"takata recall" only owner of 2011 qx56, always on time with proper maintance. After a recall on the timing chain 2 days after picking up vehicle the service engine light came on, I called the dealer they advised it was normal to give it a few days. After 3 days light ses light came off, then about 8 months later the service engine soon light was back, got it checked and it's the catalytic converter.

On a full tank of gas I am only able to get about 200 miles before empty. I recently filled up the gas tank and drove 25 miles and I have 3/4 of a tank of fuel left. I mainly drive in the city, but the recent 25 mile example was highway driving with cruise control on.

Service engine light on. Both catalytic converters needed replacing at 82,000

In june 2017, I had the vehicle into the dealership for the power train recall. In july 2017 (87k miles), I had a 420 bank 1 cat code, and replaced one catalytic converter. In december 2017 (94k miles), the 'check engine soon' light illuminated again, and the 430 code shows the other catalytic converter (bank 2) needs to be replaced. It seems the cats on these vehicles are terrible, and once one goes out, the other fails too. This is very expensive...about $2,000 each in my case. This seems too common based on the reviews I've read online now. I feel like Infiniti should cover the cost of replacing at least one of the cats, but I was denied assistance.

Fuel line failure: a fuel line fitting/clamp on back side of engine (drivers side) is streaming fuel at a rate of approximately 1/2 cup per minute. While bring my kids to school this morning, I noticed a strong smell of gasoline, so I checked underneath and saw gas steadily streaming from the car and forming a puddles,I am having the car towed to dealer's garage for repair later this week. The car has never been in an accident. The fuel line leak may be related Infiniti's recall: NHTSA id: 14v-683.

The service engine light came on and the vehicle was checked by Infiniti service. The right side catalytic converter failed. We repaired that (about 2 weeks ago). Today, the same service engine light came on and it is the left catalytic converter. The total amount spent to repair both of the catalytic converters will be over three thousand dollars. From speaking to the mechanic and researching online, it appears that the catalytic converters failing on this vehicle is a prevalent problem. This is a very expensive issue to fix and it seems like many people are experiencing this issue. Although there may not be a large number of people reporting this issue on this site, it appears that this is an issue that many people are experiencing based on the online forums I have read.

Timing chain started rattling @ 125,000 miles.. However, my VIN shows no recall for my car. Cats went bad, had to be replaced and now need to be replaced again. Yet no recall on my car. The battery constantly goes dead in the car. I bought a new infinity battery in the car the same thing happened. You can reproduce this problem by sitting in the car listening to the radio for 30 minutes. I was sitting in the car listening radio and the car battery went dead and the car shut off. This is a huge issue, the qx56 is a 8 cylinder car. It does not charge very easily. I have to carry a battery charger in my car. I have been stranded several times in the last year. I have taken the car to infinity and they claim nothing is wrong with the car. Since it is a big car the battery drain quickly.

The air suspensions of this SUV goes out. The white paint for my 2011 gx56 is peeling all over the vehicle. And needs to be painted asap. This vehicle is a luxury truck that's peeling bad.

Problems with the timing belt chain on newer model Infiniti qx56. Problem of car making whistling noise appeared early after purchase and intermittently thereafter but became prominent in july 2011. Appears to be a recurring problem with this vehicle model. Dealer had to replace the entire engine on the vehicle to address the issue. However, we believe the underlying defect in the timing belt chain will continue to occur and that there is the potential the engine could fail and cause a major accident(s) and/or fatalit(ies). *tr

Traveling at 1 MPH, my 2011 Infiniti qx56 bumped another vehicle. There was no damage to either vehicle, but my driver airbag deployed. Infiniti is refusing to look at the vehicle unless my insurance company asks them to. I feel this low speed deployment is from a defect in this week old vehicle, but cannot get help. I am concerned Infiniti is attempting to ignore the problem and brush it under the rug. *tr
