The contact owns a 2008 Cadillac Sts. The contact stated that the TPMS sensor intermittently illuminated. The vehicle was taken to an independent mechanic. The technician replaced all of the tires but the failure persisted. The technician was unable to determine what was causing the failure and referred the contact to an authorized dealer. In addition, the contact mentioned that the electronic locks failed to secure. The contact was able to use the key fob to secure the door but that did not prevent the failure from happening. Also, the contact mentioned that there was a sudden increased in engine rpms and it was difficult to slow the vehicle down.

Purchased as a "program car" 5/21/08 with 7017 miles on odometer, auto has been a constant source of trouble which selling dealer crest Cadillac of venice, fl seems unable to correct. Myriad problems occur but fail to register on recorder which prevents corrective action. I do not fault dealer staff but blame overall problem on Cadillac's refusal to consider defective interactive computer network from stupidity or cupidity. On the last trip to the repair facility eleven items were addressed with three not being addressed with problems not listed in recorder or unable to be duplicated. Since Mar. 20, 2010 most of the problems have recurred and I have recorded 16 specific malfunctions to date some of which I consider to be safety concerns. E.g sudden failure of cruise control system and/or difficulty in disengaging it; repeated attempts required to open windows and lock or unlock doors; malfunctioning of windshield wipers; with 125 lb. Wife in front passenger seat, "passenger air bag off" indicator is lighted. Is indicator faulty or is passenger air bag inoperative when it should be functional? I have a large dossier documenting numerous trips to the dealer to address over twenty issues and repetitions and have never had more than a half dozen problems with any of the 40 or 50 previous vehicles I have owned over the past 60+ years. It appears that since these numerous intermittent problems do not register in the vehicle's recorder, Cadillac is using that as an excuse to avoid addressing the real problem, that is, the computers themselves. I entreat you to force Cadillac to replace the defective computers before I just give it up as a hopeless situation and sell the auto. Although I have always bought american autos for over 60 years, I shall never again own a Cadillac. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
