Lexus GX 470 owners often wonder about the recommended transmission fluid change interval. Let’s delve into this topic:

1. Official Recommendation:

   • While your service advisor’s response is not uncommon, it’s essential to consider the official stance. Lexus does not classify the transmission fluid as “lifetime.” Instead, they recommend regular maintenance.
   • The official guideline is to change the transmission fluid every 30,000 miles. Regular fluid changes help maintain optimal performance and extend the life of your transmission.

2. Why Change the Fluid?:

   • Transmission fluid serves several critical functions, including lubrication, cooling, and cleaning. Over time, it can break down, accumulate debris, and lose effectiveness.
   • Regular fluid changes prevent premature wear, reduce the risk of transmission issues, and promote smoother gear shifts.

3. DIY or Dealer Service?:

   • Some GX 470 owners choose to perform the fluid change themselves. If you’re comfortable with DIY maintenance, there are helpful tutorials online.
   • Alternatively, you can visit a trusted mechanic or dealership for professional service.

4. Sealed Transmission Systems:

   • The GX 470’s transmission is a sealed system, which means there’s no traditional dipstick for checking fluid levels.
   • To change the fluid, you’ll need to use specialized equipment to drain and refill it through the cooler lines or other access points.

5. Your Mileage:

   • At 60,000 miles, it’s an excellent time to consider a transmission fluid change. Regular maintenance ensures your GX 470 continues to perform reliably.

Did you already check with the dealership. That's where we bought ours, although many years ago.

Your 2009 Lexus IS250 experiencing a black radio screen with functioning sound but unresponsive buttons can be quite frustrating. Let’s explore some potential solutions:

1. Main Circuit Board Replacement:

   • The navigation unit screen in your IS250 might be staying black upon startup, affecting the radio controls and climate control.
   • A common fix for this issue is to replace the main circuit board. This resolves the problem in 99% of cases.
   • If you’re comfortable with DIY repairs, you can consider sourcing a replacement circuit board and installing it yourself. Otherwise, seek professional assistance.

2. Head Unit Assessment:

   • Usually, when a radio stops working, the issue lies with the head unit itself.
   • Since you’ve already replaced fuses related to the head unit, it’s worth checking if the eject button (if applicable) is functioning.
   • If the head unit remains unresponsive, it might indeed be time to consider a new head unit.

3. Resetting the System:

   • Sometimes, a simple system reset can work wonders.
   • Try holding down the audio system power button for about 10 seconds until you see the Lexus logo appear. This indicates that the reboot process has begun.
   • After the reset, observe if the screen responds or if any buttons start working.

4. Professional Diagnosis:

   • If none of the above steps yield results, it’s advisable to consult a professional technician.
   • They can perform a thorough diagnosis to pinpoint the exact issue and recommend the best course of action.

I've never heard of coil springs wearing out, although I suppose that in an area where streets are salted during snowstorms, springs could be weakened by rust. If your car has been used in CA where snow is rare or non-existent, then the springs should be fine. Has your mechanic inspected them?

1. Low Oil Level: A common cause of ticking sounds is insufficient oil. Ensure that your engine has the proper oil level and that it’s clean. Contaminated oil or using the wrong viscosity can also contribute to engine noise¹.

2. Hydraulic Lifters: Tappets (also known as hydraulic lifters) could indeed be the culprit. These components maintain proper valve clearance and can make noise if they’re not functioning correctly. If they’re worn or malfunctioning, you might hear clicking sounds².

3. Exhaust Manifold Gasket Leak: A leaking exhaust manifold gasket can create ticking noises. Inspect the gasket for any signs of damage or leaks.

4. Worn Engine Components: Over time, engine parts can wear out. Worn bearings, pulleys, or other components might cause clicking sounds. Pay attention to whether the noise changes with engine speed.

5. Motor Mounts: Damaged or worn motor mounts can lead to engine movement and cause clicking or knocking sounds. These mounts stabilize the engine and absorb vibrations.

6. Valve Train Issues: Improper lubrication of valve train components can result in ticking noises. Make sure your engine oil is at the correct level and of the right type.

