Causes of resonance noise in a sedan's roof: 1. Issues with manufacturer assembly: Possible insufficient assembly force leading to friction between components, or areas where welding has failed causing friction between steel plates; 2. Problems with certain parts: There may be unsecured items inside the roof; 3. Noise from door hinges; 4. Noise from sealing strips; 5. Noise from interior panels. Solutions for resonance noise in a sedan's roof: 1. Lubricate the panoramic sunroof sliding tracks; 2. Remove the roof to add sound insulation padding; 3. Reinforce the sunroof frame rivets. If replacing all necessary parts does not resolve the issue, it indicates a problem with the manufacturer's assembly. In such cases, there is no effective solution other than removing the roof and replacing the entire roof panel.

What is the highway fuel consumption of the Li ONE?

Actual test of the 2021 Li ONE model: cruising at 120km/h on the highway for 351 kilometers consumed 34.1L of fuel, resulting in a fuel consumption of 9.7L per 100 kilometers. For the 2019 BMW X5, owner-measured highway cruising at 120km/h showed a displayed fuel consumption of 8.5L/100km, with the actual consumption estimated at around 9L. The highway fuel consumption of the Li ONE is slightly higher than that of recent fuel-powered vehicles. The technically outdated range-extender hybrid system results in highway fuel consumption comparable to, or even higher than, that of fuel-powered vehicles. There is still a significant gap between domestic and Japanese hybrid technologies. For example, the Highlander hybrid actually has relatively low highway fuel consumption.

What does brake drum noise mean?

Brake drum noise refers to the abnormal sound generated by friction between the brake shoe and brake drum. When encountering this situation, simply disassemble the brake drum, remove the brake shoe, and clean any foreign objects between them to resolve the issue. If foreign materials are adhered to the brake shoe, use coarse sandpaper to grind them off until separated, then reinstall to solve the problem. If you notice that increased force is required for braking, immediately stop using the vehicle and visit an after-sales service or repair shop as soon as possible to replace the brake shoes. Continued use under such conditions may lead to dangerous situations. Generally, squealing from rear brakes is caused by water ingress, excessively smooth brake pads, or substandard brake pads. First remove the brake disc; if it appears too smooth, sand it with sandpaper or a flat file, and replace the brake pads if necessary.
