2016 MAZDA CX-5 Vehicle Speed Control Problems

11/19/2023 - About 8 pm. on November 17, 2023, I was parking at my condo parking lot and slowly drove the car into the parking space when all of a sudden the car accelerated on its own. I immediately pressed on the brake pedal and it stopped. I felt fortunate that nobody was on the sidewalk. The same thing happened about a month ago but I thought it was just something unusual but now that it happened again I am very concerned and I am going to call the Maxda dealership to see what they say.

I own a 2016 Mazda CX-5 Touring with AWD. I purchased it brand new from a dealer--no miles on it. It's been a great car until this Sudden Unintended Acceleration problem (about 60K miles now). It's happened 5 or 6 times--twice when in a drive thru. It seems that if I am idling (not pressing on gas or brake) the car will sometimes suddenly accelerate. I have used suggestions to brake, then place car in neutral. That seemed to resolve the problem. However, recently I pulled up to my (rural) mailbox and the car tried to accelerate out of control. I had the brake on (was on a downhill) when it happened, so this was scary. I really had to press down more on the brake pedal, then shifted to neutral, then to park. The acceleration finally stopped. I did not observe tachometer readings during this or other events, but...

I WAS STOPPED BUT DID NOT HAVE THE CAR IN PARK WHEN VEHICLE LUNGED FORWARD AT HIGH SPEED. I WAS IN A DRIVEWAY AND HIT SOMEONE'S GARAGE.

I SLOWED DOWN IN MY NEIGHBORHOOD, GOING ABOUT 10 MILES AND HOUR, AND WAS COASTING INTO A PARKING SPACE AT ABOUT 5 MPH IN MY HOME NEIGHBORHOOD. IT WAS ABOUT 1:15 PM ON A SUNNY, CLEAR DAY. I WAS APPLYING THE BRAKE TO STOP THE CAR AS I PULLED INTO THE SPOT YET I WAS GOING SLOW AND COASTING STRAIGHT INTO THE SPOT. SUDDENLY, THE CAR SPED UP, THE BRAKES HAD NO RESPONSE, AND THE CAR JUMPED OVER THE CURB AND RAN INTO TWO BUSHES. I DID NOT HAVE MY FOOT ON THE ACCELERATOR, I HAD MY FOOT ON THE BRAKE...BUT MORE THAN ANYTHING, I HAD NO CONTROL, IT WAS UNINTENDED ACCELERATION. THEN THE CAR STOPPED AFTER I HIT THE BUSHES. I WAS SHAKEN, BUT NO BAGS DEPLOYED. I THEN MOVED THE CAR OFF OF THE GRASS, AND PULLED THE CAR AROUND TO THE SAME PARKING SPACE. THIS TIME THE...

SUDDEN ACCELERATION TURNING LEFT PULLING INTO A PARKING SPOT. FOOT ON BRAKE/OFF OF ACCELERATOR, CRUISE CONTROL OFF, SLOWLY PULLING IN. ACCELERATED ENOUGH TO JUMP CURB ONTO SIDEWALK. ABLE TO BREAK JUST ABOUT THREE FEET SHORT OF BRICK BUILDING. CAR AT DEALERSHIP FOR SEVERAL DAYS. TECHNICIANS UNABLE TO RECREATE OR DISCOVER PROBLEM.

COASTING. DRIVING TO A STOP SIGN OR STOP LIGHT OR STOPPING POINT AT A DECLINING SPEED FROM 30MPH TO 25/20/15MPH INTERVALS ARE WHERE THE 'TUGGING'/'STUTTER' HAPPENS. DEALERSHIP SAYS IT IS NORMAL OPERATION FOR THE CAR TO SHIFT INTO GEAR WHEN DECLINING IN SPEEDS. EVEN CORPORATE AGREED WITH THEM. THE ONLY THING THAT IS NOT NORMAL IS HOW COME AWD VARIATION DOESN'T HAVE THIS ISSUE? MY OLDER MAZDA 3 FROM 2009 I DROVE DIDN'T HAVE THIS ISSUE. TESTED A MAZDA 3 NEW 2018 AND THEY HAD THIS ISSUE. ALSO TESTED A SALES DEPARTMENT 2016 FWD CX 5, SIMILAR ISSUE. MY FRIEND WHO IS A PHYSOCLOGIST, HER CX 5 2016 HAS THE SAME TUGGING ISSUE. DEALERSHIP SAID IT COULD BE A TORQUE CONVERTER/TRANSMISSION/ OR COLD WEATHER WITHIN TH TRANSMISSION LINES. NO ERROR CODES WERE PRESENT WHEN THEY CHECKED. THE DRIVING EXPERIENCE SEEMS VERY DEGRADING FOR THE NEWER MODELS. THE ABRUPT TUGGING COULD...

2 INCIDENTS OF SUDDEN ACCELERATION WHILE MAKING A RIGHT HAND TURN INTO PARKING SPACES FIRST ON 5/18/17 AND SECOND ON 12/15/17. THE AIR BAGS DEPLOYED THE FIRST TIME BUT NOT THE SECOND TIME. THE INSURANCE COMPANY IS ORDERING AN ENGINEER INVESTIGATE SINCE IT OCCURRED ON 2 SEPARATE OCCASIONS

MY COMPLAINT IS IDENTICAL TO COMPLAINT # 10913740. I SPECIAL ORDERED MY CX-5 & PICKED IT UP FEB 2017.DOES NOT SHIFT PROPERLY, REVS UP TO 6000 BEFORE ENGAGING, CAN'T ACCELERATE WHEN I NEED TO (LIKE MERGING ON FREEWAY OR CHANGING LANES). PLEASE SEE COMPLAINT # 10913740 BECAUSE HE DESCRIBES IT BETTER THAN I, A NON "CAR PERSON" CAN. I'VE PUT MY MY GAS FOOT TO THE FLOOR TRYING TO GAIN SOME SPEED SO I WOULDN'T GET REAR ENDED AND IT TAKES, LITERALLY, ABOUT 10 SECONDS TO RESPOND AT ALL. THE DEALER CLAIMS IT IS SHIFTING AS DESIGNED & SAYS THEY CAN'T RECREATE THE PROBLEM. CAR WAS THERE @3600 MILES & THEY TOLD ME THE TECH COULDN'T FIND ANYTHING WRONG WITH THE CAR BUT DID I WANT A DRIVE WITH HIM. I DID ONE, & HE TRIED TO TELL ME THAT REVVING TO 5000 WHEN ON A SMALL INCLINE WAS NORMAL....
