Jeep Wagoneer S · 2024–2025 · all trims

Reported symptoms

Uconnect infotainment screen freezes, reboots unexpectedly, or becomes unresponsive during driving
DC fast charging session refuses to initiate, terminates early, or sustains charge rate well below specification (Wagoneer S supports up to 200 kW (kilowatt, a unit of power) peak on 400V architecture)
Driver-assist features (Hands-Free Active Driving Assist where equipped) inactive, intermittent, or behaving inconsistently
Cluster, head-up display, or driver-information display flickering, partially blank, or showing intermittent warnings
Selec-Terrain mode behaviors (Snow, Sand, Sport, etc.) inconsistent or fail to engage as expected
Jeep app reports vehicle errors, shows feature inconsistencies, or reports vehicle as offline

Questions to ask

Pose these to the service advisor at intake. Request answers in writing or via email.

How many open recall and software campaigns currently apply to VIN (Vehicle Identification Number) [VIN]?
What software versions are currently installed on the Uconnect, BMS (Battery Management System), and other relevant modules, and which versions correspond to the closed remedies for each open campaign?
Has the Jeep dealer cross-referenced any STLA Large campaigns originally issued for the Dodge Charger Daytona EV when assessing VIN [VIN]?
Is each remedy delivered via OTA (Over-the-Air software update), dealer-side flash, or hardware adjustment?
Will all open campaigns be addressed in a single visit, or are sequential visits required?
Does the Jeep dealer service center handling VIN [VIN] have BEV-specific diagnostic equipment and technician training current as of the visit date?

Documents to request

Each item should be received in writing before authorizing repair work.

Diagnostic report listing all stored, pending, and historical fault codes from the affected modules
Repair order with technician notes, including a list of every recall and campaign reference number addressed during the visit, with cross-platform STLA Large references explicitly noted
Written confirmation of software versions installed before and after the visit on each affected module
Written confirmation of which campaigns are now closed for VIN [VIN] following the visit
Written confirmation of the technician's BEV-specific certification or training, if applicable to the work performed

Pre-service evidence

Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.

Screenshot or video-record any Uconnect, display, charging, or driver-assist defects at the time they occur
Note specific incidents — system reboots, charging failures, ambient conditions — with dates
Save all Stellantis correspondence regarding software updates, recalls, or feature delivery timelines
Screenshot the Jeep app status pages over time, showing any reported errors
Save records from third-party charging network apps showing failed session details
Note odometer reading at drop-off and at pickup

Service advisor interaction

Operational notes specific to the conversation at the service desk.

Record the full name of the service advisor and the technician performing the work
The Wagoneer S is the first BEV in Jeep's US lineup; some service centers may have limited prior BEV-specific experience. Confirm in writing that the technician assigned to high-voltage work has appropriate certification.
STLA Large is shared with the Dodge Charger Daytona EV across Stellantis brands. Cross-platform campaign coverage may apply, but the Jeep dealer system requires active cross-referencing for these campaigns
Multi-campaign software situations are particularly susceptible to incomplete documentation. A general 'software updated' note without enumerated campaign references creates ambiguity about which specific campaigns are closed.

Repair authorization

Cautions before signing.

Recall and software campaign work is performed at no charge to the owner; do not authorize any charge for parts or labor associated with these campaigns
If a diagnostic fee is presented, request written confirmation of whether the fee is refundable if the issue is later determined to be recall- or campaign-covered
If high-voltage component replacement is quoted, request written warranty classification before signing the repair authorization
Repair authorization signatures often include language permitting additional related work — read the document and decline blanket additional work in advance

Post-service verification

Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.

Verify the Uconnect system functions normally without unexpected freezes or reboots during a short test drive
Conduct a verified DC fast charging session at a CCS-compatible fast charger before traveling more than a short distance from the dealership
Test driver-assist features to confirm correct operation
Test Selec-Terrain mode engagement and behavior across modes, if applicable to the service
Confirm no warning messages or system errors on the cluster after a full ignition cycle
Verify the Jeep app reflects accurate vehicle status with no reported errors

Warranty notes

Stellantis has issued recalls and service campaigns affecting the Wagoneer S during the early production period. The applicable campaigns for VIN [VIN] should be checked at every service visit, including any cross-platform STLA Large campaigns originating with the Dodge Charger Daytona EV.
Wagoneer S components are covered under Jeep's New Vehicle Limited Warranty and the high-voltage battery component warranty (8 years / 100,000 miles in most US markets). Coverage period and conditions should be confirmed in writing.
Recall remedies are performed at no charge to the owner regardless of vehicle age, mileage, or warranty status. A recall remains open until performed.
Repairs performed under goodwill rather than warranty or recall do not extend the warranty period. Confirm in writing which classification applies.

Observational patterns

The Jeep Wagoneer S is the first BEV in Jeep's US lineup, built on Stellantis' STLA Large platform shared with the Dodge Charger Daytona EV. Cross-platform campaign coverage depends on the Jeep dealer system actively cross-referencing Dodge-issued service bulletins.

Jeep dealer service experience with battery electric vehicles is newer than for plug-in hybrid (4xe) or internal combustion vehicles. Service quality and BEV-specific diagnostic capability varies between dealer locations during this transition period.

The Wagoneer S is positioned as a luxury wagon rather than a Trail Rated Jeep. Service interactions can carry assumptions from Jeep's traditional off-road heritage that do not match the Wagoneer S's actual positioning. Owner-side awareness of the positioning distinction is operationally relevant.

OTA delivery does not always produce a corresponding entry in the dealer-side service record. The closure of a recall delivered over the air requires explicit documentation through the dealer system.
