Owner reports
Selected complaints filed with NHTSA by 2014 Infiniti Q50 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2014 Infiniti Q50. The contact stated that while driving at various speeds, the message "No Key Detected" was displayed. The contact waved the key fob around the START/STOP button, and the message ceased. The contact stated that the light around the START/STOP button was orange, but was green before the failure. One day, while driving the vehicle, the engine failed to shut off after shifting into park(P) and pressing the START/STOP button. The contact made several attempts to turn off the vehicle. The message to "Visit the Dealer" was displayed. The vehicle was taken to several independent mechanics before finding a mechanic who was able to turn off the vehicle by removing the starter fuse. The mechanic advised the contact to tow the vehicle to the dealer. …
A short in the hybrid system's fuse relay caused the air conditioning control unit and compressor to fail. This further shorted out the hybrid junction box causing the hybrid battery recharge and power management system to malfunction. Gas mileage was very adversely affected and the hybrid system would have eventually failed causing a potential safety issue where the vehicle could lose propulsion suddenly while driving.
Our front right bumper was just slightly damaged when back out of our garage. It was very mild cosmetic damage that occurred at only a speed of perhaps 5 MPH. Original body work estimates came in at $2,000 only to spiral out of control with the steering modules being replaced them steering rack before the car was ultimately totaled as the steering programming was still off. Upon research we found out that this particular model was plagued with electronic steering issues which appeared to be addressed under multiple recalls. The insurance company stated that they have videos of the steering wheel going crazy back and forth wildly after the modules were replaced. I am extremely concerned that such an insignificant bump could not only result in totaling a vehicle but could jeopardize a driver's safety with the steering issues.
The top of my drivers side heated seat got so hot it melted the leather without the heated button even being pushed in the on position.
First incident of this happening was during a trip to white plains, where the navi and info touch system would randomly restart. Within the 45 minute drive the system has restarted twice on me, and at the most inconvenient times, where I really needed to see the directions. I didn't pay it any mind at first since it was essentially an electronic item and like all electronics, it reboots from time to time. But needless to say that it has been more then inconvenient, to the point where it is useless. I have used the navi system on my phone more then the navi system itself, because it is unreliable! I have brought it to the dealership twice already and according to the dealership "if we can't reproduce the issue, Infiniti won't troubleshoot it". Even though I have video footages of the issue happening as I was driving, in different time stamps and locations. …
Backup camera sometimes fails to initialize after starting the car. Sometimes it doesn't come on at all (especially at night), and sometimes it comes on so dim at night that it's impossible to see anything (there seems to be a day [dim] and night [bright] brigness/contrast mode and it's like the day mode comes on even though it's night). Backup camera also always takes at least 30 seconds after the car starts up to show the gridlines and "check your surroundings" warning message. Well beyond the 6 secs recommended by the NHTSA. Infiniti claims that the camera is operating as designed and can take up to 90 seconds to load. I never have gridlines or the proper warning lines when I back out of a space (the system is simply too slow). This is very concerning to me as the camera does not always work at night when I need it the most. …
- [ ] 2014 Q50 sport vq3.7vhr premium base with 51K miles. You'll just be driving along and the power steering just stops working! The steering gets very rough and the vehicle is difficult to control, it's done it 3-times now! On the warning indicator lights: 'power steering warning light' turns on & the 'vehicle dynamic control' light also. Then on the vehicle information display: 'chassis control system error' (see owner's manuel) turns on. You turn the car off and start it again and it goes away, sometimes. It's happened three times so far, and now it's not doing it it's been working fine for two days now? You never know when it's going to happen and it's very unsafe. The dealership said my basic warranty has expired and I just have the power train warranty left, unless I purchase an extended warranty. …
2014 q50s shut off both the navigation screen and the intouch screen which controls the climate control, defroster, radio, cabin lighting settings, automatic wiper settings, etc. In the car. Only way to get them to restart and function was to pull over and re-start the car. Infiniti sent an engineer to my retailer and told me my phones Bluetooth is not compatible with intouch, nor the Bluetooth functionality of the car. As such, it is creating this "glitch" in the system. I was never advised at time of purchase my phone was not compatible and would create such an issue. If you do not have a Nissan north America approved device for Bluetooth it could apparently create this problem. Note: phones on the approved list are at least 3 years old, so if you bought a phone in the last 3 years it likely is not approved for use. …
I live in a one family house with an attached garage. My wife parked the car,with 1/3 of a tank of gas,in our garage about 6:30 pm on August 17. She thought she had pushed the button to turn off the engine, and exited the car taking the Smart key with her. About 9 the next morning, while walking my dog, I felt heat coming from the garage and opened the door. It was very hot to touch. I then touched the car and burned my hand. I called our local fire department and they pulled the car out of the garage. The car was so hot, a cd in the door compartment melted. The firemen explained that my wife and I and our dog, could very easily have been killed by carbon monoxide and the entire structure could have burned from the heat. I have since learned that what happened to me is a common occurrence and people have died as a result. …
Q50 backup camera malfunction. After 3 years and 8 months (33000 miles) the backup camera display stopped working properly, it often just shows a black or white screen with no view behind the car when put in reverse, even after waiting 60 or more seconds for the apps to load or rebooting the system as suggested by the dealer. My Infiniti dealer replaced the display module but it didn't help. The problem happens day or night when putting the car in reverse. The dealer says according to the Infiniti tech support staff there is no solution to this problem. Infiniti consumer affairs says according to their tech, "it is a normal characteristic of the vehicle". Its normal for the camera not to work because its happened to a lot of Q50 vehicles. They refuse to fix the problem under warranty. This is second Infiniti I have owned but it is the last. They don't honor the factory warranty. …
