If you’re looking at a used 2023 Audi Q4 e-tron, you’ve probably heard mixed things about reliability. Some owners love theirs; others talk about warning lights, recalls, or software gremlins. In this guide, we’ll unpack the real-world 2023 Audi Q4 e-tron problems, how serious they are, and what to look for if you’re thinking about buying one used.
Quick take
Overview: How Serious Are 2023 Audi Q4 e-tron Problems?
The 2023 Q4 e-tron shares its platform with the Volkswagen ID.4, and like that cousin, it’s had its share of software bugs, warning lights, and recall campaigns. Independent data shows that the 2023 Q4 e-tron has been recalled multiple times and is rated "less reliable than the average new car" for its model year. That doesn’t mean every Q4 is a headache, but it does mean you should go in with your eyes open, especially in the used market.

Common 2023 Audi Q4 e-tron Problems Owners Report
Official recalls only tell part of the story. Owner forums, service bulletins, and shop data paint a fuller picture of the 2023 Q4 e-tron’s pattern of issues. Here are the problem areas we see mentioned most often.
Top Problem Areas on the 2023 Q4 e-tron
Most issues are fixable, if you know to look for them.
Software & warning lights
A/C and climate quirks
Charging/control electronics
1. Software bugs and digital “gremlins”
If there’s a single theme with the Q4 e-tron, it’s that the software sometimes feels a generation behind the hardware. Owners describe cascades of warning messages at startup, phantom alerts for stability control or driver-assist features, and infotainment freezes. In many cases, the vehicle will still drive normally, but it undermines confidence, especially for new EV owners.
Why this happens
- Repeated warning messages at startup that clear after cycling the power
- Laggy or frozen infotainment screen; slow response to touch or voice commands
- Driver-assistance features temporarily unavailable until the next drive cycle
- App connectivity hiccups, vehicle not updating status or failing to accept remote commands
2. HVAC and A/C issues
A recurring complaint involves the air-conditioning system. Some 2023 Q4 e-tron owners report random “A/C malfunction” messages or days when the A/C simply won’t blow cold, then works fine the next day. In a number of cases, dealer diagnosis turns up a refrigerant leak or a failing component in the A/C circuit; in others, the fix is a software update or control-module reset.
Why A/C problems matter on an EV
3. Charging and electrical quirks
The 2023 Q4 e-tron generally charges as advertised, but some owners have reported sessions that won’t initiate on first plug‑in, or fast‑charge sessions that slow dramatically before the battery is actually full. Others note that wallbox chargers occasionally fail to wake the car, requiring them to unplug and try again.
- DC fast-charging speed that drops earlier than expected in the charge curve
- Occasional failure to initiate charging, most often resolved by unplugging and reconnecting
- On-board charger errors after power outages or flaky home wiring
- Public chargers that work fine with other EVs but are finicky with the Q4’s software timing
4. Interior noises, trim, and minor hardware
Because the Q4 e-tron is quiet at speed, relatively small issues like trim creaks, rattles, or wind noise are easier to notice. A number of owners mention minor buzzes in the dash, door seals that need adjustment, or squeaks from the rear cargo area. Individually they’re not catastrophic, but they add up if the car hasn’t been carefully prepped.
The good news
Battery, Range, and Charging: Real-World Behavior
The core EV hardware in the 2023 Q4 e-tron, battery pack, motors, and power electronics, has not been the main source of complaints. Instead, owners are usually reacting to real‑world range and charge-curve behavior that doesn’t always match the brochure numbers, especially in cold weather or at high speeds.

Battery degradation so far
Because the Q4 e-tron launched recently, there isn’t yet a long track record of high‑mileage battery degradation. Early reports from 2021–2023 builds suggest modest capacity loss over the first few years when the car is charged sensibly, avoiding frequent 100% fast‑charges and heavy abuse at very low charge levels.
Battery warranty basics
Repair Costs, Warranty Coverage, and Who Pays
When we talk about “problems,” what most buyers really want to know is: who pays when something breaks? The answer on a 2023 Q4 e-tron depends heavily on mileage, original in‑service date, and whether prior owners kept up with service and recalls.
Typical out-of-pocket repair ranges
- Software & module glitches: Often covered under warranty; out of warranty, diagnostic + programming can run a few hundred dollars.
- HVAC issues: Simple sensor or valve work may be modest; chasing leaks, replacing components, and recharging the system can climb quickly.
- Charging hardware faults: Wallbox problems are usually on the home‑charger side; on‑board charger or DC fast‑charge hardware is far more expensive but often warranty‑covered on a 2023.
- Trim and noise fixes: Usually labor‑heavy but parts‑light, more about time than big-ticket components.
What the factory warranty typically covers
- Bumper‑to‑bumper coverage on a 2023 Q4 e‑tron should still apply for many U.S. cars today, depending on in‑service date and miles.
- High-voltage battery and drive components are usually covered for a longer period than regular components.
- Recall work is always free, regardless of age or mileage.
- Owner damage, lack of maintenance, and some wear items fall outside warranty; a good service history is your best protection.
Don’t rely on “it’s still under warranty” alone
Used 2023 Q4 e-tron Buyer’s Problem Checklist
If you’re shopping used, you don’t need to be an engineer. You just need a repeatable process. Here’s a practical checklist focused specifically on 2023 Audi Q4 e-tron problems and how to spot them before you sign anything.
Pre‑Purchase Checklist for a Used 2023 Audi Q4 e-tron
1. Run the VIN for recalls and software campaigns
Confirm that all major recalls, especially the <strong>gear-indicator/rollaway</strong>, headlight software, and airbag/door-seal campaigns, have been completed. Ask for printed service records showing these repairs.
2. Scan for warning lights and error messages
On a cold start, look for any persistent warnings in the digital cluster. Cycle the car off and back on at least once. A healthy Q4 e‑tron should boot cleanly without a parade of alerts.
3. Stress‑test the infotainment and app
Spend time with the center screen: navigation, audio, drive‑mode settings, and climate controls. Make sure the system is responsive, doesn’t freeze, and that the companion app can connect and update vehicle status.
4. Test A/C and heat thoroughly
Run the climate system in both cooling and heating modes. Change fan speeds, temps, and zones. You’re looking for <strong>consistent temperature control</strong>, no odd smells, and no “A/C malfunction” messages.
5. Check home and public charging behavior
If possible, plug into a Level 2 charger and a DC fast charger. Confirm that charging starts quickly, maintains expected power levels, and stops cleanly without error messages or repeated plug‑in attempts.
6. Listen for rattles and wind noise
On a smooth road at 45–65 mph, turn the audio off and listen. Pay attention to door seals, the dash, and the cargo area. Minor noises can be fixed, but a car that buzzes like a drum set may never feel truly premium.
