2015 Infiniti Q50

I WAS DRIVING MY INFINITI Q50 and puled up to a light. When it turned green I proceeded when I noticed my check engine light comes. It won't shift past 3rd gear. it seems to be in limp mode but there was a tractor trailer barreling down on me. So I get to 35 MPH and ride the side of the road. Once I got home I did a search and apparently there are A LOT of issues with this transmission. Most indicated it was the valvebody and that it could cost upward of $2,500.00 plus there is a back order on them. This is my only car and can't have it tied up to long. I have an appointment to have it diagnosed this coming Wednesday, 06/09/2021. I can't drive it or I will burn up the transmission. If there is such a large problem I would think this would have a recall on it. My car only has 65, 624 miles on the clock. This needs to be addressed. I am hoping for a miracle when it gets diagnosed but with all the evidence out there about the bad transmission in these cars I am expecting the worse.

On 5-25-2021 while merging into traffic on busy I-75. My 2015 Infiniti Q50 did not change into a higher gear as it should have causing the vehicle to not accelerate and lose power then the check engine light came on a few seconds after failure.This failure of the vehicles drive train placed my wife’s life and my life in extreme danger in which we were not able to accelerate with the flow of traffic and was nearly ran over by several semi tractor trucks. The vehicle is in the repair shop for the transmission valve body failure and replacement. I’ve looked this issue up online where numerous owners of this type vehicle have complained and described this as a common problem with these vehicles.

WHEN I BOUGHT MY 2014 INFINITI Q50 I PUT IT ON THE ROAD AND THEN I STARTED RECEIVING RECALLS. I ALSO HAD SEVERAL LIGHTS ON. I BROUGHT IT BACK TO DEALERSHIP THEY DID SOMETHING LIKE CLEARING THE LIGHTS WITHOUT EVEN LOOKING AT IT. 45 DAYS AFTER I BOUGHT THIS VEHICLE I WAS IN A SERIOUS MOTOR VEHICLE ACCIDENT. I ALMOST DIED AND I LOST MY SPLEEN. ONE OF THE AIRBAGS DIDN'T DEPLOY WHICH WAS THE REASONING FOR LOSING MY SPLEEN. I BELIEVE MY STEERING LOCKED UP AND ENDED UP HITTING GUARDRAIL. TOTAL LOSS. I LOST 4,000 BECAUSE OF THIS ACCIDENT NEVER MIND I ALL MOST LOST MY LIFE!!! THIS ACCIDENT HAPPENED ON THE HIGHWAY.

MY CAR PAUSE AND JERKS THEN STOPS. THIS IS THE SECOND TIME THIS HAS HAPPENED AFTER BEING FIXED. THE MECHANIC SAID THEY HAD A RECALL ON THE 2016 MODELS FOR THIS BUT NOT THE 2015 BUT HAD TO CORRECT MANY OF THE 2015 MODELS. THE CHECK ENGINE LIGHT CAME ON AFTER IT STOPPED. I WAS ON THE INTERSTATE THE LAST TIME WHEN IT STOPPED. I AM AFRAID THAT IT MIGHT HAPPEN AGAIN WITHOUT ANY WARNING. THIS IS A LIFE THREATENING DEFECT THAT INFINITI NEEDS TO CORRECT ASAP.

TL* THE CONTACT OWNS A 2015 INFINITI Q50. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 70 MPH, THE VEHICLE JERKED, SHIFTED GEARS, REDUCED SPEED, THE ODOMETER FLASHED, THE CHECK ENGINE WARNING LIGHT ILLUMINATED, AND THE HEATING AND AIR CONDITIONING SYSTEM WENT FROM COLD TO HOT. THE CONTACT GOT OFF THE NEAREST EXIT AND PULLED OVER AND WAITED A WHILE BEFORE CONTINUING TO DRIVE HOME TO PARK THE VEHICLE. THE CONTACT STATED THAT A DIAGNOSTIC CODE READER RETRIEVED DTC CODE: P0720 (OUTPUT SPEED SENSOR). THE CONTACT CONTACTED INFINITI OF TAMPA (4600 N DALE MABRY HWY, TAMPA, FL 33614; (813) 694-1579) AND WAS INFORMED THAT THE CAMSHAFT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 65,000.

