What 2014 Audi S4 owners say
Steering
The contact owns a 2014 Audi S4. The contact stated that while driving at 70 MPH, he observed multiple unknown warning lights illuminated. The EPC warning light was also illuminated. The contact stated that the "Do Not Drive" message was displayed. Additionally, the contact stated that the steering wheel was stiff and failed to steer as intended. The vehicle was taken to the dealer where it was diagnosed that the electronic steering module and rack needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 61,000.
2014 Audi S4 has dangerous steering behavior. The steering slips at the center position, will not go straight on the highway, and requires constant steering input. This is further exacerbated by a constant notchy feeling at any speed between the 10 and 2 oclock position. It is particularly bad in long sweeping turns where you can distinctly feel a notch. When in one of these turns you will have constant linear steering followed by a notch that when surpassed results in a large steering input which is unexpected and destabilizing to the vehicle if at high speeds. The problem is worse during cold temperatures. This is intermittent but repeatable and is a known issue on all 2013+ S4 & s5 models with the electric power steering. Audi should be required to come up with a permanent and safe solution as this is very dangerous. …
Transmission & drivetrain
My 2014 Audi S4 has a epc light that keeps turning on while driving that car. The epc light will put the car into limp mode and will have a rough idle and can barley drive. When that light turns on you have to pull over immediately and restart the car to continue driving and is a complete safety hazard because it will happen when you are on the freeway. The light mainly turns on when you are trying to get up to speeds of the flow of traffic. I have taken it to the dealer many times to get this issue resolved and they keep saying there is no issue with the car what's so ever. I decided to try to figure out what was wrong with the car myself because the dealer was no help. When I look it up hundreds of forums show up talking about it and no one can figure out what is going on with the car and everyone is having the same issue and how the dealer is no help at all. …
While traveling at 75mph, uphill, in 100f weather the fuel low pressure fuel system developed a vapor bubble that stalled the low pressure fuel pump and starved the motor for fuel. The car stalled on the freeway and would intermittently restart until the low pressure fuel pump failed. The repair required additional valves and hoses he added to the low pressure fuel system to compensate for the poor vapor management design. The car had to be towed to a dealership where the appropriate fix and TSB was executed. Total cost was ~$2200, $715 of that total cost were the new valves and hoses that should have been part of the initial design.
Fuel & propulsion system
I have encountered the problem of air bubble formation in my fuel system (code 16903) when reading codes in my car. I thought it was just a fuel pump issue so I replaced it. I then realized it wasn't just a pump issue as the car kept reading those codes and kept stopping. I talked to a local Audi dealership and said I would have to get the fuel pump vapor extension. When asked they said that it's only a TSB not a recall due to it not being a safety issue. Now you tell me, my car went into limp mode and stopped once in the middle of the highway, and 3 times in the middle of traffic 2 weeks later. I believe it's a safety problem as anyone could've ran into me and caused bigger problems. I don't think I should pay 800 dollars for my safety. That piece should've been included in the fuel pump assembly from the beginning. …
After 2 engine oil leaks, in 2.5 years, I smelled gas fumes in the cabin numerous times, scheduled an appt for a check with the west islip ny Audi dealership. Picked up car from dealership, with work order and service rep. Simply stating "no problem found" under each of my 5 concerns, which told me that they did not even look at the issues. With every work order, which are numerous on this car, it is stated what was done, but not this "service". Two days after picking up my vehicle, Audi reported a recall due to gas leaks in their vehicles. My vehicle is still under lease and warranty, yet this dealership took it upon themselves to ignore my concerns, which could potentially be fatal.? Absolutely no integrity, and lacking any sense of morals.
