2006 Cadillac SRX Vehicle speed control Problems

“At low speeds when pulling out of a driveway or taking off from a stop sign or traffic light my 2006 Cadillac SRX traction control engages and almost stops my vehicle in the middle of the road. I have almost been hit several times by other drivers because of this problem. I took my Cadillac to a local GM dealership (dale earnhardt chevrolet) in newton nc. On my first visit to the dealer they found a multiple misfire (code p300) and a faulty oil pressure sensor (code p0521 & code p0523). …”

“Random traction control engagement and stability system both noted in radio -- but no conditions to warrant it and no codes to explain it--when checked nothing found. Causes dangerous unexpected slowing of vehicle both at initial acceleration and turning which is contrary to what would be expected by surrounding traffic. Then sluggish w deceleration but no check light and mechanic can't figure. Now will only drive forward, can't drive or even push in reverse. This event was preceded by loss of acceleration on highway (sluggish) -- also dangerous and still ni engine light!”
