general problems of the 2013 Audi Q7

Lights on dash were flashing in cluster which made it look like it was low tire pressure. I had a portable air pump which showed tires were fine. The vehicle went into some kind of limp mode which prevented the vehicle from driving the speed limit. It was taken to auto service center. The diagnosis was engine failure due to a burnt valve. It's been confirmed through the dealership, mechanics and consumers that is a common problem with this particular make and model vehicle. This engine failure left me on the side of the road and not feeling safe at all while being approximately 3 hours from my home. As an Audi owner I'm was so disappointed to be told that I needed a new motor even though it still runs in limp mode. This vehicle has less than 150k miles. It was the best european vehicle I ever owned until it wasn't. Bad call and poor quality control Audi!.

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.

Coolant leaks is a major concern and I have been asked by local indy on water pump replacement to be done. Its costing me around 1500$. With so common issues, I think Audi should recall and substitute on their own case rather than every customer paying it.

The vehicle has performed poorly after completing a us department of justice mandated "fix" of diesel (3. 0 liter tdi, engine code cnrb) emissions equipment related to vw/Audi emissions cheating. There is now sporadic lag in acceleration, especially at low speeds, or accelerating from a complete stop. There were times when I have pulled into oncoming traffic, and the power delivery was non-existent, followed by, after a 1 second delay, rapid over acceleration. There have also been many problems related to the reductant metering module failure that has caused dangerous delays and lags in acceleration.

Within 300 miles of the diesel recall modification the engine lost power at 70 mph and slowly drifted to lower speed. Additionally the transmission did not respond to manual shift to a lower gear (it stayed in 8th). After stopping the car and turning it off a "reset accoured" and the car operated normally for another 300 miles. The car again lost power and the transmission did not respond to manual shift to a lower gear. The car was taken to Audi and they "cleaned" the erg valve. The loss of power and lack of transmission accrued again at about 300 ,450 and 600 miles past the event of Audi working on the ergt. All of these events have taken place at interstate speeds and when the car is being operated on trips in excess of 300 miles.
