I leased this vehicle, brand new. I bought out the lease just over a year ago. The truck has under 113,000 miles. I drove the vehicle to New York for a trip. The motor started, knocking, ticking real bad so I pulled into the shop (Monroe) they looked at the engine and said it's blown. They was no waring/check engine light never came on. Gauges were fine (digital). It cost me 16 grand to put a new motor in and dodge will not cover it. The mechanic also stated, he sees these engine blown (V6) all the time in my RAM and in the Durango's.

1. Safety Issue 1: Cracked Exhaust Manifold & Exhaust Leak Description: Loud knocking noise on startup, strong exhaust fumes entering cabin. Dealer Diagnosis: Both exhaust manifolds cracked, multiple broken bolts. Risk: Potential carbon monoxide poisoning, engine damage, and fire hazard. Dealer Response: Refused repair, quoted $3,500. No assistance from Chrysler. Pattern Failure: Online forums show many owners with identical issues—clearly a manufacturing defect. 2. Safety Issue 2: Dashboard Delamination & Toxic Fumes Description: Dashboard surface peeling, strong chemical odor in cabin. Risk: Toxic off-gassing causes headaches/nausea; peeling material obstructs visibility. Pattern Failure: Widespread reports for this model/year—faulty adhesive is to blame. Manufacturer Negligence: Chrysler and dealerships are aware but refuse responsibility, blaming "wear and tear." Exhaust leaks and toxic interiors are unacceptable safety hazards—yet no recall exists. Request to the federal safety agency: Investigate these defects for potential recall. Force Chrysler to acknowledge and repair affected vehicles. Urgency: Driving this vehicle is a health risk. the federal safety agency must act before more are harmed.
