2017 Porsche 911 and 1 other Porsche model: visibility recall
In the event of a crash, if the windshield separates from the vehicle, it can increase the risk of injury.
What was reported
Source: manufacturer filing, 49 CFR Part 573Reported to NHTSA Mar 2, 2017 by Porsche Cars North America, Inc, owners notified May 12, 2017.
What that means, in plain English
Source: WhichTrim's reading of the filing above — not NHTSA's wordingImproperly bonded windshield can detach in a crash, reducing occupant protection (structural integrity, ejection risk) and failing FMVSS 212, but the defect manifests only in a crash rather than causing one or constituting a fire/loss-of-control event.
Written for us by a language model from the manufacturer's filed text, which is quoted in full above. Where the two differ, the filing is the record and this is only our summary of it.

The advisory, as filed: “AH04 - Re-bonding Windshield (Stop Sale/Recall Campaign) Vehicle Type: 911 (991) Model Year: 2017.”
Read from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign AH04). The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.
Which vehicles are covered
Source: NHTSA campaign 17V135000Vehicles built Jan 10, 2017 to Jan 30, 2017 — a VIN outside that window is not part of this campaign even if the year, make and model match.
| Model year | Class | Safety Signal | Recalls on file |
|---|---|---|---|
| 2017 Porsche 911 | Coupe | C | 5 |
| 2017 Porsche Boxster | Convertible | D | 6 |
Those are the model years inside WhichTrim's range, 2016 onward. The campaign may cover others outside it, and the only thing that settles whether one specific vehicle is included is its VIN.
How much of it has been fixed
Source: manufacturer quarterly report, 49 CFR 573.7of the campaign
The final figure: the six quarters of reporting that 49 cfr 573.7 requires have closed.
This is the manufacturer's own cumulative count of vehicles it has inspected and repaired, divided by the vehicles the campaign covers. It files that count with NHTSA every quarter for six consecutive quarters, starting from the quarter in which owners were told a remedy was ready, and then the obligation ends — so a figure on an older campaign is where the count stopped, not where it stands today.
It rarely reaches 100%, and not because the work was not done. The same report asks manufacturers to count vehicles they could not reach at all — exported, stolen, scrapped, or simply never located — and those stay in the denominator. A low number means a lot of these vehicles are still out there unrepaired; it does not tell you which ones.
The federal paperwork

A recall applies to a build range, so year, make and model cannot settle it. Type the VIN and the WhichTrim recall report checks this campaign’s build window and engine against it.

Common questions
Source: NHTSA, 49 CFR Part 573Is AH04 the same recall as 17V135000?
Yes. AH04 is the number Porsche Cars North America, Inc uses for this campaign in its own paperwork and in the letter it sends owners. 17V135000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.
Does this recall repair cost anything?
No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.
How do I know whether my vehicle is included?
By VIN, not by model year. This campaign covers vehicles built Jan 10, 2017 to Jan 30, 2017. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.
What if the repair is not available yet?
It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.
What did the manufacturer say was wrong?
The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.
Who started this recall?
NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
