  ELECTRICAL SYSTEM:WIRING · TRAILER HITCHES

  Mazda North American Operations (Mazda) is recalling certain 2017 CX-5 vehicles equipped with an accessory trailer hitch wiring harness. This harness may be routed such that there is insufficient clearance between the harness and the exhaust muffler, allowing the wiring harness to contact the muffler.

  Risk: Contact with the muffler may damage the trailer wiring harness, potentially resulting in the trailer lighting being inoperative, thereby increasing the risk of a crash.

  Remedy: Mazda will notify owners, and dealers will reroute the trailer hitch harness away from the muffler, replacing the harness if it is damaged, free of charge. The recall is expected to begin January 20, 2018. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 1617K.

   The radio is uncontrollable by driver. The radio the self dial from Bluetooth. Even if not connected, the radio surprises this driver by playing the radio unexpectedly at the highest rate. Due to the buttons not working, driver cannot turn down the radio causing safety concerns for being scared and distracted. There are no warnings. Mazda is unwilling to assess without pay.

   There is a consistent issue with the “ghost touch“ and the electrical system so when you’re going down the road, the musical will change. The music will blast up or down randomly it’ll get stuck and it’s very distracting. It will hang up on people while you’re having a conversation through the car phone. This was a recall for Mazda 2014 through 2016 and they need to extend it because it was still happening with my 2017. This is my first experience with Mazda and it has not…

   Infotainment system randomly makes its own selections. Turns volume up and down, changes settings, changes stations... etc. Anything that can be controlled on the screen is at risk of being randomly hijacked. Once, my drivers assist volume was unexpectedly turned to full blast and randomly shouted "navigation assistant will be at this volume. " I jumped so badly I actually could have crashed if I hadn't been at a light.

   During a one-hour car ride, the front passenger side seat heater burned a hole through the seat, damaging my wife's skirt and leaving a hole in the upholstery. The overheating definitely originated within the seat. We immediately turned the seat heater off and have not used it since. It could have started a fire, which is very scary, or burned my wife, which is a serious safety risk. This issue has been mentioned by other Mazda owners, but I cannot find any recall reports.…

   The infotainment system suffers from ghost touching. It has gotten out of control even after a “recall” fix at the dealership. Without being touched the volume changes, the stations change, the presets change, the car makes calls to my contacts. I am often unable to control the screen as it turns the car to max volume while driving. It is extremely unsafe, distracting and alarming.

The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably.…

    Twice now, my 2017 Mazda CX-5 stalled on the highway with a check engine light popping up--both times was driving around 60-70mph for a couple of hours and had about a quarter tank of gas left. The first time, no code was found, but the second time, after a deeper diagnostic, the dealership found a P0192 code. After reading here and many other places online, based on the code and the car's behavior, it really sounds like the Denso low-pressure fuel pump is to blame; that's…

    There is a known issue of "Ghost Touching" on the infotainment system on 2017-2020 Mazda's. The ghost touching causes the infotainment center to randomly self-select options on the screen, which is highly distracting. The following are experiences I've had while driving (sometimes going 70MPH on the interstate), where my infotainment center begins to make selections on it's own: Unpausing paused music Making random phone calls Opening text messages and selecting the reply…
