As Service Manager at a local Napa Autopro shop, this post just ticks me off. In this day and age there is no reason that this car should not have been fixed the first time it went into the shop. Parasitic draws CAN be found! All it takes is time to isolate suspect circuits. Find a shop that is competent with electrical issues, subscribes to a service such as Identifix or IATN where technicians all over the world share fixes for obscure problems, and does not charge flat rate. Removing the fuse only removes the symptom but doesn't fix the problem. What it does do is isolate the problem to a circuit serviced by that fuse. A competent shop should find the fault within 3 hours. The limp mode issue may or may not be related. Did the limp mode issue end when the fuse was reinstalled? Any check engine light?
