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.

There was a lawsuit, see link below, because the water pump on 2021 Audi Q5’s fail prematurely. My water pump failed at 66,241 miles and I believe that my 2021 Audi Q5 should’ve been covered under this water pump failure recall. However, my VIN was not included. Link: [xxx] I would like the recall on the water pump to be extended to my vehicle as it’s unreasonable that my water pump failed at 66k. Picture of repair in attachments.

My vehicle spontaneously began displaying emergency signals including engine malfunction, turn signal malfunction, parking brake malfunction, brake light malfunction. I would also turn the car completely off and brake lights would remain on asymetrically. Also, the related alert bells would go off intermittently. I have kept my car in good repair and on a regular maintanence schedule. I took the car first to my mechanic who evaluated and said I should take to the Audi dealership. After two days of diagnosis, they came back that the sunroof drains were clogged with debris which definitively caused water to enter and soak the "comfort module" after irrigating them, they did not find any damage and said they do not need replacement. However, the water soaked and heavily corroded the comfort module and say the entire module needs to be replaced along with a rebuild of the harness. They are quoting me $12,300. My safety was at risk in the malfunction of the engine system, and especially signalling capabilities and possible brake impact. The problem has been confirmed by two mechanics - mine and Audi I searched online and have discovered a number of other 2018 Audi Q5 owner accounts of the same and similar defect and result. [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Fuel pump has been recalled on other models but not mine. I have a 2018 Audi Q5. It had a warranty extension but the previous owner never claimed but if it would have been a recall then I wouldnt be having this problem . Now I have to replace the water pump and pay almost $2k for something that wasn't a recall.

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,.

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.

The contact owns a 2018 Audi Q5. The contact stated while driving 30 mph, the vehicle started to vibrate abnormally with the message "engine fault detected" displayed. The driver was able to pull to the shoulder of the roadway, where the vehicle stalled and was unable to restart. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the connecting rod bearings, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 49,000.

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.

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.

1 steering wheel makes noise. Dealership fixed in December 2024 but same sound come back again. 2 oil burning smell comes while driving.

Audi Q5 shows no recalls on my vehicle. My car stops randomly while driving even while being on highways and interstates. As well as the passenger side leaking due to sunroof drainage coming to the inside (which may affect the air bags). This car has not had any repairs on recalls that I know of personally.

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.

The engine has failed and I am not sure why my Q5 was not included in the recall for coolant issues leading to engine failure. My issue started last winter when the car would suddenly kick in a loud fan. It would flash a warning that the start/stop malfunctioned as it only happened when stopped and/or parked. It was extremely alarming to hear so I would turn the car off and let it sit. When I started it up, there were no warnings and would drive normally. This continued to happen randomly. Then came the coolant low warning, engine temp, along with an rpm warning that kicked on the loud fan. I added coolant as it was the reservoir was low but never empty and temp gauge was in normal range . All messages would go away, car would drive normally. The coolant message happened a couple more times and always the same but eventually did not return. The max rpm and temp continued in conjunction with the start stop messages. It was always the same. It would be stopped or parked with the start/stop engaged. The fan would kick on and increase in severity and the temp gauge always was within normal. I eventually stopped using the start/stop function and it seemed to resolve the issue. The warnings never stayed on so I was not overly concerned since it drove fine and didn't sound rough when the messages and warning weren't active. Then it expelled the oil under the hood and gave zero warning lights. I only figured it out when the oil low warning came on. I thought it was weird because I had just checked the level since I see lots of complaints that Audi burns oil. When I opened the hood, I saw the oil. I know this happened suddenly and was not a leak because I was checking may parking spots. I took it the oil change place and it was cleaned up and replaced. I then took it to have the source of the leak identified but a pressure test revealed nothing. Again, no warning persisted and it drove fine. The next time the oil was expelled, it seized and failed.

My truck was part of a recall regarding my water pump and coolant leaking. I went for service at the naperville Audi dealership and they basically gave me the run around and didn’t honor the recall lied and said they replaced my thermostat and never did. I had my car towed twice on 10/22 basically left stranded. Audi corporate advised them to fix my car due to the recall and they failed to do so.

The comfort control module in the trunk of the car was sitting in water due to an ingress of water coming in the car. The car would not start due to this water ingress and could have shut off completely on the freeway or while driving. This caused my car to completely shut off and malfunction. There were no warning lamps or messages of the problem. I found out about the problem by taking the car to the Audi dealership. They originally thought the problem was the gateway module which has already been recalled due to the same problem of an ingress of water. The Audi dealership has claimed that the ingress of water is from a clogged drain pipe in the sunroof. They said there is nothing you can do to prevent this from happening.

The contact owns a 2012 Audi Q5. The contact purchased the vehicle at an auction, and while leaving the auction site and driving 10 mph, the vehicle stalled. The contact was able to coast to the side of the road. No warning lights were illuminated. The contact jumped-started the vehicle, and after entering the freeway, the vehicle vibrated and failed to accelerate as intended while depressing the accelerator pedal. The failure persisted until the contact arrived at the residence. The vehicle was taken to an independent mechanic; however, the vehicle was not diagnosed. The vehicle remained unrepaired for several days. The contact went to pick up the vehicle, and the independent mechanic stated that the vehicle had been repaired. The contact stated that a week later, while diving at an undisclosed speed, the failure recurred. The vehicle was taken back to the independent mechanic to be diagnosed, and the contact was informed that the spark plugs had failed and caused the engine to fail. The contact stated that the independent mechanic had replaced the spark plugs and that the vehicle had been repaired. The contact was unsure if the spark plugs had been replaced. The independent mechanic refused to repair the vehicle. The contact stated that the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.

