Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
SERVICE INFORMATION When diagnosing possible power steering gear (rack and pinion steering rack, or steering rack) leak issues, it may appear the steering rack is leaking when actually, it?s not. Use this service bulletin to help make a more accurate diagnosis of the steering rack. See this bulletin for further detail.
full bulletin at NHTSA ↗SERVICE INFORMATION If a customer describes lack of power or poor acceleration, perform the following checks before attempting any repair: * Check for stored DTCs. * Check if the driver is resting their left foot on the brake pedal while accelerating. Advise the customer not to rest their foot on the brake while accelerating. * Use CONSULT-III plus in Engine Data Monitor to check operation of the brake lamp circuit signal. Monitor the brake switch during the incident; it should be "OFF". Please see this bulletn for further details.

The failure pattern owners describe
The 2012 Frontier's powertrain has accumulated serious complaints across multiple systems. The most common and stranding failure is the automatic transmission shifter assembly refusing to engage Drive—at least eight vehicles in one fleet operator's lot of 66 Frontiers experienced this, with repair costs around $600 for dealer-exclusive parts. Nissan has denied warranty coverage for vehicles just 3,000 miles over the 36,000-mile bumper-to-bumper limit, despite Consumer Affairs acknowledging the pattern (Case #18171024).
Transfer case driveshaft bolts are another hazard: all six bolts attaching the front driveshaft to the transfer case have worked completely loose and detached, causing loud banging, jerking, and a vehicle drop at low speed. This occurred without adequate warning.
Rear axle breather valves rust or fail, causing pressure buildup that forces gear oil past the seals and onto brake pads. Nissan classifies this as "environmental" and refuses warranty, even though owners report it happening as early as 13,000 miles. A $15 part failure forces $1,000-plus axle replacement because seals and bearings cannot be serviced separately.
Additional complaints include harsh cold-weather shifting, clutch assembly failure at 21,000 miles, an ECM failure at 25,000 miles, and a clutch pedal safety switch grommet that fails by 15,000 miles, leaving the vehicle unable to start.
Failure modes owners describe
Transmission shifter fails to engage Drive
Automatic transmission shifter assembly becomes inoperable, preventing engagement into Drive gear and stranding the vehicle. Multiple owners report the same defect recurring on their units and across multiple vehicles in their fleet.
When: Variable mileage; some within warranty period, others beyond 36,000-mile bumper-to-bumper coverage
Symptoms owners cite: Shifter will not move into Drive position; Vehicle becomes stranded and inoperable; Defect can occur suddenly with little or no warning
Repairs/costs cited: Shifter assembly replacement required. Parts are dealer-exclusive. Repair cost cited as $595–$600. Out-of-warranty repairs not covered by Nissan.
Recalls/TSBs owners mention: Nissan Consumer Affairs (Case #18171024) denied warranty coverage for vehicles outside 36,000-mile bumper-to-bumper period, citing mileage overage despite acknowledging high-frequency pattern in fleet vehicles. No TSB or recall issued despite multiple documented failures.
Transfer case drive shaft bolts separate
All six bolts attaching the front driveshaft to the transfer case work loose and detach without warning, causing loss of drive and potential catastrophic failure if it occurs at highway speed.
When: Reported at 181,041 miles; initial warning signs present for approximately 10 minutes before complete separation
Symptoms owners cite: Low noise associated with tire rotation sound; Loud 'bang' sound underneath vehicle; Vehicle begins jerking and makes horrible noise; Complete loss of drive capability; Front end vibration at low speed (15 mph) followed by structural drop; Transfer case and floorboard damage from detached components
Repairs/costs cited: All six bolts securing front driveshaft to transfer case were missing. Transfer case and floorboard damage documented. Extent of repair costs not stated in narratives.
Recalls/TSBs owners mention: No recall or field service bulletin mentioned despite owner assertion that all 2012 Frontier units should be inspected for this problem.
Rear axle seal leaks due to breather valve failure
The rear axle housing breather/screen valve fails or rusts, causing pressure buildup that forces gear oil past the axle seals. Nissan classifies this as 'environmental causes' and denies warranty coverage despite multiple owners reporting the same defect.
