Complaint Summary

ENGINE

Owner Narrative

During highway driving, alert on dashboard stated “electrical system failing enter idle mode”. Tahoe slowed down and then engine began knocking right as it shut off resulting in needing to coast to the shoulder of the highway safely since engine was off. Towed to dealership and then they came back saying needed a new battery, new alternator belt, pulley and water compartment. After those installed, additional call was made indicating the engine needed a full replacement as it keeps overheating despite no sensor alerts and codes are being tripped. Here we are asked to pay 16K for new engine install and unable to fix.
