   Audi A4 Water pump and Thermostat failure. VW/ Audi USA had a recall on this issue for several models including the Audi A4 models thru 2016. My car was built in 2016 with model year 2017 and according to the recall my car did not qualify. Since then there has been several Class Action Lawsuits for this same issue. I was fortunate I discovered the leak while the car was parked in my garage and wasn't on the freeway. It seems that VW/Audi USA hasn't corrected this issue…

   Every time I start the car, a message comes on saying that the passenger airbag is off even when I have an occupant next to me. I spoke with the dealer and he told me that this recall was claimed and fixed in 2022 in Texas by the previous owner but I replied that the problem continues and he told me that this was no longer an Audi problem. Furthermore, every time it accelerates over 40 miles per hour, a message about the driving system in malfunction appears and also the…

The car was left in the following condition: Engine off. Gear indicator showing "D". Accelerator pedal unresponsive.…

   2017 A4 B9 premium plus model, AWD, 2.0T. I have had an Audi dealership service my car for all major service intervals outside of oil change, not only at recommended intervals but even early. 3 years ago I had my 40K mile service done at 35K miles. Spark plugs were replaced by Audi Hawthorne in Westchester county, NY. One week ago, at 49K miles (well before the 6 years or 60K miles Audi says their spark plugs will last) my engine seized while driving and was misfiring. This…

   Start Stop system failures. Upon engine restarting, it stalls instead. This has happened on multiple occasions and the dealer response is to just turn it off every time you start the car. Causes dangerous situations due to inability to move car until full power cycle happens.

    Engine light on Dealership found a rodent nest in the engine space in the car. Dealership considers that fluids used to coat Audi engine wiring attract rodents. Dealership considers this to be a health and safety issue. Dealership considers it essential to replace the Audi air filter. Dealership is checking wires to assess any gnawed damage. I need the engine to be power-washed and the nest area treated w/bleaching agents. I do not have the total estimate on this but it will…
