On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approximately 65 mph, these warnings had already been displayed for approximately 30 minutes to an hour when my vehicle suddenly began struggling to accelerate. Despite pressing the accelerator, the vehicle continued losing speed, and the RPM gauge remained around 2,000 RPM. It felt as though something was holding the vehicle back. After several moments, the vehicle suddenly regained power, accelerated, and the RPM increased. This was particularly concerning because I was traveling at highway speed.

Engine

39 reports3 crashes
“I am submitting this complaint regarding an ongoing safety concern with my 2021 Honda Accord. Multiple lights indicate engine system problems which includes, check engine light, car jerks at acceleration, seat sensor recall. I took my vehicle to multiple shops including the Honda Dealership. However, they were unsuccessful to identify the cause. Multiple problems such as Turbo, belt, fuel system problem constantly comes up. I have attempted to take my vehicle for the recall, which was scheduled, however after waiting 4hrs, the dealership stated they did not have the parts. I am concerned about the potential risk to myself, my daughter and my passengers and believe these issues warrant further investigation to help prevent possible accident or injury.”

Lane departure

16 reports
“Vehicle started flashing all lights on dashboard. I drove it for awhile and then it eventually went off. A few days later same lights came back on a car started misfiring. Was told by Honda that is was the Turbo that's going bad. Today is just cut off on me. Luckily there wasn't anyone behind me. I see a lot of people are having these same issues and a recall should be put out immediately.”
