What Mileage Do Most Owners Replace an Engine At?
The table below uses completed engine orders (2020–2025) with odometer recorded at checkout. Figures describe **when people buy**, not a factory failure mileage.
| Odometer at purchase | Share of sales |
|----------------------|----------------|
| Under 100,000 mi | 19% |
| 100,000–149,999 mi | **31%** (largest band) |
| 150,000–199,999 mi | 28% |
| 200,000–249,999 mi | 13% |
| 250,000 mi and above | 10% |
**Plain-language takeaway:** About **three in ten** engine purchases happen between **100k and 150k miles**. Another **28%** occur between **150k and 200k**. Roughly **one in five** buyers order below **100k** — often crossovers, known problem years, or catastrophic failure.

How Does Vehicle Type Change Replacement Mileage?
Crossovers and compact SU
Vs tend to get engines earlier. Older trucks and work vehicles run higher odometer readings before replacement.
| Vehicle type | Example models | Median purchase mi (approx.) | Typical pattern |
|--------------|----------------|------------------------------|-----------------|
| **Compact crossover** | Equinox, Terrain, Escape | **124k–132k** | **47–49%** of Equinox/Terrain sales at 100–150k |
| **Half-ton pickup** | F-150, Silverado 1500, Ram 1500 | **158k–190k** | Mix of reman (newer MY) and used (older MY) |
| **Full-size SUV** | Tahoe, Yukon, Suburban | **188k–200k** | Often high-mileage used or reman |
| **Sedan** | Sonata, Fusion, Malibu | **120k–133k** | Many purchases under 150k |
| **Jeep / compact SUV** | Wrangler, Grand Cherokee | **130k–145k** | Blend of 100–150k and 150–200k |
Why do crossovers replace earlier?
Applications like the **2013
Chevrolet Equinox** and **GMC Terrain** show tight clusters around **120k–140k miles** in order data. Four-cylinder engines in daily-driver SUVs see steady load, timing-chain wear, oil consumption, and cooling-system stress. When internal repair exceeds reman value, owners replace sooner than truck fleets that defer longer.
Why do older trucks wait longer?
**2005–2007 Silverado and Ram 1500** orders often show **175k–220k+ miles** at purchase. A large share of these sales are **used engines** (see below), chosen when the vehicle’s book value supports a lower-cost swap rather than a full reman rebuild.
**Volume peak:** **2012–2014** model years — especially **2013 Dodge Ram 1500**, **2013 Chevrolet Equinox**, and **2012–2014 Ram** — account for the highest engine order counts. At purchase, those vehicles were typically **8–11 years old** with **130k–160k miles**.

Reman vs Used: Who Buys What at Which Mileage?
Condition mix strongly follows vehicle age and application.
| Condition | Share of engine sales (approx.) | Median purchase mi | Median vehicle age |
|-----------|----------------------------------|-------------------:|-------------------:|
| **Remanufactured** | 4,906 orders (~31%) | **160,000 mi** | **14 years** |
| **Used** | 9,392 orders (~59%) | **144,000 mi** | **11 years** |
**Pattern in the data:**
| Application profile | Typical choice | Example from sales mix |
|---------------------|----------------|----------------------|
| **2012–2015 Ram / Equinox** | **80%+ reman** | Newer MY, owner wants warranty-backed unit |
| **2004–2007 Silverado / Ram** | **50–74% used** | Higher mileage, lower vehicle value |
| **2005 Dodge Ram 1500** | **74% used** | Median purchase near **168k mi** |
Reman buyers skew **older and higher mileage** on average because reman is more common on vehicles kept long enough to need a quality rebuild. Used engines dominate total **volume** but see **far fewer warranty filings** per order — different expectations and coverage rules apply.
What Mileage Do Top-Selling Engines Hit Before Replacement?
Purchase-mileage percentiles from the most-ordered applications (odometer at time of sale).
Trucks (high volume)
| Year · Make · Model | Sales | P25 | Median | P75 | Vehicle age at sale |
|---------------------|------:|----:|-------:|----:|--------------------:|
| 2013 Dodge Ram 1500 | 112 | 127k | **158k** | 183k | 9 yr |
| 2014 Dodge Ram 1500 | 96 | 126k | **158k** | 191k | 9 yr |
| 2012 Dodge Ram 1500 | 93 | 129k | **153k** | 180k | 10 yr |
| 2013 Ford F-150 | 59 | 130k | **174k** | 216k | 10 yr |
| 2007 Chevrolet Silverado 1500 | 68 | 150k | **182k** | 227k | 14 yr |
Crossovers (earlier replacement)
| Year · Make · Model | Sales | P25 | Median | P75 | Vehicle age at sale |
|---------------------|------:|----:|-------:|----:|--------------------:|
| 2013 Chevrolet Equinox | 69 | 101k | **124k** | 141k | 9 yr |
| 2015 Chevrolet Equinox | 52 | 105k | **124k** | 155k | 8 yr |
| 2012 Chevrolet Equinox | 48 | 108k | **136k** | 161k | 10 yr |
| 2013 GMC Terrain | 37 | — | **142k** | — | 10 yr |
**Under 100k engine purchases** — most common YMMs: **2013 Equinox**, **2017 Equinox**, **2011 Jeep Wrangler**, **2013 Dodge Ram 1500**, **2014 Ford Escape**. Early replacement is a real segment (~19% of sales), not an edge case.