Recommendations:

• Inspect the Oil: Check your oil level and quality. If needed, top up or change the oil.
• Professional Inspection: Consider having a mechanic inspect your engine to identify the exact cause of the noise.
• Listen Carefully: Pay attention to when the noise occurs (e.g., during acceleration, idle, or warm-up). This information can help diagnose the issue.

1. Check the Battery: Ensure that your car battery is fully charged. Sometimes low voltage can cause issues with the door locks. If the battery is fine, proceed to the next steps.

2. Door Lock Actuator: Since you’ve already replaced the passenger door actuator assembly, it’s essential to verify that it’s functioning correctly. The actuator might be faulty or not properly synchronized. Here’s what you can do:

   • Reset the System: Disconnect the car battery for a few minutes and then reconnect it. This can sometimes reset the system.
   • Reprogram the Key Fob: Try reprogramming your key fob. Hold down the lock and unlock buttons simultaneously for a few seconds. Then, press the lock button again. If successful, the locks should cycle once.
   • Inspect the Actuator Wiring: Check the wiring connections to the actuator. Ensure they are secure and not damaged.
   • Test the Manual Lock/Unlock Switch: Use the interior door lock switch on the driver’s side armrest. If it still doesn’t work, proceed to the next step.

3. Common Issues: Since both doors are affected, let’s consider common factors:

   • Central Locking Module: There might be an issue with the central locking module that controls both doors. Unfortunately, this module is usually located inside the door panel. You may need professional assistance to diagnose and fix it.
   • Fuse Check: Verify the door lock fuse. Sometimes a blown fuse can cause erratic behavior. Refer to your car’s manual for the fuse location.
   • Door Lock Settings: Some Lexus models allow you to customize door lock settings. For instance, you can choose whether all doors unlock or only the driver’s door when using the key fob. Check your owner’s manual for instructions on adjusting these settings.

4. Emergency Access:

   • Trunk Release: If you can access the trunk, try using the trunk release button. Sometimes this can unlock all doors.
   • Fuel Door Opener: Look for the fuse box inside the trunk (rear, driver’s side). There’s a red 10 Amp fuse that covers the fuel door opener switch. Check if it’s blown¹.
   • Garage Door Opener Trick: This might sound odd, but some Lexus owners have reported success by using their garage door opener. Here’s how:
     1. Clear any codes in the car (hold buttons 1 and 3 until they blink fast).
     2. Press the car’s open button (#1) and hold it up to a working garage door opener.
     3. Push the learn button on the garage door.
     4. Press and hold the #1 car button until it blinks fast.
     5. Release it and, within 5 seconds, press the #1 car button to see if the garage opens.

5. Professional Help: If none of the above works, consider seeking professional assistance. A certified mechanic or a Lexus dealership can diagnose the issue more accurately.

Remember, patience is key when troubleshooting car problems. Good luck, and I hope you regain access to your car soon! 🚗

$285/hr for a diagnostic... They said they'll probably recommend replacing the TPMS sensors right away and that would be ~$700+ 

Another possible option is a Toyota dealership. I have saved hundreds of dollars by having them service our hybrid which has an identical powertrain as the Toyota highlander of the same era.

Have you tried a Lexus dealership? 

Hello, Parker. Have you searched for a relevant youtube video. You can also be able to find the section of Factory Service Manual. This is what I do in order to determine if the task is something I can complete in a decent amount of time.

Hello, Rick.

Have you checked an OEM parts site such as this one?

2018 Lexus LS500 Parts - LexusPartsNow.com

You may want to stop by a local detailer and ask if they can inspect your car. They should be able to confirm whether or not it had been treated.

Hi, Sandie.

Have you thought about Autotrader.com? Placing an ad in it does cost about $50. I have sold a few cars and some auto parts on craigslist, but I would not recommend going that route if you would be selling the car, yourself. I most recently sold a 2014 Mazda 3 to a woman who brough along her male friend. 

There is also Cars & Bids: Auctions of cool modern cars, trucks, and SUVs (carsandbids.com)

I haven't gone this route but Doug DeMuro, the guy who started this sight, is a San Diego native. He previously worked for Autotrader.com

The issues you’re experiencing with your 2006 Lexus IS250 could be due to a few different factors. Here are some possibilities:

1. Electrical System Issue: The car alarm going off and the car not starting could be due to an electrical system issue. There might be a short in the system, something may not be grounded correctly, or a power wire could be causing this issue¹.

