Audi Q5 oil consumption problems

Filed Jun 15, 2026 · Engine · KS

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.

2022 Audi Q5 (VIN: [XXX] ). Engine lubrication system failure — persistent abnormal oil consumption across two separate engines over 14 months. Beginning March 2025, the low engine oil warning light began activating repeatedly, sometimes after as few as 300 miles. AutoNation Audi Bellevue confirmed 1 quart low and initiated oil consumption tests. Their technician noted in writing that oil found externally was "not enough to cause a 1 quart low oil light" — meaning the root cause was never identified. A PCV valve replacement was attempted July 2025; the warning returned after only 300 miles — same as before the fix. Audi of America approved a full engine replacement in September 2025, completed December 2025. Within weeks of pickup in January 2026, the low oil warning activated again on the brand new engine, and again after 4,000 miles in April 2026. The defect has persisted across two engines despite multiple repair attempts. Audi now claims consumption is "within spec" at 0.16 qt/1,000 miles but has not explained why the warning light keeps activating. Safety risk: unpredictable oil loss risks sudden engine seizure at highway speeds with insufficient warning to stop safely. Confirmed and inspected by AutoNation Audi Bellevue and Audi of America. Vehicle available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Piston rings failure, large oil consumption and water pump leaking

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.

I have owned the car for 2 years, purchased a 2018 Q5 from an Audi dealer. Within the first year, my thermostat failed causing the car to lose power and turn off while driving with my newborn baby. I also received the passenger airbag alert daily, which I did see there was a recall for this prior to buying the car. I also received the “add a quart of oil” message about 3 months after an oil change. I would like this car to be reviewed for excessive oil consumption. At the times of these messages no oil leak was found. Now, my car went in for an oil change and an oil and transmission oil leak has been found. Within 2 years of owning a car that has had regular maintenance, I have spent over $6,000 on service and repairs, which is unusual. I need help.

Audi had Valves and pistons fail on the highway at 75mph on Nov 28,2024 at 117000 miles Had the vehicle since 2021 and 17000 miles. Complained to the dealerships at the last 3 oil changes about excessive oil consumption. They told us not to worry about it, full aware that they had lost a lawsuit over this very issue. We were never informed about this lawsuit, and now Audi refuses to fix THEIR problem. We are very lucky when the engine blew up that there was no one behind us, otherwise it would have been a major highway accident. Now Audi wants $18,000 to replace the engine.

• Excessive oil consumption • Engine knocking • Illumination of the check engine light, possibly for cylinder misfire • Engine stalling- • the pistons unexpectedly fail, drivers may also experience a sudden loss of engine power while operating their vehicles. This can pose a safety risk as it may become difficult for drivers to brake, accelerate or control the steering wheel. Drivers are believed to have experienced problems with the pistons well before they should, with some seeing engine failure before the 75,000- mile mark. Audi Vehicles Burning Too Much Oil A number of Audi drivers have posted complaints online that their Q5 vehicles are burning more oil than they should, an issue attorneys suspect could be related to a defect in the pistons. A sample of these complaints can be found below [sic throughout, emphasis ours]: My Audi Q5 2012, like all suffers from excessive mass oil consumption. A Dealer did the oil consumption test and said the piston and rings need to be replaced. I ve Already spent over $1K on crankshaft repairs etc. Will AoA to pay for new piston and rings? Its a $6K repair that I am unwilling to pay because it should not be going through this crap for such an expensive car.” This "benefit" likely won't me customers due to the age of the vehicles and they don’t seem to care. Not to mention owners will still be stuck with paying a percentage for repairs. I bought a 2012 Audi Q5 in in 2015…For the first 20,000 miles of owning this car, it was my dream car and was all I had hoped for. Then, the check engine and oil light game started. At first, adding oil meant that it would it go another 1500-2000 miles without issue. Then, around 75k, it went to 500 to 750 miles. Once it hit 95k, it dropped to every 400 to 600 miles that it needed oil. I am at 118k and desperately want to dump this lemon. Unfortunately, I have payments on this garbage car. I've spoken with a local mechanic about it and he says the fix is replacing the engine.

I've reported multiple times to my dealer about the oil comsumption back in 2022 and work was performed on the vehicle in the prior year to fix leak and brake noise issue since approx 2021 on my 2015 Q5 that currently only has 65,000 miles. No warning indicator presents regarding the brakes. However oil indicator and engine light icons display. I'm constantly checking the oil indicator level to see how much is still in the and then add add once it shows thats its extremly low. I have to do this everytime I am about to use the car. This can be dangerous at times since there's no indication that its very low and its not seen unless you go into the "car" section that shows the level, it has no alert display for the level. All required diagnostic and maintenance services have been performed with the dealer. When inspecting the brake issue they always come back with no findings say that no issue could be found, howeve when I'm driving it, it sqeeks and makes a grinding sound all the time. This has been going on for quite a few years. As for the oil consumption issue, this isssue has been in recent years and both times this has been looked into by the dealer I was informed that its not covered under any manufacturers warranty and would cost me approx. $10,000.00 for them to repair it or I could trade it in. This is a very expensive luxury car and at this low milage shouldn't have these types of issue. I've seen on various car sites that both the oil comsumption and piston issue is a known issue with this model Audi and that issue occurs aournd 60,000 miles but was rectified for the models that came after 2015. I wish I had know this before making this purchase. Now the driver seat adjusting panel is broken, this came out of no where about four weeks ago with no warning. I haven't received any recall notifications since my Audi Care coverage expired, not sure why this would stop because I didn't continue this service.
