  1. Why not replace your 2013 RX350 with an SUV that can tow your boat safely with no drama and also carry at least as many passengers as your RX? It would probably be less expensive than owning an extra vehicle. If you don't want to buy new, I'm sure you can find something nice on the used market that would work for you. For example, the Carmax down the road from me here in Kansas has Chevy Suburbans from 2013 to 2019 priced between $25K and $37K. The purchase price of a boat is only the beginning. I was stunned at all associated costs. I swore I'd never own another boat unless I could
  2. A unit body vehicle like the RX cannot be "beefed up" to handle that kind of load. I suppose you could ask around but I strongly doubt that anybody in their right mind would assume the liability of doing that type of job. You've just plain got the wrong vehicle for towing that kind of boat. Some versions of the F-150 wouldn't tow that boat either. The marina service I used to recover our sailboat used a much larger 4WD pickup truck - something on the order of an F-350 - but they were sometimes launching and recovering boats that weighed well over 10,000 pounds. You need someth
  3. The Ford F-150 is a "body on frame" design and engineered from the start for heavy towing. The RX350 is a unit-body vehicle without a separate frame and is designed for light duty towing at best. Trailers over around 1,500 pounds should have their own brakes - electric or surge. Trailers over 3,000 pounds REALLY need their own brakes. Trailers for boats of the size you are talking about usually have surge brakes since electric brakes aren't happy being submerged. Boat ramps can be scary slippery with moss in the Midwest but maybe that's less of a problem in Florida. I once had a sca
  4. I doubt that you would get ticketed anywhere in the U.S. for not having rear side marker lights and certainly not in the Florida keys "Conch Republic". Is anything illegal down there? 🙄 Does your replacement lamp unit have a manufacturer name and/or part number on it or does the box it came in have it? It would be interesting to see what it really is. Here's an image I grabbed from Amazon that shows the back of the type of lamp module you needed. It has a socket for a 5W side marker bulb. If the lamp unit you bought instead has only a socket for a larger 21W rear fog lamp bulb t
  5. OK, another possibility that I hesitated to bring up is that a rear fog lamp unit may be involved. In most areas outside North America, the lamp units in the rear bumper are fog lamps instead of side marker lamps. These rear fog lamp units use 21W bulbs instead of the 5W bulbs used in the side marker units. The attached diagram and parts list shows the rear fog lamps for the European market RX. There are a number of possible scenarios including ... 1) A previous owner removed the rear side marker units, installed the rear fog light units, and did the necessary rewiring to support
  6. My understanding is that security codes were not used on Toyota/Lexus vehicles sold in North America after the early/mid 1990's. For example, my 1990 LS400 radio had an option for entering a security code but my 2000 LS400 did not. The security code feature was documented in the owners manual for the 1990.
  7. I wonder if you got the wrong version of the light unit. Determine where your RX was assembled - Japan or North America - and verify that the part number you were sold matches the one in the appropriate attached image.
  8. Here a parts list for both rear tail lights. Google the part numbers for sources.
  9. If your 2012 RX has the optional heads-up display, it includes current speed displayed in digital format. Press the "HUD" button on the lower right of the dashboard to turn it on.
  10. No. Why would you want your current speed to be shown on the nav screen? If you instead meant to ask if the current speed limit can be shown on the navigation screen, I think 2016 generation 4 RX was the first year that the RX got that feature.
  11. Turn the A/C off. It's done on the audio/navigation screen.
  12. My opinion is that the blade is more important than the arm. Your rubber wiper blade insert should have a slot on each side for a metal rib. The metal ribs that fit into the slots are curved. It's important that the curvature of the metal ribs matches the curvature of the window when inserting the metal ribs into the slots in the rubber insert. If the curvature of the metal ribs is reversed, the wiper blade won't contact the glass well through its sweep. If you purchased an aftermarket wiper blade that doesn't use the two reusable curved metal ribs, then that's likely the problem ...
  13. You might try reinstalling your original wiper arm and blade if you still have them and replace the rubber blade insert with a new OEM one. It's rare for a wiper arm to wear out. We've kept a number vehicles for from 10 to 14 years and have never needed to replace a front or rear wiper arm. I don't know what kind of aftermarket blade you bought but some don't have the little spring arms that the OEM blades have that allow them to conform better to curved glass. I tried aftermarket wiper blades on the 2000 LS400 I drove for many years and they didn't begin to conform to its curved glass
  14. Did you replace the entire wiper blade or just the rubber insert? If you replaced either, did you use OEM parts? Unfortunately, the effectiveness of rear wipers on windows with curvature is sometimes marginal. The rear wiper on our Prius v wagon's flatter rear window works better than the rear wiper on our Sienna van's window that has more curvature. Something else you could try is to thoroughly clean the rear window glass and wiper blade insert with denatured alcohol to remove road film and general crud. I do that several times a year on our vehicles with rear wipers. It's surprising ho
  15. The most common cause of this problem is failure of the stop light switch on the brake pedal arm. Are your brake lights lighting up when you press the brake pedal? OEM brake light switches sell for gen 1 LS400 sell for around $75 but I see aftermarket ones online for far less. Autozone has several brands of them for as little as $27.
