2015 INFINITI Q50 Steering Problems

Was making a left turn when the steering stopped working and the motor lost power, the adaptive steering quit working after approximately 15 mins. I started the car and it was working. Went a half mile made a right turn and it went out again. Shut off the motor tried to start it and could not. 20 mins later it started and has been working since. Dealer couldn't find the problem and wouldn't fix it, they also said that their were no recalls but I know that is not true. Infiniti had a law suit brought against them for the adaptive steering issue. If they fixed it why doesn't it work right.

Unknown. Started to make left turn steering made loud banging noise then lost all power. Stepped on gas pedal would not go lost steering control and coasted to a stop. Adaptive steering went out. Almost got hit by on coming traffic.

Adaptive steering clicks and looses control. Steering wheel jerks back when self aligning. There was a recall for this I believe in June 2016. For 2015 infinity Q50’s but my VIN says that it wasn’t recalled but is the exact description of what is happening.

Air bag light suddenly said “passenger airbag off”. Don’t have to brake to switch gears. Steering at times feels a bit off.

Transmission, Transmission Valve body, speed sensors. After transmission shifting issues while traveling the interstate I had to have the car towed to the dealership. After the multi point inspection was performed serveral recommended itmes related to the ongoing performance and SAFETY of the vehicle listed below: Transmission $10,446.65 Transmission Valve Body $3693.92 The diagnostic code P0720. Attached is the service bulleting stating they know this will happen and when it does here's how to fix it. Yet they have never recalled the defective transmission. When I contact Infiniti consumer affairs they simply say that they cannot help me because the vehicle does not have warranty. If i had warranty then I would not be reaching out to them for assistance in replacing the transmission.

Sitting in parking lot when a malfunction warning popped up with the dashboard lit up. Steering wheel, traction control, front and rear collision control and chassis system control system error. Had car towed to the dealership to find out it was DAST Steering control units. EPS/DAST 3 DTC C13D5-00 Control module, Chassis Control DTC C1B90-00 DAST System, DAST 1 DTC C13E9-00 Booting Angle Processing, DAST 1 DTC C13EB-00 Booting Angle Processing, DAST 2 DTC C13EB-00 Booting Angle Processing.

Power steering failed while driving in parking lot looking for parking spot. Unable to turn wheel without hitting parked car. I was able to drive to end of the lot where there were less cars. Noticed that I was able to turn wheel so long as didn’t step on brakes. The steering wheel was also off alignment. This happed on a Saturday evening, next day car was fine all the warning were off. Spoke to service person explained what happened. He basically said if the car is running fine they can check it out but may not find the problem. Since the car was running fine until it wasn’t. Car was parked in garage turned on the car all warning lights go on. Made appointment for 4/3/24 drove car to dealership which is not to far. The warning lights still on and no power steering. Analysis many DTC codes found related to this system:B2512 4WAS SIG: C1B9000 DAST SYSTEM: C1138 4WAS CIRCUIT & C1A04 ABS/TCS/VDC CIRC. Correction Recommended to perform DAST calibration first before performing further diagnosis. COST $539.15 . They also did Multi-Point Inspection items requiring immediate attention Engine Air Filter COST $94.99 GRAND TOTAL $641.64 out of pocket. 4/3/24 picked up car. On that evening drove the car and as I’m pulling up on drive way power steering goes out again. I managed to get the car in garage. Once I’m in push button to close garage doesn’t work and car dies no power at all. Able to get car started by playing with battery cables. On dealership notes car was there 30 miles ago. Now they say wrong battery size. That battery was replaced by them on 2/28/22. Also the battery just past Multi-Point 2 days ago.New battery cost $232.78 now out of pocket $874.42.This is now 4/10/24. Drove that evening and front splash guard fall off had to tie wrap to hold whatever pieces are left. Took it to dealership they took no responsibility. I will need to replace it. I have all my receipts from them they are the only ones who have worked on my vehicle.

Car pulled to the left unexpectedly and constantly for like 5 mins staright then it corrected it self.

