Is the 2010 BMW M5 Worth Buying?
The 2010 BMW M5 offers an exhilarating driving experience powered by its iconic V10, but it is unequivocally one of the riskiest used car purchases you can make. This vehicle demands an extraordinary financial commitment for ongoing maintenance and has a high propensity for catastrophic, wallet-shrenching failures that can quickly exceed its market value.
While the 2010 BMW M5 offers an undeniably thrilling experience, its known, widespread, and catastrophically expensive reliability issues make it an extremely high-risk purchase.

2010 BMW M5 Recall History
2 recalls on record from NHTSA. Check your VIN atnhtsa.gov to see if the repair was performed.
ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES
BMW IS RECALLING CERTAIN MODEL YEAR 2004-2010 5-SERIES, MODEL YEAR 2004-2010 6-SERIES, MODEL YEAR 2006-2010 M5, AND MODEL YEAR 2007-2010 M6 VEHICLES. THE INSULATED BULKHEAD CONNECTOR FOR THE POSITIVE BATTERY CABLE MAY HAVE BEEN INCORRECTLY ATTACHED TO THE TRUNK FLOOR PANEL, WHICH CAN LEAD TO A LOOSENING OF THE BOLT CONNECTION. AS IT LOOSENS, AN INCREASE IN ELECTRICAL RESISTANCE AT THIS CABLE CONNECTION IS POSSIBLE AND COULD CAUSE THE CABLE CONNECTION TO OVERHEAT.
EXTERIOR LIGHTING:TAIL LIGHTS
BMW is recalling certain model year 2008 through 2010 528i, 535i, 550i, and M5 passenger cars manufactured from March 1, 2007, through December 31, 2009. Over time, increased resistance at the taillight electrical contact points may cause damage to the ground terminal and housing of the connector resulting in an intermittent or permanent loss of functionality of one or more rear lamp functions (tail, brake, turn-signal, reverse).
