BMW 540i Problems

First introduced in 1995 as a mid-size luxury sedan, BMW 540i captivated the hearts of many drivers and car enthusiasts. It was gifted with a modest 4.4-liter V8 engine, which can generate 282 horsepower and 324 lb-ft of torque. This allowed the 540i to offer a comfortable driving experience that got even more accentuated by the traditional three-pedal, six-speed manual transmission. However, great things come with some drawbacks as well. The following are the problems that BMW 540i owners commonly run into:

Engine cooling

The most common complaint against the BMW 540i is the radiator failure. A number of 540i drivers report that their radiators have cracked around the hose, causing these radiators to last for only up to 50,000 miles. The alarming scenario, though, was during the actual failure of these radiators while the car was running. A significant amount of steam appeared on the driver's front side, which obscured the view of the road. It was a very dangerous situation, which could have resulted to road accidents.

It is argued that this radiator problem roots from a manufacturing defect or poor design, but there are still no official findings as to the cause of these radiator cracks.

Electrical system

Electrical system glitches in the BMW 540i are varied. They are not exclusive to a certain part or system. These problems range from sunroof or windows that fail to close completely to serious overheating of tail light bulbs that could possibly cause fire hazard. Electrical short due to a faulty thermostat is also among the common problems included in this category, which could possibly result to further damage like melted wirings.

There was no known widespread recall to address this problem, as its nature was wide-ranging.

Power train

The power train is responsible for sending power from its source to drive mechanism, but the BMW 540i has been criticized for its automatic transmission failure. According to a number of 540i owners, the reverse gear suddenly stopped working without any indicator of wear or damage. This could have been the result of an internal slippage or damage, which eventually caused the transmission to go into neutral or safe mode.

  • BMW 540i Common Problems 22 February 2013

    Highly regarded by car enthusiasts and critics because of its excellent performance, the BMW 540i mixes luxury with power in a mid-sized sedan. Its aerodynamic, all-steel body was designed to provide protection and to increase torsion rigidity. Although these features are truly notable, there's still some chink in the BMW 540i's armor. Read on to know some of problems car owners have experienced with the BMW 540i.


    Engine cooling system

    One issue that has affected a great number of BMW 540i units was a faulty engine cooling system. The problem came from malfunctioning components of the cooling system such as the thermostat, water pump, and pump belt. This resulted to an increase in the coolant temperature and system pressure. It has also produced cracks and damage on the nearby parts that were affected.

    BMW has issued a recall of around 340,000 units that were affected. Car dealers were instructed to install a new radiator cap to control the coolant's pressure and to provide better flow in an unlikely event of an overheating engine.


    Speed control

    Another common problem encountered with the BMW 540i was its malfunctioning speed control system particularly the throttle cables. Due to strong vibrations and some environmental factors, the plastic bushing of the cables on broke, and this caused the separation of the bushing to the cable housing. This lead to failure to decelerate that's very dangerous especially if the vehicle's engaged in cruise control.

    Over 400,000 BMW 540i units were potentially affected by this problem; and BMW has instructed dealers to install a spring steel clip on the outer tube of each cable in the area of the plastic bushing. The clip was placed to prevent the dislodgment of the busing from the cable housing.


    Air bags

    The air bags on certain BMW 540i units were also problematic because they have the tendency to activate unintentionally. This was caused by the malfunctioning microprocessor in the air bag control module. The result can be a serious injury if the air bags were deployed while the driver is close to the steering wheel. Aside from that, since the air bags were activated, the battery safety terminal can also turn on that can cause the starter cable to be disconnected from the battery, and the vehicle to lose power.
