2014 INFINITI Q50 Owner Complaints

On April 2nd I took my vehicle into the dealer for recall servicing. After leaving the dealer I had my vehicle inspected the next day by a third party repair shop and my brake caliper was missing the main bolt that connects to the brake pad. Brake pads were also less than 5% wear remaining. Myself and others were put in serious danger if my brakes had failed due to this serious oversight and disregard. My suspension also was unsafe in the rear but the dealer carried out a multi point inspection stating everything passed.

The contact owns a 2014 Infiniti Q50. The contact stated that while driving at an undisclosed speed, the steering wheel felt loose and made an abnormal knocking sound while making a turn.

The vehicle was taken to an independent mechanic, who retrieved DTC: C1130 and C1138. The mechanic informed the contact that the failure could be related to the steering column, but a more detailed inspection of the steering system was needed to confirm the cause of the failure. The vehicle was not repaired. The dealer was contacted but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 73,850.

Car is showing a p0720 code which is an issue with the valve body. The car will not go past 3rd gear. This is a known problem with this vehicle. Infiniti is not issuing a recall. The car won't run and the consumer is having to foot the bill for the repair when they know it's an issue with the vehicle and the transmission.

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. The dealer performed a water test and discovered that there was a leak in the sunroof, which had caused the failure. The mechanic discovered that water had leaked through the firewall in the body control module (BCM), causing the failure. The contact was provided with an estimate, and the vehicle was repaired. The contact stated that after the repair, while the vehicle was idling, the vehicle intermittently jerked. There was no warning light illuminated. The manufacturer was not notified of the failure. The failure mileage was approximately 150,000.

Front and middle crossmember rusted out to the point they have no more structural effects issues discovered while fixing a know issue to these models : rusted out and leaking engine and transmission oils pans I had confirmation from the dealership and other independent repair shop that leaking oils pans are common for those models and can cause engine and transmission failure. For the crossmembers they are important structural components that directly affect suspension/direction and drivetrain secureness. If the plastic shrouds/cover are not taken off during inspection those issues will goes undetected until one of them reaches failure

The transmission Valve Assembly Control Module and Vehicle Speed Sensors have both failed. The car will not shift out of 2nd gear and cannot go faster than 40 mph. This is a safety issue. I had my car inspected by a certified mechanic and he diagnosed the problem. He also stated that that he has seen this a lot with Infinitis. I have maintained my car well but this is Not a maintenance issue. There are thousands of infiniti owners online stating that they had the exact same problem. I filed a case with Infiniti #52260861. This is a design flaw with All Infiniti cars and SUV's and it should be a Recall or at a minimum fixed for free by Infiniti. It cost me $3,500 to have my car fixed and this should be paid by Infiniti to me and all other Infiniti owners with this same problem.

While driving and using the air conditioning system coming out of the vents, the drivers side windows fog up and cannot be cleared with a rag or paper towel. This causes the drivers side windows to become heavily congested causing it virtually impossible to see out of the window and look into the drivers side mirror causing a major blind spot. This is especially troubling in the warmer weather. I’ve avoided two accidents because of the the blind spots this creates not being able to see out of the drivers side window and trying to look into the drivers side mirror to see if the left lane is safe to merge into to.

Transmission will not shift out of 3rd gear. I was driving down the freeway in 7th gear doing 75mph when all of sudden the transmission threw itself into 2nd gear then to 3rd. It felt like I was driving over a very large boulder and my transmission was being ripped out from under the car. Then my check engine light came on. So I had it towed home. I went for a test drive and the car will shift 1st, 2nd then 3rd but won’t go to 4th. It just stays in 3rd, it doesn’t slow down, it continues to rise in rpm and speed but won’t go out of 3rd gear. It also will not go into the manual shift mode either. I have read online about thousands of others with the same exact transmission having the same exact problem. I almost was not able to control my car so it most definitely is a big safety issue. I had autozone run a scan on it and it popped up all of these codes. My dash had zero warning lights at all before the incident happened.

Traction Control did not function when needed. I had my breaks and rotors replaced two days prior to the accident, which may have had an impact on the performance of the vehicle. Insurance representatives did look over the vehicle, as it is now in their possession. However, I do not feel as though they took the time to look into my concerns. There was no warnings on the Dash.

I was driving on the freeway and suddenly my vehicle would not shift into third geer causing the RPM s to go up to 4-5. As I tried to exit the car started shuddering and I was almost hit by multiple cars. I finally was able to exit and stop to park the vehicle. No warning lights came on at anytime. I had it towed to my mechanic and was told that it was the valve body control. My car only has 86k on it and I have taken exceptional care of it performing all maintenace like clockwork. Was told replacement was 8,500.00 for entire part including the housing or 4,500 and use my current housing. My mechanic checked with infinity who said they knew of this issue, but there is no recall and the part is only under warranty for 1 year.
