OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-221 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Prevost Car (US) Inc. Submission Date : DEC 22, 2022 NHTSA Recall No. : 22V-221 Manufacturer Recall No. : SR22-05 Manufacturer Information : Manufacturer Name : Prevost Car (US) Inc. Address : 201 South Avenue South Plains NJ 07080 Company phone : 908-222-7211 Population : Number of potentially involved : 5,143 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2010-2023 Prevost H3-45; X3-45; X3-45 Com; H3-45 VIP: X3-45 VIP Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : DIESEL Descriptive Information : Components causing this defect have been installed on production for MY2015 and after. However, these components have been installed on after market to vehicles manufactured before MY2015 so, Prevost has considered that affected population is all vehicles produced from 2010, the year of introduction of Volvo Engine. Production Dates : JAN 01, 2010 – APR 04, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : A small percentage of Prevost units have experienced thermal events upon failure of alternator front bearing because the robust alternator belts continues to turn the alternator bearing even after the failure. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In some cases, when alternator’s front bearing fails, it could overheats causing a local thermal event. Description of the Cause : New and more resistant belts were installed on MY2015 and later vehicles. With this new type of belts, in event of alternator front bearing seize, belt may continue to drive the alternator causing abnormal friction for a longer period of time than the old ones. Identification of Any Warning that can Occur : Noise coming from alternator front bearing and, maybe, alternator not charging telltale light.

Production Dates : JAN 01, 2010 – APR 04, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : A small percentage of Prevost units have experienced thermal events upon failure of alternator front bearing because the robust alternator belts continues to turn the alternator bearing even after the failure. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In some cases, when alternator’s front bearing fails, it could overheats causing a local thermal event. Description of the Cause : New and more resistant belts were installed on MY2015 and later vehicles. With this new type of belts, in event of alternator front bearing seize, belt may continue to drive the alternator causing abnormal friction for a longer period of time than the old ones. Identification of Any Warning that can Occur : Noise coming from alternator front bearing and, maybe, alternator not charging telltale light.

Address : 7900 National Service Rd. Greensboro North Carolina 27409 Country : United States Chronology : -2019-03-24 First Case reported -2021-04-23 First analysis on alternator front bearing failure. No evidence was found to consider this failure as a safety related issue. -2021-05-18 NHTSA-ODI opened a preliminary evaluation (PE21-011) related to alternator front bearing failure and AFSS activation. -2021-07-23 Prevost sent the package of information required by ODI -2022-01- ODI came back to Prevost with a new set of questions -2022-02-28 Prevost sent a package to answer the ODI -2022-03-09 NHTSA and Prevost met to discuss ODI findings. ODI defined that even with the low percentage of failure on alternators because of front bearing failure, there could be a safety related defect related to front bearing failure -2022-03-15 Internal inquiry was started to analyze root cause. A link between the introduction of new belts and an increase of thermal events related to alternator’ front bearing failure was identified. This new information triggered a new new case to present to Volvo Product Safety Committee (PSC) -2022-03-30 Case presented to PSC. PSC decided there is a safety related defect and a recall is required -2022-03-31 Preliminary discussion with NHTSA to expose the findings -2022-04-06 Prevost submitted the vehicle defect report to NHTSA Part 573 Safety Recall Report 22V-221 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Prevost will change the defective belts for polyester belts.
