2007 Nissan Frontier power train problems

“In December 2023 I noticed a bad discoloration of the coolant in my 2007 Nissan Frontier. I took the truck to the local Nissan dealership and had them flush the coolant system. There were no warning lamps or messages. There were no other symptoms or problems prior to that. Receipt available for this service. Then in May 2023 the transmission began shifting extremely hard. Upon checking the coolant it was the consistency of strawberry milkshake. The truck was taken to a local transmission shop and they rebuilt the transmission assembly along with replacing the radiator and flushing the system. This work was completed June 3, 2024. Receipt is available for this service. With continuing to see the coolant have a consistency of strawberry milkshake, I reached out to the local Nissan dealership for them to tell me there had been a recall for this. Upon doing further research, I have learned there actually wasn't a recall but an extended warranty offered that Nissan did not willingly let owners know about. $4,500.00 later I still have the same problem I started with and am fearful this truck will fail as I'm driving on the highway and am concerned about my safety.…”

“The radiator cracked, leaking water in to the transmission cooler, causing contamination of the transmission fluid. The caused the transmission to instantly malfunction, ruining all internal electronic parts. No warning signs, service lights, etc. before the transmission was damaged. Transmission repair shop says this is very common and is going to cost $3900 to repair the vehicle.”

“This is known problem you refused to force Nissan to recall. At a minimum Nissan should have been required to notify owners of the problem. They did not. My radiator has failed allowing coolant to mix with the transmission fluid destroying the transmission. I have 96,000 miles on my vehicle. I would have gladly paid out of pocket to replace the defective radiator to save the transmission, but since I was not notified of the problem, now I have to potentially replace the transmission.”

“I was driving down my driveway and my truck just wouldn’t move i always fill my fluids and get flushes on time when I got my last oil change they said there was milked goo goo in my coolant”

“I, just found that Nissan had a malfunctioning in the 2007 Nissan Frontier pick up trucks. I, have 2007 Nissan Frontier LE truck where my transmission has been acting up. Have, to give it alot of rpms for it to take off, but once it gets going its does ok. Keep, in mind it doesn't down shift down at all and the OD light stays on. Could, you please help me? Could, it be a blown fuse? My, cell is [XXX] email is [XXX].”

“2007 NISSAN FRONTIER CREW CAB: ENTERING THE 100,000 MILE MARKER THE TRUCK STARTED TO FEEL LIKE IT WAS SKIPPING. THEN THE TRUCK STALLED WHILE AT THE GROCERY STORE. I TRIED TO GET IT STARTED AND AFTER 15 MINUTES IT DID START. AAA TESTED BATTERY, STARTER AND ALTERNATORS. THEY WERE ALL FINE. LATER DROVE TRUCK TO CONTINUE GROCERY SHOPPING AND IT STALLED IN THE MAIN TRAFFIC LANE. PUSHED TRUCK TO SAFER PLACE. THEN IT STARTED AGAIN. AUTOZONE COMPUTER TEST REVEALED SENSOR P)335 AND A RECOMMENDATION TO REPLACE FLYWHEEL. INTERNET SEARCH REVEALED ISSUES WITH POWER TRAIN AND ANTI FREEZE ENTERING THE TRANSMISSION DUE TO FAULTY PARTS. NEARLY 3000. REPORTS OF SAME ISSUE. DISAPPOINTED THAT NISSAN DID NOT TAKE RESPONSIBILITY FOR THEIR USE OF COMPROMISED MATERIALS IN BUILDING THEIR CARS AND TRUCKS. IF NISSAN IS USING FAULTY OR WEAK MATERIALS, THEN MIGHT AS WELL BUY AMERICAN.”
