STEERING
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 .

SERVICE BRAKES
My braking system completely failed while I was driving with no warning of sound or dash safety indicators. The only way I was able to stop my vehicle is by shifting into park while I was in motion. Two days prior to my car losing all ability to brake, my car was routinely serviced by the local dealership. All check points were green, including my brakes. The dealership towed my car back to the service center to inspect. The diagnostics came back as the break actuator unit (computer sensor) shorted which led to no communication to the brake control assist unit (computer sensor). This loss of communication between these sensors basically caused my brake functions to fail. I was fortunate to have been leaving a parking garage and not on the open road. This could have been a fatal incident. The repairs are $7000 of which Infiniti has only offered to cover $3000. This is a safety issue and a loss of faith with Infiniti as a vehicle manufacturer. There needs to be an investigation so no lives are lost. My vehicle is still not fixed.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My car started acting weird, fob wasn’t working correctly, doors repeatedly lock nonstop and drained battery. I took to Infiniti and they said it’s water damage from my sunroof drains. It damaged my BCM. Infiniti has quoted me 3,700 dollars to fix. I’ve done lots of research and this seems to be a very common problem with the Infiniti q50 models. I believe this is a manufactured defect. This could of left me stranded because car wouldn’t crank.

UNKNOWN OR OTHER
Sun roof drain is clogged which has caused my carpets to go wet literally puddles, could potentially damage my electronics in car this is an ongoing problem for thousands of Infinitis. I am in a group on Facebook and I can literally scroll and find hundreds of Infiniti owners complaining about their carpets and how Infiniti dealerships charging thousands of dollars to repair. I’ve been holding off to get this fixed in hopes that I’d find someone to assist me with a lower price but nothing

ELECTRICAL SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
My car would not accelerate over 40 mph randomly after work. Once i noticed and tried to shift to a lower gear the car did not shift gears at all. When these things first happened there was no indicator lights on. The next morning the check engine light came on and the code pulled was P0720. After finding a repair shop to look further into the issue I was advised the car needed a new transmission to fix the issue. $4,000+ for the repair and as i google the issue I see that this is a common issue and it seems to always happen unexpectedly side note: also should be a recall on driver side blend door.. i almost died this summer due to cold air only blowing on one side in the middle of summer in 100• degree weather.

POWER TRAIN
My car has 60,000 miles on it and multiple mechanics as well as the Infiniti dealership tell me it needs a new transmission. $8,000. It will not shift above 2nd gear. I took the valve body and manifold out of the transmission and was surprised to find that the output speed sensor plug is actually a dumby plug that connects to nothing. I've had cars with hundreds of thousands of miles on them still driving with the same transmission they were born with. I've rebuilt a lot of engines, but never had to replace a transmission, especially not after 60,000 miles. Any, I searched the internet and noticed that it's a very common problem with this vehicle.

POWER TRAIN, VEHICLE SPEED CONTROL
The speed sensor on car seems to have failed unexpectedly while driving over a bridge. The car would barely move and could have become a dangerous situation for multiple people had it been typical traffic. The issue seems to be that although the sensors are corrupted, the entire valve body or transmission must be replaced to solve the issue leaving the car inoperable. The car is currently at a repair shop. The engine light did come on shortly after. PLEASE ISSUE RECALL. https://static.nhtsa.gov/odi/tsbs/2019/MC-10168892-0001.pdf

ENGINE, UNKNOWN OR OTHER, VEHICLE SPEED CONTROL
4/16/2023 Sunday 5pm With my wife and daughter in the car, I started the vehicle in my driveway and selected Sport mode as usual. Selected reverse and backed into our turnaround then forward to the end of our driveway. Driveway is approximately 4 car lengths long with a 20 ft long apron turnaround. Almost immediately after braking at the end of the driveway while waiting for passing traffic to exit drive, vehicle suddenly accelerated and I immediately pressed the brake as hard as I could to prevent driving into passing vehicles. I could hear the tires trying to grip/spin while I was fighting to press the brake harder to hold it t back. I then panicked and selected the gear shifter to anything other than drive and it immediately did the same in reverse. After getting in into park, I immediately selected Standard mode and the vehicle performed normal afterwards. There were no warning lights or anything to indicate any issues. Previously I had noticed minor intermittent issues of high RPMs when slowing or braking while in Sport mode but it would immediately correct itself. I have not had a chance to take it for inspection as it's now Monday morning April 17. We were all very shaken. Please advise.

POWER TRAIN
I was driving perfectly fine and i stopped at a red-light. I went to accelerate and the car wouldn't shift out of first gear and then check engine light came on. I pulled over and scanned the codes, it showed code p0500. After bringing to shop and reading thousands of different things from people who own the car online all said the same thing. Transmission valve body is shot. I almost got rear ended when i let off the gas because the engines rpms were so high casuing quick engine braking.

STEERING
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.

The valve body/TCM. Yes the vehicle is available for inspection. The valve body/TCM shorts out on the car unexpectedly and can happen at any time causing the car to be unable to go pass third gear. This can occur on the freeway, or when trying to avoid an accident. This is an known problem with Infiniti’s & there is also an service bulletin associated with this problem. This vehicle has be inspected by the dealership and they confirmed the issue. There are no warning light or and thing prior to this event. After the failure this codes popped up P0720 & P0500. This occurred on Aug 13, 2022

SERVICE BRAKES
Brake Pedal sinks to floor slowly at Red Lights. Randomly vehicle will yank seat belt back when abs module detects no brake fluid pressure once in a blue moon. This is because of the defective ABS module hydraulics leak internally from the factory. As brake fluid heats up the internal leak gets worse. Most likely check ball to pump or out valve leaking by. Model year 2015 for sure. I never got it covered under warranty because the problem starts out very random and takes a lot of time for it to always happen. Dealers will just say no problem found. ABS module cost $1k for me to buy at the dealer. Now I have brakes all the time again no thanks to a factory defect module randomly giving poor to no braking power. Internet forums of 2014-2016 have many people saying the same thing. Not the master cylinder, it is an internally leaking ABS module and will have no codes. Not happy about paying to replace a factory defective part.

UNKNOWN OR OTHER
My vehicle suddenly jumped then accelerated slowly and wouldn't get past 3rd gear while driving on I275 (speed limit 55MPH) proceeded to mechanic, error code 0720 speed sensor output related to transmission. Then was told by Infiniti and another auto body repair shop that it most likely in models 2014-2016 it was a transmission assembly that needed replaced. that Infiniti was given a service bulletin that they should not just replace the speed sensor. I believe this should be a recall. My vehicle has less than 60,000 miles and has been garaged and has had all maintenance completed. This is a safety issue, Infiniti is aware of this and it is also a costly repair anywhere from $2500-$3000. I am asking for a recall of Valve body for Infinite Q50 2014-2016.
