I bought 4 kumho tires sized 205 50R17 for this car in September of 2015. In August of 2017, at about 25000 miles on the tires, one of them developed what we later learned was a belt separation. The symptoms were a severe vibration, and severe pull. We replaced two of the tires. 10 months later the car developed exactly the same symptoms, and it was discovered that another of the tires had a belt separation. I replaced all 4 tires with another brand. I called kumho to report the issue, as they clearly had a bad run of tires for me to have to out of one set. The person answering the phone (warranty department) insisted that 'belt separations are common', that the recent recall was a "voluntary recall because the engineers just wanted to see the tires'. I asked to speak to someone in their safety or engineering departments. She said "we don't have anyone like that".

Going down the road and all of a sudden it sounds like a rock banging in the rear driver side wheel well. It turns out to be a broken shock mount. This is the second one that has broken. One broke at ~80,000 miles and now this at ~120000. Search the internet and it is a known problem.

Mazda5 2008 wearing inside of tires prematurely and cupping. Outside edge of tires reported to still have 15000 miles left of use. Second set of tires purchased with same problem. Grinding noise every time dealer rotated and aligned the tires every 5K miles during oil change. I was accused of not rotating tires enough; however, now they admit the alignment is a common problem with Mazda5. Dealer only recommends I get a "special" german engineering style alignment that costs $89 every 10K miles. I am forced to pay for their poor design.

Mazda 5 premature tire wear on toyo tires. The Mazda has 24712 miles, but only ~15000 are on the toyo tires due to running snow tires all winter and there is cupping and inner tire wear. Alignment was checked at Mazda and rear was slightly out of spec (-0.03). Mazda denies ever hearing of a tire problem on their Mazda 5S, when the topic is all over their web. When I purchased the car the saleman assured me Mazda had resolved the premature tire wear that had been seen in the uk where the Mazda 5 appeared before the usa.
