Buick Verano motor ticking under load while going uphill, unknown oil consumption issue on Buick Verano

Some Buick Verano owners report experiencing a ticking noise from the motor under load, particularly when driving uphill, along with an unknown oil consumption issue. These problems may stem from a low oil level or pressure, which can lead to metal-on-metal chatter due to inadequate lubrication. Additionally, some owners have noted that their engines consume oil at a faster rate, necessitating frequent monitoring of oil levels to prevent potential complications. Worn or damaged main bearings have also been reported as a source of ticking or knocking noises, especially under heavy load conditions. Regular maintenance, including checking oil levels during refueling and adhering to oil change intervals, is essential for maintaining engine health. Owners are advised to promptly address any drops in oil level by visiting a dealer for an oil consumption test, and to start diagnosing ticking noises by checking oil level and condition to prevent further engine damage.
