Do new cars still require a break-in period nowadays?

New cars still require a break-in period, which typically lasts for 3 months or approximately 3,000 to 5,000 kilometers. Precautions to take during the break-in period of a new car include: 1. Warm up before starting: Turn the key to the second position and wait for 5 to 10 seconds before starting the engine to protect the new car's engine; 2. Avoid emergency braking: Emergency braking can shock the braking system during the break-in period, increasing the impact load on the chassis and engine; 3. Avoid overloading: Running a new car at full capacity during the break-in period can damage mechanical components; 4. Avoid long-distance trips: Taking long-distance trips during the break-in period increases the continuous working time of the engine, which can easily lead to mechanical wear.

I've been driving for over 20 years, and modern cars still have a break-in period concept, though the requirements are much more relaxed now. In the past, we were careful for the first 3,000 kilometers, but now many manufacturers' manuals suggest paying attention only for the first 1,000 kilometers. The key is to avoid slamming the accelerator or brakes right away and to keep engine RPM within a reasonable range. Last week, a friend picked up a new car, and the salesperson specifically advised against long highway trips or fully loaded steep climbs for the first 500 kilometers. Of course, with today's advanced manufacturing, engines undergo cold break-in at the factory, but letting metal components naturally settle is always beneficial. Just remember the first oil change milestone—no need to stress too much beyond that. Drive normally with slightly gentler habits, and the car will feel smoother after two or three months.

As a car enthusiast who frequently attends car club gatherings, I've noticed that the break-in period always troubles beginners. Nowadays, automakers generally consider the first 1,500 kilometers as the break-in period, with requirements summarized as three dos and three don'ts: maintain steady speeds, ensure all engine gears are properly run-in, and pay attention to the first maintenance mileage; avoid prolonged high RPMs, sudden aggressive acceleration, and towing heavy loads. Last month when test-driving a new SUV, the engineer mentioned that modern piston ring coating technology has reduced break-in requirements by over 60%. However, they still recommend avoiding launch starts, especially in turbocharged vehicles. City commuting is completely fine, just remember not to overload when going mountain driving on weekends. Actually, just driving normally for a few months will naturally complete the break-in process.

Our workshop frequently handles the first maintenance for new cars, and Hyundai vehicles still require a break-in period. Although the engine undergoes cold running-in before leaving the factory, components such as transmission gears and brake discs still need an adaptive break-in of 300-500 kilometers during actual driving. It is recommended to avoid two extreme driving conditions in the first month: continuous high-speed cruising for more than two hours and frequent stop-and-go traffic in congested areas. One customer drove on mountain roads on the day of pickup, resulting in premature wear and noise from the brake pads. It's best to vary the speed and RPM frequently during the first few fuel refills. With today's high precision in metal processing, deliberate break-in is unnecessary, but excessively aggressive driving will certainly harm the vehicle.
