2017 Mazda Mazda6 Complaints

ELECTRICAL SYSTEM — Filed 06/13/2026

The center mounted Mazda Connect infotainment system in my 2017 Mazda 6 Touring sedan is defective. The screen randomly & intermittently changes display modes while the vehicle is on (driving or parked). It began about 2024 & getting worse. One second it will be on navigation then it arbitrarily switchs to phone settings or set a random destination in the navigation screen or change radio channels. the routine is entirely random and is never the same results. There are no dash warning lights, no EWL, no indications of any kind before, during or after. Resetting the infotainment system does not resolve the issue. road conditions or speed do not change the issue. outside temperature seems to affect the unit more because the hotter the ambient temp, the worse the issue seems to be. likewise, high humidity & high temperature causes more issues. The vehicle is garaged in South Florida. removing the SD card from the center console (the navigation maps from Mazda) does not affect the issue. replacing the Mazda navigation SD card does not make any change in the frequency, duration or intensity of the issue. moving the jog dial on the center console will allow interfacing the infotainment system, however, not touching the jog dial still has an issue. The issue is becoming a hazard while driving because the turn-by-turn navigation randomly routes to random destinations and when cancelled, it randomly picks another point of interest and starts all over again. The radio cannot stay on a single frequency, it scans through presets. The issues are distracting and the vehicle is out of factory warranty. The dealership cannot reproduce the issue after 3 separate visits for regular maintenance. The reverse camera (also using the screen) works normal most of the time. I had a single issue where the camera would not turn on while in reverse. disconnecting the main 12v battery reset the camera and it has been working since that isolated issue. (Case No. [XXX] (W.D. Ky) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The infotainment screen is malfunctioning through (i) screen cracking/webbing from the inside and (ii) ghosting, i.e., random system reboots and control changes (including volume increases). The ghosting malfunctions occur when driving and can be incredibly distracting and jarring because they are unexpected and randomly occur. The screen cracking is spreading to nearly half the screen to a point where it is not visible in certain lights. This appears to be a well-known issue for Mazda and the cost to address and repair is in the thousands. Mazda does not seem to be taking any corrective action to address this issue.

Ghost touch screen sudden changes in the volume to the maximum while driving. The Mazda dealership where I bought the car said I would need to pay for it, because the car is not under warranty. Mazda said they would not cover the repair.

Ghost touch concern on infotainment touchscreen, similar/same as SSPB6 which was issued for earlier Mazda3 models and extended to other Mazda models. When car is on and touchscreen is not disabled, it exhibits phantom touches, making it unsafe and unusable as it acts like it is being tapped all across the screen. this is especially dangerous when using the navigation which was nearly a $1000 added cost, as it stops the map from being centered on the car location and moves the viewport around as the phantom touches occur.

The car seat involved is a Nuna RAVA convertible car seat that was sent to the manufacturer solely due to a safety recall. I declined the self-repair recall option and requested that Nuna perform the recall service, which they agreed to. During recall servicing, Nuna inspected the car seat and advised in writing that internal Styrofoam/EPS foam in the headrest was missing or broken and that the car seat is not recommended for continued use and is not safety tested in that condition. Despite determining that the seat is unsafe, Nuna returned the car seat to me without providing a replacement, credit, or other safety remedy. The manufacturer has stated that the damage is unrelated to the recall and has refused to replace the seat, offering only a discount toward purchasing a new car seat. As a result of the recall process, I am left without a usable car seat for my child. The car seat has been inspected by the manufacturer and remains available for inspection upon request. I am requesting assistance with recall compliance, as the recall has resulted in an unusable child safety product with no remedy provided.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 11/26/2025

On a clear lane with the forward car 5 car lengths away with traffic flowing, the Automatic Emergency Braking (AEB) activated slowing my car down from 65mph to 30mph. I deactivated AEB on my exit and changed the AEB distance from “normal” to “near”.

SERVICE BRAKES, HYDRAULIC — Filed 06/15/2025

The part was purchased via Rock auto and installed at home DIY. The vehicle failed to return form "maintenance" mode for the rear parking brake. Took it to a Mazda dealer and they determined the Calipers were both manufactured incorrectly or the "spline gear" in the rear of the caliper that meshes to the Electronic Parking Brake actuator. This caused the parking brake to stay in maintenance mode, making it unusable for parking nor emergency braking, making the vehicle undrivable. It also caused Damage that incurred costs for parts and labor of the vehicle. The vehicle can still be driven and the only way to know its potentially unsafe is the light in the dash for the brake maintenance mode. At this time its unclear if this is the only issue with this part. Jason at Dynamic Friction technical support is investigating.

My sunroof exploded while I was driving on the 405 S freeway. It can be inspected at any time as I haven’t had it repaired or inspected by anyone yet. It happened while I was driving at least 65 mph in the fast lane. It sounded like a gunshot and startled me greatly. Glass flew everywhere and I believe hit cars around me as I heard multiple vehicles honk. This was a very scary and dangerous experience. There were no warnings and I’ve never had any issues with my sunroof. Nothing fell on my vehicle or impacted the glass. Thankfully no one was hurt but this is extremely concerning.
