Camelback Toyota took care of a recall on the wiring harness and since that date I have had numerous problems - lost my keyless entry, lost my speedometer, lost my horn. D & b auto found some problems at the tune of $428. 70 (got my horn, speedometer and keyless entry working again - this was 8/12/13). Then approximately September or October, my car would start lurching and felt like it went into neutral and I would loose my speedometr - no engine light would come one - we tried several time to find out what was wrong - d & b auto checked out my speed sensors and found them to be okay and suggested it was my instrument panel and told me to call dick's speed-0-tech - I did and was informed that it could not be the instrument panel on a 2003 Toyota Corolla - suggested I call sam's compu -tech - I did and he said he could not help me until an engine light came on. In the meantime I found joe the tech and he found the ecd connector (e8) not fully seated (locked) - not this is after the recall by camelback Toyota and then I still had the problems of the car lurching, going into neutral and loosing my speedometer so joe the tech came back and we spend approximately 8 hours checking out the instrument channel and guess what we found (done by camelback Toyota) - first he looked at the wiring under my dash and said "this is not factory" and then we found 6 zip ties holding the wires going into the instrument panel box and again he stated this is not factory. We found the wires would not stay in the box because it had obviously been twisted - so we fixed them and the car has been okay since - this was 10-20-14. Now you are telling me I have another recall on this - I cannot go thouth all this crap again so what are you going to do about it?.
