general problems of the 2008 Nissan Frontier

The contact owns a 2008 Nissan Frontier. The contact stated that while driving at speeds over 40 mph, the vehicle would shake and vibrate. The vehicle was taken to the local mechanic who diagnosed that the radiator fluid had leaked into the transmission causing severe damage to the transmission. The contact was informed that the transmission and radiator needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure but no assistance was offered. The failure mileage was 86,000.

The transmission cooler integrated into the radiator failed damaging the transmission by cross contamination of fluids. Loss of power on a narrow country mountain road was not safe. I learned that this problem is very common. I feel that Nissan should have replaced the radiator before thousands in transmission damage occurred.

Transmission fluid cooler integrated in the radiator that allowed engine coolant to mix with and contaminate the automatic transmission fluid causing damage to the transmission. Radiator had to be replaced along with flushing out of the trans fluid at a service station costing a few thousand of dollars. Months later the check engine light went on and found out that the transmission is slipping caused by the fluid contamination.

Driving on street truck began to shake and vibrate I loss power and car couldn't shift into gear it seemed I pulled over and stopped and shut off. Car I started it began to drive and it wudnt go over 30mph I stopped and noticed leaking under the truck towards the engine and when I pressed on gas it wouldn't go still so I stopped and got towed.

First long trip since I bought the used truck, a trip to oakridge, 90 mile round trip from home. The truck made it back to our driveway, then when I put on the break for my husband to get out, it would not move and all the dash lights came on. I couldn't budge the truck. It was locked up. Couldn't move the stick. The engine quit. Forced it into park and tried to restart, but not a sound. The neighbor came over with his code reader. It said p1000. Battery checked good, got a new one anyway because its age. Grounds were good, but cleaned anyway. Had it towed to dealer. They put a new transmission in.

I was driving my vehicle but it seem like it wasn't getting power. I shut it off and then it would not start. Add the starter replaced still and start the ate up fuse was blown. Ticket to electrical shop they could not find anything wrong with it. Took it to the dealer they said it was the brain ecu and then they said that it was the brain and the transmission and the transmission was no good cost $5500 to fix.

I was driving my vehicle in a parking lot, but it seemed like it wasn't getting power. So, I shut it off and when I tried starting it again the fans and lights came on but nothing else. I took it to firestone and they said it was the starter. They replaced the starter and that didn't fix the problem. They changed the atecu fuse. It started and ran for three minutes and then died again. Then I took it to an electrical shop. They couldn't find anything wrong. Then I took it to the Nissan dealer and they said it was the brain ecm. They fixed that and it still wouldn't start the car. Then they said it was the ecu and transmission. They said the transmission was no good due to cross contamination (radiator fluid into the transmission). This is a Nissan defective radiator and they charged $5500 for a mistake that wasn't my fault.

Noticed shaking in passenger side front tire. Took to transmission shop after doing thousands of dollars of worked to the front end. To find out that the radiator and transmission were mixing fluid. Shop told me transmission it is done and must be rebuilt and radiator must be rebuilt. Been told this is a common problem with the Frontier.

My coolant mixed with transmission fluid. Causing it not to accelerate. Nissan mechanic says it'll cost 6000 dollars to completely fix. Absurd!!!!!! 120,000 mile vehicle.

Radiator that controls the transmission coolant let go causing the transmission coolant to mix with the engine coolant. I had the transmission repaired at new river Nissan back in 2018. Before I had Nissan repair it I had taken it to a transmission shop where it was flushed out and a small radiator added to the truck because of the radiator going bad . The truck had less than 80,000 miles on it and less than a 9 years. As the recall was added to that after all the problems from the radiator. I fill like I should be reimbursed for everything that I paid out which was about 3500. 00 total. But now it's still mixing coolant after being serviced by a Nissan dealer.

This is in regards to an item already under investigation by the NHTSA. I am another victim of Nissan's leaking transmission cooler leading to a catastrophic transmissoin failure. My transmission locked in second gear upon accelerating from a stop sign. Fortunately I was 1/2 mile from my home on a side street and not on the interstate where such a problem could lead to an accident. Consumers need to know about this problem. The fix is relatively cheap before the transmission cooler begins to leak. Unfortunately consumers are unaware of the issue until it is too late, and the repair requires a new transmission and radiator costing $5000 to $6000. Although no wreck was involved in my incident, the potential for an accident is definately present if such a failure where to happen on a congested interstate.

Transmission completally contaminated with coolant and car did not move anymore. Start slpping in overdrive. Ones I started and it has a weird sound and went home but in the way the car stops completally.

Radiator coolant leaking into transmission. Resulting in a failed transmission while driving. Very dangerous started slipping gears. Only 52000 miles on truck.

After the engine light went on on my Frontier, I took it to the mechanic. Mechanic states that I have a faulty coolant. Its a known issue by Nissan Frontiers. Basicly the coolant will leak into my radiator which then will mess up the transmission. This will cost me about $4000. 00.

While driving down rural highway (two lanes in each direction) in the right lane, truck suddenly began to buck and slowed dramatically. With a loaded bed in the truck, it was fortunate that there weren't too many people on the road at the time of the incident. Limped vehicle home on secondary roadways.

