I noticed a few wet spots under the vehicle, but I couldn't establish where it was coming from. On 25/Nov/2015 while I was driving, the vehicle's temperature gauge suddenly went up, followed by "engine overheat" message and alarm. I was on a long bridge in a construction area, and I was forced to stop on the side in a very dangerous location. I had the vehicle towed to a repair shop where it was discovered that there was absolutely no coolant remaining. The shop mechanic added more coolant with a dye and let it run in order to find out where it was leaking from. There was no leak at all. I was told to drive home and come back the next day for a check. I went back the next day, and there was no sign of leakage. After about 1 week I started noticing the wet spots on the the ground again. This time I took it to the Buick dealer, and they couldn't find any sign of leaking coolant. I checked on the web and realized that this is a common problem with Buicks. Many owners have expressed their frustration with coolant leaks whose course could not be established. I am now stuck with a vehicle that could literally go up in flames any momment. I believe that this is a potential design issue that should be established.
