I just bought a 2019 Lexus RC350 AWD F-Sport a few months back and have already had to do two wheel alignments, both to adjust the front wheels toe adjustments. I live in a City and sure there are potholes but definitely not that many. In comparison, our 2014 Toyota Camry has driven 80,000 miles and has never had to get an alignment.

Two alignments in 4 months is too many, and I'm starting to feel the car pull to the right AGAIN and I just got an alignment done last week. Does this mean there's something more going on with the front axle like the suspension and whatnot?

 

possibly,have your car checked by independent shop for suspension and frame damages

 

Who is doing the alignments? Is it an independent shop or a Lexus dealer? Did you check to see if the car was in an accident before you purchased it?

 

Lexus calls for wheel alignments every 15k.

 

Wheel alignments and wheel alignment checks/inspection are 2 different things. Mine has always checked within spec but no adjustment was needed.
Mine is a '15 AWD and has roughly 76K on the clock.

 

Are you living in Toronto Canada ?
It's not an alignment, it's the Lower Control Arm bushing that makes your tires worn in the front, especially the front passenger right side wheel and it's happened to my RC350 as well but not the IS350 3rd gen, you either replace the LCA bushing with Lexus RCF or RRacing LCA, I replaced mine months ago I put the 2 rear wheels to the front and the worn wheels in the rear, my RC350 straight like an arrow on the highway and it seems to fix the problem so far, I took off the OEM Lower control arm bushings and checked them, mine has cracked in the rubber.
This "Pull Slightly to the right" happens with Toyota Lexus after year 2000+ models Automatic Transmission did not happen to my 1994 Toyota Camry, not the Toyota Solara TRD Supercharged 5speed manual but the Toyota Solara SLE V6 Automatic Trans, happened to my 2010 Lexus IS250 AWD and the 2013 Lexus IS350 2nd gen, i traded in for 3rd Gen IS350 AWD Fsport and did not have this issue, got bored with Lexus IS350, traded in for Lexus RC350 and got this pull to the right issue and inner-outer tires wears....But....
Lexus Toyota in general has a little little of pulling to the right...i don't know about others but I've driven Toyota Lexus for 30 years I felt it.
I just bought a Lexus NX Fsport last week and yes slightly pulled to the right as well my friend says it's my head not the car, and my BMW M35i X series drives straight.

 

I don't have a lot of miles on my '15, but I have never had to get a realignment.

 

My BMW X is straight and BMW Z4 5 speed is straight too, I parked the BMW Z4 lol that small toy.....alignment does help save your tire's life.
