Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Follow up to complaint 10852082. Once again my car lost all power including power steering, this time in the middle of multiple lanes of fast moving traffic. After the first two times, the defect was not identified by the dealer. This time, as I brought the car in right away, the computer detected that the issue was due to faulty camshaft position sensor circuits. They have been replaced and hopefully my car will now be fine. So here are the questions. Is this really what caused the vehicle to cease functioning three times" if so, how many of these faulty cps sensors are out there? it is just a fluke or do they wear out or is it a bad batch? should there be a sensor that will stop all power with no warning" this last incident happened on the entrance ramp to fort lauderdale airport where about 6 lanes of traffic comes around a curve and decelerates from 55mph to 25 as cars approach the terminals and parking. The speed limit is 45 going down to 15 but people are moving pretty fast. I wrestled the car over as other cars were struggling to avoid me. Once I had the car stopped, I removed the electronic key, reinserted and the car started back up fine.

Vehicle stalled out and started shaking only to find out injectors went out and oil consumption issues. Audi usa is prolonging an issue that they know is wrong with the vehicle regarding oil consumption. I have completed phase I of the test and took it to dealership to have phase II completed however without my consent or knowledge Audi has the dealership perform phase I over again. Car is eating excessive amount of oil but yet Audi usa is prolonging the situation with no resolution. Purchased the car 08/24/2015 had to have an oil change done two weeks later beginning of September by October 15th I had to add more oil as the oil indicator light came on come to find out there is a known issue for consuming oil. I have phase I completed however I took vehicle in to have phase II done on it only to be told they had to do phase I over which isn't fair the vehicle still eats oil and value is depreciating drastically because of Audi and Volkswagen epa violations.

I have a 2011 Audi A4 2.0T that continues to consume oil which lead to a major engine malfunction @ 25K; 26K & now @36K the engine seized on the highway nearly causing an accident on the highway as of 10/31/13 I have over a years worth of investigation notes about Audi's procedures to dealing with customers. Using myself as test subject to endure the misdirection and lies to perpetuate this cover-up there are over 1000 complaints documented for this oil consumption issue which can lead to your engine seizing up at high speeds. Audi of America refuses to handle this dangers defect in their Audi 2.0T engine because of the obvious cost associated with another recall for the Audi A4 model 2009-2012. Combined with the already court mandated recall of 2002-2006 Audi 1.8T engines. I have nearly been in three accidents from my car violently shaking to Audi most recently rushing to replace my complete engine at 36,000 miles to avoid a 15day clause in California to classify a vehicle as a lemon this car has been in the shop for more 46+ days due to the same issue as described in the service bulletin link below. I find it quite appauling that NHTSA has yet to force a recall for the american consumer. At 25,055 miles, on November 26, 2012, the Audi A4 began experiencing severe engine problems that caused the vehicle to violently shake coupled with a flashing check engine light and epc light. This left the vehicle in a debilitated state. After 4 days at the dealer, the dealer was unable to conclude the exact cause of the violent shaking but instead made what seemed like makeshift repairs to the cylinders, injection, and intake manifold. The saga continues for 1000 other consumers: & please review & help.
