"Front Right Side Marker Light Defective" Error
Filed Oct 25, 2026NC
In XXX, my 2017 Audi Q7 3.0T unexpectedly lost engine power while traveling approximately 70 mph on a highway in [XXX]. A "Drive System Malfunction" warning appeared. The driver pulled over, shut off the engine, and restarted it; the vehicle then drove normally. The sudden reduction in power at highway speed created a risk of collision with surrounding traffic. The precise cause is UNKNOWN. I reported the highway-speed loss of power and warning to Audi Wilmington. At its XXX visit (102,255 miles), the dealership documented the warning and multiple engine misfire codes. It identified a vacuum leak at a broken oil-fill pipe neck, replaced the pipe, cleared codes, and reported no issue during its test drive. The intermittent power loss did not recur during that visit. The vehicle also had recurring excessive oil consumption. In XXX (104,261 miles), Audi Wilmington found it approximately 1.5 quarts low and documented possible piston-and-ring replacement if proposed treatments failed. Those proposed repairs were not performed. In XXX (approximately 109,320 miles), the vehicle again showed a Drive System Malfunction warning and check engine light. Maguire Audi documented multiple misfires and a persistent cylinder #2 misfire after service, and suspected internal engine damage. The vehicle has been out of service since then. Independent testing in XXX confirmed cylinder #2 had 35 PSI compression and 100% leak-down, with part of an exhaust valve missing and oil on the piston. The con

The contact owns a 2017 Audi Q7. The contact stated that while driving 25 MPH, an inoperable passenger’s side front headlight assembly warning light illuminated. The contact stated that the headlight was functioning properly even though the warning light was displayed. The manufacturer was made aware of the failure by telephone. The contact expressed concerns that the warning failure posed a safety risk because the contact might not be alerted if the headlight failed. The approximate failure mileage was 54,921.

I was backing out of a retail shopping parking lot and heard a loud bang, then a horrible noise from the front driver side. The car went on a lock down - was useless. The front driver wheel was pushed out and we could see control arms. broken underneath. I had no warning, no indicators on the dash- this was catastrophic. I was stopping traffic from passing and required police assistance. The car had was towed via flatbed to a Firestone repair shop. As mentioned, no warning - I am certainly glad I was just backing out and not driving on the highway.

The vehicle has a recurring electrical failure involving the camshaft position sensor circuit (DTC P0365). The sensor itself is functional, but the wiring harness leading to the sensor develops internal copper fatigue due to a design flaw in the factory routing. The harness is bent tightly behind the passenger-side cylinder head, causing vibration-induced internal wire breakage that is invisible externally. This failure is well known to Audi dealers and has been reproduced and confirmed by multiple service centers. The problem is not caused by the sensor, plug, or engine components. It is caused by the wiring harness design, which repeatedly fails in the same 6–10 inch section. The defect causes intermittent loss of camshaft signal, illumination of the check engine light, and inability to pass emissions. Repair requires cutting open the harness and splicing in new wire, costing approximately $700–$1,200 each time. This is a repeated electrical defect caused by poor harness routing and inadequate wire durability. This issue affects safety indirectly because the vehicle cannot reliably report camshaft position to the ECM, and the failure is unpredictable. The defect is widespread among vehicles using the same engine and harness design.

The 2017 Audi Q7 Prestige was purchased on November 7,2016. Since the purchase, all service was provided by one or the other of two Audi dealerships. During this period, the Audi recommended 10K, 20K,30K, 40K, 50K, 60K, 70K, and 80K mile services had all been performed. In the almost ten years that I owned the car, the oil and oil filter were changed 11 times at one or the other of the two dealerships. The mileage interval between oil changes was 6,383 miles on average with a maximum interval on 8,177 miles; the time interval between oil changes was 320 days on average with a maximum of 399 days. The engine oil cooler valve had shorted out internally and was replaced in April 2025 at 58,225 miles. By the end of August 2026, the car had travelled 71,375 miles. From 60,000 miles on, oil consumption has gradually increased to alarming levels:1-quart every 700 miles. On August 22, while driving at highway speed on the Pennsylvania turnpike near Pittsburgh, I experienced a sudden loss of power, rapid deceleration, rough running of the engine, and a “Drive System Malfunction “indicator. Fortunately, I was able to slow the vehicle and safely move off the highway. The car was towed ($396) to an Audi dealership. The technician reported that the diagnostic scan showed a misfire code for cylinder #2; and, upon inspection, the #2 spark plug was found to be excessively oil-fouled. When the technician swapped the coils and spark plugs from cylinders #2 and #3, the misfire remained on cylin