Car starts up and a little like the battery is having issues with loss of power. The dash board then shows multiple warning lights such as a batter, steering, and stability control. I turn the car back off and then back on and the steering light stayed on. The steering wheel is stuck but the car still moves forward and backwards with very stiff steering. In the past I had the issue checked by getting the steering wheel fluid exchanged and had multiple alignments since . The car would show signs of stiff steering when parking it will get wonky and like won’t move and bumping into a curb with the rear wheels will trigger it every once in a while. The steering has been an ongoing issue for the last year and I can’t figure out what it is but I did find out by Google searching that there was a recall on other models like mine with powering steering assist .

I was driving and tried to turn but had lost complete control of the steering and hit the curb infront. Luckily i was only going 5-10 MPH so the impact was not terrible. My biggest concern is a lot of times my mother drives that car who is permanently disabled in one hand so I can only fear what might happen if she was the one driving the car.

My steering wheel heater used to work normally, meaning an acceptable temperature, and divided evenly through my steering wheel. It is now only getting SUPER hot, to where I cannot even hold it, on the bottom left part of the steering wheel. The rest of the steering wheel is cool.

It seem as the chassis control system continues to fail even after I had the entire system replaced at Austin Infiniti. It seem as it is electrical that doesn't occur all the time but occurs randomly even while driving. It make the steering lock up after a stiff pull at random times then cause all the other system to act up such as the collision or lane departure. It states error code chassis control system and Infiniti each time after taking it back for a warranty job they decline after having footage that I take when the error occurs with my steering wheel in a different angle for forward driving. This is why I am writing this if it can resolve others who have ran into this occurrences when Austin Infiniti has told me they have ran into this before for another customer but luckily they car was under the manufacturer warranty and mine carshield. Will be dropping off again in March for my appointment since it seem to be coming on more often hoping the warranty company can inspect the error this time to repair it.

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.

LOSS OF STEERING CONTROL AFTER START OF CAR, STEERING PULLS HARD TO ONE SIDE. HAS HAPPENED AT LEAST 4 TIMES. IT IS MY UNDERSTANDING THAT OTHER Q 50 HAVE BEEN RECALLED FOR THIS INTERMITTENT STEERING PROBLEM. I DO HAVE VIDEO OF THE LAST OCCURRENCE, BUT IT EXCEEDS 5MB.

Mileage: 41,000

TURNED THE VEHICLE ON, PULLED OUT OF PARKING SPOT AND HEARD A NOISE FROM THE FRONT OF THE VEHICLE AS STEERING WHEEL WAS TURNED. THE STEERING WAS VERY TIGHT AND THE VEHICLE WAS DIFFICULT TO MANEUVER. AS THE SPEED INCREASED, THE STEERING LOOSENED, AND AS THE VEHICLE DECELERATED, THE VEHICLE BECAME NEARLY IMPOSSIBLE TO MANEUVER. THE POWER STEERING FLUID IS FULL, AND THE VEHICLE APPEARED TO BE IN GOOD CONDITION. THERE WERE NO ACCIDENTS OR INCIDENTS PRIOR TO THIS ISSUE, AND THE VEHICLE OPERATED WITHOUT ISSUE PRIOR TO THIS INCIDENT.

Mileage: 46,000

MY VEHICLE HAS AN OPTIONAL TECH PACKAGE THAT PROVIDES FORWARD BRAKING, LANE DEPARTURE AND BACKUP BRAKING. APPARENTLY WHEN I HIT A POTHOLE, THESE SAFETY FEATURES OCCASIONALLY TURN OFF. IV'E HAD THESE CAR FOR 4 1/2 YEARS AND BECAME AWARE OF THIS PROBLEM ABOUT 6 MONTHS AGO. I'M HAVE BECOME DEPENDENT ON THESE SAFETY ENHANCEMENTS AND NO-LONGER FEEL COMFORTABLE WHEN DRIVING. I HAVE COMPLAINED THE DEALERSHIP SINCE NOVEMBER 19 AND STILL HAVE NOT RECEIVED A POSITIVE RESPONSE ALL I WANT IS TO HAVE A WORKING SAFETY SYSTEM..

