PCM issues on AWD 300C-Help!!

Help... Anyone else out there with either RWD or AWD have PCM problems? Mine (actually mothers 05 C AWD) was replaced first at 800 miles and two weeks at dealee. Now we have 3,500 miles and having exact same problems as before the PCM replacement. Original problem was engine would rev to about 3000 rpm when in park - would not come down. When shifting into ANY gear, car would litteraly lurch forward or back, even with me standing on the brakes. Gas pedal would be completely unresponsive. Now, same rev problem, but with an added twist - at different times, different warning lights are coming on and staying on (ABS warning light and Electronic Throtle Control light, which could explain unresponsiveness of the accelerator). Waiting for appointment tomorrow to get car in to confirm PCM is the problem again. I can't be the only one having this type of issue, can I?

I've had a litany of problems, including having the PCM replaced for a loss of power problem.
None of the problems have re-occurred once fixed, but I am keeping an eye on the front tire feathering due to bad initial alignment.
Having to return for addtional service, especially for something that may not have been fixed properly the first (or second) time, can be a bummer, but it's the only way to eventually get satisfaction and exercise the warranty. I've been such a good customer of the loaner car department that the staff knows me on sight. It's been trouble-free for about 2000 miles now. Hang in there, it's worth it!
And hang in with the forum. You asked if anyone had the same problem. Apparently nobody did so they didn't reply. Additionally, we don't necessarily visit the forum daily (at least I don't), so a specific reply may take a few days. It may take a little more than 1 hour and 17 minutes for someone to come along who could reply to the specifics.
