What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Thor Motor Coach Vegas, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Driver side wiper sweep angle does not fully clear the field of view.
DIRVER'S SIDE WINDSHIELD WIPER DOES NOT CLEAR THE DRIVER'S FIELD OF VIEW. THE WIPER STOPS AT ABOUT THE 1 O'CLOCK POSITION LEAVING A LARGE PORTION OF THE WINDSHIELD OBSCURED. THOR MOTOR COACH HAS BEEN CONTACTED ON THIS MATTER BUT HAS YET TO PROVIDE A REASONABLE FIX OR REPLY.

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

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