Heard a high pitched whining noise coming from the engine of my Nissan 2008 crew cab 4 wheel drive Frontier. Made an appointment to have the issue evaluated at the same Nissan dealership where I purchased the vehicle (Nissan of atlantic city - formerly admiral Nissan). I purchased the used Frontier in June 2011; approximate mileage was 40 - 41k. I also purchased an extended warranty at that time - 48 months, 48 thousand miles (expiration 6/15/15). After evaluating the problem, a Nissan service manager told me that the noise was coming from the timing chain and its components - cost of repair $1900. 00 - 2000. 00 plus 7% sales tax. I asked him if the repair was covered by the extended warranty I purchased. He said no! he informed me that my extended warranty had expired for mileage; I was over by a few hundred miles. This is an existing problem. Nissan had know of, and been dealing with this issue well before I purchased my 2008 Frontier in June 2011. However, this information was never made available directly to the consumer. When the engine whine first began it was low - barely noticeable, but the more I drove the worse it got. If I had been aware of the service bulletins sent to the the dealers about this issue, I would have had the vehicle checked out before the warranty expired; the extended warranty had a $50. 00 deductible. My final cost for the repair on 3/28/15 was $1974. 16. Nissan of America is at fault and so is the dealership - Nissan of atlantic city. They are both responsible because they both had the information about existing timing chain problems and failed to disclose it.

Trans slips on and off (specially with o/d on), when pulling without o/d is less noticeable, re engaging of speed becoming more and more and abrupt and stepped, dangerous and annoying.

Transmission needs replacing.

While vehicle is in motion and being driven down a city street or highway and making a turn the transmission goes from in forward motion (drive) to neutral (no motion, but acceleration of engine continues) for a period of 5-8 seconds, and then the transmission engages into forward motion (drive) with a large jerkking motion or thud. This happens at stop lights, and while in motion crossing highways, city streets, and when in motion making turns on highways and city streets, or from stoplights. Cause is unknown, have not found a mechanic who can diagnose the cause, have had transmission fluid changed with no improvement in the problem. This problem occurs at least three to five times per week.

I just had to have the radiator replaced and the automatic transmission rebuilt at a cost of almost $3,000 in my 2008 Nissan Frontier se 4v 2. 5 with only 84,000 miles because of the cross contamination. According to carcomplaint. Com, the average owner is becoming aware of a problem at 94,565 miles. If Nissan would have recalled the radiators immediately upon knowledge of the defect, it would have saved them from dealing with numerous transmission replacements and customer satisfaction concerns. I brought my truck to the Nissan dealer and I was told by the service manager that the problem was not caused by contamination and I should get help from Nissan who later on denied help for me. The next day I brought my Nissan Frontier to a shop expert in transmissions and their diagnosis was that the failure in my transmission was caused by an "anti-freeze contamination, code 1751". Nissan knew that they had a faulty radiator and instead of recalling the radiator, they extended the warranty knowing that the majority of the cars would surpass 80,000 miles before they started having problems with the transmission. Now looking at high cost to fix the timing chain cover seal. Nissan knows about both of these issues and is not taking responsibility and won't help.

I have the well documented problem with the radiator coolent entering and damaging the transmission. I am having it repaired a a Nissan dealership. I will have to pay over 3200. 00!. There was a settlement agreement that is rediculous!. The problem does not even occur until over 80000 miles when Nissan will not cover anything. There are hundreds if not thousands of complaints.

The contact owns a 2008 Nissan Frontier. The contact stated that while driving 50 mph, the transmission shifted erratically. The vehicle was taken to the dealer. The technician diagnosed that the transmission fluid and coolant were mixing. As a result, the transmission and radiator needed to be replaced. The manufacturer was contacted. The vehicle was not repaired. The failure mileage was 102,355 and current mileage 102,400.

A whining or buzzing type noise has develop from the timing chain area caused by excess slack in the secondary timing chains. Nissan has issued a service bulletin (ntb09-128) regarding this issue. Replacement of both secondary timing chains and their tensioner shoes will be necessary to repair this concern. My 2008 Frontier has 89k miles on it (out of Nissan's 60k warranty) and has been whining for sometime now. Nissan knows of this problem per the previously mentioned tsp. It is my worry that if the chain breaks or fails while driving it the motor will instantly stop/fail and possibly lock up therefore putting myself and family and or others at great risk for injury.

Trans cooler ruptured within radiator causing water/coolant to mix with transmission fluid destroying transmission.

Failed transmission twice due to leak of coolant caused by radiator leak. Occurred at 50k and 64k miles. First failure caused a delay after pressing accelerator allowing engine to rev before engaging when trying to accelerate from a stop. Both replacements covered by warranty.

Left rear axle seal failed and grease from axle coated caliper and brake disc, rendering braking ineffective on that wheel. This is a known issue with Nissan with a technical service bulletin (ntb100008) issued, but Nissan only selectively applies the repair. Grease coating the brake appears visually the same as brake dust, and owner's manual requires inspection of seals only every 7500 miles, so braking may be lost for a considerable period of time before discovery. Serious accident was narrowly avoided on 10-14-2011, ironically on return from dealer, when car ahead stopped in lane to turn left; hard braking and swerve into right lane avoided collision but truck stopped with front grill at same point as front seat in the stopped car.
