📋 Quick Snapshot
The CR-V at 100,000 miles is in mid-life if it has been maintained. This is the milestone where iridium plugs come due, the second CVT fluid change is required, and AWD components start to show their first wear. The 100K service is the difference between a CR-V that goes to 200K cheaply and one that becomes expensive after 130K.
✅ Essential at 100,000 miles (Toyota/Honda OEM schedule)
These are the items on the manufacturer service schedule at this milestone. Skip nothing here.
- Iridium spark plugs (full set of 4). Honda rates CR-V 1.5T and 2.4L iridium plugs at 100,000 mi. Gap to spec, use anti-seize sparingly.
- Second CVT fluid drain-and-fill (HCF-2). Even if the first was done at 60K. CR-V CVTs benefit from two close-spaced drain-and-fills over one flush.
- AWD rear differential fluid (DPF-II). Second change after the 60K change. Honda DPF-II only.
- Coolant flush (Honda Type 2). 90K-mile interval after the first 60K change.
- Brake pads (front and likely rear). Rears typically due between 90,000 and 120,000 mi.
- Brake fluid flush. Every 3 years.
- Inspect motor mounts. CR-V 1.5T side and torque-rod mounts soften by 100K. Vibration at idle is the tell.
- Drive belt. CR-V uses a single serpentine belt, rated to 100K.
- Cabin + engine air filters. Both due again.
🔬 Honda CR-V-Specific Items at 100,000 miles
Items specific to the Honda CR-V platform that generic service schedules miss.
- CR-V 1.5T GDI carbon cleaning. By 100,000 mi, intake valve carbon on the 1.5T is measurable. Walnut blasting or quality chemical decarbon noticeably improves throttle response and fuel economy. Symptoms: cold-start rough idle, slow throttle, MPG drop.
- CR-V CVT longevity reality. A CR-V CVT serviced every 30K-60K hits 200K easily. A neglected one often fails between 130K and 170K.
- CR-V 2.4L K24 valve clearance. Honda calls for valve clearance inspection at 100K on the 2.4L. Tight intakes lead to burned valves later.
- CR-V AWD pump on the rear diff. Inspect for leaks around the dual-pump rear diff. A leaky pump means AWD is unreliable and the next failure is expensive.
📝 OEM Service Intervals & 2026 Costs
Realistic 2026 pricing. DIY is parts only. Independent shop pricing includes parts and labor at a competent local shop. Dealer pricing typically runs 25-40% higher.

| Serpentine belt | 100,000 mi | $25-$50 | $130-$240 |
| Valve clearance inspect (2.4L) | 100,000 mi | Advanced DIY | $220-$420 |
| Full 100K service (dealer) | 100,000 mi | - | $1,700-$2,500 |
| Full 100K service (indie) | 100,000 mi | - | $1,200-$1,900 |
- Engine flush. Skip on a modern Honda.
- Transmission flush. Honda warns against flushing the CVT. Drain-and-fill only.
- Fuel system "induction service" packages at $250+. Same chemistry as $10 bottles.
- Timing belt replacement. CR-V uses a timing chain, no belt exists. Walk out of any shop quoting one.
