Towing can be a hassle, but you want to make sure you do it safely. Unfortunately, you cannot flat tow a Buick Enclave. The owner’s manual specifically states that flat towing your Enclave can damage your vehicle.
Instead, you can dolly tow or trailer tow your Buick. This will require some extra equipment, but it will also ensure that your Enclave isn’t damaged during transportation. You can rent the necessary equipment from most moving truck rental companies (like U-Haul) for a relatively affordable price.
