Nissan Juke limited to 40mph, suspected limp mode after sudden speed drop on Nissan Juke

Some Nissan Juke owners report experiencing sudden speed drops and being limited to 40mph, which may indicate the vehicle has entered limp mode. This protective feature activates when the CVT transmission detects slipping, aiming to prevent further damage to internal components. Owners note that regular maintenance, such as changing the CVT fluid every 30,000 miles, can help reduce the likelihood of encountering limp mode. When this occurs, it is recommended to safely pull over and attempt to reset the computer after stopping the vehicle. Additionally, some owners have found that limp mode can be triggered by less common issues, such as a bad tank of gas or water on the MAF sensor, alongside specific diagnostic trouble codes like P0102, which indicates a potential MAF sensor issue. It is advisable for owners to have their Nissan Juke inspected by a qualified mechanic if they suspect limp mode due to a sudden speed drop.
