| On march 31, 1998, the general motors corporation (gm) filed a defect information report to nhtsa for the recall of 55,154 minivans built from august through october 1997 and equipped with traction control because of the potential for brake failure.the brake line to the traction control system modulator valve can contact the wiper arm linkage.the contact wears through the brake line resulting in a leak, loss of brake effectiveness, and extended stopping distances.dealers were to inspect and repair any damaged brake lines, and to install a clip to reposition the brake line away from wiper linkage.the vehicles included in the recall are late production 1997 and early production 1998 model year oldsmobile silhouette, chevrolet venture, and the pontiac trans sport minivans.nhtsa recall 98v-072, gm 98014.the purpose of this investigation is to ascertain whether the scope of recall 98v-072 was correct and whether the 1997-98 models not included in that recall, as well as the 1999 models, should be recalled. | ||||||

| Engine: intake manifold gasket leaking. i followed thru with a complaint to the bbb and to pontiac's 800 number. i was told i needed to have the van diagnosed at a gm dealer before anything could be done by pontiac. my dealer quality pontiac in cocoa, florida looked at the van and agreed the intake manifold gasket was leaking (november 2002). quality informed me it would be about $500 to repair. a phone call to pontiac's 800 # put pressure on the dealer and they performed the work for $100 plus extra for a coolant flush. the total was around $180. supposedly the work came with a 12 month 12000 mile warranty. i think the van had 58000 miles on it when this work was performed. looking back i have a feeling it started leaking earlier. today we have 70500 miles on the van and the check engine light is coming on. the codes indicate that engine cylinder 5 is misfiring. we had new spark plugs put in and will now try new spark plug wires. if that doesn't fix it then we may need to put in new fuel injectors. my complaints to date with this vehicles are: 1. original tires wore out at 24000 miles $500 2. battery died in the first two years. $0 3. drivers side seat belt retractor failed $ 156 - airbag light came on. 4. intake manifold gasket failed $180 5. sliding power door module failed 4 times. $0 6. front brakes drums warped at ~35000 miles $250. front rotors cut and pads replaced. 7. windshield buzzed from the day we bought it (2 years) and took us threatening the lemon law to get it fixed. | |||

| The abs tcds and brake light appears on the dash and stays lit. when it does a fuse has blown and as a result i have no brake light. i do have running lights however. i have been to roper gm 9 times thus far and have been told that it was a loose wire by the brake pedal, a fuse has blown, the wrong size fuse was used (they replaced it), the pig tail that i installed to hook up my golf cart was faulty (i had a new one installed and they said that was all right) then they were going to install a new wiring harness (as yet i do not know if they did because it has only been a week since i picked it up and haven't talked to them yet but will call on monday. they also installed fuses on the brake lines and all that did was not warn me that the brake lights were not working. now that i have it back for the 9th time when i hook the trailering lights up they light up (trailer lights) without the key in the van even turned on. they evidently reinstalled this harness or fooled around with it because it worked perfectly before they got it this last time on turning, braking and running lights with the trailer. when they said they were going to install a wiring harness i took it to mean and know i am right that it was going on the van and not the pig tail. it took them 2 weeks to get the harness and they said 5 to 6 house to install it and when i got there the 8th time they decided not to install it. all in all we have been footballed around 9 times now and it still is not right. have some of the work orders but not others because they told me they couldn't give me a copy as long as the job was open and not dfinished??? *ak | |||

| Anti-lock brake system motor pack failed, causing leak which resulting in total loss of brakes. on 8-23-99, the motor pack was replaced, now the brake pedal stops 1/4 inch from floor. dealer said it was normal. *yc | |||
| 01/01/1999 | |||
| I am not really sure that there is a problem, so this is really more a concern and a request for information. the vehicle appears to have adequate stopping ability, however, i have found that i am able to press down the brake pedal all the way down to the floor. i find this disconcerting because i have not owned any vehicle that displayed this behavior unless it had a problem (i.e. air in the brake lines, leaks, broken master cylinder, etc.). the service manager at the dealership assures me that the vehicle meets all the specifications prescribed in their service manual and as far as they are concerned, there is no problem. i am looking to your organization to find out if you have had similar reports and some sort of reassurance that this indeed is normal. *ak | |||

| I writing to express dissatisfaction 2 major component failures occurred on a vehicle with less than 50,000 miles. the intake leak appears to be a known problem - buyer beware. i can understand disc pad wear, but not major brake system replacement/repair. the mechanic also noted excessive lifter noise; i fear this observation will lead to more major repair work. the dealer has been responsive. my complaint is intended for the manufacturere and other consumers. i will not be a good referral for prospective minivan owners - essentially my entire social base fits the demographic for minivan buyers. *ak | |||

| Did not mark crash, however could not stop in time to prevent hitting curb, my mother had borrowed my car. if a car had been parked there it would have been hit. failure was due to brake line was positioned so that when the wipers were running, the arm that goes back and forth to actuate the drivers side wiper was contacting the line in a sawing motion. the line was covered with a braided shield or tube over the line and it went through both that and the brake line. i did not get a brake warning light until the brake fluid resevoir was down to 1/4 in. the brakes went from being a little mushy to none at all. had i been on a trip on a rainy day, i could have been in a very serious accident. the dealers attitude was very disappointing. there could easily be hundreds of cars out there that are accidents waiting to happen. it took them 7 working days to get a new line in and replace it. they did not even clean off the brake fluid that was sprayed in the engine area from the leak. when i asked about if they reported this problem they said that someone would look into it when they filed the warranty paperwork that no other incidents have been reported. | |||
