2015 Mazda CX-5 Engine Problems

While driving on the freeway the check engine light came on. I was able to drive the car home the remaining 20 minutes but there was some noticeable difficulty accelerating. When I went to turn on the car later that day the engine would not turn over and there was an audible rattling/chugging sound and the car itself shook. I was unable to get the car to start and the check engine light remained on. I had AAA check the battery the next day and confirm it was not a battery issue and a diagnostic revealed the P0192 code. AAA towed it to their shop where it was confirmed by the manager mechanic that the issue was with the high pressure fuel pump and that it was causing an issue with the low pressure fuel sensor as well. The mechanic was unable to determine what caused the pump to fail and has quoted me nearly $2000 to fix it. After some searching online it has become clear that this is an issue many other Mazda owners have faced and that is even a recall for the pump for years and makes from Mazda due to a known issue with DENSO fuel pumps causing this exact issue. Despite this being known and DENSO having admitted issue with fuel pumps in cars dating back to 2013, Mazda has not recalled the vast majority of the cars that could be affected. From information I've gathered, it is entirely possible that my vehicle could have just stopped running in the middle of the freeway due to this issue which obviously would have put me in great danger of an accident. To summarize: Low pressure fuel sensor and high pressure fuel pump with error code P0192 are cited as the issues. It's possible this issue can cause the car to stop running with no warning, which would be extremely dangerous especially on the freeway. The problem has been reproduced and confirmed by a AAA mechanic shop. The vehicle has been inspected by the AAA mechanic but no others. The check engine light came on but was not clear how extreme the circumstance was.

2015 MAZDA CX5 2.0 L, WELL MAINTAINED; RECOMMENDED OIL USED AT PROPER INTERVALS, WITH 130,000 MILES, MOSTLY HIGHWAY DRIVEN. WITH NO WARNING LIGHTS AND/OR SOUNDS, VEHICLE STARTED LOOSING POWER AT AROUND 30 MPH IN THE CITY AND ENGINE COMPLETELY STALLED. AAA WAS CALLED TO START THE VEHICLE TO NO AVAIL, BATTERY CHECKED OUT OK. TOWED TO MAZDA DEALERSHIP IN WICHITA, KS. DEALER SERVICE EXAMINED VEHICLE AND FOUND A VALVE STEM BROKEN AND LYING ON TOP OF ENGINE, VISIBLE THROUGH THE SPARK PLUG WELL. AS THE OWNER, ALONG WITH THE SERVICE MANAGER, I SAW THE BROKEN VALVE STEM IN THE ENGINE BUT ALSO NOTICE MY ENGINE WAS EXTREMELY CLEAN ON THE INSIDE WITH CLEAN OIL AS WELL, NO EVIDENCE OF DIRT AND/OR SLUDGE OF ANY KIND. VEHICLE OWNER COMMENTED TO THE DEALER HOW CLEAN THE ENGINE AND THE VEHICLE WAS KEPT INSIDE AND OUT. DEALER RESPONDED BY TEXT TO OWNER, NEW ENGINE REPLACEMENT, AT THE COST OF $7000; USED ENGINE WITH 91,000 MILES AT $5000. DEALER STATED AFTER 60,000, VEHICLE OF OUT OF WARRANTY. OWNER RESEARCHED AND FOUND EVIDENCE THE FAILURE IS LIKELY DUE TOO ENGINE DESIGN. MAZDA BUILT AN ALUMINUM ENGINE WITH HIGH COMPRESSION RATIO, BUT BUILT IT LIGHTER AND WITH SMALLER COMPONENT PARTS. ACCORDING TO ENGINEERS, THAT'S A RECIPE FOR VARIOUS COMPONENT PARTS AND ULTIMATELY OVERALL ENGINE FAILURE. THE SKYACTIV ENGINE OPERATES AT 13.0 COMPRESSION RATIO, BY DESIGN; IF NOT DESIGNED PROPERLY AND BEING IT'S NEW TECHNOLOGY, FAILURES LIKE INTERNAL COMPONENT PARTS AND THE ENGINE, ARE LIKELY. OWNER'S VEHICLE AT DEALER FOR ALMOST 3 WEEKS AND THEY ARE OFFERING NO ASSISTANCE TO REPAIR THE VEHICLE. THERE NEEDS TO BE AN INQUIRY INTO THE DESIGN OF THE SKYACTIV ENGINE AND ADDRESS MAZDA ALLEGING OWNER'S ARE ABUSING VEHICLES AND CHARGING EXORBITANT PRICES FOR MECHANICAL ISSUES CAUSED BY THEIR PRODUCT DESIGN. OWNER CURRENTLY HAS TWO 2015 MAZDA CX5'S . DEALER/MAZDA OFFERING NO ASSISTANCE.

