Automatic Transmission Cooler problems of the 2007 Nissan Xterra

Purchased this vehicle July 2019 from owner. After 3 weeks transmission started acting weird while on vacation transmission seized due too coolant leaking from radiator cooler into transmission. Total repairs tow costs and rental car rental exceed $5000. 00. I understand there was a recall on this vehicle for transmission and cooling system related proplems. This vehicle only had approx. 100,000 miles on it when purchased. And onlu has approx. 128,000 on it. Now. Can I get any type of reimbursement for costs paid out of pocket????.

Transmission failure due to leak from radiator cooling system fluid intermixing with transmission fluid. Check engine light came on while driving, went to repair shop the code p0717 came up. Upon inspection by the repair shop it was determined that the transmission, radiator, and all hoses,etc. That interconnected the transmission and radiator had to be replaced. I live in California and the problem occured in arizona.

Radiator cracked and cooling got into my transmission. I bought the car used at a dealership in 2014. Which I think dealership should have warned me about the problem too. I was driving down the highway and overdrive started shuttering and so I had to put it into 4th gear to make it on down the highway. So then I looked it up online what I could do what causes it to shutter and then I seen the notifications about the coolant in the transmission so I checked the radiator and sure enough there was white foam or sticky stuff in there. So now it's going to cost about $3,000 for a transmission and to have it put in and I still owe $4,000 on the vehicle which is now a yard ornament until I save the money up to pay for the transmission.

Our 2007 Xterra at 87,000 miles left my wife and 2 kids stranded on the road with a destroyed transmission due to a defect in the radiator cooling lines that support cooling the transmission. The coolant mixed with the transmission fluid and the resulting pressure caused the radiator pressure cap to blow when the engine overheated. This strawberry milkshake looking fluid leaked all over the ground and was difficult to clean-up this is a known Nissan defect issue and should be a recall before someone get hurt or further environmental pollution results.

Transmission cooler ruptured, ruined the cooling system. Appears to have damaged the transmission.

Contamination of the transmission with anti freeze due to leak in cooling system, resulting in transmission failure.

This week my sons 2007 Nissan Xterra would not start and we had it towed to a Nissan dealership near his college in scranton PA. Yesterday we were informed that the transmission and radiator need to be replaced, at a cost of around $5000! this is shocking because my son insists that he noticed nothing amiss with the operation of his truck until it he was unable to start it. After spending 10 minutes on the internet, I learned about the Nissan transmission class action lawsuit. We have been religious in terms of scheduled maintenance, and overall care of the vehicle. We were not aware of the cooling/transmissions problems plaguing Nissan trucks. In addition, I have had the vehicle serviced at two separate Nissan dealerships, one in new york and another now in PA. It is disgraceful that neither Nissan dealership mentioned anything! this morning I contacted Nissan corporate and was told that since the vehicle is over 100,000, there is nothing they can do for us. I do not have $5000 and do not know what to do with my sons Nissan. As others have mentioned in postings, there likely many others with vehicles over the 100,000 marker, now just experiencing the negative effects of the defective manufacturing by Nissan. There should be a second class action suit filed against Nissan!!!.

First noticed a stuttering when driving and a clunking sound when moving the shifter from park to reverse to drive in February. Also experienced no heat and over heating in March. Upon repair of thermostat, draining the radiator showed an accumulation of thick grey gunk in the coolant. Thermostat seal itself was melted. Had dealer evaluate clunking sound and they diagnosed it as intermix (the problem identified by the coolant) a manufacturing defect in the radiator/transmission cooling components that allows the coolant to contaminate the transmission fluid causing transmission damage. As a result of class action lawsuit, dealership explained that mileage was over the Nissan warranty limit of 100,000 even though the problem did not manifest until almost 120,000 miles. Recommended fix was in stages - 1) replace radiator and transmission flush $1200++ 2) if problem is not solved, replace transmission $4000++ have talked with Nissan corporate to no avail. Case # is 14308171.

