I took my car there for the first (and last) time last week. They put the WRONG oil filter on my car, causing my car to lose a fourth of it's oil in half a day (when I noticed the leak).
Since I was in another part of town, I took my car to a different service center, where they told me what the problem was and fixed it for free.
If I had not noticed the leak, my engine could have been ruined.
I returned to this Jiffy Lube the next day. They seemed dumbfounded, and DID NOT EVEN APOLOGIZE. They did refund my money, but I will never ever go to a Jiffy Lube again.
Pros: Convenient Location
Cons: , Unapologetic, Potentially ruin cars
