Filed Aug 23, 2022 · Electrical, Transmission · GA

What component or system failed or malfunctioned, and is it available for inspection upon request? The rear AWD electronic coupler is failing. It is available for inspection. How was your safety or the safety of others put at risk? If it completely fails, the car can become inoperable while driving at any time. I was also told by the dealer that the differential could damage the transmission over time. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealer had diagnosed this issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning or messages. There is grinding when turning at low speeds and when driving sometimes there is a "bump" at around 40 mph. This was first diagnosed by the dealer in 2020 and again in 2022. There was a recall of the rear electronic coupler for the same year, make and model but, Infiniti says that it did not apply to my VIN. The TSB is 12-072C. My research of this issue shows that this issue common for my make, model and year. Clearly, this issue affects many more VINs than, originally recalled. The recall for this issue should be expanded to include my vehicle and extended so that this very expensive repair can be made without cost to me. I purchased this car because, I wanted a safe and reliable car to transport my small children. These critical issues jeopardize the health and safety of my family every day. My car is no longer safe or reliable. Additional, in 2020, at the time that the electronic coupler failure was diagnosed, something related to the CVT was replaced because of a recall. This year, I had to have the the transmission replaced. I now wonder if that could have been related to the CVT issue. My catalytic converters also had to be replaced this year.

July 2022 our 2014 Infiniti QX60 Hybrid at 59,000 miles started making this winding/grinding noise. We took it in and was told the transmission needs to be replaced on a car that is only driven under 7500K miles per year and is in otherwise perfect shape. There is an extended warranty for the non-hybrid models due to a class action suit. This is extremely dangerous and a very costly repair to the tune of $7,500. Infiniti is refusing to repair at this point.

CVT have been told by one Infiniti Dealership the the fluids never need to be flushed, changed or filled. Then I hear about the Transfer Differential which I am assuming is the Transfer Case is leaking and that it would need to be replaced entirely along with the rear coupling costing nearly $10K in repair (Estimated $8,500 alone on these two items). I have found online people and even other Infiniti dealerships where these fluids are flushed and refilled regularly of which in discussing with the dealership these findings, they advised they never have to be flushed, but it is recommended through forums and other dealerships of such. In finding more about the history of my car, I have found that it has NEVER had a flush of the Transfer Differential or CVT or other factors of changing fluids. I advised I recently had a burning smell along with grinding. They only say I need to completely change that out. If I have a leak, then that should have been the first directive in fixing the seal (since this is a sealed compartment). I have 3 times where the power wasn't going to the transmission where I almost got into accidents. Thankfully, the other driver's were able to merge or brake as these were primarily city streets. I found a video where a gentleman had the same issue, the CVT was replaced, and the issue only got worse. How is this allowed or possible?

2014 qx 60 on two separate occasions (dec 18, 2015 and jan 2nd,2016, roughly 2 weeks apart ) the top bolts on the front break calipers fell off causing the caliper to tilt off the rotor. In the first instance, the front driver side wheel started making some grinding noises while driving, as if the break pads were low. The noise started off a being very light when breaking, then continuous grinding. It was not until further inspection that we realized that the entire caliper fallen forward and was rubbing onto the interior of the wheel rim. We made the repair and replaced the bolt and assumed it was a fluke and just one of those random things. Two weeks later, while driving on the freeway with my family in san diego, we started to hear the same noise again. Upon further inspection we discovered that the other front caliper had also become disengaged. The vehicle was towed to the nearest inifinti dealer for inspection. It was a saturday evening and was not till tuesday morning when their service dept replaced the missing bolt and returned the vehicle. After the second incident, I researched the issue online to discover that there was a recall issued on the exact same problem we experienced, with the caliper bolts not being torqued on during the manufacturing process. However after discussing with the dealer and infiniti, I was told the recall did not include the manufacturing date of my vehicle. In the first instance the break pads were still intact with the caliper when it shifted forward off the rotor. In the second instance the break pads actually slipped off the caliper. Photo attached.
