Ownership of the 2018 Ford Explorer brings a sense of spacious utility and American automotive confidence, yet even this robust SUV is not immune to the wear and tear of modern driving. While the model year addressed many reliability concerns from its predecessors, specific 2018 Ford Explorer problems emerged that demanded attention from both owners and technicians. Understanding these issues is the first step in ensuring your vehicle remains a dependable workhorse rather than a source of constant frustration.
Common Mechanical and Electrical Issues
The 2018 model year saw the Explorer evolve, but it also inherited and refined some of the gremlins that plagued earlier generations. One of the most frequently reported issues involves the automatic transmission, specifically with the 10-speed torque converter used in the EcoBoost variants. Drivers noted harsh shifting, particularly during low-speed maneuvers, which detracted from the smooth ride the vehicle promised. Furthermore, the transition to a smaller, forced-induction engine introduced concerns regarding premature timing chain wear, a critical component that if neglected, can lead to catastrophic engine failure and costly repairs.
Electrical System Glitches
Modern vehicles are rolling computers, and the 2018 Explorer is no exception. Owners have documented a range of electrical gremlins that can turn a daily drive into a diagnostic puzzle. These include malfunctioning infotainment systems that freeze or fail to recognize USB devices, as well as issues with the park assist camera displaying incorrect guidelines or failing to activate entirely. Perhaps more concerning are reports of random warning lights illuminating on the dashboard, such as the stability control or check engine light, which can indicate a variety of underlying sensor faults.
Focus on the "Coughing" Explorer Recall
Perhaps the most significant event defining the reliability narrative of the 2018 Ford Explorer was the manufacturer recall concerning the 3.5-liter EcoBoost engine. This initiative, widely publicized by the NHTSA, addressed a serious issue where the engine could "cough," stall, or, in worst-case scenarios, catch fire due to a risk of hydrolock. The problem stemmed from coolant mixing with engine oil under specific cold-start conditions, creating a sludge that blocked the cylinders. If you own this model year, verifying the repair completion is not just recommended; it is a critical safety imperative.
Addressing Suspension and Component Wear
Over time, the 2018 Ford Explorer’s suspension components, specifically the front lower control arms and ball joints, have been flagged as areas of potential weakness. Some drivers have experienced a clunking noise over uneven road surfaces or a noticeable drift in alignment, suggesting that the robust towing vehicle design might be compromised by material fatigue. Ignoring these sounds can lead to uneven tire wear and a less stable platform, which is particularly dangerous in adverse weather conditions.
