On May 3, 2024, while driving to work, the vehicle acutely started to make a loud clicking noise in the engine compartment. I parked the vehicle and looked for a warning light indicator on the dashboard to determine the problem, but no indicator light emerged. I then called Audi Omaha and spoke with the Service Manager who kindly arranged to have my vehicle picked up and a loaner dropped off. I did ask at that time whether it was safe to have somebody drive my vehicle to Audi given the severity of the noise and I was told that since there was not a warning light on the dashboard, it would be ok. I later discovered that my vehicle stalled on the way to Audi Omaha and required a tow. On May 6, 2024, I received a report of the problem and the estimate for repairs. It was explained that the head of a spark plug had broken off into the engine causing the piston to make contact with the valve in cylinder 3 resulting in engine damage which was beyond repair. Additionally, a second spark plug had been misfiring for several days. The estimate to replace the engine: $9,282.03. To my surprise, the multi-point vehicle inspection report I received on the same day reported that everything (aside from rear brake pad wear) passed inspection -?" including the engine and spark plugs! On May 7, 2024, I called Audi Omaha to express my concern that an entire engine would need replaced on a 6-year old luxury vehicle with only 60,000 miles and spark plugs that were replaced at 40,000 miles prior to my purchase of the vehicle. Even more concerning is that no warning light indictor ever displayed on the dashboard (despite being informed that the vehicles computer system had detected changes in the engine compartment 2-days prior to this event). Because of these glaring safety concerns, this issue was escalated to the Audi central region division who declined to provide assistance despite the faulty spark plug and the malfunction of the warning indicator light.

The engine stopped working at 72,000 Miles. After the fact, I have read several complaints of the engine blowing well under 100,000 miles. Audi does NOT give warranties on engines after 50,000 miles...how convenient! In addition, Insurance will not cover this. I have read several complaints about engines blowing just after 50,000 miles. To have the 2018 Audi Q5 engine repaired with the new engine is $11,000 plus the labor $3,000-$4,000. Unfortunately, I still owe $19,000 to the bank! Bankruptcy is looming and I have had near-perfect credit my entire life.

On 8/8/2023 my vehicle was outside in the driveway of our home in Truro, MA. A large storm moved through the area with torrential rain and lightning. Once the rain let up I looked out the window to find all 4 windows down 4-6 inches, the rear hatch was opened with the rear wiper and high middle brake light on. When I ran outside to close the windows etc. I could not start the car the MMI did not come on and I could only get 3 of the windows up. I had to manually close the rear hatch. I put a tarp over the drivers side window that wouldn't close and had AAA come out. They assessed that it was not a battery issue bit an electrical module issue. I filed a claim with my Insurance and after waiting for the adjuster to look at the car I had AAA tow it to an Audi Dealership. They ran a diagnostic test on it and found water had caused the Comfort Module and associated wiring to fail. The estimate to fix the issues was is nearly $12,000. Because of the cost my insurance company is sending another adjuster out to inspect the issues at the dealership. There were no prior issues or symptoms before this issue took place.

My 2018 AUDI Q5 had the 5-year/50,000 mile factory recommended service in August 2022, the vehicle only hadwith 42,000 Miles and everything was perfect as it was the last year of the five year service extended contract. In July 2023 I was told the engine mounts needed to be replaced. Both mounts and vehicle has 53,000 miles. Basically mounts cannot the engine and transmission in place.This recommendation was done as part of the 60,000 mile recommended factory service based on my Google research. Many Audis have disorder failure which is which can be catastrophic because there are no warning lights for the engine mount failure when the car auto stops and starts it shakes. This has hung always been a standard, but annoying feature of the car, which cannot be turned off for emission purposes. Clearly the engine mounts cannot handle the auto start/stop of the vehicle. That-??s why it-??s failing for so many vehicles. It is frustrating given that the car is a $54,000 car and at 53,000 miles I run the risk of the engine falling on the ground, this information is widely available on the Internet easily accessible on Google. I ask that you please look into it. thank you for your time always. What is bizarre is that now when I accelerate hard, I can feel a little vibration of the engine before I didn-??t but that-??s something I cannot explain at the moment. The dealer that sold me the car brand new is the only dealership that has ever touched my car, and my car was always serviced as recommended once a year

