2026–2027 Thomas Built Buses SAF-T-Liner HDX2: electrical system recall
A door that fails to open or close increases the risk of injury to occupants in a crash.
What was reported
Source: manufacturer filing, 49 CFR Part 573Reported to NHTSA Jun 26, 2026 by Daimler Trucks North America, LLC, owners notified Oct 14, 2026.
What that means, in plain English
Source: WhichTrim's reading of the filing above — not NHTSA's wordingA door that fails to open or close can trap occupants or impede egress in a crash, but the defect itself (a faulty relay preventing door operation) does not directly cause a crash or remove vehicle control, placing it at moderate rather than high severity.
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 fix, from the dealer bulletin
Source: NHTSA remedy instructions and dealer noticeRead from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign F1035). 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 26V408000Vehicles built from Jul 10, 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 →

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 F1035 the same recall as 26V408000?
Yes. F1035 is the number Daimler Trucks North America, LLC uses for this campaign in its own paperwork and in the letter it sends owners. 26V408000 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 Jul 10, 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. This campaign was filed without a repair available — Daimler Trucks North America, LLC says so in the text above, and expected one by October 2026.
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.
