2014 INFINITI Q50 Driver assistance Problems

On April 2nd I took my vehicle into the dealer for recall servicing. After leaving the dealer I had my vehicle inspected the next day by a third party repair shop and my brake caliper was missing the main bolt that connects to the brake pad. Brake pads were also less than 5% wear remaining. Myself and others were put in serious danger if my brakes had failed due to this serious oversight and disregard. My suspension also was unsafe in the rear but the dealer carried out a multi point inspection stating everything passed.

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.

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.

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 THEM WHILE EVER OTHER VENT BLOWS ICE COLD . NOT FUN IN THESE INCREDIBLY HOT AND HUMID GEORGIA SUMMERS.

- [ ] 2014 Q50 SPORT VQ3.7VHR PREMIUM BASE WITH 51K MILES. YOU'LL JUST BE DRIVING ALONG AND THE POWER STEERING JUST STOPS WORKING! THE STEERING GETS VERY ROUGH AND THE VEHICLE IS DIFFICULT TO CONTROL, IT'S DONE IT 3-TIMES NOW! ON THE WARNING INDICATOR LIGHTS: 'POWER STEERING WARNING LIGHT' TURNS ON & THE 'VEHICLE DYNAMIC CONTROL' LIGHT ALSO. THEN ON THE VEHICLE INFORMATION DISPLAY: 'CHASSIS CONTROL SYSTEM ERROR' (SEE OWNER'S MANUEL) TURNS ON. YOU TURN THE CAR OFF AND START IT AGAIN AND IT GOES AWAY, SOMETIMES. IT'S HAPPENED THREE TIMES SO FAR, AND NOW IT'S NOT DOING IT IT'S BEEN WORKING FINE FOR TWO DAYS NOW? YOU NEVER KNOW WHEN IT'S GOING TO HAPPEN AND IT'S VERY UNSAFE. THE DEALERSHIP SAID MY BASIC WARRANTY HAS EXPIRED AND I JUST HAVE THE POWER TRAIN WARRANTY LEFT, UNLESS I PURCHASE AN EXTENDED WARRANTY. THIS VEHICLE DOES NOT HAVE DAST TO THE BEST OF MY KNOWLEDGE (IT'S NOT ON THE WINDOW STICKER) AND INFINITI SAYS THERE ARE NO RECALLS ON MY VEHICLE, ONLY 2014'S WITH DAST. I BELIEVE IT NEEDS A SOFTWARE UPDATE.

DURING 20 DEGREE F, I DROVE MY CAR WITH NO ISSUES TO A RETAIL STORE, PARKED IT IN A PARKING LOT. AFTER SHOPPING, RETURNED TO MY CAR & STARTED IT UP, PUT IN REVERSE, STARTED BACKING UP, THEN SEVERAL MALFUNCTION LIGHTS LIT UP ON THE CAR'S DASH & THE STEERING WHEEL LOCKED ALL OF A SUDDEN. I COULD NOT TURN THE STEERING WHEEL. I COULD ONLY MOVE THE CAR FORWARD & BACKWARD & THIS IS ALL WHILE THE CAR IS POWERED ON. I HAD TO HAVE THE CAR TOWED TO THE DEALERSHIP. IN PAST HISTORY, THERE HAS BEEN 2 OTHER STEERING RECALLS (ELECTRIC POWER ASSIST SYSTEM & ADAPTIVE STEERING PARTS) ON THIS SAME MAKE/MODEL,& YEAR. THE DEALERSHIP SERVICE TEAM TOLD ME ON 1/22/19 & THE ISSUE WITH MY CAR WAS THE CHASSIS CONTROL MODULE (THE BRAIN OF THE STEERING WHEEL) & A LANE DEPARTURE MALFUNCTION & THE COST OF REPAIR IS $1600 (NOT COVERED) DESPITE I HAVE AN EXTENDED WARRANTY. THE CHASSIS CONTROL MODULE AS THE BRAIN OF THE STEERING WHEEL CLEARLY RELATES TO THE PREVIOUS STEERING RECALLS (ELECTRIC POWER ASSIST SYSTEM & ADAPTIVE STEERING PARTS) ALONG WITH THE LANE DEPARTURE MALFUNCTION AS DIAGNOSED BY INFINITI DEALER IN SUITLAND, MARYLAND. THE DESCRIPTION OF THE PREVIOUS 2 RECALLS (ELECTRIC POWER ASSIST SYSTEM & ADAPTIVE STEERING PARTS) SAY THAT IN FREEZING CLIMATES, THE ENGINE COMPARTMENT REACHES FREEZING, DISABLING THE POWER STEERING SYSTEM, RESULTING IN A LOSS OF STEERING, INCREASING RISK OF CRASH. AS DIAGNOSED BY INFINITI, DEFINITELY THE CHASSIS CONTROL MODULE & EVEN THE LANE DEPARTURE TECHNOLOGY PARTS HAVE NOT BEEN INCLUDED IN THE PREVIOUS STEERING RECALLS & SHOULD HAVE BEEN. PLEASE ISSUE STEERING RECALLS FOR THE CHASSIS CONTROL MODULE AND LANE DEPARTURE MALFUNCTION PARTS OR JUST THE ENTIRE STEERING SYSTEM. INFINITI IS FIXING MY CAR AT NO CHARGE TO ME AFTER I TOLD THEM ABOUT THE RELATED PREVIOUS STEERING RECALLS. PER THE INTERNET, MANY PEOPLE HAVE EXPERIENCED THIS WITH THIS CAR MODEL. DANGER!!

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 RESET THE DATE AND TIME. THIS SEEMS TO OCCUR EVERY 3 OR 4 WEEKS. WHEN I CALL THE SERVICE DEPARTMENT I'M ASKED TO BRING IN THE VEHICLE ONLY TO BE TOLD THAT ALL UPDATES HAVE BEEN APPLIED AND THE ISSUES CANNOT BE DUPLICATED. I HAVE TAKEN AND POSTED SEVERAL YOUTUBE VIDEOS SHOWING THE PROBLEMS-WHICH I'LL ADMIT IS VERY DANGEROUS TO DO WHILE DRIVING. IN FACT, I FIRMLY BELIEVE THAT WHEN THESE SOFTWARE ISSUES OCCUR, I AM FORCED TO PLAY THE ROLE OF AN IT TECHNICIAN AND TROUBLESHOOT THE ISSUES WHILE DRIVING WHICH IS INCREDIBLY DANGEROUS. THESE ISSUES OCCUR RANDOMLY WHILE DRIVING. THIS IS A LEASE VEHICLE AND I PLAN TO RETURN EARLY AS THE CONTINUED ISSUES PUT ME AND MY FAMILY IN DANGER.

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.
