RX400h

Well, Les I've been running mid-grade in our 400h and it has always had plenty of power and great gas mileage. I'm assuming that your 2020 RX 350 will sell for quite a bit, correct?

Have you had the transmission fluid changed as per the maintenance schedule? If so, have you checked its level? Sometimes, a low level will cause issues like slippage.

Does your audio system power on? Did you check connectors and verify that none is moist? I have read that some owners of IS vehicles had used a hair dryer to dry out the Amp/Amp connectors to get the sound to work.

I believe Lexus techs have a Lexus-specific OBD II scanner. Maybe it IS a 10-minute job that requires an expensive piece of test equipment. (Like having transmission fluid flushed)

I've been perusing on and participating in this forum for over 16 years now and have not seen many door lock issues. If this happened to me I would try to find out the root cause of each failed component or subassembly. It is unlikely that the design has changed significantly over the years. My 25 year old Mazda MX6 GT had never had a door lock fail. I guess if there were multiple kids playing with the lock switches, failure could occur.

A good independent shop would most likely charge quite a bit less than the numbers you listed but sometimes a Toyota dealership can save you a chunk, also. When we needed the spark plugs replaced, the Toyota dealership saved us $200.

Where did you get those costs? It's difficult for me to believe that all of those things need replacing. Our Lexus is close to 17 years old and of all those things listed, only the coolant change was needed as a maintenance item. By contrast, the two chevys I've owned in the past required thousands of dollars spent on component failures and leaks. Lexus is rated #1 as the most reliable auto brand by Consumer Reports. You really should take yours to a more reputable mechanic.

I like Borla, also. Back in 2003 or so I installed their stainless-steel cat-back system on my Corvette. It sounded great. My son and I mounted a Magnaflow cat-back system on his Honda Civic CX. That also sounded great.

I used to work for a company that designed fairly complex circuitry for Doppler systems. Yes, repair technicians would swap out boards to get the customer up and running. But specific engineers would troubleshoot failed boards and write ECOs to correct any design errors to prevent reoccurrences of such failures. It is well known that a zap of static electricity can cause issues after the customer has been using the product. It should happen less frequently in a well set up assembly area but even then, it can happen. Car mechanics are not engineers and would certainly not go beyond simple troubleshooting of circuit boards to see if they do or do not function. Hopefully, the failed unit would be sent back to Lexus. I just recently sent a Coffee machine back to the factory. A water level sensor appeared to have failed. Shortly after my call, the factory sent me a new coffee machine but before that happened, they emailed me a paid shipping label for the failed unit.

You may have to buy a Toyota/Lexus-specific scanner but verify through the vendor/manufacturer that it works with your specific vehicle. I've seen some for $150 on Amazon or Ebay. This review may come in handy. Top 5 Best OBD2 scanners for Toyota & Lexus (youcanic.com)

Here's one possibility: MagnaFlow Lexus Street Series Axle-Back Performance Exhaust System Now if you want to spend less money and don't have to have CAT-back system, you can always go to a muffler shop where a bunch of makes and models of mufflers can be purchased and installed. That way you can hear the sound each one produces before you make a choice. You might want to call first to see what choices they have. Another path is to check out some of the auto parts sites to see what they have to offer, then check youtube to search for a video of that system/muffler on your make and model car.

Felix, have you ever used the services of an auto-electric shop? They specialize in troubleshooting electrical issues, often for dealerships whose techs are baffled. I've used them a few times over the years for other vehicles and they always found the problem very quickly.

Yes, HM, but I would inquire as to whether Lexus has upgraded the defective component (not necessarily the whole unit) in the replacement unit you are receiving. Also, they should warranty that unit for another 4 years. I'm not sure about that but you may want to inquire. If you do decide to sell it, this is good time to get top dollar. Unfortunately, buying a replacement would require spending top dollar.

Of all the Lexus models and years, only one model has had more than its share of issues - the LS500. Consumer Reports shows that the 2018 year is rated as "Much worse than average". There was not enough data from owner surveys for 2019-2021 but my opinion, based upon your experience and CR magazine is that this model from 2018 and on is not a good choice. There is a Lemon Law in California. You should look into it, as well as consider subscribing to Consumer Reports.

A couple of hours? You must be a very experienced garage mechanic! 👍 Thanks for the tips. I wonder if that Florida heat had anything to do with the sensor failure. How many miles are on your odometer?

Try wiggling the key in the ignition (off position) to see if the radio and lights turn off. It may be that the ignition switch needs to be replaced. Typically, that is an easy task.

It is very rare for any model of vehicle to have a flawless reliability record. Consumer Reports receives data from tens of thousands of vehicle owners. CR then publishes reliability tables for each model. The 2019 RX350 table shows that the only below average reliability category is for "Noises/Leaks". This indicates that the issue you experienced is very likely to be scarce. Our RX400h is now almost 17 years old and we have never had any electronics failures in all that time. I would not take your situation as a sign that the vehicle is a lemon. Believe me, if you bought a BMW or Audi, you'd be visiting the dealerships far more often.

The first thing to do would be to have the dealership scan for specific codes. The "Check Hybrid System" and "Check Engine" warnings are generic; they don't pinpoint the cause. That's good to know about the fans. Thanks! Our RX400h has over 130,000 miles on it and has not required any non-maintenance work.

Was your alarm not activated?

I'd say your next step would be to check the radio fuse if the radio is completely dead. Does the radio display come on?

Before anything was done, I would've guessed it was a stuck caliper slide. Most likely, a good alignment shop would've caught the ball joint(s). But it's good that you are back to normal. (and safe on the road)👍

The cost of dental work, especially deep cleaning by laser and periodontal surgery, but also including implants.

Of your two choices, I'd say the MX5 would be both more reliable and easier to work on. Don't discount a salvage vehicle. My 2008 MX5 PRHT was $7000 less than one with a "clean" title. I did my homework by showing a photo of the original damage to a long-time auto body shop guy. He essentially gave me the green light. That was in 2012 and the car has been super-reliable. It does look like you have a natual knack for auto repair; that's great!👍
