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 was driving down the road when the steering stop working and I could not control the direction that the tires moved. The direction of steering would not respond to my movements and I was unable to control the car. I was able to break and bring the car to a stop, however, if I were moving at a much faster speed this would have been extremely dangerous. I brought the car to our mechanic and we were informed that the tie rods were broken, the threading on the attachment pieces was completely rusted out and the threads were bare. The piece simply came apart and was malfunctioning. No warning signs or service lights came on in the vehicle before this happened and we had no indication that there would be an issue with the steering when operating the vehicle. Our mechanic told us this was one of the most dangerous things he's ever seen happen in a car and that our life was at risk. We regularly have our car inspected and serviced and there was no indication that this would happen. Our car had a major engine problem in August 2023 and was at the Valenti Audi Dealership in Waterbury, CT, during that time the car was inspected and we were not told the tie-rods had any problems.

We have never had an issue with the vehicle until we recently faced very cold Temps (-10 to -20). Was driving the vehicle, with no issues, and stopped to get gas. Upon restarting the vehicle it displayed a power steering error with a do not drive. The steerling lost all power steering function and was extremely hard to turn. We let the vehicle sit and restarted it 3-4 times and on the fourth try, the error went away and there was no further issues with the power steering on this (first) occasion. This has now happened intermittently since the first occurrence (even with very cold Temps) but with no regularity. Not sure if this is a malfunction or if there is something in need of replacement. It is extremely concerning.

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 NHTSA to investigate and take appropriate action.

Rear subframe rusted out at only 85,000 miles

2015 Audi Q5 Quattro (all wheel drive). During recent inspection the vehicle was found to have extreme corrosion, cracking, and structural failure of the rear subframe and subframe crossmember. The rear steel subframe is manufactured as an assembly. The rear subframe assembly supports all of the rear suspension components and rear drivetrain and drivetrain components. My vehicle is always garaged and no other corrosion was found during inspection of the entire vehicle. The finding is a manufacturing defect that is only isolated to the rear subframe assembly of the vehicle. Due to the extreme nature of corrosion and cracking found on the subframe assembly this should be considered a high priority warning for Audi Q5 owners. A total failure of all rear suspension and drivetrain components may result.

The vehicle was towed to a service station where it was inspected and determined that water had leaked through the sunroof and the surrounding foam needed to be replaced. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 17V001000 (Visibility, Air Bags). The vehicle was not repaired. The manufacturer was notified of the failure and the contact was advised that the vehicle needed to be diagnosed at the dealer, but no further assistance was provided. The failure mileage was approximately 30,000.

Driving on the highway the panoramic sun roof window shattered. Sounded like an explosion. Glass shattered and flew throughout car and blew away. Posed hazard to those in car as the glass shattered. Could have caused hazard if driver did not maintain control due to sudden sound and sudden incidence. Extremely dangerous.

This is terrible for this quality of car and price!! I am furious!!

Recently purchased a used vehicle from this dealership that there is a major issue with the drive train including the cv axel and also an issue with the tires that are on the vehicle. One of the tires had gone flat so I took it to the local Les Schwab to have it inspected and was told that I could not repaired it and that they could not sell me and put on the one tire because the vehicle manufacturer size was not met and that it can cause a danger on my 2015 Audi Q5 premium plus. The tire size that was on the vehicle that was purchased is 255/35ZR19, the manufacturers size is 235/55R19 per the les Schwab it can damage the vehicle and decrease the performance of the function of the vehicle which also impacts the speedometer reading and also the mileage tracking adding additional strain on the vehicle as well as decreasing its value faster. The vehicle is an all-wheel drive car and have the incorrect size is a safety concern as well as increasing the amount of mile that are driven that are artificial, also messing with the speedometer reading to have to go 10 mile over the limit to make it go the correct speed, this makes the computer think the vehicle is driving more mile than it is. I have informed the dealer of the issues, and they have refused to help and state that there is nothing to be concerned about. This information was not disclosed to me when purchasing the vehicle.

System does no longer work. Audi Montgomery inspected the vehicle and deamed that both side blind spot warning components have failed. People come to trust the system and when it fails they would lane change, not be warned and cause an accident. Dealer comfirmed failed components. Opened a concern with Audi USA and was told I am responsible for repairing the failed system. 6/19/2025.

VEHICLE RANDOMLY DISENGAGES THE CRUISE CONTROL FOR NO APPARENT REASON, I.E. DRY CLEAR ROAD CONDITION, NO FAULT LIGHT OR ISSUES WITH ABS/TRACTION CONTROL, NO FAULT CODES, ETC. *TR

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.

Complete hydraulic brake failure while on an interstate going 75mph. No warning, just sudden loss of regular and emergency brakes. I was able to cross 4 lanes of traffic to get to the shoulder where I waited absolutely terrified of being rear-ended for the two hours it took for a tow truck to arrive. My repair place was shocked at the problem, considering the car was 8 years old with low mileage. They found the only after-market part in the entire country and repaired it for under $2000 when they initially thought it would be $6000.

Level sensor on left rear suspension failed, causing headlights to be pointed downward and not safely lighting the road ahead. The sensor failed due to poor design, metal-to-metal ball and socket linkage in a corrosion-assured location under the car. When the metal-to-metal ball and socket corroded and froze, resulting load caused the sensor linkage to break. A search of Audi forums indicates that this problem is not uncommon, and this same sensor design is used in other Audi models and variants.

VEHICLE IS VERY UNSAFE TO DRIVE AT NIGHT. THE LOW BEAM HEADLIGHTS ONLY PROJECT AND ILLUMINATE A VERY SHORT DISTANCE IN FRONT OF THE VEHICLE. IT WOULD BE NEARLY IMPOSSIBLE TO AVOID A PEDESTRIAN, ANIMAL, OR DEBRIS IN THE ROADWAY BECAUSE OF THIS SHORTCOMING.
