Put key into ignition port and heard and felt a klunk. Key was then freely moving and connecting to nothing inside the ignition chamber. So vehicle would not turn over at all. Had towed to town closer to home. And Currently having towed to mechanic shop for further evaluation. The only symptom the car was having previously was a mysterious scratching sound coming from what sounded like the right side of the hood near the firewall. Took to mechanic and he drove the car and heard the sound but could not pin point it, said nothing was scrubbing the fan or anything else he could see. And to bring it back if it got worse. Never did we think it was the starter nor the ignition chamber. The only way to know now....is to replace it and see if that noise is still there. There were no other warnings. The danger in this is being stranded. Still needs to be evaluated by mechanic.

Electrical system malfunction began (to my best calculation & recollection) in summer 2021 with the first of four battery malfunctions in one year. Each time, AAA discovered low battery response and recommended battery replacement. This time around, battery was replaced about two weeks prior, due to battery failure/AAA reporting would not accept charge. THE NEW BATTERY FAILED (8/3) and the starter broke while attempting to charge. Mechanic repaired starter and battery accepted the charge. No problem, right? Wrong. This driver drove about 30 miles and while driving, the electrical system shut down altogether. With I believe ALL WARNING LIGHTS LIGHTING UP, extremely dangerous situation. NO BREAKING, NO STEERING, NO WARNING. Fortunately, it occurred in a suburban residential area as opposed to the highway. SECOND tow to my mechanic and now, after a full week, no diagnosis, though the car has been running in the shop. This is an intermittent problem. I suspect the alternator.

Dear all I bought this car in 2016. It was imported from USA to UAE now registered in Abu Dhabi. The car completely stalled while stopping at inclined position for about 10 minutes in front of a security barrier. READY lasts for less than 5 seconds and disappear. The car could not be started again for three month. Local dealer [XXX] Indicated they are not handling imported vehicles except from GCC region. A local repair company identified the problem by error code P0A78 but told the repair cost will be heavy. What could I do with my car which still under recall in USA for repair of the same INVERTER problem? Appreciating your help. Best regards [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Water gets into the body of the vehicle over time. Came outside one day after rain and my passenger carpet was SOAKED all my windows were up and my complex don-??t get flooded. Car smells like mildew in cabin! Middle of July I came outside and all the lights were on the dash, no rain the previous day or during, and car wouldn-??t start. Took it to the dealership and they can-??t explain how water got into my car but magically the sunroof drain was clogged with water.

"check vsc" system with accompanying continuous beep noise, brakes become hard to push/activate. This started a few weeks ago, and would happen intermittently, and progressively longer in the dysfunctional brakes phase. I had an employee at auto zone clear the code 2 days ago, but the problem started again, intermittently upon vehicle start, but would go away shortly, with normally responsive brakes. This intermittent issue occurs when I am driving, therefore this is a serious road hazard as my brakes become significantly less responsive when the problem occurs. In other words, this occurs when stationary and when driving, intermittently.

Rear caliper blew while driving - almost lost brakes on highway - vehicle was unsafe to drive. Ignition coils failed (twice) while driving - lost power - almost got hit by a truck steering fluid leak - dealer says to get entire steering replaced or may lose steering while driving!! all this started at a mere 42,891 miles - and we narrowly averted possible accidents at high speed!

The rear lift gate handle is melted and gooey. When I touch it to open the rear door, I get this gooey tar-like substance on my fingers. My dealer told me it requires a complete replacement of the door's electrical components to fix. Seems unusual that this is electrical, but if it is, then something is generating an unusual amount of heat to melt the rubber cover. My car is black, but it is stored in a garage...and the handle is covered and out of the sun.

The exterior lift gate button has become a black sticky gooey mess. It is concerning that an electrical issue could be melting the black rubber button. Found many other cases of this with Lexus and Toyota sienna's online. Has something been done about this occurrence?
