Selected complaints filed with NHTSA by 2015 Infiniti Q50 owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
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. …
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 .
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.
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.
After starting the car the steering wheel jumps off center and the steering is all over the place. have to start the car again and the steering wheel jumps the other direction. I strongly suggest this is exactly what the June 13, 2016 NHTSA campaign number 16V43000 the software may reduce steering ability and increase risk of crash.the direct steering system my experience an error at vehicle start up altering the vehicle steering responsiveness and turning radius. Exact problem with this car. This car has been recalled for the driveshaft break NHSTA 24V470000
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.
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.
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.
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.
