Incorrect plastic specification for the Ingenium I6 3.0L petrol oil filter housing. The housing can crack and spray engine oil onto hot components. Fire risk. Recall N908.

Symptoms: Visible oil leak, oil puddles, oil warning light, in severe cases smoke or fire

The PT306 inline-six shows timing chain wear with rattling on cold start. Although more robust than the 2.0L four-cylinder, wear and tensioner issues are documented at higher mileages.

Symptoms: Metallic rattling on cold start, rough idle, engine warning light with camshaft correlation errors

PT306 turbochargers develop bearing wear and oil blow-by particularly with insufficient oil change intervals. Allow cool-down time after spirited driving.

Symptoms: Whistling or howling noise, smoke from exhaust, power loss, elevated oil consumption

The PT306 water pump and thermostat are known wear items. Failure leads either to persistent undercooling or dangerous overheating.

Symptoms: Temperature fluctuations, coolant loss, steam from bonnet, overheating warning

The turbocharged PT306 inline-six shows elevated oil consumption at higher mileages, especially under hard use. Causes: turbocharger shaft seal wear and short-trip degradation.

Symptoms: Regular top-ups required, faint blue smoke under acceleration

On the 48V mild hybrid system, the DC-DC converter from 48V to 12V fails. Without a working converter the 12V battery is not charged — complete vehicle shutdown is possible.

Symptoms: Charging system fault warning, red battery symbol, infotainment shutdown

Air springs tear and the compressor overloads. Typical case: vehicle drops after parking, compressor and both air springs plus valve block replaced (approx. 2,200 euros). Occurs regularly despite the aluminium body.

Panoramic roof drain hoses corrode at the plastic connector fitting and break off. Water runs through the body to the audio amplifier under the driver's seat. Several vehicles written off. Annual cleaning of the drains strongly recommended.

Water ingress through failed sunroof drains or leaking windows damages control units under the front seats. Multiple ECUs affected simultaneously. Audio amplifier under the driver's seat particularly vulnerable. Total losses documented by insurance in confirmed cases.

Tailgate seal and gaskets around the rear lights leak — water collects in the spare wheel well. Water runs out when opening the tailgate after rain. Seals and light strip sealing must be replaced.

Rear brake calipers seize due to corrosion of the guide pins in the aluminium housing. Vehicle pulls to one side under braking. Regular replacement necessary. Disc life reduced to approximately 50,000 km by the binding effect.

ZF 8HP gearbox suffers harsh shifts, delayed engagement and torque converter issues when oil changes are skipped. Gearbox oil change recommended every 60,000 km. Sensor fails to detect park position. Diesel variants particularly affected.
