What 21 owners told NHTSA about the 2020 Nissan Titan

The contact owns a 2020 Nissan Titan. The contact stated that while driving at an undisclosed speed, the vehicle intermittently stalled; the contact waited several minutes for the vehicle to return to normal operation. The Check Engine warning light was illuminated. The failure had occurred on several occasions. The contact researched and was made aware of an unknown recall; however, the VIN was not under recall. The vehicle was taken to a dealer where it was diagnosed and determined that the fuel temperature valve needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed and determined that the radiator needed to be flushed and refilled. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 85,000.

from day one, it has had a hesitation on acceleration from both still and moving normal highway speeds. rarely is acceleration steady, smooth and immediate. dealer has had for regular oil change and this problem has been reported every time . answer was that factory recall was performed and should be better. but NO. over a year now, several visits and nothing resolved. a couple times when i needed that immediate acceleration but with severe hesitation and a semi truck hitting his brakes and blowing horn i would call it a safety problem. im not sure what work was preformed, assuming most time transmission but after research on computer there have been nissans with engine components causing this. please help. where do i go from here?

The problem I am writing about concerns this vehicle and recall #PC773 EGI HARNESS. Reference must also be made to Nissan #NTB20-89 dated December 8, 2020. I purchased this vehicle from Bates Nissan (5501 East Central Texas Expressway, Killeen TX 76543, 254-781-3837) on February 18, 2021 used with 5448 miles. I was told that it had been owned by an employee at the dealership. It is my understanding, as described in NTB20-89, that a Nissan initiated "stop sale" was put into effect in December of 2020. However, Bates Nissan failed to complete this recall prior to selling it to me and did not inform me that there was an open recall on this vehicle. On July 22, 2022 I had a Nissan dealer (LeBrun Nissan, 396 Grant Ave, Auburn NY 13021, 315-253-7700) attempt to perform this recall. The technician did not find any evidence of visible damage on or near the transmission power wires OEM splice, however step 25's "continuity test" of the transmission power wire failed. I am a highly skilled engineer and have reviewed NTB20-89, and find that the transmission power wire continuity test to battery ground is flawed for the following reasons. 1) The process does not isolate (disconnect all ends) the transmission power wire. Therefore, it quite likely that some DVOM's will show continuity to battery ground causing a false positive. 2) Since the recall is to determine if this wires insulation has failed, a continuity test is not appropriate since it cannot measure the integrity of the wire insulation. Therefore, this test could also test as a false negative and allow vehicles to return to service with insulation that is still compromised/weak. Instead, an insulation dielectric test should be performed on this wire. Issue #2 is concerning, since vehicle safety may be at risk and is the primary reason I am informing NHTSA. My hope is that NHTSA has technical people that can review NTB20-89 and discuss with Nissan. I have no confidence that Nissan can fix this issue.

I WAS SITTING AT A LIGHT WAITING TO TURN LEFT. THE ENGINE STARTED TO IDLE AT ALMOST 2000 TOMS. I WENT TO ACCELERATE TO TURN LEFT AND I HAD COMPLETE LOSS OF POWER IN THE INTERSECTION. THE ENGINE WOULD NOT GO ABOVE IDLE SPEED OF ABOUT 1100 RPM. THE CHECK ENGINE LIGHT CAME ON. I HAD TO PULL OVER. THE CODE READER SAYS THE IDLE AIR CONTROLLER HAS A FAULT. THIS IS THE SECOND TIME THIS HAS HAPPENED BUT THE FIRST TIME IT HAPPENED.IN A DANGEROUS INTERSECTION.
