Electrical issues, particularly related to the infotainment system and battery drain, are also frequently reported. While the X3 offers a premium driving experience, potential buyers should be aware of these common problems and budget accordingly for maintenance and potential repairs. The severity of the issues ranges from minor inconveniences to potentially costly repairs, making a pre-purchase inspection by a qualified mechanic a worthwhile investment.
