We use OEM parts and follow manufacturer procedures so any reset preserves warranty eligibility and vehicle reliability. Choosing our dealership ensures transparency—every repair estimate clearly shows parts, labor, and the long-term savings of correct repairs versus repeated DIY fixes.

2021 Jeep Compass Check Engine Light Codes

Common check engine light codes for a 2021 Jeep Compass include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/system too lean), P0300 series (misfires), and P0455 (evaporative system leak). Left unaddressed, a P0420 can lead to failed emissions tests and damaged catalytic converters that cost hundreds to replace; P0171/P0174 reduce fuel economy and can accelerate component wear; persistent misfires (P0300 series) risk engine damage; and an EVAP leak like P0455 can indicate failed hoses or canisters that degrade performance and efficiency. At Larry H. Miller Chrysler Jeep Dodge Ram Albuquerque in Albuquerque, NM, our certified technicians diagnose codes accurately, explain repair options, and use genuine OEM parts to restore factory performance. We emphasize cost transparency and the long-term savings of addressing problems promptly—this lowers overall ownership costs and protects resale value.
