Whether a car develops problems depends on later maintenance. Here are the specific details about car maintenance: 1. Main items: Replace engine oil and oil filter, air filter, fuel filter, transmission fluid, and tire maintenance. 2. Purpose: The goal of car maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. 3. Importance: Daily car maintenance is very important. Neglecting routine maintenance can not only cause unnecessary damage to the vehicle, shortening its lifespan, but also endanger driving safety.

I've been driving a Buick for eight years now. In the first few years, it ran really smoothly with no major issues, but problems started popping up around the fifth or sixth year. First, the AC vents sometimes wouldn't blow cold air, and an inspection revealed it was due to compressor aging. Later, the engine warning light came on, and it took replacing several sensors to fix it. These malfunctions were mainly related to natural wear and tear of components as the car aged, especially with high mileage where the drivetrain and electronic components are most prone to issues. Overall, Buick has good reliability – after all, it's an American brand known for being sturdy and durable. However, after five years of ownership, I recommend getting a full vehicle inspection every six months, with special attention paid to transmission fluid and electrical connectors. This can significantly extend the car's lifespan and prevent breakdowns on the road.

As someone who helps out at an auto repair shop, I've seen too many Buicks that are seven or eight years old come in for repairs. Common issues include power steering pump leaks, engine belt noises, and occasional electronic control unit failures, which are quite prevalent in high-mileage vehicles. The failure rate tends to be higher between six to ten years due to aging rubber seals causing fluid leaks or circuit board oxidation leading to poor contact. Buick's engine and chassis designs are actually quite reliable, but problems can easily arise if owners neglect regular maintenance. I recommend not waiting until after 100,000 kilometers for a major overhaul. Regularly changing the oil and cleaning the throttle body can effectively prevent these troubles, ensuring the car runs longer and more reliably.

Friends considering buying a Buick should note that it generally remains reliable for about five years, but the risk of malfunctions increases after eight to nine years. Common issues include stuck window regulators, failed wiper motors, or loose suspension systems, mostly due to component fatigue from daily use. Maintenance is crucial—ensure an annual major service to inspect brake pads and engine radiators; avoid aggressive driving to reduce transmission stress during use. Buick's reliability is average among similar brands, with a moderate failure rate—not excessively high but still requiring vigilance. Addressing minor problems promptly can prevent costly repairs and ensure travel safety.
