Audi Q4 e-tron Lemon Law Lawyer in San Diego

An Audi Q4 e-tron lemon law lawyer first separates ordinary battery aging from a defect the battery warranty has to fix.

Run your VIN through NHTSA's recall search first. Under California's Song-Beverly Act, Audi owes a buyback, refunding the price, or a replacement, meaning a substantially identical new vehicle. That duty arises when Audi cannot fix a qualifying defect within a reasonable number of repair attempts, meaning a fair number of chances.

Cline APC takes only lemon law and warranty cases, from La Jolla and Poway. If your Q4 keeps losing range or refusing to charge, call (888) 982-6915.

Is Your Q4 e-tron Losing Range Faster Than the Weather Explains, and What Will a Lawyer Ask?

A step drop in full-charge range can point to a failing module or charging path. So can charging that stops short, a high-voltage warning or lost drive power. Slow seasonal fade, by contrast, matches the gradual capacity loss Audi's FAQ describes. A lawyer asks which pattern your car shows.

Put the symptom on each repair order in your own words, as in these examples.

• The full charge shows far fewer miles than it did last week.
• Charging quits before it reaches the target.
• A high-voltage battery warning is on the cluster.
• The car lost drive power with charge left in the pack.
• The gear position is missing from the instrument panel.
• The outlet or cable was hot after an overnight 240-volt session.

Say you commute on Interstate 5 from Oceanside to Sorrento Valley, and the range falls more each week. That pattern, logged with dates, gives the technician a condition to test.

Slow Seasonal Fade or a Module Giving Out

A failing module tends to announce itself with a sharp drop, a warning or a charge that stops early. Audi's service action 91FN reaches certain 2022 and 2023 Q4 e-trons whose battery cells may show increased self-discharge. Under the revised 91FN dealer bulletin, dealers update battery software, evaluate the battery and replace affected cell modules. Audi labels it a service action, not a recall, but each module swap is a dated repair attempt.

Every Charger Fails, Not Just the One in the Parking Lot

A failed session does not always mean the car is at fault, because public stations break and home circuits trip. If sessions fail at one Kearny Mesa station but succeed everywhere else, the station is the likely problem. If the Q4 refuses to charge at home, at work and in public, the car becomes the common factor. Photograph each error message with the charger and the time.

Which Model Years and Warranty Clocks Does an Audi Q4 e-tron Lemon Law Lawyer Check?

Every Q4 e-tron is a 2022 or later model, since fueleconomy.gov first lists it for 2022. Audi's EV FAQ gives e-tron vehicles from model year 2021 onward 8 years or 100,000 miles of battery coverage, whichever occurs first. Audi's certified pre-owned booklet lists the New Vehicle Limited Warranty at 4 years or 50,000 miles, whichever occurs first.

Say you bought a 2022 Q4 new, and a module fault appears in year six at 70,000 miles. The basic warranty ended years earlier, but the battery warranty may still run. Charging hardware and the 12-volt system generally sit under the basic term, unless your booklet says otherwise. EPA figures are estimates from testing new vehicles, not a range promise.

Which NHTSA Campaigns Should an Audi Q4 e-tron Lemon Law Lawyer Match to Your VIN?

NHTSA's recall file, pulled September 30, 2026, lists seven campaigns reaching the Q4 e-tron. Campaign 25V125000 involves drive power. The filing says the on-board charger may fail and stop charging the 12-volt battery, which can result in a loss of drive power. Such a fault may be likely to cause death or serious bodily injury, where two repairs can matter.

Say your 2024 Q4 shuts down on State Route 78 near San Marcos. The first visit ends with a new 12-volt battery, then it quits again. Under 25V125000, dealers replace the on-board charger, another dated attempt.

When the 12-Volt Battery Goes Flat Beside a Full High-Voltage Pack

A Q4 still carries a 12-volt battery for its electronics, and the on-board charger keeps it charged. When that path fails, the car can lose drive power with charge left in the main pack. Audi lists service campaign 93OE, a software update to help improve on-board charger performance on certain 2024 Q4 e-trons. Campaigns 25V120000 and 25V125000 reach the Volkswagen ID.4 too, and the firm tracks Volkswagen ID.4 claims alongside the Q4.