Mileage: 17,000

THERE ARE TIME WHEN I GO TO TURN MY STEERING WHEEL I AM GIVING MORE FORCE TO TURN THE CAR AND MY CAR SHOWS NO MECHANICAL DAMAGE OR ANYTHING BUT WHEN I TURN THE WHEEL IT STIFFENS UP A LOT AND IT IS NOT SMOOTH TO TURN ESPECIALLY WHEN I AM MAKING TURNS I SEE THIS AND IT IS WHEN I'M IN THE CITY MOSTLY.

CARS STEERING WHEEL WILL CLUNK AND TURN OPPOSITE DIRECTIONS WILL REVERSING INTO PARKING SPOTS OR SLOWLY TAKING OFF FROM BEING STATIONARY. THIS HAS HAPPENED A FEW TIMES OVER THE COURSE OF 4 MONTHS AND I'VE ONLY HAD THE CAR FOR ABOUT 7. LAST NIGHT I WAS PULLING INTO MY DRIVEWAY AND THE STEERING WHEEL SHARPLY TURNED RIGHT, I SHIFTED THE CAR TO PARK, AND THE CAR JUST COMPLETELY DIED. NOTHING HAD WORKED AT THAT POINT, NO LIGHTS, IGNITION, KEYS, NOTHING. I GOT OUT OF THE CAR AND SHUT THE DRIVER DOOR AND EVERYTHING TURNED BACK ON EXCEPT NOW THE STEERING WHEEL WON'T TURN UNLESS USING UNREASONABLE FORCE. POWER STEERING LIGHT ILLUMINATED, CHASSIS CONTROL. THIS HAS ALSO HAPPENED ON MY TEST DRIVE WITH THE VEHICLE IN DECEMBER OF 2018 WITH 54,000 MILES BEFORE PURCHASING . THE STEERING WHEEL SLIGHTLY TWITCHED AND I EXPRESSED MY CONCERN TO THE DEALER AND HE SAID IT WAS NORMAL. IT WAS VERY LIGHTLY THAT YOU COULD HARDLY TELL IT DID IT SO I WASN'T SUSPICIOUS OF THE CAR HAVING PROBLEMS. THIS HAS NOT ALMOST CAUSED IN ACCIDENTS BUT I HAVE A 3 MONTH OLD GIRL AND THIS IS VERY UNSAFE AND ALSO MY ONLY CAR.

CAR PULLS TO THE LEFT ON ITS OWN , HAPPENS PRETTY OFTEN. THE FORCE IS SO BAD THAT I CAN BERELY KEEP THE CAR ON THE ROAD. HAVE TAKEN THE CAR TO DEALER 6 TIMES THEY CALLED INFINITI MANUFACTURER ENGINEER AND HE SAID THEY COULD NOT FIND THE PROBLEM I HAVE SEVERAL VIDEOS I AM AFRAID TO DRIVE THIS CAR. THE CAR DOES THAT FEW MINS AFTER STARTING THE CAR IT PULLS TO THE LEFT WITH A HARD FORCE FOR LIKE 2-3 MINS THAN BECOMES NORMAL LIKE NOTHING EVER HAPPENED.

LACK OF STEERING CONTROL, RESPONSIVENESS RESULTING IN DELAYED TURNING. I WAS DRIVING ON A RESIDENTIAL STREET, AND HAD A DELAYED TURN RESULTING IN AN ACCIDENT.

Mileage: 4,200

THE VEHICLE IS ON A NATIONAL DO NOT SELL LIST, THIS IS AWFUL FOR RESALE VALUE!!!

