RX400h

This vehicle does use a cartridge-style filter, as seen in the link, above.

Good point. I often can find an electronic version of the service manual, but there are cases when only article/video comments are found. I guess we can say that those should be taken "with a grain of salt".

Thanks for your comments.

When this light comes on, it’s important to get your vehicle inspected by a professional as soon as possible to prevent any potential damage. It’s hard to say exactly what the issue is without a proper diagnosis. Your Lexus dealer or a trusted mechanic should be able to read the specific error code from the OBD system and determine the exact cause of the problem. 

That being said, I should also advise you to check or have checked your battery. Sometimes a failing battery or even a cell with no visible liquid in it can cause very strange warning lights to illuminate.

Hello, Justin. Have you already tried reprogramming the power windows?

1. Turn the key to the on position.
2. At each window switch, lower the window to halfway, then immediately raise it all the way up and hold the switch up for at least 1 second.
3. Repeat this process for all 4 doors

It seems like you’re experiencing an issue with the tail lights on your 2005 LS430. This could be due to a variety of reasons. Here are a few possibilities based on similar issues reported by other Lexus LS430 owners:

1. Faulty Sensor: The tail light sensor might be malfunctioning. Even though the lights illuminate, the sensor checks wattage draw. If the left side is drawing 20 watts, and the right side is drawing only 10 watts, and the circuit is looking for a 40 watt draw, the warning light will come on.

2. Electrical Issue: There could be a loose, frayed, or damaged wire causing the tail lights to come on. It’s suggested to remove the trim in the trunk and look for any such issues.

3. Keyless Entry System: The issue might be related to the keyless entry system, as you’ve noticed the lights go off when you hit a button on your keyless entry, and then come back on after around 30 seconds.

4. Bulb Issue: There could be an issue with the tail light bulbs themselves. If your turn signal doesn’t blink, or blinks rapidly, you likely have a burnt out bulb.

When considering the purchase of a used vehicle, there are several factors to take into account. Here are some points based on the information you provided and my search results:

1. Price: The average price for a used 2004 Lexus GX ranges from $2,979 to $6,302, and the Kelley Blue Book fair purchase price is around $8,295. So, the asking price of $3,000 seems reasonable from a pricing standpoint.

2. Mileage: The car has 265,000 miles on it, which is quite high. High mileage can lead to more wear and tear on the vehicle, potentially leading to more maintenance and repair costs down the line.

3. Maintenance: The car has not had the timing belt or water pump replaced, only simple oil changes. These are important maintenance items that can be costly to replace. The Lexus GX 460, a similar model, is estimated to cost about $7,652 for maintenance and repairs during its first 10 years. You might want to factor these potential costs into your decision.

4. Reliability: The 2004 Lexus GX has a high reliability rating, with an average consumer rating of 4.8 overall and a 4.9 for reliability. This suggests that despite its age and mileage, the car could still be a reliable choice.

5. Inspection: It’s always a good idea to have a trusted mechanic inspect the car before purchase. They can identify any potential issues that might not be immediately apparent.

In conclusion, while the price seems fair and the model is known for its reliability, the high mileage and lack of major maintenance could potentially lead to higher costs in the future. It would be wise to consider these factors and perhaps negotiate the price to account for the potential upcoming maintenance costs. Remember, it’s always a good idea to get a pre-purchase inspection from a trusted mechanic.

It seems like you’re not alone in your experience with the 2023 NX350. Other users have also reported having to apply a lot of brake pressure to shift into Reverse or Drive. This could be a safety feature designed to ensure the vehicle is fully stopped before changing gears, but it can feel unusual if you’re not used to it.

Unfortunately, I couldn’t find any specific information about an option on the infotainment display to adjust the brake pressure needed to release the shifter interlock. It might be a good idea to consult the vehicle’s manual or contact Lexus customer service for more detailed information.

Remember, it’s always important to feel comfortable and confident while driving. If this feature continues to bother you, it might be worth discussing it with your dealer to see if there are any possible solutions or adjustments that can be made. Safe driving! 😊

This seems to be a known issue with some Lexus models, including the LS430¹². Here are a few possibilities based on similar cases:

1. Transmission Solenoid: The shift solenoid is internal to the transmission. To access it, the transmission pan and valve body would need to be removed. A failed solenoid could cause rough downshifts.

