2019 INFINITI QX50 Electrical System Problems

The contact owns a 2019 Infiniti QX50. The contact received notification of NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that the vehicle sputtered while the accelerator pedal was depressed before accelerating as needed. The vehicle also failed to start immediately after the initial start-up due to a loss of battery power. The vehicle would be jump-started. The failure occurred intermittently but had become more consistent. The check engine warning light was illuminated. The contact stated that a year before the failure, the engine was making abnormally loud sounds and the vehicle failed to accelerate, with the check engine warning light illuminated. The vehicle was taken to the dealer and was diagnosed and determined that there was hot oil leaking...

In November 2024, my 2019 Infiniti QX50 experienced a sudden and severe mechanical failure while driving. The vehicle unexpectedly lurched forward and then came to a complete stop in traffic. At that point, I was unable to shift the car into neutral or any other gear, which resulted in obstructing traffic. The vehicle was towed to a local mechanic, who diagnosed a total engine failure and quoted repair costs between $15,000 and $20,000 related to a VRC component. Recently, I became aware of a recall concerning similar engine issues affecting certain Infiniti QX50 models. However, my vehicle’s VIN is not listed among those affected by the recall. Given the severity of the failure and the potential safety risks, I would like to formally file a complaint regarding the 2019 Infiniti QX50 to ensure this issue receives proper attention. Thank you for your time and consideration.

Turbo, Rear-Coupler, Engine, Actuator Car was squealing and I was told that the serpentine belt needed to be replaced. Replaced this. Car still squealing and took it back. They replaced the belt, again.. Still squealing, now I am told its the tensioner that needs to be replaced but only Infiniti can do this (belt done at Firestone). At Infiniti - they look at the car and the tensioner is fine. But my turbo is blown. How? So, they replace the turbo and then say the rear coupler needs to be replaced. Repairs done and Infiniti said all fluids are good, everything is great. However, I might see slight smoke and a burning smell for 100-150 miles as theres a thin layer of oil on the turbo that will burn off. Oil change isnt due for 5k miles and I checked before my short road trip - all is good. Past...

All vehicle doors and sometimes lift gate fail to open either by key fob or by indoor automatic door locks. Have to use Valet key to open driver door (alarm does not sound), then enter vehicle and manually unlock or lock desired door. Safety issue because kids can automatically exit or any individual can enter the vehicle unannounced while stopped. Neighbor has exact same vehicle year and model and is experiencing the same issues.

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.

There is a continuous issues with my battery dying. There are multiple malfunction lights showing, particularly the rear collision light. The check engine light is also showing, and I have had an oil change recently. The car breaks on its own. While backing into a space, the steering wheel would not completely turn right until I straightened up the car. Finally. I have had my driver's side car seat repaired three times by the dealership. It works sometimes and not others. Any suggestions on any or all of this would be helpful. Thank you.

The driver seat electric motor has failed on three separate occasions. 7/29/21, mileage 22,984 9/3/21, Mileage 24156 7/12/22, Mileage 34,414 When the electric motor fails the seat can not move forward or back. Depending on the seat position at failure, certain individuals would not be able to reach the pedals to safely drive the vehicle. This could create a serious safety issue requiring some one to drive without reasonable control. Each time the motor failed it was replaced by the dealer. No warning lamps or indication of failure happened prior to the three times of this severe safety failure. As of 6/18/23 the seat has been working properly. I was in contact with a case worker at Infiniti numerous times ( between 7/11/22 and 8/11/22) and she did not think this was a serious problem, as if I was the only person reporting this issue. This was very troubling to...

Multiple repeated problems with electrical system. Repeated crash sensor failure. This mainly happens when it is warm or sunny. The dealership has had the vehicle four times and the problem is still reoccurring. The malfunction light comes on when the car is first started or while driving. The dealership stated that none of the crash sensors work when it is lit. They have replaced the module that was diagnosed to be the problem, however there is still the same issues. They are going to replace the module again. They have replaced a module to control the wipers twice. The wipers still come on randomly when it is sunny, and the delay for the wipers does not work when it is raining. The cruise control stopped working and is throwing codes. This morning`s new warning was shift system malfunction. It's been in three times for the air-conditioner. The cooling fan was...
