6th Gen Electrical Issues in Cold and Wet Weather

[Hoserhound]

Brand new '25 4Runner TRD Offroad Premium has had consistent issues when its cold or wet outside. Today a right turn signal turned on the wiper blades and showed an error on hood being open. Previously have lost temp gauge, fuel gauge showed full for a couple weeks, lost RPM view and couldnt control wipers. Also something with back hatch not wanting to open through these issues. At 5k mile check up the dealer said they couldnt find any error codes and basically wrote it off as completely fine. Any ideas or suggestions for help would be appreciated!

12volt battery health needs to be determined
similar issues happen to other toyota hybrids when 12v battery is not up to snuff

other than that, time to check grounds and all
wiring to the multiple fuse and relay boxes

Thank you. We've gone through the battery check. I would have hoped the dealer would check the grounds and wiring. I'll go back through and try that again. Appreciate the input.

I would definitely take a look at the 12v. If you have a volt meter that would be a no regrets place to start .