My 2017 Audi Q7 with the 3.0T engine has experienced repeated engine/ignition system failures. The vehicle displays a "System Malfunction" warning light accompanied by shaking and stalling. This same malfunction has occurred at least 3 separate times over the past few years. Each time, a repair shop diagnosed and replaced faulty ignition coils, and the vehicle ran normally for a period of time before the identical malfunction returned. The vehicle is currently inoperable due to the most recent occurrence. This creates a safety risk because the stalling and shaking can occur while driving, with no clear warning beyond the malfunction light appearing at the same time as the symptoms begin. A stall or loss of power while in motion, especially in traffic or on a highway, could lead to a collision. The problem has been confirmed and repaired multiple times by an independent European auto repair specialist, who stated this is a known, recurring issue with this engine/model. The vehicle has not yet been inspected by the manufacturer directly. Separately, the vehicle has also developed excessive oil consumption, requiring approximately 2 gallons of oil added roughly every 6 weeks, with the frequency increasing over the last 2 months. I am uncertain whether the oil consumption and the recurring coil/ignition failures share a common root cause, but both issues are ongoing and unresolved. The vehicle and its components are available for inspection upon request.

On my 2017 Audi Q7 with 93169 miles, I am getting the error message along with a warning lamp that states: "Front right side marker light defective." The light actually works however I am getting this message. If the light were to actually go out it would affect the safety of my vehicle. I hear this is a common issue with the 2017 Audi Q7s and is very costly to fix at the dealer because the entire headlight assembly is usually replaced by the dealer. My vehicle is available for inspection if needed.

Defective side‑marker LED inside sealed headlight assembly Component: Exterior Lighting / Headlights Make/Model/Year: 2017 Audi Q7 prestige Issue: Defective side‑marker LED inside sealed headlight assembly Complaint: The side‑marker LED inside the headlight assembly on my 2017 Audi Q7 has failed due to an internal LED driver defect. The LED module is sealed and non‑serviceable, so the entire headlight assembly must be replaced at a cost of $2,000–$5,000. The vehicle displays a “Side Marker Light Defective” warning even though the LED is still illuminated, indicating reduced output that triggers the fault. This failure reduces nighttime visibility and creates a safety hazard. This is a widespread issue reported by many Audi Q7 owners. Audi designed the LED module as a non‑replaceable component, leaving full headlight replacement as the only repair option. This is a design flaw that forces an extremely expensive repair for a basic safety function. I am requesting that NHTSA investigate this lighting defect.

Front right Marker light defect alert keeps pooping up and sounding an audible alarm while I am driving even through the marker light is working perfectly. Drive train alert comes on after I add oil and the vehicle starts hesitating while I accelerate.I just got a tune up which included new spark plus and a new coils. Problem came back even after the tune up within 3000 miles. Excessive oil loss. I constantly have to add a quart of oil even after I just got an oil change and tune up. Seeing oil in the cover shield that covers the entire engine. Seems like the oil is blowing out of the cap area where you add in oil. These problems are very costly for a vehicle that I ordinary love. Please advise what can be done because I can not pay for any more repairs out of pocket. There is only 80,100 mile on the vehicle.

