If you’re driving, or thinking about buying, a Cadillac Lyriq, the big, unspoken question is usually the same: what happens if the battery goes bad, and how much will it cost to replace? With the Lyriq’s Ultium pack making up a huge share of the SUV’s value, understanding realistic Cadillac Lyriq battery replacement cost and warranty coverage is key to making a smart ownership or used‑purchase decision.
First things first
As of early 2026, almost all Lyriq high‑voltage battery replacements in the U.S. have been handled under warranty. That’s good news, but it also means hard out‑of‑pocket price data is limited, so any cash estimates are informed, not exact quotes.
Cadillac Lyriq battery replacement cost in 2026: the short answer
No Cadillac dealer is going to give you a single, universal number for Lyriq battery replacement. But based on current EV pack pricing for similar 90–100 kWh luxury SUVs, GM Ultium component pricing, and real‑world EV battery jobs reported in 2024–2025, a realistic 2026 planning range for a full out‑of‑warranty Lyriq pack replacement in the U.S. looks like this:
Estimated Cadillac Lyriq battery replacement cost (out of warranty)
Approximate 2026 U.S. pricing for a full high‑voltage battery pack replacement on a Cadillac Lyriq, including parts and labor. These are planning numbers, not quotes.
| Scenario | What it includes | Estimated parts cost | Estimated labor & programming | Estimated total |
|---|---|---|---|---|
| New OEM Ultium pack at Cadillac dealer | Brand‑new GM Ultium pack, dealer labor, programming, coolant service | $18,000–$24,000 | $2,500–$4,000 | $20,500–$28,000 |
| GM remanufactured/secondary pack | Factory‑reman pack or service unit, dealer install | $13,000–$18,000 | $2,500–$4,000 | $15,500–$22,000 |
| Used/salvage Ultium pack at independent EV shop | Low‑mileage salvage Lyriq/Ultium pack with shop warranty | $9,000–$14,000 | $2,000–$3,500 | $11,000–$17,500 |
| Module‑level repair only | Replace a failed module, contactor, or coolant component; pack stays in vehicle or is re‑used | $1,000–$4,000 | $1,000–$2,500 | $2,000–$6,500 |
Use this as a budgeting tool, always get written quotes from Cadillac dealers or EV‑specialist shops before committing.
Treat these numbers as worst‑case
These estimates assume you are out of warranty and need a major repair or full pack. Many owners will never face anything close to these costs, especially within the first 8–10 years when GM’s EV battery warranty is still active.
Why Lyriq battery replacement cost is still hard to pin down
The Lyriq only launched for the 2023 model year, which means the fleet is still young and firmly inside its high‑voltage battery warranty window. When failures do happen today, GM is typically authorizing replacements under warranty, so owners never see an itemized bill. That’s great for current drivers, but it makes out‑of‑pocket cost data scarce.
- Lyriqs are built on GM’s Ultium architecture, which uses large pouch cells and a structural pack unique to this generation of EVs.
- Most failures so far show up as “Service High Voltage Battery” or similar warnings within the first few years and are being addressed by dealers with GM engineering support, not billed as customer‑pay jobs.
- Battery cell pricing for large packs (90–100 kWh) is still falling, and GM has publicly targeted substantial per‑kWh cost reductions across its Ultium lineup over the next few years.
- A significant share of early Lyriq battery‑system issues appear to be module, sensor, or coolant‑system related rather than across‑the‑board cell degradation. Those can often be repaired without replacing the entire pack.
Think like an actuary, not a gambler
With any modern EV, especially a new platform, the right question isn’t “What’s the exact battery replacement price?” It’s “What’s the realistic probability I’ll ever face that bill, and how do warranty coverage and resale value balance that risk?”
Lyriq battery warranty: what GM actually covers
The Cadillac Lyriq’s high‑voltage battery is covered by GM’s EV battery limited warranty, which, depending on model year and state, typically runs around 8 years or 100,000 miles (sometimes longer in CARB states). You’ll want to confirm the exact terms in your owner’s manual or with a Cadillac dealer, but the broad strokes are consistent with other GM EVs.
