ENGINE, ELECTRICAL SYSTEM
Car alarmed that my EV had a major electrical issue and made sirens outside as to warn others to not come close and keep distance as if the car will catch fire or explode. I replicated this warning again sitting in the car. Fearing the car will catch fire I had it moved out of my garage. My Audi Service Center was not able to replicate the issue and I provided video and photo evidence of the danger. They claim that car works normal. In the photo is the battery light and sos light on. In addition, all safety features failed to work. Audi Q4 Etron regularly crashes and driver lose federally required safety features. For example additional photos show the loss of speedometer reading stuck on 8 mph and other safety features. These crashes happen at least once a week.

ELECTRICAL SYSTEM
On 7/17/2024 at 11:39am at Bakersfield, CA.when weather temperature was in the 100s , when turn ignition on, lights on temperature control module (A/C, Heating) and emergency light switch started flashing unstoppable. I sent the video tu Audi of America and Audi of Bakersfield, CA. I got an email from Audi of America acknowledging the email was received. I’m afraid this is a dangerous electric issue that can start a fire. I have videos about this issue. Since I informed about this issue I still don’t get a solution from Audi.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, STEERING
I have noticed on my Audi Q4 in about 4 different occasions that when I applied the brakes in situations like when traffic suddenly stops, the car and wheels shakes in an uneven, irregular way. Like I never expected before in my more than 45 years driving BMW, Mitsubishi, Mazda. Besides that also always noticed that my car reduces the speed almost to stop suddenly when there is a car already moved into the right or left lane (lanes next to mine) such sudden slow down from 50 mph to 0mph causes the cars behind me to stop suddenly and in several occasions almost ending in a rear ended crash against my car. I guess the radar identifies the traffic ahead next to my lane as a traffic “in front” of my car. Also, even when I am holding the steering wheel with one or 2 hands, frequently I received a message on the dashboard asking me to “Please take over steering” in yellow color, and if I don’t move the steering wheel side to side the yellow warning turns into a Red warning on the dashboard saying “Please take over steering” and if I don’t steer side to side, I get several hard pulls on my seat belt and a load alarm. The only way to avoid such progress of “warnings” is by steering my steering wheel side to side (zigzagging) on my lane. Who ever see me doing that would think I’m drunk or distracted regaining control of my car.

STRUCTURE:BODY, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
In several occasions I have noticed my Audi Q4 windows and tailgate are open the next day in the morning in my garage, after I made sure all windows and doors are properly closed and locked, thank God hasn’t happened when parking in open public parking lots and or in raining days. Also many times after locking doors and applying brake properly (after double checking before getting out of my car) I receive on myAudi App the notification that “is not locked “, and after checking my car it’s “unlocked “. Sorry I don’t have pictures for this issue.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
As I was coasting into a parking space perpendicular to a curb, sidewalk, and store fronts, about a foot from the curb, the engine ROARED and rapidly accelerated. I removed my foot from the pedal and crashed into a pole supporting the canopy over the sidewalk. The impact was so great that the airbags deployed and the car bounced back onto the parking lot. Several lights on the dash illuminated while this happened and I definitely saw "Electrical Malfunction". The only way I could think to turn the engine off was to force the door open. My cat was in her hard sided carrier on the front passenger seat and the impact and air bags broke the carrier and she was ejected. Clearly the Pre-Sense Front collision warning/avoidance system did not function properly during this unintended acceleration. I am convinced that had there not been a sturdy pole directly in front of the parking space, the car would have continued to accelerate and crashed into the storefront of the restaurant directly ahead - and MANY people could have been injured or worse. The "Electrical Malfunction" light had illuminated several months earlier when starting up after being parked for a short time but when I drove the few miles home and turned it off, then on again, it did not illuminate so I forgot to report this to the dealership. This car had been returned to the dealer several times during the two years I have owned it for several recalls, an unresolved air conditioner warning light, and a "known" problem with the brakes getting locked up after getting wet.

