so after my initial report about my engine catching fire on the highway, I received an invoice for $5,000 for a used engine with 80k miles on it; plus another $2800 for the service fee. I already put down about $3900 for the engine repair. The mechanic sent me pictures of the engine with the holes on it that caused the damage (or the holes might have happened during the fire). I’m attaching photos sent to me, from my mechanic, showing the holes/damage on the engine, for your consideration and a photo of the initial repair bill (including receipt of my deposit) for your review … also, I still need to pay another $4300 to pick it up, but he said my check engine light is still on due to a transmission, that may be related to the valve body failing. What are these qx50s still being sold?? On the car forums and YouTube, there are so many issues with the engines and the transmissions (including the 450k that are currently under investigation). And their consumer affairs dept is extremely hostile about the situation, when you call into the infiniti office/headquarters. These defective engines/ transmissions need to be recalled, as soon as possible. They’re extremely dangerous and Infiniti is not taking responsibility for the problem. Why is the govt not intervening on behalf of the infiniti owners??

ENGINE, FUEL/PROPULSION SYSTEM
There are 2 check engine codes that came up as an issue for my vehicle, out of the blue: P0720 and P0500. I reached out to my mechanic and he couldn't fix it. So my plan was to take it to the dealership at the end of this month; however, while driving the vehicle back from my sister's house, the bottom of the car caught on fire and I had to pull over to jump out the car with my children. Called 911. The police and fire dept came, but the fire had gone out by that time, so the officer had the vehicle towed off the highway. Looked into the issue online and apparently it's very common. One Infiniti dealership said that he fixes about 30 per month. Why didn't Infiniti issue a recall for this very serious, hazardous situation? Where is their due diligence to fix this problem for their customers? Why are they letting so many vehicles fail? What happened to reasonable due care? Is it not enough that they are aware of this issue and won’t recall it, but what about the physical danger that they are putting us in? And the emotional distress they caused my children, having to jump out of their vehicle on a highway in the middle of the night? Doesn’t Infiniti have a minimum safety requirement of due care to mitigate hazards for its customers?

While driving I heard a roaring noise from my engine and my car’s A/C stopped cooling. I have no warning messages from car regarding the engine. The noise only stops once the car is fully powered off. I recorded a video of the noise and alert panel that shows no warnings/issues. Will be contacting my local service department.

ENGINE, POWER TRAIN
About five months ago, while driving on the highway, the care would say it's in Drive, but sounded like it couldn't get out of 1st gear and I'd get high RPMs. Thankfully there was stop-and-go traffic and I didn't have to exit pull off the highway or hit high speeds. I exited at the next exit and, as soon as the car stopped, it wasn't possible to get it into gear. Eventually the car started and I was able to get into gear and drive it using Manual drive mode. Once at the dealership we were told it was a bad VCR and they needed to replace that to get it going. That was around 38,000 miles. This most recent incident, I had just gotten onto the highway when I started to hear a low whiney noise when pressing the accelerator. I only had a few miles till my exit and decided to continue, thinking it might just be debris or something. After exiting, I literally rolled into the gas station because the car, despite being in Drive, was not in gear. The car stalled and I couldn't get it started, or I could get it started, but it refused to go to Neutral to allow me to push it out of the way. Eventually, the car started and I was able to put it into Drive. Thinking it was the same issue, I planned to drive it the 2 miles home. I made it to the first traffic light and the car turned off, leaving the me stranded in the middle lane of the road. I called the police and tow trucks to come help me get the car moved (no one knows how to put the car into an emergency Neutral position including the 2 officers, 4 tow truck drivers and an Infiniti mechanic that was driving by). Eventually the tow truck came and I was able to drop it off at the dealership, who have told me there is "a chunk of bearing material in pan with copper particulates." I'm currently around 40,000 miles.

