NHTSA Complaint #11547978 — 2020 THOR MOTOR COACH ARIA

Four times while driving, the STOP ENGINE light came on causing the vehicle to slow to 5 MPH--twice while I was on the freeway in busy traffic--very hazardous. Two different error codes showed after the check engine light came on and then after I stopped and restarted the engine a few hours later, the check engine lights turned off. I took it to a Freightliner repair dealer and the accelerator pedal was defective. I only had 9000+ miles on the vehicle. The error codes were: spn 2623 FMI: 4 oc:6 sa:0 and Spn 91: Spn: 2 oc:3 sa:0. Note: these codes totally reset as if nothing was wrong.
