I have a 2006 Liberty CRD. Recently the power window regulator failed on the driver side (common problem - I know). I took it to the dealership, had the regulator and window replaced per the TSB, paid them and was happily on my way. What happened over the next few days has me troubled. The
passenger side window failed the first time I lowered it just 4 days after being in the shop. Chalked it up as coincidence knowing it is a common point of failure in the Jeep and had them replace that window and regulator. The next day the driver side
rear window failed the first time I used it after it had been at the dealer. I now suspect that I've been taken advantage of by a crooked dealer.

I'm not going back there but wanted to get others' opinions or similar experiences with this kind of situation. Could it be an incredible coincidence or am I stupid to even think it might be?
Thanks,
