general problems of the 2009 Cadillac STS

When driving in rain the smallest amount of water will cause the reduced engine power to engage and it does not go off until the vehicle has sat for a long amount of time. Extremely dangerous. First the abs light comes on and then you lose power. 3rd row led taillight out. . . 400 to fix. Purchased in March of 2018 with 93k miles. Currently at 104k.

Vehicle detects fault and displays message to service stability control system. Specific problem not yet diagnosed. Within a few moments, the display states that engine power is reduced. This causes a very unsafe condition as the vehicle slows to 10-15 mph. Pressing gas pedal causes transmission to downshift to lower gear slowing vehicle further. Cannot safely maneuver in traffic, brakes require much higher pedal pressure due to low vacuum boost after engine power reduced. Insufficient warning that this is happening. Problem is not with engine or powertrain, but engine power is cut (engine runs very rough as a result) in response to detected stability system error. Engine runs fine if turned off and restarted. No overheating, oil level is fine, gasoline is good, no external problems. After restarting car drives fine initially, event recurs within 1 mile. Very difficult to try to justify this kind of intentional vehicle control behavior. Extremely poor design that causes an unsafe condition when a stability system error is detected.