VEHICLE SPEED CONTROL, SERVICE BRAKES, HYDRAULIC, STEERING
The contact owned a 2024 Audi Q4 E-tron. The contact stated upon driving into the parking lot of an occupied charging station at 30-35 MPH and attempting to pull into the charging station, the vehicle accelerated unintendedly and spun several times. The contact stated that she depressed the brake pedal and attempted to steer the vehicle, but the vehicle failed to respond. The contact pressed the Push to Start button to stop the vehicle, but the passenger's side of the vehicle hit and knocked down a small tree, crashed into an embankment, and the vehicle stopped. The air bags did not deploy. There was no warning light illuminated. The contact was able to exit the vehicle. There was no injury sustained. No police report was filed. The vehicle was towed to G & C Auto Body(3440 Stanley Blvd, Pleasanton, CA 94566) to be repaired. The dealer was notified of the failure and advised the contact to tow the vehicle to their location after the body repair because they would need to read the EDR to determine the cause of the failure. The vehicle was not repaired by G & C Auto Body and was deemed a total loss by the insurance company. The manufacturer was notified of the failure. The failure mileage was approximately 5,000.

SERVICE BRAKES, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
I was driving on the highway at a very slow speed (<5mph) due to heavy traffic. All of a sudden my car accelerated and hit the car in front of me twice because brakes would not apply. I found similar user reports online (links below). These cases suggest that my experience is not an isolated incident, which raises serious safety concerns.

ELECTRICAL SYSTEM
The trunk power liftgate is often falsely activated by the foot-activated sensor. Even when your feet are not moving, if they are anywhere near the sensor it can set it off. This causes the hatch to close on you when you're standing under it with no way to stop it. This happens suddenly with very little warning. You have very little time to get out from under the liftgate.

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY
My first two years of ownership of the Juicebox 40 were pretty uneventful. However, over the last few months my Juicebox 40 became very unpredictable. Sometimes it would charge outside of the Time of Use (TOU) settings I had defined in the Enel X way app. Sometimes it wouldn't charge during the times it was supposed to be charging. There were a lot of random error messages. My hypothesis was that the Juicebox was receiving contradictory commands from multiple sources at Enel X. The support staff at Enel X could not figure it out. Then, on 9/12/24, I walked into my garage and smelled smoke. I had a sense it was coming from where the Juicebox connects to the 14-50 wall plug so I cut the breaker. When I went back to investigate more closely, I saw that the Juicebox had completely melted the 14-50 wall outlet. The smell I was smelling was the 14-50 outlet completely melting down.

ELECTRICAL SYSTEM, ENGINE, STEERING
While moving downhill at approximately 20 mph, the car suddenly lost all power and went into park. This abrupt stop caused the safety belt to lock me into the seat. As a result, two cars following me were forced to take evasive action to avoid rear-ending me. This sequence of events repeated itself, culminating in a sudden lurch forward as if the pedal was fully pressed. I managed to get the car out of traffic and notified Audi that a tow was needed because driving was unsafe. The car is currently at Audi of Honolulu. This is not the first loss of power issue with this car. A few days after purchasing the car it lost power in my garage. No towing company could extract the car from the garage because of its height and width with the towing equipment. The car reset itself after four days, and it was towed to the dealership. This car poses an immediate and extreme risk to the driver, passengers, and the public. It is imperative that this issue is addressed without delay.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
While driving, the car lost power, stalled, and rolled backwards down an incline. Fortunately, the brakes worked allowing me to bring the car to a safe stop. The dealer has been trying to repair the car for 40 days (the repair is not complete). The repair included replacing the front motor. When I went online to the Audi forums, it appears many drivers have experienced the same problem. Some type of refrigerant leak causes a failure of the front electric motor which causes the car to lose drive power (stall). I can't tell from the online forums how prevalent (or rare) this problem is, but it is clear that I am not the only Audi Q4 owner who has experienced the same sequence of events.
