Frequently Asked Questions

Are these Freightliner M2 106 2021 complaints verified by NHTSA?
NHTSA collects complaints from owners but does NOT verify each one. The complaints below are unfiltered owner reports — useful for spotting patterns, but a single complaint doesn't prove a defect. Pay attention to: (1) volume of complaints on the same component, (2) consistency of described symptoms, and (3) whether NHTSA has opened a formal investigation or issued a recall on the same component. If a component appears in 5+% of complaints, that's usually a real pattern worth taking seriously.
Should I avoid buying a 2021 Freightliner M2 106 based on these complaints?
It depends on the components reported. 8 complaints across roughly tens of thousands of trucks of this model year is a light signal. Compare against other model years of the same truck — if 2022 has 3x more complaints than 2020 or 2024, that specific year has issues. Also check whether the most-reported component is something you can preventively address (e.g., DEF system issues can be mitigated with quality fluid + dealer software updates).
Have any of these complaints led to recalls on the 2021 Freightliner M2 106?
Not currently. Owner complaints don't automatically trigger recalls — NHTSA reviews complaint patterns and opens investigations when warranted. Recalls usually happen when a complaint pattern correlates with documented field failures or safety incidents. Even without recalls, repeated complaints on the same component is signal worth noting in your purchase decision.
How do I file my own complaint about a Freightliner truck?
Visit NHTSA.gov/file-complaint. You'll need: your VIN, the date of incident, description of what happened, and component affected (drivetrain, brakes, etc.). Filing takes ~10 minutes and adds your data point to the public record. This is the input that triggers NHTSA investigations. For commercial trucks, fleet operators reporting issues at scale (10+ similar reports) often accelerate NHTSA's review timeline.
What's the most expensive complaint pattern on the 2021 Freightliner M2 106?
Based on the complaint data: the top reported issue is 'POWER TRAIN' with 2 reports. Depending on the specific failure mode, this can range from a few hundred dollars (sensor replacement) to several thousand (transmission rebuild, DPF replacement, engine work). The complaint pattern alone won't tell you cost — check the symptoms described for hints about the actual root cause. Most commercial-truck complaints describe symptoms ($1,500–$5,000 repair range is typical), not catastrophic failures.
