I had a 1997 pontiac bonneville. while i was driving down a highway in michigan, the engine compartment suddenly caught on fire. i was not speeding, and my car was perfectly serviced and maintained. by the time the fire service got there, the whole car burnt down. it took less than 20 minutes for the whole car to get burnt beyond recognition. *tr | |||

Car completely shuts down while decelerating at anywhere from 30-55 mph. sometimes can restart, sometimes not for a half hour or so. the car's engine coolant has leaked out onto engine. car shut down, no power, no steering, no brakes, then the coolant spilled out everywhere, engine started smoking and now the engine has stopped working even after replacing head gasket. car had been into dealers numerous times to no avail. no one could identify the problem. now have a car that had to be towed and is no longer functioning. numerous fuel injectors were replaced in hopes of stopping the stalling out and shutdowns, but nothing has worked. waiting for a couple of quotes on what it will take to try and fix the engine or most likely need replaced. this has been happening since the car was fairly new. | |||

I paid the stated amount to replace a component referred to me as a "plennum". the symptom my car was having was, it was overheating. it is made of plastic and is mounted on the top of the 3800 engine. little did i know, that the damage had already been done. the failed part had leaked coolant into the engine. a week and a half after having the plennum replaced, my car broke down. i have been advised that the leaking coolant into the engine from the plennum had caused premature failure of a "rod bearing" in the engine. the coolant i'm told ate away the bearing lubricant. i am told my only option at this point is an engine replacement. i am not a car mechanic by any means and suspected nothing, and was told nothing. i understand and accept the fact that man made products wear out and need replacing. this to me seems to be a poor engineering flaw that costs a lot of money to fix. i did not include the $2000.00 engine replacement in my total repair cost above. the plastic plennum part, by the way, was replaced with another plastic part. i told the driver that was returning me home while the plennum was being replaced, that i was intending to trade my bonneville in on a montana minivan this summer. his reply to me was that they are experiencing the same problem with the montana, as well as other vehicles with the 3800 engine. it sems clear to me that there is obviously a problem here that needs to be recalled. | |||

The intake manifold gasket on my 1997 pontiac bonneville 3800 series engine failed causing coolant to gain access to internal engine parts. this caused the engine to seize and become totally inoperable requiring the engine to be replaced at a cost of $2200.00. this failure also happend in a pontiac grand prix, that i also owned, with the same series of engine. the cost of the repair to the grand prix was approx. $650.00. the engine in the grand prix did not have to be replaced. looking at and reading the various gm message boards on the internet, this problem seems to be fairly prevalent with the 3800 series of engine. gm continues to ignore this with no regard to the consumer. | |||

While driving a 100 miles from home the car overheated & had to be towed. we found that the problem was due to a hole in the air plenum in the upper intake manifold. we have found that there are over 20 such cases in our small community alone. all on 3800 motors in pontiac's. this is a four hundred dollar repair bill that occurred only because pontiac decided to use plastic in their part which in turn melted & caused our motor to overheat. i hope that pontiac will recall these plenums & reimburse us for the cost of repairing & towing our car. if pontiac would call their dealers they would find out just how many of these parts have malfunctioned. *jb | |||

My car wouldn't start and there were no electrical components functioning. i called the car dealership where i purchased the warranty and was told to make sure i didn't have a dead battery because that was not covered under the warranty. i called the towing company and they attempted to charge the battery. battery would not charge; the car went puff and caught on fire. when the wrecker driver attempte to start the car, he heard a loud pop and smoke was rolling out from under the hood. he opened the hood, battery was intact, however the engine was on fire. after fire was extinquished, he found the plenum(?sp) blown off the top f the engine and the oil filtler tube was blown out of he top of te manifold. warranty company would not cover due to the fact the car caught on fire. they said my car ins should cover it. however, i believe the fire was the result of a previously existing defect. i was told the foam used to extinguish the fire could possibly have caused more problems in the engine. was i supposed to let the car completey burn up? i don't think so!*ak | |||

Twice while driving at approximately 50mph car lost all power for a second or so and then came right back on. during this second or so, i have no power brakes, steering, nothing. this is definitely a safety hazard, if it happens at the wrong time, it could cause a serious accident. one time before i remember at least a month ago, the radio just cut out for a couple of seconds for no reason, and the day after the first time my car lost power, the abs light came on for a couple of seconds and then went out. i don't know if these are related, but something is wrong, i don't know if it's the engine, electrical or computer. *ak | |||

The plastic intake manifold on my 1997 bonneville warped causing coolant to leak into the engine which then seized the engine. replaced intake manifold and rebuilt both engine heads. total cost was $1,525. my mechanic told me this is a common problem on the gm 3800 series engines because the upper intake manifold is plastic. about 2 weeks later, a rod bearing failed. i was told it failed prematurely because coolant had entered the engine. i do not have a repair estimate yet. i believe all of these problems are related to the defective upper intake manifold. *ak | |||

The intake manifold or the plemium whatever you want to call the thing wore out and all of my engine coolant went into the fuel cylinders and locked my motor down i was headed to macon ga from douglas,ga going to the hospital were they had transfered my brother and here i am in perry,ga broke down because pontiac puts a plastic intake manifold on a motor i feel like pontiac should have to pay for this part being replaced. i also have trouble with my car surging between 35 and 55 miles per hour this is the sorriest car i have ever owed and i have owned 2 grand prixs before this car but liked the body style of the bonneville and i rhought that it would be a good car but boy was i wrong i bought the car in august,2002 and have spent enough money on repairs on it that i could probably done paid for another grand prix.after reading all the complaints on this sight i feel they should have a recall on them for the transmissions and the intake manifolds because they all seem to be related to me .people pay a lot of money for there cars and still have to put money in repairs its just not fair .*ak | |||
