2011 Volkswagen Jetta: misfire or rough idle

Filed Sep 28, 2020 · Electrical · 22,000 miles · FL

While driving on a city street my check engine light came on and started blinking then stopped blinking and is now on along with the epc code. This is the 3rd time in 2 years my vehicle has done this so I know its the ignition coils causing a misfire. My vehicle now shakes when im stopped and has a ticking sound at red lights, this is very unsafe and needs to be corrected 3 times in 2 years is way to many times for my ignition coils to be replaced.

My volkswagen jetta 2011 seems to have misfire. It has a check engine light on. The car shakes when slow down and/or at stops. Vw certified mechanic tried changing the plugs, and cleaning the valves but nothing helped. He also tied shaft crank sensor that did not help either. Finally the diagnosis report indicated that it's timing chain issue that need to be replaced.

Crank case is not on recall so it's not covered under warranty. The cost is 4200.00. At what point will it go on recall. Without the repair the car is dead in the water. Warranty company will not pay for anything that's on a technical service bulletin. Also called vw verified is on the technical service bulletin. It's very dangerous as the car oil light comes on and runs rough and just stops. July 7 2017 bulletin 15-16-02 (v151602)

Vehicle stalls intermittently since purchase, commonly when exiting a freeway to a stop or during rush hour(stop/go)traffic. Before stalling, vehicle will jerk, rough idle, and delay acceleration. Stalling may occur at a stop after high speed, however stalling has also occurred during driving after a high speed to low speed departure. When vehicle stalls during driving, both the wheel and brakes lock up commonly. It takes putting it in neutral while rolling and attempting to start several times before ignition kicks in. This has been dangerous as the only braking would be a gradual emergency brake pull and there is no additional steering, thankfully I have had straightaways the times it has happened, however I have been forced to go through red lights with my hazards on, laying on the horn. Vw has attempted repair 5 times for same issue with no resolve. Lights and codes come and go intermittently after stalling. One or both of the previous issues mentioned occurs on a daily basis as of the moment. The ftc, bbb, and attorney general for the state of michigan have all been made aware of the situation and the attorney general's office recommended I report it to you.

Driving down the highway at about 55mph, started switching lanes and stepped on the gas to accelerate. The car sputtered and the engine vibrated. The car felt like I was going to stall driving in the high-speed lane. The yellow check engine light came on and epc light started flashing. Swerving back into the lower speed lane I couldn't even keep the car at 55mph. I had to pull over on the highway to see if I could make sense of it. After turning off the car and then back on, the lights went off and the car was fine. I took it too the mechanic and they said they couldn't find anything wrong after $85.00 diagnostic. The car ran fine for 2 days until the same exact thing happened while driving on the highway again. This occurred on and off intermittently about every 1-2 days for about 2 weeks. Three trips to the mechanic within those 2 weeks and with each visit there was a computer connected to the car and a full systems diagnostic reported that there was nothing wrong with the car. It became dangerous for me to drive the car and even more so to drive it on the highway. After the second week the lights finally came on and stayed on and the problem was diagnosed as the engine misfiring in 2 of the cylinders. The mechanic changed with the ignition coil on 12/15.2014. The engine ran completely fine without any issues until last week, 3/19/2015. At 3 months and only 28,000 miles on the car the same problem started to reoccur while getting onto the highway and attempting to accelerate from 40-45mph. It started just as it did before intermittently and about 2 weeks later the engine and epc lights were on permanently again. After the mechanic confirmed that it was the same issue with the same component we changed the same part again. I am expecting to be changing it again in 3 more months, if I still have the car.

This car has had multiple ignition coil problems causing a misfire and a rough rumbling engine. The ability to accelerate is greatly reduce leaving you vulnerable to car accidents in certain situations like pulling out at an intersection. This is the second incident within a year of ignition coils failing. Now at 42,000 miles it is not covered under warranty. The first incident was extremely troubling not being able to maintain a constant speed with a line of traffic behind me and no where to pull over. This is a severe safety issue and should be addressed by vw.
