GMPartsGiant.com Avis 

The parts arrived as predicted. There was no issue with packaging. Parts were installed and are working well.

Easy to find and order. Good price and delivery as scheduled.

You guys and girls had hard to find parts at a cheap price fast shipping. Once the process went through the processing took a minute other than that wonderful as well as I could not find these parts anywhere else except for use 2013 Cadillac ATS Luxuria edition.

Parts were of great quality

Parts were easy to find on site. Prices were good. Delivery was timely.

Easy to navigate the website, had the part I needed, got it to me intact and quickly all at a competitive price. What more can anyone ask for?

The part I needed was reasonably priced. The order process was easy, with no surprise shipping charges. My part wa delivered when they said it would arrive. I was replacing a failed USB/USB C/SD card slot that I use for Apple CarPlay. The part was easy for me to install and Apple CarPlay is working great.

Great part. Cheap price.

Everything was as expected.

Great price, product and shipping. No issues, easy transaction.

Prices as good as cheap aftermarket on Amazon. Why buy junk when you can buy the real deal?

Worst experience ever I bought paid 150 to have installed within a week it had already quit working I called and idiots wouldn’t do anything about it I’ll never use this company again and I’ll warn everyone else not to

Quick delivery. Best price.

I ordered a part and paid only to find out days later as I was waiting on the part to arrive , so I could fix my car and drive it, that my order had been automatically cancelled because GM parts giant did not actually have the part they took my order for. This is why every business takes inventory. Loss of trust. Using GMpartsgiant left my vehicle sitting an extra 3 days, only to be fixed by a competitor.

RUN. Just look at the other bad reviews and GMPG’s robot/ gaslighting responses.

I had to order a pack of 10 o-rings because they wouldn’t sell just one, which felt understandable at the time because I couldn’t find the part elsewhere. Only two shipping options, so I spent over $8 shipping for a $13.50 part. Overnight shipping was truly outrageously priced at something like $60-80+.

The package got lost in Ohio for about 15 days (there was tracking on the package that just went silent). Customer service said they would issue a refund/replacement, and asked me to contact them to return the parts if they showed up. I agreed.

Then I got another message saying they would refund me if/when I returned the (still confirmed as missing) parts. Not what was said before, but ok… no more mention of a replacement option. After that it was radio silence, no refund and no part.

So much time elapsed that I had to research and order the missing part from a different company so I could just fix and drive my car: a single o-ring that arrived at my house within two days and worked perfectly for a fraction of the price.

The missing parts were finally found in the ether and showed up at my house almost 3 weeks after I ordered them. I had already fixed my car at this point, no thanks to them.

I let them know so I could send the parts back and get my money back per our communications. They quickly responded saying I didn’t spend enough money to get a refund according to their “policy”… I guess $22.14 is pocket change (in this economy?!). I have no use for 10 o-rings, but I could certainly use the gas money as a broke college student. Gonna donate them to a community reuse center so this isn’t a complete wash I guess.

This has been one of the absolute worst customer service experiences I have ever had. They have zero accountability to their customers, or care. They are incredibly dismissive and flippant once they have your money. Their attitude felt very much “sucks to suck, it’s your fault for buying stuff from us.” I would recommend spending your hard earned cash at a place where they actually see value in their customers as people, not just money bags.

UPDATE: They called me the day after I posted this review, but chose not to leave a message. No way to know if it is correlated, but there was only one view on my review & I had never talked with them on the phone before, only via email. The fact they chose not to leave a message or send some sort of follow up email explaining what they wanted feels incredibly uncomfortable and intimidating. BLOCKED. $22 isn’t worth dealing with these people any further.
