2018 INFINITI QX30 Electrical System Problems

Hello, My 2018 Infiniti QX30 slips into neutral while driving on the road at high speeds and without any warning. The message on the dash is vague “Service required. Do not shift gears. Visit Dealer.” I almost got into an accident more than once while driving the vehicle as low power to the vehicle accompanies this when it happens. I had absolutely no problems with the vehicle leading up to the first occurrence. In fact, I bought the car with less than 10k miles on it from Infiniti directly, where it was a fleet loner vehicle and well maintained. My car today has 56,000 miles and it is only a 2018. Two months and three car shops later, the issue remains unresolved. Infiniti said at first this was just a dead battery. A day later the issue resurfaced, where I also received a transmission control error. My service tech at...

The auxiliary battery located underneath the interior glove compartment went dead and the car was inoperable. I called Infinity and they would not help me. There was no information relating to this small battery either on internet or Infinity website. I finally had to have a friend drive me to the Coconut Creek Infinity service where they could not give me information but could repair only. The seatbelt on both driver and passenger continually lock up causing undo constriction and stress on eithr passenger. The moonroof electrical retractable interior lining which I have never used maybe 2 times since purchased bunched up two days ago and I cannot get it to close properly. The 2018 Infinity QX30 was purchased December 22, 2020. The warranty is 50,000 miles or 4 years. I have 53,000 miles and Infinity will not honor fixing the moonroof. Many Infinity owners have reported the same moonroof...

The vehicle, with low mileage and no accidents, has had a few engine-related issues over the last few months. Recently, I went to turn it on, and many components of the car wouldn't work (no parking, power steering, engine issues, seats won't move, etc.). I live in a very dangerous city, and my car not working has placed me in a dangerous concern for my well-being. I took it to certified Infiniti dealer who said that the entire electrical harness has been damaged, rendering the vehicle a safety hazard, and quoted me $19,000 in repairs. Infiniti corporate refused to assist in repairing the damage that many people have reported having in this specific Infiniti model.

A variety of dashboard lights illuminated including engine light, ABS, emergency brake failure message etc. Vehicle drove as if power steering had failed. When I brought the car in to the Dealer I was told that the vehicle displayed codes for two concerns: 1) air quality sensor and 2) all 4 wheel speed sensors. The wheel speed sensors had previously been replaced in 2019 while the car was still under warranty. Current estimate for the repair was over $3200. Ultimately, Infiniti corporate paid for the current repair stating these items were “under warranty’ from previous repair. This is the SECOND REPAIR for 4 out of 5 sensors.These failures are red-flagged in the repair estimate as “critical concerns“ by Infiniti service. For context, this is a well-maintained vehicle with under 10,000 miles on it. I am the original owner. My concern is that the underlying cause/s of these failures are not...

TL* THE CONTACT OWNS A 2018 INFINITI QX30. THE CONTACT STATED THAT THE INSTRUMENT PANEL SCREEN BLACKED OUT. THE FAILURE OCCURRED EVERY TIME THE ENGINE WAS STARTED. THE FAILURE EVEN AFFECTED THE BACK UP CAMERA SCREEN. WHEN ATTEMPTING TO REVERSE, THE SCREEN BLACKED OUT AND THEN RETURNED TO NORMAL. THE FAILURE OCCURRED OFTEN. THE VEHICLE WAS TAKEN TO INFINITI OF MASSAPEQUA (4450 SUNRISE HWY, MASSAPEQUA, NY 11758, (516) 797-5200) IT WAS DIAGNOSED THAT AN UPDATE TO THE SCREEN AND CAMERA WAS NEEDED.

PURCHASED THE CAR BRAND NEW TWO MONTHS AGO. DISCOVERED THE LEFT HATCH HARNESS COVER IS CRUSHED. WAS TOLD BY INFINITI REGIONAL MANAGER EVERYTHING ELECTRICAL IS RUN THOROUGH THAT HARNESS AND EVERY TIME THE HATCH IS OPENED AND CLOSED THE WIRING IS GETTING PINCHED. ALREADY HAVE HAD THE CAR TO THE DEALERSHIP FOR BLACK BACKUP SCREEN, AUDIO PROBLEMS, LIGHTS NOT TURNING OFF, RADIO NOT SHUTTING OFF AFTER CAR IS TURNED OFF AND DOOR IS OPENED. WAS TOLD THAT WAS A SOFTWARE PROBLEM AND THAT THE SOFTWARE HAS BEEN UPDATED. INFINITI WON'T REPLACE THE WIRING SINCE NOTHING MAJOR HAS HAPPENED "YET." VERY CONCERNED ABOUT DRIVING THE CAR AND SOMETHING HAPPENING TO THE WIRING SINCE I KNOW IT IS BEING COMPROMISED. CONCERNED ABOUT EVERYTHING FROM A VEHICLE FIRE TO LIGHTING AND SYSTEM CONTROL PROBLEMS.
