Cross contamination coolant and transmission. Vehicle will not start. Was perfectly fine one month ago when took it to Nissan for service

- Honolulu, HI, USA

The contact owns a 2006 Nissan Frontier. The contact stated that the vehicle slowly reduced speed and came to a complete stop several times without warning. The dealer (robert woodall Nissan, 132 union St, danville, va 24540, (434) 797-1411) replaced the transmission; however, the failure continued. The vehicle was taken back to the dealer who only inspected the vehicle and was unable to determine if the failure was electrical, engine, or power train related. The contact was uncertain if the vehicle was included in NHTSA campaign number: 1V0517000 (engine and engine cooling). The manufacturer was notified of the failures. The approximate failure mileage was 108,172.

Dear Nissan service: I am the owner of a 2006 Nissan Frontier SE with approximately 124,000 miles. The vehicle was purchased used from nalley Nissan in 2012 with approximately 89,000 miles on it. The history of the vehicle was meticulous, minus that the catalytic converter had been replaced by nalley Nissan. In February 04, 2016 I had the left catalytic converter replaced at nalley Nissan. The right catalytic converter was replaced prior to purchasing the vehicle. My vehicle has already had both catalytic converters replaced. On May 11, 2018 I was advised that I need both of my catalytic converters replaced again at stone mountain Nissan. My check engine light had came on agaiinhowever, both of the catalytic converters have been previously replaced. It should be noted that this in not an inexpensive repair. I only used premium gasoline in my vehicle to ensure its proper performance and get my vehicle regularly maintained an Nissan dealerships. It is rather obvious that there is something else going on with my vehicle that is defective in nature. I had read that this is a common problems with Nissan Frontiers and Nissan Altima. I do not want to get the catalytic converts replaced at estimated $2200 and have this problem resurface again. In Georgia, we have annual emissions tests and my vehicle will not pass an emissions test. Just recently, I had taken my vehicle on a short trip to North Georgia. The engine stalled and completely lost power. I was able to get the vehicle home however, it is rather evident that something is mechanically wrong with my vehicle and just simply replacing the catalytic converters will not ensure that this problem will happen again. Is there any guidance that you can offer? regards [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Highway driving at 55 mph the engine stalled and stopped in mid-traffic resulting multiple system loss; including power steering. Warning lights that illuminated were service engine soon and, slip. Researching this combination with the associated engine failure shows a minimum failure of the cam shaft sensor and possible interference with engine cooling. Additional research shows that this a recall issue for Frontiers. But, when I entered my VIN into your system to check recalls, the reponse is that there are no recalls for this vehicle. That seems in conflict with what is being said about there being a recall and the obvious extreme danger of engine and system failures at highway speeds

I just had to replace my transmission due to a recall. Oil and water in the transmission and radiator. I did not own the truck at the time of the recall.. how can I get reimbursed "?" this is terrible!!

While driving truck on highway it occasionally felt like I was driving over rumble strips.

- Lancaster, PA, USA

The evidence of engine and power transfer evidently progressed over of days and regressed within a matter of hours, then minutes to the point where engine would barely start and obviously barely propel the truck over 10 mph w/engine dying out regardless of throttle or automatic shift position. I limped the vehicle to the nearest respected and qualified tech bob wells -total car care. This is the second time Nissan's lack of "due diligence" left customer down, all within a year or so. A frustrating, time consuming, and costly experience.

The contact owns a 2006 Nissan Frontier. While driving 25 mph, the vehicle failed to accelerate without warning. In addition, the vehicle slowed down and the contact was able to drive back home. The local dealer was not contacted or made aware of the failure. The vehicle was diagnosed by an independent mechanic who diagnosed that the radiator fluid spilled into the transmission. The radiator was replaced; however, the radiator fluid contaminated the transmission and fluid, which caused the transmission to fail. The vehicle was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer stated that the vehicle was not included in a recall and did not offer any additional assistance. The failure mileage was approximately 89,000.

When I drive on highway, my 2006 Frontier is shaking or vibrating even if I completely stop, I have 118,000 mileage. I went to my dealer and change the spark plug, change the valve gasket cover, and do oil change because the service engine went on. I did finished the service, my service advisor called my phone and he said that my truck is ready for pick up. I arrived, went to the cashier I paid $748 for the service, got my truck. Then I drove after a munite the shaking issue is still thier so I called my advisor, he advised me to bring back and do diagnos test for $150. After the diagnose test they said they found missing accelaration and need to replace 4 ignition coil for $1114 parts/labor. Unfortunately I paid $749 for the recent repair, so, because I spent a lot of money for the first repair, he only want me do 2 ignition coil replaced for $775 parts/labor

In February, 2017, the radiator on my Nissan Frontier failed. Due to a design flaw, coolant got into the transmission which ruined it. The radiator had to be replaced and the transmission rebuilt at considerable expense (approximately $6K). The radiator failure occurred on the road and I was able to limp to a service station. Fortunately, the transmission failure did not occur on the road but could have causing a very dangerous situation.

Secondary timing chain tensioner shoes wore completely down to metal

Nissan timing chain needs replaced, Nissan has not published tsb's about the issue. Costs are 4000 by Nissan. Bought truck used. If Nissan has not published any tsbs, why should a consumer have to shell out thousands of dollars to fix the issue.

While driving my 2006 Nissan Frontier the truck would not respond to the accelerator being pressed and then began jerking. The check engine light came on and it has been doing this for a couple of days. I took it to my mechanic and he said is was the radiator leaking into the transmission and destroying the transmission which Nissan knows about the defct but has chosen not to fix. If I was traveling at a high speed on the interstate and the truck did not respond to the accelerator and started to jerk a collision would have happened. The fact that Nissan knew about this defect and chose not to inform me of the problem causes considerable alarm.

Transmission is binding due to coolant leaking into transmission. Fluid is bubbled and looks like poached egg causing overheating. Transmission color is not correct, same problem as under investigation

- Owensboro, KY, USA

Driving on a trip transmission started slipping and jerking. Had to drive slow in third gear with it still slipping. Radiator fluid was foamy. Truck still in driveway. Four to five hour trip on highway with some hills didn't think I would make it home. A few years back we received a service notice of failed radiator. Took truck to Nissan and they would not replace unless there was a problem.

I have a cracked radiator that is leaking coolant into the transmission of my 2006 Nissan Frontier. When the 2 fluids mix it creates a mixture called toxic hell stew that is irreversible and will eventually kill my 5-speed automatic transmission.

Timing chains guides and tensioners used by Nissan were known by Nissan to be faulty resulting premature failure and extremely costly engine repairs

- Lindale, GA, USA

According to the mechanic, the transmission coolant reservoir (which is connected to the radiator) collapsed causing water, antifreeze and transmission fluid to mix. These fluids then made their way into the radiator, transmission and coolant reservoir. This, in turn, caused extensive damage to my transmission. My transmission then required replacement/rebuild. The first possible sign of the problem was rough automatic shifting of the vehicle. I then noticed a leak of transmission fluid from the front passenger side of the vehicle (which was parked in my driveway). This was followed by a loss of power/drivability.
