NHTSA defect investigations
Steering:Hydraulic Power Assist:Pump — Underhood fires closed
On September 6, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24024 to investigate allegations of engine compartment fires in model year 2021-2023 Jeep Wrangler and Gladiator vehicles. Most reports described fires starting on the front passenger side of the engine compartment while the vehicle was turned off, with several originating specifically at the electrohydraulic power steering pump's electrical connector. Following the opening of the investigation, ODI sent an information request letter to the vehicle manufacturer to assess the cause, scope, and frequency of the alleged defect. Additionally, ODI continued to receive reports of vehicle fires with a li

Engine — Loss of Motive Power open
The Office of Defects Investigation (ODI) has identified 68 Vehicle Owner Questionnaire (VOQ) reports for model years (MY) 2021 through 2024 Jeep Wrangler 4xe vehicles alleging a loss of motive power. Recall 22V-865 was issued by the manufacturer to address an engine shutdown condition in certain MY 2021-2023 Wrangler 4xe vehicles. The complaints noted here contain both post recall remedy failures and failures in vehicles not included within the scope of 22V-865. An analysis comparing complaints received before the issuance of recall 22V-865 and complaints outside the scope of the recall has been conducted.

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.

Whether any of this applies to one specific Wrangler
A campaign covers a build range, not a model year, so two identical-looking cars from 2021 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Jeep publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.
Hear about a recall before the letter does
The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2021 Jeep Wrangler, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
The contact owns a 2021 Jeep Wrangler 4XE. The contact stated that while driving at 75 MPH, the vehicle lost motive power rapidly and unexpectedly. The contact pulled over to the shoulder before the vehicle stalled. The contact returned to the contact's residence safely, and the vehicle was towed to the dealer the following day.
The contact owns a 2021 Jeep Wrangler 4XE. The contact stated while driving at an undisclosed, the check engine warning light illuminated. The accelerator pedal was depressed, but the vehicle failed to accelerate as intended, hesitated and jerked. The vehicle was taken to the dealer however, the failure could not be duplicated.
Purchased 1/3/2021. Steering wander, pulls to right, and 2' dead zone in steering wheel. Dead zone has no tire resistance in the steering wheel. Always a need to keep a tension on the wheel to prevent going to the right.
A car came into my son's lane. To avoid a head on collision, he veered right and went head on with a guardrail. Air bags did not deploy and the seatbelt did not lock. He was on hwy 1090. We find out tomorrow if the Jeep will be totaled because it has frame damage.
Only 500 miles on vehicle, went off-roading for the first time and within a short time after climbing a steep hill, smoke came from under vehicle and clutch went to floor and stayed. Turned Jeep off, pumped clutch which seemed fine but smoke continued for a minute.
I was driving in fog with ambient temperatures of approximately 9 degrees, windshield iced over approximately 2/3rds from the outside in with only the middle of the windshield clear, front defroster only was on maximum, with no air flow to anywhere else, but would not clear the windshield in front of the driver nor the passenger side.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by Jeep itself: 73 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 4 killed, 83 injured, as claimed, not verified — about 27 per 100,000 built. Every Wrangler model year, by year and system → Dated and by system, they are exhibit F of the defect dossier.
When owners reported it
miles, typically
Half the 121 owner reports with an odometer reading on file fall between 9,000 and 38,000 miles. That is when problems get reported, which is not the same as when they start — and not a failure rate, because nobody knows how many of these cars never had a problem at all.
Median mileage by component
| Component | Reports | Median miles | Vs same age |
|---|---|---|---|
| Electrical System | 34 | 29,400 | 1.05× |
| Engine | 29 | 26,200 | 0.52× |
| Steering | 24 | 20,000 | 0.8× |
| Power Train | 17 | 15,000 | 0.31× |
| Suspension | 16 | 19,000 | 0.59× |
Vs same age is this model year’s median for the system divided by the median of every 2021-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported earlier than same-age vehicles: engine (0.52×), power train (0.31×), suspension (0.59×). Which systems go early across the whole fleet: the component study.
Across 2018–2022 model years the Jeep Wrangler ranks 5 of 79 nameplates in the odometer-at-first-complaint study: owners reported problems at 0.31× the mileage of vehicles the same age (median 8,000 miles against a fleet 23,512).
Odometer readings as filed by owners with NHTSA. Readings under 100 or over 400,000 miles are dropped as data entry rather than history, and a component needs at least 12 readings before a median is shown for it.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.

Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

At the New York inspection station
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Jeep Wrangler failed the emissions check on 2.5% of first inspections — higher than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.0% (every 2021 vehicle: 1.5%).

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2021 vehicle” is every 2021 model-year car, SUV and pickup inspected in the same window, all makes. This is the state’s record of test results, not a reliability score by itself. Source: New York State Department of Motor Vehicles, Vehicle Inspections (data.ny.gov, Open NY terms).
Common questions about the 2021 Wrangler
Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Jeep Wrangler have any recalls?
NHTSA has posted 17 recall campaigns for the 2021 Jeep Wrangler, 6 of them rated critical. The most serious on file is 26V363000, covering Steering. 1 of them was filed with no repair available at the time — NHTSA's file records what the manufacturer had in hand on the filing date, not what exists today. There is an active park outside advisory — act on it before driving. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2021 Jeep Wrangler?
NHTSA has not published a crash-test rating for the 2021 Jeep Wrangler yet. On the recall record WhichTrim grades it F (22/100), which measures open and severe recalls rather than crash protection.
What is the fuel economy of the 2021 Jeep Wrangler?
Across the 12 EPA-rated configurations of the 2021 Jeep Wrangler, the best EPA combined figure is 25 mpg (MPGe on the electrified versions). Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2021 Jeep Wrangler?
Transport Canada measured it at 160.2–181.9 in long, 74.0 in wide (body, without mirrors), 73.6 in tall, on a 96.9–118.5 in wheelbase. Curb weight: 3,920–5,223 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2021 Jeep Wrangler?
Owners have filed 959 complaints with NHTSA about the 2021 Jeep Wrangler, most often about electrical system, steering, engine. Of those, 20 involved a crash, 27 a fire, 15 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2021 Jeep Wrangler?
The EPA smog rating for the 2021 Jeep Wrangler runs 1 to 7 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III LEV160, California LEV-III SULEV30, California LEV-III ULEV70, Federal Tier 3 Bin 160, Federal Tier 3 Bin 30, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2021 Jeep Wrangler?
The manufacturer has filed 1188 service bulletins and related communications with NHTSA for the 2021 Jeep Wrangler, most often covering electrical system, engine, equipment. The most recent is dated 2026-10-10. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.
How does the 2021 Jeep Wrangler do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Jeep Wrangler failed the emissions check on 2.5% of first inspections — higher than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.0% (every 2021 vehicle: 1.5%). The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.
What we hold, and what an empty row means
Paid vehicle-history reports will not tell you the difference between “nothing happened to this car” and “we never received that record” — both of the big two say as much in their own help pages. Most of what is on this page comes from complete federal registers, so we can tell you which is which, row by row.

| Fuel economy & configurations | 12 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | 12 configurations | EPA emission certificates | Smog rating, standard and the sales area that decides where the car can be sold new. |
| Recalls | 17 | NHTSA recall campaigns | A complete federal register: every campaign covering this model year, with severity and advisory flags. |
| Owner complaints | 959 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | 4 tested | NHTSA NCAP | Only the configurations NHTSA chose to crash-test, which is never all of them. |
| Service bulletins | 1188 | NHTSA manufacturer communications | Everything the manufacturer told its dealers about a defect or malfunction, short of a recall. |
| Investigations | 4 | NHTSA Office of Defects Investigation | Open and closed defect investigations, with the agency's own narrative. |
| Driver-assist crash reports | none | NHTSA Standing General Order 2021-01 | No report has been filed. Only entities named in the order report, and only crashes they hear of — so this is also what an unequipped car, or a manufacturer without telematics, looks like. |
| Specifications filed with NHTSA | 13 fields | NHTSA vPIC, decoded from VIN patterns | What the manufacturer filed under the federal VIN rule — a configuration, not the full trim ladder. |
| Measured dimensions | 7 fields | Transport Canada, Canadian Vehicle Specifications | Length, width, height, wheelbase, track and curb weight, measured on the North American versions. |
| Trims, pricing & equipment | none | Manufacturer press kit | We have not transcribed a press kit for this model year yet. This is our gap, not the manufacturer's — the one row here where an empty cell means we are behind. |

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.
