Rear Suspension Control Arm Failure
On July 29, 2019, the Office of Defects Investigation (ODI) opened EA19002 to investigate instances of alleged rear lower control arm failures in 2013-2018 Nissan Altima and 2016-2018 Nissan Maxima vehicles. At the time the investigation was opened ODI had 91 consumer complaints alleging rear lower control arm failures in the subject vehicles.ODI was concerned about these complaints because many of them alleged an increased steering effort or loss of vehicle control.At the time these complaints were received, ODI was also aware of a proactive service campaign addressing 2013 Nissan Altima in salt-belt states for a similar concern. Since opening the investigation, ODI has confirmed, based on consumer complaints, warranty data, and testing conducted by Nissan and ODI, that owners of the subject vehicles are experiencing a corroded bushing at one of three mounting points of the control arm to the rear subframe.ODI has also confirmed that drivers become aware of the problem because of sound and abnormal vibrations. In addition, the failure mileage is typically over 113,000 miles at the time of failure.In conjunction with Nissan and VRTC, ODI participated in testing to assess the potent
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators us
Rear Suspension Control Arm Failure
PE18-013 was opened on December 1, 2018, with 4 complaints to ODI alleging incidents of the lower control arm fracturing at a connection point to the vehicle chassis due to corrosion. ODI has received an additional 87 complaints since the PE was opened. During PE18-013, Nissan indicated model years 2013-2018 shared a common rear lower control arm design. Nissan provided complaint and warranty data regarding 48 incidents of the subject failure. The majority of the complaints are from vehicles registered in salt belt states. There have been no crashes, injuries, or fatalities confirmed as of this date. Nissan advised that it has conducted testing to assess safety risk. Nissan states that due to low incident rate, high detectability, and low risk of adverse vehicle dynamics, it does not believe the subject lower control arm failure poses an unreasonable risk to motor vehicle safety.This preliminary evaluation has been upgraded to Engineering Analysis (EA) 19-002. During the EA, ODI will continue to collect and analyze complaint and field data in its efforts to fully assess the scope and frequency of the alleged defect. More importantly, ODI will also seek additional information and da
Hertz/Vehicles Rented with Open Recalls
NHTSA is opening this audit query to investigate whether The Hertz Corporation (Hertz) has complied with the requirements of the National Traffic and Motor Vehicle Safety Act (Safety Act). The Safety Act requires, among other things, that a rental company shall not rent a vehicle subject to a safety recall unless the recall remedy has been performed. 49 U.S.C. § 30120(i).NHTSA is in receipt of information that indicates Hertz rented vehicles to customers without having performed required recall repairs. Accordingly, we are opening this audit query to seek additional information concerning this issue.
Complete loss of motive power due to engine failure
On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 vehicles. At that time, ODI had received 6 Vehicle Owner Questionnaires (VOQ) and multiple early warning reports, with consumers reporting engine knocking noises accompanied by a loss of engine power while driving. The investigation identified bearing failures in certain vehicles equipped with the subject 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. ODI also identified early warning reports describing thermal incidents that occurred immediately after the vehicle suffered a catastrophic engine failure. The failures were the result of a manufacturing defect in specific engine bearings (main, A-, C-, and L-link) or other engine components that may cause engine damage and potentially lead to engine failure. Engine failure can result in a loss of motive power event that can increase the risk of a crash. Engine failure might also result in a fire if internal components detach and impact the e
About NHTSA Investigations
NHTSA investigations include Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), and Audit Queries (AQ). Investigations may lead to recalls if defects are confirmed. An open investigation means NHTSA is actively examining the issue.
