1 Power Train problem of the 2018 Audi A3

Failure Date: 05/01/2025

I was driving on the freeway at 60 mph when I received a warning code of a transmission problem. The code said the car was driveable but I should take it in for service. About 1-2 minutes after that the car lost all power. Unfortunately I broke down in the left lane in a construction zone without a shoulder. The state patrol had to temporarily shut down all three lanes of the highway to push me out of the traffic lane I was blocking. That was unsafe for me and for the state patrol and for the tow truck driver. The car was up to date on all recommended service, had been acting normally until the moment it failed, had not given me any warnings and is only 6 years old. I had the car towed to the dealer and the dealer reported that the mechatronic unit (transmission computer) failed. Replacing the mechatronic took a week and cost $5000.

7 Power Train problem of the 2018 Audi A3

Failure Date: 03/10/2024

About once per month my car will rev when the accelerator is pushed but the car will not proceed. On multiple occasions this has put the safety of myself and other road users at significant risk. This is because I'll be attempting to pull into traffic and the car will fail to proceed. This is a known issue documented by Audi in TSB #2060146/3 (https://static. Nhtsa. Gov/odi/tsbs/2023/mc-10232753-0001. Pdf). I've described the issue before to my dealership but only found out about the fix myself via researching on NHTSA's site. Further, this should clearly be a recall - the vehicle does not move when it is needed. Audi should not be charging customers for this update and it should be applied to all effected vehicles. Happy to provide any additional information needed.

8 Power Train problem of the 2023 Audi A3

Failure Date: 01/28/2024

My 2023 Audi A3 with less than 3,000 miles completely stopped in the middle of a highway in saugerties, new york. 4 hours away from home. I had my dog and my little sister with me and in the freezing pouring rain we had to get out and redirect traffic/ try to find help. I called roadside assistance. They never came on Sunday may 28th and didn't call back till 10pm to say they couldn't get to us because of the 8 inch snow storm. We had no heat because the car would not turn back on. 5 ubers/ 3 lyfts and all taxis didn't come. Finally 1 uber came and took us to a nearby camp site where they allowed pitbull dogs. The next day, I had to call over 60 times to get someone to just tow my car to Audi albany. Audi albany would not drive me a loaner car because it was an hour away. With a lot of arguing Audi roadside/tow services finally allowed me to drive with the tow truck driver to Audi albany. They gave me a loaner but said I had to book another hotel night because I was not allowed to drive the loaner back to my home yet. I was stuck in saugerties NY for 2 nights 3 days. We both got sick from Sunday waiting for roadside assistance for over 5 hours.

16 Power Train problem of the 2015 Audi A3

Failure Date: 07/15/2022

Consumer bought this car at 30,040 miles. The car currently sits with 89,000 miles. I have had 18 recommended service visits totaling $19,240 and then on July 15, 2022 with no pre indicators or warnings the engine dies after a 95k full multipoint inspection that consumer had 3 weeks prior. The car has an impeccable maintenace record. I did everything the dealer told me; and I still almost died on the 101 fwy going 70 mph on a conference call; the flashers didnt even work; the car dead and came to a hard halt and trucks were screeching around me with smoke coming from their tires because of the extreme hard stop and slamming on breaks, I was screaming for my life praying no one would slam into me. Metro who roams the fwy saved my life; without him I would be dead because of Audi's horribly manufatctured vehicle. It seems as though the dealer purposefully sabotages my car as a woman; I have no alternative but to fix it and now they want $27,000 more for a new engine and starter. So, in total; to drive 57,000 miles I've paid $37,000 cash for the car (I own the title)/ plus $19,240 in maintenance /repairs and now they want another 27,000 for the engine. I have no more money to give them. I recently returned my 3rd rental vehicle and I am out of funds on transportation. Ayudame ! how is this ethical? song and beverly consumer warranty act sect 1793. 2. (d) & (g). California health and safety codes 43204-43205. 5. Audis emission standards. California code of regulations sect 3396. 1-3399. 6. Cal code regs. Tit. 16 / 3396. 1. Thank you for reading this. Ps. I have every receipt and document; so if you need anything further I am so organized it's ridiculous; please don't hesitate to ask.

