Engine Problems of Cadillac CTS

The contact owns a 2004 Cadillac Cts. The contact stated that the engine would exhibit an abnormal increase in rpms when driving 50 mph and above or while sitting idle with the vehicle in park. The vehicle was taken to a mechanic who replaced the throttle body sensor and the accelerator pedal sensor. The failure recurred two weeks later. The vehicle was not taken to the dealer and the manufacturer was not contacted. The failure mileage was 99,300.

My 2008 Cadillac Cts v6 di awd has a dangerous acceleration lag when you step on the gas to pass or get out of the way of a hazard in road. There is about a 1-2 sec lag between stepping on pedal and rpms moving, and about another second or so before any pick up happens. Doesn't sound like much, but no other car I have had, did this. At the speed of oncoming vehicles, a 1-2 second lag can mean a 30 - 60 yards of distance being traveled by an oncoming car or truck. That sight fills up rear view mirror fast. In my opinion, this is a serious design flaw and potentially death causing defect. This happens anytime I need quick acceleration, and is also happening in other cars I tried at dealership to see if it was just mine.

- the contact has a 2003 Cadillac Cts with a current and failure odometer reading of 71000 miles. The contact stated that she was driving under cold dry conditions at about 55 mph, while exiting the freeway she notices dark smoke coming from under the hood of the vehicle. The contact was able to reach a parking lot, and when she lifted the hood she saw flames. The fire department came out and extinguished the fire, but were unable to determine the cause of the fire. The contact had the vehicle towed to the dealer and they also have been unable to determine the cause.

1. I purchased a used 2003 Cadillac Cts in 2005 with 45,000 original miles from a gm dealership in ontario, oregon. It was reputed to be in excellent mechanical condition by the gm mechanics. 2. This vehicle has since cut engine power spontaneously several times on the freeway and in town, presenting sudden and serious danger to driver, passenger, and other motorists as the vehicle must be steered powerless to the median/shoulder. Once we were in the middle lane of 75 mph freeway traffic and several vehicles were nearly involved in an accident. 3. Gm tech's are unable to diagnose the problem after 7-8 attempts, so it continues to recur. Gm refuses to repurchase the vehicle despite their inability to diagnose, enforce the warranty, and the obvious danger to all involved. The better business bureau would not arbitrate because mileage was over 24,000. I am currently seeking legal counsel, but feel this vehicle should not be on the road.

After heavy rain and if undercarriage gets wet "oil pressure low" warning alert. Requesting driver to stop engine. Dealer can not find anything wrong.
