We have a 2015 RAV4 and are experiencing the shudder. Took it to our local certified mechanic who confirmed its the torque converter and was nice enough to print out the warranty bulletin posted by Toyota and encouraged us to contact them for a warranty repair. Well good ole Toyota won't budge on the repair stating our VIN number is not one of them covered under the warranty. How can this be when the vehicle is clearing experiencing the known problem?!?! To all of you 2015 RAV4 owners....fight it! We have filed a claim with the Federal Trade Commissioner who in turned advised us to file a claim with the Attorney General's office where the vehicle was purchased as well as the Better Business Bureau.
