The car had over a hundred thousand kilometers on it. The day after picking it up, the tire burst without us even driving it (from a previously patched area that exploded). The parking brake got stuck, making it undrivable. We reported the issue before 10 AM and contacted the rental company asking for a replacement because we had over 1000 kilometers left on our trip and didn't feel safe driving it. However, they only arranged for roadside assistance without providing a replacement car. The assistance arrived at 1:30 PM and replaced the tire with a spare, then manually fixed the stuck brake. I followed the mechanic to the service center for further repairs. Even after being informed of the car's safety issues by the roadside assistance, the rental company still hesitated to consider replacing the car. I contacted the rental company customer service again, but they reiterated that only repairs could be done, no replacement. The information was completely unsynchronized. I had to chase after the help center repeatedly. This location is really unreliable. I was worried this would delay my trip to Pattaya in the afternoon. They only mentioned repairs, not replacement, all under the scorching 36-degree heat. We didn’t get the replacement car until nearly 4 PM. The person who came to swap the car casually apologized for being late, which felt intentional because they clearly had available cars. We were three females, and one of my friends was so frustrated that she cried. After renting cars for so many years, Hertz really disappointed us this time.
