HELP! any advice appreciated ASAP 2007 GS350 RWD, Car died in driveway last week at 96k, towed it to a mechanic my brother recommended, after jumpstart failed to get the car moving ( 9 amps across the terminals). This small time mechanic replaced the alternator and did an oil change +alignment. I picked it up Saturday morning. I drove to work and back on Saturday and Sunday, 50 miles round trip, and no issues. This morning, while driving to work, the Check VSC warning and Engine Malfunction light came on, and I was having acceleration issues, There was rattling sound coming. I pulled over and pulled the gas cap (no gas was put in the interim) and same warning at restart. Had it towed to the same guy, and he tells me no warning signs and nothing wrong with it. He would take it for a test drive and see if it happened again. Is there an OBD memory module that he can access and see what the issues where this morning? The lack of acceleration was not in my imagination, but the rattling may have been. There was a giant diesel truck behind me for 3 miles and seemed to tailgate me until I pulled over into a parking lot, he matched my acceleration and stops to the tee. If he can't find the problem, is it safe to drive the car? At what point does it become unsafe? The owner's manual is of no help, it just says pull over immediately and call Lexus. I'm out $950 for the first repair, and I think that my car may have been beyond his ability to fix. I think he messed something up while replacing the alternator, and I am not sure howto proceed. Any advice would be appreciated.

Hello! I just got a 2007 GS350 RWD, and was playing with the bluetooth phone setup. I can't get the handsfree system to answer a call. I get a weird error "terminated by network" on the nav screen and then it hangs up. We are using a sprint moto slvr. I can call out using the phone book, but it just won't answer the calls. i can also call out using the phone and the calls are transferred upon the other party answering. i tried to turn off the auto answer in 5 seconds in the setup, and it does not make a difference. Any ideas? thanks in advance.
