Rear Suspension Control Arm Failure
NHTSA Engineering Analysis EA19002 — closed, opened 2019-07-29 and involving the NISSAN MAXIMA.
NHTSA investigation EA19002 is a Engineering Analysis opened on 2019-07-29 and currently closed. The subject of record is NISSAN MAXIMA, which places this file inside the Office of Defects Investigation queue for NISSAN. Latest activity on this investigation was logged on 2025-06-16 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA19002 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "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..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related NISSAN files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
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 potential safety consequence of a bushing failure. It was found the Vehicle Dynamic Control system allows the driver to maintain vehicle control in the event of a bushing failure. With between 7 to 13 years of field exposure, ODI is aware of only one low speed crash allegation describing minor contact with another vehicle’s trailer hitch. Nissan acknowledges that a crack can develop in affected control arms due to stress loading from normal use and that salts commonly used for roadway snow and ice treatment may result in corrosion that exacerbates the progression of the crack. Nissan implemented a design change in January of 2018 to improve the durability of the lower control arm. Affected vehicles have either been repaired with the countermeasure part under a customer satisfaction campaign
About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
