Automatic transmission shifter unable to shift -- beginning in 2017 (3 years into the new car), the transmission began to exhibit periods where it was very difficult to shift. Moving the transmission shifter from stationary to any of the moving positions (r, d, 3, 2, 1) required significant strength. Beginning earlier 2019, check engine light code p0705 begin coming and going on the dashboard display. Three trips to the dealership thus far has failed to properly diagnose and remedy the issue.

Rodents ate wiring harness in engine compartment, while driving in the city, the trac and check engine light cane on. I returned home and retrieved error code p0333 on my reader. I took vehicle to doxon toyota for service / repair. They confirmed code and said that rodents had chewed knock sensor wire harness. I was told that tis was not covered by warranty even though the vehicle was less than two years and less than 9000 miles of use. I consider that making electrical components out of material that is attractive and tasty to rodents a traction and air-bag safety concern, I.e. Soybean based wire insulation. I have been operating motor vehicles since 1963 and have never had this happen to ant vehicle I have owned.

Rodents caused over $3,000 in damage by chewing on cables that are made from one or more of the following (soy, rice husks, wood, sugar, vanilla, peanut oil, and straw; references: www.synlube.com/incredibleediblecar1.htm ; www.google.com/?gws_rd=ssl#q=why+do+rodents+eat+cables+on+cars+made+in+japan ; google: rodent damage toyota ). Toyota refuses to pay for the damage. My auto insurance said it might pay (still waiting to find out) for the damage, but there is a $501 deductible. Toyota is the worst offender of making edible vehicles. If I had known this in advance, I would researched to see which vehicles have edible cables. I will be selling my 2015 tacoma asap and finding another pick-up asap that rodents won't eat. My brother lives in the mountains in new mexico where there are many varmits, and they never ate the wiring on his old chevy tahoe, but rodents have chewed on the wiring of my toyota tacoma, and my mother's toyota 4-runner, and a friends nissan marano. The proof of tasty cables attracting rodents is overwhelming. My engine light came on, the engine was running rough, and the trac off light appeared. I took it to the toyota dealership immediately (in lewisville, tx) the next morning at 8:50am. Numerous cables were damaged and many parts had to be removed to repair the damage. The problem is, if they replace it with more tasty cables, the same thing will happen. The vehicle was stationary on the driveway by the garage. There is already a car in the garage and some tools, and my pick-up is too large for the garage.

Electronic stability control turns off when check engine light turns on. Vehicle stability is compromised. Almost rolled the truck over. Dealer technician reports that rodents ate the hose connecting fuel injector air pump to valve which triggers the ecu to fault and cascades failure to stability control. Technician reports that toyota is using edible soy-based plastics for engine hoses and wiring harness and rodents are causing extensive damage in toyota vehicles. Toyota does not cover related repairs under manufacturers warranty. Was quoted $1000 to replace one hose since dealer claims toyota does not sell individual replacement part for this hose. Therefore, the ESC will not get fixed for some time.