What Do Make-Level Patterns Show?
| Make (engine sales, 500+ orders) | Median purchase mi | Median age at purchase |
|----------------------------------|-------------------:|-----------------------:|
| Toyota | **180,000** | 14 yr |
| GMC | 160,000 | 13 yr |
| Chevrolet | 158,080 | 12 yr |
| Dodge | 157,287 | 12 yr |
| Ford | 155,000 | 12 yr |
| Jeep | 139,982 | 13 yr |
| Hyundai | **124,707** | 9 yr |
Toyota owners in this dataset tend to **wait the longest** before ordering an engine. Hyundai owners replace **earlier in miles and vehicle age** — consistent with crossover-heavy mix and specific model-year applications.
Vehicle **age** and **mileage** correlate weakly (*r* ≈ 0.16 for engines): compare your odometer to **your year and body style**, not a single national average.

When Should You Shop Earlier Than “Average”?
Median purchase mileage is a **market snapshot**, not a rule for when your engine will fail.
Before You Buy a Replacement Engine: Quick Checklist
| Step | Action |
|------|--------|
| 1 | Confirm **exact YMM, engine size, and VIN** match the unit ordered |
| 2 | Decide **reman vs used** based on age, budget, and warranty needs |
| 3 | Record **odometer photo** for activation and future claims |
| 4 | Plan **oil prime, break-in, and correct oil spec** before first start |
| 5 | Verify **timing components, sensors, and harness** transfer or replace |
| 6 | Keep **install invoice, fluid receipts, and scan reports** |
For reman coverage timing, mirror transmission rules where applicable and read required documents for a warranty claim: /blog/documents-required-warranty-claim.

What Should You Document If Problems Start Soon After Install?
Warranty data shows many engine complaints within the **first few hundred miles** — often oil leaks, knock, no-start, or misfire tied to **prime, timing, fuel, or gaskets** — not because the vehicle was “too new” for an engine swap.
Before contacting support:
Odometer photos at delivery and at symptom onset
Scan report (all codes, freeze frame if available)
Proof of oil prime and break-in procedure
Install invoice with date, shop, and parts noted
Photos of leaks **before** cleanup
> Before any unit is removed or replaced under warranty, document the symptom, save scan results or inspection notes, and contact support with the installation details so the issue can be reviewed accurately.

FAQ
Is 150,000 miles normal for an engine replacement?
Yes. In this sales dataset, **150,000 miles** is the median purchase odometer for replacement engines. About half of buyers ordered at or below that figure.
Do SUV owners replace engines earlier than truck owners?
Generally, yes. **Crossovers** (Equinox, Terrain, Escape) cluster around **120k–140k miles** in order data. **Half-ton and older trucks** more often appear between **170k and 220k+ miles**.
Should I buy reman or used at high mileage?
**Reman** is more common on **2012–2015** applications and when owners want warranty-backed quality. **Used** dominates **2004–2007** truck orders above **175k miles**, where vehicle value supports a lower-cost swap. Compare coverage in used vs reman expectations: /blog/used-vs-reman-expectations-before-purchase.
Does buying an engine under 100,000 miles mean something failed early?
Not always. About **19%** of engine sales in this data are under **100k miles**. Causes range from catastrophic failure and neglected maintenance to known design issues — verify root cause with compression, leak-down, and oil analysis before ordering.
How does engine replacement mileage compare to transmission replacement?
In the same order dataset, **transmissions** median near **153,000 miles** and **engines** near **150,000 miles** — similar overall. **Crossovers** replace both components on the early side; **older trucks** run higher on both. See the companion guide: at what mileage do customers replace a transmission: /blog/at-what-mileage-do-customers-replace-a-transmission.
