All 4 of my BH255/50R20 XL 109v NOKIAN WR G4 vehicle tires are exhibiting abnormal tread degradation and excessive sidewall cracking. The tire defect includes a circumferential crack along the top of all 4 tires, where the top of the tire's sidewall and tread base meet. Upon tire inspection, the structural integrity and safety of these tires with continued usage is questionable. The tires in question are only 26 months old and have approximately 31K miles of usage.

The information screen is getting 'spider cracks" spreading across the face and turning opaque making the information unreadable. Mazda is apparently aware of this defect and issued a TSB for earlier models. Dealers were unhelpful and quoted $1000 - $3000 to repair depending on the VIN.

The vehicle will hesitate/stall while driving down the road. The vehicle has done this multiple times and has actually shut off on 2 different occasions while at a stop. on 2 occasions now the vehicle has not wanted to start.

The last time, 6/9/25 they said they suspect fuel pump going bad, but until the vehicle…

Vehicle randomly displays "smart brake system malfunction," "forward smart city brake malfunction" and " front radar system malfunction." This has been going on for at least a year. I will be driving on a highway, trying to accelerate and these messages will pop up. I'm not able to accelerate when these messages pop up and I have to turn on my hazard lights and pull over to the side of the road. The only thing that clears these warnings are for me to completely shut down my car and restart it. Luckily I have been able to get over to the side of the road on the highway without an accident, but these warning lights pop up when it's sunny out and there is no reason for the car to act the way…
