Engine Cooling System problems of the 2005 Nissan Xterra

Transmission failed due to a a known defect in the Nissan cooling system for 2005 Xterra's - this defect allows anti freeze to leak into transmission and cause failure.

Faulty radiator leaked antifreeze into transmission which rendered the transmission useless.

2005 Nissan Xterra- routine maintenance found radiator full of transmission fluid. Transmission approx one quart low. Defective radiator known by Nissan for some time now. Only extended warrantee to 80,000 milesfrom what I learned. My car has 90,000 miles. Received no notice or warning prior. Numerous owners complained. Some required transmission change costing thousands of dollars. In 2010 I bought another Nissan, frontier, it has the same radiator apparently. If I would have known earlier, I would have never purchased another Nissan. Why is there no recall on these Nissans, 2005 and sebsequent? it is costing taxpayers millions out of pocket. I was lucky, I was spared a transmission change. I had the transmission fliud cooler in the radiator disabled and I installed a separate transmission cooler in stead. It did cost me a loss of my road trip vacation though.

My 2005 Nissan Xterra suddenly developed a lack of acceleration nearly causing an accident at a stop sign. When taken to my mechanic I was told that the trouble code indicated the tcm and or the front brake solenoid, both of which are in the transmission and they would cost at least $2000 to fix. The dealer would not talk to me or return my calls after letting me know that a fix would cost @$5000+ I cannot afford to replace this and after finding that it happens with nearly all 05 Xterras I will not.

Radiator failed and leaked into transmission and problems with fuel system. Truck shook and would not speed up going on to highway. Family almost got hit by truck.

The contact owns a 2005 Nissan Xterra. The contact stated was driving 30 mph when the transmission slipped. The vehicle was taken to the dealer where the contact was advised that the transmission fluid abnormally mixed with the radiator coolant. The radiator initially malfunctioned and caused the failure and the dealer advised replacing the transmission. The contact called the manufacturer yet the manufacturer did not offer any further assistance. The vehicle was not repaired. The failure mileage was 84,000.

My 2005 Nissan Xterra se with 82k miles had the radiator fail, leaking coolant into the transmission. This is a common problem with Nissan suvs and trucks for at least 2005-2007 model years. Nissan voluntarily extended their warranty to cover this type of issue to 80k miles, but it seems typical form the many online message boards addressing this issue that the problem arises after 80k miles. Nissan refuses to cover any of the costs of repair.

Radiator failure causing fluid to drain into transmission. This caused damage to the transmission and torque converter. I was left stranded without warning in the middle of an intersection. The transmission was rebuilt, the torque converter was replaced, an external transmission was installed. Cost of repair: $2,852.

The car began to have a shaking feeling like you were driving over a rumble strip about 4 months ago. We took the car to dealer and they determined we had the issue that Nissan had reported may happen where the radiator fails and coolant gets into the transmission. The dealer said the entire cooling system and transmission would have to be replaced and the cost would be $6500. 00. Nissan had sent us a letter last year stating they had extended the warranty on the radiator and all of its corresponding parts to 80,000 miles/96 months. Our vehicle has 94,000 miles on it. I called Nissan and they said they would do nothing. We are currently fixing part of the problem by fixing the radiator and flushing the transmission. When we have more funding we will have the transmission rebuilt because we cannot afford to purchase the new transmission.

The contact owns a 2005 Nissan Xterra. The contact received notification of NHTSA campaign id number: 10v517000 (engine and engine cooling) and the vehicle was taken to the dealer for repairs. After leaving the dealer, the driver noticed that all the interior lights were flashing on and off abnormally as the vehicle stalled. The vehicle would not restart and was towed back to the dealer. The dealer then advised that they repaired the recalled component only and that they were not able to assist in any other way. The vehicle was not further repaired. The failure mileage was approximately 76,000.

