If you are buying through the Costco Auto Program, stay far away from Keyes Hyundai of Mission Hills. When buying our vehicle, the dealership forced a $2,290.00 charge labeled as "Required Dealer-Installed Items" on their Costco price sheet, which they bundled entirely onto a KARR Security System warranty contract. When we had to switch to a dealer-traded vehicle to get our preferred color, the physical KARR alarm was never installed on the car we took home. Charging and financing over $2,000 on an auto loan for physical hardware that was never delivered is bad enough, but their response when we tried to address it was even worse: 1. Complete silence and stonewalling: When we first discovered the issue and reached out to cancel, the finance department completely ignored our emails and never returned our phone calls or voicemails. It wasn't until I showed up at the dealership in person with a formal demand letter that anyone would even acknowledge the situation. 2. They admitted in writing it was never installed: Once management finally responded, General Sales Manager Jason Jhee sent an email encouraging us to have KARR come install the system after the fact if it wasn't done already. 3. They falsely claimed Costco mandates forced add-ons: In that same email, the GSM claimed that "the added items are mandatory. It states that on our agreement with Costco"--blatantly contradicting the contract's own disclosure stating the product is optional, as well as California add-on rules. 4. They refused our refund and offered oil changes: When we pointed out the non-delivery, the GSM reversed course, claimed nobody forced it on us, insisted there is "no 30-day cancellation window on a non-cancellable product," and dismissed a $2,290 charge by offering four complimentary oil changes. Billing customers for uninstalled equipment, disguising optional accessories as mandatory, ignoring customer communication, and brushing off legitimate cancellation requests is completely unacceptable. Take your business to an honest dealership that actually delivers what they finance and respects partner program terms.

​Extremely disappointed with Mission Hills Kia/Hyundai. Took my Santa Fe in with code P0304, a documented TSB (technical service bulletin) issue that causes severe engine shaking and sudden, dangerous stalling. They charged me for a diagnostic and oil change, promising to contact my warranty company once I handed over my policy info. I provided everything the next day, and now they completely ignore my calls and messages. Taking customer money, ignoring a known safety defect, and dodging phone calls is beyond unprofessional

The sales person who assisted me, Kiwi Jay, great guy, very honest, helpful and patient. I recommend him and same with Donna Parker.

Dealing with sales staff was always a stressful point for me when car shopping. Besides having a competitive price from local dealers, Mr. Jay Mika made the whole experience excellent for me as I found them online. I was pleased with the whole process and will look at their inventory first for future vehicles!

Rob was very kind, and his patience and understanding of my needs were invaluable in helping me make my decision. He took time to explain, not just the car's fancy features but how such features could be utilized. He answered all my questions without frustration or judgement. He was energetic and helpful.

Confusing CPO Pricing and Poor Explanation of What We Were Actually Buying I bought a certified 2024 Hyundai IONIQ 5 here, and while I ultimately liked the vehicle, the sales process was extremely frustrating. The main issue was how the CPO pricing was presented. The $1,000 discount was what drew us into the deal. Art repeatedly confirmed that the vehicle was already certified, but later explained that taking the $1,000 discount meant removing the CPO benefits. We were then quoted around $2,100 to restore CPO, before ultimately being offered CPO again for about $1,000. By the end, we were essentially back at the original advertised deal, so the discount that attracted us had disappeared. What made this especially frustrating was that the warranty comparison was not explained clearly. We were repeatedly told about Hyundai Select having only a 90-day/5,000-mile powertrain warranty, but it was not clearly explained that this low-mileage 2024 vehicle would still retain the remainder of Hyundai’s transferable 5-year/60,000-mile factory warranty even without CPO, along with substantial separate EV warranty coverage. That information was very relevant to deciding whether paying extra for CPO made sense. Art also gave us confusing or incorrect information about Bluelink and the benefits associated with the certified vehicle, while simultaneously trying to sell an additional security package. Donna in finance was pleasant, but I also discovered afterward that our paperwork says we received the completed certified-used-vehicle inspection report, while I could not find that report anywhere in the digital documents we were given. I had to contact the dealership afterward to request the CPO inspection paperwork and warranty documentation. I became frustrated at the end and wanted to switch to the Select offering with the $1,000 discount, because that was when the pricing structure finally started to make sense to me. It probably looked like I was suddenly changing my mind, but I had only just realized that the original $1,000 discount had effectively disappeared. I would strongly recommend that anyone buying a certified vehicle here ask for a written breakdown of exactly what changes when a discount is offered, what factory warranty remains regardless of CPO status, and copies of all CPO inspection and warranty documents before signing. The car itself may be great, but the sales and paperwork process should have been much clearer.
