UNKNOWN OR OTHER
Component/system that failed: Panoramic sunroof glass on a 2023 Infiniti QX50. Date of Incident: July 21, 2025 at approximately 8am. Incident description: While my daughter was driving on the interstate at normal speed, the panoramic sunroof suddenly and spontaneously shattered. There was no impact, no visible object, and no warning. The explosion of glass was loud and violent. Safety risk: Thankfully, the sunroof shade was closed at the time of the incident. Had it been open, glass would have rained down inside the cabin, potentially causing serious or even fatal injuries. This was a terrifying failure with high risk to life and safety, particularly at highway speeds. Immediately after the incident I called Infiniti of Memphis where we purchased the vehicle brand new, and it is currently under warranty. I was notified that since there isn’t a current recall anything glass related is not included under warranty and I would need to file a claim under my insurance. We were forced to file a claim through our insurance provider to repair the damage — despite no fault on our part. Warning signs or prior symptoms: There were no warning lights, no abnormal sounds, and no signs of weakness or cracking. The glass failed without warning. Cause: UNKNOWN — but based on public reports, thousands of similar incidents have occurred in other Infiniti and Nissan models. This appears to be part of a known manufacturer defect currently involved in active class-action litigation (Johnson v. Nissan North America) regarding spontaneous sunroof explosions.

FUEL/PROPULSION SYSTEM, ENGINE, UNKNOWN OR OTHER
Vehicle purchased from dealer 3/5/25 (brand new). Noticed struggle to start/shaking vehicle/weak power, within first week. Malfunction indicator light came on 4/15/25, brought into dealership for testing. Data showed fail/pass misfires upwards of 30 times. Diagnosed as fuel injector pump misfire. Part was replaced and picked up the vehicle 5/8/25. Vehicle misfired again on 5/9/25. Brought into dealership for further testing; service advisor stated that the misfire was "likely due to air in the new pump." Noticeable misfire again on 5/27/25, no malfunction indicator light came on, notified service advisor. 5/30/25 vehicle misfired significantly, malfunction indicator light came on again, brought in for service. 6/11/25 service advisor stated they are doing a "pin fit repair" to refit all the connector pins for the ignition coils. I don't feel safe in this car. It's brand new, and should perform as such. When it misfires, I can barely drive past 30mph. It shakes violently, and I don't know whether it is safe to be driving it. Dealership doesn't seem to understand what the actual problem is.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
Multiple electronic and sensor issues with the display screens and infotainment center. Time/time zone change from 12-hour format to military time off and on sometimes multiple times a day. Dash board routinely goes black and not displaying any information. HUD proximity alerts continually go off/flashing when no vehicles are around, tagging the same areas on a specific street that was empty. The sensor system engages the braking system after a faulty proximity alert or a vehicle is outside the normal range. Navigation system map blacking out Inability to disconnect Bluetooth calls using the steering wheel end button and the end button on the screen. The infotainment screen would not respond to menu button for the audio and climate control nor could you access it through the touchscreen menu. The radio would stop working randomly. I had to go to the dealership to get this corrected it would not restart on its own even if it was left overnight. The audio button also would not work. The car would not recognize the profile connected to the key fob routinely. After service, the car took over 8 minutes to lead the infotainment system. The blind spot warning would not function properly continuously. The car was taken into the dealership multiple times, it was assessed by "engineers" 3 times, and it had a total of 3 infotainment systems in this vehicle with 2 replacements since leasing the vehicle. These issues continue to remain and there seems to be nothing that Infiniti can or will do to fix these issues permanently.

