Doing general check up of my truck while performing an oil change noticed sludges in the radiator. Immediately performed bypass and drained the transmission to find it full of coolant. Fixed the issue myself after all the new parts arrived early enough to save the transmission. Honestly feel like nissan owes everyone that had this issue a brand new truck no questions asked not right so many people have been affected by this issue and the federal safety agency somehow denied the claim according to their inspection do your job slam nissan make them pay up.
2007 Nissan Frontier transmission complaints
Page 3 of 9: complaints 41 to 70 of 222, newest first, as owners wrote them.
Drivers airbag light is on. Also transmission slipping anti-freeze mixing with transmission fluid.
Our 2007 nissan frontier's radiator leaked into our transmission and ruined our transmission at 110,000 miles. The vehicle started slipping and stuttering changing gears while we were driving and it then locked up when we pulled into a gas station and we could not shift the car into gear. The car had to be towed where the shop is telling us it needs a new transmission and radiator. When I called the nissan dealership, they acknowledged this is a problem with this vehicle, but I am out of luck because it is no longer covered under warranty. The repair is over a $5200 fix. This is a direct result of a bad manufactured radiator, no fault of our own, and it has now ruined our truck.
Automatic transmission failure due to radiator failure and coolant contamination
Radiator leaks into transmission causing failure. The transmission slipped into neutral entering 45 MPH traffic on a 4 lane city street leaving me stranded and blocking traffic. It is currently in the shop and will cost 3000.00.
Vehicle overheated while driving 70 MPH on interstate, followed by automatic shift sputtering between 3 and 4th gears. Taken to mechanic and was notified that overheating was result of radiator failure, which caused radiator fluid to mix with transmission fluid. Repair cost $3400 to replace radiator and transmission. Air bag warning light illuminating 1 month after takata recall expired.
A known issue was never corrected with my vehicle causing the coolant to leak into the transmission. Nissan knew of the problem and never did anything to notify me. Yet they still send me letters asking if I would like to trade in my vehicle. My vehicle broke down in ther exact way they described it would and still, they were unwilling to help with repairs.
Nissan recognized leak in radiator, leading to corrosion in transmission resulting in clunking shifting with automatic transmission, until transmission cannot shift by itself. Secret warranty bulletin put out but only to nissan service centres and not shared with vehicles owners until to late for most. If they recalled or fixed the radiator, would not now need a new transmission repair for ~$7000. Truck will no longer go up hills unless one shifts as if it were manual
When driving my 2007 nissan frontier with a 191000 miles and truck starts to slow down, it would down shift rough. Made appt for next day with mechanic. It still being the same day I drove my son to the park and came to a stop , truck down shift was rough again and service engine soon light came on, pushed on gas and truck felt like it lost power. Got to park a block away, turned truck off and it never started again. Towed to a mechanic . $1100 later, mechanic says tow it to the nissan dealer for a diagnostic because the modular inside the transmission is not working and they can tell what's wrong. I get it towed to nissan dealer for $90 and $450(3hrs of labor to diagnose truck) later, nissan said radiator fluid cross contaminated with transmission and ruined it. Also found transmission fluid and engine oil in radiator. So the radiator and transmission needs to be replaced for $6800. Nissan dealer sends me service coupons, flyers to trade the frontier for newer a model to my house. They also text and call. In 2012 they settled to extend power train warranty because of this problem. Why wasn't I informed of preventative maintence on a known defect.
Takata recall. I went to go do a transmission flush. And mechanic says he cant flush it cause theres coolant mixed in with transmission fluid. Then engine light came on while driving home.
A crack came in the radiator, forcing coolant into the transmission, damaging the transmission.
My transmisin stop working a dont no tha problem.