MY VEHICLE HEATER CORE HAS PLUGED UP AFTER 48,000 MILES. I CANT DRIVE IN COOL WEATHER DO TO FOG WINDSHIELDS. THIS IS A HUG PROBLEM WITH MAZDAS CX-5 BETWEEN 2014 AND 2016.

TL* THE CONTACT OWNS A 2015 MAZDA CX-5. WHILE DRIVING 30 MPH, THE VEHICLE STALLED WITHOUT WARNING AND LOST POWER COMPLETELY. THE CONTACT WAS ABLE TO COAST THE VEHICLE INTO A PARKING LOT. THE CONTACT RESTARTED THE VEHICLE AND SEVERAL BSM OFF, TIRE PRESSURE MONITORING SYSTEM WARNING LIGHT, TCS/DSC INDICATORS REMAINED ILLUMINATED. LANNAN MAZDA IN LOWELL, MASSACHUSETTS WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 44,740. *TT *TR

MAZDA ENGINE DEFECT I PURCHASED A 2015 MAZDA CX-5 USED TWO YEARS AGO. WHILE MY DAUGHTER WAS DRIVING TO WORK SHE NOTICED A LOUD TICKING NOISES FROM ENGINE. SHE SCHEDULED A SERVICE WITH MAZDA DEALERSHIP AND THEY STATED THAT THE PROBLEM IS WITHIN THE INTERNAL COMBUSTION AND THE ENGINE NEEDS TO BE TORN DOWN FOR COMPLETE DIAGNOSIS, HE FURTHER SUGGESTED THAT I REPLACE THE DEFECTIVE ENGINE WITH A MAZDA NEW ENGINE TOTALING OVER $7000. ALARMED, I RESEARCHED AND FOUND OTHER MAZDA OWNER EXPERIENCING THE SAME PROBLEMS. THIS CONSTITUTES MY FORMAL COMPLAINT FOR MAZDA DEFECTIVE ENGINES.

TRANSMISSION ISSUE: I TURNED ON THE CAR IN A PARKING LOT AND TMPS AND SCSB CODE AND THE TIRE PRESSURE LIGHTS CAME ON. I HAD ABOUT 15K ON THE CAR AND IT WAS JUST A YEAR OLD AND DUE FOR IT'S SERVICE. I WROTE DOWN THE CODES AND FIGURED I WOULD TELL THE DEALERSHIP WHEN I TOOK IT IN FOR SERVICE. I DROVE A LITTLE WAYS AND STOPPED AT A LIGHT. THE CAR STARTED TO MAKE A LOUD NOISE AND SHUDDER. I DROVE THROUGH THE LIGHT AND PULLED UP TO THE STOP SIGN. THE TACHOMETER REVVED UP BUT THE CAR WOULDN'T GO ANYWHERE. I MADE IT TO THE STOP SIGN, PUT ON MY FLASHERS AND PUT THE CAR IN PARK. I TURNED IT OFF AND TURNED IT BACK ON AGAIN. I WAS ABLE TO DRIVE A FEW MORE FEET THEN AGAIN THE ENTIRE ENGINE REVVED UP AGAIN. REPEAT THIS ABOUT 6 MORE TIMES. I WAS ABLE TO MAKE IT THE MILE TO MY HOUSE DOING THE DRIVE, STOP, TURN OFF, START AGAIN AND REPEAT. I HAD IT TOWED TO THE DEALERSHIP. THE DEALERSHIP FIXED THE CAR AND SAID IT WAS THE TRANSMISSION AND THAT MAZDA WAS ABLE TO TELL THEM HOW TO FIX IT BECAUSE THEY'D SEEN IT BEFORE AND IT WAS A A "SHIFT CONCERN AND SOFTWARE UPGRADE NEEDED." I'D REALLY LIKE TO SAVE SOMEONE ELSE FROM GOING THROUGH THIS SO I WANT TO REPORT IT. IF I'D BEEN DRIVING FASTER AND THE ENGINE SHUT DOWN LIKE THAT, I COULD HAVE HAD A SERIOUS ACCIDENT. HAS ANYONE ELSE HAD THIS PROBLEM? ALSO WHY WASN'T THIS REPORTED ON ANY OF THE CAR/DRIVER, CONSUMER REPORTS REVIEWS. THIS IS A SERIOUS ISSUE AND PEOPLE SHOULD CONSIDER IT BEFORE THEY BUY THE CAR. MAZDA SHOULD FIX THE ISSUE IN THE CX-5 SO THAT IT DOESN'T HAPPEN.

