   My wife was driving our 2016 Mazda CX-5, and was getting ready to pull into our daughters' driveway. My wife slowed down to a stop before entering the driveway. She gave the vehicle some gas to move forward. She stated that there was a pause, then the vehicle accelerated forward slamming into the garage door and the corner of the garage/house. There was also a Tesla parked inside the garage that was knocked back about a foot and a half. The distance from the edge of driveway…

   The vehicle's air conditioner expansion valve is defective/malfunctioning. While driving the vehicle with the air conditioning operating a loud whooting noise fills the interior of the vehicle. The noise sounds like the siren/hooting sound the police make when they want you to pull over or get out of their way. But the sound is loud and comes from inside the car jarring the driver and passengers. I purchased the car in early 2017 new. I first noticed the AC issue in the…

   I was driving on a city street and slowed to turn right onto a driveway at at a private residence. As my car entered the driveway and near the end of the right turn, my car had a sudden unintended uncontrolled acceleration, continued the turn, went over a low hedge of shrubs on the right side of the driveway, continued down a short rocky incline, and landed on a large rock where the car stopped.

    Catastrophic engine failure. Needs a total engine replacement, regular oil changes. We went to get the oil changed within 1,000 miles of the suggested mileage range and it was “out of oil”. The dealership told us we needed a new engine. It hasn’t been driven and sounds like a helicopter when turned on. We have had regular maintenance on the vehicle, one owner. It started acting up and was trying to stall out on the highway. Then seized up and wouldn’t go over 10mph. It’s…

    My daughter was driving her 2016 CX5 when the coolant temperature warning message displayed on the instrument panel, advising her to pull over immediately. She had just driven on to the expressway, but luckily was still in the right lane and was able to pull over safely. If she had been in any other lane of the busy highway when this occurred it could have been a serious safety issue for my daughter and the other drivers on the highway. I contacted AAA to tow the car to my…
