Summary Verdict

The 2007 Audi Q7, particularly with the V8 engine, can be prone to significant repair costs related to its timing chain system and oil consumption. The adaptive air suspension is another area that may require costly repairs due to leaks or compressor issues. While the V6 engine generally presents fewer major concerns, issues like PCV valve and ignition coil failures are not uncommon. Transmission problems can also arise, leading to expensive repairs. Electrical gremlins, especially with the MMI system, and interior climate control issues are also reported. Prospective buyers should be aware of these potential reliability concerns and factor in the possibility of higher-than-average maintenance and repair expenses.
