XXX XXX XXX XXX XXX 11/13/2025 the federal safety agency Office of Defects Investigation 1200 New Jersey Avenue SE Washington, DC 20590 Toyota Motor Sales, U.S.A., Inc. 19001 South Western Avenue Torrance, CA 90501 Subject: Complaint Regarding Torque Converter Shudder – 2018 Toyota RAV4 AWD To Whom It May Concern, I am submitting this complaint regarding a serious transmission defect in my 2018 Toyota RAV4 AWD, specifically a torque converter shudder that has been documented by Toyota technicians. The vehicle exhibits pronounced shuddering between 25–50 mph under light throttle, consistent with the torque converter failures previously acknowledged by Toyota in earlier RAV4 models (2013–2015). Toyota has extended warranty coverage for torque converter replacement in those earlier models, yet my 2018 RAV4—despite showing identical symptoms—has been excluded. The dealership has quoted me $9,000 for a full transmission replacement, even though the issue is well-documented and appears to be systemic across multiple model years. This situation raises serious concerns: - Toyota is aware of the defect but has limited coverage to select VIN ranges. - The cost of repair is excessive and disproportionate to the defect. - Consumers are left without recourse despite clear precedent for warranty extension. I respectfully request: 1. That the federal safety agency investigate whether the torque converter shudder in 2016–2018 RAV4 models constitutes a broader safety defect. 2. That Toyota extend its warranty program to include affected 2018 RAV4 vehicles. 3. That Toyota provide reimbursement or coverage for necessary repairs to restore safe vehicle operation. I am prepared to provide service records, dealership documentation, and correspondence confirming Toyota’s acknowledgment of the defect. Please advise on next steps and ensure this issue receives the attention it deserve INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had my car for about 2 1/2 years, never been in an accident or anything .. I take the car for an oil change and when I picked it up they informed me that they ran a diagnostics test that indicated that my transmission was out. They asked if I’ve been in any accidents, but I assure them that I have been any accidents at all. The car has been driving perfectly fine but after that news, the car has been dying out! I don’t travel far in the car or go on road trips so I’m not understanding how the transmission has failed!

1. It is not clear what component or system failed. While driving at around 70 mph, after 2-3 hours of driving, there is an audible "clunk" sound from below the car. Typically this is followed by a shuddering of the engine/transmission/power train. The car momentarily looses acceleration/speed. There are typically one or two "clunks" alternating with one to four "shudders." There is no action when depressing the accellerator. At this point I typically pull over to a rest stop or side of the highway to let the vehicle rest, and then re-start the vehicle, which causes the issue to not re-occur when the vehicle is driven again. Yes the vehicle is available for inspection upon request. 2. My safety and others' safety was put at risk by the vehicle not being able to accelerate when the accelerator is depressed. 3. The vehicle has been inspected by multiple Toyota dealers, including Watertown Toyota, Wellesley Toyota, and Wesboro Toyota (all in MA). The dealers all say they cannot duplicate the issue during test-driving an so they therefore cannot fix the issue. 4. No other warning lamps, messages, or symptoms appear prior to the failure. The most recent date this incident occurred was November 12, 2023. However this issue has been occurring a few times a year since approximately 35,000 miles. At approximately 55,000 miles I tried to get Wellesley Toyota to address the issue prior to the powertrain coming out of warranty at 60,000 miles. I reported this issue to Toyota recalls on Monday November 13, 2023. Toyota's case number for this issue is 231113002026.

Last week my transmission suddenly and completely failed while driving on the interstate, creating a major safety concern. I was stranded on the interstate for three hours until I could be towed off. The car only has 56,000 miles on it and there were no warnings that there was any problem with the transmission. The transmission previously failed at 7,000 miles and was found to be defective and replaced at the time. How can a car with 56,000 miles on it already have had TWO transmission failures?

I have a similar complaint as the federal safety agency ID Number: 11210210. On several trips over the past few years, while traveling at speeds of 70 mph, my vehicle would have a loud bang and then start bucking and jerking when I briefly let off the accelerator. About 2 weeks ago, I was looking at my speedometer at the time when the bucking started happening. The EV light came on for a brief second and the needle on the charging gage briefly dropped down into the charging status. It seems that the EV motor was trying to engage at speeds causing the bucking. This seems like to be a major concern when traveling at highway speeds. The engagement of the EV motor at highway speeds is like unintended engine braking that possibly lockup the engine and loss of control.
