LATCHES/LOCKS/LINKAGES:HOOD:LATCH
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.
AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE, AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
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 subst…

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
NHTSA received a defect petition (DP19-001) from the Center for Auto Safety (CAS) on March 21, 2019 alleging that the Automatic Emergency Braking (AEB) system on Model Year (MY) 2017-2018 Nissan Rogue and Rogue Sport vehicles was engaging in cases where there was no obstruction in the path of the vehicle. The CAS petition additionally alleges that, based on Nissan's actions, the manufacturer is aware of the issue due to issuing a Technical Service Bulletin (TSB) launching two "Quality Actions," and initiating a "Customer Service Initiative" in relation to it. CAS contends that Nissan's actions do not represent an adequate long-term solution to the problem, as the action is only available du…
What the investigation types mean
- Preliminary Evaluation (PE) — an initial investigation of a possible safety defect.
- Engineering Analysis (EA) — an escalation from a PE, involving deeper technical assessment.
- Recall Query (RQ) — NHTSA examining an existing recall: usually whether its scope is wide enough, or whether the remedy actually worked.
- Audit Query (AQ) — a review of how a manufacturer carried out a recall or reported information.
How to use this page
- Match the model, year, engine and equipment to the case scope. Read NHTSA's current case documents for details beyond the short summary shown here.
- Check the VIN separately for open recalls. NHTSA's VIN recall result does not list investigations — see how to check a specific car.
- Read the model-year report for the fuller picture: complaints, recalls and manufacturer communications together say more than any one of them alone.
- Give the mechanic the case number and ask whether the inspection can assess the reported symptoms. Request service records for any related work.
Limitations
Investigation status can change between imports. The vehicles and years listed are the part of each case covered by CarTold's database; the full case may include others. These counts describe cases and tracked models, not the number of vehicles with a fault. Check NHTSA's case search for the latest documents and status.
