general problems of the 2016 Mazda CX9

Vehicle “surges” at idle. 300-500 rpms at a time. Sometimes the brakes hold and sometimes not. Have nearly been in 3 collisions the last 2 days because of this issue. The ecm codes indicate throttle body or tps issue, both of which have been unfounded. Vehicle has 63,000 miles. Researching this topic online found that many others have had this issue with no associated safety recalls noted. I am hoping to bring light to this so someone doesn’t have to be injured or killed to have this rectified.

Traveling on the highway going on a road trip. Had vehicle inspected prior and no fuel system problems were noted. I was going 75mph with my family when there was a coasting feeling in the car. I looked and my check engine light popped on and my car immediately would not accelerate and we quickly lost speed. By the grace of god were we able to pull over safely! code p0132 was the engine code and after an hour, the engine light went back off and we were able to keep a safe speed traveling home. After speaking with a mechanic and dealership, I learned that this was a common problem with the denso fuel system. My vehicle was not included in a recent recall that included a different year of my vehicle. If manufacturers are aware that a major defect is out there, how many people have to have an accident or potentially cause a huge accident because a car made 2 years prior with the same part from the same manufacturer has the same dangerous problem? it’s ridiculous and I hope you look at this near fatal issue that has effected thousands of people, whose vehicles’ were made in 2017, 2016, 2015 and are not included in the recall.

My Mazda cx-9 ran out of gas on a major highway (route 90 in boston) and the gas gauge read half full. No 'out of gas' light went on and range (under information) said 191 miles remaining. My Mazda dealer told me the software needed to be reset (not done yet as of this writing). It is a major issue if the gas gauge is not reading properly and this is a software issue (a bug?). Mazda needs to fix this for all Mazda's and issue a recall so it does not happen again.

While driving the car in the 287 interstate highway in new jersey, I got the check engine light out of the blue and the car started decelerating in the high speed lane. Luckily I was able to manage and get the car to the road side shoulder. I was not able to start the car after this incident. We had to tow the car to the Mazda service center in greenbrook, new jersey. After running the car diagnostics (error code - p0192), they informed me that they had to update the pcm (power control module) software. Thats the only explanation which they gave which made no real sense. They did not provide any information why this issue occurred and what was done to make sure this issue does not occur in the future.
