECIALLY THE HIGH RPMS, BECAUSE IT'S LIKE ENGINE BRAKING AS THE TRANSMISSION DOWNSHIFTS.
