Tesla vs Hyundai Lemon Law Problems: What California Owners Report

Which has more lemon law problems in California, Tesla or Hyundai?

Side-by-Side Comparison

The Tesla Complaint Picture in California

For 2019 to 2027 model years, California Tesla owners sent NHTSA 2,486 complaints between 2021 and 2026. Collision warning and driver-assist systems were named most often, in 594 complaints. Steering followed with 258, brakes with 243, the electrical system with 240 and speed control with 186.

The Model Y is the center of the Tesla data, with 1,165 complaints. The Model 3 had 915, the Model X 193, the Model S 155 and the Cybertruck 57. Owners in Los Angeles filed 157, San Jose 121, San Diego 106, San Francisco 90 and Irvine 57.

Because Tesla builds only electric vehicles, its list has no engine or transmission category near the top. The reported trouble sits in the systems that sense the road and react to it. That is a different starting point from a brand that sells gas, hybrid and electric models side by side.

The Cybertruck number is small because it is a newer model with fewer owners so far, not because it has been studied less. As more owners take delivery, its share may change. If you own a newer Tesla with little public data, your claim still works the same way: it rests on your own service history and your own description of the defect.

The Hyundai Complaint Picture in California

Hyundai owners filed 1,104 California complaints for the same model years and dates. The electrical system was the top area by a wide margin, with 294 complaints, more than a quarter of the brand total. The engine followed with 163, then brakes with 99, collision warning and driver-assist systems with 79, and transmission and powertrain with 78.

The Hyundai Ioniq 5, an electric crossover, drew more complaints than any other Hyundai: 278, about a quarter of the total. The gas-powered Hyundai Palisade (134), Hyundai Tucson (115), Hyundai Elantra (94) and Hyundai Santa Fe (78) came next.

Los Angeles (60) and San Diego (59) led Hyundai's city list, and the Inland Empire showed up strongly too, with Riverside at 22. Sacramento (19) and San Francisco (16) rounded out the top five. Hyundai's mix of EV and gas models means its electrical complaints can come from very different vehicles, so look at your own model rather than the brand total.

Engine complaints, the second-largest Hyundai category with 163, come from the brand's gas models rather than the Ioniq 5. That is a reminder that one brand total can mix very different problems. A Palisade owner with an engine issue and an Ioniq 5 owner with a charging fault are both Hyundai owners, but their claims look nothing alike.

Model Y and Ioniq 5: Two EVs, Two Complaint Profiles

The most direct comparison on this page is between the two EVs that lead each brand's list. Model Y owners filed the most Tesla complaints, and Ioniq 5 owners filed the most Hyundai complaints. Both are electric crossovers sold to many of the same California households.

The categories behind them differ. Tesla's top category is driver assist. Hyundai's top category is the electrical system, and for an EV that can include the parts that charge the battery and power the car. Neither pattern tells you how your own vehicle will behave.

For an EV lemon law claim, describe symptoms clearly: a charging failure, a warning followed by reduced power, or the car refusing to shift out of park. A problem that cuts power while driving can be a safety defect, which matters for the two-repair path of the presumption in Civil Code 1793.22(b).

If you want background on EV range and efficiency, the federal fueleconomy.gov site lists ratings for both models. That information is useful context, but a range shortfall alone is a different question from a warranty defect, so ask an attorney how your specific issue fits.

Software plays a role for both brands. Tesla pushes updates over the air, and many newer Hyundai models can also receive updates, sometimes at the dealer. Whenever an update is meant to address your complaint, note the date and what it was supposed to fix, and whether the problem came back.

Who the Claim Is Against and Where Records Come From

A Tesla claim names Tesla, Inc. Tesla sells and services mostly through its own service centers, so the company that will answer the claim also wrote your service records. Keep every work order and invoice, including mobile service visits, and keep a note of each over-the-air update that was supposed to address your complaint.

A Hyundai claim names Hyundai Motor America. Hyundai repairs go through franchised Hyundai dealers, so the dealer writes the repair order and the manufacturer receives the warranty claim. Ask for a copy of every repair order, even when the dealer says nothing was wrong.

With either brand, your copies are the backbone of the case. Under Oregel v. American Isuzu Motors (2001), you do not have to prove the exact technical cause of the defect, and visits where the problem could not be found or fixed can still count. That only helps if the visit is written down.

If you bought either car from a dealer or the brand with financing, keep the retail installment contract too. A buyback refunds the price paid or payable, including collateral charges like sales tax and registration, so the contract is where those numbers come from.

