CHECK IT CLOSE
specific things to inspect and negotiate

What goes wrong

Diesel models with the CP4 high-pressure pump have a documented failure mode where the pump disintegrates and seeds metal through the entire fuel system. Rare, but catastrophic when it happens. Gas models are exempt.

Federal record for the 2014 Volkswagen Jetta, pulled from NHTSA when this page was built:
386 owner complaints on file , most-reported: ELECTRICAL SYSTEM (81) · POWER TRAIN (70) · ENGINE (57).
5 safety recalls listed.
Complaint volume tracks how many were sold as well as how they held up , read it as a pattern, not a score. Counts change; confirm live at nhtsa.gov or by running the free check below.
Rough cost: $6,000-$9,000 full fuel system if the pump grenades. Broad estimates , labor rates and parts vary widely by region and shop.

What to do about it

Before you hand over cash: TDI only: ask if the pump was ever replaced and whether the car has run anything but good diesel. Any fuel-system metal history = walk.

Whatever you find, a $100-150 pre-purchase inspection by an independent mechanic is the cheapest money you’ll spend on any used car , including this one.
