Unknown vehicle won’t take speed. Only reaches 30 miles an hour, thereafter vehicle starts to excessively shake. Lane assist does not function.

Just bought a 2006 4runner and did not think to check underneath for anything. I noticed on the passenger side of the frame huge rust spots, it's rusting from inside the frame out to the surface. It's bad. I googled what I should do to fix it because now I'm out 7k for what I thought was a reliable SUV. They sell patch kits online requiring me to purchase the kits and have them welded to the frame by a professional after they clean the rust completely. That's expensive. Toyota should definitely take this seriously and not fight this claim. No truck that year should rust this bad. In fact I've bought a 77 chevy c10 that was a farm truck most it's life and it did not have any frame rust what so ever. There's multiple claims on facebook and other 4runner specific groups online that have this same issue. A recall needs to happen. What if I didn't notice and I let my wife and kids ride in the SUV and the frame snaps in half down the highway? you recalled other models do to frame rust, but not the same year 4runner. Please help us 4runner owners fix this because all in all it's a great SUV Toyota makes some of the best product out there, we just want to keep them on the road.

While driving in a snowstorm on an interstate highway at night on 1/25/2021, two important safety systems failed due to ice and snow buildup on the vehicle. Failure 1: the pre collision system (pcs) warning light illuminated indicating temporary failure of the pcs system (see photo 1). This was due to ice and snow buildup on the forward sensor, located on the front grille (see photo 2). Problem could only be rectified by stopping and physically removing the ice buildup, as referenced in the Toyota owner's manual, page 252. I recommend the sensor be relocated in front of the rear view mirror high on the windshield, where windshield defrost and the angle of the glass will reduce or eliminate the buildup. In the short term, perhaps a plastic air deflector or shield can be fabricated which will keep ice from interfering with the sensor. Failure 2: headlight high beam failure. The design of the headlight cover facilitates ice buildup over the entire structure (see photo 3). Since the high beam bulb is inboard and aft of the low beam bulb, it cannot penetrate the ice buildup at all, and makes the high beams completely ineffective. Weather conditions were: outside air temp: 30 to 32 degrees; night; heavy snow; altitude: 3,000 to 6,563 feet.

On December 8 , 2020, the above referenced vehicles engine stalled three times while in driving mode. On all three occasions, the vehicle was moving at a speed less than 40 mph. The vehicle restarted after each stall, when the gear shifter was placed in park. The vehicle seemed to be running out of fuel and/or having fuel pump problems. The fuel level of the vehicle was half full. I purchased the vehicle October 21, 2020. Todate, I have experienced 5 engine stalls. The vehicle had approximately 28. 700 miles. The malfunctioning of the vehicle is an ongoing problem that has been reported the dealer as well as butler Toyota in macon georgia who informed me that they were not sure if they could diagnose the problem without keeping it for weeks, possibly at my personal expense. I chose not to leave the vehicle under the circumstances. I will return the car to the seller under the 90 day certified warranty agreement. Also, I will continue to pursue whatever remedy Toyota may provide under the vehicles remaining warranty. I traded a 2013 Toyota highlander on the vehicle in question. I am a very disappointed Toyota customer who is very concerned about the safety of the vehicle in question.
