I open the flap door, and can not twist the oil filler cap on my SWB 2014 LS. I dont want to use channel locks, afraid it might break. Has anyone had this problem and have a solution?

There are specific wrenches for this. See Auto Zone, etc. When reinstalling, use a torque wrench adjusted to the proper Lexus torque using the special wrench. Don't over tighten. That's apparently what has happened here.

Thanks for your response. Last oil change was at a Toyota dealer during the pandemic since they were much closer and offered to pick up car from my house. Sounds like they over tightened. Going to Lexus Tuesday. Wonder if Toyota will pay for repair if any is needed.

The caps are extremely difficult to remove. A Lexus tech told me some time ago they never remove them as it's just an unnecessary step. No real reason to other than a little messy if you don't. I do my own oil changes on my '11 and never have over the many times I've changed the filter.

Pop the engine cover off. Try to see if you can spray some penetrating oil like wd40 with a straw preferably around the cap the wait. Then lightly tap with a rubber mallet or something plastic like the handle end of a screwdriver and then try to turn it. Once it is off then take a rag and spay some brake/parts cleaner into it and clean the treads the cap and where it screws in. It wouldn't hurt to buy a new cap. Oem ones appear to be short money online

You may also want to put a glove on. Sometimes just a bit more grip will do the trick.

Good point. Mine has always been quite tight also and I just assumed they were all like that. Anyway, I've always managed to get mine off, even taking both hands at times. I'm not sure a new one would be any better, though, as Lexus probably doesn't want them coming off too easily for obvious reasons. Maybe go to Lexus and try some on new and used LS's before buying a new one.
