Hello everyone, my name is Sonny Miller and I’ve been in the car business for over 20 years.
If you’re on this page, you’re probably trying to sell your car that failed the smog test in Southern California. So I wanted to go over some things with you guys about getting the most money for your vehicle that failed the smog test.
If you’re ready to sell right now, just call me directly at (714) 900-3723. I’ll give you a fair cash offer over the phone. But if you want to learn more about all your options first, keep reading.
We’re gonna go over 4 ways to sell your car that failed the smog test later in this post. But before then, let’s go into some reasons why your vehicle will fail the smog test in the first place.
Why Your Vehicle Will Fail the Smog Test
The most common reason is because your vehicle has a check engine light. Basically, this is telling you that there’s something wrong with your vehicle.
Now, this might be an easy fix that you could do yourself. But first, there are two different kinds of check engine lights:
- Flashing check engine light — this is severe.
- Solid check engine light — this might not be so bad.
Here’s an example of what a failed smog inspection report looks like — notice the OBDII trouble codes listed at the bottom. These are the codes that tell you exactly why your vehicle didn’t pass:
How to Diagnose the Problem Yourself
So it’s smart to check what is wrong with your vehicle. Here’s how you do it: you use an OBD2 scanner, which stands for On-Board Diagnostics Second Generation.
This plugs into your vehicle’s port underneath the steering wheel, above the gas pedal and brake pedal. Once you plug this device into your vehicle, it tells you what’s going on. Specifically, it will give you codes, and these codes will tell you exactly what’s wrong.
Here’s what an OBD2 scanner looks like — this is the same type of device that any auto parts store will use to scan your vehicle for free:
In this video, I show you exactly how to use an OBD2 scanner step by step on a 2002 Toyota Sequoia — where to find the port, how to plug it in, how to read the code, and then how to look it up online to find out what’s wrong:
Where to Get an OBD2 Scanner
They’re relatively cheap. For example, you could pick one up at Walmart for like $30 to $40, and they’re easy to use too. It will give you a sequence of codes — letters and numbers — and then you could just Google them. That will give you a good idea of what’s going on with your vehicle.
Alternatively, you could get your vehicle scanned for free at any major auto parts store such as AutoZone, O’Reilly Auto Parts, or Pep Boys. You could go there and they’ll scan it and give you a printout totally free.
It Might Be a Cheap Fix — or It Might Not
Once you know what’s going on with your vehicle, it might be an easy fix to make your car pass the smog test. For instance, it could be as simple as a gas cap that needs to be replaced — that’s only like $15 to $20.
However, it can also be expensive to fix. Depending on the code you get back, it will tell you the severity of the problem. It could be as simple as $20, or it could be as expensive as thousands of dollars.
As a result, if your car failed the smog test, you might not want to throw thousands of dollars into it if you’re not planning to keep it. If that’s where you’re at, you might want to look into selling your old car for cash instead.
Legal and Paperwork You Need to Know
Next, let’s go over some legality and paperwork you’re going to need to sell your car that is in this state.
You’re going to want to make sure all your paperwork is in order to get the most for your vehicle. The reason I’m speaking on this is because you’re going to need to know how to navigate the DMV system. Specifically, the most you could get for your vehicle is selling the car private party — but there are legalities involved.
Planned Non-Operation (PNO)
If your car failed the smog test, it’s not that simple to sell it to somebody private party. Instead, you’re going to have to make sure your car, truck, or SUV is in Planned Non-Operation, which tells the DMV that you’re no longer operating the vehicle. It is not driving on the streets. You can file for Planned Non-Operation on the California DMV website.
As a result, you cannot test drive the vehicle.
“Sold As-Is” Does NOT Protect You
In other words, just because you write “sold as is” on a bill of sale does not mean it is truly sold as is — unless the vehicle is completely out of your name.
So when you sell your vehicle private party, make sure you do it at a DMV office, AAA office, or a registration service office. Otherwise, you run the risk of an incomplete transfer. Make sure that the vehicle is completely out of your name. In addition, if you need help with the title transfer paperwork, we put together a step-by-step guide to completing Form REG 227.
