In terms of being a full-size truck, the Nissan Titan has never been the most popular. But that does not necessarily mean it’s not a worthy pickup. It’s just an indication that a lot of the time, folks look to brands like Ford, Ram, and Toyota for their trucks. Still, plenty of folks do opt to make the Titan their pickup truck of choice. And these are three of the most common real-world complaints that have been made. 

3. Leaky rear axle seals

Unfortunately, from 2004 until about 2013, the Nissan Titan suffered from overheating. Because of the lack of ventilation, the rear axle seals can leak. If the loss of fluid becomes too excessive, major damage can occur to the rear differential and axle bearings. And that certainly is not something that you want for your full-size Nissan truck. 

According to RepairPal, this problem typically pops up around 100,000 miles. And so far, over 140 owners have reported the issue. With that in mind, you should keep an eye out for any fluid loss. 

2. Premature fuel pump failure

Your truck’s fuel pump is what is responsible for delivering fuel from the tank to the engine. With a failing fuel pump, a number of issues can arise, and that can spell trouble for your Titan. One big issue that seems to come up is catalytic converter damage.

In modern vehicles, the catalytic converter is part of the exhaust system. It helps to control emissions. If there is an issue with your catalytic converter, it is still possible to drive your truck. But it is not really a viable thing to do in the long term. So, if you notice the fuel pump going out on your Nissan Titan, it could damage this important component. 

1. Engine and transmission issues due to corrosion

OK, so this is kind of a two-pronged issue. Corrosion can be a big issue that trucks face, especially because they do tend to be on the road for so long. Water can cause corrosion in the connector between the engine and transmission wiring harness.

If this happens, not only can your Nissan Titan struggle to start, you might face transmission shifting problems. There aren’t any reports on RepairPal of this happening after the 2010 model year, but if you own an older Titan, it might impact you. The average mileage when this happens is 115,147, so when your truck hits that milestone, be aware. 

Is Nissan discontinuing the Titan?

Unfortunately, it does look like Nissan has plans to kill off its full-size truck. It’s not exactly clear when the Titan will be discontinued, but because it isn’t that great of a seller, it does make sense that the brand is considering that move.

One does have to think, though; the new generation of Frontier has been pretty popular. Maybe, if Nissan made an investment in the Titan, it could see renewed interest from the public. The Titan is the only full-size truck that comes standard with a V8, and you get a host of safety tech. This is in a world where the Toyota Tundra doesn’t even offer a V8 engine as an option.