2. ECU Issue: Some owners have reported that a replacement ECU or a software update fixed the issue. In one case, an ECU repair costing around $200 fixed a similar issue².

3. Driveshaft Bushings: In some cases, the issue turned out to be with the bushings in the driveshaft.

4. Transmission Replacement: In the worst-case scenario, some mechanics have suggested replacing the transmission altogether. However, this is a costly service and should be considered as a last resort.

I understand your concern about the brake booster check valve in your 2008 Lexus ES 350. It seems like you’ve done a thorough job of troubleshooting the issue.

The brake booster check valve is typically located on the brake booster assembly. However, it appears that locating the check valve in a 2008 Lexus ES 350 might be a bit tricky.

According to a Lexus parts website, the part number for the Power Brake Booster Check Valve for a Lexus ES 350 (2007 - 2020) is 4473028030. You might want to consider contacting a Lexus dealership or a knowledgeable Lexus technician for support.

As for the hard brake pedal issue, it’s indeed a common problem with the Lexus ES 350. The issue could be due to various reasons such as worn brake pads, contaminated brake fluid, or broken brake rotors. If the problem persists after checking the brake booster and the check valve, it might be worth having a professional mechanic inspect your vehicle.

It sounds like you’ve done a thorough job checking and replacing parts. Here are a few suggestions based on the information I found:

1. Check the Coolant Temp Sensors: Faulty coolant temp sensors can sometimes cause revving issues.
2. Check the Throttle Position Sensor (TPS): A faulty TPS could potentially cause revving issues.
3. Check the Idle Speed: If the idle speed is too low, it might cause the engine to die when put into drive.
4. Check for Clogged Fuel Injectors or Dirty Engine Valves: Gradual power loss, sluggish acceleration, and lowered fuel economy can be caused by dirty fuel injectors, dirty engine valves, and combustion chamber deposits³.

If none of these suggestions resolve the issue, it might be worth considering the IAC valve. However, it’s always a good idea to exhaust all other possibilities before investing in a pricey part. 

It looks like this sound was not present when you bought the vehicle? Is your RX still under warranty? If there is a Toyota-equivalent vehicle, then typically the service cost would be less expensive than at a Lexus dealership. I've had our spark plugs and coolant changed at our local Toyota dealership. Its reduction in cost for the maintenance tasks were significant.

Hello, Bill. Who tested the battery, and was it load-tested? Obviously, not starting after one week is not normal. Is your remote fob battery good?
If that battery is week, you can sometimes verify by placing the fob against the vehicle's start button as you press that button. A weak fob button can often allow the vehicle to start if you do it this way.

I understand your frustration with the issues you’re experiencing with your Lexus RX300. Here are some suggestions based on the symptoms you’ve described:

1. Intermittent Misfire: This could be due to a variety of reasons including faulty spark plugs, ignition coils, or fuel injectors. It’s recommended to check each coil one by one to see if there is a change in the sound or rpm of the engine. If there is no change, that means the coil is bad and needs to be replaced. You can also swap the bad coil with a good one to confirm that the problem is not the spark plug, the injector, or the wiring.

2. Low Vacuum Condition: A low vacuum condition can be caused by a variety of issues including a clogged air filter, vacuum leaks, or issues with the valve covers. It’s recommended to check for vacuum leaks as a first step. If you suspect it’s not a vacuum leak, it could be related to the valve timing as you mentioned.

3. Valve Timing/VVT System: Issues with the VVT system can cause a variety of symptoms including diminished engine performance and poor fuel economy. If you suspect the VVT system, it’s recommended to check the VVT solenoids⁷. You can also consider replacing the VVT solenoids as you mentioned.

4. Idle Air Control Valve (IACV): If the car idles roughly or stalls, it could be due to a dirty or faulty IACV. Cleaning the IACV can often resolve these issues. You can consider cleaning the IACV as you mentioned.

I have the same issue of CR and was surprised to see that. You may want to call service advisers at one or more dealerships to inquire about this issue. I don't recall seeing any other comments about this year Lexus model NX300h. Also try this forum's search function if you haven't already.

There could be several reasons why the touch screen of your 2003 Lexus LS 430 is working sporadically:

1. High Ambient Temperature: Sometimes high ambient temperature conditions can have adverse effects on electronic displays.
2. Loose Electrical Connection: Another possible culprit could be a loose electrical connection.
3. Display Fading or Failing: Some owners have experienced issues with the display fading or failing to function properly over time.

