2023 Honda RidgelineRecalls, problems, MPG & safety

“The auto-dimmer function does not work. On high-beam there is no automatic dimming; on low-beam the high beam automatically and randomly flashes on for a couple seconds, then off. In the latter instance, oncoming traffic gets hit with a sudden blinding flash - creating a hazard. My understanding is that this has been a problem for several years even before we bought the vehicle new and the company misled us into believing the function was available on the vehicle. The company also simply ignoring and not trying to fix it. Given the false advertisement of the functionality in the vehicle and hazard to oncoming traffic when it is on, one might reasonably expect a recall to be issued.”

“Auto shut off and restart will shut the engine off at a red light or intersection but then it tries to restart but the stalls the engine. I have to shift it quickly into park and restart the engine with several cars behind me. This is a safety hazard. This has happened multiple times. Honda says that this isn’t covered under the 10 year extended warranty unlimited miles for this problem with the 2023. Ridgeline.”

“My 2023 Honda Ridgeline (about 28,400 miles) repeatedly loses power while driving. The instrument cluster lights up with every warning light at once, the truck stops accelerating, and I cannot maintain speed. It has happened on the freeway above about 60 mph, which is extremely dangerous with surrounding traffic moving at highway speed. Disconnecting the battery for about 15 minutes temporarily clears the warning lights and lets the truck move again, but the problem keeps returning. I have taken the vehicle to a Honda dealer three times for this same problem: July 2026, late August 2026, and October 2026. At the August visit, the dealer scanned the vehicle and found multiple lost-communication codes and DTC U0401 (invalid data received from PCM). The powertrain control module (PCM) was replaced under warranty and relearn procedures were performed. The problem returned after the replacement, and the truck is again at the dealer for diagnosis. I have video recordings of the failures and repair records for all three visits. I am concerned this is a defect in the powertrain control or vehicle communication system that can cause a sudden loss of power at highway…”