• Tesla: service center and mobile work orders, invoices, update notes
• Hyundai: dealer repair orders with dates in and out and mileage
• Both: purchase or lease contract and financing papers
• Both: rental, towing and charging receipts tied to repair days

The 30-Day Clock When an EV Waits for Parts

California sets a time limit on warranty repairs. Civil Code 1793.2(b) says repairs must be completed within 30 days unless the buyer agrees otherwise. Separately, the presumption in Civil Code 1793.22(b) applies when the vehicle has been out of service for repairs more than 30 days total within 18 months or 18,000 miles.

EV parts can take time to arrive, whether a car is at a Tesla service center or a Hyundai dealer. Every one of those days counts. Ask that the repair order show the date you dropped the car off, not only the date work began, and the date you got it back.

Those waiting days also cost money. Under Civil Code 1793.2(d)(2)(B), a buyback includes incidental damages such as reasonable towing and rental car costs. Save every receipt, including rideshare rides you needed because the car was in the shop.

A loaner or rental does not stop the clock. The car is still out of service for repairs, even if you had something else to drive. Keep a simple calendar that marks each day your EV was at the shop, and match it against the dates on each repair order. If the dates disagree, raise it with the service advisor right away while memories are fresh.

Example: An Ioniq 5 That Loses Power

This is a made-up example. Lena bought a new 2023 Hyundai Ioniq 5 in Riverside. At about 6,000 miles, a warning appeared on the dash and the car slowed to a crawl on a busy road. It was towed to a Hyundai dealer, which replaced a charging component.

Four months later the same warning returned and the car again lost power. The dealer kept it 19 days while waiting for a part. A third event followed, and the car sat another 14 days. Lena kept every repair order, her tow receipts and her rental bills.

Her attorney noted two paths under the presumption: a defect likely to cause serious injury repaired 2 or more times, and more than 30 days out of service. The attorney checked whether her owner's manual required direct notice to Hyundai Motor America, then sent a repurchase demand under Civil Code 1793.2(d)(2). This illustration does not predict any real result.

Lena did not have to explain why the charging part kept failing. Her job was to report the problem, give the dealer a chance to fix it, and keep the records. The technical cause was for the manufacturer to figure out. Throughout, she kept making her loan payments so the claim would not be complicated by credit problems.

Reading the Numbers Fairly and Taking the Next Step

Tesla's 2,486 complaints are more than double Hyundai's 1,104, but that gap is not a quality score. Raw complaint counts are not adjusted for how many vehicles each brand has sold in California, and owners of different brands report problems at different rates. NHTSA does not verify the complaints it receives from owners.

The useful part of the data is the pattern: what kinds of problems owners of each brand report and which models come up most. If your problem matches the pattern, that is worth knowing. If it does not, your claim is just as valid.

When the same defect keeps coming back, call for a free case review. You pay $0 out of pocket, and if you win, Civil Code 1794(d) makes the manufacturer pay your attorney fees and costs. Keep making your loan or lease payments while the claim is open.

Before you call, gather what you have: the contract, the repair orders and a short timeline of when the problem started. An attorney can usually tell you quickly whether the history already fits the presumption or whether the case depends on other evidence. If your Tesla or Hyundai was sold to you as a used car, mention that too, because the rules can be different.

Signs Your Tesla May Qualify

• Your Tesla has been in for the collision warning and driver-assist systems 2 or more times and it is a safety issue
• The same Tesla problem has been repaired 4 or more times
• Your Tesla has been out of service more than 30 days for warranty repairs
• You own a Tesla Model Y and the problem keeps coming back

Signs Your Hyundai May Qualify

• Your Hyundai has been in for the electrical system 2 or more times and it is a safety issue
• The same Hyundai problem has been repaired 4 or more times
• Your Hyundai has been out of service more than 30 days for warranty repairs
• You own a Hyundai Ioniq 5 and the problem keeps coming back

Key Facts (as of October 2026)

• Complaint counts are California owner reports to NHTSA for 2019 to 2027 model years, filed 2021 to 2026. They are not verified defects and are not adjusted for sales.
• The two brands' top problem areas differ: Tesla owners report the collision warning and driver-assist systems most, Hyundai owners the electrical system.
• For either brand, a reasonable number of repair attempts is presumed within 18 months or 18,000 miles after 2 tries for a serious safety defect, 4 tries for the same defect, or more than 30 days in the shop (Civil Code 1793.22(b)).
