Open the full vehicle complaint log (all categories)Back up cameras fail infotainment system reboots and maps on the system inadvertently counts stops plus changes volume at loudspeaker telling me “this is the level “ and is on highest volume. Which you can’t turn down. All are dangerously interfering with driving. Please put pressure on Mazda to fix and not just update software when the problem has been fixed called CMU
The infotainment system on the Mazda consistently glitches causing vehicle settings to be changed while the vehicle is in motion or stopped. The volume changes, navigation settings change, maintenance settings change including door settings and any setting that can be controlled by the touch screen. If a phone is connected to the system it will make calls and stop volume on system. Additionally, when reversing and the back up camera is enabled/used the screen glitches and you can no longer see a large portion of the rear view - making it a very large safety hazard. There are thousands of people who report this and little has been done for years other than people being charged for an entire replacement and the issue just comes back. Please see duffy v. Mazda, filed this year. There has also been another Mazda model where the infotainment was identified by nhtsa to be faulty - the repair period was extended 7 years but has been expired for years now - it has not covered any of the CX models. Dealers are very aware of this.
The center display on it own ( ghosting) changes setting randomly this impacts safety information displayed including rear camera, and distracts the driver. The cause is a defectinve digitizer on the LCD screen panel. The 2016 model year of the same car Mazda CX-5 has a simalar problem and was recalled There is no warning prior to these occurances
Multiple instances of phantom braking, which resulted in two instances where we were just inches from being rear-ended. The circumstances of the phantom braking are similar, and has occured many times. CIRCUMSTANCES OF PHANTOM BRAKING are as follows: vehicle in front in lane makes right hand turn from lane (with or without turn signal or braking). The vehicle in front typically has exited the lane, and the Mazda emergency brakes hard! Variable vehicle acceleration/deceleration dynamics factors: the Mazda could be coasting, decelerating with brake litely applied, accelerating in lane (because vehicle has fully exited lane), accelerating and exiting lane (go around turning vehicle). Variable turning vehicle rear lights (signals, brake lights) factors: the turning vehicles can be braking or not, turning with or without signaling- it does not matter. The Mazda will brake hard regardless. This may be an extension of the same: when traveling on an Interstate Highway, nominally at the posted speed. When a faster vehicle safely accelerates into the Mazda’s lane, the Mazda will brake hard. The Mazda does not recognize that the vehicle entering the Mazda lane is accelerating, nor does the Mazda seem to understand (anthropomorphism) the context (dynamics) of the situation (accelerating merging traffic). Hard braking in these circumstances has resulted in several near misses being rear-ended. The request for DATE below should be “NA”, because the phantom braking has happened many times.
Was driving at low speed and out of nowhere the warning lights came on , smart city , abs, among others. It's caused by this vehicles front facing camera and or front radar emblem malfunctioning causing the vehicle to slow down , low power , and steering wheel jerking making mechanical sounds. There's a tsb as well.
Automatic Emergency Brake comes on at random. Driving at medium speed, no cars in view, car brakes and dashboard displays EMERGENCY BRAKE. Has not yet been inspected by a dealer because car is out of warranty. 2018 Mazda CX5 with only 19,000 total miles driven.
UNKNOWN My vehicle stalls while I’m driving. My RPM tends to stay at one number when this happens. I was nearly struck by a vehicle while trying to merge onto the highway. This is very dangerous. There’s also I light that comes on my dashboard that seems to be indicating an accident or something of that sort.
I find I have to put my foot down on the gas pedal to the floor to make it literally go at times. Ive heard this cloaking noise several times like its getting ready to conk out. The brakes seems to me don't stop as they should at times I have to go in hard on the brake pedal. The air conditioner does not blow cold an see where previous owner had same issue 2 yrs straight from looking the the service invoices that was left in the truck. The sensor detection does not always work to let me know car/person is around. Coleman Taylor Transmission informed me that this thing does have a issue, the rpm are not as they should be. When I took it back to Kia Gossett about the brakes the used mgr drove it made it seems there were no issues as well as Norcross Mazda. Previous owner invoice show brakes were a concern as well. Had I known there was a prior recall on the PCM I would never bought this JUNK!
