Bought a 2019 CPO (also still under factory warranty) and had it for two weeks, then the check engine light came on. The vehicle continued to run fine. Dealer diagnosed a bent rod due to water intrusion which defied explanation as we never drove through water during the two weeks we drove it. Dealer/Toyota denied warranty coverage because of “water intrusion.”
The insurance estimator inspected the HL yesterday and reported to us that there may be a bent rod but no evidence of water intrusion (air box and air filter were dry, no milky oil). He has reached out to the dealer for an explanation of why they concluded there was water intrusion and denied warranty coverage.
I know very little about this kind of thing (though a good bit more than I did two weeks ago) and would like to know what can cause a bent rod besides water intrusion. Any other comments are welcomed.
Side note: When we purchased the HL, the front and rear tires were mismatched (not permitted by CPO requirements) and the CPO checklist indicated that features our HL does not have passed inspection. This causes me to question the integrity of the CPO inspection including whether they ran a DTC or could have reset the codes before we bought it.
