The cooling system failed without warning! As I’m driving on the highway my vehicle began smoking! I smelled a burnt smell! Upon getting off the highway , I noticed my coolant had leaked almost completely out! I check my vehicle every morning before work as I drive through three counties to get to work and my coolant was full as I had just topped it off that morning! Upon inspection it was found from a local mechanic to be the water pump! My truck was fine last month upon getting a n inspection.

Vehicle: 2015 Audi Q5 2.0T VIN: [XXX] At around 70,000 miles, my vehicle began consuming engine oil abnormally. I received a low-oil warning and had to add 1 quart every 1,000 miles. I first approached an authorized Audi dealer at 75,000 miles, who inspected the vehicle and stated this was “normal for older vehicles” and found no issues. However, the problem worsened rapidly. By 79,000 miles, I visited a second Audi dealer who acknowledged that this was a common problem in this engine type. They quoted me $16,000–$20,000 for a full engine replacement, stating they could not replace pistons alone. At 80,000 miles, my car now consumes 1 quart of oil every 200 miles. The oil warning light comes on frequently. I am forced to carry oil and top off multiple times per week. This is not normal wear for a luxury vehicle with regular maintenance. This condition creates multiple safety risks: •Sudden engine seizure or power loss if oil runs too low, especially while driving at highway speeds. •Loss of steering/brake assist due to oil pressure failure. •Increased fire risk from leaks or overheating. •Frequent roadside stops to add oil, risking exposure to traffic. •Distraction while driving due to monitoring oil levels. •Environmental hazard from oil spills. The engine remains available for inspection. The vehicle has only been inspected by Audi dealerships. Audi should be held accountable for a defect that compromises safety and reliability at relatively low mileage. I urge the federal safety agency to investigate and take appropriate action.

in 2017 Audi repaired a leaky fuel pump in my Q5 due to a recall. My vehicle now has less than 35k miles since that repair and the new-replacement fuel pump flange is failing again. Fuel was coming out and created a significant fire risk to life and property. Audi has refused to deal with the issue and speaking with mechanics at 3 dealerships revealed that the replacement parts are failing at an alarming rate. I would like this looked into.

Faulty pistons, piston rings and piston heads responsible for excessive oil consumption. Excessive oil consumption occurs because the combustion chamber is not properly sealed off from the Audi turbo engine parts that need to remain lubricated. Because of inadequate lubrication, fragments of the piston rings flow through the Audi 2L turbo engines and damage important components. As a result, our 2015 Audi Q5is at risk for immediate loss of engine power. There is currently a class action law suit against Audi for this problem for cars in this year range, but nothing has been solved.Audi's answer to this problem is to bring the car in every 300-500 miles for free oil top offs. This does NOT solve the underlying problem nor eliminate the deadly risk of total engine failure. People are driving around in vehicles at risk for complete failure. The Audi dealership states that to replace piston rings, it will cost between $10,000 and $12,000. Absolutely unsafe and unacceptable.

The car is using/burning excessive oil. I’m adding oil every 300-500 miles. There was an open recall in the past for the exact same consumer problems. I purchased this car used in April of 2022 and it’s been an on going problem since I’ve had it.

I have an audi tdi that the diesel emissions recall was completed. I brought to the attention of my service advisor - dealer, that when the outside air temp is warm/hot and the vehicle is warmed up, there appears lag in the acceleration then suddenly there is a quick burst of speed where the vehicle catches up to the foot accelerator position. Lifting the foot off the accelerator aids in slowing down but I am concerned that if another family member gets in the car there might be a different understanding of what the vehicle is doing. The dealer service advisor did not note this condition on the list of complaints - things to fix at last service. He did state that all the vw-porshe-audi diesel vehicles are dealing with similar issues and that I just needed to adjust my driving, there is no current resolution for the condition. I feel that there should be a better answer from vw-porshe-audi to resolve this concern with the highly skilled engineers they employ!

Car smells when turning the heater on. Car still does not have a fix for the emission. Even if the emission is fixed I still need to increase gas/ad-blue.
