1) Electronic emergency brake goes on repeatedly when attempting to put vehicle in gear. 2) Speed control has coasted to a very low speed while on the highway several times, on its own with no vehicles in front of me. 3) Numerous other "glitchy" electrical issues exist. Dealer says they are collaborating with engineers in Germany. There is currently no fix. It is as if the vehicle is always cycling through various "glitches".

Latest A3 acceleration complaints
While driving on highway 59 my vehicle began to jerk. I tried to accelerate and the vehicle would ramp but not move fast. My check engine light came on as well as the error code "transmission malfunction you continue to drive until engine is off." After getting out of Houston, Texas rush hour traffic, I had my vehicle towed to a mechanic. The mechanic ran several tests and checked the engine. Upon diagnosing the vehicle, the scan tools gave a myriad of fault code relating to electrical valve faults. All of which...

clear when driving the vehicle again. The mechanic informed me the transmission was not the issue but the mechatronic system had failed due to a faulty part. The mechanic said the issue could be repaired but would likely occur again as Audi as a history of faulty mechatronic systems. The mechanic called an Audi dealership who stated Audi's mechatronic control unite has not yet resolved the root cause failure at factory level, meaning all replacements and repair kit components still have the underlying defects that will cause malfunction, usually outside the short one-year manufacturer warranty. I believe Audi manufacturer knows their cars still have a defective part hence why an extended warranty on the mechatronic system is offered. Also, Audi vehicles made in 2016 were recalled due to a defective mechatronic system. My vehicle was made in early 2017. I called the Audi dealership to make them aware of the safety and they ignored me, and tried to sell me another vehicle. This is my second safety issue with Audi vehicles, the first being an expulsion safety issue. There is no way I am purchasing another Audi.

accident. A police report was not filed. The vehicle was towed to an independent tow yard where it remained in their possession. The contact also stated that the ECM module was defective and would not properly track her vehicle's mileage. Prior to the accident, the contact had taken the vehicle to a dealer where they offered no assistance for the repair. The manufacturer was notified of the failure prior to the accident and was offered no assistance. The vehicle had yet to be repaired. The failure mileage was approximately 3,000.
Tl* the contact called on behalf of her husband who owns a 2015 audi a3. The vehicle was purchased in march of 2019. While the contact's husband was attempting to park the vehicle, he depressed the brake pedal and attempted to reverse the vehicle closer to the curb. When the driver shifted into drive and released the brake pedal, the vehicle independently accelerated and the steering wheel seized. It took the driver excessive strength to turn the steering wheel. The vehicle continued to accelerate on its own and...

came to a stop when it crashed into the neighbor's parked and unoccupied vehicle. A police report was not filed. The contact stated that the driver was in shock. The day before the crash, the radio stations independently mixed up on their own and there was a lot of static. An unknown dealer was called and notified of the failure. The contact planned to take the vehicle to a dealer the following day. An appointment was scheduled with the manufacturer to have someone inspect the vehicle. There were no injuries. The vehicle was not towed and was able to be driven. The vehicle was not diagnosed or repaired. The approximate failure mileage was 36,000.
Car stalled when driving on highway! Would not restart. Broken cam chain!!!!! Very expensive repair at this point!!!!!
I bought a cpo 2016 a3 1.8T from audi of palo alto on may 20, 2017 with a little under 19100 miles. Great fast car. Until june 17, 2017 when it had 19878 miles. The car started to stutter/sputter/jerk while on the fwy. I was going about 50-60mph on the fwy, cruising, and then it stuttered. It lost the power to accelerate to keep up the fwy pace and it slowed down considerably so I pulled over. I had it towed to the nearest dealer (audi of concord). It was there from 6/17 to 6/29. Dealer said it had a faulty turbo,...

stating the wastegate failed, so they replaced the entire turbo. I got the car back with about 20072 miles, so apparently they did some road tests. Yesterday, july 3, 2017, while picking up some gifts for my daughter's birthday, the issue came back again. This time, my wife and 2 small children were in the car. We were cruising around 60-65 mph. It was scarier as I had to think for their safety first and foremost. Imagine a car that suddenly lost acceleration power on the freeway at around 6:30pm. We easily could have gotten rear-ended. Anyway, I researched on audi's reliability and did read on some comments about how lousy they are. I gambled and decided to buy one anyway. Boy did I lose big. At this point, I'd rather have a kia or chevy.
Tl* the contact owned a 2009 audi a3. The contact stated that while driving at 25 mph, the abs and the esc warning lights flickered. As a result, the brake pedal and accelerator pedal failed to engage and caused the contact to crash into a tree. The air bags failed to deploy. The driver sustained a mild concussion and body bruising that did not require medical attention. A police report was filed. The vehicle was towed and deemed destroyed. The manufacturer was notified of the failure and the vin was included in nhtsa campaign number: 16v913000 (service brakes, hydraulic, electronic stability control). The failure mileage was 87,000.
2013 Audi a3 tdi., Serviced for 65k maintenance 10/31/15. Next day , the car began abruptly loosing forward momentum under acceleration, and died in an intersection. Towed to audi, and they told me it was bad diesel. They flushed the diesel and replaced the fuel pump. (Kroger denied my bad diesel claim.) On 11/2/15, the check engine light came on, same issues. Dealer told me it was the engine speed sensor and replaced it. One month later, 11/6/15, my check engine light came on again, with the glow plug light...

