Kia bulletin PI2002B
Kia filed this with NHTSA as a service bulletin dated Feb 24, 2026, received Sep 3, 2020, about the engine and engine cooling — 13 documents under this number: PI2002B_OWNR_701, PI2002B_OWNR_601, PI2002B_OWNR_501, PI2002B_OWNR_401 and more. It names 1 model year (2016). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTSB - PRODUCT IMPROVEMENT CAMPAIGN (PI2002B) - NU 2.0L GDI - KNOCK SENSOR DETECTION SYSTEM (KSDS) LOGIC IMPROVEMENT - This bulletin provides information related to a software update to the Engine Control Unit (ECU) to install the Knock Sensor Detection System (KSDS) in order to protect the engine from excessive connecting rod bearing damage. This update is for some 2014-2016MY Soul (PS) vehicles produced from July 21, 2013 through August 11, 2016 equipped with Nu 2.0L GDI engines. The KSDS detects vibrations indicating the onset of excessive connecting rod bearing wear. It is designed to alert the driver at an early stage of bearing wear before the occurrence of severe engine damage, including engine failure. If vibrations caused by bearing wear start to occur, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Limp Home Mode. This will reduce further damage to the engine and ensure that the vehicle occupants are not exposed to the risk of a more severe engine failure. At that time, Diagnostic Trouble Code (“DTCâ€�) P1326, specific to the KSDS, will be recorded in the ECU. The vehicle can continue to be operated for a limited time in Limp Home Mode, but it will accelerate slowly and have a reduced maximum speed. Also, engine RPMs will be limited to approximately 1800-2000 RPM.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia PI2002B a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the PI2002B repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does PI2002B cover?
The manufacturer filed it against 1 model year: 2016 Kia Soul. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
