With estimating my months over a span of 4 months I had my turbo charger replacedbecause it had gone bad. I was out of town the light came on. And when I return I took it to the shop they diagnose it and said it was a turbo charger. I had an extended warranty on the car so they replace the turbo charger with no problems give me a rental with no problems everything was covered.. and a month and a half later my engine light came on and I replaced the purge valve another month or so later the engine light came back on and it was a turbo charger gone bad again. It took about week to find out why the turbo charge went bad. They finally said it had something to do with the return and supply line like there was no lubrication coming through a hose tthat runs to the turbo charge. This is the only place that I've had my oil change since I bought the car from king Cadillac Buick GMC. I went one other place one other time and that was it.I wonder why they did not check the supply line when they change the turbocharger the first time is that not a part of changing the turbo charge. I was told that they have seen this issue before but not a lot.when this first happened I was on interstate 40 on my way to was to salem North Carolina. And I noticed a decline when I went to celebrate on the gas. When it happened the second time I was riding to church here in my hometown and the engine light came on and just riding around hell is as if the car did not want to go like I would give it to gas and it would hesitate or not want to drive.
