I have a 2017 model Qashqai bought in 2019. This year, I went for the first inspection, but they said it couldn't be tested. Once on the line, the car couldn't be engaged; as soon as it hit 20, the speed dropped, but everything is normal when driving on the road, and there are no warning lights. Has anyone encountered a similar situation? Can you tell me the reason?

Jetur X70, 2020 model. I started having a coolant leak, and when pressure was applied, the leak point was found. The four-way valve was replaced, and the heating pipe and water inlet pipe were tightened. It was also discovered that the water pump was leaking, and eventually, everything was replaced. However, after refilling the coolant, the mechanic found that the engine temperature was high, but it drops as soon as the heater is turned on. They spent half a day but couldn't find the problem, and the car not being fixed has caused a lot of issues. Have you encountered this before? How did you handle it?

2021 Outlander Vehicle Odor Issue. Background: Recently, the car was parked in an underground garage for a month, and the garage was somewhat damp. Situation: An unpleasant odor, like a musty and rotten smell, has started to accumulate inside the car. Self-assessment: I've checked the interior but couldn't find the source of the smell. I also replaced the air conditioning filter, and the air blowing out doesn't have any odor. However, as soon as the car is parked for half a day and I get back in, there is a strong smell in the cabin. The car has never been submerged in water or flooded before. Question: Has anyone experienced a similar issue and can provide some guidance on how to deal with this?