I PULLED OUT OF A PARKING LOT AFTER HAVING THE VEHICLE PARKED THERE FOR ABOUT 2 HOURS- THE VEHICLE IS BRAND NEW WITH 725 MILES ON IT AND HAS BEEN DRIVEN ON CITY STREETS ONLY SINCE I'VE HAD IT. I PULLED OUT OF THE PARKING LOT, DROVE 1 BLOCK IN NO TRAFFIC, AND WHEN PARKED AT THE STOPLIGHT, NOTICED A BIT OF SMOKE/STEAM COMING FROM UNDER THE HOOD. NOT A LOT AND THE CAR WASN'T OVERHEATING. SINCE THE CAR WAS SO NEW, I DIDN'T KNOW WHAT TO THINK OF IT BUT THOUGHT MAYBE IT WAS A FLUKE. DROVE IT FOR 2 MORE ERRAND STOPS ON 30MPH STREETS AND THEN HOME. THE NEXT DAY I PULLED OUT OF MY DRIVEWAY AND NOTICED THE A/C ISN'T COOLING. I TOOK IT TO THE MAZDA DEALERSHIP THAT WEEK ASSUMING WHATEVER IS WRONG WOULD BE UNDER WARRANTY. THEY SHOWED ME A SMALL PINHOLE IN MY A/C COMPRESSOR AND INFORMED ME THAT A ROCK MUST'VE FLOWN THROUGH MY GRILL AREA AND LEFT A HOLE IN THE COMPRESSOR, CAUSING THE FREON TO LEAK. IT WOULD COST AROUND $1500 TO FIX AND ISN'T COVERED BECAUSE CONSIDERED "ROAD DEBRIS." THE BIGGEST ISSUE I HAVE IS THAT THE DESIGN OF THE GRILL IS SO OPEN, I CAN FIT MY ARM IN THERE. WHAT'S TO PREVENT THIS FROM HAPPENING AGAIN? EVERY TIME IT HAPPENS, THE PASSENGERS BREATHE IN FREON AND IT'S RELEASED INTO THE ENVIRONMENT. CLEARLY THE GRILL IS DESIGNED FAR TOO OPEN TO PREVENT FROM LARGE DEBRIS, LET ALONE A PEBBLE, DAMAGING THE A/C CONDENSER. SOMETHING NEEDS TO BE DONE TO RETROFIT THE OPENING AND PREVENT THIS FROM HAPPENING TIME AND TIME AGAIN. I DID RESEARCH AND DISCOVERED IT'S NOT UNCOMMON FOR THIS VEHICLE AND ONE PERSON REPORTED IT HAPPENING ON THE 2ND DAY OF HER OWNERSHIP AND THEN AGAIN A YEAR LATER. *TR
