Audi A6 jerking problems

Filed Nov 12, 2021 · Driver assistance, Electrical · WY

Various components and system malfunctioned. Vehicle is in dealership for 3rd time on electrical/software/hardware troubles, SOS module. Yes, the vehicle is available for inspection. The car stopped me on a major highway thinking that I was not available "Emergency Assist, Driver take over the wheel" when I had both hands on the wheel, going straight and was fully in control of the vehicle. The car slowed down from 70 mph and the trailing truck behind me almost rear ended me. Yes, the problem has been confirmed by the dealer. The vehicle and components are being inspected/serviced at the Fort Collins Audi dealer. Yes, warning messages as well as the vehicle pumping on the break and jerking the seat belt. These started in Jun 2021 at 1400 miles and continued to the time I turned in the vehicle on 19 Oct 2021 at approx 13500 miles. I am attaching an 11 page documentation of dates, times and mileage of each incident that the vehicle's computer systems are not functioning properly and the safety features are not reliable or make the driver feel safe with bogus warnings, or warnings that are erroneous.

- Multiple computer/modules/safety features. YES, the vehicle is available for inspection - The Emergency Assist with Driver Not available came on and slowed my car down to the point I almost got rear ended by the truck that came up from behind - The problemS randomly occur and are intermittent, but I have accurate documentation of when they have occurred. The dealer has my Audi A6 now for the 3rd time with the same issues. They just told me that they saw a lane assist problem occur but did not give me details. - The vehicle is currently at the dealer for the 3rd time and they are talking with the manufacturer - Yes, plenty of warnings coming up and have started Jun 2021 at 1400 miles I have kept track of when my car has given erroneous or real issues over the last few weeks. When I bring the vehicle in today, 19 Oct 2021, it is the third time you will have it in for the same issues. The car is scaring me because the safety issues are not safe and it seems as if the sensors are not working properly and seeing things that are not there and activating without any concerns to do so. One of these times, the emergency assist came on when I was driving highway speeds and had both hands on the wheel going straight on a dry road and sunny skies (13 Oct), beeped at me 4-5 times with the message continuing to show on dash, the car jerked with the automatic brakes being pumped and no driver intervention as the seat belt was tightening on me, kept the emergency assist on to slow me down to the point that I almost got rear ended by the truck that was following me. I was driving normally/straight on a straight road within the lines with both hands on the wheel and there was NO reason for the emergency assist to come on. This is only one example of the car having a mind of it’s own when it is not warranted. I am afraid that the vehicle will CAUSE me to have an accident instead of protecting me from one. I have word doc of dates/times of incidents, too numerous to list.

The brakes are grabby and with a gentle depression of the brake pedal the car comes to a sudden jerky stop. Usually happens from slowing down from 10mph to 0mph the transmission jerks hard when speed drops from 15mph the engine erroneously shows check engine light during normal driving. Cylinders show oil leakage repeatedly. This has become a repeat issue and have asked the dealer / service center to report this as a manufacturing issue

When operating at low speeds the vehicle will sometimes unexpected lurch forward or backwards depending on if the transmission is in forward or reverse. I have automatic transmission. This often happens in maneuvers such as parking or backing into or out of a garage parking place. It happens when the transmission is in forward or reverse and typically when the driver's foot is on the brake and you are slowly easing into or out of a place like a parking spot or garage. This concerns me from a safety perspective since a prime time when this happens might be when I am pulling into or out of my garage at the beginning or end of a travel. My concern is that a child or adult may be crossing in front of or behind the car before it starts moving and then the car unexpected lurches forward or back and hits the pedestrian. It is almost as if the engine misfires and the engine and car "jumps" after the misfire. I have reported this to the dealership service department multiple times and they can not "reproduce" the incident. However, one of the service department personnel has the same model vehicle as me and says he knows what I am talking about because he has experienced it as well. It has happened on multiple occasions though I can not tell you any exact dates.

