My Car Has Electrical Problems That Keep Coming Back. Is It a Lemon?

The Short Answer

Signs Your Electrical Problem May Qualify

• The same electrical problem, or a cluster of related ones, has returned after repairs
• Warning lights appear for systems that seem to be working, or several warnings appear at once
• Lights, locks, windows, wipers, gauges or the screen act on their own or stop working
• The battery keeps draining, or the car will not start without a jump
• The dealer has replaced modules, wiring or the battery, or updated software, more than once
• The car is under the new car warranty, or the problems started while it was

Why Electrical Problems Are So Common in New Cars

A modern car can have dozens of computer modules talking to each other over a network of wires and connectors. They control the engine, transmission, brakes, lights, locks, windows, climate, screens and driver assistance systems. When one module, one connector or one software file has a problem, the symptoms can show up in places that seem unrelated.

That is why electrical defects often look like a string of small issues. One week the windows will not roll down. The next week the headlights flicker and a parking sensor warning appears. Then the car will not start. Dealers sometimes treat each one as a new, separate concern, and owners wonder whether any of it adds up to a lemon.

It often does. A lemon law attorney looks at the whole history, and a pattern of electrical faults that keep returning can show a single underlying defect, or several, that the manufacturer has not fixed.

Water leaks, rodent damage and aftermarket wiring can all cause electrical faults too, and a manufacturer may raise them. If your car has had a leak, a flood or an accessory installed, tell the dealer and your attorney up front. Honest disclosure early is better than having the manufacturer find it later.

Electrical faults can also arrive with a dead 12-volt battery, which is often the first thing the dealer replaces. If the car keeps draining batteries, the battery may not be the cause. A module that stays awake, a short in a harness or a faulty accessory circuit can all drain a good battery overnight. Ask the dealer whether they ran a draw test, and ask that the result be written down.

How the Lemon Law Applies to Electrical Defects

California's lemon law is the Song-Beverly Consumer Warranty Act (Civil Code 1790 and following). It protects owners of new and leased vehicles when a warranty defect that substantially impairs use, value or safety is not fixed by the manufacturer or its dealers after a reasonable number of attempts. If that standard is met, the manufacturer must replace or repurchase the vehicle, and the buyer may choose the buyback (Civil Code 1793.2(d)(2)).

The Tanner Act presumption in Civil Code 1793.22(b) covers the first 18 months or 18,000 miles, whichever comes first. A reasonable number of attempts is presumed if the same defect was repaired four or more times, or the car was out of service more than 30 total days. If the electrical defect is likely to cause death or serious bodily injury, such as headlights that shut off at night, airbag faults or a car that powers down while driving, two repair attempts can be enough. If the owner's manual clearly says to notify the manufacturer directly, that notice is a condition of the repair-count paths.

Outside that window, you can still have a claim if the defect first appeared under warranty and the manufacturer had a fair chance to fix it.

Intermittent Problems and 'No Fault Found' Visits

Electrical problems are often intermittent. The car may behave perfectly the day you drop it off. The technician connects a scan tool, finds stored codes or nothing at all, and returns the car. Owners leave feeling like they wasted a trip.

Those trips matter. In Oregel v. American Isuzu Motors (2001), a California appeals court ruled that a buyer need not prove the exact technical cause of a defect, and that repair visits where the dealer could not find or fix the problem may still count. Each visit is a chance the manufacturer had to fix the car.

To get the most from each visit, bring photos of the warning messages and your log. Ask the dealer to record any stored codes on the order, even if they could not reproduce the symptom. If the car needs to stay overnight so the technician can test for a battery drain, agree to it if you can, and ask for a loaner.

Write down how the problem affects your daily life too. A car that will not lock at night, a window stuck open in the rain, or wipers that quit in a storm are more than glitches. Those details help show that the defect substantially impairs the use of the car, and they help a dealer understand why the repair matters.

What to Make Sure Is on Each Repair Order

Because electrical problems spread across many systems, a complete repair order is especially important. Read it before you leave, and ask for corrections if something is missing.

• Every symptom you reported, not only the one the technician worked on
• Stored trouble codes, printed on the order
• Parts replaced, such as a module, harness, connector, sensor or battery
• Software updates, by name or version if possible
• Dates in and out, so days out of service can be counted
• A note that this is a repeat concern, with a reference to the earlier visit

Software, Recalls and Repairs That Count

Many electrical fixes are software. Dealers reflash modules, and many cars now receive over-the-air updates. Our firm's view is that a software update, even one pushed over the air, can be a repair attempt when it was aimed at the problem you reported. Take screenshots of update notices and note the date.