Audi Q4 e-tron Complaints in the NHTSA Data

NHTSA's complaint file, pulled September 30, 2026, holds 70 owner complaints about 2022 through 2025 Q4 e-tron models. The electrical system appears in 44 of them. These are owner reports rather than findings of a defect. They also give counts and categories, not diagnoses, so your own repair orders still carry the claim. The categories overlap, since one complaint can name several systems.

If the Pack Tested Fine but the Q4 Will Not Hold a Charge, What Does a Lawyer Need on the Order?

A note that the battery tested normal may mean only the high-voltage pack was checked. Ask that the technician also test the on-board charging components and the charge port. Then ask that the order list each test, its result, any fault codes and the battery health report.

Say you bring a three-week range log, and the technician runs only a pack test. That order leaves the charging path unexamined. Ask for a corrected order before you leave. Even a could-not-duplicate result shows you reported the defect while the warranty ran.

What Your Range Log Should Show Before the Next Visit

Record the range shown after each full charge, with the date. Next to it, note the outside temperature and whether you preconditioned the battery. Audi advises preconditioning while plugged in to limit the effect of very hot or cold weather. Photograph any warning with the date and odometer visible, and note each session that stopped early. Bring it to every visit.

Printouts and Software Notes to Ask for at Pickup

Request a printed copy of any fault codes and any battery health report the technician ran. If the dealer updated software, ask that the order name the module, the software version and the reason. A visit that reprograms a module to address your complaint is a repair attempt on the record. Those entries turn a vague complaint into dated proof.

Can a Lawyer Call a Q4 e-tron a Lemon After a Second Module Replacement?

It can, depending on the orders. Inside 18 months or 18,000 miles, whichever comes first, Civil Code section 1793.22(b) creates a presumption. It treats Audi as having had a reasonable number of repair attempts in three situations. After that window, Audi lemon law claims rest on whether fixes kept failing after a fair number of tries.

Say your 2022 Q4 reaches 61,000 miles in year four, and the dealer replaces a battery module for a capacity fault. Three months later it replaces a second one, and the warning returns. Two failed module repairs may be enough, depending on the downtime and how the fault limits your driving.

The 18-Month Presumption and a Long Parts Wait

Under section 1793.22(e)(1), a nonconformity means a defect substantially impairing the Q4's use, value or safety. Route one covers two or more repairs of a nonconformity likely to cause death or serious bodily injury. Route two covers four or more repairs of the same nonconformity. Both need at least one direct notice to Audi itself if the warranty or manual clearly disclosed that duty. The third route needs no direct notice. It counts more than 30 cumulative days out of service for repair, and only conditions beyond Audi's control stretch that count. A long module wait can move a Q4 toward it.

The presumption can be rebutted, and outside the window a claim can still win on the full repair history. Separately, Civil Code section 1793.2(b) says each repair must be finished within 30 days. Only a written agreement from you, or a delay Audi could not control, extends it.

Audi Q4 e-tron Leases, CPO Battery Exclusions and Rodriguez

A lessee, the person who leases, stands where a buyer would under Civil Code section 1795.4. Audi's certified pre-owned booklet says the certified warranty does not cover the high-voltage battery or battery module. The original New Vehicle Limited Warranty might still cover them if that coverage remains. Rodriguez v. FCA US, LLC (2024) 17 Cal.5th 189 treats a used car as new only when the manufacturer's new car warranty was issued with that sale, not because factory coverage is left over. The court did not rule on certified programs, so a certified Q4 usually sits outside the new-vehicle remedy, and that stays unsettled.

What a Q4 Buyback Returns and When the Four-Year Clock Runs Out

A buyback, called restitution in the statute, refunds the price paid or payable, along with taxes and official fees. Incidental costs like a tow or rental come back too. Audi can deduct a mileage offset, which charges for miles driven until the first repair visit for that defect. A $52,000 Q4 first taken in at 12,000 miles may carry a $5,200 offset, as arithmetic only. Run your figures in the buyback calculator.

As of September 30, 2026, Audi was absent from the Department of Consumer Affairs list of manufacturers that chose the newer lemon law procedures. Its claims therefore run under Commercial Code section 2725, which gives four years, usually from tender of delivery. An exception applies when a warranty explicitly extends to future performance and discovery must await that performance. The clock then runs from when the breach is or should have been discovered, and an 8-year battery promise may qualify. Leases may fall under Commercial Code section 10506, also four years. For a Q4 sold new in 2026 or later, section 871.29(d) requires Audi to name the governing procedure at the sale.