While driving on a paved state highway at aprx 50mph, the vehicle slowed down and RPM's went up. Much like the transmission had downshifted. This is an automatic trans. Couldn't manually get it back to normal by downshifting or putting it into neutral. Service engine soon light was now lit. Pulled over, stopped and turned off engine. Under the hood there was no obvious sign of leaking, broken belts or smoke. Restarted the truck and drove home aprx 10 miles with no problem, but service engine soon light still on. Drove it the next day to autozone (5miles total) and showed codes p1774 and p0717. Researching the codes LED me to all the transmission replacement problems due to a failure of the trans fluid cooler inside the radiator which mixes that oil with coolant and destroys components inside the transmission and requires replacement. Now I have to figure what to do facing a $6000 repair bill on a $10000 vehicle. This had me losing speed in a traffic situation that could have been dangerous and stranding us as an elderly couple with a disabled person in the arizona desert. Money aside, it's pretty sad to find out that the federal safety agency and nissan have known about this problem for years and neither has taken any proactive steps to inform or warn the owners. Just a lot of collecting info and waiting for the vehicles to be carted off as junk and the problem swept under the rug. Thanks a lot for stalling for years and doing nothing. Safety doesn't just pertain to how many people died! Not exactly the right thing to do!
Transmission failure due to coolant mixing had to have the valve body replaced along with the tcmand new radiator. Vehicle cut completely off and would no longer start. After failing to excelerate past 40mph.
Radiator leak resulted in replacing radiator and damaged transmission
Defective radiator hose caused coolant fluid to seep into the transmission, damaging it entirely. Cost of repairs were $4200.00. Nissan neglected to notify owners of defective part and the recall for 2005-2010 models. Over 2000 complaints were filed before nissan took corrective action, which included extended warranty to 100,000 miles. However, mechanical issues will not manifest until well over 100,000 miles thus absolving nissan from any responsibility or ownership.
Transmission radiator contamination. Loss acceleration on hi way.
Tl* the contact owns a 2007 nissan frontier. After stopping at a stop sign or red light, the vehicle hesitated to respond when the accelerator pedal was depressed. The instrument panel gauges illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the valve body needed to be replaced. The vehicle was repaired on two separate occasions, but the failure recurred. The vehicle was taken back to the dealer where it was diagnosed that the radiator and transmission fluid mixed together. The radiator and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 108,000.
When entering hwy 17 (70 MPH speed limit) I pressed the gas pedal to the floor to enter oncoming traffic. Instead of increasing speed the truck stalled. I pulled onto the right side emergency lane in order to prevent traffic from running over my vehicle. I placed the transmission in park and it seemed to smooth out . Motor was running with excess RPM's and transmission was slipping. This was a near accident. I could hear cars behind placing on brakes and blowing horn. When returning home was told by nissan dealership radiator cooler and transmission had to be replaced due to faulty lines. Nissan should have recalled this problem.
Our 07 nissan frontier was being driven to be inspected for registration when, at a stop light, it just turned off and would not start. We had it towed to a mechanic. He had to send it to the local nissan dealership for the computer to be replaced and reprogrammed. According to this mechanic, the leak from the radiator has mixed with transmission fluid in the transmission causing all these components to fail and need replacing. This is unacceptable!!
Tl* the contact owns a 2007 nissan frontier. While the vehicle was being serviced for an oil change, the contact was informed of a leak in the radiator. The vehicle was taken to the dealer where it was diagnosed that the radiator was defective and was leaking fluid into the transmission. The vehicle was repaired. The manufacturer was made aware of the issue. The failure mileage was approximately 109,000. Updated 01/27/17*lj updated 01/31/17.
I have a 2007 nissan frontier with 68,000 miles. No major issues until now. Started having a transmission noise during acceleration. 10/2016, took my truck to my local auto mechanic and found transmission fluid low. No signs of leaks. Also check coolent and no problems seen. 11/5/16 I head a pop and saw fluid running out of coolent overflow. Transmission stated slipping. 11/9/16 took truck to my local auto repair shop and they see the coolent is mixed with oil. On 11/15/16 per my local nissan dealer I have a crack in my trans coolent system which is mixing transmission and coolent fluid. In result damaged my transmission and requires replacement. He had ask me to call nissan for addition assistance. I was also told by my local nissan dealer that this problem could have been resolved by a radiator replacement. On 11/9/2016 I contacted nissanusa and I was hung up on twice. I finally got in touch with a decent person the set me up with a case. I asked for a description of the details of the warranty and they said it would be emailed. 11/15/2016, I'm still waiting for that email. I called again after getting one rude person and was put on hold then disconnected. I called back asking for financial assistance. I should be getting a call tomorrow. Also, I was told about the issue a year or two ago by another nissan owner. When I contacted my local dealer to acquire about the problem and aware to they knew nothing about it. Also, they did not have info of any preventive measures the could prevent this problem. If this was a know issue the we should have been notified by nissan.
