1990LS400

Well ,,, it's possible that the problem could be in the radio head unit since that is what sends the audio signals to the amplifier. When I had low volume on a Nakiamichi system in a 2000 LS400 a long time ago, the problem was in the in-dash head unit - fixed by a Florida company. When a friend had similar low volume in a 1999 LS400, the problem was an old defective phone ECU that was grounding out and muting the audio system. Uninstalling the phone ECU solved that one. Does your RX happen to have an old Lexus phone system?

My suggestion is to avoid using fuel additives or randomly replacing things and to take your RX to a Lexus dealership for an evaluation. 115000 km is quite low. We have a heavier Toyota Sienna Limited van that has the same engine and transmission as your RX. It is at 95,000 miles (about 153,000 km), runs perfectly and averages from 18 to 24 miles per gallon (13.1 to 9.8 L/100km). It has been maintained according to the maintenance schedule. We live in a warmer climate where temperatures average between -10 to +10 Celsius in Winter but colder temperatures should not make much difference unless you are extensively idling the engine to warm it before driving. The spark plugs should be good to 192,000 km / 120,000 miles. I've always waited to 120,000 mles to change spark plugs per the maintenance schedule and old spark plugs always looked like new. Using premium 91 octane fuel really isn't necessary. Toyota recommends regular gasoline for the same engine in the Sienna and it runs fine on regular.

Did you read the section about EV mode in your owners manual? It starts on page 139 of the 2019 Lexus ES300h owners manual which you can view online at https://drivers.lexus.com/t3Portal/document/om-s/OM06178U/pdf/OM06178U.pdf It's probably working normally. One has to really "baby" the throttle to stay in EV mode in a non-PHEV Toyota hybrid. I've experimented with keeping my wife's Prius in EV mode as long as possible but can't after I drive out of our cul-de-sac due to very slight upward slopes in both directions and needing to go fast enough to avoid antagonizing or getting rear-ended by other drivers. A limitation of non-PHEV hybrid Toyota/Lexus vehicles sold in the North America seems to be their Ni-MH traction batteries. The same vehicles sold in Europe with lithium ion traction batteries have longer EV ranges at higher speeds. EV mode is more useful when the vehicle is just barely creeping along or not moving, e.g. entering/exiting our garage, when stopped at a traffic light or otherwise "idling" and waiting. I like how I can be waiting in line for a car wash bay on a hot summer day in silence with the hybrid system in EV mode and the interior being cooled by the all-electric A/C system. We like EV mode a lot and are leaning towards replacing our 2012 Prius with a 2021 RAV4 Prime plug-in hybrid which should become available later this year - it is supposed to go up to 40 miles at normal street/highway speeds in EV mode before the ICE kicks it. The RAV4 Prime will have a lithium ion traction battery like most PHEV's and full EV's. 40 miles is far more than my wife drives in a typical day. We're also considering the upcoming Tesla Model Y but aren't willing to pre-order without a test drive. A range increase to 320 miles was recently announced for the Model Y.

I can offer only standard recommendations. Try rebooting your iPhone if you haven't already. Try turning Bluetooth on your iPhone off and then back on. Verify that your iPhone has the latest iOS update. (IIRC, there was an iOS update a while back that negatively impacted Bluetooth.) Delete your iPhone from the RX in-dash system. I don't specifically know how the RX in-dash system works but some Toyota/Lexus vehicles of that vintage require separately deleting the phone for hands-free and audio streaming. Re-pair your iPhone with the RX in-dash system. If all else fails, connect your iPhone to the RX aux-in port with a cord - it's a hassle but at least you will be able to listen to audio from your phone. I did that for years on an older car that didn't have Bluetooth. By the way, can other phones stream audio to your RX over Bluetooth without problems? Particularly, something other than an iPhone?

A Lexus dealer can disable the feature with Techstream. I don't know if apps like Carista can do it. Lot's of people have been in the same boat as you. I think it was a Swiss army knife in the same pocket as my car key or fob that pressed against the buttons but my vehicles were in my garage the few times it happened. I got into the practice of removing my key/fob from my pocket as soon as I got home. It's a handy feature in hot weather. I've frequently opened windows, etc. with the key or fob as I approached one of our vehicles to let hot air escape when a vehicle has been sitting in the sun on a hot summer day.

