CX-5 TR 2.5L 4

  • Automatic transmission

I came to a complete stop about 14 feet from someone. We were waiting to merge from an off-ramp. Both of us completely stopped, my foot on the brake, the engine revved up. It was a pretty full sounding rev. I pushed the brake harder, looked at my dashboard. The car beeped to BRAKE! (said BRAKE!), a notification of Front Sensor failure flashed. Brake, floored to the ground, confused and scared in this very quick moment, the car revving, jolted forward into the rear-end of this guy, and then, only after impact, I felt like I had control again. We were both so confused, him, because he saw me already behind him, fully stopped, and myself, because what the heck just happened!?

I went to the dealership a few days after. They thought I was crazy, but they did look it over and replaced the infotainment console, and the front sensor because it was over-heating.

Before this problem happened with the revving, the infotainment system would constantly change radio stations, mute calls, just odd stuff while we were driving. It would even change brightness modes.

Anyways, yes, my car engine revved from a complete stop, and I felt like I had no control over the situation. Luckily, it was very minor, and no one was hurt.

When this car starts up everyday it over revs itself - sounds like a lawn mower running - ticking loudly, rattling, knocking just excessive engine noise. When I start my car everyone looks over at me and is like what is wrong with your new car. Mazda says it's normal - that is just how Mazdas sound it's ok it will quiet down. It is not ok , when an engine is making all that noise it is because somethings not right. New cars just don't sound like this. I bought a new car so I would not have to deal with this kind of thing.

Mazda is trying to say it is some accelerated warm up system - like they put it on the car to help it warm up. It doesn't help it at all if anything it is damaging it that is why it is screaming and making all the noise. It is some other defect that is internal so nobody can see what the problem is until you take it all apart, but trust and believe Mazda knows what the problem is already. They won't sign their stain on this either because then they would have to recall and fix all these vehicles. Mazda does not make vehicle to last - they make throw away cars because they think that people will actually buy another Mazda !!