- Defects in materials or workmanship for the high‑voltage battery and related components during the warranty term.
- Coverage for many “Service High Voltage Battery” faults, if GM determines a component inside the battery system has failed.
- In many markets, coverage against excessive capacity loss (for example, if the battery falls below a specified percentage of original capacity within the warranty period).
- Associated labor, diagnostics, coolant, and programming when the fix is covered under warranty.
Real‑world Lyriq warranty experience
Owner reports so far suggest that when a Lyriq throws a genuine high‑voltage battery fault in the first few years, GM is authorizing full pack replacements or major repairs at no cost to the owner, often including a loaner vehicle, even if parts availability can take weeks.
Beyond the factory warranty, Cadillac also markets an EV Protection Plan that can extend coverage on thousands of components, plus separate PowerUp coverage for home chargers. These plans don’t change the basic high‑voltage battery warranty, but they can reduce surprises elsewhere in the ownership experience.
Full battery replacement vs. repair: what usually happens
When you see the phrase “battery replacement,” it’s easy to imagine a total pack swap every time something goes wrong. In practice, full pack replacements are the exception, even on early‑life Lyriqs. Dealers and GM engineers try to narrow issues down to specific components first.
How Lyriq battery problems are typically handled
Understanding the difference between major repair and true replacement
Battery-system repair
Most common outcome for issues caught under warranty.
- Diagnose fault codes and test the pack.
- Replace failed modules, contactors, sensors, or coolant heaters.
- Re‑seal and re‑commission the pack.
- Vehicle is returned with the original pack, but restored function.
This is usually much cheaper than a full pack swap once out of warranty.
Full pack replacement
Less common, but it happens, especially with early-build vehicles that show repeated high‑voltage faults.
- GM ships a new or remanufactured Ultium pack.
- Dealer drops the old pack and installs the replacement.
- Software, coolant circuits, and safety checks are updated.
- Old pack may be remanufactured or recycled.
Out of warranty, this is the scenario where $15k–$25k bills become possible.
Ask the right question at the dealer
If your Lyriq throws a high‑voltage fault, don’t just ask, “Is it the battery?” Ask, “Are we talking about a component repair or a full pack replacement?” That distinction matters far more for long‑term cost and resale value.
Cadillac Lyriq battery replacement cost breakdown (2026 estimates)
If you strip the emotion out of it, a Lyriq pack is a sophisticated but fairly predictable bill of materials: cells, pack hardware, cooling system, and labor. Here’s how those estimated totals from earlier likely break down in 2026 dollars.

6 factors that drive your final Lyriq battery bill
Key variables that change your Lyriq battery cost
1. In‑warranty vs. out‑of‑warranty
If your Lyriq is still inside its high‑voltage battery warranty and GM confirms a covered failure, your out‑of‑pocket cost is typically $0, aside from time and inconvenience. Once that warranty expires, you own 100% of the risk.
2. Full pack vs. partial repair
A coolant heater, contactor, or isolated module can often be replaced for a small fraction of a full pack’s cost. Make sure diagnostics are thorough before anyone starts talking about a complete Ultium replacement.
3. New GM pack vs. used/reman
A brand‑new Ultium pack sourced through a Cadillac dealer will almost always be the most expensive option. A used or reman pack from a donor Lyriq can knock thousands off the parts cost, at the expense of some warranty length and peace of mind.
4. Labor rate and shop type
Dealer labor rates in dense urban areas can be double what an independent EV‑focused shop in a smaller market charges. On a 20‑hour job, that alone can swing the bill by several thousand dollars.
5. Software and accessory work
Pack replacement often requires software updates, coolant refills, and high‑voltage safety inspections. These are usually bundled into the job, but they’re part of why EV battery work isn’t just “parts + two hours of labor.”
