Our car is ...
Our car is a 2006 Cadillac DTS Lux III purchased new, now 3 yrs old. We took the car in April 2009 for a windshield washer recall. We have always had the car serviced at the dealer (we no longer have a dealer in Grass Valley, CA). When the car was ready after the windshield recall fix, they told us they did and update on the Engine Control Module (recall 07132 off the repair order). It may be a Service Bulletin rather than a recall. I found document ID # 1993220 (# 07132), it also covers some 2006 Buick Lucerne, Chev Cobalt, Saturn ION, Buick Rainier, Chev TrailBlazer and GMC Envoy. We did not receive any notification about the ECM update, but are sure glad to have it fixed.
The acceleration problem is gone, thank god. It was very frustrating and took a lot of extra braking (also dangerous). This acceleration always happened with foot on the brake just as we turn into our driveway. A couple of years ago, I went to the dealer and drove another new 2006 and 2007, they both had the acceleration problem. We also have the GPS updated DVD and have a clock we can read on the GPS display. We haven't been on a trip to see how the maps are working.
