Since April 2026 my Honda Crv 2021 had been having issues with all the warning lights on my dashboard turning on and off. When all the lights turn on the sensors don’t function the way they supposed to and won’t alert me when I’m getting close to a car or need to make a sudden break. I took it to Autozone to get the codes from the warning lights and also to Honda and both said that I needed to replace, the fuel injectors. I replaced the fuel injectors and the problem still there. It was inspected by Autozone, Honda and also an independent auto shop.

While driving on the highway with my child in the vehicle, all dashboard warning lights suddenly turned on at once. Immediately after, the vehicle began to shake, lose power, and would not accelerate properly. The vehicle was jerking and pulling back and forth, creating a dangerous situation in traffic. I took the vehicle to a mechanic, and they diagnosed a failure of the high-pressure fuel pump and all four spark plugs. The repair cost was $1,436. This failure happened unexpectedly in a 2021 Honda CR-V, which raises serious safety concerns due to sudden loss of power while driving at highway speeds.

CRV Dashboard all warning lights illuminated including check engine and emissions system problem. I had to park my car and it smelled like gas. I immediately called Honda Care and I took my car to Unicars Dealer on 03/11/2026 They provided a diagnostic report, report retrieved PO172 fuel system Bank 1 too rich and P219F no 4 cyclinder air fuel ratio variation. Despite Honda issuing Service Bulletin NHTDA ID 10220352, 10208090 and similar 22-002 for the exact same part failure 2017-2019 models, and despite Manufacturer Communication MC -10201454 specifically requesting failed injectors from 2021 models for investigation, HONDA HAS REFUSED TO PROVIDE A WARRANTY EXTENSION OR GOODWILL ASSISTANCE FOR THIS KNOWN DEFECT. This is a premature failure of critical fuel system component that causes the vehicle to stall smell like gas, lose power unexpectedly posing a significant safety risk to the driver and others on the road. I opened a GoodWill case # 16219868- after two weeks Case manager said it did not meet their guidelines offered a $125 assistance.

I finally walked into the UNICARS Dealer yesterday 3/25/26 and made appointment to get vehicle fixed on 03/27/26. I am paying out of pocket for all repairs over $2000 dollars.

While I was driving my engine installed and all of the lights on my dashboard lit up, including, but not limited to the check, engine, tire, pressure and disabling of all of my safety features. Once I had it towed to the Honda dealership, I was told my fuel pump was not working. As I was on the interstate, my car stalling was absolutely a risk for a collision. When I asked the technician what could’ve caused this problem he said “I’m not sure but we’ve had a few of these recently.” so I feel like it has been reproduced. Prior to the failure, there was no sign of issue. I recently (August 15th) had my car serviced for an oil change and there were no issues.

My check engine light came on while driving, stating a system emission problem. 24 hours later, all driver-assist safety features have warning lights on the dash that all systems were disabled. I brought my CRV to Honda dealership service dept who determined that my fuel injectors had failed and needed replaced. Once the injectors were replaced, all the dash warning lights shut off and driver assist programs are working again. My car is only 3 years old and has 71,000 miles on it, and is outside of the parameters for the original warranty provided by Honda. I believe the fuel injectors should be recalled because of how many 5th generation CRVs need fuel injectors replaced during the early life of the car.

Took my Honda CRV 2021 EX in because all of my warning lights (Critical Failure) were going off as I was driving. All safety features were failing including AWD control, braking, sensors, cruise control, etc. They replaced the battery and tested the alternator. They reset the system and said it was fixed. I picked mine up today, drove it for 10 mins on the highway and then hit the "MAIN" button on the stearing wheel to turn on the cruise control. As soon as I did that, ALL of the warning lights came on at the same time and the systems started to fail again. This is a hazard and could cause an accident at any moment. In reviewing the Honda forums, this is a massive problem with hundreds of Honda CRV EX 2020-2022 models. I'm 7000 miles over my warrant and Honda won't look at it. However, it is directly their problem and my car is only 2 years old.
