“A chip in the windshield cracked and spidered down the whole windshield. It happened 2 weeks after owning my new car. I'm still unsure on why it cracked 🤦‍♀️ there isn't a chip mark or any start point. It's worried how it just started cracking. And since it's over a 1,000 to fix it. It is still cracked. And anything that requires the eye no longer works. I love my car but hate how nothing needing the eye works.”

“When applying brakes to 2020 Subaru Ascent limited (10,325 miles) the car shudders. Being an aircraft mechanic for over 45 years I knew the brake rotors were warped. I Took car to Subaru of Kennesaw GA. 7-13-2021. They opened work order SuCS159697. They resurfaced the rotors on front brakes and installed new pads. My safety concern is if brake rotor originally installed are warping and now you are removing the width of the rotor making it thinner and more likely to heat and warp sooner. …”
