Composite analysis from NHTSA recall, complaint, and crash data
- ▸Brake system recall
- ▸Fuel system recall
- ▸2 complaint(s) involved a fire
- ⚠4 recalls on same component: Electrical
- ⚠2 recalls on same component: Engine/Powertrain
- ⚠2 recalls on same component: Brakes
- ⚠Safety system appears in both official recalls and owner complaints
Lemon law eligibility depends on state law, number of repair attempts, and days out of service. Consult an attorney for actual eligibility.
The same components appear in both official NHTSA recalls and owner-filed complaints — a double-confirmed failure signal.
Deferred Failure Risk
Vehicle-specific risks from this model-year's complaint record, known defects, and service milestones
Owners of the 2015 KENWORTH T680 report engine/powertrain issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.

Component Failure Cascade Risk
Known patterns where one defect leads to more severe downstream failures
▸ Engine stalling at speed — fuel delivery failure can cause sudden loss of power in traffic or on highways
▸ Loss of brake assist and ABS in emergency — can significantly extend stopping distances
Complaint & Reliability Timeline
Annual complaints (blue) vs. composite reliability score (amber) — recall years marked in red
The blue line shows 8 NHTSA complaints on file for the KENWORTH T680 — a relatively low volume that spans from 2018 to 2022.
The amber reliability line averaged 98/100 across the vehicle's life — relatively stable, with the lowest point of 91/100 in 2021.
The recalls (red dashed lines) were issued in the same year or before complaints peaked, suggesting the manufacturer identified and acted on the defect relatively quickly.
Red dots on the amber line flag 2021, a year when complaints included crash events — these are the highest-severity incidents in the dataset.
