2014 Mazda MAZDA6: adaptive cruise control problems

Filed Apr 17, 2019 · Brakes · 65,000 miles · MD

A year ago I took my car for a recall that had to do with the handbrake somehow rusting out where it sits in the rear brake calipers. They inspected the calipers and told me they had to order parts. I never received a call. The next time I went back I asked about it and they said it was fix. After the visit they recommended to replace the rear brake calipers. The vehicle is a manual and is to the point where the hand brake does not work at all. It runs the risk of rolling away if the transmission fails or it comes out of gear. It is clearly stated in the federal safety agency #17v‑393 and I have called mazda corporate who told me it doesn't have to do with the calipers ("your mazda dealer will check the parking brake actuator shafts inside the left and right rear brake calipers."). Mazda reference number [xxx]. Also because of the rust the handbrake is lose so if you use cruise control the handle can accidental pull up enough to ignite the handbrake light and make the car automatically turn off cruise control which is surprising and could cause the driver to crash.

Intermittently, the cruise control buttons do not perform their proper function. When experiencing the issue, all of the following occur: 1) cancel button functions as the minus (decelerate) button, 2) the minus button functions as the plus (accelerate) button, 3) the plus button doesn't work, and 4) the off button disengages the cruise control but does not shutoff the cruise control main power. This behavior is an issue because with the cancel button acting as the minus button, the cruise control will activate with the cancel button. In addition, having the minus button function as the plus button could cause an accident if the car behaves in the opposite manner as expected. The issue occurs intermittently while driving.

Fow (forward obstruction warning) inspection required flashes on dash as if a loose connection. Only flashes for about 3 seconds then goes away. I manually turned off fow to stop the flashing. But will turn back on once I restart the car. The cruise control off/on switch seems to affect the warning flashes as well. Once the car warms up, things seem normal. During driving this effects the cruise control and system overall. Happens every time I start the car and start driving

I was driving on the highway with my cruise control set and all of a sudden the cruise control shut off and a warning popped up "mrcc inspection required"

My 2014 mazda 6 has 68000 miles. Within the last few weeks while driving going 55 around corners, has had a "power steering malfunction" light pop up and the steering totally locks up for a few seconds causing me to nearly hit multiple cars. I believe my issue has to do with something electrical that I had checked on my car at 34000 miles right before the warranty was up. My car has a radar that performs for radar cruise control and smart city braking, I got many messages saying that the radar isn't working and that it needs inspections. I brought it in at 34000 miles and they reset something so the car wouldn't show the message and told me it was fixed, I then started doing this after the warranty ended and I figured it wasn't a safety issue so I didn't fight it. Now I believe that the same issue that causes this light to come on is what is causing the steering to lock up because as the steering locks up the radar inspection light also turns on. So now that they didn't fix it when I brought it in the first place, I am having safety issues and they won't do anything about it even though I tried to get it fixed earlier on. Now they are going to charge me $170 just to diagnose the problem, then the price it cost for labor and parts to fix it when I go in, this is ridiculous because I tried to fix it under warranty and they did nothing. Now I'm a hazard to me and many others on the road because my steering is locking up on a 3 year old car with only 68000 miles. That should not happen.

While driving on the highway with cruise control on, my car atomatically slammed on the brakes and slowed down rapidly. A short time later, the forward obstruction warning indicator came on and said an inspection was needed. Mazda dealership said "never heard of that" despite similar public comments on user forums. Dealer will not cover full cost of the repair becuase care it out of warranty. I believe this is a serious safety issue that should not fall under normal warranty considerations.
