MOBILITY VEHICLE ELIGIBILITY

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.

 

NON-APPROVED CONVERSION

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.

Subject to individual review by the dealer and 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.

Because the modifications to this vehicle are unknown to Toyota, there will be no repair instructions available.  If the dealer decides to proceed with the repair, it will up to the technician to determine the best method to remove the fuel tank and replace the fuel pump.  Torque values for reinstallation will need to be determined by contacting the conversion company.

If the dealer decides it cannot complete the repair on a non-authorized conversion due the modifications in that case, the dealer may advise the customer that they have the option of contacting the conversion company for direction. Although the conversion company may or may not be able to provide a solution for the customer, the conversion company may, in the alternative, remove the fuel tank and fuel suction tube assembly, at the customer or conversion company’s expense. In this case, the Toyota dealer could then be able to install the remedy low-pressure fuel pump into the fuel suction tube assembly free-of-charge. The re-installation of the fuel suction tube assembly and fuel tank into the vehicle would need to be performed at the customer or conversion company’s expense by the conversion company in this case.

If upon inspection it’s determined that this vehicle does not use a Toyota fuel pump, as originally designed, email the Quality Compliance Depart (quality_compliance@toyota.com) for further instructions.