  16. I'm also seeing the left and right turn signal wires only at the driver side junction block and combination meter in your electrical diagram - surprising. I see the right sign turn signal wire color (G-Y) referenced at the bottom of the diagram for the passenger side junction block but not on the diagram itself which is confusing. Looking at electrical diagrams on a small laptop PC screen is NOT my favorite activity! It's possible that the LS430 is different than other recent vehicles from Toyota in this respect. Or maybe only the UK/European version of the wiring diagram shows the tur
  17. There are likely turn signal wires on connectors to the junction blocks near the kick panels in both the driver and passenger sides as there have been on most vehicles made by Toyota in the past few decades. When I added mirror covers with turn signals to our 2012 Prius v, I used an inexpensive unpowered 12V test light to locate the turn signal wires in its similar junction block connectors near the driver and passenger side kick panels. But if you want to use the power source you already found, you should be able to run a wire above the lower trim panel on the driver side, behind the au
  18. There are a LOT of reviews for the gen 4 RX Curt and Draw-Tite hitches on the etrailer website. People seem pleased with them. I see that the installation difficulty rating for both is "3 out of 10" which is about the easiest rating that etrailer gives for installing receiver hitches. I've bought a lot of stuff from etrailer including the receiver hitches on our current vehicles, wiring harnesses, bike racks, etc. The appearance of the Curt hitches I've bought has held up a little better than the only Draw-Tite hitch I've bought but that may have been a coincidence. There are a lo
  19. The battery in one or more of your TPMS sensors may have failed. An internet search indicates that the batteries last between 5 and 10 years. My understanding is that the batteries cannot be replaced and that it is necessary to purchase new sensors and reprogram the vehicle ECU with the ID codes.
  20. I've used a mechanics stethoscope several times to track down interior noises. They are fairly cheap ... I see one online for about $12. Sometimes I've had someone else drive while I probed around the interior with my stethoscope. The sources of the noises have usually been something rattling around in the center console, glove compartment or door pocket. The source of a particularly nasty buzz turned out to be a loose setting in a ring on my right hand which was pretty funny - the buzz occurred only when my right hand was on the steering wheel. Another common source of buzzes
  21. The hydraulic hood support struts are worn out. A sign of wear is when they keep the hood up in warm weather but not in colder weather. Here are the OEM part numbers from SUPPORT ASSY, HOOD, RH - 53440-0E020 SUPPORT ASSY, HOOD, LH - 53450-0E010 Googling the part numbers should find both OEM and aftermarket replacements. They are fairly easy to replace. I've replaced several sets
  22. It has been 17 years since I sold my 1990 LS400 so my memory could be hazy. Can you essentially deactivate the tilt/telescope by moving the steering wheel to your preferred driving position and then setting the Auto button on the left side of the steering column to its "off" position? The "off" position for this button is when it is extended. The 1990 LS400 owners manual shows fuse #27 as being for the steering wheel and seat belt anchor but pulling it will also deactivate the power windows and sunroof. I don't know if the tilt/telescope can be deactivate through the diagnostic port.
  23. It is usually necessary to pull audio system head units to access their antenna connections. If you are going to the trouble of pulling the head unit, consider installing a device that allows you to stream audio from your phone through an aux-in cord or wirelessly through Bluetooth which should provide far better sound quality than an FM modulator. VAIS Tech has been selling these interfaces probably longer than anyone else. Stores like Best Buy might have them too or just do an internet search. I see some on Amazon. Here is a link to the VAIS website: Here
  24. Summarizing the three methods for carrying bikes that have been mentioned in this thread: 1. Use a general purpose bike rack that attaches to the trunk/hatch door with straps. 2. Buy the UX cross bars and attachments for carrying bikes on the roof. 3. Have a custom receiver hitch fabricated and use a hitch mount bike rack. I can think of a forth option but it would likely be the most expensive one. Buy the European market hitch for the UX and the European market bike rack that can be mounted on it. I bought European market parts from a Lexus dealer in London in the earl
  25. A suggestion is to read the previous posts in this thread and take action based on what others have found.
