RX400h

Hello, Randy. Have you already checked rockauto.com? Lexus OEM parts - Search (bing.com)

Ours has more than 136,000miles on it and still running great.

You might want to peruse these technical service bulletins: 2001 LEXUS RX Technical Service Bulletins (TSBs) - ClubLexus - Lexus Forum Discussion

Have you tried using a code reader to see if there are any current codes? You can also bring your vehicle to an auto parts store to see if they can check.

Most of the time, the culprit is one or two things: 1. Air in the brake lines - requires a thorough fluid flush 2. The master cylinder seals are worn. This can be due to age/frequency of use or when someone bled the fluid, he had someone press the pedal all the way to the floor, repeatedly. Your master cylinder piston typically travels approximately half of the total distance. Over time, the cylinder can wear up to that point, leaving a "lip" in the cylinder wall. When someone pushed the pedal to the floor to bleed the system, the piston seal can be damaged, resulting in leakage. Start with #1 to see if that fixes the problem.

Much depends on the length of the drive when you take the vehicle out. With ANY ICE or hybrid vehicle, if you drive 5 miles to go to a store or other destination, then drive home, the alternator may not be charging the battery sufficiently. Whenever I take any of our vehicles out, and my destination is a short distance away, I purposely travel further down the highway, turn round and come back. My batteries last close to 5 years each. A battery "tender" is not needed unless I am traveling on vacation or work and will be gone for many weeks.

There was a big discussion about a similar issue, but apparently it was AWD LS460s. The TSB on page two starts with model year 2012, I believe.

When you can't turn the ignition key, try tapping the rear of the key and then trying again.

Is it just the license plate frame?

What happens if you place the transmission in neutral and raise the engine rpm? (When the engine had been warmed up)

Do you have a mechanic's stethoscope? That would help pinpoint the source. My initial guess would be a loose/worn belt or pulley bearing. I agree that it should not be the transmission unless perhaps it has 400,000 miles on it.

This statement by Cduluk may have something to do with it:

That is very odd. By the way, many years ago, one of our keys was not going all the way into the ignition, which prevented it from enabling the ignition switch to rotate. I had to tap the key to get it to go all the way in. Once I did that, I could rotate the ignition switch and pull out the key. I then squirted some powdered graphite into the key opening. That was over 10 years ago, and we never had that issue again.

Ah, so you may be able to scratch that off the list.👍

At what temperature are they (fans) supposed to come on?

Why would you need one?

Does it still vibrate if you let off the gas? It looks like it could be a suspension issue.

Other than the oil hose leak (which should've been upgraded to the hard version), Consumer Reports' 2018 Buying Guide shows that the 2011 RX450h has had no problem areas when they were 7 years old. Our 18 year-old RX400h has been near perfect.

1. See if you get ahold of a maintenance schedule for the vehicle you are interested in. 2. Conduct a phone interview with the owner and ask if and when the required maintenance was completed. 3. If you are satisfied with the answers, schedule an in-person visit. If you are not a hands-on type of person, you want to bring someone who is familiar with how to check fluids for color and levels. 4. You can also pay an auto repair shop to do a complete inspection. Having a lift really comes in handy for looking at the underside of the vehicle.

A head gasket leak can result in coolant expulsion. Many auto repair shops can test your coolant to determine if super-hot combustion gasses have entered the coolant. Here are other ways to check for a blown head gasket: How to Find a Blown Head Gasket Problem (2carpros.com) If excessive air is in the coolant, due to insufficient bleeding after a coolant change, this could also cause coolant expulsion from the reservoir tank.

Consumer Reports published an issue, last November in which they wrote, "Why Hybrids Are a Smart Choice Right Now" Here are their three main reasons, plus one of my own: 1. Most hybrid SUVs get more than 35 MPG, and most hybrid sedans get more than 45 MPG, That's significantly more than non-hybrids. 2. Unlike pure electric vehicles, you don't have to plug in a hybrid. Simply refuels in minutes at any gas station. 3. Hybrids tend to have far better range than EVs. 4. CR's tests show that the hybrid versions of many cars have more power and smoother acceleration than gas-only cars. While EVs may save money in the long run, many EV manufacturers have no lengthy lithium battery history on which to base a reliability rating. And let's face it, EVs can be very expensive to buy. Plug-in vehicles have short ranges and like all ICE vehicles, can have issues if the engine runs for only a short period of time on a consistent basis. Personally, I would not buy a plug-in for that reason. This is why I believe a regular hybrid like the NX or RX versions get very high ratings. Yes, Toyota/Lexus vehicles retain their values better than most other brands. By the way, I think your ES300h is one of the best cars on the market. My sister recently bought one and she is getting amazing fuel mileage.

Purchasing an extra key/fob can cost $500 from an auto locksmith. While it is convenient to have two keys, I've often had only one after buying a used vehicle. It was never that big of a problem, especially considering the cost of an additional fob. Have you tried to find out when the second fob will be available?

I would check the maintenance schedules to see if the transmission filter needs to be replaced at a certain mileage or number of years. In some cases, as long as filters are changed according to the schedule, no filter change is required.
