Some BMW X5 owners report experiencing sudden engine shutdowns while driving, accompanied by a lack of dash power and failure to crank. These issues may stem from low fuel pressure, dirty or defective fuel injectors, or a malfunctioning fuel pump. Additionally, problems with the alternator, battery, or fuses could lead to the vehicle stopping unexpectedly and not restarting. Concerns regarding fuel quality, supply, or injectors might also contribute to stalling. Furthermore, a weak or failing battery, a faulty alternator, or malfunctioning sensors such as the crankshaft or camshaft position sensors can result in engine shutdowns. Lastly, a faulty Engine Check Unit may cause the vehicle to shut off due to factors like water in the fuel, bad spark plugs, or a clogged air filter. Owners experiencing these symptoms are advised to consult a qualified mechanic for a thorough inspection and resolution of the issue.
