Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €14,500, which isn't a realistic scenario but is a useful ceiling.
All issues, by system
Engine
Coolant vanishing without a visible leak, temperature rising under load, and eventually overheating and white smoke. The same head distortion as the Toyota 2.2, on the higher-output version fitted to the IS. Lexus and Toyota extended warranty coverage in several markets, so documented head work is the thing that decides the car.
Check: Ask for head or warranty paperwork first, then check the coolant level and the expansion tank for residue. Unexplained top-ups should be treated as the fault.
Later parts: Revised cylinder head fitted under warranty programmes and in later production
Emissions
Warning light, limp mode, oil level rising above the maximum mark from fuel dilution. The filter needs sustained hot running to regenerate. A car used for short urban trips never completes a regeneration cycle.
Check: Read the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.
Coolant loss with no visible external leak, white smoke, sweet smell. The EGR cooler cracks internally and leaks coolant into the intake. BMW recalled affected diesels over a fire risk from glycol deposits igniting.
Check: Check coolant level and look for unexplained top-ups in the service history. Verify the recall was carried out. It's free and searchable by VIN.
Suspension
Knocking over bad surfaces, vague or wandering steering, uneven front tyre wear, steering shimmy under braking. The front lower arm bushings are a known wear item on this chassis and go well before the ball joints.
Check: Drive over a rough road at low speed with the windows down and listen. Check the inside edges of the front tyres for feathering.
Harsh ride, vibration at speed, slow punctures. Stiff-sidewall run-flats transmit impacts straight into the rim, and these alloys crack rather than bend.
Check: Inspect the inner rim edge of every wheel for cracks and hairline splits, not just the face for kerbing. Budget for a set of conventional tyres; most owners switch and the ride improves markedly.
Knock from the rear over speed bumps, a hollow thump from the boot area. The rubber mounts perish. On hard-used cars the mount can crack the surrounding turret metal, which is a far bigger job.
Check: Lift the boot floor and look at the top of the shock towers for cracking or a lifted mount. Listen for a knock over bumps.
Body & corrosion
Bubbling at the rear arch lip, scaling on subframe mounting points and rear suspension components. Age plus road salt. This generation isn't a notorious rotter, but nothing from 2005–2013 is immune in a salted market.
Check: Put it on a lift and look at the rear subframe mounting points and the arch lips from behind. Largely a non-issue on cars from southern Europe, a real one on northern and Baltic cars.
Electrical
Headlights, indicators, windows, wipers and central locking stop working at once, usually right after a battery change or a jump start. The module's memory corrupts when supply voltage dips. It is the single most common electrical failure on this generation.
Check: Test every window, both mirrors, the wipers, all exterior lights and the central locking before you drive. If any cluster of these is dead, this is why.
Black screen, rebooting, refusal to read the drive, non-functioning navigation. The early CCC unit's hard drive and mainboard fail with age. Later CIC units are more reliable.
Check: Turn it on and use it for a few minutes: navigation, radio, settings. Reboots during that window are the fault showing itself.
Random electrical faults, warning lights that come and go, a battery that dies again within a year. The car's power management must be told a new battery was fitted. Cheap replacements are routinely fitted without coding, which then overcharges or undercharges the new battery.
Check: Ask when the battery was changed and whether it was registered. A car with a new battery, no registration and a scatter of odd electrical faults usually just needs coding.
Drivetrain
Grinding or binding at low-speed full lock, 4x4 warning lights, a shudder when manoeuvring. The actuator motor and the transfer case's internal chain wear, especially on cars run with mismatched tyre sizes.
Check: Full-lock circles in both directions in a car park, slowly, listening for binding. Check all four tyres are the same brand and wear, mismatched tyres destroy these.
Cooling
Coolant smell after a drive, slow unexplained loss of coolant, crusty residue around the tank seams. The plastic tank goes brittle with age and splits, usually at a seam or around the level sensor.
Check: Look at the tank with the engine warm, dried coolant leaves a white or pink crust. Cheap to fix, but it tells you how the car has been maintained.
How to read this
Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an 2AD-FHV problem from an E9x problem.
Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
