2018 Chevrolet Equinox: Model Year Overview
The 2018 Chevrolet Equinox launched the third generation with all-new turbocharged 1.5T and 2.0T Ecotec engines replacing the older 2.4L naturally aspirated four-cylinder. By 2026, with approximately 105,000–135,000 miles, these turbocharged engines are entering the window where timing chain wear and oil consumption become significant repair risks — especially when maintenance intervals have been stretched.
Known Issues on the 2018 Chevrolet Equinox
1.5T Ecotec Timing Chain Stretch
Timing chain stretch on the 1.5T Ecotec engine is the most commonly reported mechanical issue on the 2018 Chevrolet Equinox. Owners report costs of $1,500–$3,200 for full timing chain replacement. Rattling on cold starts and a check engine light with camshaft position codes are early warning signs.
Consumer Reports and NHTSA owner complaint records identify timing chain stretch and oil consumption as the leading unplanned repair costs on 2018 Chevrolet Equinox models with 1.5T Ecotec engines — a repair that routinely exceeds $2,000 at dealer rates.
9-Speed Automatic Transmission
The 9-speed automatic transmission on the 2018 Equinox has documented complaints of shudder, hesitation at low speeds, and delayed engagement. Transmission repair or replacement typically costs $2,500–$5,000 at an independent shop.
