Car has been intermittently shutting down while driving. And starting up the car has become more and more randomly justified. Some times it starts up right away, some times it just takes a few cranks. Doesn't matter if it's warm or cold engine. I pulled ecu code and it says u0100 which is loss of communication to ECM. Well this is a safety issue because I can be driving just fine on the road but all of a sudden it just decides to quit cause a havoc on a busy traffic in houston.

This car has a massive oil consumption issue. A week after having an oil change the low oil light comes on after approximate 150 miles of driving. I started happening in february of 2017 shortly after the engine malfunction light came on . I took it to the dealership and after they ran the required tests that failed, was told that audi put the wrong engine in the car and that I would have to pay $8k for them to fix it. This is not my problem, it is audi's because it is the same issue that they settled in a lawsuit years prior. It is nerve-wracking to drive because, I never know how much oil is in the car.

Excessive oil consumption issues, check engine light is on and audi wants to charge me $12,000 to repair the oil consumption due to their being damage to my piston rings. I am the second owner of this car. During the time that the first owner had the vehicle there was a class action law suit that had been filed and settled against audi do to the manufacturer malfunction which caused the excessive oil consumption problems with the vehicle. By the time I became the owner the suite had already settled. At this point I don't know what to do.

2012 audi a4 has had ongoing oil consumption isuues. Audi dealer performed consumption test done around 74k (3qts per 1000miles - basically have had to add 1 qt every 300 miles. Was told no recourse - was outside of class action lawsuit of 2009-2011 of similar issues. Now at 133k mile, engine seized without warning - epc light came on - car was serviced less than 25k miles and had all 4 fuel injectors, 4 spark plugs and 2 ignition coils replaced and de-carb procedure done. I'm at a loss that audi refuses to accept responsibility for faulty engine.

We were just informed of a class action lawsuit involving timing chain and tensioner failure. This failure could cause catastrophic engine failure while driving and cause the vehicle to stop possibly at highway speeds causing an accident and harm to vehicle occupants. The lawsuit could result in an extended pro-rated warranty but no recall or repairs made to any vehicle prior to engine failure. Audi is aware of this problem and has issued a technical service bulletin to the dealer network but will not offer any repairs outside of the current warranty. We believe all affected vehicles should be recalled and repaired prior to a catastrophic engine failure resulting in loss of life.

Upon having 3 consecutive oil changes, my car suddenly began to burn oil (no leaks) after the first oil change upon driving less than 900 miles. Then the second oil change did the same thing upon driving under 300 miles. It actually ran out of oil totally. I added oil as instructed by the car, and it burn the oil withing 250 miles of driving. I took it to the dealer, who acknowledge that this model and year had the wrong engine put in the vehicle. They would need to replace the entire engine at my cost, with possible reimbursement to me. Not acceptable, since they acknowledged the defect. Oil continues to burn at a very high rate and potential cause additional engine problems while driving.
