2016 Mazda CX-5

The low pressure fuel pump on my Cx-5 failed on my drive back home, while in a remote area. I was able to limp the vehicle home with a check engine light that illuminated (at the time of the incident) and erratic vehicle performance (uneven power deliver). This occurred on level ground at highway speed - no incident precipitated the part failure. Once home the following day, the vehicle would not restart. Upon diagnostic review, the vehicle had thrown two codes, one being a low fuel rail pressure (P0192 and P0171). This is a know issue for these defective (Denso) fuel pumps. The manufacturer should extend the recall to include vehicles manufactured prior to 2018.

My 2016 Mazda CX5 lost the main computer. This powers the nav system, radio, apps associated with the vehicle but most importantly, the rear view camera. As a result, the back up camera does not work properly due to the computer system remaining in a reboot mode. When I initially reported the problem to Mazda they indicated that they would order the part. They claimed supply chain issues and as a result, kept pushing the replacement delivery date forward. It has been over a year and was just advised there is another 4-5 months wait time. My wife and I have been very patient but recently, events took a turn for the worse. The car must have been designed with the rear view camera as a solution in the reduced visibility of the actual car design. My wife came close to backing into a child. This has scared us now and unfortunately the car can’t be traded in without taking a financial hit. There has been no real answer why this part is taking 1.5 years for delivery but we can’t believe the lack pf attention that Mazda has placed on our concerns. This is absolutely a safety issue and someone needs to investigate if this is happening with many of these vehicles. I would hate to see someone lose their life due to corporate neglectfor safety. Thank you for listening.

I was driving on the freeway, going 60-65mph for about 10 minutes. All of a sudden, the engine went from ~2k RPM to ~4 RPM. The speed stayed the same. And then it happened again a few minutes later. A few days after this incident, while driving on the freeway, going 60mph, the car refused to go past 60mph. This also happened ~2 weeks prior. This would have caused an accident had I needed to speed up to avoid an issue but my car refused to go any faster on a flat road.

The check engine light came on when I was in my way home. This morning when I started my car, the engine reved on its own and then it went to 0. This is super dangerous. The car could have stopped in the middle of the freeway. I had my car towed to a local mechanic. The error code that came up was p0192. Looks like there is a recall for the fuel pump issue for many mazda, yet mine isn’t part of it.

Repair to be covered under Mazda Power Train Warranty. Additional concern: Short and Long Term residual effects on other engine components. Other reports: none. Awareness: I’ve come to understand that there seems to be similar issues with certain model years/production runs that might not be reported due to being covered under warranty. The consumer provided the correct VIN for the vehicle.

smart key. during driving all the lights on the dashboard come on and the siren goes off and unable to have it turn off. After a period of time, its wears down the battery and it is no longer drivable. First time, it was towed to the AAA auto repair and they could not find anything wrong with it. The 2nd and 3rd time, AAA towed it back to Maita Mazda where we purchased it in good faith less than two months ago, and their service department could not find anything wrong with the electrical system. They replaced the battery the seond time, and the issue still occurred again when I turned it off. Then turned it back on as I needed to close the driver side window, and it would not turn on. No one seems to believe me, and we cannot get Maita to take it back and give us another vehicle in its place. It is extemely dangerous to drive in traffic, and we only bought it because it has a big enough trunk for my spouse's walker, and later a wheel chair. It is paid for in full,

Last month, my vehicle suddenly applied the electronic parking brake (EPB) while I was driving. The EPB & related warning lights illuminated & would not release until the vehicle was turned off. After turning off the vehicle, the EPB motor could be heard applying the brake to the rear wheels. When the car was restarted, the EPB would remain off for a period of time but would then suddenly reapply. I took my vehicle to a Mazda dealer & they determined the calipers & EPB motor had failed due to my vehicle not being placed in service mode by the brake servicer. This explanation makes no sense because the brakes were replaced over a year ago (& not since) with thousands of miles being driven since then without this issue arising. I also conducted my own research & found that Mazda has issued at least 3 separate technical service bulletins (TSB) on this issue. The first two recommended replacement of the EPB switch & the third determined that defective calipers were the cause and should be replaced. I asked the dealer to save my calipers & confirmed that they are part of the defective batch noted in this TSB. I have contacted Mazda (including their legal counsel) & they are unwilling to provide any explanation or engage in any sort of investigation. As former legal counsel for an automotive company, I believe this presents a serious safety issue for consumers based upon the fact that a parking brake could randomly engage while driving & cause sudden loss of speed/control. Thankfully, this did not result in harm to my family, myself or others. I am certain that this issue is affecting others based on chatboard discussions I have found online related to this topic (which helped me find the TSB). I am concerned that Mazda may have attempted to undertake a silent recall via this TSB where in warranty customers are covered & out of warranty customers are given the 'service mode' explanation to justify their responsibility. This should have been handled as a recall by Mazda.

While driving to the airport suddenly all dashboard lights came on and engine "died" during the drive about 50mph. My wife who was driving, was lucky not to get into a crash and steered the car to the side to a full stop . The tow truck driver tried to restart the engine w/o success. The garage determined it is a catastrophic engine failure and need to be replaced. About 2 weeks prior we had an engine warning light. The car was taken to our regular serviced garage and was inspected w/o any issues and light was reset. All routing maintenance has been performed by same garage. There are similar reports on the web about total engine failure of Mazda CX5 during driving!!!