I just recently started experiencing a 'shudder' under mild acceleration between 40-60 mph with my 05xterra, v6 4x4 (~120k miles). Feels like my rear wheels are going over a rumble strip and only lasts a few brief moments. Took my Xterra back to dealer and they indicated possibility of transmission cooler leak allowing antifreeze to enter torque converter and transmission causing slippage; although they checked my fluids and no cross contamination was evident. They recommended replacing torque converter, transmission and radiator. . . To the tune of ~$5000. . . There's got to be better answer. . . And accountability on their part. . . I searched on line and found that I'm not alone with this issue. . . A number of folks have experienced the same issue. . . Nissan has even acknowledged a problem and has extended their warranty on the radiator, but not the torque converter, but my milage exceeds the extended period; if they know of the issue, why isn't there a re-call. . . If the torque converter fails while driving, it will most certainly cause an accident. . . Problem is getting worse and more frequent. . . There needs to be action by Nissan to correct this condition before someone is seriously injured due to a known problem. . .

My 2005 Xterra with 82k miles started vibrating badly when accelerating over 50mph. It felt like I was driving over rumble strips. I called Nissan assist on 12/29/2010 and was told my radiator had failed, leaked into the transmission and totally destroyed it. My only option was a $4600 replacement of the radiator and transmission. The Nissan assist guy then told me that Nissan knew about the problem, but instead of issuing a recall, they simply extended the warranty from 60k to 72k miles (this was an error on his part, because the extension was actually to 80k miles). Regardless, it didn't apply to me because I was at 82k miles. Nissan is trying to ease the pain with extending the warranty however, they make no attempt to contact you about it. You either need to find it yourself or your screwed.

Beginning summer 2010 2005 Nissan Xterra (purchased new in 2005) began making rumbling noise (as if going over rumble strips) while driving. Incident occurred frequently at differing speeds for the next several months. No other problems were evident at that time. In November 2010 while driving on freeway vehicle began overheating, blowing hot air through air conditioner, and registering hot on gauge. Vehicle was immediately taken to local mechanic who was unable to determine problem. The next day vehicle was taken to dealership where car was purchased and told that the transmission needed to be replaced due to radiator fluid leak. After research and finding that this is a common occurrence the owner decided not to have the vehicle fixed at her expense and is not driving the vehicle until an agreement is made with Nissan. While there were no injuries or accidents in this incidence research shows that there have been numerous reports of transmission failures in traffic either causing or almost causing accidents. Nissan's failure to alert 05 Xterra owners of this problem that they are well aware of is negligence and risks health and safety. Further, it can be found that the problem cannot be fixed by simply replacing the original parts as the parts and design were defective to begin with. Research has shown that after being "fixed" by the dealership the problem has occurred again.

In September, 2010 I was driving my 2005 Nissan Xterra at 55 mph on a two lane highway when it the temperature spiked overheating the engine after pulling over and checking it I discovered I had transmission fluid in the radiator. Come to find out there is a known defect on 2005 thru 2010 Nissan Xterra's, pathfinders, and frontier's in which the radiators internally leak water into the automatic transmissions and causes the violent shaking at high speeds. Nissan is aware of the issue and has only chosen to extend the warrantee on the radiators and not recall the vehicles. In fact the letter sent to the consumers doesn't even reference the transmission (in which it destroys). While my family and I were not hurt, it was a close call and could have easily been worse at the speed I was going and the effect the failure has on the vehicle. The vehicle was towed to a garage and the radiator replaced and transimision flushed. While servicing my vehicle the mechanic discovered that the engine head had cracked. I incurred over 2,400 dollars in repairs. . . Using a used replacement engine. Nissan corporation after 9 weeks of waiting has informed me that they have opted not to assist in the repair of the vehicle nor provide reimbursment. On June 23, 2011, my transmission began to fail.

Problem as described by Nissan service tech: Xterra was towed to us with the concern "my Xterra is slipping, will not go backwards, will not drive in drive, only drive in 3rd, hooked up to computer and came up p1716". We confirmed the car would not move in reverse, as it was towed in and parked so that backing up was the only option. The code p1716 is related to the transmission turbine circuit not functioning properly. Upon further diagnosis, we removed the radiator cap to find the radiator filled with the milky combination of coolant and transmission fluid. The radiator is a sub-level radiator, where the top portion is for coolant and the bottom portion is for cooling the transmission fluid. The radiator cracked internally causing the fluids to mix. The transmission and radiator need to be replaced to rectify the problems. New transmission is $3215. 71 with the estimated arrival date of Tuesday, September 21. The new radiator is $538, currently in stock. The labor estimate is $1442. 70. The estimated completion of work is Wednesday, September 22, with estimated total bill coming to $5560. 16 tax included.