17 Power Train problem of the 2017 Audi A3

Failure Date: 06/01/2022

2017 Audi A3 etron sportsback- engine light turned on at 50k, when scanned for errors no codes. Then around 55k miles started to stall when slowing down or at a full stop. The car must be turned off then immediately go into drive. Felt very dangerous when driving in high traffic areas and areas with many stop lights/signs. Car error say transmission malfunction first then says something about limited power. We had changed atf and filter, still had issues. Then it started to not allow to go into reverse. Issues were intermittently happening then became more constant. Finally towed to Audi dealer they are not 100% but they say a new transmission is needed. After seeing complaints of similar situation I think this should be a recall on the transmission for these cars.

18 Power Train problem of the 2013 Audi A3

Failure Date: 04/29/2022

Car stalled in fast moving traffic, and then lurched forward. In the stall the car behind me almost ran into me. In the lurch, I almost rear ended someone. Fortunate that both times there was no collision. Took the vehicle to Audi and the car has been diagnosed with failed mechatronic - a $4,000 repair. It was shared that this is a known issue with Audi for my model year (faulty mechatronic), and as such has been recalled in several countries, but not the us. I called Audi USA and was informed that yes it is a known issue and has been recalled in other countries, but that NHTSA has not required Audi USA to open a recall here, and so they can't help me. I'm asking for some assistance. Thank you very much.

20 Power Train problem of the 2009 Audi A3

Failure Date: 10/22/2021

Dsg transmission will abruptly shift down to first gear and would not respond in any other gear. The shift indicator in the dashboard will light up and blink and the check engine light will come on. There are no warnings before this happens and it will happen at random times. It has happen in separate occasions while traveling at different speeds. When this happens while traveling it creates a dramatic reduction on vehicle speed almost causing the vehicle traveling behind me to rear end me. Once stopped the car will only engage when put on d and will stay at a low gear causing the rpms to red line even at low speeds making it unsafe to drive due to only being able to reach 5 to 10 mph. A scan was performed and codes p1814 press. Ctrl. Valve 1 open circuit/short implausible signal, and, p1835 press. Ctrl. Valve 5 short circuit to b+. This fault is random and there is no warning or indication of when it may happen making the vehicle unsafe at any speed.

22 Power Train problem of the 2015 Audi A3

Failure Date: 07/14/2021

The engine low oil light keeps coming on, the oil has been changed already, I’ve had the car for more than 7 months I haven’t even driven it over 5000 miles yet. Audi needs to fix this. The power train is also the same, some days it works okay and some days it doesn’t. The cars struggles sometimes to even reach speeds up to 50 mph. I’ve taken this vehicle to the Audi dealship as well as to a foreign certified mechanic shop. They can’t figure out the problem. The engine light should not be coming on randomly when I have fully serviced the vehicle. Audi please fix these problems.

23 Power Train problem of the 2017 Audi A3

Failure Date: 05/11/2021

“transmission malfunction/no reverse gear. Okay to continue driving” comes on constantly the past 2 years now. I’ve only had this vehicle 3 years. Yes , it is available for inspection. This puts my safety and the safety of my other passengers at risk because my vehicle will abruptly slow down in fast flowing traffic and it will uncontrollably accelerate when it’s time to come to complete stops. A local mechanic used a sensor to check for faulty defects and confirmed that my transmission is having sensor issues. There has never been any warning lamps , regarding this problem. There have been no prior warning messages regarding this issue. I purchased this vehicle from Audi dealership in van nuys, CA in November 2020. I have had this vehicle less than 3 years & as of now , it has less than 35,000 miles on it.

