2014 Audi Q5 engine problems

ENGINE

I am filing a safety complaint regarding a progressive engine defect. Beginning as early as 2019 (approximately 84,000 miles), I repeatedly reported excessive oil consumption and related engine concerns to authorized Audi dealerships. These complaints continued over several years. At no point was I informed that these symptoms could be associated with a known defect pattern or progressive engine failure. The condition has now escalated to a severe engine malfunction. The vehicle began exhibiting engine misfires, flashing check engine light, EPC warning, and unstable operation. The dealership confirmed misfire fault codes and oil contamination affecting the ignition system. Engine replacement was initially recommended. Excessive oil consumption leading to internal contamination and misfires presents a significant safety hazard. Loss of engine power or sudden failure while driving can create dangerous conditions, particularly at highway speeds or in traffic. Despite the long history of reported symptoms, Audi of America has declined to provide assistance, citing only warranty status and failing to address the defect progression. The vehicle has now been inoperable at an Audi dealership for approximately 60 days (nearly two months), with no resolution. This situation raises concerns regarding a safety-related defect, failure to disclose a known issue, and a potential broader pattern affecting similar vehicles equipped with this engine. I am requesting that this issue be reviewed for potential defect investigation. The dealer provided diagnostic findings with Failure Codes via a temporary link that is no longer accessible. I am requesting a copy of the full report and will upload this (once received), along with other documentation.

Under Recall 19N4, the electric coolant pump was replaced in July 2019 at 73,496 miles. That replacement pump failed prematurely in March 2025 at 109,628 miles — lasting only 36,132 miles. This was a safety-related recall part intended to fix a known defect with the original pump. Audi refused to provide goodwill reimbursement for this premature failure. I am reporting this to request further investigation and possible expanded remedy.

I have noticed 2 times that my engine burn out oil very quick before the next predicted oil change and lead to safety risk of boosting engine while driving long distance if there is no auto one near. After speaking with one of the maintenance guy the last time I went for oil change at Jiffy live, He told me that there was a recall for the same problem with some other Audi models. How could we expect your help to address this safety concern with the manufacturer. This is very dangerous situation that you can’t neglect. Best regards,

The contact owns a 2014 Audi Q5. The contact stated that while driving 60 MPH, the vehicle briefly lost motive power and the vehicle stalled. The contact was able to coast to the side of the road. No warning light was illuminated. The vehicle was towed to the daughter's residence. The contact stated that weeks before the failure, while the vehicle was being serviced at the dealer, it was determined that the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The manufacturer was made aware of the first failure. The failure mileage was 72,919.

Vehicle stopped while driving!!! Middle of the driving. Very dangerous. And it happened twice. With that as the headline, another known problem with this vehicle has been the engine oil needing to be filled literally every month. And time to time it resulted in “engine light” to come. So we kind of ended up in a “wolf cry” and really didn’t act. However, we did take care to Audi service for oil refill and they IGNORED to do the inspection on engine light well under 100,000 miles and 10yrs on warranty. So our recent car stopped when we were just about 2 months over 10yrs and 3,000 miles over 100,000 mile warranty Audi has for the problem needs repaired. Please help. Now Audi is saying we needed to pay almost $6,000 to get that repaired. Which they have seen for months prior to the 10yrs and 100,000. It’s really a unfair business practice.

The car has a known "oil consumption issue" that has led to engine failure that Audi has failed to take responsibility for. This is a 2104 Audi Q5. The car is in San Francisco and available for inspection. The car vibrates and can't be safely driven at highway speeds, if the engine suddenly lost power on the highway it could be a major safety issue for the driver and other drivers. The dealer has reproduced the issue and diagnosed it as needing new Pistons and Rings at 99,000 miles (but it has had this issue since in the 60,000 mile range, they just said keep adding oil). It has not been inspected by police or insurance representatives, just the dealers. I'm sure some warning lights came on, but could not say which ones or when.

In 2017 while driving in 10 degree weather, the overheat warning light and message to turn off engine came in. The car was not actually overheating and we took it straight to the dealership. They were not able to get it to replicate and advised it was possibly a faulty sensor. Fast forward to fall of 2023, the same warning light came on as soon as the car was turned on. Still no actual overheating per the dial in the car. We did check the coolant level and it was low. Dealership looked at and stated the didn't see any leaks and suggested replacing thermostat. Took to another shop and they found a small leak in the water pump so we had it replaced. Car has less than 60k miles on it. Engine failure, fire are all concerns. Especially when commuting at high speeds on a highway. We're either dealing with a faulty water pump or thermostat.

I bought my 2014 Audi Q5 in September of 2019 with 74, 291 miles from a reputable dealership in Cleveland, OH. After a few months of driving, I began to notice that the vehicle did not retain oil. This caused oil leaks which led to internal spillage, subsequent parts damage and random stalling. As a result, in May of 2022, during rush hour traffic, my car failed to accelerate mid-intersection, leaving myself and my passengers in danger of collision. After dealership and independent inspection, it was determined there was an issue with the piston rings in the 2.0 Turbo engine. After speaking with the mechanic, Audi USA and conducting online research, I found that this has been noted and reported to Audi on several occasions for makes and models dating as far back as 2012. Because this is major engine issue, I fear for what other repercussions may result from the negligence. Upon further research, I also found that several class action lawsuits have been filed country-wide due to concern of this factory malfunction. These vehicles are large and capable of irreparable damage. Whatever steps can be taken to avoid sudden engine failure similar to my own is of highest priority.

