In addition to this 25TA08 recall notice, my 23 Crown XLE sedan also shows a second recall notice/service campaign 25TD01 Rear Traction Motor Cable Corrosion. Does the Crown Signia also have this recall?
25TD01 Rear Traction Motor Cable Corrosion - Multiple Model & Model Year Toyota Hybrid (AWD) Vehicles
NHTSA Recall ID
AWAITING#
Recall Date
Dealer Reference ID
25TD01
Description
The subject vehicles are equipped with a rear motor unit and an HV Floor Under Wire that provide high voltage to operate the motor. Mud, water, or road salt could potentially enter the HV Floor Underwire connector housing and could cause corrosion over time. Excessive corrosion could cause AM Radio Static during certain driving cycles, or the vehicle may not start.
Status
Remedy Available
Remedy
Any authorized Toyota dealer will apply a wire harness protector seal to the HV Floor Under Wire Connector.
Here's my .02 on the Cablegate issue which is separate from the display blank on startup recall.
Having owned '20 RavxseH, '21 Venza LimitedH, '23 Highlander HiHy, '23 CrownH sedan, and '25H CS I have followed it and after jacking all of them and examining the Rear Traction Motor connector variants in each I am somewhat familiar with the issue.
Original problem surfaced in in '19 era Canadian RavHs associated with corrosion issues in connector failures associated with salt intrusion on heavily salted Winter roads. Salt and salted water intrusion into the wiring within the shielded connector on the RTM. Salted water entered into the connector and with no way to drain, trapped salt water rotted out the metal connectors within the harness causing the rear motor to fail. Quick and dirty solution in mid '21 resulted in ver. 2 Toyota cutting away the bottom portion of the connector so salted water could drain. Worked OK as far as I was concerned becuase there was no corrosion when I traded the Venza in '24. Both my '23 HiHy and '23 CrownH rear motor use the ver.3 same cutaway connector but used a different foam gasket seal. The '25H CS uses a ver.4 connector uses a rubber sleve and gasket over the wires and braided steel grounding cable. Ver.4 provides additional protection for the wires and grounding calble but still remains cutaway for dring of any water intrusion.
Chart below depicts variants and dates of introduction.
The description of the problem and flow chart and qualification for remedy remians the same since the '22 Toy guidance below. Indication of a potential failure is described in the document re. interference on the AM band of the radio. This is an involved expensive procedure with cable replacment costing in the thousands so don't expect Toyota to do anything unless there is a potential failure. Not sure if adding a shield is required unless that is what is referred to in the ver. 4 foam and gasket, but in any even there must be provision for the connector to drain should intrusion occur somewhere upstream in the corregated cable cover.
Upon my asking the Toy techicians always check the connector and report condition during the yearly State safety inspection. On a positive point the open connector in my '23 HiHy has gone through two Winters, the VenzaH through three, with salt and salt spray and the exposed witing and ground shield are free of corrosion. So as far as I am concerned, if it aint broken don't try a DIY shield or cover which could aggravate the situation.