ENGINE, POWER TRAIN
Without any warning or indicator light on the dash, the vehicle lost power when pulling out of our driveway - we live on a main road and were very lucky not to be hit by upcoming traffic. The car went into limp mode and would not accelerate past 20mph. We have been fighting with Infiniti for the last three weeks as no one can find the problem and they finally said a new engine was needed. There is on 35,000 miles on this car and we had to fight to have this replacement covered under warranty. Now that parts are back ordered and we are not receiving any help. We are three weeks without a vehicle and have no loaner vehicle. No one at Infiniti can give a timeframe for the resolution of this issue, what caused this issue and we are now very fearful that this will happen again - even with an engine replacement. This was very scary for our family and we are amazed that there was no indicator light or warning. The car didn't make any noises and was running great and then all of a sudden it would not go. Very alarming to say the least!

ENGINE
I purchased this 2021 QX50 Infiniti on [XXX] and have experienced consistent engine knocking. In checking out this problem, I have found that it is apparently a widespread problem with the engine in 2021 QX50 vehicles and can possibly lead to engine lock up and engine failure. The engine thus far has not locked up or failed. I have reported the issue to the dealership, Infiniti of Gwinnett located at 3090 Satellite Blvd, Duluth, GA 30096 and am scheduling to have the dealership investigate the problem. Needless to say this is a major concern and if there are ongoing NHTSA investigations and findings I definitely want to be made aware of same.

UNKNOWN OR OTHER
The car completely stalled while going uphill. It restarted a few minutes after. I received 3 email notifications from Infiniti stating that my engine may have an emission control system malfunction. I took the car into the Infiniti dealership. They stated that the vehicle test was driven for 24 miles. Could not duplicate customers concern and is not stalling when going up hills. Scanned for codes and found multiple past codes. Drove until moniters were set. Rechecked for codes and no codes were found. No further action required, working as factory intent and design. Called Infiniti consumer affairs who stated that they could do nothing else too detect what is wrong with the car.

FORWARD COLLISION AVOIDANCE:SOFTWARE:PEDESTRIAN/CYCLIST/OBJECT/OBSTACLE/ RECOGNITION
The contact owns a 2023 Infiniti QX50. The contact stated while driving 28-29 MPH at nighttime, she noticed an animal in the roadway and decelerated. The contact stated that while the vehicle was approximately 2 ft. away from the animal, the vehicle made a loud sound, and the hood popped up and partially covered the windshield. The contact veered to the side of the road. The contact stated that she sat on a pillow in the front driver's seat, and she was able to drive to her residence at low speed. The vehicle was taken to the dealer the following morning. The dealer informed the contact that the vehicle was designed with the Pop-Up Engine Hood For Pedestrian Protection feature, in which the pedestrian safety sensor in the bumper, signaled the hood to pop up while the vehicle was near the animal on the road. The dealer informed the contact that the vehicle operated as designed and charged a repair fee for the hood pistons replacement. The manufacturer was notified of the failure and sent a field technician, who diagnosed the vehicle and informed the contact that the vehicle operated as designed. However, the contact stated that based on the Owner's Manual, the feature was designed to pop up the hood in the event of a frontal collision with a pedestrian. The contact stated that the vehicle had not collided with the animal. The vehicle was not repaired. The failure mileage was approximately 5,200.

AIR BAGS
As I was entering the freeway, the car was hit by an object which came flying at the vehicle from the adjacent lane. The impact of the object hitting the front bumper of the vehicle caused the hood "airbags" (pedestrian actuator system) to deploy. With the deployment of the hood airbag the hood opened from the back and would not close back up as force of the airbags broke the hinges on the hood. For three days I searched for someone who could fix the vehicle, but no one knew how to do it. Finally, an Infiniti certified collision shop took the vehicle in but advised me they also did not ever repair such issue and would have to receive on-phone training from Infiniti. I proceeded to call Infiniti and file a consumer's report. My car sat in the shop for 3 months as I was told the parts were not available for repairing the vehicle. Finally, the car was completed and returned to me Nov 20. There is a warning light inside vehicle that hood is open. Some of the car's inside lights are not working. The car's headlights are altered and only a very low amount of beam light is now flashing while driving at night. I have made several attempts in my 3 month ordeal to get an appropriate response from Infiniti (asking them why they put a device on a vehicle that no one knows how to work on), but to no avail. I do not feel safe in the vehicle and do not like being Infiniti's guinea pig for a device that no one knew how to work on, and which obviously might not have been repaired correctly judging by an inside light still being on that shows hood open.

