2018-2019 Nissan Kicks Front Seat: Decoding S, SV, and SR Trim Differences

Variant Differences: The Critical S/SV vs. SR Distinction

The single most important factor when replacing a front seat in a 2018-2019 Nissan Kicks is the vehicle's trim level. The seats are not interchangeable between the base (S, SV) and sport (SR) trims due to differences in upholstery, features, and sometimes wiring. Failure to match the trim will result in a part that doesn't fit, has incorrect electrical connectors, or doesn't match your interior.

• S and SV Trims: These models use a standard, durable black cloth upholstery. They are manual, non-heated bucket seats.
• SR Trim: The SR trim features a unique "sport cloth" upholstery, which is often accented with distinctive orange stitching. Some SR models were available with an optional Premium Package that included heated front seats and simulated leather (leatherette) upholstery.

Common Failure Points and Symptoms

While generally durable, the front seats can develop issues over time. Some problems are simple mechanical failures, while others can affect the vehicle's critical safety systems.

• Seat Will Not Adjust: The most common reported issue is the seat getting stuck on its tracks, unable to move forward or backward. This is often caused by a problem with the seat adjustment bar. Nissan has issued a Technical Service Bulletin (TSB) to address this specific problem.
• Seat Wobble or Looseness: A feeling of movement or a clunking noise from the seat base during acceleration or braking can indicate loose mounting bolts or a failing seat track mechanism. This is a serious safety concern that should be addressed immediately.
• Airbag Warning Light: An illuminated airbag light on the dashboard can be caused by a fault in the seat's wiring, the side airbag, or the passenger Occupant Classification System (OCS) sensor. This often happens after a seat has been removed and reinstalled if the connectors are damaged or not plugged in correctly.
• Worn Upholstery and Collapsed Foam: High-mileage vehicles may exhibit torn fabric, split seams, or collapsed foam cushions, particularly on the driver's side bolster, leading to discomfort.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

For the 2018-2019 model years, Nissan has addressed a few seat-related issues.

• TSB NTB22-018A: This bulletin specifically addresses manual front seats that will not move forward or backward. The cause is identified as an issue with the seat adjustment bar, and the fix involves replacing the bar. The procedure requires removing the seat from the vehicle.
• TSB NTB19-071C: This TSB relates to a stored Diagnostic Trouble Code (DTC) B00A0-00, which points to a fault within the Occupant Classification System (OCS). This system is critical for proper passenger airbag operation.
• Recall for Backup Camera: While not a seat issue, many 2018-2019 Kicks were recalled because the backup camera display settings could be adjusted to not show an image.

No major recalls for the front seat structure or airbags were found specifically for the 2018-2019 Nissan Kicks. However, other Nissan models have had recalls for seat-related issues like faulty welds or OCS sensor problems, highlighting the importance of these components.

Buying a Used 2018-2019 Kicks Front Seat: A Buyer's Checklist

Purchasing a used OEM seat is an excellent way to save money, but careful inspection is key to getting a safe and compatible part. New OEM seat assemblies can be extremely expensive, often costing several thousand dollars. A used OEM seat provides the same factory fit and safety standards at a fraction of the price.

Step 1: Verify Trim Level (S/SV vs. SR)

This is the most crucial step. Ask the seller for the VIN of the donor car to confirm its trim. Look at photos closely: SR seats will have upgraded sport cloth and may have orange stitching. S/SV seats will have plain black cloth.

Step 2: Inspect the Upholstery and Foam

Check for rips, tears, stains, and cigarette burns. Pay close attention to the outer bolster on the driver's seat, as this is a high-wear area. Squeeze the seat cushion and backrest to ensure the foam is still firm and supportive, not collapsed or flattened.

Step 3: Examine the Seat Frame and Tracks

Look for any signs of rust, bending, or cracks in the metal frame and mounting points. Place the seat on a level surface and try to wiggle it; there should be no excessive play in the tracks or recliner mechanism. Operate the manual adjustment lever to ensure the tracks slide smoothly through their full range of motion.

Step 4: Check All Electrical Connectors

Carefully inspect the yellow airbag connector and any other electrical plugs under the seat. They should be intact, with no broken clips or bent pins. A damaged connector will trigger an airbag warning light and may prevent the safety systems from working in a crash.

Step 5: Verify the Seat's History

Ask the seller if the seat came from a vehicle that was in a collision. Seats from cars involved in significant accidents, especially side impacts, should be avoided. The internal structure, airbag, and seat belt pre-tensioner may have been compromised in ways that are not visible.

Replacement Guide

Installation Difficulty: 2/5

Replacing the front seat is a straightforward mechanical task, but requires extreme care when handling the airbag system wiring. The main steps involve disconnecting the battery, unplugging connectors, and removing four mounting bolts.

Step-by-Step Walkthrough

1. Disconnect the Battery: This is a mandatory safety step. Disconnect the negative battery terminal and wait at least 3-5 minutes for the airbag system's backup power to discharge completely. Failure to do this could result in accidental airbag deployment.
2. Move the Seat: Slide the seat all the way back to access the two front mounting bolts.
3. Remove Front Bolts: Remove the two bolts holding the front of the seat tracks to the floor. These are typically covered by plastic trim pieces that pop off.
4. Move the Seat Forward: Slide the seat all the way forward to expose the rear mounting bolts.
5. Remove Rear Bolts: Remove the two bolts at the back of the seat tracks.
6. Disconnect Wiring: Gently tilt the seat backward to access the electrical connectors underneath. Carefully unplug the main harness and the yellow airbag connector. There are usually small tabs that need to be pressed to release them.
7. Remove the Seat: With all bolts and wires disconnected, you can now lift the seat out of the vehicle. Be careful not to scratch the door sills or interior trim.
8. Installation: Installation is the reverse of removal. Place the new seat in the car, connect the wiring harnesses (ensure they click into place), and loosely thread all four mounting bolts. Torque the bolts to factory specifications before reconnecting the battery.
