THIS IS FOR TIRE SIZE P265 75 16. To start, I've seen multiple other complaints describing the same scenario and type of incident. Driving along the highway at appropriate speeds, I hear a whoosh/deep pitch rumble, then my vehicle began to vibrate violently. I was luckily able to pull over but had to swerve to regain control of my vehicle once the rumbling and vibration got too severe since it happened so quickly. Witnessed my driver side rear tire completely shredded, no damage along tread material, only on sidewall with multiple tears/punctures. This was a center lane on the highway with no debris. I'm now noticing other similar "tear/wear" signs on my other 3 tires on the vehicle. All specifically on the sidewall along the aggressive tread that the AT3W tires were known to have for extra grip. It just seems to be separating over time.

Frame is excessively rusted. The recall that already exists for this issue only covers certain frames from Japan made with this steel. However, the same frames were imported to America and a large percentage of 4Runners were made with the same steel and didn’t receive a recall. Mine is one of them.

The contact stated that while driving 60 MPH through a slight right curve, the vehicle independently shifted from side to side without warning nearly causing the vehicle to flip. The contact had an independent mechanic inspect the vehicle and the mechanic discovered severe corrosion throughout the entire subframe of the vehicle. The mechanic informed him that the entire subframe needed to be replaced to ensure safe driving. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 115,000.

Frame rusted through from the inside out. There isnt even any surface rust where the hole started. Its just a hole in the middle of clean metal. The rest of the frame rail is solid. Rear suspension arm mount is also rusted out and starting to come off. The entire structural integrity of the frame is in question, even though externally, theres only slight surface rust. The frame should not be rusting this way.

On August 7, 2018, the Office of Defects Investigation (ODI) received a defect petition from Mr. Gary Weinreich alleging premature frame corrosion failure in model year (MY) 2002 - 2006 Toyota 4Runner vehicles. The petitioner based his request upon a corrosion-related front suspension failure he experienced in his MY 2005 Toyota 4Runner, a class action lawsuit settlement involving other Toyota products, and other complaints of underbody corrosion in Toyota 4Runner vehicles that he found in NHTSA?s online complaint database. The petitioner submitted a complaint to NHTSA documenting his experience (NHTSA ID 11098055). On August 17, 2018, ODI opened DP18-002 to evaluate the petitioner?s request. ODI?s evaluation included information provided by the petitioner regarding his vehicle, facts related to the class action lawsuit cited by the petitioner, and consumer complaint data received by NHTSA regarding underbody corrosion in third and fourth-generation Toyota 4Runner vehicles.The undercarriage of the petitioner?s vehicle exhibited severe corrosion damage indicative of seawater immersion. The vehicle?s service history shows that concerns with underbody corrosion were first noted by a Toyota dealer in a multi-point vehicle inspection performed on April 28, 2011. The invoice for that inspection noted ?severe and excessive amount of rust on the undercarriage and on the drive shaft transmission.? Two years later, on October 21, 2013, another multi-point inspection by a Toyota dealer observed further progression of underbody corrosion damage, noting: ?rust on shocks/struts and other components,? ?rust on exhaust system,? ?both splash shields severely rusted,? and ?undercarriage very rusty.? On July 17, 2017, approximately 10 months prior to experiencing the suspension failure incident, an independent repair facility performing routine oil change and brake maintenance informed the Petitioner of a concern with ?excessive frame corrosion? on his vehicle. The service history, severe general corrosion damage, failure age, and environment do not support the petitioner?s allegation of premature corrosion failure.ODI?s analysis of NHTSA complaint data identified fifteen incidents of front lower control arm failure in fourth-generation Toyota 4Runner sport utility vehicles. Two of the failures, including the petitioner?s vehicle, involve vehicles operated in ocean front communities with continuous exposure to aerosolized marine salts and potential exposure to seawater immersion. The remaining thirteen failures all involved vehicles owned or previously registered in states with the greatest use of deicing salts to treat road surfaces in winter months (?Salt states?). On average, the front lower control arm failures occurred after 13.1 years in service in highly corrosive environments. The failure ages and environments do not support the petitioner?s allegation of premature corrosion failure. NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Since the information before the Agency is not indicative of a vehicle-based defect, it is unlikely that any investigation opened because of granting this petition would result in an order concerning the notification and remedy of a safety-related defect. Therefore, upon full consideration of the information presented in the petition and the potential risks to safety, the petition is denied. The denial of this petition does not foreclose the Agency from taking further action if warranted or the p
