I purchased a 2021 SX Telluride on Labor Day 2020. In May 2021 I began to experience break failure. I would depress the brake pedal to the floor and pumped it a few times to completely stop. I took to a dealer nearby and it was diagnosed as a foreign liquid in the system that contaminated the entire system. I agreed to have it all replaced. It took over 3 weeks for the vehicle to be repaired at a cost of $7K. I spoke with the shop that had done an oil change on 27 Apr 21 and asked if they had put in fluid into the brake system. They showed and explained to their process in doing oil changes. Their work tables had no fluids on or nearby. Their fluids are stored away from any work table and all bottles sealed. The shop rep mentioned that there would be no need to add fluids because it's a new vehicle. The shop also sent me the testing do they did for all fluids and the brake fluid test was fine. I have the photo of that test. This is when the shop rep went online and was able to locate that an exact issue as mine has already been reported. Website was Kia Telluride.org. The dealer service rep showed and gave a sample of the brake fluid and a photo of it as well. The first sample was clear with an oily a droplets in it. The second one is a different color. More yellowish. This yellowish color is the same color of what is in my telluride right now. So I don't what the dealer rep was looking at. I want Kia Corporation to pay for these expense since the issue already exist in two vehicles. and experienced the same thing. You may reach me at my email. The photo closest to the top of brake reservoir is what the dealer rep sent me. The others I took today 3 Jul 21. You notice the cap is off, tats because the dealer mechanic didn't cap the reservoir. Thank you for your time.
