Problem Altec Industries, Inc. (Altec) is recalling certain 2024-2026 AT Series vehicles. The turntable rotation bearing fasteners may not have been heat treated properly. Risk A fastener that has not been heat treated could fail, resulting in separation of the pedestal and turntable, increasing the risk of injury. Fix Altec will instruct owners to inspect the lot number on the fasteners and, if necessary, order a rotation bolt kit to replace the fasteners, or schedule service with Altec, free of charge. Owner notification letters were mailed September 11, 2026. Owners may contact Altec customer service at 1-877-462-5832. Altec's number for this recall is CSN-3347.

Reported to NHTSA Jul 17, 2026 by Altec Industries, Inc, owners notified Sep 11, 2026.

What that means, in plain English

Source: WhichTrim's reading of the filing above — not NHTSA's wording

Fastener failure could cause separation of the pedestal and turntable on an aerial work platform, a structural failure that endangers occupants and bystanders, but no stop-drive order was issued and the filing is hedged ('could fail'), placing this below critical.

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.

Which vehicles are covered

Source: NHTSA campaign 26V463000

Vehicles built from Feb 1, 2025 onward — a VIN outside that window is not part of this campaign even if the year, make and model match.

None of the vehicles this campaign names has a page on WhichTrim: the catalogue covers the cars, trucks and SUVs the EPA certifies from 2016 on, and these vehicles fall outside it — older model years, or motorhomes, trailers, buses, motorcycles and chassis cabs the EPA does not rate. The campaign record above is complete as filed, and whether one specific vehicle is included is settled by its VIN. Other campaigns on vehicles without a page here →

How much of it has been fixed

of the campaign

One quarter into a six-quarter reporting window — early, and expected to climb.

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.

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 573

Is CSN-3347 the same recall as 26V463000?

Yes. CSN-3347 is the number Altec Industries, Inc uses for this campaign in its own paperwork and in the letter it sends owners. 26V463000 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 from Feb 1, 2025 onward. 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.
