“Took the vehicle in 3/19/2021 @ 6076 Mileage for a steering wheel shake, the dealer has tried numerous times to fix it by trying to balance the tire and rotate the tires, it only masks the problem and the steering wheel shake comes back. The shake can happen at any MPH. I finally took it to another shop called discount tire and dynamic 4x4 alignment. Discount tire said there was coupling in the stock tires Nitto Grappler, so I replaced the tires with Michelin Defenders this only masked the problem. On 9/25/2023 a local Toyota Technician and I took a ride together to see if he could duplicate…”

“I have attempted to use the SOS button 4 times in different days and in different locations, only connecting once and the rep. claimed she couldn't hear me that only time I "connected." The system causes premature battery drain (even while the car is off, it draws power) and doesn't work in its intended way as a safety/rescue tool. This is an expensive feature that fails to work while locked in with an inferior cellular service provider through an exclusive contract between Toyota and AT&T.”

“UNKNOWN but not really a "Safety Issue" in the true sense of the meaning. Front Brakes. Loud squeal from brakes under cold climate conditions. Dealership has inspected but nothing found. Mentioned NHTSA # 10190453 & TSB #T-TT-0636-20 REV to the service manager but they stated that there is/was no official "TSB" for brake squeal issue on my vehicle. I believe they were referring to a Toyota "T-SB-#######", rather than the "T-TT-0636-20 REV". I did not get any info from dealership since no official "TSB" is published?”

“The car shakes when going at speeds as low as 48 mph and as high as 68 mph that I know of. Typically, it shakes heaviest from the mid-50 mph range to the mid-60 mph range. I rarely Drive the full speed limit for energy conservation reasons, so I cannot tell you how much higher it goes on the range.

“Steering wheel shakes at highway speeds (58-64mph). Steering wheel has shaken as much as 1.5 inches back and forth, causing vehicle to shake while driving at high speeds. The problem has been confirmed by the dealer and has been in 6 times to try to fix it with no change. The problem started the second week we owned it. It gets progressively worse.

Suspension 4

“I am writing to express my deep concern and frustration regarding the X-REAS suspension system in the Limited Edition 4Runner manufactured by Toyota. Specifically, I am addressing the alarming issue of suspension failure experienced in vehicles at just 45,000 miles, posing significant safety risks to drivers and passengers alike. The X-REAS suspension failure in the Limited Edition 4Runner is not merely an inconvenience; it is a serious safety hazard that puts lives at risk. The abrupt failure of the suspension system at relatively low mileage creates an unpredictable driving experience, jeop…”

Exterior Lighting 1

“Similar to NUMEROUS newer ('12+) vehicles, the instrument cluster gauge needles light up even when the headlights are not on. Therefore when driving the vehicle, the driver isn't aware that the headlights are NOT ON at night (and there are no DRL/daytime running lights to warn oncoming drivers), which means that the vehicle is driving at night WITHOUT any lights on. People are going to be killed this way; both the driver and innocent motorists driving near this vehicle. I nearly got in a head-on collision last night because the vehicle headlights weren't on after sundown (but I listed crash,…”

Power Train 1

“BRAKES ARE NOT FUNCTIONING PROPERLY, THE PEDAL GOES WAY DOWN TO THE FLOOR BEFORE ENGAGING ANY BRAKES. AT IDLE THE BRAKES SEEM TO FUNCTION FINE, AFTER DRIVING AT ABOUT 10MPH THE BRAKES GO BACK TO NOT WORKING AGAIN. DEALERSHIP SAYS THE BRAKES ARE "NORMAL" AND I WAS TOLD TO DRIVE IT HOME EVEN THOUGH IT WAS STILL HAVING THE ISSUE. TRANSMISSION IS NOT SHIFTING PROPERLY EITHER, IT GETS STUCK AT 4000-5000 RPM SOMETIMES AND THEN SHIFTS INTO THE NEXT GEAR. THE BRAKING ISSUE OCCURRED EVEN WORSE GOING DOWN A HILL AT 55MPH RIGHT BEFORE IT WENT IN FOR SERVICE.”
