“My car has 28330 miles. I bought the car two years ago. Last week I was park in from of my house. In the morning, I got in the car and my steering wheel doesn't turn. I took it to Mazda and they want to charge me $3200 to fix this. They won't tell my what happen other than I need a new steering racks. I barely drive this car, never rough, alway service it. This car is too new to have this problem. Mazda will not even try to help me. This car is my lifeline.”

“The infotainment system computer is on constant reboot loop. At first it would only occur when weather was very cold or hot. Then it started happening at least 75% of the time no matter the weather. I had Mazda dealership look at it prior to full warranty running out, they couldn't find an origin of issue and simply checked for software updates. It started happening more frequently and past full warranty so cant get looked at or diagnosed for free. A recall for the infotainment screen was notified to me and replaced at dealership but did not resolve the issue. …”

“6/18/19 6:45 am: my car 'stalled' or lost power as I was accelerating and turning left across a boulevard (us 51 hwy in mcfarland, wi). Luckily, I was able to pull over and came to a complete stop, put the car in park, turned off the car (even though I had no power), waited a few seconds and restarted it. There were a lot of dash warning lights triggered once I lost power, but I do not recall specifically which ones. I resumed driving and have not had a problem since. However, I did find out later (july 10, 2019) that my car could be under NHTSA recall no. …”

NHTSA complaint #11241074, filed 2019-08, 18,000 miles

“My car started shaking and I lost control of the steering. I pulled over as best I could and called a tow truck. The dealership says that rats have chewed through the engine harness and other wiring. They say they have seen dozens of cases in brooklyn and queens just like this. They said that rats are attracted to the coating on the wires. Mazda won't issue a recall or repair the wiring. It is a fire hazard and dangerous to drive. I guess they are waiting for someone to be injured or die before they fix it? My car is 18 months old with 7,062 miles. …”
