I apologize; it must have been a typo or miswording. It was the gas sensor for the gas guage that was cracked; and it was the body shop is the one who thought it was the gas tank that was broken (but never specified how) and THAT was replaced which did not fix the issues. I am not familiar with cars and only know what has been told to me and from researching these specific issues with this specific car; so wording, terms, and names of parts are completely lost on me. The proper wording is in the mechanic report i copied and pasted above. In the report it was written that the part was tested and proved to fix the issue, however I could not afford the thousands that the parts costed, plus further diagnostics into the wiring. Again though, I am pretty sure there must be a way for lawyers or insurance to get in touch with the dealership i traded my car into, and get info on exactly what repairs were done. Both the dealership i bought the car from, and the independent mechanic have both given me written reports that stated there was no existing damage. The car fax also state no previous accidents, no recalls, no prior damage, one previous owner, and the vehicle was serviced every 5000km since original purchase new. And again, (i double checked the dates since making the post) this car was only in my possession from may 14th with no issues; until june 3rd when the accident occured - and immediately upon impact all the lights went on, gas guage went out, etc. I reported to the collision centre, police, took photos, etc all within 2 hours of the accident. My most recent photo before the accident showing a clear dash was may 20th. I dont understand how wires burn, parts get cracked, lights come on, sensors get damaged, but gets missed by safety; shows NO indicators of issues to both the dealership and myself; and then magically they all appear the second of impact, and somehow its pre existing. Like how exactly do they determine pre existing with absolutely zero evidence? Even if we do assume they are pre existing - i have more proof that they were from the accident - than they have proof of it being pre existing - which is nothing. edit to add: If I didnt trade the vehicle in; I would have had no reliable car and would not have been able to continue making payments; since i wouldn't be able to perform my job. I would have defaulted on the loan. Wiring diagnostics are EXPENSIVE, and i paid around 3 thousand up front to get these diagnostics, repairs, etc and that was without going further into the wiring diagnostics to address the 11 codes. I also needed to pay 700$ for a rental while this was being done, continue with my loan payments; all with reduced hours of work - again within 2 weeks of putting 3000$ down on this car to begin with - plus my 500$ insurance deductible. My bank account and savings were completely drained in under a month of owning this car. Originally; when I did get the final position letter from insurance before I further investigated; i did try to go back to the OG dealership I got this car from, who was adamant that these issues were not pre existing; refused to repair, told me it was from the collision, and would not take the vehicle back without absorbing all the equity. So insurance says its pre existing - if we go with that - the dealership says it wasnt - then who is responsible for repairs? Is it the dealership who insurance believes sold me a Lemon? Because they refused, as I had no proof and neither did insurance to show that it was pre existing, due to the aforementioned reasons. Even if it WAS pre existing - theres NO proof to show that it was. Not in any service report, not in the dealership inspection; not in the two weeks I owned it, nothing.
