Honda preliminary evaluation PE23005
Momentary Increased Steering Effort. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the steering on 2 model years (2022–2023). Opened Mar 17, 2023, closed Nov 30, 2023 after 8 months without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedOn March 17, 2023, The Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE23-005) to access the alleged defect of momentary increase in steering effort in model years (MY) 2022 and 2023 Honda Civic vehicles. The complaints report that the momentary increase in steering effort (described as "sticky steering") occurs mostly at highway speeds after driving for a certain amount of time. The reports have been received over the past 2 years with most occurring with low vehicle mileage. The steering gear contains a unit that includes a worm gear and a worm wheel. Honda stated this condition of momentary increase in steering effort occurs due to two factors within this unit. During manufacturing, the worm wheel goes through annealing and component conditioning processes. These processes caused internal stress and strain within the worm wheel. This strain was slowly released over the first few months of the vehicle life. Over time, the released strain caused the deformation of the teeth on the worm wheel, causing the worm gear to catch on the worm wheel. This results in the consumer’s momentary increased in steering effort. Also, the manufacturing process did not guarantee consistent grease application and therefore, some vehicles within the scope received too little grease which contributes to the momentary increase in steering effort. Analysis of all relevant data indicates that the subject condition occurs early in the vehicle’s life primarily in winter months. Additionally, the subject vehicles need to be driven in a straight line for a period of time, possibly until the vehicle is warmed up, to recreate the condition. The condition does not illuminate a malfunction indicator light (MIL). Some complaints allege Honda dealerships are unable to recreate the condition or state this is a normal vehicle operation. However, Honda released Service Bulletin 23-037 in July of 2023 which accurately describes the condition. To address this issue, Honda directs dealerships to remove the electronic power steering (EPS) gearbox and replace with a new gearbox. Further, Honda stated that the worst case steering effort from all warranty returned parts tested was 2.4 pounds. ODI complaint traffic remains steady. ODI has received 13 crashes to date, 11 of which allege roadway departure due to not being able to overcome the momentary increased steering effort prior to their vehicle leaving the roadway. The remaining 2 incidents claim overcorrection of the steering wheel. PE23-005 has been upgraded to an Engineering Analysis (EA23-003) to further assess the scope, frequency and potential safety related consequences of the momentary increase of steering effort. Further the scope has been expanded to include assessment of the Acura Integra and Honda CR-V models. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the resumes carrying the full reasoning are linked below.

These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.
What owners had already reported
Source: complaints on file the day it openedWhen NHTSA opened this on Mar 17, 2023, owners had filed 306 complaints with the agency about the model years above, of which 151 named the steering NHTSA went on to investigate. Owner complaints are the agency’s main early signal: ODI screens them, and a Preliminary Evaluation is usually where a pattern in them ends up.
This is what the complaint file held on that date, not a claim about which reports prompted the investigation — NHTSA’s complaint records carry no investigation number, so nobody can make that link from the data alone. The opening resume linked above names the reports ODI itself cited. Complaint records on this site begin with 2016.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE23005 a recall?
No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is PE23005 still open?
No. It closed on Nov 30, 2023 without a recall.
Which vehicles does PE23005 cover?
NHTSA opened it on 2 model years: 2023 Honda Civic, 2022 Honda Civic. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
