Automatic Emergency Braking Problems of Mazda CX-5 - part 2

There was a warning "chime" and then this message appeared on the instrument panel. "front radar malfunction". The car was in the left lane on the PA turnpike going approximately 73 miles per hour. The car immediately began a rapid deceleration after the warning "chime". Automatic braking activated. The driver could not accelerate. Traffic was heavy with a trailer truck to the right and cars behind. There were no vehicles in front of the decelerating car. The vehicles behind were able to slow and avoided collision. We were forced to pull over in a very narrow center medium next to a large concrete divider. It was a very dangerous place to stop. The engine was turned off for approximately a minute. When it was started there were no messages and the driver had full control of the car. The car is available for inspection. The dealer will be contacted tomorrow. The car has been in service for 23 months and has been driven 12,200 miles. The road surface was wet from recent rain and the car had been driven through a downpour with water pooling on the road approximately 15 minutes before this incident.

When the system think there might be a collision and initiates a hard braking even when there might be enough space in front of you. Multiple times, the car behind me had to do a hard break as well not to hit me from behind. This also happens when switching lanes. As you are in the middle of switching, if sometimes thinks you are getting to close to the car in the original lane and it starts a hard break. Since I’m in between lanes, it causes the car on the other lane to do a hard break also, almost causing a chain accident. A google search revealed multiple people complaining of that. The system is too aggressive even at it’s lowest setting. Mazda informed me I can only turn it off one drive cycle at a time. This system has almost caused more accidents than it protected me from them.

Situation: driving uphill on hwy 120 on new priest road, big oak flat, CA, two lane mountain road. Slow car in front of me and a delivery truck tailgating. Slow car eventually moves aside in a turnout and I accelerate to open up space between myself and what I thought would be the truck but somehow the slow car returned to the driving lane ahead of the truck. I continue to accelerate to attempt to open up space between myself and the car behind me when I lost power, the car behind me moves to the opposing traffic lane to avoid rear ending my car that is running in degraded mode (accelerator has no effect, basically moving on idle power) and narrowly misses an oncoming car as I move towards the right edge of the right lane. Truck behind me has to brake hard to avoid rear ending me. There was no shoulder to pull over to at that location immediate location. I pull over a few hundred yards further at a safe location. Grade was perhaps 4% to 6%. Weather: hot 90 degrees speed: accelerating from 35 to 50 mph (guess) diagnostic lights: Smart city braking system failure warning, plus a lot of other warning lights lit including check engine light. Aftermath: I pulled safely over, stopped the engine, waited a while and restarted the engine and the car returned to it's normal driving behavior and completed my trip. Other information: this is the 3rd occurrence of this behavior. Each time I have had Mazda look at the problem. 1st occurrence they replaced the cylinder coil, 2nd occurrence they replaced a spark plug for misfire. 3rd occurrence, to be determined.

Ebrake engages on its own when starting up the vehicle. You are unable to turn the ebrake off without restarting the car. The repair shop stated it is a problem with the computer module. A quick search of the internet shows that this is a common issue with this year's make and model. Luckily, the ebrake has not engaged itself yet while driving the vehicle.

I buy this car 2 years ago and 3 months later is starting having problem with rear passenger brakes I took the car to the mechanic and he change disc and brakes pads. A couple months later is starting having the same problem in the same area but this time is was smell burn coming through the wheel I'm stop the car to check was is going on when I check the brakes it was very very hot. I take the car to the mechanic and he told me the epb is bad he changed everything disc, brakes pads,caliper and epb motor. He said try to don't used the epb too much or I'm going to see you again with same problem ??. . . So I'm stop to use the epb for long time.

This is make me crazy the epb need to be fix from the dealer please make this common problem a recalls to getting fix for those people got the same issue.

Heading south doing 70 mph on 95 in the far left lane on a rainy day . . . . Came over a hill and started to hydraplayne. . . . . Seems like the automatic pilot took the car over ,,,,,I lost the fight with the steering wheel and did two 360s all away across 4 lanes of traffic to the grass inbankment on the other side,,,,,lucky to be alive . . . . . . Very lucky.
