Toyota RAV4 harsh shifting problems

Filed Sep 24, 2026 · Suspension · MA

Mechanic said he thought rear lower rearward; non-adjustable control arms, lateral arms were a recall. They were falling apart. I've been complaining about a clunky noise for a year or so.

**VEHICLE:** 2020 Toyota RAV4 LE **VIN:** [XXX] **CURRENT MILEAGE:** 126,776 miles **PURCHASE DATE:** October 2020 **COMPONENT:** Automatic Transmission (Power Train) **PROBLEM DESCRIPTION:** On XXX, I took my 2020 Toyota RAV4 LE to a transmission specialty shop (TJ'S Transmission Service Inc., Bedford, PA) because the automatic transmission was slipping while driving. The professional diagnosis (Invoice #XXX) confirmed the following stored fault codes: P2681, P2816, P08BA, P2713 The technician also confirmed that the transmission fluid was black and contained metal debris, indicating significant internal wear of clutch/band components. While researching these codes, I found that Toyota previously issued Technical Service Bulletin (TSB) T-SB-0160-18, titled "Transaxle Whine Noise, Harsh Shift, MIL ON, or Reduced Power," which acknowledges these SAME fault codes (P2816, P08BA, P2713, among others) as a known problem in the 8-speed automatic transmission (UA80/UB80 family, manufactured by Aisin). This TSB was officially issued only for the 2017-2018 Highlander and Sienna models, but the 2019 and later RAV4 uses the same transmission family (UB80E/UB80F) for the 2.5L engine, suggesting this is the same design or manufacturing defect that has not been officially acknowledged for this model. This issue represents a safety risk, as unexpected loss of power or transmission slippage while driving (for example, when merging onto a highway or passing) can create a dangerous situation for the driver and other vehicles on the road. I am requesting that the federal safety agency investigate whether a similar failure pattern exists in other 2019-2021 RAV4 vehicles equipped with this transmission, and that consideration be given to whether Toyota should extend coverage of TSB T-SB-0160-18 (or issue a specific one) to include the RAV4. No repair was performed at this time due to the high estimated cost without warranty coverage. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Jerks during acceleration. Lurching sensation when acceleration from a stop or after slowing down for a turn. The engine control module (ECM) not communicating effectively with the transmission, leading to searching for gears, rough shifting and low speed hesitation.

While driving the vehicle on an uphill stretch of highway with cruise control set at approximately 65 mph, the vehicle suddenly slowed down without warning. A distinct clunk was heard at the same moment. The cruise control system attempted to restore speed, and the engine became noticeably louder, but the vehicle struggled to return to the set speed. The driver tapped the brake to disengage cruise control and manually pressed the accelerator to resume normal speed. The trip was completed without additional events. After parking, the check engine light illuminated and the cruise control system became disabled on all subsequent drives. No warning indicators were present at the time of the initial failure, and there were no vehicles ahead that would have triggered the collision-avoidance system. Two days later, the vehicle became an intermittent no-start and eventually failed to start entirely. The vehicle was towed to a dealership for inspection. Technicians confirmed an electrical malfunction and reported that the multiplex ECU was likely experiencing an internal short. A parasitic draw test showed an abnormally high current draw of approximately 113 mA, which disappeared when the dome-light fuse and later the multiplex ECU were disconnected. The failure is intermittent and appears to involve an internal electrical short within the multiplex ECU. The sudden loss of cruise control function, abrupt deceleration, and subsequent intermittent electrical behavior created a safety risk, as the electrical malfunction occurred without warning while the vehicle was in motion. The issue was confirmed by a dealership service department.

I have the 2019 Toyota RAV4 Adventure that was manufactured with a defective differential, per T-SB-0067-20, Toyota has acknowledged that the differential were defective and that affected thousands of 2019-2020 RAV4 Adventure and Limited trim models. The defective part number is 41110-42050 and the new, superceded part number is 41110-42054. I reached out to Toyota numerous times to rectify the issue has the differential clunks and could seize causing loss of control. My vehicle was deemed a "total loss" due to hail damage and Toyota refuses to assist because of the total loss, but the vehicle was manufactured with the defective part and my vehicle suffers the VERY same issue as that a non-total loss vehicle suffers. The title status is irrelevant as the defective differential was installed BEFORE the total loss, so the title status is inconsequential. This is a safety concern because the differential could fail due to seizure, shatter, explode resulting in a loss of control and injury to me the driver and others on the road. I've expressed this numerous times with Toyota.

I purchased this vehicle used in july of 2023. There had been a persistant clunking noise in the rear when the road is bumpy along with some stabilty or swaying feeling. I had it inspected by independant mechanical shops. I was advised to replace the shock absorbers and the stabilizer links which I did. The rt rear shock abosborber was bad. March of 2024 I took a road trip to florida. First long trip since replacing the parts. On the drive down I was by myself and felt as though the rear of the vehicle was swaying back and forth a lot worse than before changing the parts listed above. I thought maybe it was the condition of the roads. On the way home my son was following me in his vehcle. He had told me that when the "swaying" feeling is happening the rear of the vehicle is moving separate to the front. The clunking sound is still there and that stability issue seems to have worsen since changing the suspension parts previously listed. There was a point in driving home in the rain where I definitely felt the abitlity to control the vehicle was difficult and dangerous. I will be taking the vehicle to be inspected further. I've read information on a toyota forum that there are other owners experiencing this issue. I do have vidio and you can see my body rocking back and forth in the driver seat while it's happening and the hood swaying but am unable to upload it.
