What 38 owners told NHTSA about the 2013 Audi Q7

Lately, I have been adding coolant to my car - 2013 Audi Q& TDI and Motor Oil for unknown reasons why it was happening. It started last year, 2023. I thought it was a normal thing that the oil level and coolant level kept on getting depleted. Comparing with my other car, i.e. a 2016 Toyota Avalon, I never encountered these problems My Audi car was serviced sometime 2018 and apparently all gaskets of the engine were replaced after I complained about severe leaking of oil inside my car garage. Until I went online to get if there were similar complaints of other users of this car were reported. My friend's car of same Audi model was also experiencing the same issue. I was also observing a similar gas smell inside my Audi car, whenever I start the engine and my air vent is not closed for couple of months. When I had it serviced to check my vent filter, the mechanic also noticed that there was leaking oil near the filter housing. The brake power is so low despite having it serviced for brake assist recall sometime in 2016 despite new Brake pads were installed. I also noticed that the brake fluid was getting lower sometime July 2023. Looking at the list of recalls - these complaints were not addressed by those 3 recalls reported to NHTSA.

I WAS DRIVING AND THE CAR GRINDER TO A HALT. THE BRAKE LIGHT CAME ON AFTER THE GRINDING. I CALLED A TOW TRUCK AND HE FOUND A BOLT ON THE GROUND THAT WAS HOLDING THE CALIPER/HUB TOGETHER. MY SPEED WAS AROUND 30 MPH BUT IF I WOULD HAVE BEEN ON THE HIGHWAY OR AT A HIGHER RATE OF SPEED I WOULD HAVE BEEN IN TROUBLE BECAUSE THE CAR WOLD NOT MOVE. MY BRAKES WERE JUST REPLACED 3 MONTHS BEFORE. ACCORDING TO MY MECHANIC THE HOUSING FOR THE BOLT THREADS WERE STRIPPED. THE BOLT HOLDS THE CALIPER AND HUB. A MACHINIST IS NOW TRYING TO RETHREAD IT. IT WILL BE A WEEK TOMORROW WITHOUT AS HE FIXES ANOTHER BOLT HOUSING IN THE HUB THE SAYS IS STRIPPED ALSO. MY MECHANIC SAID THAT THIS IS SOMETHING THAT SHOULD NOT HAVE HAPPENED ON A CAR LIKE THIS. THIS IS MY 2ND Q7-- SAME CAR ALMOST EXACTLY EXCEPT IT WAS A 2009 AND IT HAD 110000 MILES ON IT WHEN I SOLD IT AND HAD NO O PROBLEMS WITH IT.