24 Power Train problem of the 2017 Audi A3

Failure Date: 01/10/2021

2017 Audi A3 sedan- with around 47,000 miles -stalled out in drive thru and at a red light intersection. Twice. Almost got in 2 accidents while driving once on the highway and once on a city road. Engine light on dash was blinking. Code reader initially was reading p0300, p0301 and p0302 . . Multiple cylinder misfires. Towed car to Audi, and they did complete maintenance service. Ran codes and now all of the sudden it need a new transmission and the code is p0172 bank 1 system too rich. I noticed there was a recall for the the engine control unit (ecu) software and which can affect air / fuel mixture which makes me think that this recall was probably the cause, because po172 code can be due to the air/ fuel mixture getting too far from factory specs. My car has been at the dealership for 6 weeks, the transmission was finally replaced by Audi but they are still saying that I need a new fuel canister (there was a recall for this in 2016, and my car was manufactured in 2016 but is a 2017 model) ? I have seen several other 2017 Audi A3 sedan owner complaints having this issue with very similar problem on this website and other websites. I was under warranty until 1/25/2021, but I live 2 hours away and I was under quarantine so booked appointment locally (I think on 1/22/2021 with Volkswagen but scheduling was a week out and on appointment date their entire service department was out because of covid outbreak by that time it was too late even though I have a time and date stamped video of the car having issues.

25 Power Train problem of the 2017 Audi A3

Failure Date: 09/01/2020

This concerns a recall issued. Audi issued a recall/reimbursement for transmission failure. Mine failed. Car stopped in the middle of roadway. I had transmission repaired before recall was issued. I have attempeted reimbursement and am denied by Audi due to my vehicle being a theft recovery. However they have performed multiple recalls on this vehicle since I have owned it with the theft recovery title. They also performed the transmission reprogram after I had it fixed at no charge. Nhsta itself states salvage/rebuilt title is no reason for not performing a recall except in exceptional circumstances when car is no longer drivable. I am asking for help in getting Audi to honor the recall. Had I been on the highway I would have been smashed when the car shut down.

29 Power Train problem of the 2015 Audi A3

Failure Date: 06/01/2019

Excessive oil consumption car has 2,300 miles left to the 10k oil service check change and showing low oil. This is not normal Audi is trying to say to just top off the oil, yet excessive oil consumption will cause the car to need engine replacement earlier than it should at about 70-80-100k miles at best. There are many complaints and a class action that involved this issue but they refuse to do more than change oil and check for leaks when they know it is due to defective parts and I am under a certified warranty until October 2019.

30 Power Train problem of the 2010 Audi A3

Failure Date: 10/10/2018

I have an Audi A3 manufactured in 2009 presenting severe issues with the abs control module. Audi has a recall for several Audi and vw models manufactured the same year, recall number 16v913000. Audi of America was notified however declined responsibility allegedly because my vehicle was not in the specified VIN range. Although my vehicle is presenting the same symptoms as those on the recall Audi is unwilling to accept responsibility. The experience was very unnerving as the car suddenly stopped while driving and suddenly accelerated. Fortunately the cars following behind were able to stop on time avoiding a serious accident. Aside from losing control of the vehicle, the steering loses position and the speedometer stops working. Furthermore the part needed for the repair has been superseded, this is very suspicious as to why there will be a new part number to replace the original if allegedly there's no problems with mine. . . ?.

34 Power Train problem of the 2016 Audi A3

Failure Date: 01/28/2018

Twice I have experienced the random loss of power. The first time occurred on a local street, driving approximately 40 mph, and all of a sudden the vehicle stuttered and lost power. It appeared as if the vehicle was slowing down, not even coasting but slowing down considerably. I was required to pull onto a side road. I restarted the car and the issue disappeared. The second time occurred on the highway driving in the left lane at approximately 70 mph. Same issue, car stuttered and then loss power. The car's speed slowed considerable fast, from 70 to 30 in apprximately 5-7 seconds. With the inability to accelerate on a three lane highway, it was difficult to make my way to the shoulder on the right side of the road. After the stutter, you can press the gas pedal and not acceleration is experienced. I did not notice any warning lights on the instrument panel. Brought the vehicle to Audi to address this issue, and their response was "we don't see any fault codes, therefore we have no record of it happening", and sent me off with a "good luck" vehicle had apprximately 12,000 miles and 15,000 miles when issues occurred. All dealer recommended maintanence was performed.

35 Power Train problem of the 2010 Audi A3

Failure Date: 08/29/2017

At slow speeds & when stopped with vehicle in gear (drive or revers) the transmission jerks, clunks, feels like it's engaging and disengaging. It is dangerous - especially when stopped or parking as the vehicle will suddenly lunge forward or backward depending on the gear you are in. Unfortunately it has only resulted in damage to my own vehicle - not to another vehicle or person.
