If you’re looking at a Cadillac LYRIQ, new or used, the **battery warranty details** are just as important as the styling and range. The high‑voltage pack is the most expensive component in the vehicle, and understanding exactly how Cadillac backs it can save you from nasty surprises down the road.
Key takeaway
Cadillac LYRIQ battery warranty: the basics
Cadillac structures LYRIQ coverage the same way GM handles its other modern EVs: a **bumper‑to‑bumper warranty**, a **powertrain warranty**, and then a **separate EV propulsion battery warranty**. For most U.S. buyers, you’ll see language along these lines in the warranty booklet or window sticker:
- Basic (bumper‑to‑bumper) limited warranty: typically 4 years/50,000 miles for Cadillac passenger vehicles
- Powertrain limited warranty: typically 6 years/70,000 miles for Cadillac (model‑year and region dependent)
- Electric Vehicle Propulsion Battery Limited Warranty: **8 years/100,000 miles** on the high‑voltage pack and internal components
Region matters
What that means in plain English: **for the first 8 years or 100,000 miles after the LYRIQ is put into service**, Cadillac will repair or replace the propulsion battery (or its internal modules) if it fails due to defects in materials or workmanship, subject to the usual exclusions in the warranty booklet.
How long the LYRIQ battery warranty lasts (years & miles)
Cadillac LYRIQ warranty at a glance
The **start date** for all three warranties is the LYRIQ’s original in‑service date, usually the day it was first sold or leased to its first retail customer. From there, two clocks start ticking for the battery:
- **Time limit:** coverage ends 8 years from the in‑service date, even if the vehicle has low miles.
- **Mileage limit:** coverage ends once the odometer hits 100,000 miles, even if that happens before 8 years.
Quick rule of thumb
There’s no separate "sub‑warranty" for specific cells or modules, **the entire high‑voltage pack and its internal components are covered under the same 8‑year/100,000‑mile umbrella**. Cadillac (through your dealer) decides whether to repair individual modules or replace the entire pack when there’s a covered failure.
Does the LYRIQ battery warranty cover capacity loss?
Over time, every EV battery loses some usable capacity. The question buyers always ask is: **“Will Cadillac fix my LYRIQ battery if range drops too much?”** For GM’s modern EVs, the answer is usually **yes, up to a point**, but the exact threshold is buried in the fine print and can differ slightly by model.
While Cadillac’s public marketing emphasizes the **8‑year/100,000‑mile coverage** for defects, GM guidance for other Ultium‑based EVs (like Hummer EV and Sierra EV) spells out a **capacity‑retention guarantee around 70–75% of original usable capacity** during the warranty period. In practice, LYRIQ owners can expect a similar structure:
- Normal, gradual battery degradation is expected and not considered a defect by itself.
- If the **usable capacity falls below a defined threshold** (typically around 70–75% of original) within 8 years/100,000 miles, and it’s not due to misuse or damage, GM may repair or replace the pack or modules under warranty.
- Capacity is verified using **dealer diagnostic tools**, not just the in‑car range estimate, which can fluctuate with driving style and weather.
Check the exact language
Even if the capacity guarantee feels abstract, the practical takeaway is simple: **if your LYRIQ loses an unusually large chunk of range while still under 8 years/100,000 miles, it’s worth having a Cadillac EV‑certified dealer document and diagnose it**. That diagnostic record is what underpins any potential warranty claim.
What’s covered vs. not covered on a LYRIQ battery
Commonly covered battery issues
- Defects in materials or workmanship inside the high‑voltage battery pack or its internal modules.
- Internal component failures that cause the pack to shut down, inhibit charging, or trigger persistent high‑voltage error codes.
- Abnormal capacity loss beyond Cadillac’s stated threshold during the warranty period (verified with diagnostics).
- Pack sealing or coolant‑related issues that arise from manufacturing defects, not outside damage.
