2017 Kia Sorento Fuel Pump: Complete Guide to Symptoms, Replacement, and Costs

If you own a 2017 Kia Sorento, here is the most important thing to know: your vehicle has two separate fuel pumps—an in-tank low-pressure fuel pump module and, depending on your engine, a high-pressure fuel pump mounted on the engine. The in-tank pump is the most common failure point, and replacing it typically costs between $500 and $1,800 at a shop, or about $150 to $1,200 in parts if you do it yourself . The job takes about 2 to 4 hours and requires intermediate mechanical skills, but following the right safety steps and using quality replacement parts can save you hundreds of dollars.

Understanding Your Sorento’s Fuel Pump System

The 2017 Kia Sorento is available with three engine options: a 2.0L turbocharged four-cylinder, a 2.4L naturally aspirated four-cylinder, and a 3.3L V6 . All three engines use an in-tank fuel pump module that sits inside the fuel tank and delivers fuel to the engine. On the 2.0L turbo models, there is also a high-pressure fuel pump on the engine that further pressurizes fuel for direct injection . This high-pressure pump is a known weak point on some 2017-2020 Sorento models with the 3.3L V6 engine, covered by a warranty extension program .

The in-tank fuel pump module includes the electric pump, fuel level sending unit, and a strainer. It is accessed from inside the vehicle, usually under the rear seat, rather than by dropping the fuel tank . This makes the job more comfortable but still requires careful work with fuel system components.

Top Signs Your 2017 Kia Sorento Fuel Pump Is Failing

Recognizing the symptoms early can prevent a breakdown and save you from being stranded. Here are the most common signs of a bad fuel pump on a 2017 Kia Sorento:

  1. Engine won’t start or takes longer to start. A failing pump cannot build enough fuel pressure for the engine to fire quickly .
  2. Loss of power when accelerating. You may feel hesitation or surging, especially when going uphill or passing another car .
  3. Engine sputtering or stalling. The pump may intermittently lose pressure, causing the engine to stumble or shut off without warning .
  4. Whining noise from the fuel tank. A healthy pump runs quietly. A loud, high-pitched whine indicates the pump is wearing out .
  5. Poor fuel economy. If the pump delivers inconsistent pressure, the engine compensates by running rich, wasting gas .

If you experience any of these symptoms, especially the whining noise or hard starting, have your fuel pressure tested immediately. Driving with a weak pump is dangerous because the engine can stall in traffic .

Fuel Pump Replacement Cost for a 2017 Kia Sorento

The cost to replace the fuel pump on a 2017 Kia Sorento varies widely based on where you live and whether you choose OEM or aftermarket parts. In the United Kingdom, the average price range is £588 to £924 . In the United States, professional replacement costs range from $500 to $1,800, with parts alone costing between $150 and $1,200 . The OEM fuel pump assembly for the 2016-2018 Sorento (part number 31110-C6200) has an MSRP of $671.18 , though you can often find it for less online.

Labor typically accounts for $100 to $400 of the total cost, depending on the shop rate and how long the job takes . Most mechanics charge between $100 and $150 per hour, and the repair takes about 2 to 4 hours .

DIY Replacement: Step-by-Step Guide

If you are comfortable with basic car repair and have the right tools, replacing the in-tank fuel pump on a 2017 Kia Sorento is a manageable weekend project. The job is rated as intermediate difficulty and takes about 2 to 4 hours .

Safety First

Working with gasoline is dangerous. Follow these precautions without exception:

  • Work outside or in a very well-ventilated area. Fuel vapors are flammable .
  • No smoking, no sparks, no hot work lights. Use an LED work light instead .
  • Relieve fuel pressure before disconnecting any fuel line to prevent spray .
  • Disconnect the negative battery cable before opening the fuel tank module .
  • Keep dirt out of the tank. Contamination can ruin the new pump .
  • Have a Class B fire extinguisher nearby .

Tools You Will Need

  • Safety glasses and nitrile gloves
  • LED work light
  • Trim removal tool set (for prying up interior panels)
  • Flat-blade and Phillips screwdrivers
  • 10mm socket, ratchet, and extension bar
  • Needle-nose pliers
  • Fuel line quick-disconnect tool set (specialty tool)
  • Fuel pump lock ring tool (specialty tool)
  • Torque wrench (in-lb or Nm)
  • Shop towels and a catch pan
  • Vacuum or compressed air blow gun (for cleaning debris)
  • Marker pen

Parts You Will Need

  • Fuel pump module assembly (compatible with your engine)
  • Fuel pump module tank seal / O-ring
  • Fuel line retaining clips (set)

Step 1: Relieve Fuel Pressure

Remove the fuel pump fuse or relay from the fuse box (consult your owner's manual for the diagram). Then start the engine and let it run until it stalls. This drains the fuel pressure from the lines. After the engine stalls, turn the key to the Off position and loosen the gas cap to relieve tank vapor pressure .

Step 2: Access the Fuel Pump Module

The fuel pump module is located under the rear seat on the driver's side. Remove the rear seat cushion by lifting the front edge and pulling it forward. You will see a metal access cover on the floor. Remove the screws holding the cover, then clean the area thoroughly with a vacuum to prevent debris from falling into the tank .

Step 3: Disconnect the Module

Carefully disconnect the electrical connector from the top of the pump module. Use the quick-disconnect tool to release the fuel lines. Place a catch pan under the area to catch any residual fuel. Use the lock ring tool to turn the large retaining ring counterclockwise. Lift the pump module straight out of the tank. Be careful not to bend the float arm on the fuel level sending unit .

Step 4: Install the New Pump Module

Compare the new pump module to the old one to ensure they are identical. Transfer the rubber seal or O-ring to the new module if it is not pre-installed. Lower the new module into the tank, making sure the float arm is positioned correctly. Install the lock ring and tighten it clockwise using the lock ring tool. A torque wrench set to about 30-40 ft-lb is recommended but not strictly required. Reconnect the fuel lines and electrical connector .

Step 5: Prime and Test

Reinstall the fuel pump fuse or relay. Reconnect the negative battery cable. Turn the key to the On position (without starting) for about 5 seconds, then turn it Off. Repeat this two or three times to prime the fuel system. Start the engine and check for leaks at the pump module and fuel line connections. Let the engine run for a few minutes and verify that the fuel pressure is stable .

High-Pressure Fuel Pump: A Special Note for 2017 Sorento Owners

If your 2017 Kia Sorento has the 3.3L V6 engine, there is a known issue with the high-pressure fuel pump. Kia issued a Technical Service Bulletin (TSB WTY034) that covers a warranty extension for the high-pressure fuel pump on 2017-2020 Sorento models with the 3.3L engine, produced between January 24, 2018, and October 26, 2020 . The problem is that the fuel control valve plunger may wear unevenly and become stuck in the open position. This can cause rough running, engine hesitation, a check engine light with code P0088 (Fuel Rail/System Pressure Too High), and in rare cases, the engine may shut off while stopped .

The warranty coverage for this repair is extended from 5 years/60,000 miles to 15 years/180,000 miles, whichever comes first, from the date the vehicle was first put into service . If you have a 2017 Sorento with the 3.3L V6, check your production date and look for the P0088 code. If you are experiencing symptoms, take your vehicle to a Kia dealer for diagnosis. The fix involves replacing the high-pressure fuel pump with a kit (part number 35399 3L444QQK) that includes new bolts and a high-pressure fuel pipe .
