NHTSA Complaint #11695176 — 2018 JEEP WRANGLER

The Check Engine light illuminated and diagnostic code P219A was recorded (Bank 1 Air/Fuel Ratio Imbalance), and the engine has a ticking noise. The dealership has indicated the issue likely involves the valvetrain/rocker arms/lifters and will require engine internal repair (valve cover removal, spark plug replacement, possible rocker arm replacement) estimated at ~$2,900-$4,500. The 3.6 L Pentastar engine has been the subject of numerous owner complaints of ticking noise, power loss, misfire, and premature valvetrain failure. I understand there have been related Jeep Technical Service Bulletins (such as 09-002-14 and 09-008-18) addressing these types of failures. A class action lawsuit (Maugain et al. v. FCA US LLC) alleges defects in the 3.6L Pentastar engine’s valve train (rocker arms, lifters) and failure to disclose the defect. Maintenance History: Regular oil changes (every <6,000 miles) at approved service centers; no prior major engine internal repairs. Concern: The defect affects engine performance, may lead to catastrophic engine failure, and potentially reduces safe vehicle operation and control (power loss, hesitation). Relief Sought: I request the NHTSA open a vehicle safety defect investigation and compel FCA / Chrysler / Jeep to evaluate this condition under recall criteria.
