Open the full vehicle complaint log (all categories)I was involved in an accident with my 2019 Volvo xc40. I believe the cause of the accident was due to the emergency braking system that activated when I hit water that accumulated on the road I was traveling. I was accelerating and the braking caused the vehicle to swerve uncontrollably resulting in some minor body damage to the passenger side as contact was made with some roadside objects. Unfortunately the incident caused over $10,000.00 in front end damages, which is covered by my insurance. This emergency braking i. e. forward collision avoidance automatic emergency braking, has the possibility of causing a more severe accident. I believe a software update was instituted, but the Volvo dealership never mentioned this update when I had my car serviced the past 3 years.
PILOT ASSIST FUNCTION DISENGAGES SUDDENLY WITHOUT WARNING. THIS IS DIFFERENT FROM THE EXPECTED OPERATION WHERE THE SYSTEM'S STEERING ASSISTANCE WILL GO INTO STANDBY UPON LOSING LANE MARKING INPUTS. WHILE THE SYSTEM DOES OCCASIONALLY ENTER NORMAL 'STANDBY' INDICATED BY THE GREEN STEERING WHEEL ICON TURNING GREY, IT ALSO OCCASIONALLY TURNS OFF ENTIRELY WITHOUT WARNING (INCLUDING AUTO THROTTLE CONTROL), WHICH IS INDICATED ONLY BY AN UNEXPECTED DECELERATION AND BY THE STEERING WHEEL ICON AND FOLLOWING DISTANCE INDICATORS BOTH SUDDENLY DISAPPEARING FROM THE INDICATOR PANEL. IMMEDIATELY ATTEMPTING TO REACTIVATE PILOT ASSIST WILL USUALLY RESULT IN AN 'UNAVAILABLE' INDICATION; HOWEVER, WAITING ABOUT 10 SECONDS WILL USUALLY RESULT IN BEING ABLE TO REACTIVATE FULL PILOT ASSIST FUNCTION. THIS HAPPENS BOTH CITY AND HIGHWAY DRIVING.
TL* THE CONTACT OWNS A 2019 VOLVO XC40. THE CONTACT STATED THAT THE FORWARD COLLISION AVOIDANCE FEATURE FAILED TO OPERATE PROPERLY. WHILE SLOWING THE VEHICLE DOWN TO 20 MPH, THE VEHICLE WOULD BEGIN ACCELERATING INDEPENDENTLY. ALL THE WARNING INDICATORS STARTED TO ILLUMINATE, A BEEPING NOISE OCCURRED, AND THE STEERING WHEEL WOULD REDIRECT INDEPENDENTLY. THE FAILURE RECURRED NUMEROUS TIMES. THE CONTACT TOOK THE VEHICLE TO KLINE NISSAN (3090 HWY 61 N, MAPLEWOOD, MN 55109, (877) 284-5230) TO BE DIAGNOSED, BUT NO FAILURE CODES WERE FOUND. THE TECHNICIAN INFORMED THE CONTACT THAT THERE MUST BE A GLITCH AND THE SERVICE MANAGER STATED THAT THERE WAS NO FAILURE WITH THE VEHICLE. THE TECHNICIAN UPDATED THE SOFTWARE. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS APPROXIMATELY 2,000.
