Since I purchased the vehicle 2 yrs ago I have complained to Dodge and GMC about the issues involving the car. It has hessitated when pushing on the gas after being in a stop. It has accelerated on its own on a stop light gone all the way to 4. I had to put it on park for it to stop.the car has completely turned off on me several times then the check engine light turns on and then after 2-3 days turns off along with the road hazzard light. When I take it to have it checked they find nothing. I finally got tired of it took it to Dodge to have it diagnose paid $150.1. they did not offer a loaner car 2. they had my car for almost 2 days just for a diagnossic test 3. they did not have a hybrid specialist there nor did they sent it to one. They didnt find nothing wrong with it just suggested to do transmission change, change the wires to the spark plugs and change the spark plugs after doing all that. The problem continued. I then took it to GMC paid another $150 for them to do a diagnosis test. They also did not find anything wrong with it but seen that it had a extended warranty of the throttles and said that could be it. After changing that the problem still continued. The only thing that the guy told me from me explaining the problems is it could be the brake senser. Paid &170.00. Problem still continued nothing has changed. This is dangerous and could cause an accident, the car turning completely off on me hessitating to drive and accelerating on it's own when on park is dangerous. I have done more than my park in taking the car to see what's wrong with it yet no one can find nothing wrong with it the machine says nothing when I want the problem to acure to show them what I am talking about it does not do it. I don't know what else to do. But this is dangerous very very dangerous. I paid alot with no results to show for it. Please look into this and have it checked.

Loss of brake pressure, pedal went almost to floor. Brake warning annunciator stabilitrak caution annunciator service brakes soon message on dic stabilitrak failure message on dic driving home from work, radio on, air conditioning on, driving for about 10-15 minutes a guy in front of me does a quick lane change and turn in front of me. I have to step on the brake hard but not super hard. When I did this the brake pedal went further than normal and all of the above warning lights illuminated on the instrument panel. A). I slowly pull into a parking lot (2-3 mph) and the pedal goes almost to the floor. Almost cannot stop. B). I shut off the vehicle and restart but the lights come on as soon as I press on the brake. I do this several more time, check brake fluid reservoir but the same results. C). after about the 6 time restarting, I hear a small motor running ( brake accumulator / modulator ? ) and the pedal begins to get firm again and the warning annunciators extinguished. D). I continued driving home slowly with no further faults. Didn't think of checking the voltage until everything was good, at that point it was indicating 15vdc. This problem has occurred intermittently many times since then. Have taken to keeping one foot on emergency brake. The dealership replaced brake master cylinder but this did not fix problem. Dealer ordered the electric pump (brake modulator) and two weeks later dealership states GM cannot locate any parts to repair the vehicle. Part remains on order. Vehicle not operable without brakes.
