2017 MAZDA CX-5. CONSUMER WRITES SEEKING REIMBURSEMENT FOR REPAIRS MADE TO VEHICLE. THE CONSUMER STATED THE NAVIGATIONAL SYSTEM KEEPS REBOOTING ITSELF. THE VEHICLE WAS REPAIRED AND THE CONSUMER WANTS TO BE REIMBURSED FOR ALL REPAIRS.
The Mazda SCBS (Smart City Brake Support) system malfunctioned in my vehicle. This system can inadvertently apply the brake if the system malfunction. It was told to me by the dealership that it was a known issue with the CX5s around this model year and I really think it should be a recall. Not having this safety-critical system working properly because of a manufacturer defect isn't a great thing to put on the traveling public. Not having this system could cause people to become complacent expecting the system to work properly and stop them from rear-ending another vehicle. The warning light randomly came on one day, and would also come on from time to time which the manufacturer states as "normal". I had the system inspected by Mazda and they told me "This is a common issue that we have seen frequently." I had to pay out of pocket $800 to get this safety-critical system repaired that really should be covered by the manufacturer due to a malfunction in their system.
The Adaptive Cruise Control system (collectively including the Lane Departure Warning, Forward Collision Warning, Smart city brake support etc.) on this SUV stops working abruptly and randomly while the car is in operation on the road. This is a major safety concern as it can crash into a leading vehicle in absence of adaptive cruise capabilities. The system generally resets or starts working again after a 5-10 minutes, but there is no rhyme or reason why it stopped working or when it would start again. It has happened in cloudy, harsh cold weather, and also on a bright, warm sunny day. This makes the ACC unreliable. The dealer could not reproduce the malfunction, as generally the car is stationary in the workshop or isn’t driven for a long enough time while testing.
Navigation/backup camera screen reboots constantly. This problem often occurs when I'm backing up. Mazda is aware of the issue as I have found many complaints on forums. It is not exclusive to the CX5. It appears to be all Mazda's, cars and SUV's.
