Electrical System

ODI #11452979

Incident: April 12, 2019 · Filed: February 19, 2022

1. Problem: main power (connect) switch doesn’t communicate It shows there is power to the coach but IT DOES NOT SHOW whether or not the main power is connected to the chassis (motor) battery. I have been stranded with a dead chassis battery because of Thor’s neglect to use a communicative power switch. Safety issue because one could be camping in an area without emergency start services because of this. 1. Thor is aware these improper power switches in the 2018 (and in other model years) are non communicative and can leave people stranded. Thor has admitted the 2018 switch is wrong and corrected the switch in the2022 models (I confirmed this at the dealer). They have admitted fault. 3. If owners of 2018 Vegas Models (and other model years using the uncommunicative switch as ours) can be left stranded - that’s risky and a safety issue. Thor tried to replace my power switch but found it too difficult (and possibly potentially more costly) and, as such, abandoned the replacement. One moment I was delighted about their concern for my safety and we’re replacing it, and then I was told they were abandoning the replacement because they deemed it too hard). Can you believe Thor doing such a thing? The dealer has confirmed this is risky and a safety issue. I now have an RV I’m scared to use feeling it may not start because the switch doesn’t communicate connection to the chassis. This totally unacceptable
