Not ratedNHTSA has no overall rating for this year
NHTSA's VIN data lists these trims for the 2007 R-Class. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 67 complaints with NHTSA about the 2007 R-Class. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 5 recall campaigns for the 2007 R-Class over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2006-2012 ML, GL, and R-Class vehicles. Please refer to MBUSA's recall report for specific vehicle model details. Moisture may accumulate and cause corrosion in the brake booster housing unit, which can result in reduced brake performance or brake failure.
Risk: Reduced brake performance or brake failure can increase the risk of a crash.
Remedy: Owners are advised not to drive their vehicles until the remedy has been performed. Dealers will remove the rubber sleeve, inspect the brake booster, and as necessary, replace the brake booster. All repairs will be performed free of charge. Owner notification letters were mailed on May 24, 2024. Owners may contact MBUSA customer service at 1-800-367-6372. MMUSA's number for this recall is 2024050001/2.

MERCEDES-BENZ IS RECALLING MY 2006-2008 M-CLASS, R-CLASS, MY 2005-2009 SLK-CLASS, MY 2005-2008 C-CLASS, MY 2003-2004 AND 2006-2008 CLK-CLASS, MY 2003-2008 E-CLASS, MY 2004 AND 2008 CL-CLASS, MY 2008 CLS-CLASS, MY 2004 AND 2007-2008 S-CLASS, MY 2003 G-CLASS, AND MY 2003-2004, 2006 AND 2009 SL-CLASS VEHICLES. A SOFTWARE CALIBRATION NUMBER (SCN) CODING RECEIVED ON THE AFFECTED VEHICLES DURING A RECENT WORKSHOP VISIT WAS INCORRECT. DEPENDING ON THE MODEL YEAR AND MODEL AFFECTED, THE RESULTS OF AN INCORRECT SCN CODING CAN AFFECT A NUMBER OF VEHICLE SAFETY AND EMISSION FUNCTIONS INCLUDING THE FOLLOWING TYPES OF FUNCTIONS: (1) THE FUEL GAUGE READINGS MAY BE INCORRECT; (2) A STUCK FUEL-LEVEL SENSOR MAY NOT BE DISPLAYED IN THE INSTRUMENT CLUSTER; (3) THE OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND, (4) THE SPEEDOMETER MAY BE OUT OF TOLERANCE.
Risk: IN THE EVENT OF A VEHICLE CRASH, THE ELECTRICAL FUEL PUMP MAY NOT RECEIVE A CRASH SIGNAL THAT IS REQUIRED FOR THE FUEL PUMP TO DISCONNECT AND PREVENT FUTURE FUEL DELIVERY AS DESIGNED.
Remedy: DEALERS WILL RECODE THE SCN FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 30, 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH DIESEL ENGINES, THE CRANKSHAFT SENSOR COULD FAIL DUE TO SEPARATION OF BOND WIRES FROM THE LEAD FRAME IN THE SENSOR. THIS RESULTS IN AN INTERRUPTION IN THE ELECTRICAL CONNECTION IN THE CHIP HOUSING OF THE SENSOR.
Risk: WHEN THIS HAPPENS, THE VEHICLE MAY LOSE POWER RATHER THAN ENTER A LIMP-HOME MODE. IN ADDITION, THE VEHICLE CANNOT BE RESTARTED AFTER FAILURE OF THE ELECTRICAL CONNECTION IN THE SENSOR, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE CRANKSHAFT SENSOR. THE RECALL BEGAN ON FEBRUARY 4, 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
ON CERTAIN VEHICLES, THE ACCELERATOR PEDAL MIGHT NOT HAVE BEEN FULLY FASTENED TO ITS MOUNTING STUDS.
Risk: OVER TIME, THE PEDAL MAY NOT MAINTAIN A CONSISTENT PEDAL POSITION, WHICH COULD MAKE IT MORE DIFFICULT TO OPERATE THE ACCELERATOR.
Remedy: DEALERS WILL INSPECT AND, IF NECESSARY, INSTALL THE MOUNTING NUTS OF THE ACCELERATOR PEDAL. THE RECALL BEGAN ON JANUARY 16, 2007. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
