Sierra Chevrolet of Monrovia

Service dept. My advisor was Abraham, he did an excellent job communicating and following thru on what he said. Had an issue with the convertible top. I have extended warranty and Abraham took care of everything with my insurance. I just had to pay my deductible which i expected. They returned my camaro back in 2 days and everything was smooth. Compare Sierra to puente hills Chevrolet,,puente hills was a nightmare lol. Thank you to Abraham and Tanya. I appreciate your service, any future issues with my camaro, I'll come see you again

I had an extremely disappointing and frustrating experience with Sierra Chevrolet of Monrovia. When we purchased our 2022 Chevy Bolt, they loaded the deal with unnecessary add-ons that increased the total price by about $15,000. One of those add-ons was a key fob warranty that supposedly covers replacements if anything goes wrong. Fast forward to now — our key fobs stopped locking the vehicle. I called ahead and was told to come in for a complimentary replacement since we had the warranty. But once I arrived, I was suddenly asked to sign paperwork agreeing to pay $310 for diagnostics just to look at the keys. That’s not what we were told on the phone, and it completely defeats the purpose of buying their warranty in the first place. This felt deceptive and unethical. Selling warranties and then refusing to honor them without additional fees is unacceptable. We walked out and took our car elsewhere. Do yourself a favor and avoid this dealership. They sell products they don’t stand behind, and their practices feel dishonest. I would not recommend doing business here.

Dropped my car off for service & I have mixed reviews. The employee I worked with was very attentive, great customer service. But before I dropped off my vehicle, my check engine light code was something that (online and a different technician verified it was still good under the warranty) was still under warranty. When they called me to inform me what the code was they told me I was looking at approximately $1,100. I informed them about the warranty and once they called me back they said GM would cover it, even though I was past the warranty. Cool no biggie. My issue when I got home was, I noticed an animal got inside my vehicle and ate a SEALED bag of popcorn inside my vehicle. There were tiny paw prints on my doors as the evidence. I’m assuming they left my windows down overnight or unattended.

Picked up a Mazda CX 70 2025 and got a really good deal! They even gave me paint protection for no cost without me asking. See Jon the sales manager over there. Really nice guy to work with. I had to keep on top of my sales guy Elliot haha, but he is young. They picked me up from my home in Orange County since I did not have a ride up there. Since I had my loan in place first, I always negotiate price first over the phone. These guys were the easiest people to work with and I felt at home with them. I highly recommend them.

My experience at Sierra Chevrolet was fantastic from start to finish! I recently purchased a 2025 Chevy Equinox EV and I couldn't be happier with the car and the service. I initially spoke with Alfonso and Will. Alfonso was incredibly knowledgeable – he explained the particulars of the car in detail. Will was the guy I worked with to finalize the price. I was on a tight budget and needed a quick turnaround, and he was incredibly understanding and patient. He answered all my questions honestly and honored my request in regards to lowering the price to what I think is the absolute minimum. The next day, Luis made the trade-in and purchase process seamless and quick – I was in and out in no time! I'm happy with my car so far and I had a great experience interacting with everyone. I highly recommend Sierra Chevrolet, and especially Alfonso, Will, and Luis, to anyone looking for a great car buying experience.
