Why is the engine noise of the Hongqi HS5 getting louder?
2 Answers
The increasing engine noise in the Hongqi HS5 may indicate engine damage. Here is an introduction to Hongqi: 1. Introduction to Hongqi: Hongqi is a premium automotive brand directly operated by FAW. On January 8, 2018, FAW announced the new Hongqi brand strategy, with 'Chinese New Noble Delicacy' as its brand philosophy. On July 31, 2018, the 60th anniversary celebration of the Hongqi brand officially commenced. On October 23, 2018, Hongqi became the diamond partner of the 5th World Internet Conference. 2. Hongqi's service philosophy: Establishing the 'Hongqi Heart Service System,' which includes offline experience centers, digital experience centers, the Qishituan community, Hongqi shared mobility, and a lifetime free service commitment (warranty, rescue, pick-up and delivery).
I've been driving my Hongqi HS5 for over three years now. Initially, the engine sound was very quiet, but now it buzzes when accelerating, and the noise is getting louder. It's probably due to aged engine oil, where the reduced lubrication effect increases component friction; or it could be excessive carbon buildup causing uneven combustion and additional vibration noise; loose or worn belts can also cause noise. During my last maintenance visit, the technician mentioned that Hongqi engines are quite refined, and long-term neglect of oil changes or clogged air filters can easily lead to such issues. I think the loud noise is not just annoying but might also reduce performance and even affect fuel consumption. It's advisable to quickly check the oil color and viscosity and try changing it; if that doesn't help, have a professional inspect the belt tension and ignition system. Regular carbon cleaning for prevention is also important.