The Release of Liability — Don’t Skip This Step
In this video, I walk you through the Notice of Release of Liability on your pink slip — how to fill it out, why you should do it online at DMV.gov, and how it protects you from parking tickets, tow yards, and even hit-and-runs coming back in your name after you sell:
Why Most Car Buying Companies Won’t Buy Your Smog-Failed Vehicle
Before we get into your 4 options, there’s something I want you guys to know. If you’ve been trying to sell your car to the big companies like Carvana, AutoNation, or Driveway — they’re not gonna buy it. These companies want clean, retail-ready vehicles they can put right on their lot or their website. A car with a Check Engine Light or a failed smog test doesn’t fit their model, so they’re gonna pass on you.
That’s exactly why we started goCarBuyer. Unlike those companies, we specifically buy vehicles that failed the smog test. We see the value in your car even when it can’t pass emissions. We also buy cars without a title and salvage title cars that other buyers reject. We don’t need a smog certification, we handle all the paperwork, and we come directly to you. It’s that simple.
Your 4 Real Options to Sell a Car That Failed the Smog Test
Here’s a quick side-by-side so you can see how your options — along with some of the bigger companies — compare before we break each one down:
Quick Comparison of Your Options
| Option | Time to Get Paid | Typical Offer | Hassle Level | Best For |
|---|---|---|---|---|
| Private Party | Weeks to months | Highest (but risky) | High – scammers + paperwork | People with time & clean title |
| CAP State Program | 1–2 months | $1,350 / $1,500 / $2,000 | Medium – strict rules | Low-income, running cars |
| Junkyard | Same day | Scrap value only | Low | Non-running vehicles only |
| goCarBuyer (Recommended) | Same day | Fair cash (beats junkyard) | None | Anyone wanting fast cash, no hassle |
Option 1: Sell Your Car Private Party
You can put your vehicle online for sale. Just make sure to mention that it failed the smog test and it’s on Planned Non-Operation. This is very important — tell the customers upfront so they know what they’re getting.
Don’t expect a premium price for it.
You want to use platforms such as Facebook Marketplace, Craigslist, and OfferUp. Give a description of the vehicle, and then take photos of it. I highly suggest taking photos of the miles and taking about 30 to 40 photos total.
Moreover, please remember — this only works if your vehicle is on Planned Non-Operation through the DMV.
Beware of Scammers on These Platforms
Also, watch out for scammers. I’m not saying these platforms are a scam. I’m just saying there are a lot of scammers who use these platforms to trick you into giving up your identity. They’ll send you links to VIN verifications. On top of that, they’ll ask you normal questions just like any other customer would, and they’re very tricky.
Therefore, if anyone tries to send you any links, be very cautious — especially anything involving VIN verification or anything asking you to pay with your debit card or credit card.
Additionally, if you’re going to meet any potential customers, remember: if you put your vehicle on Planned Non-Operation, you cannot test drive it. Keep that in mind.
Option 2: The State Buyback Program (CAP)
The Consumer Assistance Program, also known as CAP, is a state-run buyback program offered by the California Bureau of Automotive Repair. Although this program is good, it can be a little tricky to navigate.
Generally, they’ll pay you either $1,350, $1,500, or $2,000 depending on your income.
However, there are some things to know about this program:
- Your registration must not have lapsed for more than 120 days — otherwise you’ll get turned down.
- Your vehicle must drive to the state-contracted dismantler under its own power.
- In addition, the state requires that it starts without a jump start and moves forward at least 10 yards.
- If it needs a tow or the transmission is not working, it won’t be eligible.
- Furthermore, this program can take months to get paid.
If you think you qualify, you can apply for the CAP program online here.
Option 3: Sell to a Junkyard
You can sell to a junkyard such as LKQ Pick Your Part or any dismantler that buys vehicles in this state that failed the smog test.
Now, you’re not going to get the most for your vehicle. They don’t pay you much — they only give you scrap value. In fact, even if your car is still running decent, it does not matter to them.
Nevertheless, it can be an option depending on your vehicle’s condition, but it might not be the best option. Most people hate junkyard lowballs — that’s why a lot of our customers call us instead and get a much better offer the same day.
