Toyota Highlander engine rattles during acceleration on Toyota Highlander

Some Toyota Highlander owners report experiencing engine rattling during acceleration, which could be attributed to several potential causes. Commonly, the exhaust system may create sounds that are mistaken for an internal engine rattle. Additionally, issues such as rod knock, bad engine mounts, or a faulty torque converter could also contribute to the rattling noise. Some owners have identified drivetrain problems, including issues with the transmission, axles, or driveshaft, leading to unusual noises during acceleration. To resolve these concerns, it is advisable for owners to have the exhaust system inspected, check for rod knock or engine mount issues, and evaluate drivetrain components for wear or damage. If the rattling persists or worsens, consulting with a qualified mechanic or dealership for a thorough diagnosis is recommended.
