How the 2024 Mercedes EQS is rated for reliability
Formal reliability data always lags new model years. As of early 2026, large third‑party studies still focus on 2022–2023 EQS models, which share platforms and most components with the 2024 car. Those ratings are the best guide we have so far.
- JD Power Quality & Reliability: The EQS earns a mid‑70s score out of 100, which is solid but not class‑leading among modern Mercedes models. It’s the lowest‑scoring Mercedes in that list, but still considered "average to better than average" overall.
- Kelley Blue Book owner reviews: 2024 EQS owners give it about 4.4 out of 5 stars, with 80% awarding a perfect 5, and roughly 88% saying they’d recommend the vehicle.
- Owner sentiment split: Many drivers report zero issues over the first 10,000–30,000 miles, while a smaller but vocal group describes sensor, ADAS, or software gremlins that require repeated dealer visits.
How to read these numbers
Common 2024 EQS problems owners report
So what actually goes wrong on the EQS in the real world? Looking across owner forums, early service records and anecdotal reports, a few patterns show up on 2022–2024 EQS sedans and SUVs. Not every car sees these issues, but they’re worth watching for, especially if you’re buying used.
Typical EQS trouble spots (2022–2024)
Most are software or comfort‑related, not battery defects
Software & infotainment glitches
- Apple CarPlay / Android Auto disconnects intermittently.
- Laggy user interface or frozen screens.
- Random error messages that resolve with an update or reboot.
These are usually fixed via over‑the‑air or dealer software updates.
Sensors, cameras & ADAS quirks
- 360° camera or parking sensors temporarily unavailable.
- Lane‑keep assist behaving aggressively during lane changes.
- Occasional ADAS system warnings or temporary shutdowns.
Most are nuisance faults, but any unexpected steering or braking behavior should be logged and addressed immediately.
Comfort & body hardware
- Seat creaks or interior noises in high‑mileage cars.
- Wind noise from panoramic roof area on some sedans.
- Door handle or tailgate sensor issues in isolated cases.
These are typical luxury‑car aging issues, but still worth checking on a test drive.
Take ADAS complaints seriously
On the positive side, there is no widespread pattern of drivetrain or battery pack failures on the EQS. The most consistent reliability complaints center on the car’s digital brain, software, sensors and driver‑assist systems, rather than its motors or pack.
Battery health and long‑term durability
For any used electric luxury sedan, the biggest long‑term question is battery health. A replacement high‑voltage pack can cost five figures, so you want to know how the EQS chemistry is aging.
What we’re seeing so far
- No systemic 2024 EQS battery recall or defect has emerged to date.
- Owners with 20,000–40,000 miles generally report modest range loss, typical of premium EVs in this segment.
- The EQS uses a large pack, so even 5–10% degradation still leaves generous real‑world range.
Why battery checks still matter
- Individual cars can be abused, frequent DC fast charging, hot climates, or sitting at 100% charge.
- Software may mask some degradation behind optimistic range estimates.
- A precise state‑of‑health (SoH) reading is the only way to know how healthy the pack really is.

Browse VehiclesWhere the EQS fits in Mercedes EQ reliability
Mercedes’ EQ lineup now spans compact crossovers to full‑size luxury sedans and SUVs. The EQS sits at the very top of that family, both in price and complexity, and that shows up in reliability patterns.
How the EQS compares within the EQ lineup
High‑level view of reliability expectations across Mercedes EQ models in the U.S. market.
| Model | Segment | Typical Use Case | Reliability Pattern |
|---|---|---|---|
| EQA / EQB | Compact crossover | Family runabout, short trips | Simpler hardware; main concerns are minor electronics and a recent EQB battery‑cell recall, not constant roadside failures. |
| EQE sedan/SUV | Midsize luxury | Daily commuter, family hauler | Shares much of the EQS tech; reports mirror EQS with occasional software and sensor quirks. |
| EQS sedan/SUV | Flagship luxury | Long‑distance cruiser, executive car | Most comfortable and advanced, but also the most complex. Reliability is generally good, with an above‑average number of software/ADAS niggles. |
Flagship hardware and software make the EQS more complex than its smaller EQ siblings, great for comfort, but something to remember when thinking about long‑term ownership.
