Model: 2021 Honda CR-V Hybrid VIN: [7FART6H80ME003035]] Mileage: [78000 old motor | 25000 replaced motor] Issue Type: Engine Stalling / Rough Idle/ Low Operating Temperature / Warranty Denial Maintenance History: Dealer-maintained per schedule Dealer Name/Location: [American Honda Motor Co., Inc. Attn: Customer Relations / Warranty Department 1919 Torrance Blvd. Torrance, CA 90501] Manufacturer Contacted: Yes -?" denied assistance despite known issue TSB References (if applicable): TSB 21-013, TSB 22-087 --- Complaint Summary: I am reporting a known issue with my 2021 Honda CR-V Hybrid involving engine sludge accumulation and chronically low operating temperatures, which I believe are tied to a systemic design flaw affecting hybrid models of this generation. Despite proper maintenance at a Honda dealership, I was informed of internal engine sludge. The issue appears linked to the engine not reaching optimal operating temperatures-?"leading to oil degradation and sludge formation over time. This matches problems detailed in official Honda Technical Service Bulletins (TSB 21-013 and TSB 22-087), yet I was denied warranty support, even under a Goodwill request. Honda regional representatives and mechanics provided no meaningful analysis or assistance and defaulted to denying support without adequately addressing the root cause. This is deeply concerning, particularly since multiple owners nationwide have reported similar problems. I believe this issue poses a long-term reliability and potential safety risk and should be investigated. I seek resolution from Honda, including coverage of necessary repairs and full acknowledgment of the defect.

I am experiencing the problems that are described in investigation NHTSA CAMPAIGN NUMBER: PE25016. When driving on the highway, there have been multiple times (8-10) when the car stops accelerating and the check engine light starts flashing. I am not able to accelerate the car. If it turn the car off for 5-10 minutes, the check engine light stops flashing and I am able to drive the car again. It has always happened when I haven't driven the car for a while (either driving it for the first time for the day or after sitting idle at work for 8 hours), the problem happens within minutes of getting on the highway. I have taken the car to the dealership for service twice with this problem. The first time was in late August. They said there was no code with the check engine light and they could not replicate or find a problem. The most recent time was this past Friday (Nov. 21, 2025). I experienced the problem and immediately took it to the dealership. Because the check engine light was flashing, they were able to pull diagnostics and retrieve a code. They said a fuel check showed cloudy fuel and a spark plug was brown to copper color. They removed the old fuel and replaced all four spark plugs. This did not fix the problem, as I experienced it again this morning (Sunday, Nov. 23).

On 7/21/2025, the car smelled of rotten eggs. When I got home I checked the Honda website for recalls. There is a recall on the fuel pump for my type of car, but not with my vin number. I researched that if the fuel pump goes without repair it can lead to the catalytic converter needing replaced. So, I went outside to go get some dinner and the car wouldn't start. Everything inside flashed a few times and then went dead. This car is only 4 years old. I believe they've missed my car on their recall list.

Head gasket failure. 79,600 miles. Car consumes coolant. Coolant is entering the firing ring when car sits after being driven a distance of 5 miles or more and sits for about 8 hours, vehicle starts with a misfire and makes a small amount of white sweet smoke out of the exhaust pipes even in 85 degree weather. Car smooths itself out after 10-30 seconds. No OBDII or Honda specific codes. Spark plugs, ignition coils, and spark plugs again since 75K. Over $2,000 into this car in repairs. Refilled coolant reservoir 3 times since April 8TH (3 full jugs of Peak Asian blue from Advanced Auto Parts). I want justice for this car and other Honda 1.5T vehicle owners as many of them have this happen at the 80K mark and they-??re being quoted $10K for an engine and $5K for a head gasket. There are several people with Accords, Civics, CR-Vs equipped with the 1.5T engine that have coolant leaking into one cylinder. Oil looks fine and not milky. And besides the coolant being low, it looks fine (blue/aqua). Only when the car sits. Car was brought to Rivera Honda in Port Jeff and they couldn-??t find any issues. Car is consuming coolant. No leaks. It-??s being burned when you start the car after it sits. Gushing liquid noise when car starts or with idle engine stop activated and car restarts.Design flaws on cylinder head has grooves that allow coolant to flow on top of the head to cool it. Failure point according to a Honda mechanic on YouTube. Second flaw is poorly designed head bolts that are too thin and are brittle, not making a good seal as the vehicle ages. Parts are not expensive at all, but the man hours needed to replace this are the killer. 4.5 years old with 80K, it-??s Honda. It-??s supposed to run forever. Not die under 100K. I would expect this problem after 250K or when the car is over 10 years old. My Godmother had a 1998 Accord that she had for over 20 years and it only needed a fuel pump as a major repair. A testament to Honda-??s rock solid reliability. What happened?

I drove to Pittsburgh on [XXX]. I got back in the car, pulled down the driveway and when I tried to enter traffic the car lost power, the dashboard went crazy with error messages and the car was useless. Had it towed to the nearest Honda dealer, they suspected fuel. The high pressure fuel pump was the part that fixed the problem. Fault code dtcp0087 was found in the ECU. I obtained a fuel sample and had it checked, the water content was a little out of spec but nothing really bad. I do have the fuel pump in case anyone wants to do a failure analysis. To add insult to injury, my extended "warranty" is refusing to cover the repair because they just want to say no. [XXX]... The bill was $1786.11, not including a rental car and my time. I have heard of quite a few recalls on these Hondas, you might want to add my model year to that list. Please advise if you have had other reports. Thanks!

2 MONTHS AFTER PURCHASE I have a lemon with Honda CR-V year of car 2021 bought it in October of 2021. The 3-year warranty is about to expire. I have taken the car several times to two different Honda dealerships because they are the closest to my home and I don't have anyone to pick me up or take me back. They claim there's nothing wrong with the vehicle but lights in the dash come up every other day then disappear after several hours then return the next time, I use the vehicle. the vehicle also has an issue with the acceleration; sometimes I step on the gas pedal but after trying to drive the car, the MOTOR does NOT move faster but rather the force of the vehicle decreases and doesn't allow for me to go faster than 20 MPH. The odometer is also inaccurate; one month after driving the vehicle about 80 miles-the vehicle odometer increased around 10 miles. I only have about 9,877 miles that I-??ve driven the car-?? I'M [XXX] and cannot drive and take pictures while I'm driving. I barely know how to use my phone. I get nervous, start to panic and my heart starts racing and I feel like I'm going to crash. I'm scared for my life and my grandchildren that I pick up after school and take them to their home. ive tried to upload documents but i keep getting an error...INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
