Key reliability signals for the Mercedes EQS
Data note
How reliable is the 2024 Mercedes EQS versus earlier years?
To understand **2024 Mercedes EQS reliability**, you have to start with the early years. The EQS launched for 2022 as Mercedes’ first dedicated luxury EV flagship. That first model year combined an all‑new platform, huge Hyperscreen interior, and a dense stack of driver‑assist tech, exactly the recipe that tends to create early‑run bugs.
2022–2023 EQS: promising but glitchy
- Software glitches causing random warnings, frozen cameras, and Apple CarPlay dropouts.
- Isolated cases of sensor failures that disabled lane‑keeping or emergency braking until the car was restarted.
- Occasional build issues: squeaky sunroof rails, creaking seats, delicate windshields, and sticky door handles.
- Overall J.D. Power quality & reliability scores in the mid‑70s to high‑70s, not terrible, but not class‑leading.
2024 EQS: incremental refinement
- Most serious bugs addressed through **software updates** and running production changes by the time 2024s reach customers.
- Owner reports from 2023–2024 build cars increasingly describe **“annoyances, not deal‑breakers”**, especially while under warranty.
- No pattern of high‑voltage battery failures or widespread drivetrain issues in normal use.
- Predicted reliability for 2024 is best described as **“average for a tech‑heavy luxury EV”** rather than a standout worry, or standout hero.
Lease vs. buy perspective
Common 2024 EQS problems and owner complaints
Because the 2024 EQS shares its core hardware with 2022–2023 models, the **pattern of complaints looks similar**. Most issues are in the "computers and comfort" category, not the battery or motors. Here’s what tends to show up in owner forums and service visits.
Most common EQS trouble spots
What you’re more likely to deal with on a 2024 EQS
Infotainment & connectivity
- Apple CarPlay/Android Auto randomly disconnecting.
- Slow boot‑up or laggy responses from the Hyperscreen.
- Occasional black‑screen events that require a restart.
Frequently resolved with over‑the‑air or dealer software updates.
Driver‑assist & sensors
- Random collision warnings or beeps with no obstacles.
- Lane‑assist or adaptive cruise briefly disabled due to sensor errors.
- 360° camera glitches, especially in poor weather.
Usually not dangerous but can undermine confidence if it happens often.
Interior noises & trim
- Creaking from the driver’s seat or center console.
- Wind noise around the sunroof on some early builds.
- Broken third‑row levers or minor hardware in SUVs.
Annoying, but typically addressed under warranty when documented early.
Red‑flag reliability pattern: repeat visits
Battery, range, and charging reliability
For a used EV buyer, **battery health is the whole ballgame**. The good news is that the EQS’s large pack and conservative thermal management have not produced a wave of high‑profile failures. Range loss over the first few years appears modest when cars are charged and driven normally.
- EQS sedan and SUV both use a large battery (around 108 kWh usable in early years), which helps reduce daily depth‑of‑discharge stress.
- Most real‑world owner stories focus on **software and interior issues**, not pack replacements or sudden range collapse.
- Mercedes provides an **8‑year / 100,000‑mile high‑voltage battery warranty** in the U.S., which still covers a 2024 EQS well into the 2030s for first owners and many used buyers.
Check battery health before you sign
Charging behavior: what EQS owners report
Not deal‑breaking, but worth knowing before you road‑trip
DC fast charging
- Peak DC speeds are competitive but not class‑leading due to a 400‑volt architecture.
- Charge curves are generally predictable; major failures are rare.
- Some owners note that software updates can slightly change charging behavior over time.
AC home charging
- Onboard charger is robust; wall‑box issues are usually **installer or hardware**, not the EQS.
- Occasional bugs with scheduled charging or preconditioning that require a reboot or software update.
- Best experience comes from a well‑installed Level 2 charger and reliable Wi‑Fi for OTA updates.
Does the EQS SUV differ from the sedan on reliability?
By 2024, the **EQS sedan and EQS SUV share most of their electric hardware and software**, but there are a few meaningful differences for reliability and day‑to‑day livability.
EQS sedan (450+ / 580)
- Lower, more aero‑efficient body tends to deliver the best real‑world range.
- Most early reliability data comes from sedans, so patterns are better understood.
- Reported issues focus on **electronics and interior trim**, not structure.
- Slightly simpler packaging than the three‑row SUV.
EQS SUV (450+ / 580 / AMG)
- Added complexity from the **third row, air suspension, and interior hardware**.
- Some owners mention weaker A/C airflow to the third row and small interior rattles.
- As of early 2026, the **2024 EQS SUV shows no active NHTSA recalls**, which is a positive sign.
- If you frequently use all three rows, budget for slightly higher wear on interior components.
