I WAS ON MY WAY HOME FROM MAKING SOME ERRANDS, WENT TO TURN LEFT AND I THOUGHT THE CAR HAD CUT OFF OR SOMETHING. BECAUSE IT DIDN'T WANT TO TURN RIGHT, BUT TO MY SURPRISE IT WAS RUNNING. SO I MANAGE TO TURN IT BEFORE I HIT THE CURB. WHEN I GOT HOME I WAS ABLE TO SEE WHAT WAS WRONG. THE POWER STEERING QUIT WORKING. I LET THE CAR COOL A LITTLE AND GOT BACK IN IT AND THE POWER STEERING WAS WORKING AGAIN. COME TO FIND OUT THE POWER STEERING WORKS FOR ABOUT 10 MINUTES AND GOES OUT, UNTIL IT COOLS OFF. I STARTED LOOKING ON THE INTERNET AND FOUND OUT I'M NOT THE ONLY ONE WITH THIS PROBLEM. THIS IS VERY DANGEROUS AND I MEAN DANGEROUS. I CALLED MY MINI DEALER TO SEE IF THERE WERE A RECALL ON THIS PROBLEM AND THEY SAID THERE WASN'T. BUT I DID SEE THEY HAD A MINI DEALER NOTICE FOR THEM TO LOOK OUT FOR THIS PROBLEM, BUT NOT FIX FOR FREE. SO WE NEED A RECALL BEFORE SOMEONE GETS KILLED OR HURT, IF IT HASN'T ALREADY HAPPENED.

WHEN I RESTARTED IT, THE POWER STEERING WAS BACK BUT ONLY FOR A SHORT TIME. I HAD TO STOP AND START MY CAR A FEW MORE TIMES TO GET TO MY DESTINATION. THE PROBLEM OCCURRED CLOSER TO MY DESTINATION THEN MY HOME SO IT WAS SAFER TO GO THERE. IT EASILY COULD HAVE BEEN THE CAUSE OF AN ACCIDENT, ESPECIALLY ON THAT FIRST TURN OFF OF A 65 MPH ROAD. I'M NOT THAT STRONG. IT TOOK EVERYTHING I HAD NOT TO GO IN THE DITCH. LUCKILY NOTHING WAS COMING. I TOOK MY CAR IN FOR SERVICE TODAY. THEY REPLACED THE POWER STEERING PUMP. THERE WAS NO LEAD UP TO THIS INCIDENT. I HAD POWER STEERING AND IN A SECOND, I DIDN'T. *TR

15V660000 · Steering:electric Power Assist System

Oct 15, 2015

BMW of North America, LLC (BMW) is recalling certain model year 2002-2005 MINI Cooper and Cooper S vehicles and 2005 Cooper and Cooper S Convertible vehicles. The affected vehicles may experience temporary or permanent loss of the electro-hydraulic steering assistance.

Consequence & remedy

Consequence: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, potentially increasing the risk of a vehicle crash.

Remedy: MINI will notify owners, and dealers will inspect the electro-hydraulic power steering system, replacing the components and wiring, as necessary, free of charge. Interim notices were mailed to owners on December 10, 2015. Owners will receive a second notice when remedy parts become available. Owners may contact MINI customer service at 1-866-825-1525.

Jul 12, 2004

ON CERTAIN PASSENGER VEHICLES, THE FLAT TIRE MONITORING SYSTEM HAS NOT BEEN CORRECTLY PROGRAMMED. IN THE EVENT OF A FLAT TIRE, AN AUDIBLE SIGNAL WILL NOT SOUND TO ALERT THE DRIVER TO A FLAT TIRE.

Consequence & remedy

Consequence: DUE TO THE LACK OF AN AUDIBLE SIGNAL, THE DRIVER MAY NOT BE AWARE OF A FLAT TIRE, WHICH COULD INCREASE THE RISK OF A CRASH.

Remedy: DEALERS WILL REPROGRAM THE VEHICLE'S SOFTWARE IN ORDER TO ACTUATE THE FLAT TIRE MONITORING SYSTEM'S AUDIBLE SIGNAL. THE RECALL BEGAN OCTOBER 13, 2004. OWNERS SHOULD CONTACT MINI CUSTOMER RELATIONS AT 1-866-275-6464.

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
