2007 Mazda CX-7 Vehicle speed control Problems

“1. I was pressing on the gas pedal to accelerate as I was merging onto the highway via an on-ramp. The car was previously driving normally without any problems. 2. The car kept on accelerating after I removed my foot from the pedal. It continued accelerating even after pressing on the brakes (I could feel / smell the brakes working but the car would continue to accelerate even though no foot was on the gas pedal). The car continued to do this even after I put the car in the manual transmission mode. …”

“I purchased my 2007 Mazda CX-7 from a dealership in greensburg, pa in february of 2014, it was purchased as a used car with only 36,500 miles on it.

They want all maintenance records for the time I have owned the car in order to make a determination of whether it will be covered under warranty. I purchased an extended powertrain warranty which covers the engine and turbo to 100,000. …”
