Straight to the point, I backed the vehicle up, pushed the brake peddle in and shifted into park. The engine begun to increase in RPMs and I could hear the engine load increase, maybe about 2,000 to 5,000 rpms higher than idle or first start building vacuum idle, as if I was pushing on the accelerator. I literally looked down at the peddles, as I was just doing a quick spot change in my driveway, the accelerator did not appear to be stuck or in contact with the aftermarket winter weather plastic floor mat. I decompressed the brake peddle again and shifted the car from P to D and the engine went to its normal baseline idling RPMs and sound. I put it back in P and turned it off, no issue. I have noticed this problem before, but I only noticed it during this past winter season and blamed it on my winter boots and/or myself instead of the vehicle. I am going to guess this has happened in total about 4 times, including the most recent incident that I just wrote about. The CX-5 is connected to Mazda’s network/ data service or whatever it is called, because I like my cars clock to maintain correct time, which it won’t or can’t do if I prefer my privacy from Mazda. So Mazda should be able to see what happened on their end. It happened in the late afternoon to early evening. I do also use ‘auto hold’ daily and cruise control w/out radar active.
