NHTSA Complaint #11638376 — 2012 AUDI Q7

On November 2, 2015, the Environmental Protection Agency and California Air Resources Board informed Volkswagen Group companies that my Model Year 2012 3.0L Turbo Diesel Injection (TDI) vehicle did not comply with Federal and California emissions standards. In the approved emissions modification, Audi Lynbrook claims to have removed the software that reduced the effectiveness of my TDI's emission control system and to have installed new emission control software designed to function effectively in all normal driving conditions. NOTE: this "fix" that was devised to meet emission standards was never actually tested for "vehicle reliability, durability, performance, drivability or other driving characteristics", and by their own account would consume 40% more DEF [XXX], meaning it's stressing the emissions system 40% more than designed. Since the TDI Modification my 2012 Audi Q7 TDI is having constant emissions system faults with 200 mile shutdown ransomware programming, and repeated replacement of the same components. It has rendered the vehicle as unreliable and now unusable unless I keep paying for Audi's "fix". My vehicle had no such issues prior to the TDI modification and received all regularly scheduled maintenance at Audi Lynbrook. I have compiled all my service records including the TDI Modification (7/26/18) then 9 emissions system failures (XXX). Currently, Audi Lynbrook states that again emissions component replacement is needed, a part (rear nox sensor G687) that was replaced 4/10/2023 just 20 months for the second time since 11/12/2020. This failure to deliver a reliably working vehicle has already cost me considerably, so Audi has disabled my car with shutdown programming, taken it hostage needing proprietary Audi service, and are now demanding ransom to make it temporarily usable.
