While traveling at highway speed, the vehicle suddenly began slowing down. Pressing the accelerator caused the engine RPM to increase, but the vehicle would not accelerate. I was forced to pull onto the shoulder. After restarting the vehicle, it would no longer move in either forward or reverse and had to be towed.

I purchased my car earlier this year. Paid in full. After having it for about 3 months I had to get a new battery. Now, about 2 months later I’m having to get a new alternator. A licensed car mechanic purchased the battery and put it on. The alternator, I went to the Nissan dealership and they told me it was the alternator. Never any lights or warning lights or labels, with battery I had to boost it, with Alternator it just started making a loud sound. I was afraid if mind and willows(my 6 year old) safety, driving and breaking down on the road, so I took it to Nissan to run a test on it. With no warnongs and this loyd noise i was freaked out. The altinador cost $901.00, just for the part, with a 2 week back order.

​Reporting a severe hydraulic/mechanical braking defect on a 2023 Nissan Altima with only 26,820 miles. Vehicle experiences persistent 'spongy' brake pedal feel, premature metal-on-metal rotor gouging, and severely darkened/degraded brake fluid, indicating a systemic hydraulic component failure or electronic brake-dragging defect. This is a severe safety hazard causing unpredictable stopping distances. ​Authorized dealer (Coral Springs Nissan) refused warranty coverage prior to the May 21, 2023 expiration date and attempted to extort a signed liability/warranty waiver under duress to release my vehicle, which has been documented in writing on the service order and on video footage. ***Manufacturer is actively concealing this safety defect to avoid a mandatory safety recall. I own an identical second 2023 Altima with no such issues, proving a manufacturing defect on this vehicle. I paid $63k for both cars brand new. The only difference is the color. This issue began 2023 just five months after purchase. I called Coral Springs Nissan who told me this was not the brakes but electrical components that are used now. I trusted what they told me. It made sense. How could breaks be like that on a new car? What they needed to tell me was get to the nearest Nissan immediately because they were aware they've been having cars with break issues especially between 2021 and 2023. DO YOU UNDERSTAND THESE ARE BRAKE ISSUES? And what is this I was told that they recently got a judge to sign off and block any more class action lawsuits?? If this was some kind of air-conditioner component and still it wouldn't be fair for people who are trusting in quality. But these are brake issues. These are safety issues! What the hell are they letting these cars out on the road? Issue confirmed by Auto Nation Nissan of Pembroke Pines and Coral Springs Nissan.

P235 /40 R19 92V tires came with 2023 vehicle purchase. Two years following purchase, there are 2 large sidewall cracks at 32,000 miles for the front driver side tire even though the manufacturer mileage warranty is 70,000 miles. One out of four tires exhibiting this issue. Find this to be a huge safety concern as I was unaware of the cracks and there were no air leak/pressure issues sensed.

I took my car into the dealer to ask a question. Upon arriving I tried to open the drivers door after I turned the ignition off to exit the car and the drivers door would not open. The service man tried to open it from the outside with the same results. Finally it opened. It had done this before but I always forgot to tell them when I was at the dealership. The passenger door had done the same thing. The dealership ordered new front door latches for both front doors and replaced them. Yesterday I entered the drivers door to back the car out of my daughter’s garage. I was again unable to get out of the car. The door would only open part way then get stuck. Once outside the car I tried to re-enter the drivers door to leave and I could not get the drivers door open. This is a safety issue. It is scary when you cannot get out of your car.
