What are the current issues with the 10th generation Accord?

Here are the specific issues with the 10th generation Accord: 1. Low ground clearance: The 10th generation Accord has an unladen ground clearance of 12cm and a laden clearance of 10cm, making it suitable only for paved roads. When encountering rough roads, scraping the undercarriage is unavoidable. It is recommended to install an engine guard. 2. Poor sound insulation: Wind noise, tire noise, and engine noise during rapid acceleration are all very loud, forcing drivers to turn up the audio to mask the noise. 3. Low configuration: The 7-inch central control screen is not touch-sensitive and lacks a car infotainment system, limiting usage to Bluetooth connections for listening to the radio. Additionally, the car has only four speakers with poor sound quality, and the halogen high-beam headlights provide mediocre illumination, which is noticeably insufficient for nighttime highway driving.
