The Problem

Many 2014 Mazda 6 owners have reported an issue where the radio won't turn off after shutting down the vehicle. This problem is not unique to the Mazda 6 and also affects some 2013-2014 Mazda CX-5 models. When the ignition is switched off, the radio and other accessories may remain on, potentially draining the car's battery.

Root Cause

The main culprit behind this issue is the park position sensor, also known as the shifter switch. Over time, the rubber component at the end of this switch can become too soft, preventing it from fully engaging when the car is put in park. As a result, the vehicle's computer doesn't recognize that the car is in park, causing it to keep certain systems active.

Temporary Fix

If you're experiencing this issue, there's a quick workaround you can try:

  • Put the car in park
  • Turn off the ignition
  • Wiggle the shifter left and right a few times
  • Press the start/stop button again (without pressing the brake pedal)

This temporary solution may allow the car to shut off completely, but it's not a permanent fix.

Permanent Solution

To resolve this issue permanently, you'll need to replace or repair the faulty park position sensor. Here are the steps:

1. Remove the center console to access the shifter mechanism

2. Locate the park position sensor (shifter switch)

3. Remove the switch assembly

4. Either replace the entire switch or reinforce the rubber component

DIY Repair Option

For those comfortable with car repairs, you can try reinforcing the rubber component:

  • Cut a thin piece of plastic to the size of the rubber piece
  • Fold it around the rubber
  • Carefully super glue it over the top, ensuring you only cover the soft rubber portion

Professional Repair

If you're not comfortable performing this repair yourself, it's best to take your vehicle to a Mazda dealership or a qualified mechanic. They can replace the entire switch assembly, which should resolve the issue.

Prevention

Unfortunately, this seems to be a design flaw in certain Mazda models. The best prevention is to address the issue as soon as you notice it to avoid potential battery drain or other electrical problems.
