Subject: Stop Sale notice for certain Toyota Sienna rear entry WAVs

Dear BraunAbility Dealer,

BraunAbility is taking the necessary steps to initiate a voluntary recall on certain Toyota Sienna rear entry wheelchair accessible vehicles manufactured January 9th, 2018- May 20th, 2019. The necessary steps have been taken to file the recall notice with NHTSA and we are proactively communicating this information to you. This notification is to inform you to take the necessary steps to stop sale any affected Toyota Sienna rear entry vehicle(s) you may have in inventory.

Important: Federal law (United States Code Title 49, section 30112) requires you to complete the recall service on any new motor vehicle when it is known the vehicle does not comply with an applicable Federal Motor Vehicle Safety Standard or contains a defect related to motor vehicle safety.

Cause: Brake line extensions manufactured by TFI for use on BraunAbility WAV conversions were assembled using SAE 3/8-24 tube nuts, when the tube nuts should have been metric size M10 x 1.0. The SAE and metric thread forms of these sizes are very similar and consequently, the male SAE thread may be mistakenly assembled to a female metric fitting.

Concern: If the mismatched SAE male tube nut is assembled to the metric female fitting, it may not be possible to achieve the correct assembly torque, and the union may develop a brake fluid leak causing potential braking degradation, which could lead to an accident causing injury.

Correction: Inspection and correction instructions will be communicated to you by Monday, June 10th. If correction is deemed necessary, a brake line adapter will be required for remediation.

Part number: 508884- adapter brake line.

In the coming days and weeks, further detail about this voluntary recall will be communicated to you as part of the NHTSA reporting process.

Please know the safety and reliability of our products are of paramount importance to BraunAbility and by taking this proactive measure we hope it demonstrates our commitment to you and the customers we serve.