Option 4: Sell to Us Instead
We pay you cash on the spot for your vehicle that failed the smog test in Southern California. Additionally, we handle all the paperwork. You do not need to go and put your vehicle in Planned Non-Operation to sell to us.
On top of that, we will give you more than the junkyard. We see the value in older vehicles. Whether it’s a high-mileage daily driver, a classic car, a work truck, or even a cargo van, we buy it all.
Whether you’re in Orange County, Riverside County, Los Angeles County, San Diego County, Ventura County, or San Bernardino County — we come to you in hours and work with your schedule. We come to your home, office, storage, or wherever you would like to meet.
Most importantly, we do the transaction really quickly. We take out the headache of selling your vehicle that failed the smog test.
Failed Smog Looks Different Depending on Your County
California’s Smog Check program actually changes depending on where you live. Some counties are Enhanced areas — the strictest tier the state runs, with STAR-certified station rules if your car gets flagged.
Others are mixed, where the rules shift from one ZIP to the next inside the same county. So I wanted to break down what you’re up against in each of the six counties I cover, and how I can help you no matter which one you’re in.
Failed Smog in Orange County
Orange County sits in an Enhanced Smog Check area, so the testing rules out here are some of the toughest in the state.
If your car failed bad enough to get flagged as a gross polluter, you can’t just take it to any shop for the re-test. You’ve got to go to a STAR-certified station, pay for the repair, then pay again for the re-test, and hope it passes the second time.
I’ve talked to a lot of folks in Anaheim, Santa Ana, Huntington Beach, and Irvine who poured real money into chasing that certificate and still couldn’t get there.
So when you’re ready to stop throwing cash at it, I come to you anywhere in OC — your driveway, your work, your storage spot, wherever you are. No PNO on your end, no STAR station, no re-test. I pick up personally and pay cash on the spot. → See our Orange County service area
Failed Smog in Los Angeles County
LA County is also an Enhanced area, so you’re in the same strict tier as Orange — but the scale’s different out here.
There are more than 250 STAR-certified locations spread across the county, just because LA is that big and the program needs that many to cover everybody.
Sounds like a lot until you realize you’re probably driving halfway across the city to find one that can fit you in this week, and then driving back again if it doesn’t pass the first time.
So if you’re in Long Beach, Lakewood, Glendale, the Valley, or down in the South Bay, that runaround adds up fast in time and gas before you’ve even paid for the repair.
I’m a Southern California resident just like you, and I know the traffic out here is a tax on top of everything else. One call to me and I come to you — cash in hand, paperwork done, same day. → See our Los Angeles County service area
Failed Smog in Riverside County
Riverside is one of those counties where the smog rules actually change depending on where you’re at in it.
Down in the western valley — Riverside, Corona, Moreno Valley, Jurupa Valley, Temecula — you’re in an Enhanced area, with the same tough testing and STAR station situation as OC and LA.
But head east toward the desert and the designation can be different, so before you spend a dime on repairs it’s smart to look up your own ZIP on the state’s locator just to be sure what tier you’re in.
Either way the math usually lands the same place. If the repair to pass smog costs more than the car’s worth to you, fixing it stops making sense.
So I drive out to the valley and the desert both — just call me, I’ll give you a ballpark figure over the phone, and if it works for you, I come out same day. Cash, check, or Zelle on the spot. → See our Riverside County service area
Failed Smog in San Bernardino County
San Bernardino is a big county, and the smog program is genuinely split inside it.
Down in the valley — San Bernardino, Fontana, Ontario, Rancho Cucamonga, Chino — you’re in an Enhanced area, so the tougher testing and the STAR requirement for flagged vehicles applies just like in OC.
But up in the High Desert around Victorville, Hesperia, Apple Valley, and Barstow, the designation can be different, so I’d check your specific ZIP before you sink money into shop quotes.
That detail matters because if you’re sitting on a vehicle that won’t pass, you might be paying for repairs you don’t strictly need. Or you might be stuck with something that can’t be registered until it’s certified.
