FOR
SAFETY RECALL 20TA02
VEHICLE MAY STALL DURING DRIVING AT HIGHER SPEED
2017 – 2020 SIENNA MOBILITY VEHICLES
These instructions are only for 20TA02 Sienna vehicles that have been converted for mobility use by an authorized mobility conversion company. All other models are detailed in separate instructions.
BACKGROUND
Are Sienna vehicles that have been converted for wheelchair accessibility able to have the remedy performed?
Only vehicles that are converted for wheelchair accessibility by a Toyota-authorized mobility conversion company are compatible with the remedy.
Who are the authorized mobility conversion companies?
Below is the list of companies that are authorized by Toyota to convert Sienna vehicles for wheelchair accessibility.
- The Braun Corporation (BraunAbility)
- Vantage Mobility International (VMI)
What if a vehicle is converted by a non-authorized mobility conversion company
Sienna vehicles that have been converted for wheelchair accessibility by a non-Toyota authorized mobility conversion company have undergone an unauthorized modification to the factory condition of the vehicle. These vehicles may be incompatible with the remedy in their current modified condition. Toyota does not recommend modifying vehicles and cannot evaluate how any aftermarket, non-Toyota approved parts and/or modifications could affect a vehicle’s performance.
Notwithstanding Toyota’s recommendation, some dealers may be willing to perform the Safety Recall remedy with the vehicle in its current modified condition. If your dealership is willing to do so, the customer may be responsible for the cost of parts and/or labor not otherwise covered by Toyota’s Safety Recall. Toyota provides the specific remedy parts, differential oil (AWD-only), and covers 2.6 – 2.7 hours of dealership labor expenses. The customer is responsible to pay any additional charges for parts and/or labor which are the result of the vehicle’s non-Toyota-approved modifications.
Toyota is not responsible for later performance problems the vehicle may have that are the result of the non-Toyota-approved vehicle modifications.
CHECK FOR FLOORBOARD & FUEL TANK MODIFICATIONS
Inspect the vehicle to determine if modifications have been made to the floorboard of the vehicle to accommodate a ramp or lift for wheelchair use. Such modifications typically require the relocation and/or modification of the fuel tank. If the fuel tank has not been modified or relocated, use the non-mobility 20TA02 Technical Instructions.
The subject vehicles are equipped with a low-pressure fuel pump which may stop operating. If this were to occur, warning lights and messages may be displayed on the instrument panel, and the engine may run rough. This may result in a vehicle stall, and the vehicle may be unable to be restarted. If a vehicle stall occurs while driving at higher speeds, this could increase the risk of a crash.
