Transmission Fluid Leaking problems of the 2005 Nissan Frontier

Lost power could not move truck on city street. Dealership told me it was the transmission coolant was leaking into the transmission fluid wariness the gears and the transmission had to be replaced. They told me there was a recall but I never received a notice they said the recall has expired and I have to pay for the repair.

(aw no dealer info) tl the contact owns a 2005 Nissan Frontier. While driving various speeds and shifting gears, the vehicle hesitated and jerked. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the radiator water and coolant fluid leaked into the transmission. The transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 49,000.

The contact owns a 2005 Nissan Frontier. While driving approximately 40 mph, the gear shifted abruptly and the vehicle jerked and vibrated. The contact noticed an odor of burning transmission fluid. There were no warning indicators illuminated. The vehicle was taken to a dealer where it was diagnosed that the transmission fluid leaked into the transmission. The dealer also diagnosed that the transmission fluid was corrosive and destroyed the components of the transmission. The dealer recommended that the transmission be replaced. The manufacturer was not made aware of the failure. The failure mileage was 82,500.

Transmission failure due to radiator leaking coolant into transmission fluid. I replaced the radiator a year prior to prevent this problem from happening at the strong recommendation of the dealerships service department and still the problem occurred.

Radiator leaking fluid into transmission . Notices slight shutter at high speed, approximately 65 mph, in the transmission. Vehicle was checked by dealer at 89,000 miles without any issue at that time . Dealer would not replace radiator due to no problem at that time. Vehicle is at 112000 and now radiator fails. Nissan would not cover due to out of extended warranty. Faulty designed system and potential safety hazard in my opinion. Vehicle at my independent mechanic for new radiator and transmission flush out to see if it will fix problem. Major expense for poor design passed onto customer. I will not spend any more money with Nissan.

Radiator leaked fluid into the transmission. . . Broke down on highway at 103,000 miles. . . . Well known and documented problem with this year and model.

In 2013 I received a notice of class action about a Nissan vehicles related to possible radiator fluid leak into the transmission due a defect that permits cross-contamination of engine coolant and transmission fluid. It did not include vehicles before it happens. In 2013, I went to a authorized Nissan dealer to check if my radiator can be affected but they told me that in that moment the radiator was working well without given me the option of replacing it to prevent damages. At the time I was under the warranty limits, less than 10 years and less than 100,000 miles. Now in February 13, 2016 my vehicle began to have problems to move , had a harsh shift , it slowed down and did not drive at times. I clearly saw a transmission problem. I called united Nissan service for a diagnose . They check my vehicle and told me that my radiator leaked fluid into the transmission due the radiator defect. I couldn't understand why this class action did not include vehicles that will face this damage in a future . It did not include prevention of damages. Nissan did not released a recall for the faulty radiator. I know I am now outside the warranty limits, but at the time when I visited Nissan service to prevent this no one provided my help or information that would help in prevent such damage. The price for a new transmission is 6,000 dlls. The total cost of repair all goes up 9,000 dlls. Also I received a rude customer service by the service agents of Nissan service . Now I have to cover these costs by myself. My son was driven the vehicle when this happen. The good thing is that the failure occurred while he was driven on the freeway making it so dangerous. What will happen with people like us? the legal case was closed in 2012 but Nissan still having vehicles suffering this this damage . This is a negligence that pass the financial burden to consumers.

Transmission began to shudder at speeds 40-50 mph a few weeks ago, feels like going over shallow rumble strips. Did research online and found that the issue is coolant leaking into the transmission fluid. This has been a major issue with all 2005 Nissan Frontiers. My truck has 103,xxx miles. Outside the warranty now. Never new of this warranty and now I’m stuck paying thousands of dollars out of pocket for new transmission and radiator.

Vehicle made a noise what sounded like driving over a rumble strip. It then failed to accelerate and I was forced into the breakdown lane on the highway. I had vehicle towed to shop and was informed of the radiator and transmission issue with these vehicles. Radiator fluid leaked into the transmission and now its junk. It will now cost me $3400 to replace the transmission and radiator. I can't believe there isn't a recall out for this issue. This is a complete disregard for consumer protection.

Vehicle shudders bad in 5th gear clunking in and out of gear, and unable to maintain speed on highway. Hard up shifts from gears 1 to 2 and 2 to 3. Hard down shift clunk from gear 2 to 1. Coolant leaked into transmission fluid causing catastrophic failure of transmission and new radiator needed as well.

I was driving on the highway and my truck shutters like going over shallow rumble strips for about 3 weeks. I realized it was my transmission and searched on transmission issues with my truck and found the big one (coolant leaking into the transmission fluid). I immediately flushed the coolant and the transmission fluid, performed the at cooler bypass operation and refilled. I'm now saying my prayers, taking my vitamins, and exercising hoping for the best.

