Ellie K. - JRodela06

Ellie K. helped me through the purchase process when I found the perfect Escalade for my mom. She sent pictures because the website had not been updated, I drove over an hour to check out the Cadillac. Went over numbers and trade, the following week my mom had her well deserved Escalade Platinum. Some issues arose on the way home and Ellie scheduled me in right away with a loaner to check out the warnings. Some things could have been better since there were immediate issues(l understand buying a used vehicle), but overall a positive experience during the purchase process.

2015 CADILLAC SRX CERTIFIED - Joe

DO NOT RECOMMEND THIS DEALERSHIP TO ANYONE. Purchased a certified vehicle from the 1 month later paint is coming off of it and the dealership will not help us. Poor customer service and overall experience was garbage.

I was in the market for a Hummer EV and test drove one at - etienneannaert

I was in the market for a Hummer EV and test drove one at Thorson, I've also brought my Hummer EV in for warranty repairs (hasnt been 400 miles yet). I had worked with a broker who had found me a Hummer EV deal in San Jose, and came to Thorson to test drive one. They had one I liked, and showed the Jose one of the sales reps the deal I had and said if they can match I'll get theirs instead. Took them almost two weeks to get back to me, but by that time I had already had one delivered to me. Fast forward 25 miles in- my hummer has an horrible dashboard rattle, a loose rear view mirror, quality issues with the dome light and trunk headliner, and a trunk that won't latch closed properly. Took it in with a reservation, I think the service reps name was Lola - no loaner provided. Picked up hummer a few days later, and they had only fixed the mirror and attributed the rattle to a loose tool in the back. Took it back two weeks later, because the trunk still wasn't fixed and it had a rattle. Got it back couple days later, trunk still isn't fixed and rattle wasn't even addressed. Now I'll be dropping car off again tomorrow. Really trying with this place, but not very professional to leave issues unaddressed (literally no line items written down for at least duplicating concerns or unable to duplicate concerns - just blank).

I recently had one of the most frustrating dealership - Jon

I recently had one of the most frustrating dealership experiences I have ever encountered while trying to purchase a used 2025 GMC Sierra EV from Thorson Pasadena GMC. After seeing the truck listed on their website, I immediately called on a Friday and spoke with Walter. I explained my situation, my interest level, and my trade in details for my 2018 Ford Raptor. Walter had me complete the appraisal forms and gave me an acceptable offer on the trade in and assured me that he would make the truck available for me to buy on Monday. Because I live more than an hour away and had family commitments over the weekend, I could not come in sooner, and he acknowledged and agreed to hold the vehicle by placing it in service status. Monday morning, we confirmed my arrival time by text. Everything seemed squared away. After driving nearly an hour, I was two minutes away when I received a call from Chris informing me that the truck had just been sold. I still went inside the dealership to speak with the sales manager. Instead of any meaningful explanation or accountability, I got a simple shrug and a reminder that they “do not hold cars,” completely ignoring the fact that their team had already agreed to do exactly that. No real apology, no remorse, no ownership, just indifference. Chris and another associate, Jonathan, did offer to try to locate a similar truck at auction and deliver it to my home for inspection, which at the time felt like a decent attempt to make things right. Unfortunately, that promise turned into nothing as well. I never received a follow up call, not a single update, and no apology from anyone at the dealership. I was essentially ghosted after being told they would help correct the situation. I had gone out of my way to prepare my trade in, rearranged my schedule, and drove a long distance based entirely on their word. The lack of communication, broken commitments, and complete disregard for a customer’s time was incredibly disappointing. Thankfully, I found the same model Sierra EV at Culver City Chevy, where I was treated with professionalism and respect from start to finish. I would strongly caution anyone considering working with Thornton Pasadena GMC. My experience showed poor communication, poor internal coordination, and a willingness to make commitments they do not honor.

Purchased a Hummer EV from this dealer, not even 1k miles - Smarterpads

Purchased a Hummer EV from this dealer, not even 1k miles in and I’ve brought it in 3 times to both Thompson and Casa. At Casa, I’ve never been treated so poorly by a dealership. Lira Angel, stay away from her and her condescending tone. Doesn’t know the different between a software update and a reset and the need to run a hardware check as advised by corporate. Kept the car for 3 weeks only to replace parts on the car that were already replaced and did not need replacing.
