What owners say

Sentiment is sharply divided and heavily dependent on the specific generation, engine, and maintenance history. The older E87 generation (2005-2011) is viewed with significant caution due to recurrent electrical gremlins, high oil consumption in certain engine

• High and unpredictable maintenance/repair costs: very frequent.
• Oil consumption issues: recurrent (specifically mentioned on a 2018 118i requiring weekly top-ups despite a recent timing chain replacement).
• Electrical faults and gremlins: recurrent (flickering electronics, steering column lock failures, melted battery terminals in E87).