The radiator cracked and leaked coolant into the transmission, mixing with the transmission fluid creating a toxic fluid that irreversibly damaged everything around it. The vehicle was being driven when first noticed. I had the radiator replaced and the transmission flushed at my local Nissan dealership. I could not afford to replace the transmission so flushing it was my only option. It lasted for a few years but now it needs to be replaced. This is a defect that has affected thousands of customers.

Radiator leak into the transmission fluid, causes transmission to fail and requires a rebuild. Expensive $3000 repair. Current litigation and court case does no good to most of the customers experiencing this problem. No warning from Nissan that the radiator is flawed.

The transmission started jerking very bad when it hit 1700 rpm range while driving, so I slowed down. . . Scared. I went and had it checked only to find out it is very common with this truck - fluid in transmission caused from the trans fluid running through the radiator and the heat exchange leaks water into the trans fluid. This is a well documented problem I learned. The repair is not covered by Nissan and is a 5000 dollar repair at Nissan dealership, a total transmission and radiator replacement is needed.

Sudden loss of power/stalling. Check engine light came on as well as anti-slip light. Took vehicle same day to Nissan dealership. Truck actually stalled on the way to the dealership however I was able to get it started again. Diagnosed the problem as a bad cam shaft sensor. Sensor was replaced. They also mentioned that transmission fluid was contaminated with engine coolant. Suggested repair was to replace the radiator and the transmission-$4800. I chose to just replace the cam sensor. Three days later, 8/9, lost power at highway speed. Radiator and hoses leaked and had to be towed to dealership. Again dealership suggested replacing the radiator as well as the transmission. Replaced radiator and hoses, flushed transmission twice. I plan to dispose the truck. There were no warning signs prior to these two incidents. My opinion is that this is definitely a manufacturing/engineering defect.

I was driving the Nissan Frontier about 50 mph when the rpm shot up then dropped and the transmission quit causing the vehicle to stop. I had to cross two lanes of traffic to avoid a major accident. I managed to get the truck to the dealer and was told it was a problem with the transmission leaking fluid into the radiator causing the transmission to fail with out any warning. I was told the fix would cost me around 5,500. 00 dollars. Nissan is aware of this problem and really should correct it before some one is killed by this obvious major malfunction in the design of there product.

Tl - the contact owns a 2005 Nissan Frontier. The contact stated that while driving 35 mph, the vehicle stalled and the slip warning lamp illuminated. The contact mentioned that he was able to restart the vehicle immediately after the failure. The vehicle was taken to an independent mechanic. The technician diagnosed that the radiator coolant hose was leaking and the cam shaft position sensor was defective. As a result, both components were replaced however, the remedy failed to repair the problem. The vehicle was taken back to the independent mechanic, who stated that there was transmission fluid found in the radiator and due to the failure, the transmission and radiator needed to be replaced. The manufacturer was made aware of the failure and stated that they would cover a portion of the repair cost. The vehicle was not repaired. The failure and current mileage was 74,494. Kmj.

I was in the turning lane, needing to cross the intersection, light turned got a flashing yellow light , pressed gas and heard a big bang, then the truck was just stopped in the middle of the lanes with cars approaching. Luckily the approaching drivers were aware of my presence and no vehicles hit us. When it was ok to move the truck, myself and 2 other drivers helped push it clear. After examining the vehicle I noticed mustard yellow substance in the radiator overfill and one of the guys that help push looked at the transmission fluid to find a strawberry milkshake color fluid in there. After being examined by a mechanic it was determined the radiator was leaking fluid into the transmission. The Nissan dealer said the truck doesn't fall into any warranty, so it will cost me 7000 to fix. So needless to say this situation could have been extremely dangerous to me, my family and to the other drivers if they hadn't been paying attention. It's sad to say that Nissan is letting this happen to its drivers, over a 100 dollar radiator costing us thousands of dollars to fix and how long before someone is killed.

Coolant leaked into transmission fluid and destroyed transmission.

Suddenly my truck appeared to have no power; could not accelerate up to traffic speed or effectively get across an intersection. It was scary and dangerous as this could have easily caused an accident. The "service engine soon" light came on and I promptly took my 2005 Nissan Frontier nismo v6 to my local Nissan dealer for service. I had just had the full 90k mile service with radiator flush and no issues where reported to me. So I was shocked when they told me that it needed to have both the radiator and transmission replaced due to "fluids mixing". Antifreeze and water from the radiator had leaked into the transmission and destroyed it. And I was further shocked and angry that it would cost me $3k even after Nissan's "extended warranty". (I don't have this kind of money lying around to dump into my 7+ year old truck, that I had bought new in '05. ) this is a catastrophic defect in the design - known by the manufacturer and should be made right by the manufacturer. I've found that there are hundreds of complaints about this same issue across the internet for other 2005-2010 Frontiers, pathfinders and xterras. Nissan needs to do their consumers right, or risk loosing loyalty. Up until now, I've been really happy with my truck, my service dealer and Nissan, but now I'll be looking at other brands that back their products and consumers better.

