Why does my BMW i5 lose power at high altitudes?

I recently took my BMW i5 on a mountain trip and noticed that it struggled to maintain its power at high altitudes. What could be causing this issue and how can I fix it?

Hi Emily, high altitude can affect the performance of any car, not just the BMW i5. This is because at higher altitudes, the air is thinner, meaning there is less oxygen for the engine to combust and produce power. To fix this issue, you can consider getting a performance tune-up for your car or installing a cold air intake to increase oxygen flow to the engine.

Hey Emily, another factor that could be causing your BMW i5 to lose power at high altitudes could be the change in temperature. As you go higher in elevation, the temperature drops significantly, which can affect the performance of your engine and other components. To prevent this, make sure to let your car warm up before driving and consider using high-quality synthetic oil to protect your engine in colder temperatures.

Hi Emily, it's completely normal for cars to lose power at high altitudes due to reduced air density. However, if you notice a significant decrease in power, it could be a sign of a faulty oxygen sensor. I recommend getting your car checked by a mechanic to ensure all sensors are working properly.
