What owners say
Oil leaking ,traction control keeps shutting on and off,evac leak,in motion,smoke and oil stains coming from car. Scanner reads misfire needs plugs and wires but just got plugs and wires.
When I start my car, it will stall out, not turn over or it will idle for a few seconds, then immediately shut off. I mean shut the whole car down so nothing electrical can work at which point my key will be stuck in the ignition and I cannot get it out. I am able to restart the car normally, however the steering wheel vibrates along with the body of my car while in motion and while parked. While making a left turn through a four way intersection, I lost control of my power steering and the wheel was stuck at first and then swung all the way back which spun my car around. This car has had 1 owner before me and I have kept up with all of my oil changes and tune ups. In september of 2018, I had a similar issue with the vibrating and was told that a cylinder was misfiring and that I needed a tune up. I spent $587 on these repairs. My vehicle was at 98,890 miles. It is may 2019 about 9 months later my vehicle is at 108,630 miles and I am having the same and additional issues not even 10,000 miles more. I have documentation from the mechanic from my cylinder repairs that I have requested to be faxed over to me.
Random misfire code won't go away since weeks after purchasing my vehicle which was then under warranty. The dealership replaced the car computer & ignition coil module, spark plugs and the code temporarily went away good enough to pass emissions. They also performed the key recall the code keeps coming & no mechanic or dealership can tell me why but they keep taking my money for a temporary fix.the dealership said I needed a new catalytic converter. I have replaced 5 sensors, the ignition coil module twice, the catalytic converter, all six fuel injectors, the fuel pump and had 3 major tune ups. To date the engine light shuts off temporarily and always returns with the same two codes p0300 & p0420. It flashes occasionally but stays steady most days.no work done is turning the engine light off for good.
The car has just died while driving, had towed to 1 garage (july 2014) and the coils and ignition module were fried and needing replaced. Had that done then 6 months later (dec 2014) same issue. Now 1 year later again coils misfiring and igniton module needs to be replaced. Luckily was able to move off to side of road and not cause an accident.
Takata recall / my car had a gm recall 15757. It involved the replacement of my engine front valve cover and front valve cover gasket. I took it to the gateway buick gmc on 3/5/2016. After the job was finished I found out my engine plastic beauty cover was missing. I was told it didnt fit because of the new parts. It is unexceptable that my engine is left exposed and there wasnt a newly designed plastic beauty cover. I am not happy with the result. Plus, my car is now misfiring and before I took it in for service the car was running fine and not misfiring. My spark plug wires were loose and easily detached from the connection where the spark plug connects as if it was pulled carelessly. I regret taking my car in for the recall. My car should have no problems period after service.
R reading some of the complaints that have been submitted, I don't know where to begin or if I have enough characters to express my frustration with my 2006 pontiac grand prix gt supercharged. My recent issue is that the car keeps cutting out and stalling.I took the car to the dealer and spent $110 on a diagnostic after 4 other local mechanics could not duplicate the issue or pinpoint the problem. The result from the dealer's diagnostic was: p0300 multiple misfires; needs 3 coils and ignition module replaced $1090 installed; also has a bearing going out in the super charger and there is a harsh 1-2 shift. I just spent about $1000 getting fuel pump, back wheel bearings, right brake hose, and valve cover gaskets replaced. Rack and pinion had to be tightened although it was replaced twice last year (bad part the first time). I have had power steering pump replaced, water pump replaced, air intake tube/valve replaced. Paid dealer for diagnostic because no codes or indicator lights were on and 4 different mechanics couldn't pinpoint issue. Dealer stated they have up-to-date equipment and code p0300 came up. Car intermittently hesitates to start. Car acts hesitant after car starts after hesitating to start. Interior seats and dashboard has cracked. Abs/traction seems to be failing, car still moves after applying foot on break...slides a little, no immediate stop, even after I have had complete brake work performed (wheel bearings, pads, rotors, hubs, etc.). Supercharge switch has been replaced and elbow tube off the motor block (think that is correct, it's an l-shaped small tube). A lot of repairs have been made. The car runs smoothly when necessary repairs are made. Hate to get rid of the car with all the money and care that has been placed into the car. I am not in a postion to purchase a new vehicle but with the miles I don't want to put extensive $. Gm won't assist.
Car just dies while driving replaced maf sensor map sensor was replaced previous. Took car of problem. 2 month later sputtering code came back catalytic converter. Had that cut off. 2 weeks later car won't start changed crankshaft sensor started but misfire coil packs changed and ignition control module. New spark plugs and wire. Car started ran perfect. Next day car wouldn't start. Went back to shop mechanic started looking at some wires car wouldn't still start. Next day car starts up just fine n running perfectly. When its not starting it will crank just not fire. Haven't checked to see if it will run yet today though. Brought it home yesterday. Could a key cause it to crank and not fire.
Vehicle began to run rough. Then immediately lost power steering and stalled. The engine died followed by flames from under both sides of the hood. No smoke was seen before the fire began. No lights came on to indicate a problem. In no time, the entire vehicle was engulfed in flames. The car was a total loss.
Driving to work as normal and took off from a full stop when all of a sudden the car was going nuts trying to catch a gear. Service engine light blinked than stayed on and now when driving between 1st and 3rd gear car sputters, shakes, slams into gear hard and I need to keep giving it gas to get it to catch so I move and don't get stuck in the middle of making a turn. It is a 99 grand prix se 3800 engine sedan and I brought it to my good friend who owns a shop and the computer said it was a c1 misfire solenoid or something like that. On my engine, the left side has 3 things that 2 spark plug wires goes into each and are labeled 1/3, 2/5 and 4/6 (might be wrong on numbers). The code was saying the first one that says 1/3 was bad causing the misfire. We changed the part and the service engine line went off and car drove fine. The next morning I went to go work and at the first light, I go to take off and it starts shaking and sputters and becomes almost impossible to drive. During this the service engine line blinked than stayed on steady. Now the car has trouble catching a gear from 1st to 3rd and it feels like a roller coaster just trying to take off from a stop or during heavy traffic. I replaced everything else on the car and give up with problems. There has to be a defect that pontiac won't admit.
