2015 Audi Q5 Engine Problems

Engine consumed a quarter of oil every 300 miles. The EPC light and engine light illuminated. The vehicle went into limp mode. I had the vehicle towed to a certified mechanic.Vehicle was inspected by a certified mechanic and will need a new engine. Engine only has 85,000 miles and oil was changed every 5000 miles.

i have had necessary service checks; however, the spark plugs keep getting burned out. the car is barley 10 yrs old i have replaced the spark plugs 4 times this year alone. Its like every 2 months for the last year. this is abnormal

The contact owns a 2015 Audi Q5. The contact stated that there was an abnormal leak underneath the vehicle. In addition, the contact stated that the vehicle failed to start up as intended. The contact stated that the coolant reservoir was refilled; however, the failure persisted. The vehicle was diagnosed on the scene by an independent mechanic, who determined that water pump had failed. The independent mechanic related the failure to NHTSA Campaign Number: 18V229000 (Engine and Engine Cooling); however, the VIN was not included. The local dealer was not contacted. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 140,000.

Common problem with engine cooling systems and oil systems failing. Failing emissions because of this and overheating with risk of fire. Common problem with the Q5s. Which some of them are recalled but not my 2015 q5 premium for some reason.

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.

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 NHTSA to investigate and take appropriate action.

When I reached approximately 101,000 miles my low oil indicator yellow light came on. The car does not have a dipstick so I could not manually check this. I thought the oil level sensor was broken, as I have not had this light come on in the first 101,000 miles. I regularly change the oil according to manufacturer guidelines of every 10K miles. Eventually the red low oil level light came on and the car told me to add oil. I went and had the oil changed and they told me there was only 2.9 quarts of oil remaining in the car when they changed it. Obviously the car is buring oil as I have no indicated leaks on my garage floor or driveway. I note this is an issue on many online forums. If the negine were to sieze at speed while driving it will be very dangerous.

The contact owns a 2015 Audi Q5. The contact stated while driving approximately 55 MPH, the message "Pull Over Immediately" and a chime started to sound. The contact pulled off the road and placed the vehicle into park (P) and turned off the vehicle down for approximately 20 minutes. The contact was able to restart the vehicle however, the vehicle started to overheat, and the warning lights illuminated. The contact stated that the failure became reoccurring. The contact was able to drive the vehicle to a dealer who diagnosed that the radiator was cracked and lost all coolant, and that the radiator, thermostat and seals needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 18V229000 (Engine and Engine Cooling). The manufacturer had been informed of the failure. The failure mileage was approximately 58,000.

The contact owns a 2015 Audi Q5. The contact stated that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to a dealer where it was discovered that oil had leaked into the engine coolant. Due to the failure, the oil cooler was replaced; however, the failure persisted. The vehicle was taken back to the dealer where an oil consumption test was performed. The test showed that the piston rings were defective and needed to be replaced. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 75,000.

The car presently has about 92,000 miles on it. Around 80,000 miles (back over the winter) the oil light started to come on indicating I'm down a quart or so. I would find myself putting in a quart of oil every 1,000 miles or so. It has progressed. I understand the vehicle has a problem with the piston ring design such that the ring allows excess oil into the chamber and the ring itself might shatter. The problem, at best, prevents acceleration and deceleration...problematic on or off a highway. At worst, the ring shatters and engine stops. The 2012 - 2017 models and other models were involved in class action lawsuits. The 2015 escaped that litigation somehow. Though I'll be taking it to an Audi dealer for an oil consumption test as recommended. No one has yet to inspect the vehicle.

After paying to run an inspection test recommended by Audi USA, it was confirmed that the issue of the excess oil consumption was with the piston, and they also recommended changing the engine. It puts me at risk every time I drive the car because I am not sure how much oil my car has at this point. I have been reporting to the dealer my observation of excessive oil consumption. They kept telling me that it was because my car was old. I have an Audi Q5 2015 with 85,600 miles. I have done all my manufacturing maintenance at the dealer, so they have records that I do take care of my car. I paid to run a diagnostic test suggested by Audi USA. I was told that I have to pay about $30,000 to fix the engine ($13,000 + for the piston and $17,000 + for the engine). The car started warning me that it needed oil soon. I reported it to Audi USA and told them that this issue was one of the recalls done in 2017. I was told that I did not qualify for any coverage because it was only for cars that had an issue in 2017. Now, at 85,600 miles, I am using almost two-quarters of an ounce for every 1,000 miles. I called Audi USA over a month ago, and they asked me to take my car to the dealer so that they could run the test. I had to pay for the test only to confirm that I needed to change the engine and piston. This is a costly luxury car, and nobody should be going through this issue. Audi is responsible for this manufacturing defect.

