Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I purchased a set of 4 Michelin defender xt tires for my 2011 Prius II from costco on 11/29/2013. The tires are marketed by Michelin as llr (low rolling resistance) tires. However upon installing them and operating the vehicle for nearly 1000 miles, I found the mpg to be nearly 10 mpg. Less than the oem tires that these replaced. The rolling resistance of these tires are high. Vehicle almost feels like being driven over sand. As soon as I take my foot off the accelerator, the vehicle decelerates rapidly, much faster than the oem tires. I checked the tire pressure, alignment, and wheel bearings, all are within specs. It appears to me that the hysteresis losses in this tire material are fairly high. This tire should not be sold as a low rolling resistance tire. It is being falsely advertised as having this capability to increase sales. The mpg difference was measured by calculating the true miles from my gps unit and dividing the result by the gallons to full at the same pump. This was done three times to accurately access the true mpg difference. No other factors on the vehicle has been changed. Only change has been replacement of the tires.

Was driving a 2011 Prius with just under 25,000 miles on October 18, 2012 on a 2 lane highway. A rear tire sidewall blew out. There was a rollover end for end down a very steep and long ditch. There were severe back injuries.

On October 18,2012 I was driving my 2011 Prius 2 on a 2 lane highway at 55 mph when the drivers side rear yokohama tire blew out on the sidewall. I swerved in to the left lane twice before leaving the road, snapping off a utility pole, going down a revine and rolling over end for end and side to side. I ended up in the middle of the back seat on my stomach facing the rear of the car. The drivers seat was broken back and my seatbelt was still on. I was in in the hospital for a month following back surgery. I had 3 cracked vertibre and one cracked rib as well as many bruises. Needless to say the car was totaled and I am still recovering 3.5 months later.

I was driving on the 101 N freeway at about 55 mph and I heard a loud popping noise. I had never had a tire blow before so I didn't even realize what was happening until I heard the flat tire. Luckily it was my left rear tire so I was not injured and I was able to safely make my way across the freeway onto the right hand side of the freeway where I called aaa to come and change it to my spare. I called Toyota, they said they had nothing to do with the tires and could not help me and I would have to make a complaint to yokohama, the tire company. I called the tire company, they told me to have it inspected and it was found that it was a road condition that led to the tire damage and therefore it was not under warranty. The exact same incident occurred again on 01/15/2013, this time I was going 65 mph on the 101 S freeway. My rear right tire blew out and I had to get across traffic where I got off the freeway and was able to call for help. My concern is not whether the tire company will be able to foot the cost, but the fact that my tires will blow out when I'm driving under or about the speed limit for a road condition that everyone else manages to drive on with no problems. I reported both incidents with Toyota and yokohama.

Since I purchased a 2011 Toyota Prius in December 2011 I have had to replace 2 irreparable original equipment yokohama avis S33 tires due to side wall damage. I am concerned that the side walls are not strong enough to resist potential hazards. This is part of yokohama case #[xxx] which included other concerns. I have rarely had a sidewall problem and never a flat tire with new tires. The first occurred at about 300 miles of use the next at 8300 miles, the approximate incident date.

When you go over a bump in the road at a slow speed the tire slips slightly on the road bed. Yokohama representative says they have had no complaints (telephone conversation, 5/9/12, part of their case #[xxx]). I found the tire is the problem while searching online comments about the tire. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
