It felt like a was reared ended, my car came to just about a complete stop. It then began to shake and would not accelerate past 5mph to get me over to the side of the road. The check engine light came on. On 2/28/2026 my engine came on, I took it to Kia and they replaced my spark plugs, I got my vehicle back on 3/10/2026. At the beginning on 2026, Kia had my car for over a month for the same engine issues but said nothing is wrong with the vehicle. Back in December 2024 I had this exact issue of the car jolting and stalling. Kia said it was the transmission. I paid to have that replaced but it seems the vehicle is still having all of the same issues. My life was put at risk driving this 2021 Kia Seltos. I am very lucky that the cars around me were paying attention and did not crash into my car that came to a complete stop with vehicles going 65 around me. Others lives could have been at risk had they crashed into my car. My car is once again back at Kia, with the engine light on again.” (NHTSA Complaint #11723933)

Owner reports include: “My engine was replaced April 9. 2025 because of piston issues. I had taken it in a few weeks prior for terrible grinding noise, shaking, and slowing down. They didn’t find anything wrong. It happened for a short time twice after and didn’t take in as sporadic and would stop. Then it happened again for longer time. I had it towed to Kia again. During time in shop, I received a recall letter. Shop kept saying it would be done next day. After a few days I called and they said they were putting in an engine. I Picked it up and then two weeks before Christmas It started grinding sound and shaking etc. It was towed into Kia I bought from as my Kia roadside had expired a few days before. They ran diagnostic test and said they found nothing. I told they to try harder. Ran another test and supposedly according to some bulletin they upgraded some software back to what it was before engine replaced and the problem should be fixed. Only drove car 1 mile according to service papers I have. I have a 5 year old car with 24,000-25,000 mi. on and I am afraid to drive it. So far it has only happened when driving 45 mph or less. I will not drive it on turnpike or interstate. I want this recorded someplace so it is on the record for other with this issue.” (NHTSA Complaint #11719683)
Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2021 Kia Seltos have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 26 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “Engine stalled at stoplight. Was able to restart and pulled into closest parking lot where it began idling hard. Check Engine light turned on. Checked oil and it was bone dry (no signs of oil leak/burning beforehand). After adding about a quart of oil, while in park I revved the engine slowly, but it would stall out if it went over 3000 rpms and idle even harder. My basic code reader popped for P0014 and P0017 (crankshaft/camshaft position). Had to have it towed to the local dealer for safety. 75,400 miles on it and my VIN has not been part of recalls. Requesting an investigation to include more VINs as these issues point to a prior recall resulting in engine replacement.” (NHTSA Complaint #11722774)

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2021 Kia Seltos:
Once the presumption is triggered, the burden shifts to Kia to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Kia must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2021 Kia Seltos qualifies as a lemon under California law, Kia may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Kia a reasonable opportunity to fix the defect. Visit different authorized Kia dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Kia pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Kia a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Kia is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
