Driving on highway at 70 mph and high engine temp light came on. Said to pull over and continue to run car until temp decreased. I got over as quickly as I could ( no more than 1/4 of a mile) and sat on side of PA turnpike as engine cooled. I was at bottom of an exit ramp. I slowly proceeded up the ramp and warning came on again and red temp light reached again. I pulled right into the gas station at top of tp exit ramp. It still said to continue to run the car. I sat with my son in the car and ran the car in the shade. The temp was decreasing and then all my electrical lights came on, yellow battery warning light on and then suddenly the red battery light and all systems failed. Car turned off. Called aaa to take to my mechanic as Audi was a 3 hour wait for a tow and 3 weeks for service appointment with no loaners available. My certified mechanic said water pump completely dislodged. He replaced water pump, thermostat (which was already replaced bc it failed in year 2 of ownership). After repair, 48 volt battery would not take a charge. Assumed faulty alternator and/or battery. Alternator was already replaced once at year 1 as car died while driving as well. We had car towed to Audi and they are reporting known issues with water pump but not issuing recalls. Also known issues with alternator repair parts that were used in year 1 but no warning to consumers. They are diagnosing problem now and if alternator and subsequent battery issue, it will be covered but not if battery issue comes back as electrical in nature.
I have heard a knocking and experienced sudden loss of power while driving- not electrical loss, but vehicle suddenly slows down and unable to pick back up speed effectively creating a safety concern when driving- especially at on ramps. A warning light comes on and then it will go off randomly with the loss of power. I have taken it in multiple times and was told it is an emissions issue and a vacuum hose issue that allows fluid to get into my turbos or something along those lines. I have both been told by my Audi service advisor and done my own research and seen there have been issues with previous years and ultimately a recall was done to fix those- my vehicle is the 1st year following previous recalls. I have been told by the service professionals that they are at a loss whey a recall has not been issued on this issue again. That it is not only an environmental concern, but a huge safety concern. I have contacted Audi America twice now regarding this and zero has happened.
I am writing to report on the results of a call on 08-01-22 to Audi USA regarding the current recall on Audi Q7 automobiles. I asked if the car was safe to drive and the representative could not answer the question. Her comment was that Audi has not issued a stop drive action. The recall notice states ". . . There may be a sudden loss of engine power or the vehicle may break down without a warning appearing beforehand. " this would seem to indicate that it is not safe to drive the vehicle. Our vehicle meets all the criteria mentioned in the recall as being effected. However, the Audi USA representative instructed me to contact my dealer to get the car assessed. The dealer was contacted and we were told they are waiting on guidance from Audi USA and there was no reason at this time to bring the car in for evaluation. In short, we are very concerned about driving this car from a safety standpoint and Audi USA has done nothing but identify the problem without any solution as of today. It should be noted that we have not experienced any problem yet, but given the unknowns of this situation, we are hesitant to drive the vehicle. Any help in causing Audi to resolve this problem would be greatly appreciated.
