Consumer Description
Hello, I have a 2021 Honda Accord Sport 2.0T Engine. The engine has a 2.0 liter turbo. I have had to replace two fuel pumps, which were covered my extended warranty. Another issue that I had to repair, and one that has not fully been resolved is the head gasket. I have been losing coolant at an alarming rate. Every two weeks I have to fill up coolant. I had the head gasket repaired at a Honda Dealership, and this is currently being diagnosed by another Honda Dealership, as I do not want to deal with the Honda Dealership in Cedar Rapids, Iowa. Currently, a Honda Dealership in Iowa City, Iowa is handling the issue, but the head gasket along with the cylinder head were originally repaired in October 2025. Since December 2025, I have been losing coolant on a regular basis. I still have 5,000 miles left on my extended warranty, but there have been many owners who have had their head gasket replaced, or are needing replacement, and Honda refuses to acknowledge that there is a manufacturing defect with the engine. The 2.0 liter turbo engine has a major design flaw with it's cooling passages, and Honda has yet to come up with a resolution. Having an engine overheat is a major safety concern! The current dealership is driving my vehicle on a regular basis, in fact the service advisor is driving it to work and back home (35 miles each way) to replicate the problem. At this point, a recall should be issued by Honda, as there is currently a class action lawsuit that has occurred in the state of California.
