2024 Lexus RX — ticking noise follows RPM but fades when warm

Log the conditions before you spend. Two 2024 Lexus RXs can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. On “ticking noise follows rpm but fades when,” that was the fork that mattered for me. This is from a 2024 Lexus RX in Baltimore with 26,500 miles. Not gospel, but it saved me a headache. Climate here is different, so treat that as a local data point. Next check is the cheap one I can do in a driveway.

OP update: scanned the 2024 Lexus RX again and still only have the one pending code, no new lights. Might be overthinking it, but I'd rather overthink than overspend.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2024 Lexus RX is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. Not gospel, but it saved me a headache. This is me being the wet blanket on purpose.

Ask what changed right before it started. Move a coil or plug on the 2024 Lexus RX if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. This is from a 2024 Lexus RX in Baltimore with 26,500 miles. Write the result down so the next test isn't a repeat of the last one. I'm keeping receipts and dates in one folder.

Log the conditions before you spend. Loaded-suspension checks on the 2024 Lexus RX catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. On “ticking noise follows rpm but fades when,” that was the fork that mattered for me. This is from a 2024 Lexus RX in Baltimore with 26,500 miles. Write the result down so the next test isn't a repeat of the last one. This is the filter I use when the thread starts repeating itself. Cold start is when I can actually reproduce it.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2024 Lexus RX and see if the fault moves. Don't erase codes until someone who can help has seen them. Post the numbers (or the code) and people can get more specific. I'm keeping receipts and dates in one folder.

I'd want a measurement, not a hunch. Two 2024 Lexus RXs can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. This is from a 2024 Lexus RX in Baltimore with 26,500 miles. Do that first. I refuse to clear codes until someone else sees them.

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 2024 Lexus RX does it — then decide on parts. Don't erase codes until someone who can help has seen them. If you share a photo of the worksheet, easier to sanity-check. I'd rather be boring and correct. Might be overthinking it, but I'd rather overthink than overspend.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2024 Lexus RX and see if the fault moves. That's the branch I'd chase this week. If it doesn't change the out-the-door or the repair estimate, it's noise. That's coming from doing this as an owner, not a shop. I'd rather pay for diagnosis than a second guess-repair.

This is usually cheaper to test than to guess. Move a coil or plug on the 2024 Lexus RX if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. Stop there until you know. Not driving it hard until I know more.