Either way, when you’re ready to let it go, I drive out to both the valley and the desert. I’m here to help even if I’m not the right fit — if selling somewhere else makes more sense for your situation, I’ll tell you straight and point you in the right direction. → See our San Bernardino County service area
Failed Smog in San Diego County
San Diego County is mostly Enhanced, so most folks I talk to down here are in the same strict tier as OC and LA.
That said, San Diego does have some areas where the criteria vary by where you live, so checking your specific ZIP on the state’s locator before you commit to a repair quote is just smart.
What I see a lot from San Diego customers is the cost stacking — the diagnostic charges, the STAR station re-test, the shop labor — all piling up on a car that maybe wasn’t worth much to begin with.
So instead of chasing the certificate, a lot of people just call me. I come down from Orange County the same day — whether you’re in Oceanside, Escondido, Chula Vista, or right in the city — and I handle the title transfer paperwork myself. → See our San Diego County service area
Failed Smog in Ventura County
Ventura is also an Enhanced Smog Check area, and on top of that it’s on the state’s list of counties where a smog inspection is required at registration renewal.
So a failed smog test up here doesn’t just sit there — it stops you from renewing your tags, which then turns into a whole separate problem if your registration starts lapsing.
It’s a smaller county than LA, but the STAR station rules still apply if your car gets flagged as a gross polluter. And Ventura just doesn’t have the density of shops that OC and LA do, so the runaround can actually be more frustrating up here, not less.
I come to Oxnard, Thousand Oaks, Simi Valley, Camarillo, Ventura, and everywhere in between. One phone call, fair cash offer, paperwork handled. → See our Ventura County service area
Frequently Asked Questions
Can I legally sell a car that failed the smog test in California?
Yes, but there are rules. If you’re selling private party, the vehicle must first be placed on Planned Non-Operation (PNO) with the DMV. This tells the state the car is not being driven on public roads. In addition, you need to make sure the title is fully transferred out of your name at a DMV, AAA, or registration service office. On the other hand, if you sell to us at goCarBuyer, we handle all of that for you — no PNO required on your end.
How much is my car worth if it failed the smog test?
It depends on the year, make, model, mileage, and overall condition. For example, a junkyard will typically only offer scrap value regardless of how well the car runs. Meanwhile, the state CAP program pays $1,350, $1,500, or $2,000 depending on your income. Private party can get you more, but it takes time and effort. When you sell to us, however, we give you a fair cash offer based on the actual value of your vehicle — not just the weight of the metal.
Do I need to fix my car before selling it?
No. You do not need to fix anything before selling. For example, if the repair is cheap — like a $15 gas cap — then it might be worth doing so you can pass the smog test and sell at full value. But if you’re looking at hundreds or thousands of dollars in repairs, it usually makes more sense to sell the car as-is and let someone else deal with it.
Will Carvana, AutoNation, or Driveway buy my car if it failed the smog test?
No. Companies like Carvana, AutoNation, and Driveway want clean, retail-ready vehicles they can put right on their lot or website. If your car has a Check Engine Light or failed the smog test, they’re not gonna buy it. That’s one of the main reasons we started goCarBuyer — to help people in Southern California who need to sell a vehicle that can’t pass smog.
What is the California Consumer Assistance Program (CAP)?
CAP is a state-run vehicle retirement program through the Bureau of Automotive Repair. If your car failed the smog test and meets their eligibility requirements, the state will pay you $1,350, $1,500, or $2,000 to retire the vehicle, depending on your income. Keep in mind, though, your registration can’t have lapsed more than 120 days, the car must start and drive on its own, and the process can take 6 to 8 weeks or longer to get paid.
What if my car doesn’t run — can I still sell it?
Yes, absolutely. A junkyard will buy non-running vehicles for scrap value. Similarly, we buy non-running vehicles too. We’ll come to your location, pick it up, handle the paperwork, and pay you cash. The CAP state program, however, requires the vehicle to start and drive under its own power — so that option would not work for a non-running car.
How fast can I get paid if I sell to goCarBuyer?
Same day. Once we agree on a price, we come to you — your home, office, storage, wherever works — and we handle everything on the spot. As a result, you walk away with cash in hand. No waiting weeks for a state check, no hoping a Craigslist buyer shows up.
