Yesterday I was shocked to learn my 2017 SR5 with 48,000 miles requires a new torque converter! The drivability problem started 2 weeks ago and became worse each day. Last month the 5 year 60,000 mile powertrain warranty expired. At purchase in 2017 I fortunately got the platinum service agreement which should cover P & L for “new” transmission. My dealer received Toyota approval for repair and will confirm parts and loaner availability in a couple of days.
I had hoped our 4runners would be reliable for the long term, but I am now disenchanted.
You still have the opportunity to purchase the extended service agreement-I am so glad I did!
