The failure pattern owners describe
The dominant complaint in this cluster is the ignition refusing to turn off. When owners put the vehicle in park and press the start/stop button, the engine shuts down but the electrical system stays live—radio, dashboard lights, and climate controls remain on, doors won't lock, and the battery drains. Owners must restart the car, jiggle the shifter in and out of park (sometimes 5 to 15+ times), and retry the shutdown sequence to finally kill the power. Some report this happens nearly every time they park; others say it's intermittent.
Mazda issued Service Bulletin 05-004/16 identifying a worn AT shifter switch unit (part KDY0-46-040) as the culprit and released improved service parts. Dealers charge $150 to $600-plus for diagnosis and repair. However, no recall has been issued despite widespread complaints online and dealer acknowledgment that they see this frequently.
A smaller but serious subset reports the vehicle stalling unexpectedly during driving—sudden power loss, check engine light, and traction control lights coming on—with P0301 misfire codes. One owner's dealer replaced the fuel injector, crank pulley, belts, and battery without fixing it; Mazda customer support told the owner the issue is software-related with no release date.
One owner experienced catastrophic electrical failure with loss of brakes, steering, and gauges while driving, along with battery drain that wouldn't start the vehicle after sitting overnight. That case ended in a manufacturer repurchase order from a BBB arbitrator.

Failure modes owners describe
Ignition fails to turn off completely; accessory power remains active
When the vehicle is placed in park and the start/stop button is pressed, the engine shuts off but the ignition remains in accessory mode. Electrical components (radio, dashboard lights, climate control) remain operational. The vehicle cannot be locked and the battery drains. Owners must restart the vehicle, manipulate the gear shifter, and retry the shutdown sequence multiple times—sometimes 5–15+ attempts—before full power-down occurs.
When: Upon shutdown while in park; most common on early model years; some owners report temperature-dependent behavior (hot weather)
Symptoms owners cite: Engine shuts down but radio/lights remain on; Dashboard warning message states 'shift to park' despite vehicle being in park; Doors will not lock; Beeping/audible alarm continues; Requires multiple restart-and-shift cycles to power down completely; Intermittent; sometimes requires aggressive shifter manipulation or driving the vehicle before retry; Battery drains if vehicle left unattended in this state
Repairs/costs cited: Mazda Service Bulletin 05-004/16 (dated 12/22/15 and 4/11/16) addresses worn AT shifter switch unit (part number KDY0-46-040). Replacement switch units with improved wear-resistant material available as service parts. Dealers charged $340–$600+ for diagnosis and repair; some owners report dealers initially unfamiliar with issue or recommending full shifter mechanism replacement instead of switch unit replacement. Bulletin states vehicles produced after 12/27/2013 should have modified switch unit from factory.
Recalls/TSBs owners mention: Mazda issued Service Bulletin 05-004/16 acknowledging the defect is caused by worn switch unit material and establishing improved service parts. No nationwide recall issued. Mazda customer service line: 1-800-222-5500. Some dealers claimed Mazda refused to authorize repair under warranty; one owner received case number 1-4272020134 with no recall/warranty action. Another owner received BBB Auto Line arbitration ordering vehicle repurchase due to broader electrical failures stemming from this issue.
Shifter sensor fails to detect park position
The transmission position sensor (shifter switch) does not properly recognize when the vehicle is in park mode. The engine shuts down but the vehicle behaves as if still in drive, leaving electrical systems active and preventing safe shutdown or locking.
When: Upon attempting to turn off vehicle while in park; can occur intermittently or become chronic over time
Symptoms owners cite: Dashboard displays 'shift to park' warning even though shifter is in park position; Ignition cannot be turned off; Electrical systems remain powered; Doors cannot be locked; Vehicle cannot be safely left unattended; Workaround: aggressive shifter manipulation (pushing toward steering wheel, cycling in and out of park)
Repairs/costs cited: Independent mechanic and online resources identify faulty transmission position sensor as root cause (part KDY0-46-040). Repair involves replacing the shifter switch unit. Owners report $150–$600+ in dealer diagnostic and repair costs. Some dealers unfamiliar with the issue; others confirmed to mechanics that they see this frequently.
Recalls/TSBs owners mention: Mazda acknowledged the defect in Service Bulletin 05-004/16 and identified the worn switch unit as the cause. Improved service parts released. No recall issued despite widespread complaints. One dealer confirmed 'Mazda knows the problem, software related' but provided no release date for fix.
Engine stalls and loses power during acceleration with multiple warning lights
While driving, typically during acceleration or after releasing the gas pedal, the engine suddenly loses power or stalls. Multiple warning lights illuminate (check engine, traction control, TPMS). The vehicle may sound like it is running on fewer cylinders. Vehicle becomes unresponsive to throttle input and feels like it will shut off. After powering the vehicle off and restarting, it typically operates normally again.
