Parasitic Battery Drain

Infiniti Vehicles, mostly in Q50, QX60, and G37, often show recurring electrical faults that are next to impossible for any owners to identify. The most prominent fault is the Parasitic Battery drain, where electrical components such as sensors, infotainment systems, or control modules draw power even when the ignition is off, leading to frequent battery deaths.

Malfunctioning of the ICM & ECU

Another common problem is the malfunctioning of the Integrated Control Module (ICM), which may affect the basic features of a car, such as Power Windows, Sunroofs, or Door locks, unexpectedly.

The same problem can also arise with the Engine Control Unit (ECU). It may cause unusual behavior, such as stalling or starting.

Failure of Alternators or Voltage Regulators

Failure in alternators and voltage regulators is a common problem with these top-end segment cars. On the failure of alternators or voltage regulators, the charging system fails to maintain a proper level of battery causing battery death issues.

Wiring Harness Degradation

Wiring harness degradation is one of the most dangerous problems of electrical failure. In the extremely hot climate of Austin, TX, the exposure to heat can lead to shorts or open circuits by impacting critical systems such as lighting, sensors, or the air conditioning system of the Infiniti cars.

Faulty Sensors

Faulty sensors often create confusion in the entire electrical module. If sensors of oxygen, throttle position, and ABS wheel are found faulty, it will trigger warning lights or false signals on the instrument panel. Our team of trained technicians at Swedish Auto Service, located in the neighborhood of Austin, can only run proper diagnostics and identify such problems.
