If I have a sensor that will malfunction due to water then there should be a water indicator alert. My sunroof vent was blocked and water went into my trunk where the core module is. I had just come to a red light to turn on to a major highway and my car began to smell like fuel. I rolled down the windows and realized the smell was not as strong as inside. The light turned green and as I stepped on the gas the car went into limp mode as I was in the middle of my turn. The power steering then went out in the turn...

and the wheel yanked to the left and put me half way into the lane next to me. Thankfully no one was there. I had to yank it back to the right to get off of the highway on to the side of the road. I do not think that the power steering should be associated with that module or at least a water indicator sensor should be added. What happens if someone is on the interstate is driving 75 mph and their power steering goes out. It's in the shop and there is no damage other than now I am scared to drive it

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.

There was a lawsuit, see link below, because the water pump on 2021 Audi Q5's fail prematurely.

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.

Vehicle: 2015 Audi Q5 2.0T VIN: [[redacted]] 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.
