2014 INFINITI Q50 Vehicle Speed Control Problems

MY CAR WAS DRIVING ALONG AND ALL OF A SUDDEN THE STEERING WHEEL GOT EXTREMLY TIGHT AND THE CAR WAS HARD TO STEER, I HAD TO PULL OVER TURN THE CAR OFF AND THE LIGHT WAS STILL ON, I WAS LIKE 2 MILES AWAY FROM MY HOUSE, TALKING TO A NEIGHBOR THAT HAS SAME CAR DIFFERENT YEAR, STATED TO CHECK RECALL HIS CALL DID THE SAMETHING YEARS AGO WHEN WE HAD A COLD (LOW TEMPERATURE) WINTER AND IT WAS REPLACED BY INFINITI DEALER. I NEVER HAD ANY ISSUE WITH THIS CAR UNTIL NOW.IT'S BEEN REALLY COLD. ALSO THIS CAR HAS ISSUES WHEN IT RAINS, IT DOESN'T WANT TO START, I HAVE CHECK OUT MANY VIDEOS STATING THE SUNROOF LEAKS OR TUBES FOR SUNROOF GETS CLOGGED AND LEAKS INTO THE BCM OR ECM SYSTEM CAUSES DAMAGE AND DASH LIGHTS. IM NOT A MECHANIC BUT I KNOW THAT THIS IS SOMETHING INFINITI/NISSIAN...

The transmission Valve Assembly Control Module and Vehicle Speed Sensors have both failed. The car will not shift out of 2nd gear and cannot go faster than 40 mph. This is a safety issue. I had my car inspected by a certified mechanic and he diagnosed the problem. He also stated that that he has seen this a lot with Infinitis. I have maintained my car well but this is Not a maintenance issue. There are thousands of infiniti owners online stating that they had the exact same problem. I filed a case with Infiniti #52260861. This is a design flaw with All Infiniti cars and SUV's and it should be a Recall or at a minimum fixed for free by Infiniti. It cost me $3,500 to have my car fixed and this should be paid by Infiniti to me and all other Infiniti owners with this same problem.

Valve body failure

Traction Control did not function when needed. I had my breaks and rotors replaced two days prior to the accident, which may have had an impact on the performance of the vehicle. Insurance representatives did look over the vehicle, as it is now in their possession. However, I do not feel as though they took the time to look into my concerns. There was no warnings on the Dash.

Speed sensor Is faulty on infiniti q50...had it replaced 9/28/22 for 3700.00 now on 3/03/23 I was told I need to replace the transmission for 7300.00 I research speed sensor it seem 2014 to 2015 infiniti q50 are having issues with speed sensor. I have read multiple complaints about this issue. It should be a recall on the speed sensor. Infiniti/Nissan know it I will never purchase a another Infiniti/Nissan vehicle again.

The contact owns a 2014 Infiniti Q50. The contact stated while driving approximately 45 MPH, the vehicle independently decelerated to 10 MPH. The contact depressed the accelerator and observed that the RPMS was elevated however, the vehicle failed to respond. The contact pulled off the road into a parking lot and turned off the vehicle. The contact stated that when she restarted the vehicle, the vehicle jerked while driving and failed to exceed 20 MPH. The contact stated there was no warning light illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the valve body assembly needed to be replaced. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 133,000.

FIRST INSTANCE: WHILE DRIVING ON THE HIGHWAY GOING 60MPH MY CAR POWERED DOWN, PREVENTING ME FROM CONTROLLING THE CAR. THE GAUGES AND LIGHTS INSIDE THE CAR WENT DARK AND MPH WENT TO 0. I LOST ELECTRICAL POWER AND AFTER 1 MINUTE THE CAR IS BACK TO NORMAL. SECOND INSTANCE: AS I WAS PULLING INTO A DRIVEWAY AND WENT OVER A BUMP THE CAR LOST POWER AND POWERED DOWN, I NATURALLY PRESSED THE GAS BEFORE I UNDERSTOOD WHAT WAS WRONG, THE CAR POWERS BACK UP AS I'M PRESSING THE GAS AND CAUSED ME TO ALMOST HIT ANOTHER CAR.

