NHTSA defect investigations
Electrical System:Propulsion System — Pedestrian alert sounds closed
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021. On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject mat

Whether any of this applies to one specific Cayenne
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. Porsche 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 Porsche Cayenne, 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.
On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure.
The contact owns a 2021 Porsche Cayenne. The contact stated that while driving at various speeds, the front driver's side seat belt independently tightened and loosened. The emergency light illuminated, and a seat belt warning chime sounded continuously.
Over approximately the past month, the leather covering on the dashboard of my 2021 Porsche Cayenne has rapidly begun lifting, buckling, and separating across a substantial portion of the dashboard. The deformation has become increasingly pronounced in a short period of time despite normal use and careful maintenance of the vehicle.
Battery completely discharged and the safety switch in the battery malfunctions and battery can not be charged again. There are many complaints seen online about the battery problems Porsche has. This strands the car and me the driver. The dealer and independent mechanics said the same.
Vehicle Information: 2021 Porsche Cayenne E-Hybrid (VIN: ) Description of Defect: While operating the vehicle, the steering column bolt physically backed out and detached, causing an immediate, complete loss of steering control.
when decelerating and car is in gear 2 it lurches the car forward while braking, basically fighting the attempt to slow the car down. I attribute this to aggressive downshifting, but is a safety issue because the operator then needs to compensate by pressing down on the brake pedal harder to stop the car.

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.
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 Porsche Cayenne failed the emissions check on 1.8% of first inspections — close to the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.1% (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).
Cayenne by model year
all years, side by side →Common questions about the 2021 Cayenne
Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Porsche Cayenne have any recalls?
NHTSA has posted 7 recall campaigns for the 2021 Porsche Cayenne, 2 of them rated critical. The most serious on file is 23V841000, covering Electrical System. 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. The manufacturer's own estimate for when a fix would be ready: mid-2024. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2021 Porsche Cayenne?
NHTSA has not published a crash-test rating for the 2021 Porsche Cayenne yet. On the recall record WhichTrim grades it F (52/100), which measures open and severe recalls rather than crash protection.
What is the fuel economy of the 2021 Porsche Cayenne?
Across the 12 EPA-rated configurations of the 2021 Porsche Cayenne, the best EPA combined figure is 21 mpg (MPGe on the electrified versions). Figures are the EPA's own, per configuration, and every one is listed above.
What do owners complain about on the 2021 Porsche Cayenne?
Owners have filed 21 complaints with NHTSA about the 2021 Porsche Cayenne, most often about electrical system, unspecified, air bags. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2021 Porsche Cayenne?
The EPA smog rating for the 2021 Porsche Cayenne runs 3 to 5 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 ULEV125, California LEV-III ULEV70, Federal Tier 3 Bin 125, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2021 Porsche Cayenne?
The manufacturer has filed 3186 service bulletins and related communications with NHTSA for the 2021 Porsche Cayenne, most often covering electrical system, engine, unknown or other. The most recent is dated 2026-09-24. 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 Porsche Cayenne do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Porsche Cayenne failed the emissions check on 1.8% of first inspections — close to the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 1.1% (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.

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.
EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly. Trim-level specifications and pricing are transcribed from the manufacturer's official press kit; every value carries its source in the data file.