Recalls also come up often with electrical defects. Recalls are manufacturer safety repair programs, and a recall repair can count as a repair attempt. Run your VIN through the NHTSA recall lookup. A technical service bulletin is a repair instruction to dealers for a known issue, not a safety recall, but if one is used on your car, ask that the order say so.

Work done by an independent shop, or by you, does not count as a repair attempt under the lemon law. Aftermarket electronics, such as remote starters, dash cams wired into the fuse box or added lighting, can also give the manufacturer an argument that something other than a defect caused the problem. If you have added anything, tell your attorney so it can be addressed early.

Some electrical repairs take time because a module must be ordered or programmed. Repairs generally must be completed within 30 days unless you agree otherwise (Civil Code 1793.2(b)). Count the days the car sits at the dealer, and keep the rental or rideshare receipts from those days.

Example: A Pickup With a Long List of Glitches

What follows is an invented scenario, not a real case. Robert bought a new pickup in Stockton. In the first three months, the power windows stopped working twice, the instrument cluster went dark once on the freeway, and the truck would not start one morning. Each time, he took it to the dealer.

The first two repair orders listed only the windows and a battery test. On the third visit, Robert brought a one-page log of every symptom and asked the advisor to list all of them. The technician found a corroded ground connection and replaced a body control module. A month later the cluster flickered again, the headlights cut out briefly at night, and a software update was performed.

Robert called a lemon law attorney with four repair orders, his log and photos of the dash. The attorney reviewed whether the symptoms pointed to the same electrical defect and contacted the manufacturer. This example shows the process only. No result is implied.

His log was the most useful thing he brought. It tied scattered symptoms together by date and showed how often the truck was affected.

Robert also kept every repair order in date order and wrote the mileage on a sticky note on each one. That simple step made it easy to count how many times the truck had been in for electrical work and how many days it had spent at the dealer.

Refunds and Who Pays for the Lawyer

Should the manufacturer repurchase the car, restitution is the actual price paid or payable, including collateral charges like sales tax, license and registration fees, plus incidental damages such as reasonable repair, towing and rental car costs (Civil Code 1793.2(d)(2)(B)). The manufacturer can subtract a mileage offset based on the miles driven before you first brought the car in for the problem (Civil Code 1793.2(d)(2)(C)). The numbers depend on your contract and dates, so every case is different.

The manufacturer pays attorney fees and costs when the buyer wins (Civil Code 1794(d)). With us, there is nothing to pay out of pocket, and a case that does not win leaves you owing us nothing.

Keep paying your loan or lease while the claim is open. Missed payments can hurt your credit and lead to repossession. If you are thinking about trading in the truck or car, talk to your attorney first.

Timing matters as well. Warranty claims are generally subject to a four-year statute of limitations (Commercial Code 2725), and when that period starts can be technical. If you have a long list of electrical problems and the warranty is close to ending, a free case review now can keep your options open.

What to Do Next

1. Each time a problem appears, photograph the dash and any warning messages, and note the date, mileage and conditions.
2. Keep a simple log that lists every electrical symptom, even small ones, in one place.
3. At the dealer, describe every symptom on the same visit and ask that each one be written on the repair order.
4. Ask that any module replacement, wiring repair or software update be listed by name.
5. Keep all repair orders, tow receipts and rental receipts together.
6. Call 877-536-6620 for a free case review and walk through your log with an attorney.

Key Facts (as of October 2026)

• Within 18 months or 18,000 miles, a reasonable number of attempts is presumed after four repairs of the same defect, more than 30 total days out of service, or two repairs of a defect likely to cause death or serious injury (Civil Code 1793.22(b)).
• A recall repair, which is part of a manufacturer safety program, can count as a repair attempt.
• Keep making loan or lease payments during a claim, because missed payments can hurt your credit and lead to repossession.

FAQ

Do different electrical symptoms count as the same defect?

They can, if they come from the same underlying cause, such as a faulty module or wiring problem. A lemon law attorney will look at the pattern across your repair orders.

The dealer could not find anything. Should I still go back?

Yes. Go back each time the problem returns, because visits where the dealer could not find the problem can still count.

Can aftermarket accessories hurt my claim?

They can give the manufacturer an argument about the cause. Tell your attorney about anything added to the car so it can be addressed.

Is a headlight that shuts off at night a safety defect?

It can be, because losing headlights while driving at night creates a serious risk. Ask that the repair order describe it in those terms.
