Recalls to check
- Recall #09V110000Navistar is recalling certain model year my 2001-2008 workhorse W20, W21 and W22 chassis and certain model year 2009 through 2011 monaco RV admiral, arista, monarch, and riptide recreational vehicles equipped with axles that include bosch zops or zoht pin slide hydraulic disc brakes. When combined with occasional or seasonal vehicle operation may experience calipers sticking in the applied position. This can result in abnormal heat generation at the wheel end causing brake drag. The driver would normally have warning of the brake drag if undetected by the driver.
- Recall #06V225000On certain motor home and truck chassis equipped with general motors 8.1L V8 engines, improper hardening during the heat treatment process can cause the fuel rail pulse damper retainer clip to fracture, resulting in inadequate retention of the damper. If the damper becomes loose, fuel could be pumped by the fuel pump into the under hood area.

Listed groups have at least 3 complaints. The page includes the 20 largest groups plus any additional flagged groups; some complaints are not assigned to a group.
| Problem | Complaints | Share | Share ratio | Status |

| Vehicle catches fire from wiring | 3 | 3.3% | – |
AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.