My 2005 Nissan Frontier began shifting hard noticeably. I took it to a trusted mechanic to evaluate the cause and learned that there is contamination in the transmission fluid. Coolant from the radiator has leaked into the transmission body, resulting in contamination and corrosion. At this time the transmission still functions, but will not continue to do so for long. This issue requires the replacement of both the radiator and the transmission with an estimated cost of $3,800.

The contact owns a 2005 Nissan Frontier. The contact stated that while driving various speeds, the transmission slipped gears. The vehicle was taken to a private mechanic where it was determined that transmission fluid was leaking. The vehicle was repaired but the failure recurred. The manufacturer was not contacted about the failure. The failure mileage was 110,000.

Stopped on hill behind another vehicle, they took off, I tried to pull up to stop sign but had no forward movement. Luckily no one was behind me so I backed down to a driveway to get out of the road. I had reverse at this time. After trying to figure out what happened, I put truck into gear and drove the five miles to work. Service engine soon light came on. Left work and had no problems until my driveway, steep incline and again no forward movement. No reverse this time. Had it towed to transmission shop and they have diagnosed that the radiator fluid was leaking into the transmission. Surprise! I did not receive a letter from Nissan last year. They should recall and pay for all the charges. They know there is a problem and don't want to own up to their failure to provide a safe vehicle. Hope the NHTSA looks into the problems with the Nissan vehicles. I was happy I wasn't on an inter-state. No indication of a problem until I had no forward movement! very dangerous for everyone on the road!.

Tl- the contact owns a 2005 Nissan Frontier. The contact stated while driving 60 mph the vehicle stalled. The vehicle was towed to a dealer for diagnosis and the contact was informed that radiator fluid had leaked into the transmission. She was also informed that the radiator and the transmission would need to be replaced. The manufacturer was notified and advised her to contact NHTSA but offered no other assistance. The vehicle had not been repaired. The failure and current mileage was 123,000. Dt.

Brought vehicle in to mechanic because of rough sound happening occasionally. It turns out it was the transmission, and that radiator fluid leaked into transmission which has caused transmission issues. Cost to repair will be approximately $4,000. This should not happen to a vehicle with 66,000 miles.

Nissan has a known problem with the radiator and transmission. The date listed is merely the date we discovered the issue. Before Jan 31, 2012 we knew nothing about this problem. It is a safety issue. You don't know if this has happened to your truck until it overheats and you find out the fluids have mixed. Replace the radiator. Flush the fluids (3 or more times, since the fluid is now like purple soft serve ice cream). Then the real troubles begin. . It slips out of gear while driving at 70 mph and the only option is to pull over, turn the truck off, remove the key, then restart the truck and hope it works. This is really dangerous on the highway at the higher speeds but also unsafe on the side roads or in stop and go traffic. I take my kids to school 3. 6 miles each way. I have to stop and restart the truck at least 3 times during the round trip. Speed doesn't matter. You stop at a red light and have know idea if it is going to go when you push the gas or not. Pulling out into traffic can be very dangerous since you have to go and you find out you can't. There have been several "warranty extentions" issued by Nissan on our truck that we were not aware of until after making the repairs on our own dime. There is a "warrany extention" for this issue due to a class action lawsuit but it does nothing for a lot of the owners since many are over the "extention mileage". I try to never drive the truck on busy roads without shoulders or turn lanes, I fear red lights and traffic but stop signs are the worst. . . I never know if the transmission is going to work or not. All because a known faulty radiator cracked and leaked fluid into the transmission. But, I'm over the extended mileage so I'm expected to pay over $5k to fix a known issue.

Nissan has not stood behind their product once so ever. Radiator fluid leaked into the transmission causing it to go out. Nissan knew about the problem and did not send out a recall for the problem and never did till this day. Although they choose to on other problems. Its a saftey issue as well and Nissan does not seem to care at all. They went on selling cars like normal and choose to leave there past consumers in the dust. Not working with or caring about us. I work hard for this truck and Nissan does not want to help and wont help one bit. Even though its completely due to a manufacturer flaw by Nissan as a company and they know it! please help.

Had to replace radiator and transmission. Fluids leaked between the two.