If the problem persists, it might be a good idea to have it checked by a professional. You could consider taking your car to a dealership, as they might have technicians who have experienced this issue before¹. Alternatively, you could also consider an “Auto-Electric” shop that employs electrical troubleshooting specialists. They may be able to check and possibly solve the problem at a lower cost.

The intermittent vibration under the hood of your 2008 Lexus RX400h could be due to several reasons:

1. Engine Bay Fan: The vibration and noise could occur when an engine bay fan turns on. It’s possible that the issue is intermittent and doesn’t happen every time the fan is on.

2. Faulty Fan Mount: A busted fan mount could also cause such vibrations. You can test this by turning on the AC, which activates the fans, and see if that causes the vibration.

3. Engine Mounts and Wheel Bearings: Check the engine mounts and front wheel bearings as they could also cause vibrations².

4. Worn Out or Faulty Sparkplugs: In many vehicles, a common cause of engine vibration is worn out or faulty sparkplugs. Worn out or dirty sparkplugs will cause the engine to misfire or not properly fire on each and every cylinder.

5. Tires or Alignment: If the vibration occurs during normal driving whether you’re accelerating or coasting, it could be caused by the tires or the alignment.

6. Brake Pads: The vibration could come from the brake pads applying pressure unevenly across the brake rotor surface.

Since the issue is intermittent, the dealership should keep your vehicle, overnight if necessary, and run it when it is cold and fully warmed up. This is a common procedure when an issue is intermittent.

I would recommend looking at looking at OEM wheel specifications for each car on the tirerack.com site.

You can also give them a call for their expert advice.

The jerking you’re experiencing when your 2011 Lexus RX350 shifts between first and second gears at 20mph could be due to a few potential issues:

1. Transmission Fluid: If the transmission fluid is old or not at the proper level, it could cause hard shifts. Checking the transmission fluid dipstick could give you an idea about the condition of the fluid.

2. Gear Ratios: Incorrect gear ratios could also cause hard shifts¹.

3. Shift Solenoid: A faulty shift solenoid could lead to jerky acceleration and potential damage to the transmission.

4. Torque Converter: If the torque converter fails, it can cause heavy jerking in certain conditions, often between the first and second gears³. The torque converter has friction plates that act as a simple clutch and can have issues with lubrication and cooling.

It’s recommended to have your vehicle inspected by a professional mechanic to accurately diagnose and fix the issue. They might suggest checking the transmission fluid, inspecting for excess metal shavings, changing the filter, and refilling with Toyota WS trans fluid². Please note that these are just potential causes and the actual issue might be different. It’s always best to consult with a professional.

Noticing transmission oil on the transfer case of your 2007 Lexus GX470 could be a sign of a minor leak. However, if it’s not leaving stains on the ground, it might not be a significant issue. Here are a few things you could consider:

1. Check the Fluid Level: If you’re comfortable doing so, you could check the fluid level in the transfer case. If the fluid level is low, it might be a good idea to add more¹. The transfer case of a Lexus GX470 typically takes about 1.5 quarts of gear lubricant oil.

2. Inspect the Seals: The oil could be coming from a worn or damaged seal. If this is the case, you might need to replace the seal.

3. Monitor the Situation: Keep an eye on the situation. If you start to notice more oil or any changes in your vehicle’s performance, it might be time to take it to a professional for a more thorough inspection.

Remember, when in doubt, it’s always a good idea to consult with a professional mechanic or your local Lexus dealership. They can provide you with the most accurate advice based on a physical inspection of your vehicle. Safety should always be your top priority.

Based on your description, it seems like the microswitch might be functioning correctly if you hear a solenoid clicking when you depress it. The issue might be with the liftgate struts or the power liftgate motor.

Here are a few things you could consider:

1. Liftgate Struts: Over time, the gas struts that help lift and hold the liftgate can wear out and may need to be replaced. If the struts are weak, they may not be able to lift the gate or hold it open.

2. Power Liftgate Motor: If the motor that raises and lowers the door is not doing anything, it could be a problem with the power liftgate motor². You might need to replace the power liftgate motor.

3. Pinch Sensors: If the door is acting up when closing, it might be an issue with the pinch sensors.
