   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.

11. Filed Aug 19, 2025Failure Aug 8, 2025Chesapeake, VASuspension

    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.

    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.

    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.

    To Whom It May Concern, I am writing to formally report a serious safety issue involving my 2015 Audi Q5 TDI (VIN # [XXX] ), which has developed severe corrosion on the rear subframe. I am the original owner of this vehicle, which has 92,700 miles and has been garage-kept and exclusively serviced by authorized Audi dealerships since purchase. On [XXX], following a failed Virginia State safety inspection, the vehicle was inspected by Audi of Chantilly, VA. Their service department confirmed that the rear subframe is cracked due to extensive rust and recommended immediate repair. I have attached both the inspection report and supporting photographs. This is not an isolated case. Numerous Audi Q5 owners have documented similar corrosion on the rear subframe, often attributed to a plastic cover that traps moisture and accelerates rusting. This appears to be a design defect with potentially dangerous implications. As it stands, the vehicle is not drivable. The compromised subframe poses a serious risk of structural failure while in motion, increasing the potential for loss of control, a crash, or injury. The dealership has estimated repairs at over $9,000, which I am currently seeking coverage for through Audi Customer Service. However, Audi has indicated that their corrosion warranty covers only body panels—not subframe components—despite the fact that the defect stems from their design.

    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.

    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.

    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.
