2021 Honda Civic Type R problems

Filed Oct 28, 2026 · Engine · TX

I recently discovered that coolant has been leaking into two of my cylinders, causing an overheating issue. The Honda dealership tells me this is a known issue for their engines for that year range, so much so that an extended warranty has been added to all other engines but there is a carve out for the Type-R. The same damage is occurring and they know about it but they are failing to address it. I am a lawyer and I will also be working on putting together other owners to certify a class if this route is not successful. I first became aware of it based on a rev match error and an emissions system error being thrown at the same time, and then the engine started to overheat when it was started from cold. I could get the engine temperature to come down by manually engaging the air conditioning. This was some type of cooling system error as well, but I didn't see that on the checklist above. The dealership has confirmed the error and reproduced it. It is currently still at the dealer and is available for inspection.

While operating my 2021 Honda Civic Type R (VIN: [XXX] ) in high-ambient temperatures (approximately 95°F), the vehicle experienced a sudden and total loss of motive power during acceleration while exiting a busy intersection. This resulted in an immediate engine stall in the path of oncoming traffic, creating a severe risk of a collision. Following the stall, the vehicle was extremely difficult to restart. Once restarted, it entered a 'limp home' mode with a severely restricted RPM limit and multiple dashboard warnings, including 'Emissions System Problem' and 'Rev Match System Problem.' A diagnostic scan performed immediately after the incident revealed a DTC P0087 (Fuel Rail/System Pressure - Too Low). The symptoms—thermal-related failure, stalling under load, and the P0087 code—are identical to the documented mechanical failures of the Denso fuel pump impeller swelling defect. Although this production year and model are known to be part of the expanded fuel pump recall population, my specific VIN is not currently showing as 'remedied' or 'open' in the manufacturer's database. I am reporting this as an active, unaddressed safety defect that poses an unreasonable risk of crash or injury due to unpredictable engine failure in traffic.

Car abruptly shut off after start up. Then car started and ran normally for 2 days. Then after start up CEL came on for emissions problem. Took to dealership and said it had a P0546 (small evap leak) code. Performed a leak down test and no leak was found. Then said fuel was present in charcoal canister. These are same issues and complaints that other Honda owners have had about vehicles that fall under the fuel pump recall. My car is a 2021, but was built late 2020. Vin # is right at the end of recall vins. I want to report my issue just in case my fuel pump goes bad while driving and causes an accident.