EQS vs S‑Class
Maintenance costs, warranty coverage and recalls
Reliability isn’t just about what breaks; it’s also about what it costs to fix and how long the factory stands behind the car. On that front, the 2024 EQS is a mixed bag: generous battery coverage, predictable service needs, but expensive out‑of‑warranty repairs if something complex fails.
What protects you on a 2024 EQS
Factory coverage plus what to expect after it ends
Basic warranty
Most 2024 EQS models are covered by a 4‑year / 50,000‑mile new‑vehicle warranty from original in‑service date. That covers most electronics, ADAS, interior and body hardware.
High‑voltage battery
Like most EVs, the EQS battery is typically covered for around 8 years / 100,000+ miles against major defects, giving added peace of mind to the second owner.
Maintenance & wear items
EVs skip oil changes, but the EQS still needs brake fluid, cabin filters, tires and alignment. The car’s weight and power mean tires and suspension components aren’t cheap.
Luxury EV = luxury repair bills
On the recall front, the EQS has seen far fewer headline‑grabbing issues than some rivals, and recent high‑profile battery recalls in the Mercedes lineup have focused on other models (such as certain EQB SUVs). Still, you should always run a VIN check for open recalls and verify that all software campaigns and safety updates have been completed.
Should you buy a used 2024 Mercedes EQS?
A lightly used 2024 EQS can be a compelling value play. Prices have cooled from early‑launch highs, and you’re getting flagship comfort, range and tech at a substantial discount, often while some factory warranty remains. The trade‑off is accepting a car with more software and electronics than most luxury sedans, and being realistic about long‑term costs.
Why a used 2024 EQS makes sense
- Early depreciation means lower upfront cost for a still‑current design.
- Refined, quiet ride and high build quality for long trips.
- Battery reliability looks solid so far, with no systemic 2024 pack issues.
- Plenty of range and fast‑charging capability for road‑trip use.
What to watch out for
- Cars with repeated ADAS or sensor faults in their history, these can be chronic.
- Out‑of‑warranty examples with spotty service records.
- Minor tech glitches that don’t show on a quick test drive but frustrate day‑to‑day.
- High‑mileage cars used heavily for DC fast charging without battery documentation.
How Recharged can help you shop
Pre‑purchase checklist for a used EQS
Before you commit to a 2024 EQS, whether through a private seller, a franchise store, or an online marketplace, walk through a structured checklist. With a tech‑heavy car like this, the details matter.
Used 2024 EQS buyer checklist
1. Verify remaining factory warranty
Confirm the original in‑service date and mileage. Ideally, your EQS still has <strong>at least a year or two</strong> of new‑car or CPO coverage for electronic and ADAS issues.
2. Get a real battery health report
Don’t rely on the dash range number alone. Ask for a <strong>formal battery state‑of‑health test</strong> or buy from a retailer like Recharged that includes a detailed battery report in every purchase.
3. Scan for open recalls and software updates
Run the VIN through Mercedes’ recall lookup and ask for a <strong>dealer printout of completed campaigns</strong>. Make sure major software updates and safety fixes are installed.
4. Test every ADAS and parking feature
On the test drive, deliberately try adaptive cruise, lane‑keep assist, automated parking, 360° cameras and blind‑spot warnings. Watch for <strong>false alerts, aggressive steering inputs</strong> or features that shut down unexpectedly.
5. Listen for noises and inspect interior tech
Check for creaks from seats or the panoramic roof, dead pixels on the Hyperscreen, laggy response, or audio glitches. These issues aren’t always deal‑breakers, but they’re negotiation points.
6. Review complete service history
Look for <strong>repeat visits for the same complaint</strong>, especially ADAS, steering or sensor issues. A one‑time fix is normal; a pattern can signal a problem car.
7. Consider total cost of ownership
Price out typical EQS items, tires, brakes, suspension, extended warranty. Even with low energy costs, a flagship Mercedes will never be cheap to maintain out of warranty.
