There are 5 owner-reported suspension complaints for the 2015 Toyota Siennain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The front tires are wearing out to an unsafe tread in under 15000 miles due to the suspension in the front of this vehicle. If people are not vigilant the tires become unsafe quickly due to poor engineering on the front end.
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.
PURCHASED MY SIENNA IN FEBRUARY, 2019 WITH 41K MILES. DAYS AFTER PURCHASE, I BROUGHT A NOISE TO THE DEALERSHIPS ATTENTION AND WAS TOLD IT WAS ROAD NOISE. FAST FORWARD TO JUNE, 2019 AND THE NOISE IS WORSE. MY DRIVER'S SIDE STRUT IS BLOWN AT 44K MILES. FINDING A REPLACEMENT HAS BEEN A HASSLE. THIS PART IS OBVIOUSLY A MANUFACTURER DEFECT AND SHOULD BE COVERED BY TOYOTA FOR REPLACEMENT. CURRENTLY WAITING AND HOPING THE BACKORDERED STRUTS SHIP TO ME SO I CAN GET IT REPLACED. ALSO, DEALERSHIP RECOMMENDED REPLACING ONE STRUT. COMMON SENSE DICTATES THAT YOU ALWAYS REPLACE STRUTS IN PAIRS, OTHERWISE YOU WILL DRIVE A LOPSIDED VEHICLE AND CAUSE MORE TROUBLE DOWN THE ROAD.
I AM A DISABLED FEDERAL EMPLOYEE. I HAVE A NEW HANDICAP CONVERSION VAN FROM VMI VANTAGE MOBILITY INT. IT IS NOT SAFE TO DRIVE. THE SUSPENSION IS HORRIBLE