Car overheating, wouldn't run on highway, jerking, couldn't catch speed, radiator blew due to coolant problem which went into transmission needing new transmission. Holding up traffic, had to keep my hazards on. Extremely dangerous driving conditions. Radiator reimbursed by Nissan but wouldn't pay for transmission despite clear documentation that it was due to a recall. Had to pull over several times on highway to get out of harms way.

Radiator cooling system for transmission fluid causes malfunction of transmission causing unpredictable shifting and acceleration / deceleration Nissan dealership charging customers over 900 dollars for repairs. . . . . . Knowingly this engineered defect exists with most 2005 Nissan Xterra vehicles.

2005 Nissan Xterra with 69000 miles began shuttering every now and again when driving around town. It started getting progressively worse during the next few weeks. Thought it might have been the tire balance and had it checked. Balanced the tires, the shuttering was still there and began to get worse when driving at higher speeds I. E. 60mph. The rear end would shutter very hard to the point where we couldn't drive it any longer. Taking it to the shop revealed that the transmission had radiator fluid in it which was caused by cracked radiator lines leaking into the transmission. The fluid was into all the transmission gears. Come to find out that this is a common problem with Nissans and the only way to get around this problem is to place an external cooler to the transmission. Since the 5yr/60k power train warranty ran out, Nissan has no interest in assisting a well known problem of theirs. There complaint dept takes the info and places it into a database. Well the damage has already been done to the transmission and had to be replaced and an external cooler was installed which we had to go out of pocket on ($4100. 00).

Faulty radiator leads to transmission failure Nissan has know of this problem and done nothing about it cost of repair 5000 to 6000 many 2005 Nissan Xterra and pathfinders owners I know have had this problem please help!.

My 2005 Nissan Xterra had just under 100,000 miles on it. The transmission began to slip and there would be no power. I had it towed to Nissan and the radiator had leaked coolant into the transmission, destroying the transmission for about a 5,000 $ repair. Nissan offered no explanation other than "it happens", and after further research, found that I'm not the only case of this happening. Luckily for me, I was on a secluded state road when my transmission first slipped. Had I been on a freeway, I would have lost all power in a busy and unsafe location. . Read more...

I have a 2005 Nissan Xterra. The transmission had vibration intermittently. Transmission finally went out due to a faulty radiator. This vehicle is equipped with two coolers one air and one water cooled. I have read of many complaints for this. Nissan knows of the problem and should recall it. I bought this vehicle used from pat peck Nissan with a warranty. At 6mos I received a letter that the warranty was not valid on this vehicle and they reimbursed the cost of the warranty. I feel that they knew this was a problem.

1. Vibrations coming from rear of car at 35 mph. Vibration get worst when accelerating to 40 mph, shifts hard,rpm's increase then decrease(jumps all over the place). Occurs all the time. Faulty lines between coolant system and transmission. Coolant mixed with tranny fluid. Replaced, radiator,flushed engine, flushed tranny 2 times. Installed external transmission cooler and bypassed radiator, so this wont happen again, my have to replace transmission in future because of the damage done to it by the coolant mixing with tranny fluid. Out of pocket expense $1463. 12 parts and labor at a local Nissan dealer. I was told that this is a common problem with Nissan 4x4 vehicles. This should be a recall. And if my transmission goes I feel that Nissan should replace it free of charge.

2005 thru 2007 nissa Xterras and pathfinders made in these model years have a defective radiator. The transmission line corrodes and coolant leaks into the transmission line and contaminates the transmission. Repairs have to made to the radiator, transmission and all associated lines.

Internal radiator failure that led to a transmission failure in the middle of the highway. I had the radiator replaced at a cost of $1,300. 00 by the Nissan dealer where they assured me that the transmission was fine. A month later I paid $5,000. 00 to aamco to have the entire transmission rebuilt. This has happened to countless 2005 pathfinders and Xterras. Nissan will not provide financial assistance or make a recall. Nissan needs to be held responsible!.
