Following Jayco and Entegra instructions, I delivered my coach to Blue Compass RV. It has now been more than SIX MONTHS out of service. Jayco Pre-Authorization has denied the required battery replacement and referred me to the battery manufacturer, even though Entegra bulletins and recall procedures identify and correct the conditions that caused the damage. Completed Recall and TSB Work Approved by Entegra and Jayco · 22-075 (TSB) A/C Electrical Connection Instructions, September 2022. Replaces WAGO connectors. · 22-076 (TSB) Firefly Terminator G4 Tap Connector, September 2022. Corrects communication errors within the lithium battery network. · 23-101 (TSB) Front Spotlight Electrical Update, April 2023, revised September 2023. Mitigates spotlight over current that can affect Firefly. Adds harness, relay, and software. · 23-120 (TSB) Renogy Inverter Settings, November 2023. Updates parameters; requires Battery Type = LF16 and custom set points. · 23-123 (TSB) Alternator Fuse Replacement, December 2023. Replaces 300 A MRBF with 200 A MRBF. Confirms alternator charging 30 to 100 A on Samkoon. · 24-015 (TSB) Renogy Battery Firmware Update, September 2024. Updates BMS to v137.4.5 to address alternator not charging the battery. Includes state-of-charge calibration. · 24V-160 / 2024-141 (Recall) Renogy Lithium Battery Firmware Update, May 2024, revised August 2024. Recall firmware to v137.4.4. Inspection identifies stuck contactors and requires battery replacement when found. Service bulletins 23-120, 23-123, and 24-015 show that the system ran with outdated inverter and alternator settings, an oversized alternator fuse, and battery firmware that interfered with proper charging. These factors accelerate cell imbalance and degradation. Only after Entegra-approved updates were applied did the full extent of battery degradation become evident. Replacing the battery earlier would have risked repeat failure.
I had the same issues as identified in a current recall entitled: Model 907 Sprinter. Model Year 2019-2022 Update Instrument Cluster Software. In my case the instrument cluster remained non-functional upon vehicle start-up exactly like the recall with an added problem of the ignition push button would not shut off the vehicle. I was left with a vehicle I could not shut off without an operational instrument cluster. While my model year and model number match this recall, for some reason my VIN number was not included in the recall so the dealer will not upgrade the software and fix this problem. The scope of this recall must be corrected to include my VIN number.

Error Message: "Service Required: Do Not Shift Gears, Visit Dealer" The 2021 Sprinter Van indeed would not shift gears and I was stranded. I was finally able to be towed two days later to a Mercedes Benz dealership. The technician noted corrosion in the EIS unit and replaced. It appears to be a known problem with Sprinter vans with bulletin from Mercedes[XXX] due to condensation getting into this vital area.

This vehicle has factory installed swivel seats. When we were parked, we swiveled the seats around to use the table and then back prior to driving again. When we tried to move the seat closer to the steering wheel, the electric seats did nothing and upon inspection, realized the fuse had blown for the power seats. We replace the fuse and drove a little ways and swiveled the seat again to test it and this time the seat binded up on something. Upon further inspection, we noted several bare wires caught up in the swivel mechanism underneath the driver side seat. When we tried to start the car again the windshield wipers were going off on their own , the airbag sensors were lit and nothing seem to be working quite right. The vehicle was shut off and again found several wires that were bare and were touching and found additional blown fuses. After investigating online to see if there was an open recall for this vehicle, we found that the 2019 2020 and 2021 sprinter vans had a very similar issue with the wiring under the swivel seat that caused airbag deployment. I have only had this vehicle for five days and it is now at the dealer. The dealer told me it could possibly be a six-month wait if they have to replace the vehicle wiring harness and we were informed by the 800MB number that there were no open recalls for this specific vehicle. I don’t understand how this could not be part of an open recall if it was previously reported in the 2019 2020 and 2021 models with swivel seats, and mine is a 2021.
