Direct adaptive steering experienceing at start up altering the vehicles steering and responsiveness and turning radius does not work and is increasing the risk of a crash. Very unsafe to drive. There is a recall 16v430000 on this very problem. Have been told by dealership and nissan motors that my car is not on the recall and I will have to pay my self to get fixed and to see if that is the problem. Reading the federal safety agency campaign number:16v430000 this is the exact problem with the direct adaptive steering system on this car. I believe this should be covered by the recall!

DAS issue that I have been dealing with for two months now, issue is still not resolved even after taking out a personal loan for 6k to fix the modules at Douglas Infiniti, waited weeks for the modules, they replaced the modules, did the calibration but a new issue is happening where I'm losing control for a split second and the car would either pull to the left or right egregiously. I took it to back to Douglas Infiniti for the issue, they found code C13E9-00, cleared the code and did the calibration again only for the issue to happen again once I was close to getting home. Spoke with Martin the advisor and he is saying that he thinks its an issue with the rack and pinion and not a software issue. I bought the rack and pinion from infiniti's wholesale direct website, the rack and pinion came from Infiniti of Winston Salem, so it's an OEM rack and pinion, he said I should take it back to the shop where I got it installed and have them check their work, even though they were able to calibrate the system once the new modules were installed, certify their work and give me back to the keys to the car only for the issue to happen again. Took it back to DriveWorks Auto Center in Union, NJ and they couldn't find any issue with the rack & pinion, said I need a wheel alignment thought, went and got a wheel alignment. Driving home from work yesterday on [XXX] going down the hill and the car steering went out momentarily and the car started pulling to the right, straightened the wheel and now I was swaying to the right. I have a case open with Infiniti Consumer Affairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.