Cylinder #3 lost compression, down to 30 psi from 170 psi, causing the car to lose power and run extremely rough or not run on occasion. This is a safety hazard, especially risky for highway driving. There were no warning messages, car just start running very rough or wouldn't start. Such loss of compression has been reported by an Audi service manager who says Cylinder #3 is known to have this issue, but there is no recall for it yet. The problems began in May 2021. The car was drinking/consuming oil frequently and occasionally running rough. It was taken to multiple mechanics to identify the issue. Fixes included changing spark plugs, coils, and the PCV valve to provide temporary solutions at best. 5/24/21 increased consumption of oil began 9/9/22 rough idle, spark plugs replaced 10/14/22 rough idle and burning oil, taken to a service shop, replaced the PCV valve 7/12/23 rough idle again, spark plugs replaced again under warranty 2/14/24 - rough shake again, spark plugs replaced again and dead cylinder #3 confirmed

The contact owns a 2015 Audi Q5. The contact stated while the vehicle was stationary, he became aware of a coolant leak underneath the vehicle. The contact towed the vehicle to an independent mechanic and was informed that the water pump was be replaced. The vehicle was not repaired. The contact called the local dealer and made them aware of the failure. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 18V229000 (Engine and Engine Cooling) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 68,000.

A "turn off engine, check coolant level" warning appeared and the engine overheated within the same day. The vehicle was taken to a repair shop who found a faulty water pump that required replacement to fix the issue.

The contact owns a 2015 Audi Q5. The contact stated that a message to “Please add a quart of oil’ was displayed on the instrument panel. The vehicle was taken to an independent mechanic and a quarter of oil was added; however, several weeks later the same message illuminated on the instrument panel. The dealer was contacted and stated that the pistons might need to be replaced; however, the vehicle was not diagnosed. The manufacturer was contacted and stated that the vehicle was out of warranty. The failure mileage was 120,000.

SUV burns approximately 1qt oil per every 250-500 miles driven. Oil is accumulating on engine, causing burn and acrid odor. If I do not add a quart every ~2 weeks, engine will overheat. Have replaced the PCV part twice to no avail. Initially, mechanic recommended replacement of piston rings. Audi must recognize problem as they are no longer selling rings; owner must have complete pistons replaced. This is an expensive fix. This complaint appears common across Audi Q5 owners of this model year. Previous model years were recalled for same issues; clearly the issue was not addressed in later model year either.

The contact owns a 2015 Audi Q5. The contact stated that on numerous occasions while driving at various speeds, extra pressure was needed to depress the accelerator pedal for the vehicle to accelerate as needed. The contact stated that she heard a knocking sound throughout the vehicle. The check engine warning light was illuminated. Additionally, the contact stated that she needed to add one quart of oil less than every 300 miles however, the oil level failed to remain at a normal level. The vehicle was taken to the dealer where it was diagnosed that the pistons needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 132,000.

THE ADD OIL LIGHT ON MY VEHICLE STARTED TO COME ON AS I WAS DRIVING. INITIALLY IT WAS REQUIRING OIL ADDED IN BETWEEN SERVICE APPOINTMENTS. I MENTIONED IT AT TIME OF SERVICE AND I WAS TOLD THIS WAS NORMAL AT THE DEALERSHIP WHERE I HAD ALL OF THE SERVICE ON THIS VEHICLE DONE. WHEN IT STARTED READING LOW OIL AT JUST UNDER EVERY 1000 MILES I CONTACTED DEALER AGAIN WHO HAD ME BRING IT IN AND THEY PERFORMED A SCOPE OF THE SYSTEM. I WAS TOLD THAT IT WAS NOT USING TOO MUCH OIL AND ACCORDING TO AUDI IT WAS WITHIN NORMAL USAGE OF OIL. I WAS VERY SKEPTICAL AND BROUGHT IT TO A DIFFERENT AUDI DEALERSHIP FOR THE NEXT SCHEDULED SERVICE. THEY TOLD ME THERE WAS TOO MUCH OIL IN THE EXHAUST AND IT WAS INDEED USING TOO MUCH. AT HIS POINT I AM NEEDING TO ADD A QUART OF OIL AT JUST UNDER EVERY 500 MILES. I DID GET A THIRD OPINION FROM A FOREIGN MOTOR SPECIALIST WHO WORKS ON AUDI'S BUT IS NOT AFFILIATED. HE TOLD ME THE CAR IS USING WAY TOO MUCH OIL AND THAT THE AUDI Q5 VEHICLES ARE KNOWN FOR THIS. I HAVE HAD ALL RECOMMENDED SERVICE COMPLETED AT AN AUDI DEALER, MOST WAS DONE WHERE THE VEHICLE WAS PURCHASED. I HAVE ONLY USED PREMIUM GASOLINE, WHICH IS WHAT AUDI RECOMMENDS. I AM VERY FRUSTRATED WITH THE CONFLICTING REPORTS AND BELIEVE THIS IS A KNOWN PROBLEM THAT AUDI CONTINUES TO IGNORE. THIS IS AN ONGOING INCIDENT WHICH FIRST HAPPENED AT ABOUT 60,000 MILES. THE DATE BELOW REFLECTS THE LAST TIME THE ADD OIL LIGHT CAME ON.