MY POWER STEERING BELT SNAPPED OFF. PRIOR TO THAT, MY BRAKE PEDAL WAS LOOSE ENOUGH TO MOVE IT UP AND DOWN ROUGHLY A 1/4 OF AN INCH WITH MY FOOT. THE ONLY WAY TO ENGAGE THE CRUISE CONTROL WAS TO HOLD THE BRAKE PEDAL UP WITH MY FOOT, THEN IN ORDER TO KEEP THE CRUISE CONTROL ENGAGED WAS TO KEEP HOLDING THE BRAKE PEDAL UP WITH MY FOOT BECAUSE IT WOULD SENSE THAT THE DRIVER SLIGHTLY TAPPED THE BRAKE PEDAL TO DISENGAGE IT IF I STOPPED HOLDING IT UP MANUALLY. I HAD TO HAVE THE BRAKE PEDAL BOLT TIGHTENED. IT HAS HAPPENED AGAIN AND I CAN'T REACH THE BOLT, SO I HAVE TO PAY TO HAVE IT FIXED AGAIN ALONG WITH THE OTHER ISSUES. THE OTHER ISSUE IS MY A/C BLEND DOOR IS NOT OPERATING, WHICH IS CAUSING THE TWO DRIVER SIDE A/C VENTS TO BLOW WARM AIR OUT OF...

I AM EXPERIENCING SOFTWARE RELATED ISSUES THAT HAVE BECOME INCREASINGLY DANGEROUS. IN SUM, THE INFINITI SOFTWARE SHUTS DOWN OR LOCKS UP FORCING ME TO BECOME AN IT TECHNICIAN WHILE DRIVING. WHEN THE SOFTWARE SHUTS DOWN, I LOSE THE SPEEDOMETER, TACHOMETER, CLIMATE CONTROL AND AUDIO CONTROL. HERE'S AN OVERVIEW OF MY EXPERIENCES FOR THE PAST 3 YEARS: RANDOMLY, THE SOFTWARE WILL SHUT DOWN LEAVING ME WITHOUT MY INSTRUMENT PANEL (SPEEDOMETER, TACHOMETER), CLIMATE CONTROL AND AUDIO CONTROL. RANDOMLY, THE SOFTWARE WILL LOCK UP LEAVING ME WITHOUT CLIMATE CONTROL OR AUDIO CONTROL AND THE ONLY RESOLUTION IS TO PULL OVER, SHUT DOWN AND RESTART THE CAR RANDOMLY, CLIMATE CONTROLS ARE SET TO 60 DEGREES W/ AC YET HOT AIR IS BLOWING OUT OF THE VENTS. MOST RECENTLY, THE ONBOARD CLOCK THAT DISPLAYS THE DATE AND TIME WILL RESET TO 01-01-2012 AND THE CLOCK WILL START AT 6:00 AM. THE ONLY RESOLUTION IS TO...

THIS VEHICLE HAS AN ELECTRONIC BRAKING SYSTEM THAT HAS MADE THIS CAR HANDLE ERRATICALLY AND EXTREMELY UNSAFE IN TRAFFIC SITUATIONS. WHILE TRAVELING AT SPEED IF TRAFFIC IN FRONT OF YOU HAPPENS TO BRAKE OR SWERVE IN FRONT OF YOU THIS CAR WILL BRAKE UNCONTROLLABLY WITHOUT NOTICE MAKING IT NEARLY IMPOSSIBLE TO AVOID A COLLISION OR CHANGE LANES TO MANEUVER AROUND ON OBSTACLE OR CAR. MYSELF AND MY WIFE ARE VERY SCARED TO DRIVE THIS CAR AND IN FREEWAY TRAFFIC YOU CANNOT SAFELY CHANGE LANES. WE FEEL IT IS ONLY A MATTER OF TIME BEFORE THIS POORLY DESIGNED SYSTEM WHICH CANNOT BE DISABLED WILL RESULT IN COLLISIONS OR DEATH. THIS HAS HAPPENED MORE THAN A DOZEN TIMES SINCE PURCHASE IN APRIL 2014. WE NO LONGER FEEL SAFE DRIVING THIS CAR.
