What's wrong?
Auto-P is the automatic parking function on the Sprinter chassis used under these 2020-2021 Dynamax recreational vehicles, including Isata, Sunseeker, Battisti, Prism, Galleria, and Forester models. The feature is meant to help place the automatic transmission in park under specific conditions, such as when the driver leaves the seat or unbuckles. The owner's manual is supposed to tell the driver exactly when that function works.
On affected vehicles, the manual gives the wrong description of the conditions that trigger Auto-P. A driver reading the manual can believe Auto-P will engage when the vehicle is stopped or moving at low speed and the driver unbuckles and exits in a way not covered by the actual system logic. That gap between the manual and the vehicle's behavior is the defect.
There is no warning sign before failure. The vehicle does not give a separate alert that the manual's Auto-P description is wrong, so owners need the corrected manual supplement.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
The original Operator's Manual description of Auto-P can leave a driver relying on the wrong parking behavior. That creates a rollaway or vehicle movement risk and increases the risk of a crash. Treat the original Auto-P instructions as unreliable until the corrected booklet is in place. Repair is free at any franchised Dynamax dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Isata, Sunseeker, Battisti, Prism, Galleria, or Forester is included in this recall.
- Contact a Mercedes-Benz Sprinter dealer to get the corrected Auto-P Operator's Manual information free of charge.
- Call Dynamax customer service at 1-800-348-7440 with questions, or call Sprinter service at 1-877-762-8267 for dealer help.
- Reference recall number 20V358 when you call, and bring the recall notice if Forest River mailed one.
- Use the parking brake and follow the corrected Auto-P instructions until the manual information is updated.
What happens at the repair
At the dealer, staff provide the corrected description of the automatic parking function for the operator's manual, free of charge. The corrected booklet is also available through Mercedes-Benz at no cost. The recall does not require a mechanical parts replacement. Repairs or costs already paid are handled through the vehicle's New Vehicle Limited Warranty, not through a separate reimbursement program.

Frequently asked questions
What is recall 20V358?
Recall 20V358 covers 392 2020-2021 Dynamax Isata, Sunseeker, Battisti, Prism, Galleria, and Forester recreational vehicles built on Sprinter chassis with automatic transmission. The Operator's Manual gives the wrong description of Auto-P operation, which creates a rollaway risk if the driver relies on that description.
What should I do if my 2020-2021 Dynamax Isata, Sunseeker, Battisti, Prism, Galleria, or Forester is on this recall?
Check your VIN to confirm your specific RV is included in recall 20V358. If it is, ask the service desk for the free corrected Auto-P Operator's Manual information. Reference recall number 20V358 when you call, and contact Forest River customer service at 1-800-348-7440 if you need help.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to provide the recall remedy at no cost. For recall 20V358, the remedy is the corrected description of the Auto-P function for the Operator's Manual, provided free of charge.
What is the safety risk?
The safety risk is unintended vehicle rollaway or movement. If a driver relies on the incorrect Auto-P description in the Operator's Manual, the parking function does not operate as described, increasing the risk of a crash.
What if I bought this RV used?
The free recall remedy still applies. Recall coverage follows the VIN, not the first owner. Check your VIN to confirm whether your specific RV is included, then reference recall 20V358 when you contact the service desk or Forest River customer service.
