Used GMC trucks for sale near Oceanside, CA

My service writer, Sara, was excellent! She was kind, communicative and made sure I was well taken care of. I highly recommend the Carlsbad Jeep location when in need of servicing your car.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

What an amazing experience! I had the pleasure to have John Khalil as my sales agent, who happens to not only be a welcoming and zealous sales agent at CarMax of Oceanside, CA, but also a very talented painting artist!! He had great compassion for my autistic son and made sure he was always comfortable during the efficient waiting process by offering him a cute CarMax car toy, a CarMax coloring book and crayons. He went above and beyond when complex situations came about during the bank’s verification process. The determination he had to push my situation through with his persistent diligence as I watched him communicate with high professionalism and positivity as a team with his colleagues/finance management team was remarkable!!!! Thank you, CarMax of Oceanside, CA!! You all are an amazing TEAM!! I’m so happy with my car!!!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Emailed through Cars.com on a specific Ford Fusion Energi. Austin Webb responded in a few minutes and made arrangements to go see the car. Easy, no pressure, very friendly. We made a deal and I drove home in the Fusion. The dealer is very small - unlike many other dealers I have been to. They are friendly, efficient and no games. Highly recommend Encinitas Ford. I will be back there buying again in the future for sure.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

I asked for the detail to polish out few scratches and scuffs, the car was taken back to the detail shop and brought back with little to no change. Either the detail shop did a poor job or nothing at all. While the salesperson was very nice and attentive, he mentioned that even new cars have scratches on them. .y concern was my car not the new cars.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Very communicative and help helpful through the buying process. Offer the best prices definitely recommend.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

My husband Paul and I recently purchased a '06 Saturn ION from CarMax in Kearney Mesa. We were greeted with friendly and professional service. The purchase went smoothly and we are happy with our Saturn Ion.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

I had the car I wanted transferred in and from start to end they kept me informed. The waiting period was a bit of a bummer, but knowing that my car was arriving made it worth the wait. Ryan was super he completed the transaction and put us in good hands. We had a minor defect with the windows but Ryan made sure it was taken care of . Overall we were quite pleased. We're definitely getting a second car with them . Lidia

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I was assisted by Reef and Parker, both were extremely helpful and attentive and never made me feel rushed or stressed to make a decision. When the car I intended to buy was sold just hours before I returned to the dealership, Parker helped me find an even better vehicle. I now own a 2026 Hyundai Santa Fe Calligraphy Hybrid and it has been amazing! I would highly recommend the vehicle, the dealership, and the salesmen.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I bought a Dodge Charger R/T here. I just want to say that I had excellent treatment. Professional, courteous, and welcoming!

I bought my gmc sierra in 2009 , brand new, and it’s the best truck that I have ever owned, and I have tried a lot of nice trucks, I mean i have owned a truck, Ford used to be my favorite , but it doesn’t even stand a chance up next to a gmc sierra like mine, my brother in-laws were very jealous about me owning it, my brothers all liked it, I have had a lot of pleasure driving my truck, and I have had very little problems with it, I’m retired now or i would buy another one just like it, gmc is the premier truck, it’s the very best, i love my truck.

Good, experience. Alex is very helpful, goes over what's needed or recommended. Makes sure your comfortable while waiting.

The customer services was amazing through the whole process. Everyone from finance to the sales team were helpful and easy to work with. I love my new Jeep Cherokee.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Vanessa is a super service rep at Kearny Mesa Kia Service Center. She is really helpful and very knowledgeable. I look forward to working with her again on my next visit.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

The response time was really fast, I had received an email back within an hour. I was actually surprised how quick they had contacted me about my inquiry and I would recommend them to a friend

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

No complaints, all praise and compliments! I admire carmax business model, and them having a no negotiation rule is a beautiful thing. Ray was my consultant and we sold our 2012 forte to buy an suv. Message me if you have any questions and I will answer them.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

My car issues have been resolved . The price was dropped down, I did wish they would of payed for the whole deal, but it is, what it is. The word integrity has been lost in today's world.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Excellent overall experience. Sales representative was not the most knowledgeable, but was very attentive. The facility was clean and sales did not apply pressure. Representative made several follow-up calls which were appropriate and helpful to my search.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

No pressure to purchase. The vehicle appears to be in great condition. Sales person very knowledgeable

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

This truck is great if your not trying to haul 10k lbs. For every day use it's great on gas and I fit everything I need in the bed.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !
