Quick answer

Engine Overheating Customer Complaint/Technician Observation: Customer complaint may include engine overheating. Discussion: When dealing with a customer complaint of engine overheating, it is most important to understand exactly what the customers definition is of overheating. An explanation from the customer of what exactly happened is necessary. Overheating descriptions could include warning lamp(s), messages in the cluster, steam/smoke coming from under the hood, gauge running higher than normal, actual engine temperature higher than what the customer considers normal, smells hot, coolant leaking under the vehicle, etc. Observed engine operating temperatures of 245 F (118 C) degrees or lower are typical and are NOT considered overheating.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