This has been the third time my audi a6 3.0t has been to the dealer since purchasing it as a cpo vehicle for a steering wheel jerk and squeak problem at any speed. It wants to move the steering wheel (since it is electronic) slightly as well as squeak. I believe there has been a recall notice for this problem but my dealer has yet to rectify this problem and many many others have this same issue. A simple google search brings up tons of owners with this issue. Please help me to bring this to audi and to resolution. I don't feel safe driving this car as it is currently.

At times when driving the car the acceleration becomes slow and it stalls with a jerk like it's going to just stop also, when the car is put in reverse gear it will not move. I am stuck. The prnd flashing on the dashboard. I become afraid because this can cause serious accidents.

1999 audi a6 quattro suddenly accelerated. I was pulling into a parking slot at maybe 5 MPH, my foot was lightly pressing on the brake pedal, as I was nearly in the parking stall. The engine was at idle speed. As I coasted into the parking stall with my foot on the brake pedal the engine suddenly and without any prior warning revved up to above 3000 RPM. The car lurched forward hitting the parking curb directly in front of me. I immediately applied more pressure to the brake pedal to keep the car from jumping over the curb, and shifted the gear selector into n. The engine then revved even higher, at which point I turned off the key. With the key off, I moved the gear selector to p, and restarted the engine. The vehicle then ran idled at normal speed, and drove normally to my home about 1/4 mile away. I'm afraid to drive the vehicle. This is the second time this has happened; the first time it happened was as I was coasting to a stop at a red traffic light. Again my foot was on the brake and the engine was returning to idle speed. As I approached the intersection the engine revved causing me to coast through the intersection before being able to bring the vehicle to a full stop, again by applying strong breaking force. I then put the transmission in n and the engine revved higher, so I switched off the key. Thankfully the other vehicles had already cleared the intersection and there was no collision. When I restarted the vehicle, it idled and drove as normal again. The outside temperature was above 45 degrees fahrenheit and the pavement was dry in both cases.

Sudden acceleration, caused by driver's loose floor mat. Started car in garage. In park, engine ran at 4,000 RPM from start. Tried to kick down gas pedal several times, no change. Ignition on and off three times, no change. Pressed firmly on the brake, shifted to reverse. I knew it would lurch. Got out of garage, pressing firmly. Rpms dropped to normal 1,000 range. Shifted into drive, car RPM increased to 4,000 RPM and lurched. Sat there for five minutes thinking it would settle down. Nothing. I then decided to check the floor mat. It was on top of the gas pedal. It had moved forward because the one of the securing locks on the mat had broken free

I have 3 major concerns regarding my 2002 audi a6 3.0 quattro. I will start with the most dangerous problem first...1) the anti-lock brakes that kick in unexpectedly. The ABS/esp problem started in may, 2007, with the ABS/esp light coming on intermittently, resulting in us replacing the brake light switch. The problem didn't happen again until the anti-lock brakes kicked in, in aug., 2009. With no definite, inexpensive fix from the dealer, we decided to see if the problem persisted. It did, bringing the car back in sept., 2009 & again in june, 2010. At this time, I had a private import garage replace the rotation rate sensor, which was what the dealer said the problem could be. The problem persisted further, with the light coming on every few months, until the brakes kicked in while going 60 MPH, making the car skid & jerk to a stop, pulling me off the road in late sept, 2010. It was absolutely terrifying! I had the car back to the dealer immediately, where they were unable to verify the concern. Since then, I have not had problems with it again until april, 2011, when the light starting coming back on at random moments & now yesterday, the anti-lock brakes kicked in while the cruise was set on 60 MPH. I am terrified to continue to drive this vehicle. I contacted audi of america in october 2010 with no help available! Now on to problem #2)the flooding in the interior floorboard causing the transmission module to have to be replaced. I spent thousands in oct, 2010 to fix problems caused by a water leak in the car. The dealer replaced the right rear window & door channels & seals, saying this was the problem. I found the floorboard wet again in march, 2011 & had to pay for the cracked pollen filter housing to be fixed. A little help from audi on that, but these well-documented problems with my car continue to be un-fixable. I've found complaints of these problems from others, am contacting a lawyer about my state's lemon law, & am so disappointed in audi!
