2016 Toyota Highlander

**Nature of Safety Defect Within 13,000 miles of normal mixed highway and light off-road use on a Toyota Highland, one tire developed a sidewall bubble and all four tires exhibited extreme and uneven tread wear—far below the advertised 50,000-mile treadwear warranty. The remaining tread depth on all four tires is already under 2/32" in multiple locations, with severe cupping and feathering that makes the vehicle vibrate violently above 50 mph and causes unpredictable handling, especially in wet & snowconditions. These conditions render the tires objectively dangerous and unfit for continued highway or street use. Manufacturer Response Pirelli warranty claim #2194927 was summarily denied as “impact damage” with no physical inspection. Pirelli has refused any prorated adjustment, replacement, or refund, and has kept possession of the failed tire. On November 17, 2025, Pirelli Consumer Affairs closed the case stating: “Pirelli considers this claim to be closed and will not take any further action regarding the claim or the subject tires.” Request to NHTSA I am asking the National Highway Traffic Safety Administration to open a formal defect investigation into the Pirelli Scorpion All Terrain Plus line for: Premature and excessive tread wear (tires effectively worn out in under 13,000 miles vs. 50,000-mile rating) Widespread reports of sidewall bubbles and sudden structural failures Potential violation of Federal Motor Vehicle Safety Standards relating to tire strength, endurance, and treadwear labeling (49 CFR Part 571.139 and Part 575) These tires present a clear safety hazard—severe uneven wear and structural defects can lead to loss of vehicle control, hydroplaning, or catastrophic blowouts. Hundreds of owners have posted identical failures online in the past 18–24 months. Please investigate this tire model for possible safety recall or enforcement action. I am happy to provide the tires, in

I have taken the vehicle to 4 to 5 wheel alignments within 3 months and 3 different shops after the purchase of the tire. Recently I took the vehicle Big O Tires and they _verified the tires have "Radial Pull" / Tire Conicity due to Manufacturing Defect of the a belt separation within the tire's structure. _The shop also verified that the alignment is performed correctly. I believe those tire are unsafe and they could fail suddenly causing crash.

2016 TOYOTA HIGHLANDER WITH OEM TOYO 245/55R19 OPEN COUNTRY M&S 103T TIRES AT ABOUT 70 MPH ON I95 SOUTH BOARD NEAR BRUNSWICK GA (EXIT 38?) , A LOUD BANG WAS HEARD AND THEN THE BUMPING MADE IT OBVIOUS A TIRE HAD FAILED SO THE VEHICLE WAS STOPPED WELL OF THE ROAD NEAR AN EXIT. THE LOCAL STATE HIGHWAY ASSISTANCE TRUCK (CHAMP) STOPPED AFTER ABOUT 20 MINUTES AND THE TOYOTA RESPONSE SERVICE TRUCK SHOWED UP ABOUT 20 MINUTES LATER - THE TIRE WAS CHANGED AND WE PROCEEDED ON OUR WAY - MANY THANKS TO THE "ROAD RANGER" AND HIS TRUCK AND EXPERTISE!

LEFT REAR TIRE ON OUR 2016 TOYOTA HIGHLANDER BEGIN TO LOOSE AIR WHILE PASSING A SEMI TRUCK ON THE INTERSTATE HIGHWAY. THE TIRE PRESSURE ALARM NOTIFIED THE DRIVER OF TIRE PRESSURE LOSS FOR AN EMERGENCY STOP. UPON A COMPLETE STOP THE TIRE PRESSURE HAD DROPPED ABOUT 85 % OR SO, (NOT FLAT BUT VERY NEAR SO AND COMPLETED THE AIR LOSS WITHIN A SHORT TIME AFTER STOPPING).. WE KNOW THIS BECAUSE I WAS FOLLOWING BEHIND MY WIFE DRIVING THE HIGHLANDER AT THE TIME. TRAVEL SPEED WAS BETWEEN 65 AND 70 MPH AT THE TIME. THE TIRES ARE THE ORIGINAL THAT CAME ON THE TOYOTA NEW AND HAD ABOUT 27000 MILES ON THEM. UPON INSPECTION OF THE TIRE IT LOOKS OBVIOUS THAT THE TIRE WAS DEFECTIVE DUE TO THE SUBSTANTIAL AMOUNT OF VISUAL CRUMBLED RUBBER ALL INSIDE THE TIRE SEPARATED FROM THE SIDEWALLS IN SIDE AND THE MASSIVE BLISTERS ON THE OUTSIDE OF THE TIRE, WE HAD ALL THE TIRES REPLACED ON THE VEHICLE AS WE HAD NO TRUST IN THE REST OF THE TIRES AFTER THIS HAPPENED. NEITHER THE TOYO TIRE MANUFACTURER REP., THE LOCAL TOYOTA DEALERSHIP, OR THE TOYOTA COMPANY WOULD TAKE RESPONSIBILITY FOR THE FAILURE, OR OFFERED ANY CONCESSIONS AGAINST THE REPLACEMENT TIRES. PHOTOS OF THE TIRE AND OR THE TIRE ITSELF IS AVAILABLE FOR NHTSA IF THERE IS A REQUEST TO REVIEW. POOR CUSTOMER SERVICE FROM THE TOYO TIRE MANUFACTURER, THE LOCAL DEALERSHIP OR THE TOYOTA COMPANY IS QUITE OBVIOUS TO US THAT THEY HAD NO CONCERN FOR OTHER PEOPLE THAT MAY HAVE THE SAME TOYO TIRES THAT TOYOTA CHOOSE TO PUT ON THE NEW VEHICLE THAT MAY CAUSE AN ACCIDENT. THE TIRE BRAND IS TOYO, TIRE LINE IS OPEN COUNTRY, TIRE SIZE 245-55-19 DOT # 73HH (CND2216)