My 2007 Nissan Xterra started having both transmission and cooling system issues back in September 2014. After a few trips to our mechanic it was discovered that the vehicle had a cracked radiator and was allowing both coolant into the transmission and transmission fluid into the cooling the system. Apparently this is a well known issue and there was a class action lawsuit against Nissan, however the terms of the settlement only cover vehicles under 100k miles. By the time we found out the vehicle had just passed 100k (106k) and now Nissan refused to cover it! I'm now looking at a $5k - $6k repair bill and Nissan refused to budge.

I have had the same problem described in your current investigation of these models. An atf line embedded in the radiator cracked, and atf fluid was allowed into the coolant, and coolant was forced into the atf. The card started slipping in gear, then it started shuddering under acceleration, then it started refusing to go into gear. I got it to a transmission shop, and when they opened it up, the guts of the transmission were rusted, and the clutches had DE-laminated. The cooling system was nearly plugged up with oily transmission residue. The transmission had to be completely rebuilt, and the radiator and all associated hoses had to be replaced. All in all, a $5500 fix for a problem that shouldn't have happened.

On Friday, August 2, 2013, approximately 5:40pm, the car started to have difficulty shifting (automatic), speed became erratic, slowed rapidly. I was on a service road next to a freeway during rush hour traffic in a busy area of scottsdale. I was near pinnacle Nissan and decided to drive there. I had a couple very busy intersections to go through to drive the 1 mi to pinnacle. The car would not accelerate more than 10 miles an hour and was not shifting out of low gear. I was very concerned I would stall or the car would cease driving in these intersections. Pinnacle Nissan service diagnosed the issue (8/3/13) as a cracked radiator cooling tube that caused coolant to mix with transmission fluid ruining components in the transmission. A complete new transmission and radiator is required to fix this now. This issue is not related to abusive driving, I do very little off road and no towing, and is not a lack of or improper maintenance. This is a know design flaw by Nissan. It appears there is a high number of Nissan problem SUV's, 2005 to 2010, that experience this same problem after roughly 80,000 miles. Based on my experience, this is a potentially dangerous safety issue especially if someone would be driving at higher speeds on a busy freeway.

Transmission downshifted on its own at 45 on a mild downgrade. Did it again later changing from one four lane highway to another, this time around 45-50 mph. Took the truck to local Nissan dealer for diagnosis as I took out an extended warranty with olympicare. The service adjuster was aware that '05-'09, even '10 models have a defect that allows radiator fluid to mix with transmission fluid, creating degradation of transmission and cooling system. After-market warranty is trying to dis-allow claim, citing Nissan's knowledge of this design flaw.

I particpated in the Nissan campaign to replace a radiator and transmission, due to a defective assembly that caused tran failure. Dealership replaced the two main parts under the campaign. I received my vehicle, and only had it for 1 1/2 days before another issue related to the radiator / cooling system was experienced. I was yet again, on the highway heading to a job and overheated, thus disabling my vehicle. I stayed the interstate for 3 hours waiting on roadside assistance to tow me back to the dealership. I'm having an issue with Nissan not willing to cover what's clearly their problem to begin with. It's not the consumer's problem that they installed faulty components in their cars and trucks, that caused the major malfunctions. If I were a consumer (which I am); I would feel that they are not owning up to the full liability caused by their neglegence in putting inferior parts in their vehicles that caused the malfunction in the first place. I'm not only upset at their response; let's not overlook the fact that on the two days my truck failed (first time when the tranny blew out on the highway, and the second time when I was on the highway again; and overheated); I was heading to job obligations I had for private clients of mine. I lost 1,375. 65 on day one for missing my appt. On the first incident, and an additional 868. 04 on the next incident. My truck's issue is that there needs to be a system flush of the radiator and the thermostat needs replacement. . . Both are direct cause of the incident with their crappy radiator assembly they put in the vehicle in the first place. I don't have the extra money to do the maintenance, and I've lost money in the ordeal as well. I think it be "best practice" and good customer care; that nna cover the cost of the flush and the thermostat, caused from the mixture contamination of coolant and tran fluid.