When: Reported as early as 13,000 miles on vehicles only 2 years old; another owner at unspecified mileage
Symptoms owners cite: Gear oil leaking from rear axle seals; Leaking oil contaminating rear brake pads, creating safety hazard; Rusted or faulty breather/screen component; Pressure buildup in axle housing
Repairs/costs cited: Breather valve is approximately $15 part, but seals and bearings cannot be replaced independently. Both rear axles required replacement at cost exceeding $1,000. Diagnostic fee charged even without guarantee of warranty coverage.
Recalls/TSBs owners mention: Nissan Service Centers refuse warranty coverage, citing 'environmental causes.' No recall or TSB issued despite multiple owners reporting identical defect across different vehicles.
Shifter linkage hardening when cold; difficult gear engagement
Transmission shifter becomes difficult or stuck, particularly in cold conditions, restricting the ability to select gears smoothly.
When: Particularly when vehicle is cold
Symptoms owners cite: Hard to put vehicle into gear; Condition worsens in cold weather; Unable to shift out of Park (referenced in similar complaints)
Repairs/costs cited: Dealer attributed issue to spillage near shifter linkage, though owner disputed this diagnosis
Recalls/TSBs owners mention: No formal response documented; vehicle was out of warranty
Jerking and hesitation in reverse with 4WD engaged
When 4WD 2H mode is engaged and vehicle is shifted into Reverse, a momentary hesitation and jerking occurs as if the transmission momentarily goes into Neutral.
When: Only occurs in Reverse and at low speeds
Symptoms owners cite: Momentary hesitation when reversing in 4WD; Jerking motion while backing up at low speed; Vehicle operates normally in other gears and modes
Repairs/costs cited: No repair attempted; dealer service noted condition on work order
Recalls/TSBs owners mention: Dealership technician stated this behavior is 'normal in 4 wheel drive' with no malfunction or repair recommended
Vehicle shudders without warning during driving
Vehicle suddenly shudders or shakes without warning while driving at various speeds, then returns to normal operation. No apparent cause identified.
When: At approximately 63,000 miles
Symptoms owners cite: Sudden shuddering or shaking while driving; Occurs at various speeds; Clears spontaneously and returns to normal operation
Repairs/costs cited: Vehicle was taken to dealership but was not diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer notified but no action taken
Acceleration limited to 30 mph with violent jerking
Engine power output becomes severely limited and cannot exceed 30 mph. Vehicle then begins violent jerking, throwing occupants around.
When: At 25,012 miles, very early in vehicle life
Symptoms owners cite: Vehicle will not accelerate beyond 30 mph; Violent jerking and shaking; Occupants thrown off balance by jerking; Loss of power and drivability
Repairs/costs cited: Dealer diagnosed failed electronic control module (ECM) requiring replacement
Recalls/TSBs owners mention: Manufacturer was contacted; vehicle was scheduled for repair but repair status not confirmed in narrative
Clutch assembly failure; gears fail to engage
Transmission clutch assembly fails, preventing gears from engaging and disabling the vehicle.
When: At 21,456 miles, very early in vehicle life
Symptoms owners cite: Gears fail to engage; Vehicle becomes inoperable
Repairs/costs cited: Independent mechanic diagnosed that clutch assembly required replacement
Recalls/TSBs owners mention: Manufacturer made aware but vehicle was not repaired per narrative
Clutch pedal safety switch grommet failure prevents starting
A rubber grommet on the clutch pedal that triggers the clutch safety switch deteriorates, preventing the vehicle from starting. Vehicle cannot be jump-started and must be towed or repaired on-site.
When: Reported to fail at approximately 15,000 miles
Symptoms owners cite: Vehicle will not start; Cannot be jump-started; Affects clutch safety interlock system
Repairs/costs cited: Replacement grommet costs approximately $15 and is easy to replace, but requires removal of clutch pedal assembly to access

What owners are reporting 2 most recent
The 2012 Nissan frontier has a rubber grommet on the clutch pedal which triggers saftey switch. The grommet goes bad and the vehicle will not start. Cannot be jumped. Must be towd or fixed on the spot. These grommetts go bad in 15,000 miles and it cost 15.00 for a new one. You cannot maintain a piece of rubber on te clutch. Rediculous
Without much warning signs or without any accident, all of the sudden the vehicle started jerking and made a horrible noise. After inspection by the shop, all six bolts attaching the front drive to the transfer box were gone. The parts went loose causing severe damage underneath the track, which was worsened by the towing. If that parts would have detached at high speed, the incident would have…
