Is It Normal for the New Regal to Shake When Starting the Engine?
3 Answers
New Regal experiencing slight shaking when starting the engine is a normal situation. Below is a detailed introduction about the Regal car: 1. Overview: As one of the most successful strategic models of the Buick brand, the Regal car has won the favor of users with its trendy, dynamic, and technological product image and comprehensive technical strength. The Buick Regal integrates General Motors' global advanced technologies, inheriting traditional advantages while focusing on the continuously increasing car usage demands of consumers in the new era. 2. Others: The drive method is front-engine, front-wheel drive. The body weight ranges from 1430 to 1535 kilograms. The engines include a 1.5T SIDI direct-injection turbocharged engine and a 2.0T variable cylinder turbocharged engine. The chassis suspension consists of front enhanced MacPherson suspension and rear enhanced multi-link suspension.
I've been driving the new Regal for almost a year, and it has slight body vibration during ignition, which is actually quite common. Every time the engine starts cold, it shakes once or twice because the machine transitions from stationary to operation, just like how a phone vibrates slightly when powered on. I was initially concerned too, but the 4S dealership said minor vibrations in new cars are normal, and it stops shaking once the engine warms up. However, if the vibration persists or becomes severe—for example, if you feel the steering wheel trembling—there might be an issue, such as worn spark plugs or loose engine mounts. Once, after starting in snowy weather, it shook badly, and the diagnosis revealed a faulty ignition coil, which was fixed after replacement. I recommend new owners pay attention to regular maintenance, like checking the engine condition every 5,000 kilometers, to prevent minor issues from escalating. Safety first—if in doubt, visit a professional shop.
Engine body shaking during startup is quite common in vehicles. As a sporty sedan, the new Regal's engine design incorporates slight vibrations as part of the normal startup process. The sudden load increase during ignition, combined with the turbocharging system's response, may cause the body to shake a few times. This phenomenon is typically more noticeable during cold starts or in low temperatures. From my own observations, it usually disappears after the engine warms up. If the shaking becomes too strong or unstable, it might indicate ignition system issues such as spark plug carbon buildup or fuel injection problems. As an owner, it's good practice to keep records: note the timing and frequency of the shaking. If abnormalities occur, such as the engine light turning on, don't hesitate to drive to a repair shop for diagnostic checks. Regular maintenance like using quality fuel and keeping the air filter clean can prevent many potential issues.