My 2018 Audi Q5 has a water intrusion issue with control module damage. The vehicle reduce speed to 15 mph on the highway, when parked the lights would not shut off. The vehicle would then not turn on. Thirty minutes later the vehicle started. I received a front passenger seatbelt malfunction and several controls went out. The passenger seatbelt would not recognize there was a passenger buckled in the seat. The lights stayed on. The windshield wipers started on their own. The car wouldn-??t recognize the key fob. Later the turn signal malfunctioned, along with the front lights staying on but the rear light and license plate light would not come on. At the dealership they found water in the comfort module housing, left rear quarter panel/wheelbase and said it was probably caused by the pressure vent seal allowing water to enter damaging the comfort module and 56 wires. They stated the vehicle was unsafe and inoperable. They also were not able to roll the windows back up or lock and secure my vehicle. The issues with the vehicle speed occurred 5 weeks ago. The dealership changed the thermostat but the speed reduction happened again afterwards once but when it was turned off and turned back on the speed went back to normal. Then today the vehicle just went crazy with things turning on and other controls not working, like the taillights. Multiple times I have told the dealership of the seatbelt malfunction. They said it was probably the seat detecting something on the seat, like a bag but couldn-??t account for the malfunction when the seat was occupied. The vehicle is now at the dealership with plastic taped around the opened windows and unsecured since the locking controls will not work. They suggested I file a claim with my insurance for the repair. This screams defect to me!

Jan. 2023 my coolant pump had blockage which caused the coolant hose to break and discharge coolant all over my engine and overheat. I have the repair receipt from Audi Dealer and requested a copy of the inspection report from them. Pictures also attached. I also have my car at the Audi dealer as we speak due to a week later the car would not accelerate properly with a Drive System Malfunction error light, which is now the Turbo Charger needing replacement. Towed to Audi Dealer on 2.7.2023 and waiting for Turbo Charger delivery, currently on back-order. These are not normal wear and tear items on a vehicle with 53,000 miles.

On 02/14/2022. Car just died while waiting for cars to pass to turn at light. Dashboard started flasing "engine start system: malfunction! - Please contact service" then "Parking Break Malfunction!" then, "Steering: Malfunction! - You an can continue driving" Panicked because was holding up traffic. After a couple minutes trying Car then just started drove home and put on battery charger overnight. Hoping that's all it was. Next morning 02/15/2022 started right up early morning no issues to be concerned with was on highway doing approx 69 mph, drove approximately 42 miles then then while only driving 35 mph 4 lane highway. Again, No warnings, but while DRIVING Engine and steering, just shut down. Almost causing me to be reared and then hit on passanger side. I don't even want to think what could have happened had this happened on interstate or if my children were in the vehicle. It was a very dangerous and scary situation even happening while only doing 35 mph. This should be considered a MAJOR recall. Vehicle was towed on 02/16/22 to Clearwater Audi. We did not receive vehicle back until after over 9 weeks, 04/22/22. Yesterday, 06/07/2022 Sensors glitching again and being called back into dealership. I want this life threatening recall documented. There is absolutely no reason why a well cared for vehicle with less than 18,000 miles should be having these issues. We We keep losing out on time from work and driving back and forth to dealership. We need to be able to rely on the safety and integrity of this vehicle not only for the driver/passangers but for the safety of others on the road. Thank you for your time to hear our concerns

While driving down the expressway in Chicago, transmission, and all safety features completely shut off. Pressing on accelerator had no effect, and with limited steering was able to pull to roadside barely missing high-speed traffic. Expressway roadside is narrow, so was nearly hit by many cars while waiting for tow service. Car would not restart and with full electronic transmission, no ability to put into neutral. Audi roadside assistance did not provide timely tow service. Extremely dangerous and unsafe.