ELECTRICAL SYSTEM
A fire spontaneously ignited while the vehicle was turned off and parked in the owner's garage. The fire apparently started in the vehicle's infotainment system. The fire melted all electrical components of the infotainment system and spread throughout the vehicle to the driver and front passenger seats and the front console and dash of the car. Large amounts of soot and debris were deposited throughout the interior of the vehicle. Fortunately, no one was present in the vehicle during the explosion and fire. However, our family was inside the house attached to the garage where the vehicle explosion/fire took place. I immediately contacted the Fire Department when I discovered the fire, and they quickly disconnected the battery and moved the vehicle from the garage. The vehicle was towed to the INFINITI dealership on Burnet Road in Austin, TX where the vehicle is currently located. My insurance carrier, Progressive, inspected the vehicle and determined it to be a total loss. I contacted the INFINITI corporate investigations team in order to provide them an opportunity to inspect the vehicle and determine the cause of the incident. This representative shirked INFINITI's responsibility for the fire and stated it would take 7 to 9 weeks before an INFINITI representative would inspect the vehicle. I deeply want to learn the root cause of this incident to prevent it from happening again. I am angered and saddened by INFINITI's lack of responsibility or care for this grave danger. My insurance carrier will not pay for a rental car for another 7 to 9 weeks. INFINITI should be able to inspect this car imminently, yet refuses to do so. There were no prior warning signs of any risk of explosion/spontaneous combustion/fire. This risk was never presented to me when purchasing the vehicle. Had it been, I would not have purchased the vehicle. We hope the NHTSA can investigate this issue to prevent it from occurring again and hopefully hold INFINITI accountable

While driving the car flashed a red light on the top of the instrument panel, then the car violently stopped in the middle of the road. There were cars behind me, thankfully far enough back they were able to stop and not hit me. The dealership could not find any codes to diagnose the problem. A regional engineer did look at the car and replaced what they think is the issue. No warnings or indications given until the incident occurred.

My sunroof exploded while driving. The sunroof is a panoramic sunroof and only the first section of the roof exploded. I was driving on the interstate on (I-55 South) headed to New Orleans when this happened. The glass exploded and came in the vehicle while we were driving. It was raining at the time as well and we got soak and wet from the rain entering the vehicle. The vehicle was taken to the dealership on 4/17/2023. The service department at the dealership inspected the vehicle and stated it was considered roadway hazard (a rock hit the sunroof) and shattered the glass. I never received any warning lights, messages related to the sunroof. To my knowledge, it is unknown what caused the sunroof to explode.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving on a clear day with no traffic in front of me or debris on the road at approximately 45 mph, a master warning light appeared on my dash with an accompanying warning signal and simultaneously the emergency braking system engaged and brought my vehicle to a sudden stop. As quickly as it started, the warning and braking ceased and left me stunned and terrified. Had I been in traffic or on a highway, I am quite certain that I would have been rear-ended. Luckily, that was not my fate yesterday but this defect is serious and dangerous. I have contacted the dealer and dealer service department. The service department informed me that they could inspect the vehicle in 4 weeks. The dealer said that there are multiple computers in the vehicle and that computers can be glichy. This vehicle has had multiple computer issues since I first leased the car starting approximately 5 months into my lease. I have received a malfunction warning on numerous occasions and have had it in for service where they told me that they inspected the vehicle and all systems seemed to be working fine even though I showed them multiple pictures of the warning. The dealer told me that I should disregard the warning and that customers complain about it often but that it just indicates that there is snow, ice or debris covering the sensors. This is not consistent with my experience.
