Inappropriate New Terms After The Purchase

Beware of “special order” You won’t know it’s a “special order” until GMPartsGiant.com charges your card, then sends you an email 2-3 days later, saying you must agree to “new terms” before the item will ship. “New terms”, “special order” equals “non-returnable”. As a consumer I should have been made aware of that prior to the purchase, giving me the option to use another vendor. Not only was that inappropriate, it delayed the completion of a customer’s vehicle. Don’t get mislead by an item that is listed available or in stock. I strongly suggest if you use GMPartsGiant.com, you call to verify the status of the part.

Con Artist

Con Artist, they will find any way to get additional money from you after your purchase. You pay for shipping, but when it come times to ship your item out they will hold it hostage until you pay an additional shipping fee. Then your product arrives damage because they won't package large items, they will just zip tie a shipping label to the part is send it out. After the part arrives damage due to lack of packaging they refuse to correct the issue and request a 20% restocking fee during the return process. Stay away unless you like to give your hard earn money away. Pay the extra cost and get your part from somewhere else, it will be cheaper in the end to get straight from the dealer at this point.

You order parts from them and pay the price advertised online. Then you get an email asking for more money. Total scam business.

They refused return even though part didn't match their picture of it

I ordered a shift cable, relying on the picture in the part listing. Although it bore the correct part number, the cable I received did not match their picture of it, which I didn't notice until I opened the package. Their return policy prohibits returns of items when the package has been opened. Even under these circumstances, they refused to authorize a return.

Bait & Switch - Be prepared for price increase request after ordering

I placed on order on 10/4/25 for an AC condenser priced at $174 + $30 shipping. Two days later on 10/6/2025 I get an email telling me that the item price has increased by $45 and that my order won't ship unless I submit an additional payment. Automated message says that their website takes 3 days to update and latest prices aren't always reflected despite still allowing orders at listed price.
What kind of reputable business wouldn't honor a price that was already "locked in" by a customer order, given it was the fault of their own outdated database system? I can't recall ever being asked for more money after an order.
Needless to say I canceled my order and went to a reputable parts vendor instead of these jokers. STAY AWAY!!!

Good prices. Lousy return policy.

The company has prices much lower than my local dealer on parts I can't find on Amazon for genuine GM products - that's good. Just be aware of their restrictive return policy (its a long list of 18 reasons/categories ineligible for return) .... I didn't read it first and that's on me. In bold letters, they say "Electrical parts are non-returnable, regardless of reason or circumstance." In a day with more choices, I can find a company with similar pricing but boasting a more consumer friendly return policy. Unlikely to ever buy from them again.

No packaging and appeared to be a used part.

The items were high priced, but the accessory belt wasn't even in a package, and it looks used. I didn't know you sold used parts, but apparently you do.
