Cruise Control problems of the 2017 Mazda CX-5

Tl the contact owns a 2017 Mazda Cx-5. While driving 75 mph, the vehicle recognition system was on while the preceding vehicle was driving at a slower speed. The contact attempted to switch lanes, but the vehicle would not decelerate on its own. The contact had to depress the brake pedal to prevent a crash. The contact turned the cruise control off and back on, and the vehicle was able to drive normally. The dealer (jim click Mazda eastside, 1301 s wilmot rd, tucson, az 85711) was contacted. The manufacturer was not contacted. The vehicle was not diagnosed or repaired. The approximate failure mileage was 17,000.

According to consumer reports (Aug. 2017, page 58, last paragraph) the Mazda's new Cx-5's forward collision warning with low-speed automatic emergency braking standard should be applauded. These features malfunctions in las vegas during hot weather. Mazda knows about the problem and has no fix. We bought a Mazda Cx-5 on June 9, 2017. While driving on the freeway on July 21, 2017 the car quit working properly and we had three warning messages come up on the dashboard: 1. Smart city brake support malfunction 2. Smart brake system malfunction 3. Forward camera malfunction. Had I not been paying close attention while using the cruise control the car might have rear-ended the car in front at 60 mph. The dealer service staff I talked to on the phone when I got home said that Mazda knew about the failures. Mazda said these errors are caused by excessive heat and Mazda has had many complaints in many locations. There is presently no fix. It seems to work ok when the weather is cooler. These are safety features we purchased and they failed while we were driving in las vegas. The temperature was 104 at the time. Not excessive for las vegas nor other parts of the southwest desert. I currently have pictures of two of the warning messages that flashed on the dashboard and can be seen at https://photos. App. Goo. Gl/0mfdpf5wzvoux2sp2. This seems like a major flaw of the Mazda Cx-5 if their premier package safety features fails to work when the outside temperature is around 104. The car should not be recommended, or even sold, with these features until Mazda gets this fixed. Maybe other Mazda models have this flaw.