flashing. This time the dealer said it is was throttle sensor fault. They had to order the part, and told me it was 'safe to drive'. In the time between, I would regularly experience the loss of forward momentum while accelerating up hills. I had the work done 1/7/16. 9 Days later after the throttle sensor replacement, saturday, 1/16/16, while I was driving, the car began unexpectedly losing acceleration in an extreme fashion, and stalled out twice within a 15 minute drive. It had been suddenly and briefly losing acceleration when accelerating while going uphill for several days. It also stalled out while accelerating into an intersection (extremely dangerous) and while parking. I had an error # p2101, and it would not accelerate past 40 mph while going uphill until I stopped and restarted the car. On 1/18 (monday) I took my car into audi service. They have had it until now, 2/9/16, and have replaced the entire computer, and it has not fixed the issue. They were able to replicate the issue, but have not been able to find a solution. They now say that they recommend replacing the engine wiring harness. This is a concerning safety issue, given the abrupt drop in acceleration going uphill, the loss of acceleration and the multiple stalls while driving.
3 Issues: 1. After initial start-up, the car jumps gears and jolts forward for the first 3-5 minutes of operation, especially at lower speeds. This has been consistent since the car was purchased brand new in january 2015. 2. Also, at higher speeds (65-85mph), the car shakes noticeably - the wheels/tires have been rotated and realigned multiple times but mechanics have said it is an internal transmission issue. 3. Lastly, the tpms will come on every month and need resetting despite tire pressure being intact.
I was driving along the ny state thruway in albany at 65-70 miles an hour. I realized I was unable to accelerate and saw that the glow plug light was flashing. I slowed down and tried to move over to the right, but as I slowed, the car stalled and I was in the middle lane. I was in the middle lane with cars passing me on either side and I was unable to restart my car. It was so scary. I couldn't get out, I was alone. I didn't know what to do, I felt my life was in danger, unable to get out of my car. I got myself...

together enough to call aaa. They called the police to help me with traffic. I was pushed to the side of the road dodging cars and trying not to get hit. Aaa came 1 hour later; it was 12:00pm, hot and humid on the labor day holiday! They towed me to the nearest audi dealer which was 20 miles away. I had to pay for the extra miles. I am 3 hours from home with no idea what I am going to do. My daughter had to come pick me up and drive me back home. Now my car is in albany and I am in massachusetts. I don't know what is wrong with my car or how I am going to get my car back. This was a very scary, unacceptable incident! *Tr
After the vehicle came to a stop at a stop sign, and I tried to get the vehicle to move again, its response was very weak as if it had lost power. Couple of times earlier, the vehicle refused to engage into reverse gear, stranding me in a parking lot for a while. On showing the dealer, the fault was in the mechtronics unit of the dsg (direct shift gearbox). Audi has recalled cars from year 2007 onwards for this issue, claiming that 2006 and before are not affected. This is not the case as it has happened with my...

car, which is a 2006. The symptoms and failed unit are exactly the same, with the same resolution proposed by the dealer as they would for 2007 year onward models. At the time of writing this complaint, audi has refused responsibility and are not supporting the recall for my vehicle. I think this is serious oversight that audi is unwilling to accept responsibility for and should be corrected by nhtsa's help. The exact symptoms are also mentioned in this news article http://www.Autoinsane.Com/2009/08/28/news/recalls-tsbs/volkswagen-recalls-53300-new-vehicles-announces-service-program-to-address-dsg-complaints/
On my way to work in my 2007 audi a3-all of a sudden I lose power and my car stops accelerating and shifts into neutral. I see that the p d n s lights are flashing so I attempt to restart my car. It starts to go again and then sputters forward without me doing anything. Luckily I wasn't far from home and was able to restart my car again and get it home while the car revved like crazy going less than 20mph. After some research I have found that many audi/vw's experience this in their vehicles. These are all characteristic of a faulty mechatronic unit associated with the car's dsg. *Tr
High pressure fuel pump defective. Car will not move when gas pedal is applied. Vehicle also does not accelerate at times when merging with traffic because of lack of combustion in engine. Have had close calls when crossing lanes of traffic because of this. Many times there is a 2-3 second delay before acceleration occurs. *Tr
Tl*the contact owns 2008 audi a3. While driving approximately 30 mph on normal conditions the vehicle stalled without warning. The engine restarted and resumed operation. In addition, on a separate occasion the vehicle exhibited an unintended increase in acceleration. The failures occurred intermittently. The vehicle was taken to an authorized dealer for diagnostic testing on three occasions for the identical failures. The technician was unable to duplicate the failures. The vehicle has not been repaired for the malfunctions. The failure mileage was 7,000.
