Radiator failure leaking into tranny, causing a sound coming from transmission as if driving over a rumble strips when accelerating between 40-60mph, as well as sudden jerking when changing gears. SMOD residue (creamy pink fluid) present on radiator cap. This is a known issue that I was never made aware of during nor after purchase. Obviously this was not addressed prior to the sale by the Nissan Dealership. No warning signs were present prior to the issue appearing. Vehicle has not been inspected by the manufacturer yet as I am only now learning of this problem, however I have made arrangements. The issue is confirmed by third parties. Vehicle is available for further inspection upon request. The issue first appeared about 2 weeks ago but symptoms were milder and progressively became more noticeable. Sudden transmission failure on the highway could be catastrophic and is part of my daily driving routine.

Transmission failed, @ 133 thousand miles. Coolant made its way into the transmission.

At 130,000 miles we started to notice transmission issues such as slipping and at 40 mph, a vibration like you was running on the rubble strips on the highway. Took to the garage and they said it was due to bad tires. Paid over $500 for new tires, problem still occurred. Was told since no engine code, they had no clue what was going on. The slipping got so bad, clearing a intersection or pulling out into moving traffic became dangerous. Frustrated with dealer bs and other garage bs. I youtubed it. Saw a defective radiator video. Checked my antifreeze and transmission oil to find them both milky. My truck is 9 years old and the radiator failed. The safety of my family was at stake when the transmission failed to work as we waited for antifreeze to power our transmission and watched our engines overheat as it was now cooled with oil. 100% should have been a recall, 1000% should have been at least a warning to customers of the risk to our safety. I`ll never buy a Nissan again, or recommend other to do so. At 100,000, both rear leaf springs broke. Truck has never been used to haul heavy loads to cause this failure. On top of that, the steering radius really sucks. A three point tun in this truck is really a 21 point turn.

Vehicle won't shift right. Was on highway when it wouldn't go very fast or shift. Only 5 miles from home, I took it home and checked the radiator cap, it is full of pink frothy anti freeze and oil. (milkshake)

Faulty radiator causes coolant to leak into transmission fluid.

Radiator fluid leeks into transmission and ruins the transmission

Transmission has been slipping. Happens frequently when stopped at a red light, stop sign...when time to go car does not move. Complained to Nissan dealer in 2014 and they suggested changing the fluid...could not find any problems. Fluid was changed and I am still having problems. Will be taking it to another dealer this week. I understand Nissan has had major issues with coolant leaking into transmission as I had a 2005 Nissan Frontier and this is what happened to me. Nissan would not compensate me as my mileage was 100+K. when I treaded in my 2005 for a 2010 I was assured that Nissan had fixed the defect. Here we go again...I should have known better!

After driving a short distance to exit a parking lot and waiting for an opening in traffic on a busy four-lane road with a speed limit of 50 mph, I hit the gas to accelerate into an opening and nothing happened, no forward motion. And there have been subsequent incidents; one involved trying to cross a busy street from a stop sign. This is a definite safety issue; when the drive train is unresponsive in such circumstances, people could be injured or killed. Today, I took my vehicle to a Nissan dealer for an oil change and to have this anomaly checked out. They have informed me the radiator cracked, leaked coolant into the automatic transmission, and both must be replaced. This is being done at no cost to me, as there is a known issue with the radiator cracking for which Nissan has increased the warranty to 8 years or 80,000 miles. However, the warranty notification doesn't mention the transmission may be compromised, stating only, "in vehicles equipped with automatic transmissions, a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant." My vehicle is four years old and just hit 12,000 miles.

We have had the rear U joints replaced 3X on our truck and have rear axel fluid leak etc obviously the driveshaft is misaligned and eventually will fail. Also the transfer case and transfer case motor is failing. The first U joint incident happened IN6/01/11 at mileage 41,638. The transfer case issue began 10/26/12 at mileage 76,380.

The rear axle seals are leaking. There is a service bulletin at Nissan for this issue. So this is a known issue. Rear differential fluid is leaking on the rear brakes. This will cause rear brake failure. I think there has been numerous cases of this problem. Nissan best to my knowledge will only take care of this issue if the vehicle is under warranty.

Noticed E-brake no longer holding. Took to local shop. Told me need new E-brake pads and rear axle bearings, seals. Apparently bearing seals failed and gear oil saturated brake pads. Took to dealer to fix bearings and seals under warranty (though they charged me for the brake pad replacement that was a direct result). A little online search reveals the bearing problem common on Frontiers, a result of improper axle venting. Apparently there was a retrofit part that Nissan sold to address this that has since been pulled from the parts offering.

Transmission slips when placed in gear, does not engage right away.

I put my 2010 Nissan Frontier truck into four wheel low to back my camper into its parking area. The parking area is located at the top of a slight incline. After backing the camper into position I placed the truck into park and left it running while I secured the camper by placing chocks behind its wheels and putting a foundation for the jack. I removed the safety chains and the hitch lock from the camper and jacked it up. As the hitch came off the truck ball the truck began to roll down the hill freely. I was unable to catch it before it struck things in its path and finally came to rest hitting a tree. The truck was still in park but the indicator for the 4 wheel drive and vdc was off. The truck when put N reverse would not move. I turned it off for a few minutes and restarted it acted normal.

6-speed manual stick shift transmission; clutch failed prematurely at 20,160M, 13mos vehicle age; several months prior, intermittant burning smells of unk origin when backing vehicle that went away quickly may have been only symptom of impending premature clutch failure. Sole driver/owner is veteran stick shift driver since 1975, previous sole owner of a Ford Ranger stick that did not have clutch failure until 11 yrs of driving it and 85,000M, so driver error not a factor. Clutch failure in mid-traffic resulting in having to divert vehicle off main roads and slowly limp it to nearest Nissan dealership; clutch failure got progressively and dramatically worse in a span of just 10 minutes. Even though vehicle is covered under both a 36K/3yr bumper-to-bumper warranty and 6yr/75K extended gold preferred manufacturer warranty, Nissan refused to cover the premature clutch failure under warranty, claiming driver error. Mechanic for previous Ford Ranger is willing to testify to driver stick shift expertise. Driver was placed in harm's way by clutch failure; driver's expertise with a stick is the only reason vehicle was able to be driven in a limping fashion to nearest dealership.
