2018 Mazda CX-5 driver assist problems

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I am reporting a safety issue involving engine failure and fumes entering the vehicle cabin as well as unintended braking post major engine repair at 75,000 miles on my 2018 Mazda CX5. My vehicle developed engine problems consistent with a cylinder head/coolant defect and began allowing fumes/smoke to enter the cabin while driving. This created a health and safety concern for occupants. I reported this to the dealership and was told the vehicle was safe to drive despite the presence of fumes in the cabin. A major engine repair was later performed. A few days following the repair, additional warning lights and system malfunctions appeared, including brake system warnings, and the vehicle later braked unexpectedly while driving nearly causing me to be rear-ended. The vehicle has been inspected by the dealership, but the root cause of the fumes and subsequent safety issues has not been clearly explained. This situation created a safety risk due to exposure to fumes inside the cabin and unexpected vehicle behavior while driving. Smoke/fumes video and any additional documentation can be provided upon request. Attaching the costly invoice as well.

LANE DEPARTURE: BLIND SPOT DETECTION

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

While driving through town the braking system malfunctioned and the car came to a stop in the middle of the road with messages on dash saying the smart city braking support was malfunctioning as well as brake assist. Engine light came on as well as traction control light right after the car coming to a sudden hard braking stop. Drove straight to shop to check engine code which was p0882. I am so afraid of this happening on the highway with my daughter in the car. There is a recall for this system but my car isn’t under the recall so I'm sure there are others that are having the issue but aren’t covered under the recall either.

The infotainment center glitches and starts clicking things on its own, often changing the volume to all the way loud suddenly orchanging radio station constantly, startling me while I am driving and causing major distraction which can easily lead to an accident. Settings, including safety setting start to get changed on their own while driving as well. The edges of the screen on the infotainment center are also crackling on their own inside the screen somehow, and I am not sure if heat has caused this, and been making this issue worse because it is only ever wiped with a microfiber cloth.

FORWARD COLLISION AVOIDANCE: WARNINGS

The info-tainment system (Android Auto/Apple Car Play) is unstable and will come on at any time and change/delete settings and make calls, texts, etc. without any input. It is distracting as the screen shows what it it doing and the driver will need to make it stop. It could cause an accident. It has at times: Changed radio stations Deleted presets and other settings Deleted contacts from my phone Made phone calls and sent texts Deleted and reset the navigation to a destination not selected by the user. I understand this is called ghost touch and requires the touch screen to be fixed although I have never used the touch screen. I understand they recalled and fixed the 2016 to 2017 cars, but I have to pay to get the 2018 fixed out of pocket. This has been happening and getting worse for the past 6-8 months. Also, the forward collision has alarmed when there was nothing in front of me.

FORWARD COLLISION AVOIDANCE: WARNINGS

Mazda vehicles currently have an infotainment system that that is touch screen when the vehicle is stopped or below 10 MPH. Above 10 MPH, the touch screen disables and can only be used with the control console. Mazda infotainment systems have a "ghost touch" issue where when stopped, will behave abnormally and select random menus, options etc. Today while stopped at a red light, this ghost touch issued caused the infotainment system to TURN OFF blind spot monitoring and smart city brake support (automatic braking.) Due to the ghost touch, the control console wheel does not over ride the ghost touch issue. I could not turn these safety features back on until I started moving the car (accelerating ABOVE 10 mph) while driving at which point the touch screen "disables" and only allows the input of the manual control wheel. Mazda is aware this is an issues and refused to recall/fix these defective units outside of warranty without charging $500 - $1000 per customer.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

FORWARD COLLISION AVOIDANCE: WARNINGS

On 7/30/23, I was driving home from church, and was driving on the freeway in the fast lane when my 2018 Mazda Cx-5, that was only 5 years old, with only over 33.2K miles on it, started to stall. Thankfully, it didn't come to a complete stop, but slowed down tremendously, and had at least 5 malfunctioning lights come on all at once. The car wouldn't go over 25 miles afterwards. I was very thankful to make it home safely, but this was very alarming, since I never had any issues with that car, and always kept it very well maintained. For a car that was only 5 years old and had only 33.2K miles on it, to experience such a drastic problem, is very confusing. It was very concerning that the car almost came to a complete stop unexpectedly without any warning ahead of time, especially while driving in the fast lane on a freeway. I also took pictures of the malfunctioning lights that came on right after the incident took place. I had the car towed into the dealer the next day, and they told me that it was unusual that my engine would do that. They said that it needed a tune up earlier than expected. I was told that the 3rd cylinder was misfiring, and also when the engine isn't working properly, everything else in the car would shut down. Now, why would a car that's been very well maintained, with only 33.2k miles on it need a tune-up? And I always kept up with the oil changes on time. I found out that there was an engine recall on these particular models, but I was told by Mazda that my VIN # did not qualify; however, what I experienced, did fit the description of the recall. I've since then, decided to trade in the car, because I was just too afraid to continue driving it after this experience. I am however, very upset that I had to give up a car that I invested a lot of money in and took very good care of, and only had 33.2k Miles on it.

FORWARD COLLISION AVOIDANCE: WARNINGS

When I drive 100 to 150 fest the front camera blocked warning light come on. The only way to reset is to stop turn of car and restart, only to have it happen again and again. The main thing is when and if I can get into cruise control and I am on a major highway and have the cruise set unannounced the warning comes on and turns off the cruise control. If there is someone close they run up on me. I have had it back to the dealer and have called Mazda, all they said was maybe the sun was setting it off, I guess I can only drive at night. The dealer had the car for over 2 weeks and did not fix it. I have recently discovered that if I keep the cruise control on it will not do it, it is very frustrating and now it is off warranty.

The contact owns a 2018 Mazda CX-5. The contact stated that while driving at various speeds with the cruise control and the auto distance features activated, the vehicle would not accelerate while depressing the accelerator pedal. On several occasions while attempting to accelerate overtake a second vehicle, the speed suddenly decelerated instead. After turning off and restarting the vehicle, the vehicle operated as designed. During the failure, the Automatic Braking and Back Over Prevention camera was displayed. No further information was available. The vehicle was taken to the local dealer who performed a software update and later replaced the throttle body however, the failure recurred. The manufacturer was not yet notified of the failure.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

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!
