We live on a farm so the fact there is rodents is no surprise. However strangest thing is the knock sensor harness has been chewed completely off two times in last two months. . When this happens it causes power loss. With the extra shielding the wire has tells me it gives off a low frequency that would irritate most animals and me at this point since the part is never available. If it actually gives off a frequency, it is absolutely unnecessary and a complete nuisance.
The car lags, stutters, and hesitates on acceleration and in consistent speed situations. Sometimes doesn't respond quickly to gas pedal and sometimes it does. It is very unpredictable and unsafe. I never know which response I will get. Has also almost completely died after putting the car in park.
Picked up my Toyota Highlander in April 2023 I have had to return it to the dealer on two occasions for check engine light and secondary break failure I'm at the fourth check engine light and secondary brake failure report now it has been inspected by the dealer and tried to remedy it too times already currently getting ready to return to the dealer with the third check engine light secondary brake failure message.
Vehicle unpredictably hesitates during light to moderate acceleration in all driving modes (sport, normal, and eco). This is especially dangerous when crossing in front of oncoming traffic from a stop or slow speed. Had a certified mechanic drive the car and verify the problem, but the car's systems don't report that there is a problem, so he had no answers.