Choosing between them
Warranty, recalls, and software updates
The 2024 EQS lives and dies by its software. That’s a liability when things go wrong, but also a strength, because Mercedes can fix a surprising amount without replacing hardware. Understanding **what’s covered and how updates work** is critical before you buy used.
2024 Mercedes EQS U.S. warranty coverage (typical)
Always confirm specifics by VIN and in writing, this table is a general guide, not a contract.
| Coverage type | Typical term | What it covers | Why it matters on a used EQS |
|---|---|---|---|
| Basic (bumper‑to‑bumper) | 4 years / 50,000 miles | Most electronics, interior hardware, infotainment, cameras, driver‑assist systems. | Most EQS issues live here. Aim to buy with at least 1–2 years of basic warranty remaining. |
| Powertrain | Same as basic | Electric motors, reduction gear, related components. | True powertrain failures are rare, but coverage adds peace of mind. |
| High‑voltage battery | 8 years / 100,000 miles | Defects in the battery pack and severe capacity loss (under Mercedes criteria). | Critical for long‑term ownership. A 2024 EQS should be covered well into the 2030s. |
| Corrosion & emissions | Varies by state and component | Rust‑through and emissions‑related items. | Less central for EVs but still relevant in harsh climates. |
Warranty can shift with in‑service date and ownership changes; verify with a Mercedes dealer before purchase.
Make updates your friend, not your enemy
On the recall front, the EQS line has seen a handful of **software and component‑specific recalls** in its early years, but nothing like a systemic battery‑fire crisis. As of early 2026, databases show **no active recalls for the 2024 EQS SUV**, and only a small number of software‑driven campaigns for the broader EQ range. Still, you should always run the VIN through the NHTSA site or a dealer before you buy.
Reliability, depreciation, and cost of ownership
Reliability is only half the story. The EQS has also become one of the **most heavily discounted luxury EVs** on the used market, thanks to aggressive new‑car incentives, a soft EV market in 2025, and Mercedes’ own pricing resets.
How reliability and value intersect on the EQS
Why the EQS looks risky on paper, but intriguing in your driveway
Big depreciation = opportunity
Three‑year‑old EQS sedans have been seen at **30–40% of original MSRP**, especially former leases. That hurts the first owner, but makes **lightly used 2024s surprisingly attainable**.
Repair costs are premium
When something does break out of warranty, especially electronics or trim, you’re paying **S‑Class money for parts and labor**. That’s why staying within warranty or buying with coverage matters.
Lower running costs than gas S‑Class
Electric drivetrains mean no oil changes, fewer moving parts, and lower fuel spend. If your EQS behaves, **total cost of ownership can undercut a comparable gas Mercedes**, even with higher repair rates.
Who should avoid the EQS
Should you buy a used 2024 EQS? Who it fits best
Put all of this together and **2024 Mercedes EQS reliability** lands in the middle of the pack: not a nightmare, not a Toyota. The car you pick matters as much as the model year. Some EQS owners report thousands of trouble‑free miles; others have one bad VIN that lives at the service bay.
Great fit if this is you
- You want **top‑tier comfort and tech** more than minimalist simplicity.
- You’re comfortable with dealer visits for the occasional software or hardware fix.
- You can keep the car under **factory or extended warranty** during your ownership.
- You value a **quiet, long‑range cruiser** over track‑worthy performance.
Think twice if this is you
- You live far from a Mercedes dealer or don’t have time for repeat visits.
- You want **“set it and forget it” reliability** above all else.
- You plan to run the car long after warranty ends with minimal savings for repairs.
- You’re sensitive to dashboard warnings or intermittent tech quirks.

6. Listen for squeaks and rattles
Drive on rough pavement at low speed with the radio off. Pay attention to **seat creaks, sunroof noises, and third‑row hardware** in the SUV.
7. Inspect tires and suspension
The EQS is heavy. Uneven tire wear or clunks over bumps can point to **suspension alignment or bushing issues** that will cost real money to fix.
8. Check climate control in all rows
On the EQS SUV, run the A/C and heat with passengers in every row. Confirm **adequate airflow and temperature control**, especially in the third row.
9. Verify charging behavior
If possible, plug into both Level 2 and a DC fast charger. Watch for **error messages, unusually low charge rates, or repeated session drops**.
10. Lock in warranty coverage
Know exactly how much **factory warranty** remains. If you’re close to the cutoff, price in an extended warranty or negotiate accordingly.
FAQ: 2024 Mercedes EQS reliability
Frequently asked questions about 2024 EQS reliability
Bottom line: Is the 2024 EQS a smart used buy?
If you’re shopping strictly by reliability charts, the 2024 Mercedes EQS won’t look like a Camry. But that’s not the point.
