NHTSA Complaint #11711949 — 2016 AIRSTREAM INTERSTATE

This complaint concerns a 2016 Airstream Interstate motorhome that has experienced multiple safety-critical failures involving the electrical system, engine starting system, fuel/propulsion system, and electrically controlled exterior components. While driving at highway speed, the exterior power awning deployed without warning or user input. The awning repeatedly extended and retracted uncontrollably, and the control switches were ineffective. I was forced to pull over on the freeway shoulder, cut electrical power to stop the motion, manually retract the awning, and secure it to prevent detachment. This created an immediate risk of collision and danger to surrounding motorists. Additional failures include complete engine non-start, generator failure, and a severe propane odor originating from the exterior propane system. The propane odor was strong enough to trigger the interior propane alarm, indicating a potential fire or explosion risk. The vehicle is now completely inoperable. The engine will not start and the ignition key will not turn. The vehicle cannot be driven and would require towing for inspection. These failures occurred progressively under normal use and were not caused by collision, misuse, or modification. This vehicle is a 2016 Airstream Interstate built on a 2015 Mercedes-Benz Sprinter chassis; the VIN corresponds to the Mercedes chassis model year.
