Tail Light Switch problem #1

The contact owns a 2011 Suzuki Sx4 awd (na). While driving approximately 65 mph, the contact attempted to turn on the high beams and the noticed the head lights had not been turned on. The contact stated the daytime running lights were illuminated and were bright and he thought the head light were on. The instrument panel lights were illuminated which the contact stated usually indicated the tail lights are on. The contact went through the manual and stated it did not see information regarding the instrument panel illuminating without the headlight being illuminated. The dealer was contacted and stated that was the design of the vehicle. The manufacturer was contacted but because the contact was recording the call they could not speak with him. The approximate current mileage was 1,600.

Exterior Lighting problem #2

Constant humming from the rear hatch lock actuator -- and the rear hatch partially unlocks and unlatches itself while the car is in motion. The power locking system is malfunctioning completely. The daytime running lights and automatic indoor dome light also stopped working. I replaced the rear hatch lock actuator with a brand new Suzuki part, but determined this is not the cause of the problem. Per the attached pdfs of online repair forum posts, apparently all of these issues are part of a circuit that normally is activated when one releases the parking brake. According to those who investigated the problem in some depth (see the attached pdfs), a short in this circuit ends up causing one of the terminals in the body control module ("bcm") to burn out. This is a safety issue because (I) it is dangerous to have the rear hatch release and/or fly open while driving, and (ii) the daytime running lights also are disabled by this electrical failure. I made Suzuki aware of this problem in December 2018 and again today. The problem likely entails a repair cost greater than $1,000, but Suzuki is unwilling to take any action.
