2018 Audi Q5

I got a Safety System Malfunction! Fault. I took it to aan Audi dealer and they said it was an issue with a harness under the passenger seat. Tech notes here references a service bulletin. Air Bag Occupant Sensor - Replace | faults present b1225f1 - tsb 2051242/7 -- per tsb apply wiring ties to secure and prevent faults from returning -- not covered under extended warranty policy. Not sure why this isn’t covered under extended warranty or a recall. It basically disables the passenger airbag. I have seen other Audi vehicles with recalls for similar issues with harness under the passenger seat. I think they have a design issue but are wanting to charge me (and probably others) $220 to diagnose and $695 plus tax to put two wire ties on the harness to supposedly fix (or bandaid) a bad harness.

-Car shut down (engine off, battery still functioning) while driving. Car went into neutral. -Lost power steering and other functions after about 20 seconds of the engine shutting down. -Immediate life-threatening danger while driving to us and surrounding drivers and pedestrians -no inspection or police report yet. -the car has not been driven since the incident and so the problem has not been reproduced yet. Upon inspection of the trunk area (2018 Audi Q5), we found about 4 inches of water. This has been attributed to clogged sunroof drains causing water to flow into the trunk and short out electrical components.

The contact owns a 2018 Audi Q5. The contact stated the vehicle was parked during a rainstorm and the contact attempted to start the vehicle, but the vehicle failed to start. The vehicle was taken to the dealer who performed a diagnostic test and stated that water entered the vehicle through a fractured seal causing the electrical wiring to get wet. The vehicle was not repaired due to the cost. The contact referenced NHTSA Campaign Number: 21V947000 (Electrical System, Structure) as a possible solution to the failure however, the VIN was not included in the recall. The manufacturer was notified of the failure. The failure mileage was approximately 190,000.

For months the car has smelled musty. Last week the electrical lights went on and warnings to not drive the car. Water was discovered in the wheel wells and the computer system appears to have been damaged by a leaky sunroof. On the car fax report it was noted that at 14, 608 miles the vehicle had it's sunroof "replaced/ repaired" with a seal removed and repaired according to an invoice record furnished to us by the dealer . The vehicle ran out of it's warranty in July of this year. We've heard that others have been having a similar, if not the same issue and the dealership has quoted up to $20K to repair. Clearly there has been a defect from day one at 14,000 miles. The car is never parked under trees.

The car was sitting in the driveway in the rain. I went out to get something out of it and the car was dead, but the back wiper was going, the rear lights were on and the driver side windows went down. I had it towed to the dealer and they told me water had gotten into the area in the back left wheel well where the comfort module is located. The dealer tried to say there was something wrong with the rear hatch but there isn’t. I’ve read account after account online of this exact issue happening to other owners and it caused by a defective sunroof drain. It drains right into the rear hatch with the module. They quoted $9000 for the repairs.

Rear Sunroof drain leak into major electronic components. 2018 Q5 with 61k miles after heavy rain started receiving all kind all errors including lights and ignition. Upon inspection Audi service has stated that HVAC control module has shorten (the area with the module in the left rear portion of the trunk filled with water), quoting repair of the module and insisting to replace sunroof drain hoses for total of $5k. Insurance has agreed to cover module replacement due to the flood of approx. $2,5k, however drain hoses and deducible with another $2,5k would not be covered and is on me. Mechanic in the Audi service several times noted that that this is common issue with Q5 and Q7s., I am so frustrated and do not understand how come the Audi car the owner shall be responsible for any cost of such if it is unclear: 1. How and why the water gets there through the closed sunroof in such amount to flood electrical equipment. Are all Audi sunroof seals so bad that they fail in 6 years? 2. I had serviced the car in the Audi for up to 60k, and no one ever cleaned the drains there or advised me of such (all is needed a small note for me)? Why did I pay extra to service car in the official dealerships? 3. How Audi could sell a vehicle with such design flaw, placing weak drainage hose through the electrical equipment compartment, considering they just had a class action lawsuit over sunroof leaking but on different models and model years.

The contact owns a 2018 Audi Q5. The contact stated that vehicle failed to start. The contact stated that while replacing the battery, he observed condensation near the wiring. The vehicle was taken to an independent mechanic where the vehicle was hoisted up and there was condensation draining from the driver’s side of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 48,000.

Suddenly car entry stopped working. Warning messages on display about start/stop, engine starting malfunction, every single light. I found the driver rear side full of water where the fuse panel and control modules are located. There was water soaked into the insulation at the bottom of the space as well as the insulation over the wheel well. Water drops were viewed on the controllers in that space.

Comfort Control Module (J393) is malfunctioning due to water getting into the wiring components and surrounding areas. The rear lighting stops working all together; No taillights, no brake lights, no turn signals, no license plate lights, and no lights when backing up. The problem has been reproduced by an authorized dealer. The component was removed by the dealer and noted of water inside the module and corrosion on the pins/ internals because of the water. The warning lamps occurred at the same time the lights stopped working. There was never any "prior to" warning. The warnings disappear randomly, no set time until they cleared. I am assuming once the module dries out over time is when the warnings start to clear but that is just speculation. UNKNOWN cause of the incident, but water is getting into the inside of the car somehow.