When: At 33,000 miles; occurred on highway at 80 mph after releasing gas pedal; happened intermittently over several weeks with repeated episodes
Symptoms owners cite: Sudden loss of engine power during acceleration; Check engine light illuminates; Traction control light comes on; TPMS warning activates; Engine sounds like it's running on 3 cylinders; Vehicle unresponsive to throttle; Shutdown and restart clears symptoms temporarily; P0301 diagnostic code (cylinder 1 misfire)
Codes mentioned: P0301
Repairs/costs cited: Dealer initially blamed aftermarket K&N air filter (owner disputed; filter had been in use for 20,000 miles with no issues on another vehicle). Subsequent dealer visits resulted in replacement of fuel injector (ineffective), crank pulley, belts, and battery. Problem recurred within days of pickup. Owner states Mazda customer support indicated the issue is 'software related' with no release date provided.
Recalls/TSBs owners mention: Owner established case number with Mazda customer support. Dealer claimed Mazda wanted to replicate issue with a technician but was unable to resolve it despite multiple diagnostic scans showing P0301 code. Dealer service manager stated Mazda acknowledged the problem is software-related but had not issued a fix. No recall or TSB cited.
Battery drains due to continuous parasitic electrical load
Battery becomes completely depleted and unable to start the vehicle despite no obvious electrical components left on. Independent testing indicates irregular electrical activity and possible internal alternator or body control module failure creating a continuous parasitic drain.
When: After vehicle sits undriven for more than one day; issues escalated over time
Symptoms owners cite: Vehicle fails to start after sitting undriven overnight; Battery drain with no visible electrical load; Intermittent electrical failures including brake system, steering, gauges, and complete electrical shutdown while driving; Check engine light and other warning lights illuminate; Loss of power steering; ABS failure; Gauge cluster failure
Codes mentioned: U0121, P0500, P0685
Repairs/costs cited: Battery replaced twice by dealer with no resolution. Independent technical specialist diagnosed irregular electrical activity and suspected internal alternator defect and/or body control module failure. Vehicle ultimately rendered inoperable. Repair parts unavailable at local dealers.
Recalls/TSBs owners mention: Manufacturer ordered by BBB Auto Line arbitrator to repurchase the vehicle due to the severity and unresolved nature of the electrical failure.
Start/stop button illuminates amber instead of green; keyless entry recognition failure
The start/stop button flashes or remains amber instead of the normal green illumination, indicating a sensor malfunction in keyless entry recognition. Dealer replaced keyless entry fob batteries without resolving the issue. Temporary workaround is disconnecting the vehicle's negative battery terminal to reset the computer, but the issue returns after 3–4 days.
When: Intermittent; recurs every 3–4 days after reset workaround
Symptoms owners cite: Start/stop button flashes amber instead of green; Keyless entry not recognized by vehicle; Problem persists after keyless fob battery replacement
Repairs/costs cited: Dealer recommended replacing keyless entry fob batteries, which did not resolve the issue. Workaround discovered on Mazda forums: disconnect negative battery terminal for one minute to reset computer; restores green illumination for 3–4 days before recurrence.
Recalls/TSBs owners mention: No official acknowledgment or fix provided.
Multiple warning lights and loss of communication between vehicle systems
Dashboard warning lights illuminate en masse and remain on. When certain controls (such as right turn signal) are activated, the entire electrical system experiences loss of communication, causing engine shutdown and loss of multiple vehicle systems while driving. Diagnostic codes indicate widespread communication failures across the CAN bus network.
When: Occurred without prior warning; triggered by turn signal activation while driving
Symptoms owners cite: All or most dashboard warning lights illuminate; Right turn signal triggers rapid flashing and complete electrical system shutdown; Engine cuts off while driving; Loss of power steering; ABS failure; Speed monitoring loss; Tire pressure monitoring loss; Blind spot monitoring loss; Horn inoperative; Loss of navigation and Bluetooth; Codes indicate loss of communication between modules
Codes mentioned: U0121, P0500, P0685
Repairs/costs cited: Dealer unable to diagnose after 2 hours of work; indicated extended diagnostics and further labor costs needed. Online resources suggest faulty ground wire; however, repair not completed.
Recalls/TSBs owners mention: No response documented. Dealer unable or unwilling to pursue diagnosis.

Pressing the push-start button does not shut off vehicle. Car is in park. Have had to walk away with car still "on", draining the battery.
The car's electrical system doesn't fully turn off after being put in park and turning the ignition off. The electrical system stays on, despite the engine and ignition turned off. It's a BIG problem that I've seen a lot of other people report. And yet Mazda refuses to address the issue.
When the car is stationary and in park the engine doesn't completely shut down, the radio anddash lights stay on. Also the doors do not lock because the car will beep consistentlyand I fear the battery may die. I have to move the car in and out of park and then move the gear shift left and right quickly multiple times and then maybe it will cut offcompletely. Sometimes it takes me up to 10…
A sensor that communicates what gear the vehicle is in is faulty. The vehicle therefore will not turn off completely. The sensor does not recognize that the vehicle is in park. The auxiliary panel remains on, and the vehicle battery will drain. Repeated restating and shifting in and out of gear will finally get the vehicle turned off. This process sometimes takes several minutes. This issue could…