They can be difficult to find outside of a Lexus dealership. People on another forum have mentioned a shortage of the special batteries for the Toyota Highlander with stop/start - I wonder if that is related to your Lexus dealer not helping you. You could ask a Toyota dealership and give them the type code of the battery you need. It might be the same as ones used in the Highlander Hybrid and other Toyota hybrids. The problem with getting a battery from a Toyota dealership is that it might not be warranted for use in your Lexus - at least that's what I was told when I started to buy a battery from a U.S. Toyota dealership for my Lexus.

The ClubLexus forum is at https://www.clublexus.com/ I've been a registered member on this forum and ClubLexus since around 2003. POE = "Port of Entry". All Lexus and Toyota vehicles go through a POE regardless even if manufactured in the U.S. That might be because car manufacturing plants are typically in a special tax zone. Accessories are usually (always?) installed at the POE instead of at the factory if the ordering dealership specifies accessory installation when the vehicle is ordered. It can be substantially less expensive to get accessories installed at a POE than at a local dealership and I suspect the quality is better since people at a POE are installing accessories in a factory-like environment. Car dealers typically outsource the installation of accessories like paint protection film instead of having their own employees do it. It's only less expensive to have accessories installed at a POE if the dealership passes along the savings to the customer. Some don't. Some do. I doubt that we will ever buy another vehicle out of dealer inventory after discovering the joys of special ordering and getting precisely what we want. We're both retired and I doubt that we will be buying many more vehicles. Our main travel vehicle is the 2014 Sienna Limited van referenced in my forum signature. I never thought I would be driving a minivan after 24 years of driving Lexus LS sedans and Mercedes for many years before that but it's pretty wonderful for carrying passengers and cargo. It's quite Lexus-like with it's nice leather interior and memory driver seat ... very similar to a fully optioned Lexus RX but with a usable 3rd row seat. I'm shooting for a 2021 Corvette C8 retractable convertible next year if my wife goes along with it - what every guy in his 70's needs! She's starting to relent.

Several Toyota models (e.g. Highlander, Sienna) used the same brake system that the 2010-2015 Lexus RX used - rotors, pads, everything. I don't remember about the RX but I do remember there being a service campaign that addressed brake disc warping and vibration on the generation 3 Sienna. I have a 2014 Sienna but mine never developed the problems. I did modify components under the vehicle that directed brake cooling airflow per the service bulletin "just in case". I've wondered why I've never had the problems reported by many others especially since my Sienna Limited is heavier than any Highlander or RX and likely stresses the brakes more. One reason might be because I've paid extremely close attention to lug nut torque. Uneven and/or over torquing lug nuts is a known common cause of brake rotor warping. The correct lug nut torque on the RX, Highlander, Sienna and most other vehicles manufactured by Toyota is only 76 ft. lbs. An air wrench should never be used to tighten these lug nuts and they should always be tightened with a manual torque wrench. I've had both Lexus and Toyota dealers tighten lug nuts to over 200 ft. lbs. on too many occasions. One service manager swore that his mechanics never used air wrenches on lug nuts but I then watched as one of his mechanics had to use an air wrench to remove the lug nuts that one of his mechanics had just over-tightened. I've learned to always check lug nut torque with my own torque wrench after someone else messes with my wheels. If I hadn't done that, I wouldn't have been able to change a flat tire on one trip. So ... my 2014 Sienna that has the same brake system as the 2012 RX and is on the original brake rotors and pads front and back at 94,xxx miles. Based on the wear rate, I'll have the original front and rear pads replaced at the same time and the original rotors turned at a little over 110,000 miles when the pads will by then be worn down to the 1 mm minimum specification. Yes, only 1 millimeter of pad thickness is the minimum specification for most Lexus and Toyota vehicles. 1 mm looks scary to the uninformed which is why so many people get scammed into premature brake work. On Lexus vehicles that have electronic brake pad were sensors, the low pad warning in the instrument cluster starts when a brake pad is worn down to about 1.5 mm. My recommendation is to buy a torque wrench if you don't already have one and check and re-torque lug nuts after each time someone removes and re-installs your wheels.

Yes. Green if you have an active subscription. Red if you don't have an active subscription or if you are out of range of a compatible cell tower.

