Recently reported ELECTRICAL SYSTEM problems on 2015 Mazda Mazda3

Infotainment system restarts 3 to 5 times, when first starting car, when temperatures in unheated garage are below 50 degrees. i drive four to eight miles, with heater on, before it stops restarting. have taken to dealer 3 times, while under warranty. all they do is reboot it. now the car is no longer under warranty and i refuse to take it back, and be changed for something that should have been fixed the first time. this just might be a deal breaker in buying a mazda as my next car. very annoying.

Takata recall the infotainment system is going haywire, making ghosts selections such as calling ppl, self selecting settings and all other buttons at random times during driving which has become extremely distracting and dangerous to drive the car with this issue. this is apparently a known issue to mazda but they refuse to fix it. all they will offer is swapping it for another infotainment system that will eventually do the same thing again at the customers expense. this takes place while the car is traveling at 5mph or less so it most frequently happens when i am slowing to take turns or traveling in my neighborhood and while at a stop at random times. i have no control over the system once it starts glitching and making calls and changing settings or dialing numbers, i cant hang up im forced to disconnect the bluetooth from the phone but that only prevents it from making calls it still continues to go to the setting at press random buttons

Corrosion of the battery terminal and battery wiring harness preventing car from starting.

When pushing start button all lights go on but car won't start. stationary in drive way

Electrical malfunction in the brake system caused the vehicle to completely shut down. caused problems with the remote communicating with the starter and all system malfunctions activated.

Hot weather acceleration and blind spot monitoring system (bsm) issue: in extremely hot weather bsm off light turns on repeatedly while the vehicle is in motion or starting from complete stop. at the same time the infotainment system display flickers in sync with the bsm off light appearance. when this occurs there is a clicking sound coming from the front of the car/where the engine is located. the sound is accompanied by temporary loss of acceleration when in motion or starting to move from a complete stop. when this occurs while starting from a complete stop, the engine revolutions (rev) drops below 1k rpm despite gas pedal input thus the car would not move/accelerate for about 5 seconds. when it occurs when the car is in motion such as on the highway or merging onramp into the highway the car unsafely slows down despite gas pedal input. again this issue is observed during unusually hot days eg. july 22, 2017 in st. louis, missouri.

Turning to park her vehicle, in a parking lot, the vehicle suddenly accelerated and hit two parked cars in front.

The day was hot and i was in stop and go traffic with the ac set to 72 degrees in my 2015 mazda 3 with just 21k miles on it. my car unexpectedly stalled and the check engine and charging system/battery lights came on briefly in the dash. i had to shift into park and push the button to restart my vehicle. the car's ecu/pcm did not set any codes and the problem has not occurred again since that hot day. this is a danger because the sudden loss of power could result in a rear end collision luckily i was in stop and go traffic. dealer and mazda have been slow to investigate this thoroughly. feels like they just want to send me on my way without doing a thorough investigation of this issue.
