2019 Toyota Avalon

While driving the vehicle and stopped at a red light or stop sign, the vehicle failed to accelerate when pressing the gas pedal. I pulled to the curb and turn off the car. After I start the car again, it will work fine. The vehicle has failed to accelerate several random times while driving and stopped at a light or stop sign causing a hazardous situation. The last time it occurred was on September 1, 2026. It has happened three times prior to this date also. No vehicle codes or warnings lamps were displayed on the dashboard at any time.

On two occasions, 8 months apart, our car started braking on its own while driving in traffic. In both instances, the on-screen alerts indicated the LDA and simultaneously the check engine light. Neither time were we trying to switch lanes. In fact, the first time we were on a one-way street. In both instances, we were able to cruise over to a parking space before the car completely stopped avoiding a rear-end collision. Once we got in the space, we turned the car off and back on but it would not go forward or backward. We sat for 30 minutes or so, started it up and was able to get it home. We took the car to the Toyota dealership the next day. We got a call from the dealership in a few days stating the mechanics drove the car but the issue did not occur so we had to go in to the dealer and sign an authorization to allow access to the car's computer. About a week went by before we received a call stating they were waiting for an engineer to come in and diagnose the problem. Two weeks later, we got another call informing us the engineer would be delayed in getting to the dealership and asked if we wanted to pick up the car. Obviously, driving a car that we no longer feel safe in was not an option so we informed them to keep it until the problem was addressed. Weeks went by and we were not contacted so we sent a letter to the Corporate Office of Toyota. A case was opened but two weeks passed before we heard anything. We reached out and spoke with a representative who said they would have the initial rep call us. We never heard back so reached out again in a week and spoke with yet another rep who said there are two case numbers and the case is in progress and also told us there was "some kind of dispute" but we needed to speak with the case manager who opened the case and they would have her call back. Here we are nearly 3 months later and there has been no resolution. We've not heard back from the dealer in over a month and the Corporation in nearly 2 weeks.

The transmission needs to be replaced. My car has 75,146 miles and my check engine light came on while I was driving down the interstate. I took it to the Toyota dealership and they confirmed that the transmission needed to be replaced. I was told it would cost $8,600. I was looking for any recalls on my car and saw there were multiple lawsuits involving the transmission in my car and other Toyota and Lexus models. The primary lawsuits involve millions of vehicles equipped with the UA80 8-speed automatic transmissions.

I am writing to formally report a serious and ongoing safety issue involving the Telematics / Data Communication Module (DCM) installed in Toyota vehicles. This issue presents a clear risk to driver and passenger safety and warrants immediate corrective action. The DCM is responsible for critical telematics and safety systems, including SOS Emergency Assistance, Safety Connect, and Remote Connect. Failures of this system are not merely inconveniences—they directly compromise emergency response capabilities and vehicle reliability. Documented Failures and Safety Risks: Severe Battery Drain: Defective DCM units drain the vehicle battery even when the vehicle is off, leaving drivers stranded and unable to start their vehicles—potentially in unsafe or remote locations. Loss of Emergency Services (SOS Failure): Malfunctioning DCM systems disable or impair SOS functionality, preventing drivers from accessing emergency assistance during critical situations. This represents a direct risk of injury or death. Loss of Connected Features: Remote Connect capabilities (remote start, unlock, vehicle monitoring) are rendered inoperable, indicating systemic communication failure. System Errors: Persistent errors such as “Connected Device Not Supported” demonstrate loss of communication between the DCM and the vehicle network. System-Wide Malfunctions: In severe cases, DCM failure can disrupt the infotainment system or broader vehicle functions, effectively “bricking” key systems. Demand for Immediate Action: Given the safety implications—particularly the failure of emergency SOS functionality—I am requesting that Toyota take the following actions without delay: Issue a voluntary safety recall for all affected vehicles, or Provide a cost-free repair or firmware update that fully resolves the DCM defect, and Notify all affected owners proactively of the safety risk and available remedy. If this issue is not addressed promptly, I am prepared to escalate this matter through formal
