Automatic Transmission Cooler Problems of Nissan Xterra - part 2

Transmission locked in one gear which caused dangerous circumstances on well traveled roads. Subsequently, it operated normally, but the problem recurred. The occurrences were intermittent, and if occurred on a highway in heavy traffic could have resulted in an accident and injuries. Nissan has admitted there is a problem/defect by extending the warranty to 80,000 miles. However, this defect affects vehicles beyond 80,000 and is a significant safety concern. I understand the defect has to do with a cooling system in the transmission which is prone to cracking resulting in the mixing of radiator fluid and transmission fluid, ultimately rendering the transmission inoperable.

See all problems of the 2005 Nissan Xterra 🔎.

Break in transmission cooling coil inside radiator caused coolant to flow into automatic transmission. Transmission slippage at highway speeds caused vehicle to slow. Loss of coolant in radiator caused engine overheating. Result: vehicle undrivable at highway speeds, no acceleration due to slippage, costly replacement of radiator and transmission.

Transmission cooler leaked into radiator, fouled cooling system with transmission fluid, also fouled transmission with coolant. This caused vibration in the transmission, loss of acceleration, check engine light was activated for a clutch solenoid switch, and unknown possible damage to the transmission.

Nissan's 2005 Xterra has a major flaw in its cooling system and transmission. Apparently the coolant in the radiator leaks into the transmission causing the transmission to fail. This is very expensive as the radiator and the transmission have to be replaced. Flushing the system is not enough. This should have been recalled and repaired by Nissan before the problem became costly. Apparently Nissan has known about this for some time. This is disgraceful.

I have a 2005 Nissan Xterra which over the years my engine light would come on for all periods of time and then go off. The first time it came on I ran to the dealership because I could not afford to be broke down. No diagnosis was found (phantom light - $300 to tell no there was no problem) so after that I did not run to the dealer everything the light come one which was most of the time. Starting in January 2012 my 2005 Xterra would seem to have a difficult time changing over at certain speeds especially 40-45 and 55-60 mph. I mainly drive highway so I knew this was not normal for my car. Since the car was still running and I had a state inspection coming up in March-April 2012 I wanted to wait because I cannot be without a car. The engine light remained on from January until April when I went to the dealership. Finally in early April 2012 I realized that the heats was not working. At the April 10, 2012 inspection the dealership told me I needed a new radiator ($999. 45). They told me the radiator leaked into the transmissions but they were able to fix the problem. The car seemed to work fine after the repair, no difficultly changing over at certain speeds until October 18, 012 when I left work and the car would not start. Aaa came and tried to jump it to no avail. Towed to local mechanic (not going back to dealership again) and found out about the transmission cooling problem ($1,950. 98) and two weeks without a car and $100 towing bill. Now I get a letter from about lawsuit with Nissan but my vehile’s diagnosis occurred 1,985 miles after the allotted mileage (100,000). So, I am out $2950. 45 plus the cost of towing and rent a cars with the vehiile that I am never going to be able to trade in because no dealer would purchase it from me knowing the problems with 2005 Nissan Xterra. I will never buy Nissan again.

The automatic transmission cooling line that runs through the radiator failed and allowed engine coolant to mix with the transmission fluid, destroying the transmission. The estimated cost to repair was $6800. 00, greatly exceeding the value of the vehicle. Nissan declined to offer any assistance despite the wide spread knowledge that this is a design flaw and not a normal "wear and tear" failure.

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.

Defective transmission cooling design causing 2005 Nissan Xterra leaking coolant into transmission resulting in transmission and radiator failure. Nissan has not corrected the design problem for consumers resulting in putting consumers risk of harms way and extreme costs to repair.

My 2006 Nissan x-terra transmission and radiator failed radiator cooling lines for transmission failed and leaked into transmission causing complete failure of transmission. $4,000 to repair.

The cooling system is contaminated w/oily substance, transmission fluid. Trans. Is making loud noises, jumps out of gear @ hwy speeds, drive train making a 'rumbly' grinding sound, car dangerously pulls down very quickly to much lower speed when pressure released from accelerator.

Driving of vehicle has resulted in the failure of the automatic transmission. There appears to be a design flaw in the cooling system to leak onto the transmission causing failure. The only option is replacement of the transmission.

2005 Nissan Xterra- transmission failure due to leakage of radiator fluid from transmission cooling line infiltrating into transmission and causing it to fail. Transmission when fails will cause severe vibrations or will seize up. Dealership has no specific information about technical bulletins but service persons (off record) confirm increasing number of units being presented for repair.

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.

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.

The contact owns a 2005 Nissan Xterra. The contact stated that the radiator fluid leaked into the transmission, causing the transmission to seize. In addition, the cooling system failed. The radiator and the transmission were repaired by a local mechanic but the cooling system was not repaired. The manufacturer was not notified of the failure. The failure mileage was 82,000 and the current mileage was 131,000.

Vehicle experienced problems with following leakages: 1. Oil leak/ 2. Coolant leaks, and 3. Continuous transmission fluids leaks, on which dealer was still working on.

2006 Nissan Xterra. Consumer complaint against manufacturer regarding faulty radiators the consumer stated the transmission cooler is inside the radiator and it is leaking, allowing anti-freeze to enter the transmission and vice versa. When the anti-freeze leaked into the transmission fluid, it destroyed the cooling system and consequently the radiator and transmission needs to be replaced.