Typical exclusions and gray areas
- Collision or impact damage to the battery, even if the vehicle is still drivable (this is an insurance claim, not a warranty item).
- Damage from improper charging, including use of unapproved equipment or ignoring warnings in the owner’s manual.
- Unauthorized modifications to the battery pack, cooling system, or high‑voltage wiring.
- Normal degradation that stays within Cadillac’s stated capacity‑retention limits for age and mileage.
- Neglect of required maintenance, especially cooling‑system service intervals if specified in the maintenance schedule.
Don’t gamble with DIY high‑voltage work
Beyond the battery itself, the EV propulsion warranty typically extends to **high‑voltage cables and drive electronics directly tied to moving energy to and from the pack**. Components like onboard chargers, DC fast‑charge hardware, and certain power electronics may fall under this umbrella, again, the warranty booklet for your VIN is the authoritative source.
Warranty rules for second owners and used LYRIQs
Cadillac designs the LYRIQ battery warranty to **follow the vehicle, not just the first owner**. That’s crucial if you’re shopping used or planning to sell before 8 years/100,000 miles:

Good news for used shoppers
If you’re buying privately or from a non‑Cadillac dealer, it’s worth having a Cadillac EV‑certified dealer **run the VIN and confirm remaining warranty**. At Recharged, we simplify that process by verifying warranty status as part of our intake and inspection on every LYRIQ we list.
Real‑world battery life vs. Cadillac’s warranty limits
The **8‑year/100,000‑mile** warranty is designed to outlast what most first and even second owners will put on a LYRIQ. Industry‑wide data in 2025 and 2026 shows that modern EV packs, especially those using advanced chemistries like GM’s nickel‑manganese‑cobalt‑aluminum (NCMA) Ultium cells, generally retain **70–80% of original capacity even beyond 8 years** when treated reasonably well.
In other words, Cadillac’s warranty limits are **conservative benchmarks**, not expected failure points. Under normal use, you should expect:
- A **gradual, modest decline in range** over the first 5–8 years, often barely noticeable year‑to‑year.
- Better retention if you **avoid frequent 100% DC fast charges** and keep the car plugged‑in and conditioned in hot or cold climates.
- The odds of full battery replacement under warranty to be **quite low**, given the pack’s built‑in thermal management and robust design.
Thermal management is your friend
Still, real‑world use is messy: some owners fast‑charge constantly, live in very hot climates, or tow trailers. That’s why **monitoring actual battery health matters**, especially as the car ages and approaches the end of factory coverage.
How to protect your LYRIQ battery, and keep coverage intact
Six habits that keep your LYRIQ battery, and its warranty, in good shape
1. Stay within Cadillac’s charging guidelines
Use **approved Level 2 and DC fast chargers** and follow the charging recommendations in your LYRIQ owner’s manual. Ignoring warnings or using improvised adapters can put both your battery and warranty at risk.
2. Keep daily charging around 80%
For everyday commuting, set your charge limit around **80% state of charge**, then raise it before road trips. This reduces stress on the pack and aligns with Cadillac’s own guidance for promoting long‑term battery health.
3. Avoid constant 0–100% swings
Try not to run the battery down to near‑zero or leave it at 100% for days at a time. Shallower cycles, say, 20–80%, are easier on the battery and still deliver plenty of usable range.
4. Let the car manage temperature
In extreme heat or cold, **keep your LYRIQ plugged in** so the thermal‑management system can precondition the pack. This helps both range and longevity, and it’s how Cadillac designed the car to be used.
5. Keep software and maintenance up to date
Apply **software updates** and follow any recommended cooling‑system service intervals. Skipping required maintenance related to the battery or thermal system can compromise warranty coverage.
6. Document issues early
If you see unusual range loss, charging errors, or persistent warnings, **get them documented at a Cadillac EV‑certified dealer** while you’re still under warranty. Early documentation makes later claims much easier.
Consider extended protection on chargers, too