Warning message on dashboard regarding right side marker light defective. This warning only occurs after sundown when the daylight sensor has engaged. Confirmed by Audi dealer service on 3/12/2026. Dealer reports this is due to a problem with a LED light inside the headlamp component. Dealer denies coverage for the repair under my active extended warranty. Dealer states an approximate $5,000 repair, at my expense, to replace the entire right headlamp assembly is the sole remedy. It appears the failed component may fall under the scope of safety recall, Audi 97CB (found on your website at: NHTSA ID 16V642-5761.pdf) but my VIN number is not specifically included within the recall. As this appears to be the same or directly related issue, perhaps the recall affects a greater amount of vehicles beyond the initially declared VIN number. My safety concern is that any problem with nighttime lighting is a deadly serious matter.

On Thursday, October 30, 2025, when I got seated in my car, put my seat belts on, and put the car in reverse gear to slowly get out of my parking space, it kept on going in reverse and won’t stop with break I tried to change the parking mode or drive mode but the steering column would not take any command. After 350 feet driven in reverse, it went into a ditch where it tried to turn it and the car was still in reverse, climbing out of the ditch, damaging another section of the fence, till I could turn off the engine with the ignition switch. It looks that the gear was stuck in reverse and after engine cut off it went back in drive mode. In the meantime, all four sides of the car were damaged and scratched all over, and there was damage on the bottom. Apparently it is electronic malfunction when the gear got stuck in reverse. Thank God that I was not in a busy parking lot, otherwise would have damaged dozens of cars and hurt many innocent bystanders. Will keep you posted till the Audi repair shop gives me a diagnosis

I am submitting this complaint regarding a serious safety issue I experienced with my vehicle. Shortly after starting to drive, about 2 miles from my home, while traveling at approximately 25 mph, the vehicle suddenly began to shake violently and came to a complete stop at the intersection of Crescent Street and Astoria Boulevard. At that moment, I lost all control over the steering wheel—it completely locked up. The dashboard displayed the message: “Drive System Malfunction – Contact Service.” These diagnostic trouble codes (DTCs) appeared: •P2179 •P025C •P0087 •P0306 This incident posed a major safety risk, as I was unable to steer or move the vehicle in a high-traffic area. I am very concerned that this could happen again or to other drivers under more dangerous conditions. Please investigate this matter as it may indicate a serious defect that could affect others.

My 2017 Audi Q7 Prestige 3.0T 6Cyl GAS CREC Supercharged has experienced repeated, serious failures involving the engine, powertrain, and fuel system. - At 72,000 miles, the vehicle developed coolant leaks under the supercharger, a failed water pump, and soaked drive belts. Repairs included multiple hoses, gaskets, and thermostat replacement. -Shortly after, repeated PCV/Oil system failures caused oil leaks, warning lights, and engine shaking. Repairs included PCV system, oil separator, valve cover gasket, breather pipes, and new spark plugs. - at 111,000 miles, the low-pressure fuel pump and relay failed, causing the vehicle to stall and lose all power while driving- a major safety risk. -Most recently, the engine developed a severe misfire in cylinder #4. Compression testing confirmed abnormally low compression (15 psi) due to a suspected cracked valve seat. The vehicle cannot be repaired without a complete engine replacement, quoted at ~$20,000. Safety Impact: - Vehicle has stalled suddenly in traffic due to fuel and engine failures, risking crash or injury. - Coolant and oil leaks present a potential fire hazard. - Loss of power and shaking while driving put my family and others at risk.

About two years ago I was driving down my recently paved street, and a loud bang shocked me. I thought something had hit my car. It ended up both of my rear suspension coil springs failed. I do not have a boat or trailer and have not put undue stress on it. Last week, while driving down a smooth street there was another loud bang, and my wife though I hit something, but no, I knew the noise. The front driver side suspension coil spring failed. I was 80 miles from a dealer and had to get it towed to a chevy dealer, with a repair cost of $3,000, and had to repair other parts of the suspension that were damaged. I also elected to replace the fourth and final one while they were in there so it would not happen again. Never in 40 years of owning cars have coils ever failed on me. There must have been a bad run, and this should be investigated. Suspension failure, if it happend at speed could have been dangerous.
