2017 Audi Q5

Coolant tank empty - leaking. Coolant leaking from the thermostat housing to engine. Had to replace the thermostat housing and reseal the valve cover Because the oil leak coming from the valve cover is causing oil to reach the thermostat sear and cause the rubber seal to expand and blow out causing the coolant to leak from the thermostat. This cost me $2,431.00.

On 12/13/25 around 8:00am in the morning. I was driving between 20-25 MPH and started to brake for the corner stop sign. I applied the break as I normally would however, the car continued to roll and did not respond to my applying pressure to the brake pedal. No matter how much pressure I apply to the brake the car continued to coast without stopping. I continued to press hard on the break and even pumped the break. After 2 to 3 yards of coasting, the car stopped. I continued to drive the car for another 0.5 miles and the same break problem occurred again. There are no lights indicating problems on my dashboard. The weather was clear and sunny in the morning. There was no rain. There was no snow. All the roads were dry. I took the car to my dealership and they could not find anything wrong. The brake pads were well within the normal safety range at 8 mm. There was no computer system malfunction. They could not give me an explanation. The Audi dealership’s head mechanic said that because my front brake pads and rotor, and my back brake pads were replaced at Pep Boys two years ago that this could be a reason for the brake failure. although he was not 100% sure of this. He suggested that I pay $3500 for Audi to replace the current rotors and brake pads despite the original determination that there were nothing wrong with them. The auto mechanic test drove the car with me after the diagnostic evaluation. He could not detect any problems with the brakes no screeching sounds no noises. The anti brake system was working well. to this day, I still do not feel safe driving this car for fear that the incident with the brake failure will happen again.

coolant is leaking from pump and tstat housings. pump was replaced in 2018 and 2019 by audi due to audi recall. now it is leaking after only 6 years. seems like faulty materials and creates hazardous situation. leaks confirmed via diagnostics by Premier1 auto and certified technician. first received low coolant indicator light in May. filled coolant. then within a couple of weeks it was significantly low again.

The PCV valve malfunctioned and required an extensive repair bill to solve. I've learned that this very engine (3.0) is already a subject of a recall for this concern, but the recall cuts off at 2016 Audis, and mine is a 2017. Please update your recall list to include ALL Audi models with this 3.0 engine, as the problem is the same regardless of the year.

My SUV had stopped heating/defrosting and vehicles car charging ports appear to not be working any longer. It was discovered that my coolant pump was blocked with debris. The heat has returned, still no power to the charge points in vehicle. While driving on highway, my vehicles dash started to light up instructing me to turn off engine coolant low (electric). However, my H C coolant gauge was just below midpoint. It appears to be a bit faulty. Nonetheless, I pulled off highway and asked a local car supplier store and mechanic shop to look, they reported that it appears to be leaking coolant inside the vehicle puddling the coolant in the undercarriage of the vehicle not leaving any visible signs of leaks on driveway. Please advise.

Steering is occasionally exhibits resistance when turning left or right. Steering becomes very stiff intermittently. I have taken the to a repair twice but the does not duplicate. The repair did a scan to see if there were any codes but none came up. We also have an ODB2 scanner and scan the vehicle right when problem occurred but no codes were displayed on my scanner. My wife has a long commute of 40 miles in each direction and I concerned. There should be a recall as I feel this is a safety issue.
