2024 Honda CR-V Engine Problems

Throttle body replacement at only 23294 miles. Replaced under warranty . Did some searching and Honda is aware of coolant seeping into throttle body. This could cause failure while on road or hwy causing injury or death. This issue should have a priority permanent fix as my family is riding in this vehicle. This is unacceptable Thank You for your time into this report

Vehicle was purchased new on 5/17/2024. On January 16, 2026 the vehicle was brought into a Honda dealership because of 2 lingering issues. 1) It had low power while driving uphill on the freeway. When driving the vehicle from the Bay Area to Reno, the vehicle was unable to keep up with the flow of traffic travelling at the speed limit. Vehicles behind us were agitated. We did not know if this was normal or not and we wanted to have the car checked out. 2) The engine sounded different after the trip to Reno. Youtube videos, including some by Honda dealers had advised that the crv hybrid made noises which were considered normal. We wanted to know if the noise that we we're hearing was normal. The vehicle was in the shop for 26 days. The dealer confirmed the low power but had difficulty diagnosing the engine noise, except that it was not normal. The dealer brought in resources from Honda techline on multiple occasions to assist in diagnosis. During the course of the 26 days in the shop, the dealer ultimately found it necessary to rebuild the entire engine, including replacing the block, cylinder heads, lifters, fuel injector, etc.... We feel fortunate that we did not experience the more extreme loss of power and limp home mode that has been reported. We are very concerned about the future reliability of the vehicle. From the research that we have done, it appears that the primary cause of many of the engine failures experienced by this year/model are due to failure of the fuel injector system. What is really odd, is that the fuel injector system on our vehicle was inspected by the dealer on February 22, 2025, i.e., a year before we brought the vehicle in for the current issues.

On 12/6/24, while driving at highway speed, my engine made a LOUD EXPLOSIVE SOUND followed by immediate power loss—life-threatening. Vehicle couldn't exceed 65 mph despite full throttle, engine wouldn't idle, became inoperable. Had to merge right and limp to dealership in traffic. THIRD catastrophic failure in recent months at only 11,700 miles. First (10/19/24, 11,174 miles): Multi-system errors, inoperable, 21 days out. Complete cylinder head replacement (Cylinder 2). Second (12/2/24): Identical errors two weeks later. Cylinder 4 misfire, fuel injector replaced, 3 days out. Different cylinder proves systemic defect—50% of engine affected. Third (12/6/24): Highway breakdown. "Repaired" in hours with spark plugs only—inadequate for explosive failure. Service advisor admitted "whole part might have potential issue" but Honda policy prohibits preventive replacement "until really broken"—knowingly allowing defective vehicles until catastrophic failure. Dealership attempted release without highway test; conducted only after I demanded it. No explosive sound explanation. Refused diagnostics, compression testing, internal inspection. First two failures had dashboard warnings at low speed. Third had ZERO immediate warning—normal to explosive failure instantly at highway speed (warnings appeared 2 hours later). Unpredictable and extremely dangerous. Explosive sound indicates severe internal damage—not just spark plugs. Evidence: 11,700 miles too young. Specific cylinders (2, 4) suggest manufacturing defect. Dealership admitted defect. Immediate recurrence after major repairs. Vehicle at Parkway Honda (1575 VFW Pkwy, West Roxbury, MA), available for inspection. Honda case #16033311/12. MA AG/BBB complaints filed. 24+ days out. URGE NHTSA: Investigate if other 2024 CR-Vs affected, determine if recall needed, investigate Honda policy refusing repair until catastrophic failure.

I have a 2024 CRV hybrid Sport L. I recently had a warranty claim, that was attributed to an issue with the throttle body. The engine reduced power and would not go over 25mph. And emissions fault was announced, which forced the turning off of all safety features of the car. I was able to drive to the dealership during non-traffic hours. I don’t know if this could mid-drive , but mine fortunately happened when I turned the car on. I got the dealership to replace the throttle body and take pictures of the problem before and after. It appears that the EGR dumps downstream of the throttle body causing the butterfly valve “pin” to corrode and that tripped an emissions fault in my car and reduced the power and limited the engine to 25mph. The car only has 15k miles on it. The replacement throttle body has no redesign. It’s identical per the dealership and Honda. And no one is able to tell me if it’s going to happen again. I used the same exact gas as every other car I drive, and I have driven in the same city environment for 10 years now. So it’s clearly a design or quality issue. Honda would not give me more information. So I was forced to take this route.

Driving on an [XXX] near St Pauls NC at 70mph the engine shut off. Annunciator came on stop now engine is quitting. Check engine light came on. We were in a construction zone so there were barriers blocking the shoulders. We were in a high risk of someone behind ramming into us. We coasted to the exit which was 1/2 mile away. We exited at 2mph. We were very fortunate that no one from the rear, hit us. There was a tractor trailer behind us who put his flashers on, realizing the issue stayed behind us to keep cars from hitting us. All warning lights came on, first engine then all of the safety warnings. Car would not run. It was towed to a Honda dealer in Fayetteville. Honda analyzed the issue as a misfire resulting in engine damage. They performed a boroscope and found 3 piston cracked. Honda after 3 weeks installed a new short block and fuel injectors. Car was one year old with 6280 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

3 Check engine lights came on when my car was transitioning from electric to gas while I was sitting idle. I towed my brand new car (6500 miles) to the honda dealership and they diagnosed it as faulty fuel injectors, a bad spark plug, and a bad ignition coil. The dealer said this is a widespread issue and they have been servicing this type of issue very frequently.

It is making like diesel trucks sound with vibrations while accelerating the speed! Since few days.

I almost got into accident twice by using Auto Engine Stop/Start feature at traffic light. Traffic light was green and the car in front of me turned right but they were too slow to turn which I had to hit my break. Due to hitting my break, the car thought I was stop/idle so it turned Engine off. When the car turned Engine off, it basically got hiccups or stalls for few second and the car behind me almost hitting me as traffic light was green to go. You can only temporarily turn off this feature and it will default turn on when the car starts which will lead to accidents in matter of time if I forgot to turn it off every time I start the car. Honda should update software to allow customers to turn it off permanently if they want to instead default on.