There are many variables that determine how long PPF lasts which you can read about on various websites. The PPF on both our 2012 Prius v and 2014 Sienna was installed at the POE - not by a local car dealership or independent installer. I trust the work of POE installers far more than local installers and the cost is substantially less. I can't detect any yellowing or deterioration of the PPF on either vehicle but both cars have been garaged much of the time since new. My wife's Prius has been garaged almost 24 hours a day due to her parking in a nearby corporate parking garage on weekdays prior to her retirement 3 years ago. The Sienna sat outside on weekdays until I retired a year ago. Both vehicles are metallic white ("Blizzard Pearl") and I suspect the sparkly paint might make any PPF yellowing less noticeable. The color of your ES might be "Eminent White Pearl". I don't see a paint color called "Ermine white pearl" in the list of paint colors offered. The activity level on this forum has significantly declined over the years. If you haven't already, you might research PPF and/or ask questions about it on the far more active Club Lexus forum.

The radio in the 2006 ES was "XM capable" and had the AM/SAT button but the XM tuner was optional. You may need to verify whether or not your radio has the optional XM tuner if you are not sure that it does. I assume that an aftermarket compatible XM tuner is still available if you need one. They were available on eBay for many years for $249.

I suppose the beeper module itself could have failed but I've never known of one failing. When I searched a parts number cross reference, it looks like the same beeper module is used on just about every vehicle that Toyota makes including our Sienna and Prius. The part number appears to be 89747-30040 and the part is called the "BUZZER, WIRELESS DOOR LOCK" in the parts list. The parts diagram for your car doesn't show exactly where it's located - somewhere in the left front fender area? Do you own or have access to just about any other vehicle made by Toyota? If you do, you could switch in the beeper module from another vehicle to see if yours has failed. I just now went out to the garage, raised the hoods on our Sienna and Prius, and then pressed the unlock buttons on their keyless fobs. The beeps "seem" to be coming from inside the engine compartment fuse boxes on the driver side but I'm not certain and it's too cold in the garage for me to want to investigate further. If the beeper is not inside the fuse box, it is very nearby.

According to the "Lexus Navigation Map Update Quick Reference Guide", the generation 6 hard drive based navigation system in the 2010-2012 Lexus HS250h is updated by a Lexus dealership technician using a master DVD and the "NUT" (navigation update tool) through the USB port. It's not something you can do yourself. The updates are available only at Lexus dealers. I'm surprised that map updates have been discontinued. The pattern has been that map updates have been discontinued 9 years after the last model year in which a navigation type was installed. That would be 2013 for the Lexus GX. Based on the pattern, I would expect that 2022 would be the last year that updates for your HS would be available. Who told you that map updates have been discontinued? I suggest you call Lexus corporate customer service and ask if navigation updates for your HS are available but without telling them that someone had previously told you that they have been discontinued.

There are other brands but the 3M paint protective film we have on our vehicles is wonderful stuff. We will definitely have protective film on all future vehicles. You don't have to get it from a Lexus dealer. There are lots of shops that install this stuff. A friend took his new Porsche to a shop here in Kansas and had most of its front end covered with film. Even with film, people have mentioned that it is still necessary to clean the love bugs off quickly since it can still be difficult to remove them after they've dried on to the film. Here's an image from the Lexus website.

Now that you mentioned it, I remember once noticing that the trunk of one of the LS400's we owned from 1990 until 2014 didn't seem to get as hot or cold as exterior temperatures. I never thought much about it although there might have been cutouts in the metal structure under the parcel shelves that passed interior airflow to the trunks. I distinctly remember the exhaust vents in the trunks but all vehicles built by Toyota have those. The attached image shows the left side one on the LS430. With the flight to SUV's and crossovers, far fewer vehicles with separate closed off trunks are being sold these days. I don't see us ever buying another traditional sedan with a closed off trunk but I'm hoping to buy a 2-seat "geezer retirement car" that has closed off trunks when the 2021 models become available. When Jay Leno reviewed the newly redesigned mid-engine 2020 Corvette C8, he recommended putting one's beer only in the front trunk since the radiators are at the sides of the front trunk and the rear trunk is behind the engine. I plan to measure the C8's front trunk at an upcoming auto show to see which one of our Igloo coolers will fit - I plan ahead!

IIRC, the warranty extension on this problem was to 10 years from the car's in-service date but I suggest you take your car to a Lexus dealership and confirm. It doesn't, or at least didn't, matter if you aren't the original owner. 10 years past the in-service date is a common period for a warranty extension like this. A similar 10-year extension was recently announced on several expensive components on one of our Toyotas after a class action lawsuit settlement.

The most direct way to a fix without throwing parts at a problem is to take your car to a professional mechanic who understands these cars.

I suppose you could open the trunk pass through door behind the rear seat armrest. If your LS430 had the Ultra Luxury package with the separate rear HVAC system, that might have been why its trunk temperature was closer to that of the interior.

