Coach and Equipment Mfg. Corp. has determined that a defect, which relates to motor vehicle safety exists in your Coach and Equipment Mfg.

Corp. bus installed with a Roush CleanTech Gen 4 or Gen 5 LPG fuel system is being recalled. WHAT IS BEING RECALLED: This recall applies to approximately 353 Coach and Equipment Mfg. Corp. Phoenix buses installed with a Roush CleanTech Gen 4 or Gen 5 LPG fuel system manufactured between January 1, 2016, and March 31, 2023 and operated in the Salt Belt states. WHY IS IT BEING RECALLED: Roush CleanTech has determined that the zinc plated carbon steel fitting on the fuel return line in its Gen 4 and Gen 5 LPG fuel systems may corrode over time due to exposure to salt spray, particularly where impacts from road debris have damaged the protective coating that had been applied to the fitting.

CLEAN TECH 0EcE,vEn n AUG O 1 21122 U BV=——- SAFETY DEFECT NOTIFICATION TO PURCHASERS OF ORIGINAL EQUIPMENT Mr. George D’ Amato Quality Manager Coach & Equipment 130 Horizon Park Dr. Penn Van, NY 14527 Re: Determination That a Safety-Related Defect Exists in the Fuel Return Line in Certain ROUSH CleanTech Gen 4 and Gen 5 LPG Fuel Systems Dear Mr. D’Amato: I am writing to formally notify you that Roush Clean Tech (“ROUSH”) has determined that the zinc plated carbon steel fitting on the fuel return line in its Gen 4 and Gen 5 LPG fuel systems (“LPG systems”] may corrode over time due to exposure to salt spray, particularly where impacts from road debris have damaged the protective coating that had been applied to the fitting. Such corrosion could lead to a failure ofthe fuel return line fitting, which would result in a leak of liquid propane fuel, which would create the risk of a fire. On June 9, 2022, the National Highway Traffic Safety Administration (“NHTSA”) accepted ROUSH’s defect information report notifying NHTSA of Roush’s determination that a defect relating to motor vehicle safety exists on some of its LPG systems due to this potential corrosion concern. However, because the corrosion at issue here occurs only in the presence of significant amounts of road salt, ROUSH’s defect determination applies only to LPG systems installed on vehicles originally or currently registered in the following states: Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, and Wisconsin. As required by NHTSA’s regulations, in its defect information report, ROUSH identified your company as a purchaser of some of the defective LPG systems for use as original equipment in new, altered vehicles. As such, NHTSA may contact your company to request that it recall vehicles with those systems that are or were registered in the States identified above. ROUSH CleanTech I 12170 Globe St. I Livonia, Ml 48150 800.59.ROUSH ROUSHcleantech.com …. ROUSHe CLEAN TECH If your company decides to conduct such a recall, ROUSH will provide remedy parts and labor at no cost to you or your customers. Unfortunately, however, despite ROUSH’s best efforts, replacement parts are not currently available. As soon as those parts are available, we will let you know via a second notice. If you currently have any of ROUSH’s LPG systems in your inventory with fuel return lines that have not been repaired or replaced, you should not use them on any vehicles. Similarly, you should not sell or deliver any vehicles that are equipped with defective fuel return lines that have not been repaired or replaced, since that would be a violation of Federal law. If you have any questions regarding this matter, please call me at (734) 466-6738 or at mario.genovese@roush.com. Sincerely, Mario Genovese Director of Customer Success ROUSH CleanTech I 12170 Globe St. I Livonia, Ml 48150 800.59.ROUSH ROUSHcleantech.com
