2009 Chevrolet Cobalt Vehicle speed control Problems

“I bought a used 2009 chevy Cobalt 2 years ago in 2017 with 119k miles. It has been nothing but a headache with things going wrong! The biggest issue is the code p2135 that sends the car into reduced engine power and the engine shakes violently. This is very scary especiallywith 3 young boys in the car with me. I have replaced the entire throttle body, ECM, accelerator pedal assembly with new sensor, crankshaft positioning sensor, camshaft sensors, spark plugs and spark plug wires. …”

“When accelerating hard to get on the highway from exit or going up a hill the accelerator gets suck. The car will not slow down with our foot on the brake as hard as possible. We just pray we can get over to break down lane without hitting anyone. The only way to stop car is to put in neutral, keeping your foot on brake and pulling the emergency brake. Once the care is in park you must shut off car and restart. It you put the car in drive without shutting car off it willl start running by itself again going 65mp in the break down lane. …”

“On thursday october 9th, 2014 I was driving east on rt 70. It began to rain heavily at approximately 4:50pm and I attempted to use the brakes on my vehicle. The brakes were suddenly very stiff. I didn't think they were working. I was in the left lane when this occurred and immediately put on my emergency lights and tried to move to the middle lane, to the right lane so I could go to the shoulder. When I attempted to switch the lanes, the power steering wasn't working. I managed to move the steering wheel slightly so that I could switch lanes. …”

“I was trying to turn my car on and I kept hearing a clicking noise. The car would not start no matter how many times I tried to restart it. I waited another five minutes it started and as I went to put the car in reverse it shut off again. I put the gear back into parking and then tried to restart the car, everytime it turned on it would shut off as I put the gear into reverse. So as I turned the car on again I went forwards to turn outward from the parking stall around the cement block but then the car shut off again and I hit the cement block which left a dent on the right side of my car. …”

“The dic shows the reading of each tire pressure backwards, for example right front wheel is actually the rear right wheel, and left front is actually rear front. Also I am unable to use the cruise control. The lights turns on but the car does not engage in the same speed for the cruise control.”
