Business ProfileforGoudy Honda

I recently had an issue where all the sensor lights in my car went on telling me the my tires had issues, navigation has issues, auto correction issues, brake issues and there are other notifications on my dash that flash and I cannot remember. I brought this into Goudy Honda of Alhambra **********. After inspection I was told that it was a misfire issue related to a gasket. I also brought in my BCM recall paper to have them update this too. I was quoted $4800 not including the tax and was informed that it would cost $187 for the diagnosis no matter what the circumstance was if the warranty didn't cover the cost. I provided them with my maintenance invoice from what I had going back a few years. I didn't keep them all but had 5 of them in hand but the warranty department claims that eventhough I had the hard copy of the invoices there was never anything submitted formally through either the honda system or carfax so they won't honor my warranty and they denied to cover the cost of the repairs. If this was a gasket and it was engine related I feel it should fall under the warranty regardless if its a 3rd party that changed my oil. This was pretty much all that was done to the car since I bought it in July 2019. I feel that Honda won't honor this because they can use the 3rd party mechanic as an excuse, this shouldn't matter since the failure was a gasket deep inside the engine. I didn't race my car everyday so how would that occur unless its a defect with the car. They sold me a lemon and won't honor the warranty using an excuse.
