Orem Toyota - Service Center

We have two 2008 Prius's. Between them they have had 5 oil changes. Three went fine, two were disasters in terms of time and organization. The first problem time it took over 3 hours (1 was the estimate oil changes. Three went fine, two were disasters in terms of time and organization. The first problem time it took over 3 hours (1 was the estimate) because of some kind of coupon which was expiring. If I had been told it would be that long, I would have left; I was assured it would take between 45 minutes and an hour. It was 2 hours before I got back, only to find that nothing has been done. The second problem time the car sat for 1 1/2 hours with no one noticing it had not been moved. When I got back to pick the car up after the 1 1/2 hours I had been told it would take (oil change and replace seat belt), my car was the only one in the service area and the lights were all blinking. There were are least 5 people at the service counter who could easily see the car, but none of them had bothered to see what was going on. A new employee evidently did not follow through and went to an orientation meeting instead and no one else had noticed anything unusual. That is a 60% acceptable rate. The purchases were fine, the work is fine, the organization is a mess. We will not be returning there. More
