Recalls on the 2020 Toyota 4RUNNER
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

SUSPENSION
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, jeopardizing the stability and control of the vehicle. This instability can lead to loss of control, especially at high speeds or during emergency maneuvers, resulting in potentially catastrophic accidents. Furthermore, it is deeply troubling to discover that Toyota may have been aware of this issue and yet failed to take proactive measures to address it. The apparent negligence on the part of Toyota in acknowledging and rectifying the problem reflects a blatant disregard for consumer safety. By continuing to produce and sell vehicles equipped with a defective suspension system, Toyota is knowingly putting drivers, passengers, and other road users in harm's way. As a concerned consumer and advocate for road safety, I urge the National Highway Traffic Safety Administration (NHTSA) to launch a thorough investigation into the X-REAS suspension failure in the Limited Edition 4Runner. It is imperative that Toyota be held accountable for its failure to address this issue promptly and effectively. Furthermore, I implore the NHTSA to take decisive action to ensure the safety and well-being of all motorists by compelling Toyota to initiate a comprehensive recall and repair program for affected vehicles. Every individual has the right to feel safe and secure while operating a motor vehicle.

EXTERIOR LIGHTING
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, fire, fatalities to get your attention, as I submitted this same issue about 8years ago for a similar incident with a Nissan Leaf that narrowly missed running me over as it was driving without any headlights on/LED gauge cluster was bright enough to see the drivers face, and NOTHING has changed in the auto industry for safety on this widespread issue). How can the automotive industry and NHTSA have let this happen? Instrument cluster gauges should not have ANY backlighting unless the headlight switch is physically activated by the driver. This issue is even worse with the new LED/virtual gauge cluster screens.

WHEELS
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 the problem. At 67 and 68 we were able to duplicate the problem when the steering wheel shook the passenger side of the car shook. The technician and I swapped and I was able to duplicate the problem as well. I was stopped at a red light and took off after the tires were warmed up. When I reached 67 or 68 mph the steering wheel began to shake and he confirm that the vehicle shook too on the passenger side. I have experienced shaking in the steering wheel previously but now its being felt in the vehicle too. Toyota sent out a technician on the last issue and I was told they found something and then I was told there was nothing. Please see notes below as I have documented every occurrence and can provide maintenance documentation too.

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.

WHEELS
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. The car has had the wheels rebalanced three times (installation, upon purchase from the dealer and on a take back to the dealership), the alignment has been checked twice and I have spoken to the tire manufacturer about the tires being the cause of this. I took the tires into an authorized retailer to no avail. With everything checked, including a road force balancing of the tires, my 4Runner still shakes disturbingly. I called a service advisor at another Toyota dealership today (they were not the seller). In describing the problem to him, he cut me off and said it is a known problem. He went on to share that the dealership had been in contact with Toyota Corporate. It is disturbing for me as a driver, my passengers and from an engineering standpoint; shaking can never be good. It could easily cause premature and unnecessary wear to drive, suspension and steering parts. It could lead to a serious and fatal accident over time. The shaking, I imagine, could also lead to a problem in less than ideal driving conditions such as rain, snow or ice as well.

It doesn't happen all the time but it is fairly consistent. Especially through the drive thru line is when you notice it Took to dealership dealership said there was nothing wrong with it

Thirteen months ago I purchased a 2020 4 Runner from Parker Toyota. Last week my sunroof exploded for no reason, there were no rocks or debri that caused this. This is clearly a manufacturers defect of the glass used. I am thankful I wasn’t covered in shattered glass or worse, cause an accident. The picture shows my shattered sunroof, it has tape holding it together so it didn’t cave in on me.

SERVICE BRAKES
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?

STEERING
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. Tires can be balanced and it comes right back a few days later. Toyota corporate states that it is a known issue and “is a characteristic of the vehicle” cause by “harmonics.” Tires have been road force balanced, tire/wheels swapped, driven with no drive shaft, driven with computer to turn off torque converter, drive shaft swapped- all with no change. Toyota would not agree to provide loaner car after requesting buyback arbitration. I was told it would take 30-45 days to get arbitration started, and was told to drive the vehicle during that time period. I was told to return loaner and drive 4Runner that was still shaking. I asked dealer to give me something in writing saying that the vehicle was safe and mechanically sound before I left, and they refused.
