2022 Honda Accord: engine overheating

Filed Oct 9, 2026 · Electrical · OH

The infotainment system glitches and will not respond to touch or will have phantom “touches” where the system will make inputs on its own. This is worse when it’s really hot and was told by dealership that this is due to components overheating and malfunctioning, and it requires the full system to be replaced. This can be a major safety issue when driving the vehicle.

I am submitting this complaint regarding an apparent head gasket failure involving my 2022 Honda Accord Sport 1.5T equipped with Honda's 1.5-liter turbocharged engine. At approximately 143,000 miles, I began experiencing coolant loss without any visible external leak. I also noticed rough operation and shaking during startup. Concerned about the symptoms, I consulted a Honda specialist who advised that the vehicle is exhibiting signs consistent with a failing head gasket and will likely require head gasket replacement. This vehicle has been meticulously maintained and serviced throughout ownership. I retain maintenance records and have taken exceptional care of the vehicle. There has been no abuse, neglect, overheating event, or failure to maintain the vehicle. Through my research, I have found numerous reports from owners of Honda vehicles equipped with the 1.5-liter turbocharged engine describing similar symptoms, including coolant loss, startup misfires, rough cold starts, coolant intrusion into cylinders, and premature head gasket failures. The consistency of these reports suggests a possible design or manufacturing defect affecting the durability of the engine. A failing head gasket can lead to loss of engine power, engine damage, misfires, overheating, and potentially unsafe driving conditions. Given the volume of owner complaints involving Honda's 1.5-liter turbocharged engines, I request that the federal safety agency investigate whether a safety-related defect exists and whether corrective action, including a recall or service campaign, is warranted.

Cracked cylinder head coolant leak from bad head gasket known issues through multiple owners

Filed Jan 23, 2026 · Engine · MI

The engine cylinder head developed a crack causing coolant leak, causing the coolant system to lose fluid. The leak originated from a hairline crack in the cylinder head, which has been confirmed by an independent, certified mechanic. The vehicle remained drivable initially, but a loss of coolant could lead to engine overheating, and catch on fire or smoke creating a potential safety hazard for the driver and others on the road. The vehicle was inspected at an authorized dealership at the direction of the manufacturer, which performed a teardown to diagnose the issue. After this inspection, additional engine components (timing chain and head gasket) were identified as damaged, though these failures were not present prior to the teardown. Other users facing similar leak issues were treated the same by dealership blaming other component issue and disregarding the visible crack. This defect appears to affect multiple vehicles of the same engine, as reported by other owners nationwide. Warning signs included coolant loss, which could escalate into a larger safety risk if not addressed. I have attached few user complains but if needed I can provide lot more user complaints around the nation as it is never ending.

Car started overheating randomly while driving and pulled over to see why. Opened the hood to white smoke everywhere and an active leak of coolant by the exhaust manifold. Took it to a mechanic and was told the cylinder head itself has porosity and/or a hairline crack. Pressure tested as well and can visibly see the leak coming from the cylinder head itself.
