Rant: Shady business from Findlay Toyota

So I brought my vehicle in to get diagnosed and repaired after a break down to Findlay Toyota. I’m still under powertrain warranty at under 5 years old and only around 40,000 miles on the odometer. Immediately upon visual inspection they said because there was aftermarket parts on the vehicle my warranty was voided. This is without them actually diagnosing the problem which would therefore make it impossible to identify the actual cause. Later they say they believe the issue is internal engine no further information provided. It’s a complete cop-out from Toyota and their service department to then determine my modifications have any relation to the problem. I followed regular maintenance and had modifications running on the car for 2 years without problems when casually driving on the freeway I suddenly bogged out and ran rough. They couldn’t do better than to jump to the accusation that it’s the owners fault and offer no help. Supremely disappointed there were no other options or compromise offered to me. Terrible service towards someone who’s purchased their vehicle thinking they made quality vehicles. I’ll take my repairs somewhere else now where I feel more confidently they’ll actually take the time to identify the problem and fix it for a fair price. This will be the last time I do business with Toyota as a whole so in the future my next vehicle purchases will be with another company and I’ll absolutely share my experience so that friends and family never have to deal with the same shady practices of Toyota Findlay… Who had shop suggestions for me? Thanks everyone!
