P0175 on the 2024 Kia Telluride
The 2024 Kia Telluride continues as one of the most popular three-row SUVs, powered by the Lambda II 3.8L GDI V6 producing 291 hp and 262 lb-ft, paired with an 8-speed automatic and available AWD. Bank 2 on this V6 is the rear cylinder bank (closest to the firewall). A P0175 code on a 2024 model is uncommon given the low mileage, but environmental factors and manufacturing variability can trigger it.
Symptoms
- Check engine light illuminated
- Fuel economy below the rated 20-26 MPG
- Subtle rough idle or vibration
- Dark exhaust deposits
- Reduced acceleration when loaded
- Faint fuel odor from exhaust
Causes on the 2024 Telluride
1. MAF Sensor Contamination (High Likelihood)
The most likely cause even on a new vehicle. The Telluride's large V6 draws high airflow through the MAF sensor, and exposure to dust, PCV oil vapor, or over-oiled aftermarket air filters can contaminate the sensor quickly. Given the Telluride's appeal to families who may take it on road trips through varied terrain, dusty environments accelerate sensor fouling. Clean with dedicated MAF sensor cleaner as the first step.
2. ECM Software Calibration (Medium Likelihood)
Kia regularly releases ECM calibration updates for current model year vehicles. A fuel trim calibration refinement may resolve P0175 without any parts being replaced. The dealer will check for applicable TSBs and install any available software updates as a free warranty repair.
3. Bank 2 O2 Sensor Manufacturing Defect (Medium Likelihood)
A manufacturing defect in the upstream wideband O2 sensor on Bank 2 can cause incorrect fuel trim feedback from the first day of operation. A sensor biased toward lean readings will cause the ECM to continuously enrich the mixture. This is a warranty-covered defect that the dealer can identify and replace at no cost.
4. GDI Injector Seal Defect (Low Likelihood)
The 3.8L GDI's high-pressure fuel injectors are precision components. Occasionally, an injector may ship with a minor seal defect, allowing fuel leakage when closed. On a new vehicle, this is a manufacturing defect covered under warranty. The dealer's injector balance test quickly identifies any problematic units.
Warranty Coverage
The 2024 Telluride has Kia's comprehensive warranty: 5-year/60,000-mile basic, 10-year/100,000-mile powertrain, 8-year/80,000-mile federal emissions. All P0175-related repairs are fully covered. Take the vehicle to a Kia dealer for no-cost diagnosis and repair. Do not attempt complex DIY repairs that could complicate warranty claims.
GDI Carbon Buildup at Low Mileage
While the 3.8L GDI is known for carbon buildup at higher mileage, a 2024 model with limited miles should not have significant carbon accumulation yet. Carbon cleaning is not typically warranted at this stage unless a borescope inspection reveals unexpected deposits. Focus on sensor and software causes first.
Diagnostic Approach
- Visit a Kia dealer for warranty diagnosis.
- Request TSB check and ECM software updates.
- If DIY, cleaning the MAF sensor is a safe first step.
- Dealer will test O2 sensors and fuel injectors as needed.
Costs (If Out of Warranty)
MAF cleaning: $10-$15. MAF replacement: $130-$300. ECM update: $100-$200. O2 sensor: $180-$370. GDI injector: $250-$480 each. Carbon cleaning: $500-$800. All covered under warranty for 2024 models.
