🔧 What’s Covered Under Hybrid Warranty – And What’s Not
One of the most common questions we get from hybrid owners is this:
“Is my hybrid battery still under warranty?”
It’s a fair question. With some batteries costing thousands to replace, knowing whether you’re covered can make all the difference. But hybrid component warranties vary wildly depending on brand, mileage, and age.
Let’s break it down clearly so you know where you stand—and what to do if something goes wrong.
🛡️ High-Voltage Battery Warranty Coverage
Most major car manufacturers offer separate, extended warranties for the high-voltage battery (the main hybrid power unit). Here’s a quick snapshot:
-
Toyota & Lexus hybrids:
Usually 8 years or 100,000 miles (whichever comes first). Optional battery health checks may extend coverage to 15 years in some cases. -
Honda hybrids:
5 to 8 years depending on the model. Recent models like the Jazz Hybrid or CR-V Hybrid offer up to 8 years, 100,000 miles. -
Kia & Hyundai hybrids:
Strong coverage—typically 7 years or 100,000 miles. -
BMW & Mercedes plug-in hybrids:
Around 6 to 8 years or 100,000 miles, though it’s worth confirming based on year and model. -
Nissan e-POWER and EVs:
8 years or 100,000 miles on battery degradation below a certain capacity threshold.
⚠️ What’s Not Covered
-
12V battery failures – These fall under regular warranty (1–3 years typically).
-
Damage from water ingress or accidents – Warranty usually doesn’t cover collision damage or flood faults.
-
DIY tampering or unapproved repairs – If the seal is broken on the battery or inverter by a non-certified tech, coverage is void.
-
Age/mileage exceeded – If the battery is older than 8 years or has gone past its mileage cap, you’re on your own.
📉 Battery Performance vs. Warranty Claims
Most manufacturers only approve a hybrid battery replacement if the capacity drops below a certain threshold (e.g., below 70%). A battery still functioning—just with reduced range—may not qualify unless it’s underperforming beyond limits.
🧰 What We Do When You’re Out of Warranty:
If your hybrid battery isn’t covered anymore, we offer:
-
High-voltage battery diagnostics
-
Replacement battery modules or packs
-
Battery balancing and reconditioning
-

✅ Tip: Always ask for a hybrid health report during every service. This keeps your warranty extended (Toyota, Lexus), and gives you documentation for future claims.
