NHTSA Complaint #11507548 — 2015 TOYOTA RAV4

At 100,000 miles my 2015 RAV4 started experience intermittent shuttering during aacceleration when car is shifting gears. It feels like driving over a rumble strip. I read about the ZH1 torque converter extended warranty for 2013-2015 Toyota RAV4 models. This has been a frequent enough issue that Toyota has extended the warranty up to 8 years or 150,000 miles, in which they will replace the torque corverter and ECM at no charge. I called Toyota Customer Care and gave my VIN number. According to Toyota, my car is not covered under the warranty becuae my car was built in May 2015 and the warranty only covers RAV4s built through Nov 2014. In their extended warranty bulletin, Toyota claims the RAV4s that aren't covered have different software logic. I have called Toyota back to find out what is different about my car's software logic, but they claim they do not know and to ask the dealer. Today I took my car into the dealer to have it diagnosed. Sure enough, the torque converter is locking up and I need to have the torque converter clutch replaced and ECM reprogrammed. The dealer said they dont know the difference between the software logic. The dealer recommends i call Toyota Customer Care back and ask to speak to a field representative, who should know that information. So far, Toyota has not been helpful in answering my question, but I am planning to get to the bottom of this. I have read that many other RAV4 owners are experiencing the same issue, where Toyota claims they are not covered because the car was built outside of the designated window. I don't think the issue was corrected properly in the later toyotas and that is why others are experiencing the same problem. This is a safety concern. The ststor clutch will cause the torque converter not to work as efficiently, driving down your gas mileage. In some extreme cases, the convertor may violently self-destruct. https://www.rav4world.com/threads/2013-2015-rav4-torque-converter-shudder-warranty-extension.311617/
