2013 Toyota Sequoia Electrical Problems

Your dashboard safety lights keep turning on and off without any clear reason, particularly the airbag warning light and messages for traction control, check engine, and 4-wheel low. You've also noticed that the engine cranks for an extended period before starting and produces an excessive fuel smell. The dealer has made seven repair attempts over nearly three years but hasn't been able to permanently fix the problem, as the lights continue to come on during highway trips. The underlying issue appears to be electrical shorts in the airbag system and engine controls that require comprehensive electrical diagnostics and potential replacement of the airbag control module or related wiring.