The truck began losing power because it would not shift into lower gears. This put us at risk at higher speeds. The problem got worse and we took it to the nissan dealer. We learned that nissan knew of the issue, but failed to notify us. They knowingly let us drive a dangerous truck for years.. We were lucky we brought it in when we did. We always had our truck repaired at the nissan dealer, they had numerous opportunities to tell us, or write us. We have not moved! This is wrong and the class action lawsuit settlement is unfair to those of us who happened to have the issue at mileage over 100,000. The judge should have required nissan to warn us. We are going to have to pay $5000 to have this repaired, we already paid $200 dollars in new fluids thinking that was the issue.
The transmission fluid cooler in the radiator has busted causing radiator coolant to get inside the transmission. When the coolant mixed with the transmission fluid it has caused catastrophic damage to the inside of the transmission (gears, etc.) a couple of weeks ago I noticed the transmission starting to shift more and more abruptly. I drove to work and at the end of my shift, my truck would not start. I discovered the reason for it not starting was due to the automatic transmission fuse was blown. I replaced the fuse, started the truck and the fuse blew again. I took it to a mechanic and he discovered the issue with the radiator and transmission. This is a recurring issue with 2005 -2010 pathfinder, frontier and xterra owners. What can be done to hold nissan accountable for a faulty product that they are obviously aware of but will not correct. This is going to cost me $3500 - $4500 to repair
My radiator had failed causing transmission fluid to enter the coolant and coolant to enter the transmission. Once nissan replaced the radiator and flushed out both systems, the transmission seem to drive ok, and the nissan dealer said it seems to be ok. After driving the vehicle for a month the transmission has developed slippage due to the previous radiator with an internal transmission cooler that caused internal damage to the transmission. If nissan had built the truck with an external transmission cooler separate from the radiator, I wouldn't have had an issue with the transmission once the radiator failed. As an ase certified mechanic with working in the industry for 10 years, also serving in the military as a maintenance mechanic, and with all the different models of vehicles that I have owned; have I ever had this problem where one component fails that would cause me to replace a transmission. I am starting to believe that nissan is not any better than owning any other car, as the technology seems to not be getting better but more costly to us the consumers. The vehicle was drivin at about 30 MPH when the truck temp gauge elevated, and coolant burping out. I immediately shut it down to check and discover the issue was the radiator. Once taken to the shop by tow truck the shop said the transmission fluid had coolant inside and transmission fluid inside the engine coolant area and passages.
Lights on dash came on while in park and engine running. Took it to dealer, and was notified that the radiator coolant had leaked into the transmission. Repair will cost $5,900.94 for new transmission and radiator. I had no idea that anything that serious was going on. I felt no issues while driving.
Tl* the contact owns a 2007 nissan frontier. While attempting to start the vehicle, it failed to start. The vehicle was towed to an independent mechanic where it was diagnosed that the radiator was leaking into the transmission. The vehicle was then towed to an authorized dealer where it was confirmed that the radiator was the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 102,000. The VIN was not available.
The federal safety agency action number 12004. This week my 2007 nissan frontier's transmission failed at roughly 62,000 miles. I had the vehicle towed to my nearest nissan dealer where they informed me that it failed due to a leak in the cooling system causing coolant to leak into the transmission causing the failure. They also informed me that this has been such a problem that nissan "extended the warranty" to help fix the problem. The only issue is that the deductible for the "warranty" is $3,000! That does not seem like much of a warranty to me. I feel like nissan has admitted the problem and is trying to avoid a recall by issuing the extended warranty with a deductible that is most likely covering a majority of the cost of the job if not entirely. Since this investigation is still open I thought it only appropriate to contribute.
Transmission and coolant mixed causing the transmission not to shift properly in traffic. Nissan is aware of their faulty components and should be forced to recall and fix, at their expense.
Trans cooler defected causing water to enter transmission and transmission is not longer functioning.
