I purchased this 2026 Toyota RAV4 Plug-In Hybrid brand new, about two weeks before this incident. At the time of the incident the odometer read approximately 170 miles. While driving at about 50 mph, the vehicle suddenly decelerated as though braking (without me pressing the brake pedal) and would not accelerate when I pressed the accelerator. At the same time, these warnings appeared: "Hybrid Startup Malfunction," "Hybrid System Malfunction," "AWD Malfunction," "System Malfunction," and "Check Engine." I stopped safely and powered the vehicle off and on. After the first restart, the display did not show the odometer reading or battery percentage, although the battery charge bar remained displayed. After a second power cycle, both reappeared. The vehicle then drove normally, but the Hybrid System, System Malfunction, and Check Engine warnings remained; the Hybrid Startup and AWD warnings had cleared. The vehicle had not been repaired or serviced since purchase. I have never boosted or jump-started its 12-volt battery. An authorized Toyota dealer performed initial checks, found no error codes, and could not duplicate the failure. The dealer said another customer's 2026 RAV4 reportedly had a similar issue weeks earlier; they test-drove that vehicle about 150 miles without reproducing it and ultimately reset its warnings. This was a sudden, uncommanded deceleration and loss of acceleration while moving at highway speed. Loss of propulsion in traffic, especially at 50 mph, creates a risk of a rear-end collision or inability to maneuver to safety. The vehicle is available for inspection, and dealer records are available. In the days before this event, once or twice daily during normal driving, the vehicle displayed a blue message stating "Accident detected, recording started," despite no collision or driver input. The vehicle has never been in an accident. I do not know whether this is related, but it may be relevant to an electronic, sensor, or control-system fault.

As I was traveling on the highway, the sunglasses holder opened and my sunglasses fell out and impaired my vision. FORTUNATELY, I was able to maintain control of the vehicle and the glasses did not fall to the floor and interfere with the gas or brake pedal operation. The sunglass holder latch does not operate properly and does not latch or stay closed. Called Toyota and was informed there were no other reports or TSP advisory, however encountered many similar incidents on. Reddit threads.

I report this issue because the malfunction may affect vehicle safety and I found many cars owner has shown this malfunction just like me on the toyota forums. The dashboard is showing a general “System Malfunction – Visit Your Dealer” message along with several driver-assist warning icons. The illuminated symbols appear to relate to the car’s ADAS / safety systems (advanced driver assistance systems), including: Lane keeping / lane departure assist malfunction Pre collision system disabled Traction/Stability control malfunction Adaptive cruise control unavailable Blind spot or parking assist disabled Automatic high beam system malfunction Door / sensor icons problem The first time was happened on Apr 29 and all safety system was not working and the dash board screen got frozen. I brought my cars to dealer for 3 days but they couldn't find any problems. On May 15, it happened again. All safety system stopped operating and I brought car to dealer and after 2 days they still couldn't find the problem. My car is still at dealer until now.

While driving on the freeway, I heard a loud explosive sound and pulled over to inspect my car. I found the panoramic sunroof glass shattered, but there were no signs of impact or objects hitting the vehicle. Mike Calvert Toyota inspected the car and denied warranty coverage, claiming impact damage despite no evidence. They advised us to contact insurance, but we believe this is spontaneous shattering not our fault.
