POWER TRAIN
Transmission will not shift out of 3rd gear. I was driving down the freeway in 7th gear doing 75mph when all of sudden the transmission threw itself into 2nd gear then to 3rd. It felt like I was driving over a very large boulder and my transmission was being ripped out from under the car. Then my check engine light came on. So I had it towed home. I went for a test drive and the car will shift 1st, 2nd then 3rd but won’t go to 4th. It just stays in 3rd, it doesn’t slow down, it continues to rise in rpm and speed but won’t go out of 3rd gear. It also will not go into the manual shift mode either. I have read online about thousands of others with the same exact transmission having the same exact problem. I almost was not able to control my car so it most definitely is a big safety issue. I had autozone run a scan on it and it popped up all of these codes. My dash had zero warning lights at all before the incident happened.

STEERING, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

My engine light came on at 115,946 miles causing my vehicle not to accelerate or shift properly which could have resulted in a accident. The vehicle was diagnosed at local Nissan dealership with code P0720 and P0500 stating vehicle need a transmission. Prior to this diagnose this vehicle was diagnose twice by a Nissan and Infiniti dealership concerning the shifting and acceleration issues but could not duplicate the issue at the time. I see where numerous car buyers are stating they’re having the same issues with the Infiniti brand at low miles and high miles.

AIR BAGS
The airbag light came on for the passenger side. The dealership said I had to pay $246 to find out what the problem is. They told me the entire seat/airbag structure needed to be replaced at a cost of $6k-$13k. I searched the problem online and there is the exact recall for this car/problem but not my vehicle. I don’t feel like I should be responsible for a safety issue in a 7 year old car. I believe this model should be included in the recall. I also am requesting the $246 be refunded.

the miles on the car were changed and trying to sell without the information aswell as the car is trying to get sold as a salvage title car without dealer license on facebook but they tempered with the miles on the car making it look like it only has 30k when in reality it was last reported to have 180k

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.

ENGINE
The engine in this car needs to be replaced. The main bearing is failing, head gasket blew, and coolant has leaked into the engine. About August 30, 2023 I had a sudden coolant loss followed by temperature spike. If the engine had seized while driving, it could have caused a loss of power and locked up the drive train. After sitting while i tried to determine the coolant loss and temp spike, i made arrangements with a local infiniti dealer about jan 9 with a drop off date of jan 22 or 23. The dealer has confirmed the bearing, oil, coolant issue. There were no warning lights or check engine lights before the issue occurred.

UNKNOWN OR OTHER
I was in my car waiting my for complex security gate to open when I heard a loud noise. I got out of my car to see what it was and turns out my sunroof exploded. For no reason. No rock or item hit my car nor was the car in motion. It was also not from the heat as it was 60 degrees outside. I called my warranty and they refuse to cover it because it is glass. I am reading many others with this same issue. How does a 6 year old car have the sunroof explode??

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.

The car was involved in an accident, after the shop checked the vehicle it was brought to our attention that the air bags got stuck and did not deploy because of a malfunction. I was not aware of this which it could put my son in really dangerous situation. I checked for recalls and none has been open for this particular car.
