    2023 jeep

    Loved this dealer just got a 2023 jeep thanks to Anthony Rubio with Monrovia CDJR gave us great customer service and very quick process!

    Super happy customer!
    Costin H.

    An absolute fast and seamless transaction. After inquiring on a 3500 Limited truck on the phone, we pulled in and the truck was already out and ready for a test drive. Guillermo, our sales rep was super nice, fantastic at explaining the car and features which are very sophisticated on a 3500 no sales push ever. Edwin the sales manager made the numbers work in less than 15 minutes and we were amazed by the deal we got and Ed the finance guy was the cherry on the cake, super smart, very good at explaining numbers and we were out in no time. I never thought a truck transaction can go so well, where you are super happy with the price, customer service and finance. These guys deserve our/your business.

    Proof of them not answering & not responding to any of my messages for hours at a time very unprofessional.

    I've had a very frustrating time getting a hold of the service department, every time I call they never answer even when leaving a messages they take hours at a time to even get back to me. Very unprofessional they said my truck was gonna be done with in the first week of it being there & now it's been almost a month & they still have my truck waiting for a part that was supposed to be an overnight delivery part.

    Text messages between myself and the dealership.

    First I'll say I do not take one star reviews lightly as any business deserves a fair shake before being dragged online. That said, this dealership, specifically their service department, is dishonest and disingenuous while being absurdly priced. I brought my 2019 RAM 2500 Limited with the 6.7 Cummins in due to a check engine light. I have an OBD tester at home and went in with the specific error code and stated the particulate sensor needed to be replaced. I asked the technician what the cost would be to replace it and he said he did not know but wouldn't think it's very expensive. While I knew there was a fee for them to take a look at it, the service tech stated the fee would go towards the sensor replacement if I moved ahead with the repair. Well the following day, he texted me stating the particulate sensor needed to be replaced. No surprise there since that is what I told him when I dropped my truck off. He then quoted me a price of $714!! When I pressed him for why in the world was it that expensive the breakdown he gave me was $240 for the part (which is $120 online), $240 for diagnostic fee (which he told me would be waived if I did the repair), $240 for labor, and approx $25 for taxes. See text messages below. Not only did this guy lie about waiving the diagnostic fee, this dealership is completely and disgustingly, ripping people off on a repair that takes less than an hour. I picked up my truck, they had the audacity to charge me $240 despite me telling them what the issue was when I dropped it off AND showing the error code to them AND eluding to any replacement not being very expensive. There was no offer to waive the payment. And when I politely asked to talk to a technician about replacing the sensor myself, they just told me that wasn't possible. I've been taking my truck to this place for maintenance and repair work for years but will never return. I know that post covid service in general has seriously degraded but there's simply no excuse for ripping people off the way this dealership does. Honestly, stay away. Give your time and hard earned money to a business that appreciates repeat customers and doesn't exact pleasure from ripping them off.

    My Jeep was loosing coolant at no apparent location, so I needed service. The girl that answers the phone is one grouchy woman. Think her name is Hay Sue or something like that. Really in a bad mood and very sarcastic. I should have stopped right there. But no, I took my jeep in for service. They had it for 1 week and when I called, they had not even touched it. Wow, I been renting a car this whole time for nothing! While they were finally looking at my Jeep, they called me say they don't want to work on it as long as I have a dash camera on. LOL! I told them unplug it then! It like the workers have warrants or something! When I called the "service advisor", he did not respond to my calls or text messages. The next day, he said he had the day off. WTF! Like couldn't another person take over while he was off? Finally had to ask for management. Manager took over my service. After more days, he says they checked the engine with a scope and did block test and everything, and couldn't find anything wrong with my Jeep and sent me on my way. I went to my local mechanic, he squeezed one hose and said too much pressure, head casket needs replacement. He changed it, and changed anything else that he was disassembling along the way to avoid problems later. My Jeep was fixed by my local mechanic. I will NEVER go to a dealership for repairs that are out or pocket for the rest of my life, especially Monrovia Chrysler Dodge, Jeep dealership! They are rude, incompetent and over priced! To boot, the dealership kept my engine cover! Ugh!

    Mounting bolt broken off.

    Very unhappy. -I brought my camper van in for a repair. There are two sets of keys in the van for locked compartments inside the van. When I picked up the van, both sets of keys were obviously tampered with, as they were both not in their normal spot. These keys and compartments had absolutely nothing to do with the repair of an alternator. -There was at least one bolt that was broken off and not replaced, just left broken off. Now that component is not secured as it should be. -When I picked up the van it was taking quite a while for them to bring the van to the front. Finally they told me that they closed the hood and now they can't get it open. They took me back to the service area and there were 8 people working on trying to get the hood open. After a great deal of paint being chipped off of the lip of the hood, they were able to open it and correct the mistake. It was explained to me that they forgot to strap a cable and when they closed the hood it got stuck in the latch. This does NOT give me confidence that the other repairs that I can't see were done properly. -The final repair costs were almost twice what I had anticipated. (About $3600). Possibly my fault for not being more diligent with adding up the repairs, plus tax, etc.. To add insult to injury, they charged me an extra 3% of the total bill because I paid using a credit card. The service department representatives were friendly and helpful, but the technicians can not be trusted in my experience. I will not be returning to the dealer for future service/repairs. -On a positive note, the new alternator seems to be working fine.

