2018 Freightliner M2 106 DD8 — Should You Buy One?
Typical asking price: $35,000–$60,000. There are 3 high-severity known issues you need to know before handing over a check.
Kestrel Take
The Freightliner M2 106 is the most common medium-duty truck in North America. The Detroit DD8 is a durable engine with solid reliability when maintained. These trucks do serious work — box trucks, dump trucks, wreckers — and the upfit condition is as important as the chassis.
What we checked
No public record to reconcile against
We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
Known Issues for the 2018 Freightliner M2 106 DD8
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
The DD8 emissions system has the same derate risks as larger Detroit engines. Pre-purchase ECM scan mandatory.
Repair cost (estimate): $500-$3,000
Source: not yet checked against public records.
The Allison automatic paired with the DD8 is an excellent transmission but requires fluid service every 50,000-75,000 miles. Skipped service shortens Allison life significantly.
Repair cost (estimate): $400-$800 service, $4,000-$8,000 rebuild
Source: not yet checked against public records.
Air brake systems require annual DOT inspection. Verify the truck has current inspection stickers and no leaks. A hissing sound when parked with brakes set is a red flag.
Repair cost (estimate): $200-$1,500 depending on what's needed
Source: not yet checked against public records.