2. Faulty Anti-Theft System: The car’s anti-theft system might be preventing the car from starting. You can try resetting the Anti-Deterrent by using your key. Stand outside of the car and close all doors. Insert the key into the driver side door and turn the key to clockwise and counterclockwise for three to four cycles².

3. Battery Issue: If the battery is not fully charged, it might not have enough power to start the car. You could try jump-starting the car and then driving it for at least 30 minutes to fully charge the battery³. Also check your key pendant's battery if it has one.

4. Faulty EFI or Blown EFI Fuse: If the car still cranks strong but the security light is on, it could be a bad EFI or a blown EFI fuse.

Changing the automatic transmission fluid in a 2007 Lexus ES 350 3.5L V6 involves several steps¹²:

1. Drain the transmission fluid: This is typically done by removing the drain plug located on the transmission pan.

2. Install a new pan gasket and filter (if replaceable): After draining the old fluid, a new gasket and filter are usually installed.

3. Add the proper type and quantity of transmission fluid: The Lexus ES 350 uses Toyota WS ATF¹. The fluid must be added slowly as it will fill up quickly and is difficult to remove excess fluid if you overfill³.

4. Check for leaks: After the new fluid has been added, it’s important to check for any potential leaks.

5. Test drive the vehicle: This helps to ensure that the transmission is functioning properly with the new fluid.

Please note that the Lexus ES 350 has a fill plug and an overflow drain plug on the transaxle. The fluid must be checked via the overflow drain plug with the vehicle running and the fluid temperature must be between 104-113°F¹. This is a pretty complicated procedure that might need to be done by a dealer¹.

The cost for a transmission fluid service for a 2007 Lexus ES350 3.5L V6 in California is estimated to start from $337. This service typically includes the replacement of the pan gasket, filter, and transmission fluid¹. Please note that prices may vary depending on your location and the specific service provider. It’s always a good idea to get a few quotes before making a decision.

Based on your description, it seems like there could be a few potential causes for the lack of power to your interior electronics.

1. Alternator Issues: The alternator plays a crucial role in powering your car’s electrical systems. If the clip on the alternator is broken and it’s not making a proper connection, it could indeed be causing your electrical issues. A damaged alternator can give off inconsistent voltage, which can cause electronic accessories to over- or under-perform.

2. Fuse Box: Even though you’ve checked the main interior power fuses, there might be other fuses that are related to the interior electronics. For instance, there’s a fuse box located where the driver’s left knee on the dash is, and that’s where the named sub-systems get their power. Check the DOME fuse & RADIO fuse⁴.

3. ECU Reset: Sometimes, after replacing certain parts, the car’s ECU (Engine Control Unit) might need to be reset. This can sometimes resolve electrical issues.

Hello, Hugo. Have you checked for codes? How many miles are on your RX?

We have almost 140,000 miles on ours and have never experienced what you describe.

Hello, Joshua.

It would be difficult for me to believe that this is NOT a great deal. Perhaps there were more than a few of this model cars on the lot?

My best guess is that if they are the exact same height, width, offset and tire size, the calipers would clear.

Would the seller return your money if there is an issue? I try to avoid spacers, but many sportscar owners use them with success.

Hello, Robin. Did your dealership check for a Technical Service Bulletin that is described below?

Quote

Lexus released a TSB (Technical Service Bulletin) to address the fourth gen RX 350’s droning problem. Dealers will add a damper or counterweight near the catalytic converter to minimize the harmonic resonance that’s causing the droning and vibration.  Some dealers have even gone as far as replacing the center section of the exhaust.

Many years ago, I noticed scratches on my car's hood. It turns out that the neighbor's cat would climb and it, and when startled by one us, opening the door, the cat would scramble off the hood, trying to get traction with its nails.

There are at least a couple of ways washing a vehicle can cause scratches.
1. If your bucket does not have a dirt strainer, granules of sand can become trapped in a microfiber towel, and subsequently result in scratched in the paint's clear coat.
