The only negative about the process was the shipping cost vs delivery time. The cost was steep for the amount of time it took to arrive.

Updated : One of the parts arrived broken

Update. My review and issue was actually with another site (also stars with GMParts…) and not with GMPartsGiant. I looked again after they reached out to offer me a refund. Well played on their part! They seem like a good company that cares about their reputation.

Original:
One of the parts arrived broken, but since it was an $8 part, the cost to arrange a replacement was higher cost to me than just buying a new one from someone who would pack it with a little more care.

Avoid this site

Advertised 1-3 days processing and shipping. Took 16 days for them to ship. No email or notification of delay. No compensation for complication. A poor attitude customer service representative and paid $65 for 3 week shipping of a plastic wheel well liner. Avoid if possible

Ordered 5w30 trans fluid and received 75w 80. They won’t accept returns for fluid, and they won’t refund me after stringing me along for 2 weeks. They even tried to act like these two viscosities are interchangeable and ultimately denied my claim. Do not use these people, they literally scammed me out of 70$ and I’m trying to get my money back through the bank now.

misleading site inventory and delayed my repairs week

My experience with GMPartsGiant was nothing short of aggravating. I placed an order for parts that were clearly listed as “in stock” on their website, only to have it canceled several days later due to “availability issues.” The site was never updated to reflect the shortage, which felt misleading.

When I tried to get answers, I was told to call — but their phone system simply redirected me without connecting to a real person. The online chat option was a joke, total waste of time leaving me with no direct way to resolve the problem. request supervisor multiple times, never granted even after multiple reps through chat.

Adding to the frustration, they kept a hold on my bank card for several days after canceling the order and refused to release it sooner. This tied up my funds unnecessarily and caused a major inconvenience.

Overall, the outdated inventory info, lack of communication, and slow handling of payments made this a very poor experience.

⭐ Rating: 1/5 – Misleading stock info, unreachable support, and delayed funds return 3 days

Fraud

3 April 2026 I went to gmpartsgiant.com website. You have to enter the vehicle prior to starting a purchase. I ordered a thermostat asm eng cool part 12642691 via sales order VG83642696. Part arrived 6 April 2026..April 24, I contacted to return the item because it was not the correct part for my vehicle. I was contacted stating it was an electrical part and not returnable. I informed them I had put the VIN in and this was the recommended part....they email back stating I received a superseding part 24588515 and the parts are interchangeable and should work. The website did not reflect the updated information and the final answer was still no I was not authorized a return....the part clearly was not interchangeable it was totally different..I had to go to the local Chevrolet dealer and get the correct part.

Hi Kimberly,

Thank you for your feedback.
After reviewing the order, we were unable to locate a VIN submitted at checkout. Fitment can vary without VIN verification, as multiple parts with the same name may apply depending on trim level or production date.

We recommend VIN lookup for the most accurate fitment before checkout to confirm compatibility. If a part that does not fit your application was ordered, and the correct part per invoiced was delivered, the return request will be categorized as a no-longer-need.

We understand your frustration; however, electric components are not eligible for no-longer-need returns.

We appreciate your understanding and encourage the use of VIN verification for future orders to help ensure exact fitment.
