2010 Volvo V70

The V70's inline-five and inline-six engines use a timing belt system that requires replacement at the manufacturer's specified interval. The water pump, driven by the timing belt, frequently develops leaks and is the most common failure point. A failed water pump can contaminate the timing belt with coolant, leading to belt slippage or breakage and catastrophic engine damage.

Replace the timing belt, water pump, tensioner, and all idler pulleys as a complete service kit. Volvo recommends this service at 108,000 miles or 10 years, but many specialists recommend 80,000-90,000 miles for safety. The serpentine belt and its tensioner should also be replaced during this service.

The PCV (positive crankcase ventilation) system, specifically the breather box integrated into the intake manifold, fails and creates excessive crankcase pressure. Symptoms include oil leaks from the valve cover gasket and rear main seal, rough idle, increased oil consumption, and a vacuum leak that triggers the check engine light. This is a known design weakness of the 5-cylinder engine.

Replace the PCV breather box assembly. This requires removal of the intake manifold. All vacuum hoses associated with the PCV system should be replaced at the same time. After repair, address any secondary oil leaks that developed from the excess crankcase pressure (valve cover gasket, cam seals, rear main seal).

Power window regulators fail, causing the window to drop into the door panel, move slowly, or become stuck halfway. The window switches on the driver's door panel also develop contact wear, causing intermittent operation. The rear window regulators are particularly prone to failure, and the window can drop suddenly while driving.

Replace the failed window regulator assembly. The window motor is typically replaced along with the regulator as a unit. If the driver's door master switch panel is faulty, it must be replaced as a complete assembly. The door panel clips should be carefully removed to prevent breakage during the repair.

The ABS module develops internal electronic faults from thermal stress and vibration, causing the ABS, traction control, and stability control warning lights to illuminate. Additionally, the wheel speed sensors corrode and fail, providing erratic speed readings that trigger ABS intervention at inappropriate times. Cold weather exacerbates sensor failures.

Diagnose whether the fault lies in the ABS module or the wheel speed sensors using a scan tool. Individual wheel speed sensors can be replaced affordably. If the ABS module has internal electronic damage, it can be repaired by a specialized electronics shop or replaced with a new OEM unit. Brake fluid flush is recommended during the repair.

The CEM, located behind the glove box, is vulnerable to water ingress from a clogged AC evaporator drain or windshield cowl drain. Water damage to the CEM causes widespread electrical malfunctions including failed door locks, non-functioning interior lights, windshield wiper faults, and intermittent no-start conditions. This is a common and expensive failure.

If the CEM is water-damaged, it must be replaced and programmed using the Volvo VIDA diagnostic system. The root cause — a clogged evaporator drain tube or cowl drain — must be cleared to prevent recurrence. Some specialists can repair corroded CEM circuit boards, but replacement is more reliable.

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.
