Towing Boat With 2014 Rx350 W/o Towing Package

[quewat]

We are looking at purchasing a Legend boat (aluminum-either 16' or 18'). The towing weight would be between 2100lbs and 2600lbs. We have a 2014 RX350 AWD with touring package, however it does not have a towing package We have an after market Draw-Tite class III hitch installed. Will our 2014 RX350 tow this boat without any concerns? Thank you for your comments.

The towing limits are on page 310 of the 2014 RX350 owners manual which you can view at http://drivers.lexus.com/t3Portal/document/om-s/OM48D08U/pdf/OM48D08U.pdf

with towing package: 3,500 pounds

without towing package: 2,000 pounds

I don't know if is the same for the 2014 RX350 but for the 2015 RX350 the $245 towing prep package consists of "Transmission cooler, heavy-duty radiator and heavy-duty alternator": http://www.lexus.com/models/RX/packages

The differences among Toyota/Lexus vehicles having the same 3.5 liter engine and 6-speed transmission are interesting and don't seem to make much sense. For example, your 2014 RX350 appears to have a standard engine oil cooler which is part of the tow prep package of the 2011-2015 Sienna. The 2011-2015 Sienna has a standard transmission cooler which is part of the RX350 towing package. You'd think that there would be more consistency. Toyota finally made the tow prep package standard on the Sienna starting in 2014 and they should have done the same thing on the RX350.

Edit: Whoops, I didn't notice the OP's Ontario location. Towing equipment and tow prep package availability is not always the same as for the U.S. Here is a link to the 2014 RX owners manual for Canada which seems to state the same limits as for the U.S.: http://s3.amazonaws.com/lexus.site.tci-prod/lexus/manuals/OM48D08U/OM48D08U.pdf
