This car uses the problematic BMW N47 engine, which has a poor record for reliability.
Most issues envelop the timing chain, which is at the rear of the engine instead of at the front. The tensioners are prone to wearing and wrecking the engine. Personally, I'd steer clear of any BMW with the N47 engine.
