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.

Dear infiniti consumer affairs, i am writing to express my concern about the recent transmission failure in my vehicle. This is the second time i have experienced a transmission failure in less than a year. The first transmission failure occurred on around may of 2023. The symptoms were as follows: the transmission gave out while on the highway, causing the vehicle to not start or drive. The transmission would not shift gears at 4000 rpms unless i let off the gas and then gave it gas again. I took my vehicle to the dealership on sometime in may 2024, and they replaced the transmission after they tried to do a valve body that was recommended by the warranty department. Later, i was told that the failure was caused by a faulty transmission and was on recall notice. The second transmission failure occurred on 4/5/2024. The symptoms were as follows: the transmission would not shift gears at 4000 rpms unless i let off the gas and then gave it gas again. The transmission would sometimes slip out of gear while driving. The transmission would make a grinding noise when shifting gears. My wife is taking the vehicle to the dealership on 04/08/2024, and they are currently diagnosing the problem. I am concerned that this is a recurring issue with my vehicle, and i am worried that it will continue to happen. I am also concerned about the safety of my vehicle, the safety of myself my wife and my kids as a transmission failure could cause both her and i to lose control while driving. I am requesting that you investigate this matter and take the necessary steps to resolve the issue. I would like to know what caused the transmission to fail, and i would like to know what steps can be taken to prevent it from happening again. I am also requesting that you provide me with a loaner vehicle while my vehicle is being repaired. My wife needs a vehicle for work, and she cannot afford to be without it. Thank you for your time and attention to this matter. If you need to reach

2017 Infiniti Q50
  • Date of Incident: Mar-06, 2024
  • Date complaint filed: Apr-05, 2024
  • Failed components: 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.

  • Failed components: STRUCTURE:BODY

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

2016 Infiniti QX60
  • Date of Incident: Apr-02, 2024
  • Date complaint filed: Apr-02, 2024
  • Failed components: AIR BAGS

The airbag sensor light is flashing whether a passenger is in the seat or not. Infiniti has refused to investigate the issue and is stating that it is my responsibility to pay for the diagnostics despite the fact that this is an airbag related issue and is possibly related to the 2016 nissan recall.

2014 Infiniti QX60

  • Failed components: AIR BAGS and UNKNOWN OR OTHER

I have an infiniti qx60 that has a hairbag malfunctioning for a long time now. I've taken it to be serviced by infiniti many times. However, they could never fix it. At one point, i decided to leave it alone until the last time i took the car in to be serviced. The person who was helping me noticed that i had two children car seats in the car, so he decided to tell me that this car isn't safe to be driving with young children in it. Don't know what to do since the warranties have expired. Plus, they couldn't fix it when i had warranties on the car. I'm afraid that my family is at risk driving this car. I would love to stop driving this car before something terrible happens to my children. However, it is our only means of getting around right now

2014 Infiniti QX60
  • Date of Incident: Mar-27, 2024
  • Date complaint filed: Mar-30, 2024
  • Failed components: POWER TRAIN

While driving on my regular commute, the car sputtered when shifting gears automatically and stopped being able to accelerate beyond 30mph in the middle of a busy road. When the accelerator was pressed, the motor sounded like it was revving but not accelerating. An electric fire burn smell started to emit and a warning turned on for the first time reading “hybrid system overheated” as well as the check engine light. No issues before this incident. An independent third party service center confirmed that it’s an issue with the transmission. We confirmed that this is a common problem with other qx60s from 2014 that the transmission fails and replacing it does not guarantee that the problem will be fixed long term since the issue is that the original design of the transmission is flawed.
