Team Honda in Merrillville refused to fix my recall unless I paid for diagnostics
All of the safety system and efficiency systems had failures which made us take to our local Honda dealership for evaluation. After the first visit we were told that they could not find the problem, although they saw all of the error messages.
Upon going to start my vehicle it would not start. I ended up jump starting the car and going to buy a new battery. I replaced the battery even though repair facility stated battery was at 78% and in good state. Two days later I went to start the van again and the battery was again dead.