Motor mounts leaking, car at only 45k miles Audi dealer indicates fix will be ~$3,200 many posts online (audiworld discussion forums, etc. ) - many drivers encountering issue at even fewer mileage concerning that there was no warning on vehicle.

Car was left outside for two weeks while we were gone on a trip. When we returned and attempted to start the car numerous warning lights went off related to turn signals, tail lights, engine ignition, key recognition, etc. We were able to drive the car home but the turn signals and tail lights were malfunctioning and the engine would lose power unexpectedly. Upon researching on Audiworld forums I came to learn I should check to see if there was any moisture in certain areas, including the rear fuse box area at the rear of the car. I checked that location and found many inches of water in the fusebox!!! I learned that many, many people with Q5s have had the same problem which is rainwater entering the vehicles electrical system due to non-operable sunroof drain ports. Yes, I searched and found an unrelated recall 90s9 but the dealer said this was not the issue, the issue is non-operable sunroof drains and the repair cost is $8,000. Having no idea of the danger I was placing my family in by driving this vehicle while its electrical system was swamped with water, I feel a class action lawsuit should be brought against the company for damages for material, labor, as well as the risk of injury or death I placed my wife and I in by driving this vehicle under such unsafe conditions. I noted there was a suit settled for this issue with other models, but not the 2018 Q5. [xxx] v Audi/volkswagon [xxx] . The idea that someone should have to face death for leaving their car in the rain does not even pass the laugh test. Someone in Audi's risk management department needs to address this and make owners whole again. Please advise. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On [xxx] at around 8:55-8:59 I finalized the paperwork for a purchase of a car, received the keys, drove out of the dealership and by 9:02 the check engine light came on and the car shook. On [xxx] at around 2:22 pm, as I was driving, the car shook, pulled up to red light and the car would not move. It shook, rattled and died. The epc light came on. I owed the car back to the dealership. I noticed that parts of the car next to the muffler and the tailpipe were belong held together with making tape. I received a call from the dealership from tony. He said the car was fixed by the owner. No clear verification that the dealership owner is as trained or licensed mechanic.

The engine mounts on my car began to fail around the 55k, this causes the engine to shift while driving which can not only permanently damage the engine but also cause the car to malfunction and could cause a serious accident. This definitely puts the safety of myself as the driver and others on the road at risk. The problem has been confirmed by an independent service center, and there are many other Audis with the 2. 0 engine that have this same issue ranging as low as 25k miles that I have seen. No warnings or messages, car had began shaking when pressing on accelerator and when shifted in to reverse and braking, making it unstable on the road.

The dash board lights all came on, windows rolled down, car could not be controlled and couldn’t put the gear in park. After further research on the internet, I found that there was a recall on 288,000 q 5s in 2021 because of this issue. Dealer said the “gateway system” that controls all the communication died and they had to replace it. I think the 2021 issue is not completely resolved.

Reverse car went full throttle, brakes did not work, car stopped in reverse when it hit a tree. Seat belt did not tighten,.

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.

2012 Audi Q5 2. 0 engine failure 72,000 miles the dealership performed a tear down of my engine and had an inspector from Audi care come to inspect the damaged engine. It was determined the tensioner /timing chain caused the engine failure. Prior to the inspection, I did research and informed the service manager at the dealership that there was a known issue regarding this exact problem. He said he would have to perform the tear down to determine the cause. He contacted me to confirm it was indeed the cause. Now after more research, I saw there was a class action lawsuit regarding this exact issue. It was settled in 20/& or 2019 , I believe I bought my car in 2020, from an Audi dealership. Who I now assume should have been aware of this known issue and class action settlement. I would like to report this past known issue to the ntsba. I am being told I will have to pay a large amount of money after my extended warranty will only cover a portion of the repair. This was a known problem which could have put me in danger of the engine seizing will operating the vehicle.

On may 3, 2024, while driving to work, the vehicle acutely started to make a loud clicking noise in the engine compartment. I parked the vehicle and looked for a warning light indicator on the dashboard to determine the problem, but no indicator light emerged. I then called Audi omaha and spoke with the service manager who kindly arranged to have my vehicle picked up and a loaner dropped off. I did ask at that time whether it was safe to have somebody drive my vehicle to Audi given the severity of the noise and I was told that since there was not a warning light on the dashboard, it would be ok. I later discovered that my vehicle stalled on the way to Audi omaha and required a tow. On may 6, 2024, I received a report of the problem and the estimate for repairs. It was explained that the head of a spark plug had broken off into the engine causing the piston to make contact with the valve in cylinder 3 resulting in engine damage which was beyond repair. Additionally, a second spark plug had been misfiring for several days. The estimate to replace the engine: $9,282. 03. To my surprise, the multi-point vehicle inspection report I received on the same day reported that everything (aside from rear brake pad wear) passed inspection – including the engine and spark plugs! on may 7, 2024, I called Audi omaha to express my concern that an entire engine would need replaced on a 6-year old luxury vehicle with only 60,000 miles and spark plugs that were replaced at 40,000 miles prior to my purchase of the vehicle. Even more concerning is that no warning light indictor ever displayed on the dashboard (despite being informed that the vehicles computer system had detected changes in the engine compartment 2-days prior to this event). Because of these glaring safety concerns, this issue was escalated to the Audi central region division who declined to provide assistance despite the faulty spark plug and the malfunction of the warning indicator light.

The hydraulic engine motor mounts have failed at 45,000 miles.

3 times while driving engine stalled. Car will restart after coasting off road & restarting it. Been to two Audi dealers under warranty. Car displayed no fault code. Only happens occasionally so neither dealer has seen the problem to fix it. My wife has video of the last engine stall but still no fix. We don’t trust or feel car is safe to drive.
