CVT Transmission experienced a ‘catastrophic’ failure without any prior warnings such as service lights, noises, or other signs of trouble. After driving for about 1 mile, I was attempting to accelerate to merge onto a highway, and the vehicle ‘rumbled’ for a moment and then lost all acceleration. Luckily, there was a shoulder I could drift to, but otherwise I would have been stuck in traffic, potentially causing an accident. The vehicle has 48k original miles, a clean title, no accidents, and no other mechanical issues have ever occurred.
