Real HONDA RIDGELINE Owner Reports (Source: NHTSA Complaints Database)

"Upon exiting or entering the highway, the truck loses power and will not accelerate. This happens after multiple hours of highway driving and seems to only happen when the temperature is near or below freezing. The Check Engine Light (CEL) comes on and is flashing."

"The CEL flashed 2 days earlier, I immediately pulled to the side of the road and turned the vehicle off, suspecting it may be a misfire. Restarted the vehicle and all seemed fine. After arriving home i plugged in my scanner to check for a code. No codes were found."

What To Do Next

  1. 1
    Check for recalls on YOUR VIN

    Go to nhtsa.gov/recalls and enter your VIN. Free repairs if your vehicle is covered.

  2. 2
    Get a proper diagnosis

    A code alone doesn't tell you the exact failed part. A diagnostic at a shop ($50-$150) pinpoints the root cause before you spend money on parts.

  3. 3
    Compare repair quotes

    Get 2-3 quotes. Dealer vs independent shop prices often differ 30-50% for the same repair.
