2012 Nissan Frontier Problems

What owners report

Owners of the 2012 Frontier most often report the automatic transmission shifter refusing to move into Drive, and a flashing air bag/seat belt warning light that dealers trace to the passenger seat cushion or belt pretensioner. Engine stalling and repeated camshaft sensor replacement also come up, along with rear leaf spring and axle seal leaks at higher mileage.

   Transmission shifter will not move into Drive

   • 11 complaints (14%)
   • median 34,214 mi at 3.3 yrs old (11 state mileage)
   • filed 2015

   Owners describe turning the key or starting the truck and finding the column shifter will not move out of Park or into Drive, leaving the vehicle stuck where it sits. Several complaints come from fleet operators who say several 2012 Frontiers in the same fleet had the same failure, and that the dealer replaced the shifter assembly. Some owners report the repair was declined as out of warranty, and a few mention the part is dealer-only and costly. Reported mostly between roughly 19,000 and 52,000 miles, often with no warning.

   What to check: With the engine running, cycle the shifter through every gear including Park and Drive and confirm it moves freely and the dash indicator matches. Ask whether the shifter assembly has ever been replaced.

   An excerpt from owner complaints in NHTSA records

   “Vehicle became hard to put into gear, especially when cold. Took car to the dealer, and they said something must have spilled down by the shifter linkage. I am the only driver, and I do not think that was the case, but could not be absolutely sure. I am only submitting this, because I saw several other posts where people could not shift their vehicles out of park, Nissan would not help out with the expense of repair since they were out of warranty. Anyone reading this should think long and hard before purchasing a Nissan. …”

   Air bags

   Flashing air bag or seat belt warning light

   • 21 complaints (26%)
   • median 57,000 mi at 5.8 yrs old (13 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2012–2024

   Complaints describe a red air bag light or passenger air bag light flashing or staying on while driving, sometimes along with a blinking seat belt reminder. Owners say dealers adjusted the seat belt tensioner, recommended replacing the passenger seat bottom cushion, or replaced the belt pretensioner and sensor, and in several cases the light returned after the repair. Some owners also received recall notices for an air bag control unit recalibration or an air bag inflator campaign. Reported from about 45,000 to 158,000 miles, across a wide age range.

   What to check: Turn the key to Run without starting and confirm the air bag light goes out after the bulb-check sequence rather than flashing. Ask whether the open air bag campaigns were completed and whether the passenger seat cushion or belt pretensioner was replaced.

   NHTSA complaint #11023555, filed 2017-09, 158,000 miles

   “I was hit from behind while completely stopped to make a left hand turn on a city street. The car that hit me, a 2006 Nissan altima, was travelling, I believe, between 45-50 MPH. Both vehicles were totaled. The airbag in my 2012 Nissan Frontier did not deploy. I don't believe that is normal, but Nissan will not comment. Within a week of the accident, I received a recall notification from Nissan regarding the airbag control unit not being calibrated properly. …”

   Engine

   Engine stalls or cuts out while driving

   • 9 complaints (11%)
   • median 84,653 mi at 8.0 yrs old (8 state mileage, few)
   • filed 2012–2026

   Owners report the engine quitting without warning while driving, sometimes while slowing for a light or climbing a grade, with the check engine light coming on. Complaints describe loss of power steering and brake assist once the engine stops, and that restarting took several attempts or a tow. Several say the dealer replaced camshaft or crank position sensors, and some had the same sensor replaced more than once. Reported from about 20,000 up to 180,000 miles, often at speed or during deceleration.

   Recall 11V5920002 related service bulletins

   What to check: Ask for service records showing whether camshaft or crank position sensors were replaced and how often, and check that no check engine codes are stored. A pre-purchase scan for pending codes is worth doing.

   2 excerpts from owner complaints in NHTSA records

   “The vehicle would randomly stall while driving, particularly when slowing for a traffic signal. The engine stopping would cause all power assisted functions to cease making it difficult to steer and brake. Most recently the vehicle would start extreme hesitation while driving and I could not get up to the posted speed limit of 55 MPH. I had to use my flashers to warn other drivers that my speed was only approximately 35 MPH. Also the transmission had difficulty shifting. …”

   NHTSA complaint #11330938, filed 2020-06, 77,961 miles

   “My truck has had what feels to me like a rough idle for about as long as I've had it. It was fine for several years but a couple of months ago the truck died at a stop light. It started right back up and I didn't think I'd be able to replicate this for a mechanic so I just kept driving it. It also died once on my wife but she didn't tell me about it at the time. A couple of weeks ago I was driving on the highway at lower speeds due to traffic. It died on me again and this time it wouldn't start. I had to have it towed to a Nissan dealer. …”

Buying note. Pay attention to the shifter, the air bag warning light, and any stored engine codes on a test drive, since those are the failures owners most often describe. Ask for service records and confirm whether the open air bag campaigns were completed before purchase.
