Even after having the fuel system replaced due to recall, I’m still smelling gas inside of my car. My EPC light and Check Engine light keep coming on and don’t always stay on but when it comes on, while driving… my car will tell me to downshift and then there is no throttle, you can mash the gas pedal to the floor and only dash lights. It has also skipped the downshift indicator and just cut completely off while driving.

We purchased the car in May 2021, within a week, the check engine light, EPC and oil lamp became illuminated. Contacted dealership who "inspected" it and said "nothing was wrong and reset the lights." A few weeks go by and the same thing. We noticed the car was "stuttering" during acceleration. We attempted to bring it to the dealership they couldn't inspect our vehicle because they didn't have "availability". My husband brought it to a local mechanic who recommended bringing it to the dealership again because of the codes it was throwing. We scheduled an appt which was 4 months out. During that time the oil was changed every 1.5 months because the lights kept coming on. Moved to Mississippi and the issues became worse. The vehicle would seem to lose power while driving on the interstate causing a Semi to veer into the other lane because the car went from 70mph to 20mph in a matter of seconds. Brought it to VW of South MS, was told Timing case, sealant, rail, tensioner, gasket, and several other things were needed to be replaced. Was told the vehicle was burning oil, lower timing cover was replaced and found bolts from tensioner broken and metal shavings. Was charged over $2500. 1 week later same exact issues occurred again. Brought it in, reset lights told us "it's fine" Few weeks of the car not being driven, happens again. We bring it back and they inform us of an array of "new issues" charges us $2000 and within a week the car is back for the same exact issue. I reviewed the recalls but it is saying none of them apply to my vehicle but they are the exact things that are going on. It is unsafe to drive the car. My husband will not allow me to drive it out of fear that it will stall and result in a serious MVA. Why isn't VW doing anything about this issue? How many people have to get injured or killed for them to conduct an investigation for this issue?

- Evap System, it is available for inspection upon request. - The check engine light will not turn off because of electrical wiring due to a faulty connection with the Evap system. It has been checked and there are no leaks and I have been told by three locations that it is a electrical wiring issue. Since the check engine light will not turn off I can not be notified if there are other issues that may cause a check engine light to turn on and my family's safety is at risk because I do not know if it is only because of a electrical wiring issue. - The problem has been checked by three local auto shops who have all smoked the Evap system but have never found a leak and have each individually told me it is a wiring issue. - It has not been inspected by the manufacturer, police, insurance representatives or others to my knowledge because the car was sold to me by a dealership anything prior to that event I am not aware of. - They first appeared one week and a half from purchase from the dealership. The dealership said it would not fix it because it wasn't in their books. The check engine light turned on when I turned on the car after that time period. I was not driving when it had turned on.

I brought my car in for the 60k service and the check engine light had just turned on. After being told they had to run a diagnostic and keep my car for several days, the dealership came back with "it had a fault for a purge valve. Tested the purge valve with a vacuum tester and found it would not hold a vacuum." I was asked if my emissions was due soon, but I had emissions completed two months ago with no problems. This issue is a big deal and I know VW has had many public issues with their emissions. I barely drive this car and to have such a major issue occur is mind blowing. The dealership quoted me $890. for this repair when I see the average cost of this repair is about $300-400 with parts. I had it completed, but no one wants to talk to me about why I was charged so much when this technically should be a recall.
