T8 owners: check the battery recall
Campaign R10312, from April 2025, says the T8 plug-in hybrid's high-voltage battery may overheat and cause a fire. Check your VIN at vehiclerecalls.gov.au today, and follow what the recall notice tells you to do.
When is a Volvo XC90 timing belt replacement due?
On the 2003 to 2012 XC90, CarsGuide says cam timing belts need changing at 10 years or 150,000 km, so ask for proof it's been done. A car that old should be well past its first change. The 3.2 six-cylinder is the exception, with chain-driven camshafts.
On the 2015-on car, the D5, T6 and T8 four-cylinders use a belt at the front of the engine to drive the exhaust camshaft, and gears to drive the intake camshaft. Don't apply the older car's figure to these engines. The change point is in the schedule for your car, so ask the mechanic to show it to you.
What should you watch on an older XC90?
- Low oil warnings, white exhaust smoke or a rough idle on a 2007 to 2011 3.2. Volvo's Technical Journal 24643 covers excess oil use on engines built before 4 May 2011.
- A noise from the engine on a V8. Water trapped between the cylinder banks can corrode the balance shaft bearing, and Volvo advises against pressure washing. Drain holes and a better bearing came in from engine no. 6833.
- A fuel smell on a 2003 to 2005 petrol. The fuel pump flange may crack in hot climates, which is worth checking in an Australian summer.
- Heavy steering on a 2007 to 2010 D5. Three recalls cover a power steering hose that can rub the cooling fan and suddenly cut the assist.
- A flat battery overnight. The infotainment system can stop a control module going to sleep.
What goes wrong on a 2015-on XC90?
The one fault on Australian Car Reviews' list is an oil leak from a plug in the VVT pulley (part of the variable valve timing) on 2016 T6 and T8 cars. You'd see a low oil level warning, and the fix replaces the two plugs.
The recalls run longer. Campaigns R29939 and R29945 cover an intake manifold that may melt or deform, and R29936 a coolant bleeder hose that may crack near the catalytic converter. R10100 covers a fuel pump fuse that can cause stalls, R10259 a second-row seatbelt buckle and anchor screw, and R10289 a brake pedal rod. The site itself says the count isn't a measure of reliability, but on a car this complex it pays to check every one.
What moves XC90 maintenance?
Weight, mostly. CarsGuide says that because the XC90 is heavy, you should expect to replace tyres and brakes more often, and that pulsing through the brake pedal can mean the rotors need replacing. Age matters on older cars, where a belt, a steering part and an oil check can land together. A T8 adds hybrid checks.
The current XC90 is on 12 months or 15,000 km, whichever occurs first. It has a five-year, unlimited-kilometre warranty, and plug-in versions get eight years or 160,000 km on the high-voltage battery. If a qualified independent mechanic follows Volvo's schedule and specifications, that does not by itself void the warranty. For cars made from 2002 on, an independent mechanic can buy the same service and repair information a Volvo dealer can.

Our take on an XC90
Split the car's needs into three lists: recalls (Volvo's to do), overdue items like the timing belt, and everything else. We'd start with the VIN check, then ask a mechanic who works on Volvos to go through the service record against the schedule. On an older car, ask for proof of the last belt change before you spend anything else, and have a used one inspected before you buy.
