Reduced Power After Engine Stall
NHTSA Preliminary Evaluation PE24007 — closed, opened 2024-03-07 and involving the NISSAN NISSAN.
NHTSA investigation PE24007 is a Preliminary Evaluation opened on 2024-03-07 and currently closed. The subject of record is NISSAN NISSAN, which places this file inside the Office of Defects Investigation queue for NISSAN. Latest activity on this investigation was logged on 2025-10-02 — 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 PE24007 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 this investigation on March 7, 2024, after receiving twenty (20) consumer complaints and multiple field reports describing reduced power (limp mode) after re-starting the..." 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
The Office of Defects Investigation (ODI) opened this investigation on March 7, 2024, after receiving twenty (20) consumer complaints and multiple field reports describing reduced power (limp mode) after re-starting the vehicle following a stall on certain 2022-2024 model year (MY) Nissan Versa. A Preliminary Evaluation was opened to gather information and assess whether the subject vehicles contain a safety-related defect. During this investigation, Nissan explained that certain 2022-2044 MY Nissan Versa vehicles equipped with a manual transmission may, under specific conditions, experience a Malfunction Indicator Light (MIL) along with reduced engine performance following an engine start-up after a stall. In certain conditions, if the vehicle stalls and an engine restart occurs within five (5) seconds, the vehicle will enter a fail-safe mode with limited engine torque. The fail-safe mode helps prevent damage to the engine, a complete loss of motive power, and allows the driver to maintain control of the vehicle. ODI reviewed over 180 incidents where drivers described entering a limp mode following a vehicle re-start after having stalled the vehicle. Review of these incidents did not identify any alleged crashes, near crashes, or injuries. In all of the cases reviewed, the driver was able to drive the vehicle to a safe location. On April 28, 2025, Nissan released a Technical Service Bulletin NTB25-024 on certain MY 2022-2024 Versa vehicles equipped with a manual transmission. The remedy applies to subject vehicles built through July 9, 2024, and consists of replacing the Valve Timing Control (VTC) unit and installing updated control software. The bulletin will be implemented at no charge to the customer and includes all parts and labor. Subject vehicles built after July 9, 2024 were manufactured with these changes already in place. Following updates to the subject vehicles, ODI has not received any consumer complaints describing a limp mode condition on vehicles bu
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.
