general problems of the 2015 Toyota Tacoma

Trac off & engine lights came on. Removed gas cap and put it back on. Removed cables to the battery and left them off. Replaced battery cables. Lights remain on. Went to dealership and they charged $100 to scan vehicle. They don't know what's wrong and said it'd be another $800 to check further. They said maybe a rodent had chewed through a cable??? have seen several reports of this vehicle condition and the battery cable resetting took care of the problem a lot of the time. Not this time. Don't feel comfortable a. Driving the truck with these lights on and b. Don't feel comfortable with handing over $800 for them to look into it. What to do?????????????.

Rodents ate through the soy based wire insulation in engine compartment.

My truck was recently damaged from rodents,they built a nest by engine and chewed wires. After further research I found that auto manufacturers in order to go green are using soy based products on wires instead of petroleum. They are using sugar in there plastics. Rice husks in there interiors. All this stuff attracts rodents. This is unacceptable! my dealership said they are seeing at least 2 rodent damaged vehicles a week. My truck is driven daily and sits no longer than 8 hours. The total damage on a brand new truck with extended warranty was 2700 out of pocket, this damage was no covered by warranty.

Water leaking into passenger compartment - soaking electrical wire bundle, seat and floor; dripped at right passenger seat grab handle in rain or wet snow vehicle stationary or moving.
