Replacing the tires shouldn't have affected the TPMS. If the TPMS was working with the old tires then they should be working with the new ones. I suggest you take your RX back to Discount Tire and have them diagnose the problem. Perhaps they damaged one of the sensors during the tire changeover. It wouldn't be the first time a tire shop has done that. I doubt if one of the TPMS batteries would be low after 7 years but that's possible - but too much of a coincidence if the problem started immediately after getting new tires. I love TPMS. It's save both my wife and me a lot of trouble. TPMS has twice allowed me to get to the next Interstate highway exit before tires went flat so I could address the problem without vehicles whizzing by me at high speeds while stopped on a shoulder. My wife has had several leaking tires while driving in town and TPMS has given her time to drive to a shop before tire went flat. It's impossible to tell if many low profile tires are low on air just be looking at them like we could in the old days of 70 or 75 profile tires. I don't know which model year the RX got a TPMS system that automatically learns TPMS codes. I don't know if any vehicles are still made that have the type of TPMS that has to be programmed with electronic devices.

I haven't owned a Lexus since selling my 2000 LS400 to a friend in 2014. I drove a 2014 Toyota Sienna Limited van from 2014 to 2022 when I sold it to another friend and bought a new Porsche Cayenne. I had planned buy the new Corvette I mentioned but it never got the safety features I wanted. I'm not sure what the Cayenne is. Put it in Sport Plus mode and it handles like a hard core raucous sports car. Put it in Normal mode and it's like a serene limo. I've for decades kept an ever changing prioritized list of the features I want in a new vehicle. A trailer hitch - either OEM or aftermarket - is a nonnegotiable item on the list. I don't buy a vehicle if it doesn't have or I can't get a trailer hitch for it. Having a requirements list makes it easier to identify suitable vehicles. For example, we had planned to replace the Prius v wagon my wife drives with a Toyota RAV4 until I found out that some important features weren't available on it. After finding that the features missing from the RAV4 were available on the similar Lexus NX, we got on a wait list for one. By the way, an OEM trailer hitch is available for the Lexus NX.

I suggest removing the mirror from you RX and looking at the repair possibilities on a work bench. I haven't removed an exterior mirror from an RX but I've removed and disassembled mirrors on other vehicles made by Toyota including ones that power fold. It's not all that difficult to remove and reinstall but it usually does require removing the door panel. All you need are interior trim tools, medium size Phillips screw driver and a metric socket set. Or purchase a used exterior mirror assembly and have it repainted if necessary. Maybe the paint won't match perfectly but after all it's a 17 year old low value vehicle. No one except you will notice if the paint match isn't perfect. There are videos on YouTube on removing RX mirrors that I easily found with Google.

Maybe you should seek medical advice. People can develop allergies as they age and some non-allergy maladies have allergy-like symptoms. For example, I wasn't allergic to poison ivy until I got into my 60's and now I'm terribly allergic to it. Similarly, mosquitoes didn't bite me until I got into my 60's and now they feast on me. It's the same with pollen - allergies got much worse as I aged. My take is that Toyota/Lexus still can't be beat for quality, low maintenance requirements and freedom from repairs. Most surveys I've seen support that such as this recent one: https://www.jdpower.com/business/press-releases/2024-us-vehicle-dependability-study-vds In 2022 we broke our 32 year string of buying only Lexus and Toyota brand vehicles and bought a new Porsche Cayenne SUV looking for a better driving experience. We got a pretty remarkable driving experience but the Cayenne has required more visits to the dealer for repairs (mostly software related) in two years than any Toyota/Lexus vehicle we've owned has required in 8 to 14 years. I'm already thinking that I'll go back to Lexus when I'm done with this Porsche. If your Lexus really is causing your illness, can you dump it and buy something else? It doesn't seem reasonable to continue driving a vehicle that compromises one's health.

It appears so which is pretty typical of car forums if they allow any at all. It's best to provide year and model whenever you post about a particular vehicle. You could also create a custom signature containing a list of your vehicles which would automatically appear in each post you make.

Are you absolutely certain that nothing in your purse pressed against the hatch button on your fob? This has happened over and over on multiple vehicles when something in my wife's purse pressed against a vehicle fob button. It was so frequent on our Porsche Cayenne that I bought a case for that fob that made it impossible for it to happen again. Goggle something like "key case for lexus rx500h key fob" and maybe you'll find a case you like that can prevent or at least reduce the problem.

