NHTSA Complaint #11430201 — 2015 TOYOTA SIENNA

I have a 2015 Toyota Sienna LE that I purchased new from the dealer. The original Michelin tires had excessive wear after less than 2yrs and ~28K miles. I replaced these with Continental tires(rated for 70K miles) and after 2years and at ~63K on the vehicle miles I had to replace those with General Altimax (rated for 75K miles). Each time tires were replaced it received and alignment. I now need to replace the third set of tires at ~88k for set number four. Additionally I had to replace the Rank and Pinion (Complete unit), both tie rods and both suspension control arms and ball joint assembly and a wheel alignment. Can is adult driven mostly in town but has one long road trip on it (6K miles). This will be the fourth set of tires on a vehicle with less than 100K miles along with 5-6 alignments. All tires have been maintained and rotated. This has to be a vehicle defect as I have multiple tire manufactures, all rated for more than double the tire life I'm getting. I have $2000 in tires so far (not counting the originals) $1250 in replacing the front end components noted and now have to spend another $1k on tires.
