2023 Nissan Altima

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.

​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.

During a traffic incident on March 26 2026 I was the driver of the 2023 Nissan Altima SL and I suffered unnecessary bodily injury due to the AEB system. I was in a forward collision, the warning indicator did not go off, and the AEB may have went off after the crash unnecessarily causing major damage to my right shoulder tearing one ligament partially, one ligament completely and tearing my rotator cuff and needing reconstruction and two joints anchored. The impact of the AEB jolt went up my wrist and the force through my shoulder to cause that damage is inexplainable since I was at a complete stop and maybe only one car length away from the other car. I hit my face on the steering wheel. Airbags did not deploy. My son in the passenger seat suffered a concussion as did I. The only thing we can find that could cause this amount of damage is if the AEB decelerated after impact unnecessarily and the airbag did not deploy. That means our bodies were already moving through the impact of the crash only to have been thrust into a second unnecessarily intensely strong AEB jolt. Had the AEB not engaged, we would not have injuries. The warning system failed to activate as well. This system has gone off in error multiple times and the AEB had also engaged several previous times in error when backing out of my driveway. I did not know that it could be an error with the system until I started researching my injuries and learned that this is an issue with this model of Nissan.

The engine mounted high pressure fuel pump became loose and unseated because the engine-side mounting threads failed. The pump lifted off its mounting surface, the head of the engine, and oil came out around the top of the engine. This failure caused sudden loss of engine power and created a potential safety hazard because the vehicle could lose power unexpectedly in traffic and there was fluid leakage in the engine compartment near hot engine components. The problem was confirmed by a Nissan dealer. The dealer inspected the vehicle, documented the failed mounting area on the engine head, and submitted a goodwill warranty claim to Nissan, which was denied. Prior to the failure, there were no 18repairs or service in this area from the factory. Symptoms at the time of failure were loss of power and visible oil leakage from the top/right side of the engine. No warning lamps/messages prior to the mechanical failure. Vehicle had 60,845 miles at the time of failure.

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.

My mechanic noticed oil leaking near the oil pressure switch during a routine oil change. Told me to take it to dealership since I should still be under warranty. When I took it in, they very quickly were able to access that the oil pressure switch was faulty. Mechanic said it is a known problem. If it is a known issue, why not recall it?!
