This problem started happening about a month ago and occurs only once in a while and inconsistently. This makes it difficult to reproduce when trying to explain or show it to others. While driving, the car jerks as if I ran over something. It has happened about 5+ times and I have had others drive it to get their opinion. Its almost like the car slows down even if you're pressing the accelerator then suddenly jerks forward. My first thought is that it might be break or transmission related. Any idea what else this might be related to and what I might be looking at spending on repairs? Thanks in advance for you help.

Answers from the Automotive Experts

Judy Curry, Co-Founder and Vice President of Marketing at Currys Auto Service You did not state why kind of vehicle you are driving or how old it is. If it is a newer car with an electronic throttle it may require calibration (called adaptation) or it could be an issue with the transmission.

Laurie Sarno, Co-Owner at Super Girls Auto Hello Juliet- the first thing I would do is get it scanned for diagnostic codes- your local AutoZone can do a basic check for free- this could be a problem of engine management(Computer & Sensors), traction or stability control ( if so equipped), transmission if it is an automatic, the other thing you may want to check is with VW America - for recall or problem alerts also check TSB ( Technical Service Bulletins), as this problem may have happened enough to be reported to VW-the price for repairs is unknown until a proper diagnoses is made-Sorry I could not help you further, but intermittent problem are a nightmare. Thanks Super Girls Auto.

Suzanne Grego, Technician at City of Philadelphia Fleet Management Juliet, It would be really helpful if you could narrow this symptom down a little more. For instance, does this happen at low or high speeds? On a cold engine? Just after you've gased up? After you've been driving for a while? If this only when you are driving very slowly and you do not feel this is unsafe, I suggest you keep a record of when it occurs and what, if anything was done to the vehicle before this happens. If however, this is happening at high speeds or you just feel it is in any way unsafe, I would suggest you bring your vehicle in to your technician and have him/her drive it. It may take a couple of days to recreate the symptom and be able to diagnose it, but unfortunately, sometimes this is the only way to correctly repair a problem. Suzanne
