2009 Nissan Frontier King Cab SE 4dr King Cab 6.1 ft. SB (4.0L 6cyl 5A)
Buyer Beware! The Good the Bad, & The Ugly
 I will start this review off stating that the North Carolina Consumer Council urges people to stay away from this vehicle: http://www.carcomplaints.com/news/2016/dont-buy-nissan-pathfinder-frontier-xterra.shtmlIf you're looking to purchase a used Frontier it is imperative to look out for two costly failures. They start occurring around the 100k mark. I will list them from most to least expensive.1. Coolant leaks in the transmission fluid. Bring a ratchet with an extension and a 10mm socket to remove the bolt and check the transmission fluid. The dipstick isn't easy to find, so Google it and you'll see where to locate it. If the transmission fluid is pink, or has the look and consistency of Pepto Bismol, the transmission will fail, and the radiator will need to be replaced. Estimated cost to repair at Nissan dealership = $3500 - $60002. Listen for the timing chain tensioner failure.  After starting the engine pop open the hood and listen to area where the timing chain is near, also if you can have someone rev it up a few times to see if you hear the whine; if you hear a whining sound, similar to an remote controlled car moving, then timing chain tensioner has failed and the timing belt will eventually get too loose and destroy the engine. All of the timing chains and tensioners will need to be replaced. Estimated cost to repair at Nissan dealership = $1700 - $2000 if ignored and the timing chain fails you will need a rebuilt engine estimated cost ??? (thousands)The radiator/transmission issues can be avoided by rerouting the lines that run from the radiator to the transmission directly into the transmission cooler, but a better solution is to install an external transmission cooler bypassing the radiator altogether; this way coolant will never have a chance to enter the transmission even if the radiator fails, or leaks occur.If you've made it this far that means you still have interest in the vehicle so I'll continue with my review of actually owning the truck.The Good: Up until 100k the truck was sound mechanically. Had no major issues. The truck accelerates very nicely. The performance is great, and the ride is even more solid when you have a load. I have never towed with it, but the towing capacity is pretty good for a light truck. The A/C gets cold quickly, the heat sometimes acts up and doesn't want to heat until moving, but eventually that goes away. The bed size is great, I've hauled some pretty nice size loads in the thing and I've rarely had issues with not having enough space. I liked the look of this truck over the others in the class at the time. The king cab gives you enough room to store groceries, or have a small child in the back. I've had adults squeeze back there but I would not recommend it. The truck handles well, with the exception of the turning radius. The truck stops when you press on the brakes, and they will get spongy if you don't keep up on them, but even then it will stop abruptly. With that being said this truck is fun to drive and performs very well.The Bad: The Bridgestone trail rated tires that come with the truck are useless on wet pavement and makes the ride quality horrible. I replaced with Michelin tires, I can't recall the rating, but it changed the traction, handling, and ride quality dramatically! The turning radius isn't the greatest. I've wondered how heavy trucks can outturn my truck, at first I thought it was my driving skills, but after driving other trucks; I realized that it's the Frontier with a sad turning radius. You will have to get used to this and swing out on turns, and U-Turns in the thing are terrible at best. Good luck driving this truck, rear wheel drive, in the snow/ice without some kind of weight on the back of the bed. This probably holds true with most rear wheel vehicles, but I'm just pointing it out for people in snowy climates.The Ugly: I started noticing this weird whining sound, and rough start whenever I would crank up the car. The truck would rock when I started it up. I was due for a tune up, so after getting that done the rock went away a little, but the whine was still there. I started doing research and I saw that Nissan issued a service bulletin about the timing chain tensioner issues. Took it to the Nissan dealership the service tech said I need a new timing chain $1900. I did more research and found out that this has been an issue since the 2005 Frontiers and that I missed the boat on getting this fix done under warranty, at this point I was pissed because I was never aware of this issue until after the warrant before it happened! Went to another mechanic that fixed it for 10 hours labor & parts for $1700. Now I'm looking to bypass the radiator and get an external transmission cooler to prevent myself from possibly having to purchase a new transmission and radiator. Just know, Nissan is on the bottom of reliability and customer satisfaction rankings for a reason.
