Two weeks after I got the vehicle, I was driving on a highway doing speeds of 45 to 74. The drivers land change assist was not working as a car was right beside me several times I noticed and the light was off. My son mentioned it. Dec 22, 2017 2) I was driving at dusk on cruise control 74 mph and the car suddenly braked and a warning brake! was on the dash. I was in the fast lane with no objects or car in front.
The contact owns a 2017 Mazda Cx-5. The contact stated that the Smart city brake system failed to function properly when activated and modified to a specific distance or speed. The dealer (Mazda of mesquite, 15900 lyndon b johnson fwy, mesquite, TX 75150, (972) 686-6200) was notified, but was unable to replicate and diagnose the failure. The manufacturer provided a TSB that indicated that, without a warning indicator or warning chime, the function was not able to be replicated and the system was performing normally. The manufacturer did not send a technician to test drive the vehicle and determine if the function was properly working. The failure mileage was 0.
Known ghosting issue caused by manufacturing and diagnosed by Mazda. The lights inside flicker, the radio/navigation/telephone (bluetooth) starts, stops, and moves as it wants to. This causes distractions and is unsafe while driving. There are recalls on other model cars for this, however, Mazda won't fix my car even though they acknowledge this was a manufacturing problem.
The car battery does not get fully charged even after long trips and continuous use of the vehicle. It has been so ever since the vehicle was purchased brand new and maintained meticulously with all service performed on-time at the dealership. Even after long trips exceeding 350 miles, the battery would charge only up to 50% (12. 2 volts) and never to 100% (12. 7 volts). Thereafter it would quickly discharge to low (<11. 9 volts) if a few shorter trips were made. Upon bringing this to the dealer’s attention while the car was still under warranty, they ran a battery and alternator test and quickly dismissed the issue saying that both the battery and alternator were working fine. Nevertheless, in just two years the oem battery failed from constantly being in a state of low charge, despite using the vehicle regularly for long trips. Because the dealer refused to honor the warranty, I had to replace with a new battery at my own cost. Now the new battery doesn’t charge beyond 50% (12. 2v) either, and I have to routinely charge it every few days to full (12. 7v) with an external battery charger just so the battery doesn’t die and either gets me stranded on the road (safety issue for myself and others) or damages computers/other electrical components (reliability and repair issue).