6. Future cell pricing
Battery costs are still trending down as GM and LG scale new chemistries and manufacturing. A Lyriq pack replaced in 2030 may be meaningfully cheaper than one replaced in 2026, though labor and shop rates may rise.
Common Lyriq high-voltage battery issues and warning signs
Early Lyriq owners have already shared a pattern of high‑voltage issues online. The good news: most of these have been handled under warranty. The bad news: they can still sideline the car for days or weeks while parts arrive and GM engineering analyzes logs.
- “Service High Voltage Battery” warnings appearing during driving or charging, sometimes accompanied by reduced performance or disabled HVAC.
- Charging sessions that suddenly drop to very low power levels at DC fast chargers (e.g., stuck around 5 kW) even with a warm battery and healthy charger.
- The car refusing to accept a charge at all, often right after a high‑voltage alert or while plugged in at home.
- Repeated faults after a prior repair, suggesting deeper issues in the pack or high‑voltage electronics.
Safety first
If your Lyriq shows a high‑voltage battery or system alert and tells you to stop driving, take it seriously. Use OnStar or roadside assistance, get it towed to a Cadillac dealer, and let them diagnose it. High‑voltage systems are not DIY territory.
Buying a used Lyriq? Battery‑risk checklist
If you’re shopping for a used Lyriq, you’re not just buying a luxury SUV, you’re buying a specific high‑voltage pack with a specific history. The trick is turning that from an unknown into something you can actually evaluate.
Used Lyriq battery due diligence
1. Confirm remaining battery warranty
Ask the seller for the in‑service date, current mileage, and whether the car was originally sold in a CARB state. This tells you exactly how much high‑voltage battery warranty is left, or if it’s already expired.
2. Pull service and recall history
Look for any prior <strong>high‑voltage battery</strong> or charging‑system repairs. A properly resolved early‑life issue isn’t necessarily a red flag, but repeated visits for the same codes might be.
3. Get a third‑party battery health report
Capacity loss isn’t always obvious from the dashboard. A proper battery health test can estimate usable kWh and degradation, which is crucial if you’re buying a high‑mileage Lyriq or planning to keep it long‑term.
4. Test both AC and DC charging
Before you sign anything, plug into a Level 2 charger and a DC fast charger if possible. Watch for normal charge rates, stable behavior, and the absence of warning messages.
5. Drive a full cycle if you can
A longer test drive that includes highway speeds, hills, and HVAC use can reveal range inconsistencies or thermal‑management issues you won’t see on a quick spin around the block.
6. Price in worst‑case risk
For older, higher‑mileage Lyriqs that are out of battery warranty, make sure the asking price reflects the small but real possibility of a big battery bill down the road.
How Recharged helps you manage Lyriq battery risk
Big‑ticket components like the Lyriq’s Ultium pack are exactly why Recharged exists. When you buy a used EV through Recharged, you’re not guessing about battery health, you can actually see it.
Recharged Score battery diagnostics
Every vehicle on Recharged comes with a Recharged Score Report that includes verified battery health, range performance, and pricing aligned with that data. Instead of hoping the Lyriq you’re looking at has a healthy pack, you can see how its battery compares to similar vehicles.
If a car shows unusual degradation or a history of high‑voltage issues, that’s reflected in both the Score and the price, or the car doesn’t make the cut at all.
Transparent pricing, financing, and protection
Because the battery is such a large share of a Lyriq’s value, Recharged bakes battery condition into fair‑market pricing and financing options. You can also explore protection plans and nationwide delivery through a fully digital, EV‑specialist experience, or visit the Recharged Experience Center in Richmond, VA if you want to see vehicles in person.
Use battery health as a negotiation tool
When you can point to a third‑party battery health report, you’re not just haggling, you’re pricing a used Lyriq the way a lender or actuary would. That’s a big advantage over eyeballing range on a test drive.
