Cause of Malfunction

The cause of the brake control system malfunction in the 2016 Infiniti QX80 has been attributed to a variety of factors. One primary factor is that the relay switch in the control module was improperly placed and thus caused a short circuit.

How Malfunction Affected Consumers

The malfunction in the brake control system had a severe impact on consumers who owned or leased this vehicle. In some cases, these malfunctions led to an increased risk of accidents due to slow reaction times when applying brakes or excessive braking force when decelerating. Additionally, some consumers reported experiencing financial losses due to repair costs associated with these malfunctions.

Recalls and Repairs

In response to these complaints, Infiniti issued a recall for all affected vehicles in order to address this issue and prevent future malfunctions from occurring. As part of this recall, Infiniti replaced the faulty relay switch and provided updated software for the brake control systems in order to correct any existing malfunctions. Additionally, they extended their warranties for affected vehicles so that future repairs would be covered under warranty if needed.

Preventative Measures

In order to prevent similar problems from occurring in future vehicles released by Infiniti or other automakers, it is important that automakers take preventative measures before releasing vehicles into production. This includes ensuring that all components are properly placed and tested before being installed in vehicles, as well as performing rigorous testing on vehicles after they have been manufactured in order to identify any potential issues before they become problems for consumers. Additionally, automakers should also ensure that their warranties cover any issues related to faulty components so that consumers are not left paying out-of-pocket for repairs due to malfunctions caused by faulty parts or improper installation procedures.
