مشاكل معروفة
Early models have iDrive malfunctions. Tyre pressure monitor may give wrong readings. Roaring sound becomes significant on runflat tyres after 20,000 kms, and some reports of low-profile ones losing pressure, but replaced under warranty. Steering rack may leak fluid out of end seal and into track-rod end gaiter. BMW claims "lifetime" automatic transmission fluid so dealer will never change blackened fluid during service intervals, so owners should get it changed independently every 80,000 kms. Battery may die overnight if the key is left in the ignition. The "check engine" light may turn on and a rattling noise heard from engine is due to leak in oil line for variable valve timing system. The oil condition sensor on the 2.5-litre engine can short out internally causing intermittent no-start conditions. Six-cylinder engines may overheat due to one or more problems with the electric water pump. Speedometer needle may vibrate at idle, fixed by reprogramming.
