$7155 quote to replace 2 electrical harnesses. Reason: "warning: srs airbag check. Take vehicle to dealer". The junction box is hidden behind the driver side front panel. The pins in the junction box belonging to the airbag wiring harness (part # 82141-48r51) that runs underneath the dashboard were fried due to electrical short (unexplained). Because the junction box also brings the rear wiring harness (part # 82162-48d40 ) to tail, headliner, and back of the vehicle, this must be replaced as well. I fear that there is a major flaw in the electrical system / srs airbags of this vehicle and the vehicle electrical system has experienced premature failure.
