I HAVE LOST POWER STEERING INTERMITTENTLY OVER THE PAST TWO MONTHS. IT CAUSES LOSS OF CONTROL AND MAKES THE CAR UNDRIVABLE AND THERE IS NO WARNING. I PULL OVER AND RESTART IT AND IT HAS POWER STEERING AGAIN. I AM AFRAID TO DRIVE IT ON THE FREEWAY. *TR

WAS TRAVELING AT NEIGHBORHOOD SPEED, TURNED INTO DRIVEWAY AND POWER ASSIST ON THE STEERING FAILED. HAD I BEEN AT SPEED THIS WOULD HAVE RESULTED IN HITTING A TREE NEXT TOT HE DRIVEWAY. THE CAR WAS ESSENTIALLY UNSTEERABLE WITHOUT TREMENDOUS FORCE, A CONDITION COMPLETELY UNEXPECTED. AFTER TURNING OFF THE VEHICLE AND RESTARTING IT, THE PROBLEM WAS NO LONGER THERE, SO OBVIOUSLY AN ELECTRICAL PROBLEM. THE PROBLEM RECURRED ABOUT A MONTH LATER WHILE DRIVING ON AN INTERSTATE HIGHWAY. I HAVE NO IDEA WHERE AS I DID NOT NOTICE IT UNTIL DECELERATING TO EXIT THE HIGHWAY AND THE CAR WAS VERY DIFFICULT TO STEER. AT THE BOTTOM OF THE RAMP, IT AGAIN BECAME NEARLY IMPOSSIBLE TO MANEUVER. AFTER TURNING IT OFF AND BACK ON, THE PROBLEM WAS GONE. THIS HAS RECURRED ON AND OFF EVER SINCE. A LOCAL BMW/MINI SPECIALIST MECHANIC INFORMED ME THAT THIS IS NOT AN INFREQUENT PROBLEM WITH 2005 MINI'S. HE INDICATED THE POWER STEERING FUNCTIONS FINE EXCEPT FOR INTERMITTENT ELECTRICAL PROBLEMS THAT CAUSE IT TO FAIL. THE PROBLEM HAS NOW COME BACK AND IS VERY FREQUENT. THIS IS PARTICULARLY TROUBLESOME AT LOW SPEEDS, AND WHILE PARKING. I FEEL THERE IS SUFFICIENT INSTANCE OF THIS TO WARRANT A RECALL AS OBVIOUSLY SOMETHING IS NOT RIGHT WITH THE DESIGN OR ENGINEERING OF THE POWER STEERING IN FAR MORE CASES THAT JUST MY VEHICLE. *TR

POWER STEERING STARTED FAILING APPROX. 3000 MILE AGO, AT LOWER SPEEDS THE POWER STEERING WOULD FAIL. NEEDED TO RESTART THE CAR TO HAVE POWER WORK AGAIN. FINALLY THE POWER STEERING FAN WOULD STAY ON WHEN THE CAR WAS TURNED OFF. TOOK THE CAR TO MINI DEALERSHIP, TECHNICIAN WAS APPROX. 30 FEET FROM CAR AND HE HAD A DIAGNOSIS . POWER STEERING PUMP HAD FAILED AND SO DID THE POWER STEERING FAN UNIT. SINCE THE CAR DID NOT PROPERLY SHUT DOWN I HAD TO REPLACE THE BATTERY. I HAD CONTACTED MINI USA WHEN THE PROBLEM STARTED AND THEY WOULD NOT DO ANYTHING UNTIL THE COULD REPLICATE THE ISSUE OF THE POWER STEERING FAILING. THIS WENT NOWHERE FAST. WHEN PUMP AND FAN FINALLY AGAIN THEY STILL WOULD NOTHING FOR ME AND WOULD NOT ACKNOWLEDGE ANY ISSUES WITH THE CAR. *TR

IT HAPPENS WITHOUT WARNING AND WITH NO NOTICE. BY LOOKING AT THIS WEBSITE AND ONLINE FORUMS I SEE THIS IS A ONGOING CONCERN,AND THAT THIS CONCERN RESULTED IN A RECALL IN CANADA.

AFTER IGNITING MY CAR, SOMETIMES POWER STEERING DOESN'T WORK. ALL I CAN DO AT THIS MOMENT IS THAT I TURN OFF AND RESTART MY CAR AGAIN. AND MOST OF TIMES IF I RESTART MY CAR, POWER STEERING WORKS FINE. ALSO POWER STEERING ONCE IN A WHILE STOPS TO WORK WHEN I DRIVE SLOWLY, E.G WHEN I DRIVE LOCAL. I HAVE TO RESTART MY CAR IN THIS CASE TOO. UNTIL A COUPLE OF DAYS AGO, I FELT THIS PROBLEM ONLY HAPPENED WHEN I IGNITED MY CAR OR DROVE LOCAL, SO I THOUGHT THIS IS A MINOR ISSUE AS LONG AS I CAN RESTART MY CAR SAFELY. BUT THE MOST DANGEROUS MOMENT OCCURRED TWO DAYS AGO WHEN I WAS MAKING A TURN TO EXIT ON PARKWAY. SUDDENLY IT WAS VERY HARD TO CONTROL THE CAR ON HIGHWAY, AND I HAD TO STOP AT SIDE ROAD AND RESTART. I BROUGHT MY CAR TO LOCAL MECHANIC AND HAD HIM EXAMINE IT YESTERDAY. HE SAID POWER STEERING WHEEL PUMP NEEDS TO BE REPLACED. *TT
POWER STEERING PUMP FAILED AND LOST STEERING ABILITY. THE RELAY FOR THE COOLING FAN REMAINED IN THE CLOSED POSITION CAUSING THE BATTERY TO FAIL. I HAD TO REPLACE THE POWER STEERING PUMP AND BATTERY. THERE HAVE BEEN MANY COMPLAINTS OF THE SAME PROBLEM. THERE SHOULD BE A RECALL TO FIX THIS BEFORE SOMEONE GETS KILLED.

