On January 22, 20222, I was traveling down highway 400 in Sandy Springs, Georgia and my left (driver's side) // rear tire EXPLODED and I almost lost control of the vehicle. The main part of the tread completely separated from the rest of the tire, but I was able to recover it from down in the woods. I have not taken it to a mechanic or tire shop yet, so I still have the rim that has the remnants of the sidewall attached to it as well as the tread portion of the tire for inspection. I didn't hit a pothole and wasn't aware of any object that I ran over. It was a sunny day; the pavement was dry and it was about 45 degrees. The tires were filled with nitrogen. I inspected all tires before I started driving and I didn't see anything unusual or previous damage. There were no warning lamps or messages before my tire EXPLODED. The car did sustain damage to the driver's side rear bumper cover and possibly suspension components. All four tires were purchased from Costco in September 2020 when the vehicle had 113,429 miles. The vehicle currently has 114,668 miles on the odometer and approx. had 114,648 miles on it at the time of the incident. All four tires are Michelin Pilot Sport All Season 4. The front has 235/50ZR 18 and the rear has // had 255/45ZR 18.

Navigation system fails (computer), I checked online seem a lot car owners have a similar problems which not effecting navigation only also effect the audio system and drain the battery. Mechanic advice me to replace the battery and I did, problem still the same. For a high end car with low miles seems not right. A new computer navigation system cost over $2000. Seems the german design those systems to fail to keep their business going.
