# Peterbilt 348 Used Price & Common Problems | Big Rig Risk

> Peterbilt 348: used $39,900 to $179,950. Documented problems: EGR Valve. What to inspect before you buy.

**Verdict:** insufficient-data

Documented failure points and real market prices for the Peterbilt 348, sourced and dated. Note: no 348-specific failure documentation exists publicly; the risks below are drawn from a Kenworth T880 vocational-duty guide (a PACCAR-sibling vocational chassis) and are disclosed as a cross-model proxy, not confirmed 348-specific.

**Observed used price:** $39,900–$179,950

**Documented failure risks:**
- DPF System (vocational duty cycle): DPF clogs faster in stop-and-go vocational work, requiring forced regeneration cycles every 300-500 engine hours.
- Air Compressor / Air Dryer: Constant air usage for PTO operations, dump beds, and auxiliary equipment puts extra strain on the compressor and air dryer in vocational trucks.
- EGR Valve: EGR valve needs cleaning every 150,000 miles in dusty vocational environments or power and fuel economy suffer.
- Air Brake System / Air Compressor: Air compressor failures around 400,000 miles are common on hard-working vocational trucks due to heavy duty-cycle demand.
