Airstream Interstate Problems by year

Vehicle then re-entered limp mode with no codes stored. Further diagnosis found the DPF clogged/broken, requiring full replacement. Prior to this trip, the same vehicle's EGR valve had already been cleaned twice and eventually replaced with the EGR cooler. Mercedes-Benz has separately extended the EGR valve warranty on this model range to 15 yrs/150,000 miles, indicating a known reliability issue. EGR problems are mechanically linked to DPF soot loading, and may have contributed to this DPF failure. All failures (EGR, DEF nozzle, DPF) occurred at approximately 72,815 miles - well under 100,000 miles and well short of the manufacturer's stated ~150,000-mile design life for these components. Filing to document a pattern of premature emissions-system failures on this platform and the real safety hazard created when the vehicle was forced into a dangerously slow, uncontrolled speed on a high-traffic mountain highway grade. It appears both the Diesel Particulate Filter, Injector Nozzle were the main failure points of this emission system. It should have at least a 10 year, 100,000 mile warranty (not 5yr, 100,000)!

before. Under the Dieselgate emission modification (per the 2021 Daimler/EPA/CARB settlement), the DEF/SCR system components got even more explicit extended coverage, since the settlement warranty language specifically calls out the SCR catalyst and related dosing components for extended protection beyond the base warranty. This component is failing on a regular basis and should be added to the recall regardless of whether it had the diesel gate modification.

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.

that all need to be addressed. For some unknown reason a jumper wire had been installed between the chassis batteries and the coach batteries. I can only assume this was used to trick the inverter into charging even when the coach batteries were low. This wire needs to be removed. Incorrect batteries. The unit has 2 wet cell batteries, these need to be AGMs, this is a health and fire hazard. The inverter charger is only outputting12VDC at 7A, even though it is rated for 50A. The internal fan makes a clicking/rubbing sounds when it turns on, the inverter needs to be replaced. It is a Magnum MMS1012. The battery disconnect is not working remotely, I have verified the switch wiring and continuity. The disconnect is faulty, AS P# 512604. Also, it was later discovered that the macerator mounting bolts are badly rusted to a point they will not come off without breaking and they are also welded to the mounting bracket. Upon review of my paperwork, photos & videos taken during the test drive, I discovered that the vehicle that I test drove was actually a 2015 Sprinter and not the 2014, that they sold to me. The dealership deliberately switched the vehicle without telling me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

system in the 2019 model year (presumably to remedy this safety risk). The risk is much greater in the airstream vehicles, however, because 1) the magnum mms1012 is (improperly) mounted on a flammable wood board in a flammable wood box, and 2) the mms1012 is mounted directly underneath the sleeping area of the rv inside the cabin. It appears airstream became aware of this risk more than a year ago, because airstream changed the design of the rv electrical system in the 2019 model year, presumably to remedy the risk. Airstream has not issued a service bulletin or recall yet to apply the remedy to older model years (2014-2018). Since the risk is already identified as described in 17v-704, I think the nhtsa should expand the recall to include all airstream interstate rvs from 2014 to 2018, because airstream appears unwilling to take remedial action on their own.