I HAVE BEEN DEALING WITH AN OIL CONSUMPTION ISSUE ON MY 2015 AUDI Q5 FOR A GOOD PART OF THIS YEAR. I SERVICE MY VEHICLE REGULARLY AND OIL CONSUMPTION HAD NEVER BEEN AN ISSUE UNTIL THE ENGINE LIGHT CAME ON IN MARCH. I LIVE IN FL DURING THE WINTER MONTHS SO I TOOK THE VEHICLE TO AUDI OF MELBOURNE ON MARCH 12, 2020, ODOMETER READING 75,755. AT THAT TIME, THEY COMPLETED PART 1 OF AN OIL CONSUMPTION TEST AND INFORMED ME TO RETURN THE VEHICLE IF THE ENGINE LIGHT CAME ON OR I DROVE 1,000 MILES. BECAUSE OF THE CORONAVIRUS, I RETURNED TO KY AND THE SECOND PART OF THE TEST WAS COMPLETED BY AUDI OF LEXINGTON ON MARCH 31, 2020, ODOMETER READING 76,920. I WAS INFORMED THAT THE VEHICLE PASSED THE OIL CONSUMPTION TEST (NO REPORT PROVIDED) BASED ON THE PARAMETERS ESTABLISHED BY AUDI USA. I CONTINUED TO MONITOR THE OIL LEVEL, ADDING WHEN NEARING THE MINIMUM LEVEL. REALIZING THAT OIL CONSUMPTION WAS WORSENING, I CONTACTED AUDI OF LEXINGTON AND SCHEDULED A SECOND OIL CONSUMPTION TEST. PART 1 OF THAT TEST OCCURRED ON JUNE 23, 2020, ODOMETER READING 77,793. I WAS TOLD TO DRIVE THE VEHICLE UNTIL THE ENGINE LIGHT CAME ON OR I HAD DRIVEN 700 MILES. AUDI OF LEXINGTON COMPLETED PART 2 OF THE TEST ON JULY 21, 2020, ODOMETER READING 78,534, AND AGAIN THE VEHICLE PASSED WITHIN AUDI USA PARAMETERS. I BELIEVE THE OIL CONSUMPTION WAS .49 QUARTS. I PURCHASED THE CERTIFIED PRE-OWNED VEHICLE FROM AUDI OF LEXINGTON ON APRIL 18, 2015. THE CPO WARRANTY IS SET TO EXPIRE ON AUGUST 23, 2020 AND I FEAR THE ENGINE WILL FAIL SOMETIME BEFORE OR AFTER THAT DATE. I KNOW THERE IS A SERIOUS OIL BURN ISSUE THAT I HAD NEVER EXPERIENCED ON ANY OTHER VEHICLE OWNED DURING MY LIFETIME AND WHILE ACCEPTABLE TO AUDI USA, IT IS NOT ACCEPTABLE TO ME. WHILE THE OWNER'S MANUAL MENTIONS MINOR OIL CONSUMPTION, QUART PER 600 MILES, I WAS NOT DISCLOSED THAT ISSUE PRIOR TO PURCHASING THE VEHICLE.

OIL CONSUMPTION - CHECK ENGINE ADD OIL LIGHTS COME ON EVERY 200 TO 300 MILES ADD A QUART OF OIL THEN AGAIN AFTER 200+ MILES ADD ANOTHER QUART. AUDI WILL NOT ACKNOWLEDGE THERE IS A PROBLEM AND RECALL. I HAVE 108K MILES 90% HIGHWAY. 5 YEAR 80K WARRANTY IT STARTED AFTER 80K MILES. I HAVE SPENT $3K THE PAST SIX MONTHS WITHOUT REPLACING THE ENGINE.
