2024 BUICK ENVISION Engine Problems

The vehicle was taken in for the oil level not registering on the dip stick 5235 miles on the odometer, they said it was 2 quart oils low. They said they would do an oil consumption test and to bringv it back in 2000 miles. We took it back with an odometer reading of 7451 and it was again 2 quarts oils low. There is an oil consumption issue on this vehicle.

Prior to the first oil change which is recommended at 7500 miles, I check the oil and there was NO oil present on the dip stick...none, not a drop. I had to add 1 3/4 quarts to get it in the accepted range. We took the car for its normal 7500 mile oil change and informed the dealer, upon inspection and oil change they said nothing was wrong with the car. About 2000k miles after that oil change I checked the oil again and again it was well over a quart and 1/2 low. I added enough oil to get the oil level into the accepted range. I made an appointment with the dealer and they looked at the car and said it was 3/4 of a quart low upon arrival and want me to start an oil consumption study. My concern is if this car is using that much...
