Being one of the models in BMW's 7-series line, the BMW 750il features top-notch technology and design. In fact, this series is considered to be the flagship of the BMW lineup, which will steer the company's direction in the future. Because of the model's innovative and protective features, more buyers are opting for this automobile. However, car owners should be wary of these common problems in order to prepare themselves when they encounter such defects.
One of the most common problems encountered by the luxury BMW 750il and BMW models in general involve locking of the steering wheel. This defect is primarily attributed to flimsy ignition key cylinders that wear at a faster rate than other cars' cylinders. This line of BMW models have been known to have frequent failures in the car's shift lever, which manifests in the temporary locking of the steering wheel. When left unresolved, these steering issues result to an inoperable BMW 750il. BMW manufacturers suggest the use of spray lubricants to allow the key cylinder to move more smoothly.
The BMW make of car models is known in the automotive industry for its crafty engineering. Despite this fact, the BMW 750il cars and most BMW models often encounter a failure in their head gaskets. The malfunctioning gaskets are often attributed to delicate and poorly constructed radiators, water pumps, and thermostats. When these defective parts overheat, the head gaskets are deformed and as a consequence, cause a failure in sealing. BMW recommends car owners to replace the water pump for every 60,000 miles of travel. In addition, changing the radiators at least once for 100,000 miles helps prevent blown head gasket problems for the BMW 750il.
Because most modern BMW vehicles use an electrical locking system, common door lock problems are attributed to the car's fuse box. BMW 750il owners commonly experience defects in electrical locking. In fact, a review once called the vehicle an
electrical nightmare. The errors are often attributed to the car's computer, which is the central lock module that communicates with the BMW's locks.
Yet another electrical problem, the 2001 BMW 750il's cooling system has defective fan motors that cause electrical overload and eventually causing the fans to malfunction. In fact, around 80,000 units were affected as the BMW issued a recall.
