# Service bulletin 511443

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10208119
- Published by NHTSA: 2022\-03\-01
- Manufacturer's number: 511443
- Manufacturer's date: 2022\-02\-16
- NHTSA component: ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE

## NHTSA's summary

The high pressure fuel pump \(HPFP\) on your vehicle may fail prematurely. A high pressure fuel pump failure may introduce internally failed component debris into the fuel system potentially causing fuel starvation. Vehicle occupants may notice a Malfunction Indicator Lamp illuminating, a fuel leak, abnormal engine noise, or a change in drive quality. Fuel starvation may result in an unexpected loss of motive power, which can increase the risk of a vehicle crash without prior warning The remedy for this condition is not currently available. We are making every effort to finalize the remedy as quickly as possible, and will service your vehicle free of charge \(parts and labor\) when the remedy is available.

## Other bulletins for the same vehicles and component

- [511903](/bulletins/11019673.md), 2025-06-20, Service bulletin: FUEL/PROPULSION SYSTEM. According to Ford Recall 24S78/24V957: "On your vehicle, it may be possible for aged biodiesel deposits to form on internal high pressure fuel pump components. This may lead to failure of the pump and may result in loss of motive power while driving. A loss of motive power increases the risk of a crash."
- [511640](/bulletins/10237174.md), 2023-07-05, Service bulletin: VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; ELECTRICAL SYSTEM. According to General Motors Recall 23V247: "These vehicles are equipped with an unused circuit that a final\-stage manufacturer may elect to use to install an optional rear HVAC system. If the final\-stage manufacturer leaves the circuit's connectors or cut wires unsealed, exposure to moisture or contamination may, over time, cause corrosion. This could result in high current draw through the circuit at the vehicles' lower left side B\-pillar. Unintended release of excessive heat from the circuit may pose a risk of a vehicle fire and increase the risk of injury."
- [511508](/bulletins/10211681.md), 2022-05-31, Service bulletin: ELECTRICAL SYSTEM. This is a Mercedes\-Benz Recall that Forest River is passing through. Forest River is not conducting any campaign separately other than notifying our owners and dealers of the Mercedes\-Benz Campaign 21V055. USA: 178 Vehicles MBAG has determined that on certain Mercedes\-Benz Sprinter vehicles, the software design of the communication module may fail to communicate the correct vehicle's location for the emergency call system \("eCall"\) in the event of a crash. Depending on the crash scenario, a temporary drop in the on\-board electrical voltage system may occur. If this occurs, the wrong location may be transmitted during an eCall. As a result, the arrival of emergency responders could be delayed, which could increase the risk of injury.
- [511379](/bulletins/10199340.md), 2021-08-03, Service bulletin: ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM. Per FCA’s Recall 21V439, the engine calibration software may not warn of low oil volume.
