I took my car into Jiffy Lube on the 31st of July. On the 1st of August on my way to work my vehicle locked up. First light I noticed came on was the oil light then all the other lights came on. I parked my vehicle and checked the oil, but there was no oil. I call my boyfriend to come by and had him inspect my vehicle. Turned out that Jiffy Lube did not either tighten my oil drain plug or has forgotten to put it back it. Because of their little mistake, my vehicle is not driveable. Jiffy Lube is offering to put in a USED engine claiming that it has under 100k miles on it, but they need to take it to their shop. Do I have the right to sue for their negligence and not completing their job as promised costing me and my boyfriend time from work and me not having a way to travel?
