P0441 on Your 2024 Acura MDX: A Warranty Fix
Your 2024 Acura MDX — the three-row luxury SUV with the 3.5L V6 (290 hp) or Type S 3.0L turbo V6 (355 hp) and SH-AWD — has triggered P0441 for incorrect EVAP purge flow. On a brand-new luxury SUV, this is a warranty repair. Honda/Acura EVAP systems are generally reliable, so P0441 points to a specific defect or software need.
Symptoms You Might Notice
- Steady check engine light
- Normal V6 power and SH-AWD operation
- All luxury features working
- Possible subtle fuel smell
Common Causes on a New MDX
1. Bypass Solenoid Valve Defect
A factory-defective bypass solenoid valve (Honda/Acura's purge valve) that doesn't actuate properly. The Type S turbo model adds boost pressure complexity.
2. PCM Software Update
Honda/Acura releases calibration updates. Your dealer can check using Honda HDS and apply any available EVAP monitor refinements.
3. Canister Vent Shut Valve
A factory-defective vent valve that doesn't seal during EVAP self-tests.
4. Assembly Connection
An EVAP hose connection not fully seated during manufacturing.
What to Expect at the Dealer
- Bring your MDX to Acura — warranty repair
- Honda HDS diagnostic scan and TSB check
- Software update or component replacement
- Verification drive
Repair Cost Breakdown
- Under Acura warranty: $0
- Bypass solenoid (if out of warranty): $150 – $320
- Software update (if out of warranty): $100 – $175
Can I Drive With P0441?
Yes. Your MDX is fully functional — V6 power, SH-AWD, and all three-row luxury features work perfectly.
DIY vs Professional
Take it to the Acura dealer. Your 2024 MDX is covered under Acura's 4-year/50,000-mile warranty and 6-year/70,000-mile powertrain warranty. EVAP qualifies for federal emissions warranty (8 years/80,000 miles).