WAS DRIVING MY INFINITI Q50 ON A NORMAL DRY DAY WHEN ALL OF A SUDDEN IT DOWN SHIFTED OR FELT LIKE I WAS DRIVING A STANDARD MODEL VS AUTOMATIC... I PULL OVER MY ENGINE LIGHT COMES ON.. I TURNED OFF ALL SENSORS ASSOCIATED WITH THE INTELLITOUCH SYSTEM THINKING IT WAS NOT JUDGING THE DISTANCE CORRECTLY BETWEEN CARS BECAUSE IT WILL AUTOMATICALLY SLOW YOUR CAR DOWN... CONTINUED DRIVING AND I'M NOTICING AS I TRY TO ACCELERATE MY CAR IS NOT SHIFTING INTO 3RD GEAR... SO I GET TO ABOUT 35-40 MPH AND NOW I CAN TELL IT'S REVVING IN THE SAME GEAR..GET HOME GOOGLE THE ISSUE AND IT SEEMS THE VALVE BODY ON THE 2015 Q50 HAS A THREAD... GO TO YOUTUBE THIS GUY HAS A VIDEO ABOUT HIM BEING TOLD IT'S THE SPEED SENSORS... BUT WHEN HE WENT FOR REPAIR INFINITI INFORMS HIM THE VALVE BODY NEEDS REPLACING. I TOOK MY CAR INTO AN INFINITI DEALER , SPENT $180 TO HAVE A DIAGNOSTIC RUN AND WAS TOLD THEIR IS A SERVICE BULLETIN FOR THE SPEED SENSORS THAT THEY SHOULD JUST REPLACE THE VALVE BODY. THE VALVE BODY IS $1635 AND ON A NATIONAL BACK ORDER AS OF AUGUST 2020 WHEN I'M EXPERIENCING THIS ISSUE.. CALLED INFINITI CONSUMER AFFAIRS AND I'M TOLD WELL UNLESS YOU PAY FOR THE PART WE CAN'T DO ANYTHING TO GET IT EXPEDITED... IT'S BEEN 45 DAYS... SO I HAVE TO TIE UP $1700 AND DON'T KNOW WHEN THIS PART MAY BE AVAILABLE.. CAN'T DRIVE CAR BECAUSE I'LL BURN MY TRANSMISSION UP... THE VALVE BODY IN 2015 Q50'S NEED TO BE RECALLED...I COULD HAVE BEEN ON THE FREEWAY OR DRIVING TO OR FROM LOUISIANA FROM HOUSTON.. LUCKILY I WAS WITHIN 15 MILES OF MY HOME.. CALLED THE OTHER 2 INFINITI DEALERS IN HOUSTON NONE OF THEM HAVE IT IN STOCK AND HAVE AT LEAST 1 Q50 WAITING FOR REPAIR.. CALLED THE DEALER IN AUSTIN ALSO NO STOCK WITH 2 VALVE BODIES ON RESERVE... I HAVE 106000 MILES ON MY Q50 AND IT'S NO LONGER UNDER WARRANTY.. THIS ISSUE HAS BEEN REPORTED AT FEWER MILES LIKE 30K-50K SO HAS NOTHING TO DO WITH THE AGE OF THE CAR.

PLACE THE CAR IN REVERSE TO BACK OUT OF A PARKING SPACE. WHEN I GOT TO MY STOPPING POINT I APPLIED MY BRAKES TO STOP TO SHIFT GEARS TO GO FORWARD. UPON PRESSING THE BRAKES THE VEHICLE WOULD NOT STOP AND CONTINUE TO ROLL BACKWARDS I PRESSED HARDER TO STOP THE VEHICLE IT DID NOT STOP IT ROLLED OVER A CURB AND BACKED INTO ANOTHER CAR BEFORE IT STOPPED. ONCE I TURNED OFF THE CAR AND RE-STARTED THE CAR AGAIN THE BRAKES WORKED PROPERLY. DAMAGE OCCURRED TO BOTH VEHICLES.
