In early March, we rented a car from a Chinese company in Christchurch through Zuzuche. The car we rented was a 2005 Toyota hatchback. When we picked up the car, we noticed it was very old and the engine didn't sound right, but considering it was only a little over 100 RMB per day, we decided to rent it. From March 2nd evening when we picked up the car until March 10th, we drove it without major issues until we were heading to Lake Tekapo from Queenstown. Around 11 PM, while driving through a mountain, a high temperature warning suddenly appeared. We immediately stopped the car by the roadside. Since there was no mobile signal, we had to add water to the radiator. We added about 2-3 liters and the warning disappeared. However, after driving for 5 kilometers, the high temperature warning appeared again, and there was a persistent burning smell. We stopped by the roadside and flagged down passing vehicles for help. It was past 11 PM, and luckily a couple from Israel in an RV picked us up.