Be very cautious. If it sounds to good to be true, It's likely too good to be true. A post on the Club Lexus forum said that this is a Russian website selling pirated software. Take notice of how few times the people in this thread have posted on this forum.

The parts diagram shows the navigation hard drive as being on the right (passenger) side of the trunk. I'm not very familiar with the GS but on the 1998-2000 LS400 like I had, the navigation hard drive was under a false floor on the right side of the trunk along with the ECU for the factory installed telephone system.

Try a salvage company. For example, there are twenty-eight 1995-2000 LS400 at Pick-N-Pull salvage years scattered around the U.S. I also found salvaged rear differentials on eBay. According to a part number cross reference, the 1995-2000 LS400 use the same rear diff.

Probably not. TPMS is a federal requirement which is why reputable tire sellers will not mount new tires unless TPMS is functioning. You should be checking the pressure in your tires when they are cold and much more often than only at tire rotations. Tire pressures increase and decrease about 1 psi for every 10 degrees Fahrenheit change. I sometimes have to correct tire pressures more than once a week if there are big temperature swings. Costco's price for TPMS is pretty good. I bought and had Costco install TPMS on the winter wheels I bought for my Porsche last fall. In fact, I've bought all our tires except one set from Costco since 2001 when they opened a store nearby. Discount Tire is pretty good too but Costco almost always beats them on price either up front or with the annual Costco member giveback check. Some Costco stores have nitrogen air pumps out front if you want to use them but be sure to recheck your tire pressures when they are cold. Does the 2009 RX350 have a full size spare tire with a TPMS sensor? You might have TPMS only on four tires. I'm a strong believer in TPMS. Getting a low pressure alert has helped me get to a safe area several times where I could either change the tire or add air with the portable compressor I carry so I could limp it to a tire shop for a tire repair .... or tire purchase if the tire was ruined. The last thing I want to do is to change a tire while semi's are whizzing by me on a busy highway.

Yes, streaming audio from a cell phone uses cellular data. The amount of data used varies depending on application and how much it is used. I don't remember how much data the SiriusXM cell phone app uses since the last several vehicles we've purchased have had built-in sat radio. You could also buy a separate SiriusXM tuner and likely output its audio to a cable that would plug into the VAIS aux-in jack. But why bother at this point. Sat radio isn't really from satellites in many areas anyway but instead is broadcast from ground based repeaters.. The money you spend on installing a separate SiriusXM tuner is better applied to a more robust data plan in my opinion. Unlimited data plans or data plans that provide a massive amount of data are fairly common and inexpensive these days. When I was daily streaming Pandora from my cell phone to my modified radio in my 2000 LS400 10 years ago, I doubt that it ever took more than 1 or 2 GB of data per month. I haven't used the SiriusXM cell phone app in several years but from what I remember it sounded better than sound from a built-in SiriusXM receiver. In my current daily driver (2022 Porsche Cayenne), 99% of what I listen to is streamed from the Internet. We even listen to local radio stations on the Internet based TuneIn service when we travel out of our home area. Steaming from a cell phone opens up all sorts of possibilities. For example, I burned my entire music collection from CD's to my cell phone. Doing that requires a decent amount of storage on a cell phone but not that much compared to how much storage many modern cell phones have. My current aging Samsung S10 phone has 512GB of built-in storage and a 512GB removable SD card for a total of one terabyte. I doubt that my personal music collection takes up even 5% of the total storage. Another cool aspect of doing everything from your phone is that it's portable. You can stream from your phone to other vehicles, wireless Bluetooth speakers or just listen to the audio (including SiriusXM) with earbuds. As you can see, once I get started on this stuff, I have a hard time stopping!

I answered in your other thread:

Weren't your original wiper blades of the "conventional" type? See the attachment showing the types. Beam type (also called "flat") wiper blades often work poorly on curved windshields - even on slightly curved windshields. If your original blades were of the conventional type, then go back to using those.

It looks like VAIS still sells aux-in kits for your car: https://vaistech.com/ You could stream SiriusXM from the SiriiusXM cell phone app by either connecting your cell phone directly to the aux-in or adding a bluetooth adapter to the aux-in and streaming wirelessly. SiriusXM sounds quite nice when streamed from its cell phone app. This aux-in would allow you to stream whatever you want from your phone ... Pandora, Spotify, Amazon Music, YouTube Music, etc.
