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 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
- How many open recall and software campaigns currently apply to VIN [VIN]?
- Has the Jeep dealer cross-referenced any STLA Large campaigns originally issued for the Dodge Charger Daytona EV when assessing VIN [VIN]?
- 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
- 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
Pre-service evidence
- 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
Service advisor interaction
- 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
- 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
- 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
Email templates
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.
