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

Read complaint narrative

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.

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.

System malfunction—the ‘brake’ alert flashed and chirped when there was NO obstacle on the road. Safety issue—I was about to hit the brakes but I realized in time there was no need. Confirmed? No not at this time. Possibly have it reviewed at next maintenance. No inspection yet. This has occurred infrequently in the past

NHTSA complaints are reports submitted by vehicle owners and other consumers. Complaint counts do not represent the percentage of vehicles affected and do not by themselves establish that a safety defect exists.

A higher complaint count can partly reflect how many vehicles were sold, vehicle age, and other factors. CarIQ does not yet normalize complaint counts by vehicles sold.

Service Bulletin/Repair Instructions

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.

Service Bulletin/Repair Instructions

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