115V205000 · Air Bags:frontal
Apr 6, 2015
BMW of North America, LLC (BMW) is recalling certain model year 2005-2006 MINI Cooper and Cooper S vehicles manufactured January 5, 2005, to November 28, 2006, and 2005-2008 MINI Cooper Convertible and Cooper S Convertible vehicles manufactured January 5, 2005, to July 31, 2008. Due to manufacturing, installation, and exposure issues, the front passenger seat occupant detection mat may not function properly and, as a result, the front passenger air bag may not deploy in a crash.
Consequence & remedy
Consequence: An improperly functioning mat may cause the passenger frontal air bag to be inactive when the seat is occupied, and in the event of a crash, the air bag will not deploy, increasing the passenger's risk of injury.
Remedy: MINI will notify owners, and dealers will replace the front passenger seat occupant detection mat, free of charge. The recall began on October 12, 2015. Owners may contact MINI customer service at 1-866-825-1525.

Status: closed (inferred from source dates) · Steering; Steering:electric Power Assist System; Steering:hydraulic Power Assist System; Steering:hydraulic Power Assist:pump
The Office of Defects Investigation (ODI) originally opened the investigation of loss of power steering assist in model year (MY) 2004 and 2005 Mini Cooper as Preliminary Evaluation PE10-038.The investigation was upgraded to Engineering Analysis EA11-005 in May, 2011.During EA11-005 the scope was expanded to include MY 2002 and 2003 vehicles that use the same steering system.The subject vehicles now include MY 2002, the first year BMW sold MINI in the U.S., through mid-MY 2005 covering approximately 109,000 vehicles.The subject vehicles use an electrically driven pump to provide hydraulic pressure to a conventional rack-and-pinion steering gear.A pump, the electric motor, and an electronic control unit (ECU) are housed in a single component BMW calls a Power Pack.The investigation focused on contaminant-induced failure of the ECU resulting in a loss of assist without warning.When assist is lost mechanical steering is retained however increased steering effort is required to keep the vehicle on an intended path.Some consumers reported that restarting the vehicle (cycling the ignition switch) would often reinstate the steering assist.Additionally, and by design, assist can also reinstate during the drive cycle in limited circumstances.The unexpected loss of assist, and/or possibly the reinstatement of assist while driving, may contribute to a loss of vehicle control in certain driving situations.During MY 2005 production BMW introduced a revised Power Pack design (the ECU incorporated a conformal coating of the circuit board) which resulted in a significant reduction in failures.ODI identified 20 reports describing crashes consistent with a loss of power assist event possibly caused by a failure of the Power Pack.Two reports alleged an injury however both were minor in nature and did not require emergency treatment (a subsequent doctor's visit occurred in one case).Ten of these reports described low speed crashes with minimal, or in most cases no property or vehicle damage (e.g., striking a movable barrier in a parking lot).Additionally 27 other reports alleged or indicated that a crash occurred due to a Power Pack failure however in reviewing these reports, ODI either 1) was unable to confirm that a crash actually occurred (8 reports), or 2) determined that the crash circumstances (e.g., adverse road/weather conditions) or cause (e.g., the crash was caused by steering linkage failure) were not attributable to a Power Pack failure (19 reports).Throughout the investigation BMW maintained that loss of assist in the subject vehicles did not constitute a safety related defect, noting that the subject vehicles are smaller, light weight vehicles that can be reasonably controlled when assist is lost.In May 2013 BMW launched a 13 year/150,000 mile extended warranty coverage utilizing the redesigned Power Pack as a replacement part.ODI continued its investigation.In July 2014 BMW provided ODI a status of the ongoing extended warranty program, and in May 2015 ODI requested an update of complaint data.Following a review of the provided data, ODI informed BMW of its assessment that loss of steering assist failures were not adequately resolved by an extended warranty program.On October 12, 2015 BMW notified NHTSA that it would conduct a safety recall (15V-660) on approximately 86,000 subject vehicles not previously remedied with the new design Power Pack through regular or extended warranty programs.The recall covers MY 2002-2005 MINI Cooper, MY 2002-2005 MINI Cooper S, and MY 2005 MINI Cooper/Cooper S convertibles manufactured through Feb 9, 2005.Vehicles produced after this date are not included si
