2023 Toyota Corolla

On Monday, January 5, 2026 at approximately 3:15 p.m. Pacific Standard Time, in the middle of stopped traffic (leftmost lane, southbound on Van Nuys Boulevard near the Saticoy Street intersection in Los Angeles, California), the vehicle, a 2023 Toyota Corolla Hybrid LE, suddenly started slowly moving backward. The driver pressed on the brake pedal, but the vehicle did not stop. In a panic, the driver removed the key from the ignition, which immobilized the vehicle. While in the middle of traffic, the driver contacted a family member for assistance and the vehicle was towed to the driver's residence. On the following day, January 6, 2026, the vehicle was towed to a service center for inspection. It is unknown if the warning messages observed January 6, 2026 were due to the vehicle being towed. At the service center, a tire was replaced and the brake system was flushed, at the owner's expense. Afterward, the driver continued to operate the vehicle. As of August 5, 2026, this incident had not recurred.

I purchased a 2023 Toyota Corolla LE as a Toyota Gold Certified Pre-Owned vehicle on March 8, 2026 at 61,387 miles. Within 30 days of purchase I began experiencing the following safety concerns: •Vehicle revs to 5,000-6,000 RPM unexpectedly •Violent jerking while driving •Vehicle stalls On April 7, 2026 I brought the vehicle to the selling dealership. The technician confirmed experiencing the jerking and stalling personally during a test drive but documented it as “common operation” and “operating as designed.” I disagreed with this assessment in writing on their service document. A second Toyota dealership subsequently found cracked motor mounts and transmission mounts in multiple locations on a 3 year old vehicle. Replacement of these components did not resolve the issue. Transmission fluid drained at service was nearly black in color on a Gold Certified vehicle that supposedly passed a 160-point inspection including transmission health check. The vehicle is currently at the dealership unresolved after nearly two weeks. The stalling and RPM surging present a serious safety hazard particularly at highway speeds. I am requesting this be investigated as a potential safety defect.

The contact owns a 2023 Toyota Corolla. The contact stated that while driving at an undisclosed speed, the infotainment screen unexpectedly turned on and off. The vehicle was taken to the dealer, who determined that the infotainment system needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 70,000.

Component: VISIBILITY / SUN VISOR Vehicle: 2023 Toyota Corolla Both the driver-side and passenger-side sun visors in my 2023 Toyota Corolla have failed within approximately two years of normal use. The visors no longer remain in their intended position and instead fall downward unexpectedly. When this occurs, the visor drops directly into the driver’s field of vision, creating a significant safety hazard by obstructing forward visibility while driving. This condition can happen without warning and requires the driver to physically move the visor out of the way, causing distraction and increasing the risk of an accident. The vehicle has not been modified, damaged, or subjected to abnormal conditions. The visors were used only as intended. Sun exposure is a normal and expected condition for this component, and failure under these circumstances indicates a potential defect in materials or workmanship. Both visors failing in the same manner suggests a systemic issue rather than isolated wear and tear. The vehicle was taken to a Toyota dealership, where I was initially told the repair would be covered under the manufacturer’s warranty. However, the claim was later denied and classified as “wear and tear” due to sun exposure. Given the function of sun visors, this explanation is not reasonable. This issue presents an ongoing safety concern due to impaired driver visibility. I am submitting this complaint so that this defect can be reviewed and tracked for potential broader impact.

I am experiencing persistent and unresolved issues with the infotainment and display system in my Toyota Corolla, primarily involving Apple CarPlay overriding the driver display. Even when I manually disable the setting that allows CarPlay/navigation to take over the display behind the steering wheel, the system does not retain this setting. After turning the car off and restarting it, the navigation/map interface reappears and overrides the driver display again. This behavior is extremely distracting while driving and interferes with my ability to safely view normal vehicle information. It has created multiple situations where I felt at risk of a collision due to unexpected display changes and distraction. In addition, there are ongoing system malfunctions including: •Volume controls becoming unresponsive (the slider does not adjust sound), requiring the system to be restarted to function again. •Intermittent failure of the phone connection/charging port, where the device does not connect properly to the system. A prior software update temporarily addressed one issue, but the core problems persist. I have been attempting to resolve this through Ardmore Toyota dealership in PA for approximately one year without a meaningful fix or access to a qualified technician. This appears to be a recurring software or system defect that affects driver attention and vehicle operation. I am concerned this creates a significant safety risk for myself and others on the road. No one has taken me seriously even after I’ve gone to several Toyota dealerships over and over and I explained my concerns and they promise that I’ll be on a list of waitlist to be seen by a field tech technician however that has never happened and they are refusing to provide assistance.

I have a Hybrid version of the 2023 Corolla in the SE trim. Everytime the car is cold (engine just started), and I'm pressing the brake, I can hear some clicking noises similar to a CV Axle noise when they are bad. That braking noise goes away as the car heat up. The noise is sensitive to speed, it changes frequency with it. I haven't experience loss of brakes but I'm concerned with the noise and the possibility of it.