It might take a Lexus dealer to diagnose the problem. A common cause is a defective antenna. One thing you could try is to have the signal refreshed. IIRC, there is an option on the XM website for refreshing the signal after you log on. Edit: After logging on to the XM website, look for "Refresh My Radio". XM reception varies widely. I live in the Kansas City area and sometimes lose reception while driving down tree lined streets, under overpasses and around tall buildings. I lose the single everytime I pull into my garage too. I listen to XM quite a lot. It's much improved from what it was a few years ago. Edit: One more thing. I've found it best to never start one of our vehicles in our garage with the radio on and set to XM. If I do, reception is poor until I turn the ignition off and back on. I've learned to either turn the radio off when entering my garage or to change the radio from XM to any other source ... FM, Bluetooth, etc.

I suppose you could have a Lexus dealer evaluate your car's drive train "health". Even if the traction battery is declining prematurely, my understanding is that has to be pretty much dead to get any warranty coverage on it. Did your ES come with low rolling resistance tires and, if so, is that the type of tire you are using now? I didn't mention a reason for our Prius decline in fuel economy is that we have stopped using LRR tires on it due to their punishing ride and poor traction. Having Blizzak winter tires on it currently certainly isn't helping fuel economy. Is the ICE obviously running most of the time? Does the ICE shut off when stopped in traffic and when driving down hills? Does the traction battery charging level gauge stay at a low level? Are you doing much stop and go driving that would cause regenerative braking to happen? Perhaps you could sign up on the fuelly website and track your fuel usage there.

EPA fuel economy estimates for the 2012 CT200h are: 43/40/42 mpg (city/highway/combined) EPA fuel economy estimates for the 2013 ES300h are: 40/39/40 mpg (city/highway/combined) Maybe the traction battery in the ES300h is getting weak as it ages and causing to ICE to run more than it did when the battery was stronger. Maybe the ICE in the ES300h has to run more to heat the interior. The ES300h is a lot heavier (3,660 lb) than a CT200h (3,146 lb) and the EPA testing cycle doesn't necessarily take that into account. It's unusual for a vehicle to get EPA rating fuel economy in real world driving. Not many people on the "fuelly" website are getting 40 mpg combined in a 2013 ES300h - take a look for yourself: http://www.fuelly.com/car/lexus/es300h/2013 One has to remember that many people who use the fuelly website are trying hard to get good fuel mileage and using driving techniques not acceptable to most drivers. Our 2012 Prius v has the same hybrid drive train as the 2012 CT200h and weighs about 125 pounds more. It been getting from 33 to 36 mpg the last few tank fulls in city street only driving. It's EPA rating is 44/40/42 (city/highway/combined). 33 to 36 mpg is a long way from the EPA city rating of 44 mpg. Cars often don't get as good fuel economy on winter blend gasoline. Unless you are desperate to same money on fuel, I suggest you reduce the tire pressure to a reasonable level and at least be comfortable.

There is a photo of the location on page 220 under "Emergency towing" in the 1999 RX300 owners manual which you can view online at https://drivers.lexus.com/t3Portal/document/om-s/OM48401U/pdf/OM48401U_edited.pdf

It's going to take a Lexus dealership or an indie repair shop that specializes in these cars to diagnose the problem. Offhand, it sounds like you have a fuel/air mixture issue - maybe a throttle body problem - but only a knowledgeable technician can tell you for sure. These cars are not cheap to keep running as they age.

The pass through from the trunk into the interior is explained in the owners manual on page 248. The trunk release on the inside of the trunk that allows a trapped person to open the trunk is explained on page 24. The owners manual for the 2007 ES350 can be viewed online at https://drivers.lexus.com/t3Portal/document/om-s/OM33729U/pdf/OM33729U.pdf

It's very doubtful that all four wheel caps would become equally fragile and break at the same time but it's pointless to argue with Costco. Maybe a Costco employee thought he had to wack them hard into place not realizing they snap into place with little effort. Or perhaps they were already weakened to some extent. I've never had an OEM Lexus or Toyota center cap break although I've had a few aftermarket center caps break. I've only recently started to have others - usually Costco - rotate my tires ... I'm getting lazy in my old age. I've bought many items from eBay including from eBay sites for European countries. So far I've never had a problem. If the same product is on eBay and Amazon, I prefer to buy from Amazon. If you buy wheel caps from an online seller, be sure to get the size you need. Measure your current wheel caps and verify the size with the seller.