Engine acceleartion issue. Rpm goes high but car struggle to speed up.. At first it happened when car was at stop light, struggle to move forward.. took to Grubbs infiniti.. At first,dealer could not replicate the issue, but luckily I had taken the video of the issue I had. Than the dealer was finally able to experience the issue themselves and replaced the transmission thinking that was the issue. I took the car after repair and within 3-4 days I had the same issue. This time I was driving in a freeway at 60 mph. When I hit the gas pedal to accelerate faster,the engine RPM went high but instead of speeding up, car felt like slowing down. So i exited the freeway to service road. Once the speed went down to 20mph, it didn't go any higher than that.This time there was a check engine light on I took it back to the dealership .They again could not replicate the issue and just did the ECM software update. I took the car home but after driving less than 20 miles,the car had the same issue. I again took it back to delearship. This time they are replacing something called VCR..Still waiting now

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.

I was driving my vehicle and I stopped at a stop sign. When it was clear I proceeded onto the highway. I took a left at the first exit and could hear a weird knocking noise. I could also feel the car was not accelerating properly. The vehicle was not driving right. I called a tow and took it to a repair shop. The owner of the car shop said that a rod had been blown and I need a new engine. I am 7000 out of my drive train warranty.

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: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
Equipped with ProPILOT Assist and Intelligent Cruise Control inclusive of Lane Keep assist, traffic sign recognition, and Direct Adaptive Steering. Vehicle has just under 60,000 miles and still under warranty When in ProPILOT Assist/Intelligent Cruise Control, when hands leave the steering wheel, car failed to give a dash visual warning, sensory warning, or did not take control of the vehicle to bring it to a safe stop. This of course is a serious safety issue if the driver becomes incapacitated to the point of not being able to respond to the warnings. The car could obviously go through intersections without stopping or possibly get off course resulting in collision with other vehicles, structures or people. This first appeared on interstate highway travel on a trip to Florida in late November and bought in to Smith Infiniti of Hunstville, AL on [XXX] As of this date, [XXX], it has been in service department for nine (9) weeks with no correction of the failure. The dealer and Nissan technical representatives have attempted on numerous occasions and with numerous parts(some replaced 2 times) to fix.

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.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving down an empty road, no one in front of me, beside me, or behind me and the automatic braking system applied itself and slammed on brakes abruptly and beeped twice, without any prior warning or obstruction, causing the car to jolt into braking. I have contacted the dealership regarding this and they are looking at the precollision and emergency braking system next week. There were no prior warnings this braking was occurring. The car has had multiple issues since purchasing including headlight blinking and replacement within the first month of ownership, automatic sunroof needing a replacement because it was installed in the factory wrong, and the door lock actuator not locking/ or unlocking upon clicking lock/unlock. The car has been in and out of the Infiniti dealership in the 4 months since purchase. The car was purchased September 2023, and it is now January 25th, 2024.

I was driving on the highway and the engine started to make a humming sound I would say. Within the next 3 to 4 miles I started losing forward power, and the noise started to get louder. I was afraid my car was going to die on the highway so I stayed in the far right lane so I could coast into the shoulder if I had to. Thankfully, there was an exit and I was able to get off and pull off onto a street at which point it was a louder knocking sound coming from the engine. I drove another block and the check engine light came on and I was getting less power as I pushed the gas pedal. At that point I parked the car and had it towed for repair. This all happened on October 9, 2023. Later that week, I was told by the dealership that I needed a complete new engine that I had thrown a rod in the engine. The car was only four years old and had 75,000 miles on it. Infiniti did help pay part of the bill, but I still had to pay a good portion of the repair and oddly enough the morning after I drove it home, the car would not start. The car was towed back to the dealership. I needed a new starter. That too has since been repaired. I decided to report this after seeing an article this morning regarding an investigation into Nissan for engine failure problems in my model of car.

Last year I had to have the BCM replaced on my infiniti. Here I am a year later and I'm being told that I have to replace the BCM again. The dealer told me that there's water that is literally streaming directly past the module due to the drainage coming from the sunroof. I have no idea why that I happening bring I haven't experienced any leakage from the sunroof. I definitely shouldn't have to replace a BCM 1 year after installation of a new module. Please take look into this issue. I just don't think it's fair that I have to replace another BCM due to the drainage ststem/path on such a luxurious car.