    Best Dealership, Their Price are reasonable, and Best sales person Gillermo  Hernandez

    I am interested in a Jeep Wrangler 4 door on your lot, and would like to know whether you charge a market adjustment fee on top of MSRP?

    Yes, most definitely they have markups which vary depending on the vehicle.

So the filter cost more because my car is 2021? Theres fees I've had to pay more than what Groupon shows so just a heads up , not their fault, but just something they should fix. An example would be like "more oil is required then what shows on Groupon so you will be charged 8$" or something always comes up when using the groupon. Ended up paying 20$ more than what groupon showed to fill my lexus and get the proper filter. So the service was like 100$ total anyways. Ive come here twice and both times were unpleasant. Not sure if I come during bad times but although very friendly, it seems like the workers here are younger , more relaxed, and don't do the proper standard operating procedures. Like when you go to have someone work om your car , you can tell they been working, getting it , and seem to make u feel like they know what theyre doing. In terms of professionals? Idk if this place is it. I waited 1hr and 45 mins for a simple oil change and filter change? Mind you I waited for an hour and the worker tells me they brought the wrong filter. So thats why i stayed the extra 45 minutes. Total i spent 1hr and 45 minutes there today. I was also the only car there. I never judge a book by its cover , and on both times gave the benefit of the doubt. Then I leave and then see they forget to reset the maintenance meter and then don't update the gas mileage sticker? (first instance i came not the second, the second is the long wait thus what caused this review) Its frustrating when you trust people to work on your car and have to just hope for the best because you already paid for it. But if they're messing up minor details, what does that say about the work they did? Nevertheless, I will pay the extra 40$-50$ at my local auto repair shop where the owner does his work honest and right all the time. Im not writing this to bash the place but they forsure just hiring whoever can do "a simple oil change" probably not a place you wanna take a newer car. Maybe your beater or older car. Just wrote this so people who come for an oil change and expect it to be quality.. yeah based off both experiences , I cannot guarantee its gonna be this place.

From the moment you pull up, they make the whole process feel easy and stress-free. One thing I really appreciate as a woman in my 20s is that they actually take the time to explain everything they're doing and walk you through the service without making you feel uncomfortable or pressured. Unfortunately, I know a lot of women my age feel nervous going to car service places alone because it can feel intimidating or like you're being taken advantage of. I never once felt that way here. They were honest, patient, and genuinely helpful. The customer service is honestly top tier. They even offer you a water while your car is being serviced, which is such a small thing but makes the experience feel that much more thoughtful. The fact that you stay in your car the whole time is also a huge plus. The service is quick, efficient, and the staff keeps the conversation going so the time flies by. I was able to get my oil changed and still have enough time to grab lunch all within my one-hour break from work. I came back to the office talking nonstop about how great my experience was.

When I checked the dipstick myself, the oil level appeared low and the oil was dark with a burnt smell. I returned the next day to speak with the manager (Luis), who insisted the oil had been changed and showed me what he said was a new oil filter installed by the technician (Torres). However, when I expressed concerns about the oil condition and asked if they could redo the service for customer peace of mind, I was told I would have to pay again. The original manager on duty during the service was Mike. What concerns me most is not just the oil itself, but the lack of transparency and unwillingness to address a customer's concern in a professional way. When basic steps like resetting the maintenance system are missed and the oil appears questionable, it's reasonable for a customer to ask for reassurance. Unfortunately, I did not leave feeling confident that the service was handled properly. Luis refused to redo the service free of charge and at this point I realized that it wasn't doing anything by going back and forth. I would recommend customers going somewhere else.

Daniel took the time to thoroughly inspect the vehicle and clearly explained what they found -- loose rear suspension hardware and a missing trailing arm nut that could have turned into a serious safety issue. What I appreciated most was Daniel's professionalism. He walked me through everything step by step, showed me exactly what was going on, and answered all my questions in detail. He was calm, knowledgeable, and transparent. He also stayed completely professional and never made negative comments about the original installer -- he simply focused on fixing the issue and making sure my vehicle was safe. They properly re-torqued and secured all the suspension components and performed a full alignment to ensure everything was dialed in. The truck now drives perfectly -- stable, smooth, no more clunking or sway. On top of that, their pricing was very fair and reasonable, especially considering the safety issue they corrected. It's hard to find a shop that combines honesty, skill, and fair pricing like this.
