Jeep Cherokee — what actually breaks, by engine

2015–2020 · 6,484 federal complaints · 2 engines

Reliability ratings usually stop at the model. But two Cherokees with different engines can fail in completely different ways — and the engine is a choice you make at purchase. Here is what owners actually complained about, separated by engine.

Ownership profile

Each axis is this model's percentile within its own segment — comparing a pickup's fuel economy against a compact car's would say nothing. Built from EPA test data.

Purchase price is not included: no free, licensed source publishes MSRP or transaction prices, so a value-for-money score would have to be invented. We would rather show one axis fewer.

What each engine's complaints are about

Share of component mentions. One complaint can name several components, so these describe what an engine's complaints are about — they are not a failure rate.

Diagrams show cylinder layout and displacement from the decoded VIN data. Forced induction is marked only where the engine designation states it or the specific output leaves no doubt.

Method, sources and limitations

How this was built

  1. Source: NHTSA public complaint database (api.nhtsa.gov), retrieved 2026-08-16. Every complaint carries the first 11 characters of the vehicle's VIN.
  2. Those partial VINs were decoded through NHTSA's vPIC service to identify the exact engine — 97.2% resolved successfully. This is how the data gets to engine level; model-level ratings cannot do this.
  3. Percentages are the share of component mentions, not of complaints. One complaint can name several components, so the figures describe what a given engine's complaints are about — they do not sum to a failure rate.

What this does not tell you

  • This is not a reliability ranking. Complaint totals track how many were sold, not how often they fail. Nobody publishes per-engine sales volume, so comparing totals between engines would be misleading. Read each engine's own breakdown; don't race them against each other.
  • Engines with fewer than 50 complaints are omitted — too small to say anything honest about.
  • Complaints are self-reported by owners. They skew toward problems that are alarming or expensive, and toward vehicles under active recall attention.

We never sell your information to dealers.
