2025 Chevrolet Suburban Lemon Law Case Study: New Jersey

A 2025 Chevrolet Suburban With Check Engine Light, Rough Running, and Cylinder #4 Misfire

Our client purchased a 2025 Chevrolet Suburban in New Jersey (Aug 2025). Documented service history describes an intermittent check engine light and rough running, a misfire in cylinder #4 with diagnostic trouble code P0304 and an intermittent no spark condition (leading to #4 ignition coil and later #4 fuel injector replacement), and a later EVAP concern where code P0455 was tied to a purge solenoid that was not pulling vacuum and was full of fuel, as was the canister. Current mileage on the odometer: 17,000. Intake indicated the vehicle was not in the repair shop for more than 30 days at any time. The client contacted Easy Lemon for legal assistance under the lemon law.

Service notes record that “The customer reported that the check engine light was intermittently turning on and off and the vehicle was running rough.” Further: “The customer returned with the check engine light on and reported a misfire in cylinder #4. Diagnosis revealed diagnostic trouble code P0304 and intermittent no spark condition, though all circuits tested okay. The #4 ignition coil was replaced and the repair was completed.” Technicians then documented that “Diagnosis again found code P0304, and while circuits tested okay, the fuel injector balance test failed on cylinder #4. The #4 fuel injector was replaced and the repair was completed.” And: “Testing of the EVAP system seal revealed the purge solenoid was not pulling vacuum and was full of fuel, as was the canister. The canister and purge solenoid were replaced, and the system tested okay after repair.”

What Went Wrong

• Intermittent check engine light / rough running: the check engine light was intermittently turning on and off and the vehicle was running rough.
• Cylinder #4 misfire (P0304): a misfire in cylinder #4; diagnosis revealed diagnostic trouble code P0304 and intermittent no spark condition; the #4 ignition coil was replaced.
• Cylinder #4 fuel injector: diagnosis again found code P0304; the fuel injector balance test failed on cylinder #4; the #4 fuel injector was replaced.
• EVAP / P0455: diagnosis found code P0455; testing of the EVAP system seal revealed the purge solenoid was not pulling vacuum and was full of fuel, as was the canister; the canister and purge solenoid were replaced.
• Repeated return visits: the customer returned referencing previous visits as the check engine light and related concerns recurred across September 2025 through March 2026 service dates.
