Blondefroggie3 Posted September 25, 2018 Report Share Posted September 25, 2018 Hoping for some help. Purchased used in 12/2017. Jan 2018, it starts bucking and kicking back going up hill and when getting to 55mph. Get to dealership, said spark plugs and coil 3 were bad. All replaced, good to roll. Fast forward July 2018, start getting the kicking again when driving uphill. Took 3 visits and into August (and a lot of complaining that something really was wrong...) for them finally to say the coil burnt again. Replaced and good to roll... September morning go to start the car and I get black smoke out of the vents and a burning smell. Get to the shop, pop the hood and you can see the engine bucking and jumping all around.... and they then tell me coil 1-3 are burnt up and spark plugs bad. Go to get it changed after parts arrive, and they get in and said only coil 3 is bad.... so replaced last Wednesday. Over the weekend took a small out of town get away, suddenly getting the slight shake back. Got back and was at 500ish miles since I left the shop This morning on the way, it’s back to the way it was, bucking up hill, feel it jumping when idling and everything.... so I’m 99% it burnt again already!!!!! Has as anyone else had this issue???? V4 motor.. Quote Link to comment Share on other sites More sharing options...
OhareFred Posted September 25, 2018 Report Share Posted September 25, 2018 Plugs the the 4cylinder are good for 30k (if I recall correctly) and need to be copper (I think anyway). I have a V6 that’s why I’m not positive. Putting “upgraded” plugs in does not work well with these engines. much discussion on the forum. Search spark plug for 4cylinder or perhaps someone else will chime in..... Quote Link to comment Share on other sites More sharing options...
jkeaton Posted September 25, 2018 Report Share Posted September 25, 2018 You should have warranty left. Force their hand or find another dealer. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
2late4u Posted September 25, 2018 Report Share Posted September 25, 2018 my daughter had a problem couple yrs ago with the coil going bad on her caravan sounds like what you are having problems with, they ( regular garage not the dealership) kept replacing her coil said it was bad, lucky thing was the coil was guaranteed for 1 yr and it kept going bad about every 3 months ( this was her postal van) so it started bucking and messing up so she took it in and it ran good for him but he said leave it and let me try it for a couple of days he ended up finding out the wires in the connector were shorting out and thus making the coil go bad he replaced the connector from the wire loom and no more problems for her. have them check for shorted or bare wires. good luck OhareFred and jkeaton 1 1 Quote Link to comment Share on other sites More sharing options...
