audi a4 2010 Complaints

POWER TRAIN:AUTOMATIC TRANSMISSION

the 2010 audi a4 2.0t which i leased lunges forward every time it is down shifted in triptronic mode (manually shifting the automatic transmission). today, i reported the defect to the service writer scott summerfield at mcdonald audi in littleton co and he told me he was aware of it and that he thought audi might be working on a "fix" for it. i think you should compel audi to replace the transmissions because the lunging is a potentially life threatening defect. the manual shifting mode of the automatic transmission is used mainly on unsafe steep mountain roads to avoid riding the brake on a downhill grade and to acquire greater control of the vehicle on slippery terrain where the possibility of a fatal accident such as going over a cliff is great.

damage to secondary radiator caused coolant leak. secondary radiator is not sufficiently shielded or protected from debris. there was no visible debris on the road leading me to believe something as massless as a large bug could have caused the damage. car was towed to dealer and repaired.

POWER TRAIN:AUTOMATIC TRANSMISSION

i have a 2010 audi a4 with the "multitronic" cvt transmission. when the vehicle is on an incline, the car rolls-back (or forward) when in drive, much like a car with a manual transmission. i have taken the car in for service and was told that this behavior is "normal" and functioning "as designed." while this has not caused an accident, this sort of behavior has the potential to cause collisions with the car behind (or in front) when on an incline, grade, hill, parking garage, parking lot, etc. this behavior has cause frightening situations in which i've had to slam on the brakes for fear of hitting the car behind (or in front) of me. this has also caused the driver of the other vehicle to honk in fear of getting hit. i have not observed similar behavior in vehicles with traditional manual or automatic transmissions. this behavior seems to be limited to audis with cvt transmissions. i have been able to reproduce the same behavior on a friend's 2009 audi a4 with the same transmission.

ENGINE AND ENGINE COOLING

there is a foul odor from the heat/ac vents after only 4 months of use. the car is clean from head to toe so i couldn't figure out what could have caused the smell. i took it in to be serviced and they preformed a tsb to remove the odor. it then smelled like a musky lemon. a month later the foul odor is back, not sure what is causing it but not very pleased with the brand new funk aroma. i'm going to have to take it back in again.

car brought in for misfire condition that resulted in power reduction/hesitation while driving. dealer detected faulty injector. replaced injector and engine was still malfunctioning. dealer then removed cylinder and observed piston ringland damage. vehicle was starting to exhibit excessive oil consumption problems. either faulty injector or piston ring defect is suspected to cause damage. looking into remedies through arbitration or other means as audi is aware about (i.e. undersized rings / pistons). i will retain all suspect parts as audi will not honor under warranty terms and independent shop will be performing repairs, and can be made available for further investigation. excessive oil consumption is a known issue with audi usa. the manual states that normal consumption is up to 1 quart for every 1000 miles. per audi's recommendations, you will burn 10 quarts of oil before you need an oil change. that engine holds 5 quarts when not leaking it through rings, reducing anti-knock rating of fuel during combustion. i believe this a significant safety hazard as engine seizing could unexpectedly occur due to defective components. i believe a class action lawsuit is inevitable.

during an attempt to accelerate the gas pedal was pushed to the floor (audi a4 '10) and remained stuck to the floor even after the foot was removed. the car has a manual transmission and was shifted into neutral at this time. the tachometer indicated the engine was redlining in neutral while the foot was still off the accelerator pedal. this engine speed lasted for approximately 5 seconds then the accelerator appeared to become unstuck and car operation returned to normal. an aftermarket floor mat was in place at the time of the incident. however, the mat was "zip tied" back to the driver's seat mount so it would not shift forward and possibly interfere in clutch, brake or accelerator operation. after this incident, the same day, the driver checked to make sure the floor mat was properly placed and still zip tied and it was. the floor mat was zip tied to begin with because there was one other episode of unintended acceleration approximately 1 year ago that the driver though may have been due to slippage of the floor mat. obviously this initial event a year ago could have been due to causes other than the floor mat.

bought the car used from a dealership that inspected the car for any defects. while test driving the car, i had to return the car to the dealership for repairs. the cars fuel pump was failing and causing excessive misfires. then about two months after driving the car, it began to use oil excessively. i checked for any leaks and found none. i contacted the dealership and was informed that anything less than 1qt per 1000 miles was considered normal under audi standards. personally i don't agree! now approximately 20000 miles later and 8 months, it burns a qt of oil every 300 miles. i know this is excessive as i can now see and smell oil from the exhaust. i contacted audi for a resolution since there are numerous complaints about the excessive oil but as expected, since i did not buy the vehicle from an authorized reseller, it couldn't be covered. if the engineers at audi know some of the cars produced with the 2.0 turbo engine were assembled with pistons and rings that were too small, why hasn't a mass recall been issued to resolve the issue? i would like this issue to be resolved before something more catastrophic occurs.

the oil was changed at 70,000 miles. the oil light came on twice after less than 2,000 miles. i added oil the first time, and it's on again after less than a week. i checked a few forums on line and other owners have experienced the same thing. the car is not leaking oil, so i'm figuring the engine must be burning oil. a few mechanics i've spoken to have said that some audi a4's have been recalled for this problem.

i bought car used from an audi dealer, and months later the car rattled and the whole car was shaking when i turned it on in the morning. i turned it off and on again, this stopped the problem. i thought it was probably the weather of around 53 degrees f. months later it did it again two more times but this time the weather was not cold and i drove an hour earlier. in january of this year, i drove 40 miles and when pulling into my driveway the car turned off on its own. i could not possibly turned it off due to both of my hands were on the steering wheel as i was turning into my driveway. thanks god i was driving slow because my kids were outside. i checked the key and it was still pushed down. my husband that was also outside noticed what happened, he told me to take the car to the dealer. i had already taken this vehicle for making noise when turning. i took the car to the dealer for the car turning off. once the dealer was done troubleshooting they say that there's nothing wrong with the car. they could not duplicate the problem. i still have this problem of the engine sometimes shaking the whole car when turning on. and as for my steering i still have the problem, i paid for new tires, alignment, and for tire balance. i really don't have time to keep taking the car to the dealer for them to say that they could not duplicate the problem.