FIRST OF ALL THIS IS THE SECOND INSTANCE FOR THIS, THE FIRST TIME IT HAPPENED THE DEALER DISMISSED AS THE DRIVE ASSIST BEHAVING NORMALLY. HOWEVER WHILE MY WIFE WAS TAKING OUR SON TO SCHOOL THIS MORNING 04-15-16, THE STEERING WHEEL DECIDED TO TURN TO THE RIGHT SUDDENLY AT 45MPH, LUCKILY MY WIFE WAS ABLE TO CORRECT FOR IT BY STEERING IN THE OPPOSITE DIRECTION. SHE THEN CALLED ME AND SAID THAT SOMETHING IS WRONG WITH THE STEERING OF THE CAR AND THAT IT KEPT WAS PULLING TO RIGHT HARD. I TOLD HER TO FIND A SAFE PLACE TO PULL OVER AND TURN THE CAR OFF AND THEN START IT AGAIN. AFTER SHE WAS ABLE TO STOP SOMEWHERE SAFELY SHE TURNED THE CAR OFF AND THEN RESTARTED IT AND THE STEERING SEEMED NORMAL. I HAVE EXPRESSED MY CONCERNS OF THE SAFETY OF THE DRIVE BY WIRE AND STEERING ASSIST TO THE DEALER WE BOUGHT IT FROM AND TO INFINITI CONSUMER AFFAIRS WHEN THIS HAPPENED THE FIRST WEEK OF OWNING THE CAR, NOW THAT IT HAS HAPPENED AGAIN HAVE NO CONFIDENCE IN THE SAFETY OF THIS CAR, ESPECIALLY WITH MY 3 YEAR OLD IN IT. I CAN NOT EXPRESS TO THE WORRY I GO THROUGH EVERY TIME THEY DRIVE THE CAR. I INTEND ON CONTACTING BOTH THE DEALER AND INFINITY CONSUMER AFFAIRS BUT I KNOW WHAT I CAN EXPECT FROM THEM, NEXT STEP IS CONTACTING A LEMON LAW LAWYER FRO FURTHER ADVICE.

ON NUMEROUS OCCASIONS WHILE IN MOTION AT VARIOUS SPEEDS THE VEHICLE WILL AUDIBLY ALERT, BRAKE, STEER, AND DEADEN THROTTLE RESPONSE. THESE ARE RELATED TO ENHANCED SAFETY FEATURES OF THE VEHICLE. THE PROBLEM IS THAT THESE OCCUR WHEN THERE IS NOTHING TO AVOID OR ANY DANGER PRESENT. THESE HAVE OCCURRED AT HIGH SPEEDS AND IN SITUATIONS WHERE THEY COULD HAVE CAUSED AN ACCIDENT. MY LOCAL DEALERSHIP BLAMED ALL ISSUES ON THE PLACEMENT OF AN EZ PASS TRANSPONDER. I FIND THIS TO BE COMPLETELY ABSURD. INFINITI CUSTOMER CARE WILL NOT ASSIST. I HAVE DISABLED ALL OF THESE SYSTEMS TO AVOID POTENTIALLY DANGEROUS SITUATIONS. I NOTE IN THE DATES THAT THIS OCCURED ON 10/10/15, HOWEVER THERE HAVE BEEN MULTIPLE INSTANCES. ON 10/10/15 THE VEHICLE STEERING HAD TO BE HELD AT 30-45 DEGREES TO THE LEFT TO KEEP THE VEHICLE IN A STRAIGHT LINE.

Mileage: 3,000

THE VEHICLE SUDDENLY PULLS VERY HARD TO THE RIGHT REQUIRING FORCE TO KEEP IN A STRAIGHT LINE. THE VEHICLE DID NOT EXPERIENCE ANY ALIGNMENT ALTERING POTHOLES OR ROAD BUMPS. THIS IS A DANGEROUS SOFTWARE MALFUNCTION WITH THE DAS. I AM VERY LUCKY THIS OCCURRED AT LOW SPEED AND WITHOUT MY CHILDREN IN THE CAR.

Mileage: 2,300

WHILE DRIVING ON THE HIGHWAY 60 PLUS MPH, I LOST CONTROL OF THE VEHICLE. I TURNED THE STEERING WHEEL LEFT AND THE CAR WENT RIGHT. THIS OCCURRED TWICE ON TWO SEPARATE DAYS. THIS IS A MAJOR SAFETY ISSUE. ...UPDATED 12/03/15 *BF UPDATED 10/30/2017*JS
