Our 2012 Prius had 179,000
Our 2012 Prius had 179,000 miles on it and had been burning oil badly. One 800 mile trip with oil changed and topped off plus fuel additive before the trip and by the time we arrived it burned 2 quarts with nothing registering on the dip stic. Started the engine day after arrived and engine was shaking and making loud noise to discover the no oil. After adding oil it ran quite and smooth but the engine light stayed on. Took it to the nearest dealership (Gosch Toyota in Hemet CA) and they said the engine was no good and needed to be replaced as pistons were leaking out oil. It had developed a problem of burning oil at about 100k miles. I followed the Toyota recommended oil change until I realized oil needed much more often change interval. This was the problem since 10k mile interval was ridiculous. I dropped from 5k down to 3k change. why did Toyota tell owners to change at 10k? That ruined our engine and our 2012 Prius lasted only 179k miles. We ended up having to practically give it to the dealer (they gave us $1000 for our 2012 Prius that was loaded and in great shape otherwise) and get a new car. On top of all that our experience with Gosch Toyota was a nightmare series of non stop screw ups and rip offs. We've been a Toyota family for decades with numerous Toyota vehicles but the experience and disappoint with our 2012 Prius and subsequent purchase nightmare with Gosch Toyota has left us questioning ever getting another Toyota.