Timing chain, turbocharger and high pressure fuel pump has to be replaced for the car with 75000 miles on it. Was advised by the shop supervisor that it’s caused by faulty engine. That this type of damage is highly unlikely for the car under 100000 miles. Turbocharger is under extended warranty from the previous Audi recall.

ENGINE

My 2014 Audi Q5 2.0L Turbo, at 84339 miles, is consuming oil between oil changes. 4300 miles after my last oil change by the Audi dealership, I had to add oil. The dealership, Gwinnett Audi, 3190 Satellite Blvd, Duluth, GA 30090, said that Audi is paying for the oil top off for all customers. Seems odd that if this is normal that Audi would voluntarily reimburse the dealership for this expense. I am concerned, based on internet searches, that this will continue to get worse and I will be adding more and more oil without getting the problem resolved. The dealership told me it would cost $7,000 to fix the engine and there is no longer a warranty. This vehicle should not be burning oil at $80,000 miles. Audi needs to make permanent repairs to fix the problem, not just put a bandaid on it. I am not the only Audi owner with this problem.

I am writing about an incident that happened to my wife while she was driving my car from Los Angeles, CA to Phoenix, AZ on June 16, 2021. My wife was driving the Audi Q5 at approximately 75mph and 125 miles west of Phoenix (near the CA/AZ border) when the car suddenly loss power. She stepped on the gas and noticed the speed gradually dropping. Fortunately, she had the presence of mind and barely had enough time to pull over to the shoulder. It was at this point that she called to tell me that the car would no longer start and the “check engine” and “EPC” light indicators were illuminated. This occurred at approximately 12:30 noon during a severe heatwave where the outside temperature was 117 degrees. I asked her to wait for 10 minutes to try to restart the car; the car would not restart. She called AAA Towing and was told the wait would be over one hour because of the rural location (Quartzsite, AZ). She ended up waiting a little over 3 hours in her car, without air conditioning, in 117 degrees for a tow truck driver to arrive. The car was towed to her sister’s house in Goodyear, AZ at a cost of $673. The next day, she had the car towed to the Audi Dealership in Peoria, AZ where it was diagnosed the car had suffered a fuel vapor lock due to the heat. The car has less than 28,000 miles on the odometer when the incident happened. Audi Peoria kept the car for a couple of days because the parts had to be ordered from Los Angeles. Ultimately, the repair bill from the dealership came to $1,983. I felt helpless and scared for my wife that I was not able to assist her as I was 3 hours away. What if my wife (or another driver) was unable to pull over to the side of the road? The chances of an accident are dramatically increased if the vehicle was stuck on the highway. As you can imagine, my wife has been traumatized by this incident and we are both fearful that this incident can happen again. Therefore, we request that NHTSA investigate this incident.

This SUV has a 2.0 engine that consumes oil. I have to add a quart every 200-300 miles as the IP light indicates the engine is at the minimum oil level. This is not normal to be adding oil this frequently. Audi/VW has had problems in the past with vehicles that used excessive amounts of oil and a settlement was reached with owners. It seems they have not fixed the issue and I believe an investigation is needed and corrective action should be taken again by Audi/VW to make owners whole and to finally fix the problem. They need to find the root cause of this problem and fix it.

UNDER RECALL 18V229000 (AUDI RECALL 19N4) MY VEHICLE HAD THE POWER TO THE AFTER-MOTOR PUMP DISCONNECTED IN OCT. '18. INSTRUCTIONS PER THE RECALL NOTICE AND THE DEALER WAS THAT REPLACEMENT PUMPS WOULD BE INSTALLED AS THEY BECAME AVAILABLE IN EARLY '19. AFTER NOT RECEIVING ANY NOTICE FROM AUDI THIS SPRING, I CALLED THE DEALER TO INQUIRE ABOUT THE REPLACEMENT PUMPS. I WAS TOLD BY THE SERVICE MANAGER THAT "AUDI DECIDED NOT TO REPLACE THE PUMPS AFTER ALL". YOUR SITE CURRENTLY SHOWS THAT MY SPECIFIC VIN IS CLEAR OF ANY RECALLS, SUGGESTING THAT THE ORIGINAL RECALL NOTICE WAS MODIFIED IN SOME MANNER TO NO LONGER SHOW THAT THE PUMPS NEEDED TO BE REPLACED AFTER ALL. YET MY VEHICLE IS SHOWING-UP ON WEBSITES LIKE CARFAX AND AUTOCHECK AS STILL HAVING AN OUTSTANDING RECALL DUE. SO I NEED CONFIRMATION OF EITHER 1) AUDI IS STILL REQUIRED TO REPLACE THE PUMPS AS THEY AGREED TO IN THE ORIGINAL RECALL, OR 2) THEY HAVE BEEN RELIEVED OF THAT REQUIREMENT AND THAT MY VEHICLE IS TRULY CLEARED OF ANY FURTHER ACTION. THIS IS VERY IMPORTANT AS I AM ATTEMPTING TO SELL MY VEHICLE...AND WITH THE RECALL STATUS SHOWING OPEN ON PUBLIC SITES, IT APPEARS THAT I'M TRYING TO SELL DAMAGED GOODS. THANK YOU FOR YOUR ASSISTANCE!
