NHTSA Preliminary Evaluation PE22009 — closed, opened 2022-07-22 and involving the JEEP JEEP.
NHTSA investigation PE22009 is a Preliminary Evaluation opened on 2022-07-22 and currently closed. The subject of record is JEEP JEEP, which places this file inside the Office of Defects Investigation queue for JEEP. Latest activity on this investigation was logged on 2023-10-29 — 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 PE22009 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: "The Office of Defects Investigation (ODI) opened investigation PE22-009 after having received 80 complaints on model years 2014-2020 Jeep Cherokees alleging the Electronic Parking Brake (EPB) inadvertently activated whil..." 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 JEEP files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
The Office of Defects Investigation (ODI) opened investigation PE22-009 after having received 80 complaints on model years 2014-2020 Jeep Cherokees alleging the Electronic Parking Brake (EPB) inadvertently activated while the vehicle was in motion. During this investigation, the subject vehicles were updated to include only Model Years (MY) 2014-2016, while MY 2017-2020 were considered peers. Based on related repair invoices, ODI believed the EPB module was damaged by water leaking into the vehicle. When the EPB inadvertently activates, it can cause a stalling condition bringing the vehicle to a stop. ODI was aware of recall 15V-393 that addresses water ingress affecting the power liftgate module on nearly the same population of vehicles subject of this investigation. The liftgate module can potentially catch fire as a result of the water damage. Both the liftgate and EPB modules are located in a similar area of the vehicle. On May 11, 2016, the manufacturer released a Technical Service Bulleting (ODI #10191415, FCA #08-060-16) that instructs dealers on replacing the EPB module and inspecting the electrical connector for corrosion if a customer describes having the EPB not releasing. This Preliminary Evaluation was opened to assess the scope, frequency, and safety-related consequences of the alleged defect. On September 8 th , 2022, ODI sent an information request letter to Fiat Chrysler US LLC (FCA) requesting pertinent information on the subject 2014-2016 Jeep Cherokee and Peer 2017-2020 Jeep Cherokee vehicles. FCA Provided its full response on October 27 th , 2022 after ODI granted a one-week extension. ODI has reviewed the information FCA provided as well as new reports submitted to NHTSA’s Vehicle Owner Questionnaire database. Based on a review of all available information, ODI has identified evidence supporting a total of 1,655 subject vehicles that likely experienced a failure of the subject EPB. Within the subject vehicle complaints, ODI identified the 2014
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.
