NHTSA complaint #11549862

Owner complaint summary

2019 Honda Civic Si (1.5L turbo engine with 6-speed manual transmission) purchased in September 2019 at CPO with 7,000 miles — current mileage 26,638. Honda factory CPO powertrain warranty valid until 11 June 2026 or 100K miles. If the vehicle is parked in gear (either 1st or Rerverse) without applying parking brake on even the slightest grade (uphill or downhill), the vehicle will slowly creep — on a couple of occurrences, the vehicle moved more than 6 feet. This has happened on multiple occasions as I do not always remember to manually apply the parking brake. Once while waiting for a friend to pick up a prescription at a pharmacy, I actually witnessed a "ratchet" effect movement of the vehicle in the parking lot while sitting in the driver's seat. I took the vehicle to Mohawk Honda (Scotia NY) for assessment. My answer was to always set parking brake as documented in owner manual — interestingly, it states the same for vehicles with CVT (automatic) transmissions as opposed to simply putting them in Park. I have owned literally dozens of manual transmission vehicles since 1981, and I have never before experienced this. Service manager (via phone) later blamed low compression engine as incapable of holding vehicle when in gear. Call to Honda Customer Service at the time referred me back to a dealer. I decided to pursue this once again after reading of another manufacturer's recall of a car that would not hold in place while parked.
