NHTSA investigation PE22011 is a Preliminary Evaluation opened on 2022-11-28 and currently closed. The subject of record is HONDA HONDA, which places this file inside the Office of Defects Investigation queue for HONDA. Latest activity on this investigation was logged on 2024-07-22 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

A Preliminary Evaluation like PE22011 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.

Investigators summarized the matter as follows: "On November 29, 2022, the Office of Defects Investigation (ODI) opened PE 22-011 after reviewing field reports alleging rear differential seizure in 2018-2022MY Honda CR-V and HR-V vehicles equipped with all wheel drive...." 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 HONDA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

On November 29, 2022, the Office of Defects Investigation (ODI) opened PE 22-011 after reviewing field reports alleging rear differential seizure in 2018-2022MY Honda CR-V and HR-V vehicles equipped with all wheel drive. To date, ODI has not received any consumer complaints. Some of the field reports received alleged the vehicle’s wheels locked up with no warning while the vehicle was in motion. These vehicles were towed to a dealership. Examination of these vehicles showed the driveshaft had broken and the differential unit was completely damaged. The field reports cited a lack of oil due to damaged oil seals as the cause. Honda provided data including consumer complaints, field reports, and warranty claims they received relating to the loss of oil retention and resulting differential damage. Honda’s data cited 1201 incidents with unique vehicle identification numbers (VINs). The rear differential oil seals prevent the oil from leaking out and protect internal components from contaminants. A loss of oil lubrication results in failure of the vehicle differential. Honda stated that the oil seal’s lip contact with the driveshaft may become unstable due to intermittent changes in internal pressure. Their review of field report and warranty data indicated that these failures occurred early in the vehicle’s life thus the failures were covered by the manufacturer’s warranty. Honda stated that in November 2021 they changed the seal specifications and improved the packaging process of the parts for transport. Honda also enacted an enhanced visual inspection process both before and after the oil seal installation on the assembly line. Honda stated that in the event of differential failure, the operator can control the vehicle without stability loss. After the drive shafts break due to differential failure, the operator will hear noises and the vehicle will still function as a 2WD vehicle preventing complete loss of motive power. Based on the following factors, ODI is closing

About This Investigation Type

A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
