2011 Volvo S80

The 2.5L inline-five turbocharged engine (T5) uses a timing belt with a service interval of approximately 105,000 miles. Failure to replace the belt on time can result in catastrophic interference engine damage. The water pump, driven by the timing belt, is a common failure point and can leak coolant onto the belt, accelerating belt deterioration.

Replace the timing belt, water pump, tensioner, and all idler pulleys as a complete kit. This is a critical preventive maintenance item. The thermostat should also be replaced during the service. If the belt has already failed, the cylinder head must be removed to inspect for bent valves and piston damage.

The electronic throttle module can fail, causing erratic idle speed, stalling, reduced power mode (limp mode), and the check engine light to illuminate. In some cases, the throttle becomes unresponsive during acceleration, which is a safety hazard. Earlier 5-cylinder Volvos had a major ETM recall, and while the 2012 models use an improved design, failures still occur.

Replace the electronic throttle module. The replacement should include the updated housing and software revision. The throttle body should be cleaned before installing the new module, and the ECM should be reset to allow it to relearn idle parameters. A dealer diagnostic scan should be performed to clear all related fault codes.

The HVAC blower motor fails to operate or only works on certain speed settings. The blower motor resistor or the electronic climate control module can fail, leaving the fan stuck on high, on low, or completely off. Some owners hear a whining or squealing noise from behind the glove box before the motor fails completely.

Replace the blower motor and the blower motor resistor. The cabin air filter housing should be cleaned of debris during the repair, as leaf debris can jam the blower motor impeller and accelerate failure. On dual-zone climate models, the blend door actuator should also be inspected for clicking noise.

The Central Electronic Module (CEM), located behind the glove box, is susceptible to water damage from clogged cabin air filter drain or condensation. CEM failure causes a cascade of electrical problems: interior lights staying on, door locks malfunctioning, turn signals failing, and the vehicle randomly failing to start. This is one of the most frustrating S80 issues.

The CEM must be tested for water damage and internal circuit board corrosion. If damaged, the CEM requires replacement and programming with the Volvo VIDA diagnostic system. The AC evaporator drain line must be cleared to prevent water from reaching the CEM. A protective shield or rerouting of the drain can prevent recurrence.

The Aisin-Warner AW55-51SN automatic transmission develops harsh shifts, delayed engagement from park or reverse, and a flare between second and third gears. Solenoids within the valve body wear and develop internal leaks. A transmission fault code is stored, and the transmission may enter limp mode (stuck in third gear).

A transmission valve body rebuild or replacement resolves the shift quality issues. Solenoids can be individually replaced without removing the transmission. A complete transmission fluid and filter change should be performed during the repair. In advanced cases, the torque converter clutch may need replacement.

Volvo Cars of N.A., LLC (Volvo) is recalling certain 2008-2016 V70 and XC70, 2007-2016 S80, 2011-2018 S60 and V60, 2016-2018 S60 Cross Country, 2014-2020 S60L, 2009-2015 S80L, 2009-2016 XC60 and 2015-2018 V60 Cross Country vehicles. The flexible steel cable that connects the seat belt to the front outboard seating positions may fatigue over time, causing the seat belt to not secure the occupant in the event of a crash.

An unsecured occupant has an increased risk of injury in the event of a crash.

Volvo will notify owners, and dealers will replace the seat belt anchor cable for both front seats. The recall began December 10, 2020. Owners may contact Volvo customer service at 1-800-458-1552. Volvo's number for this recall is R10029.

VOLVO IS RECALLING CERTAIN MODEL YEAR 2011-2013 S80 VEHICLES. A SOFTWARE ERROR MAY PREVENT THE TRANSMISSION FROM DOWNSHIFTING SUCH AS SHIFTING FROM FIFTH TO FOURTH GEAR WHEN COASTING.

THIS MAY RESULT IN DECREASED ENGINE RPMS AND POSSIBLE ENGINE STALL, INCREASING THE RISK OF A CRASH.

VOLVO WILL NOTIFY OWNERS, AND DEALERS WILL UPGRADE THE SOFTWARE TO THE TRANSMISSION CONTROL MODULE, FREE OF CHARGE. THE SAFETY RECALL BEGAN ON AUGUST 10, 2012. OWNERS MAY CONTACT VOLVO CARS AT 1-800-458-1552.

VOLVO IS RECALLING CERTAIN MODEL YEAR 2011, S80, S60, XC70 AND XC60 VEHICLES. THE SOFTWARE CALIBRATION FOR THE FUEL CUT-OFF FUNCTIONALITY IN THE ENGINE CONTROL MODULE (ECM) IS TOO SENSITIVE.

SUDDEN ENGINE STALL COULD OCCUR INCREASING THE RISK OF A CRASH.

DEALERS WILL UPDATE THE ECM AND TCM WITH NEW SOFTWARE FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE DECEMBER 10, 2010. OWNERS MAY CONTACT VOLVO AT 1-800-458-1552 OR AT [email protected].

VOLVO IS RECALLING CERTAIN MODEL YEAR 2010-2011 S80, XC70, MODEL YEAR 2011 XC60 AND MODEL YEAR 2010 V70 VEHICLES. THERE MAY BE AN INTERMITTENT FAULT IN THE DRIVER'S AIRBAG CLOCKSPRING WIRING CONNECTOR FOR THE SUPPLEMENTAL RESTRAINT SYSTEM.

IN THE EVENT OF A CRASH, THE DRIVER'S FRONTAL AIRBAG MAY NOT DEPLOY AS INTENDED OR AT ALL, AND THEREFORE WILL NOT BE ABLE TO PROPERLY PROTECT THE DRIVER, INCREASING THE RISK OF INJURIES.

DEALERS WILL INSTALL A METAL SHIM IN THE DRIVER'S AIR BAG CLOCKSPRING WIRING CONNECTOR. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON OCTOBER 20, 2010. OWNERS MAY CONTACT VOLVO AT 1-800-458-1552.
