Great. Patience/persistence is the key!

Hello, Dan. Have you looked at a video such as this one?

Yes, after replacing the battery in your 2016 Lexus RX350, you will need to perform a reset to ensure all systems are functioning optimally. Here are the steps to reset your Lexus after replacing the battery: Turn Off the Ignition and Disconnect the Negative Terminal: Before you start, make sure the ignition is turned off. Then, disconnect the negative terminal of the battery1. Wait for 15 Minutes: Allow the vehicle’s systems to reset by waiting for about 15 minutes. Reconnect the Negative Terminal and Turn On the Ignition: After waiting, reconnect the negative terminal and turn on the ignition1. Reset Specific Functions: Follow the on-screen prompts to reset specific functions. This includes resetting the clock and date settings, power windows and sunroof, and the audio and navigation systems. Test the Functionality of Your Lexus After Resetting: After you’ve completed the reset, test the functionality of your Lexus to ensure everything is working properly. Please note that each window has to be reset individually. To do this, start the vehicle and roll each window down and hold for second. Also, all your radio presets will be lost and you will have to re-enter all. If you experience any issues with the functionality of your Lexus after resetting, troubleshooting options are available for common issues during the resetting process. A comprehensive test drive helps identify and address any remaining issues.

Traction control can come in handy under the following conditions: Heavy Rain, Snow, or Icy Conditions: Traction control is essential in situations such as heavy rain, snow, or icy roads, significantly improving safety. It helps prevent your car from losing traction, hydroplaning, or potentially crashing. Navigating Curves in Adverse Weather or Making Sharp Turns on Unstable Surfaces: It proves particularly valuable when navigating curves in adverse weather or making sharp turns on unstable surfaces. Driving on Slippery or Uneven Roads: Traction control should be on for most driving conditions, especially slippery or uneven roads. Sometimes a no-start (no crank) conditions indicates that the starter is failing. If the odometer is broken, how can you know for certain how many miles have been driven?

What year is your RX 350? By the way, I've found that Apple is seldom "state of the art". They still do not have an intelligent stylus. and their photo abilities are almost always a year behind that of Samsung. Perhaps it's good that Toyota/Lexus does not imitate Apple.😏

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? Turn the key to the on position. 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. Repeat this process for all 4 doors Also, you may get lucky in finding a wrecked GX470 at a scrap yard.

The torque specification for the valve cover bolts on a 2004 Lexus RX330 is 9 ft-lbs. However, I couldn’t find the specific tightening order for the rear valve cover bolts in my current resources. You may be able to find an online service manual that should include what you are looking for.

I found this information by running a Bing CoPilot search, given your information:

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.
