Timing chain, engine noise.
On August 6,, 2014 I had taken my 3 kids to the lake @ dreher island state park. Upon getting ready to leave I put on breaks to see what my son asked me. For no reason the car started moving forward & I couldn't get it to stop get the wheels to turn as it was very hard & pushed the emergency breaks & it kept going till it went in the ditch on a concrete terracotta causing it to bend a piece of what was told to me the a frame & under the front end! I called the dealership & told it wasn't possible. Before this happened I could park my car & the engine would act is if it was trying to go w/o me mashing the gas or anything then idled down repeatedly acted as if it was going to shut off! I've even had 2 buy 2 new batteries, fixing to buy another! they said a connection was causing the battery to be drained & cells killed. On the interstate 2 days ago I had the cruise control on, for no reason it started losing speed then would start catching back up on it's own & I turned it off! the motor made a screeching noise! I have no idea what's going on! even my tail lights wouldn't come on last night until I mashed the breaks a few times, cut off the lights, & restarted the car! my major issue is now I'm going to have to file a claim for the incident & I had no part of being @ fault & can't explain what happened! it still idles wrong & the cruise control light comes on @ times w/o me touching it! I'm beginning to worry about the safety of my children as well as myself, but especially my kids! what can I do? please help me as this can't be normal! so far the engine light has came on, power steering light, air pressure light, & @ one point a red light came on & went off before I could see what it was! if you could do anything@ all to help & assist me I would be truly grateful! all I'm told is parts aren't in to fix some kind of recall, but what I don't know! thanks & god bless!.
