AutoNation Toyota Arapahoe

I was really dissapointed with the service on my 2020 Tundra. The muffler mounts had broken loose in 2 places. I was hoping it was covered by the extended warrenty that I purchased through the dealership. I learned my truck has a duel exhaust that was installed after market so it was covered. So, I understood and paid $275 to have it fixed. 4 weeks later, one of the new welds broke loose. I brought it back in and they ended up charginb me an extra $110 to fix it. That was after they took off 15% because I complained. They added a new part which was $15 and I was happy to pay for that. However, charging me for the labor which was only needed because they didn't fix it right the first time was super frustrating. I will be looking for a new service center.
