The engine cooling system failed due to a coolant loss issue caused by an internal engine problem. The vehicle experienced repeated coolant loss, overheating, and was later diagnosed with a head gasket failure. The failed components were repaired/replaced by an Acura dealer and may be available for inspection upon request through repair records and replaced parts if retained. The failure created a safety risk because the vehicle overheated while driving and while idling in traffic. Loss of coolant and engine overheating could result in sudden loss of vehicle power, engine damage, or a breakdown in unsafe locations such as roadways. The issue was especially concerning because the symptoms occurred without an immediate warning that allowed enough time to safely prevent the failure. Yes. The coolant loss and overheating concern was confirmed by service providers. An Acura dealer mechanic performed testing that indicated combustion gases were present in the cooling system.

Completed 100,000-mile service work at the dealership, 1 month following the work, while driving, all engine codes went off and the car went into "limp mode". I was unable to drive at normal speeds while on a major highway and going through a busy intersection. After multiple assessments at the same dealership, a "software update", a replaced spark plug (that was previously replaced during service work a month prior), it was found to have a warped head gasket with coolant leaking into the engine. It has not been inspected by police or insurance agents. It has been inspected by Shottenkirk Acura of Huntsville (Alabama) and a secondary mechanic with the same findings of engine failure. This should not occur at 116,000 miles in a Honda motor!
