The air bag light illuminated on the car spontaneously and stays lit at all times indicating a fault in the system. From all reports on various porsche discussion forums (thousands of incidents that have been reported and discussed), this is a common problem in the first generation porsche boxsters. It is a defect in the seat belt buckle and seat belt ground caused by corrosion of the contact points for the seat belt that triggers the light. The purpose of an air bag light is to inform you of a defect in this safety system and to notify you that the system will not operate as it should. While there is apparently a tsb that was issued by porsche, once your vehicle is out of warranty they will not repair it under the tsb for free. This is a widespread and common safety defect that doesn't appear until after the car is out of warranty. The cost to repair this problem is approximately $1500.00 through porsche. Considering most porsche boxsters from 1997-1999 suffer from this problem, it should be a safety recall and repaired by porsche at their expense.

Recalls 1
Power train: automatic transmission
- What is wrong
- Certain 2-door convertible passenger vehicles equipped with the tiptronic (automatic) transmission may have been produced with an incorrectly adjusted key-lock-cable down to the shift selector. If the key-lock-cable is not adjusted correctly, it is possible that the ignition key will snag upon being removed fro the ignition lock or the slector lever can be shifted from position "p" with the ignition key removed and the locking button operated.
- Risk
- If the selector lever is then shifted from position "p" to position "r, n or d" with the vehicle parked, and if the parking brake is not on, the vheicle will not be secured from inadvertenly rolling away, increasing the risk of a crash.
- Remedy
- Dealers will inspect the cable adjustment and, regardless of the results of this inspection, the key-lock-cable must also be adjusted. Owner notification began july 15, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact porsche at 1‑800‑545‑8039.

What 1998 Porsche Boxster owners say
Most recent owner complaints, unedited.
1998 porsche boxster. Consumer writes in regards to vehicle engine problems. *smd the consumer stated between 1997 and 1998 porsche produced an engine with two known flaws. The first, was the engine block, that was too porous. It caused the cylinder walls to crack, causing loss of all compression in the cylinder, and therefore rendering the engine useless. Secondly, they designed a faulty intermediate bearing shaft, that had a high rate of failure, and destroying the engine. Also, the computer module was located in a position that exposed it to increased probability to short circuit.
My vehicle had only approximately 65,000 miles when the horn started to malfunction. The horn started to routinely deploy on its own. In the short term I had to have it disconnected by my regular mechanic so I could continue to operate the car. I called barrier porsche in bellevue washington where they seemed to be already aware of this issue. I learned the parts (clock spring and something else) cost close to $600 and I assume at least a couple of hours of shop time. With sales tax I'm sure it would cost $1,000 to repair this important safety equipment that should never fail .please help! This should clearly be a recall item.
We bought a 1998 porsche boxster in aug 2009. Serviced as required. On 9/7/10 out driving, stopped at a stop sign as we proceeded through the stop sign the engine died, white smoke came pouring out the back. Had it towed to mechanic and was informed that then motor had seized due to the ims (intermediate shaft). Car had approx 34k for mileage. Contacted porsche america and was basically told there was nothing they could do. After researching on the web, this appears to be a pretty common problem with the 97-99 boxsters. The cost to replace the motor with a used motor was approx 9k and they would be using the same type of motor with the same design flaw. The car has been taken to the salvage yard and we are out quite a bit of money.
1998 porsche boxster airbag light, related to seat belt buckle, known issue with a fix that has a part number, but porsche never had a recall so the only way they will replace it for free is if the light came on within the warranty time. Cost out of warranty $500 to $1500. This should not be a warranty issue but a safety issue, if they knew that the part was faulty they should have recalled the part and fixed every model that came out with the old design. There are many reviews all over the internet by 97' to 99' boxster owners. 99' is this year they came out with the fix, but if you kept your porsche clean and garage kept it would be well past the warranty before the wires faulted and the light come on. Although they say it is not a safety issue and that the airbag will still deploy, by having this fault active, you will not be able to tell if a true airbag fault that will affect the airbag operation really went off.
I have a 1998 posche boxster. The car has a problem in that the airbag light will come on and the owner will not know if the airbags are working properly or not. Porsche has had over 7 fixes on this issue and none have worked to date. They have not replaced mine under warranty. I have been informed by my local porsche dealer this is an on going problem. Porsche north america refused to fix this problem because the car is out of warranty.
I recently purchased the 1998 porsche boxster, automatic transmission, and have discovered a latent defect which pcna designates a305, and ntsb has additional recalls relating to the same defective part on the same model and year involving the ignition switch and attached ignition assembly. The latent hazard is in the ignition switch which is damaged within the ignition assembly resulting in electrical failures and resultant fires. I have determined through pcna and porsche that the electrical assembly was redesigned due to inherent (design) defect to correct the failure of the ignition switch but the newly designed replacement part (redesigned electrical assembly was not replaced in my car or other numerous cars. Several boxster owners have paid for the new part and labor totaling in excess of $400.00 but pcna (porsche) has done nothing to fix the existing defective switch's and assembly. This is a part that repeatedly fails and remains a serious latent defect undressed by porsche. On my car the only thing corrected was under campaign no a305; that was done in 2003 according to pcna. The repair they did does not address the defective ignition switch and switch assembly. A 305 involves the same assembly but involved tightening a cable so the car does not run while in park and the ignition switch fails to interface with the immobilizer system. Please indicate if additional information is needed regarding my car and the problem I have experienced.
Dt*: the contact stated while attempting to turn the key, the ignition switch would not turn or would turn too far causing the instrument panel to be inoperable. There was a the federal safety agency recall, # 98v113000, regarding the ignition switch. The vehicle was not included in the recall due to the VIN. Updated 12/01/06
1998 porsche boxster air bag warning light illuminated over a year ago. *ts the consumer contacted the dealer and was told that there was a know corrosion problem with the contacts in the air bag electrical system. The dealer told the consumer that the front seats had to be removed to correct the problem and that the wiring harness had to be replaced. The consumer believes the manufacturer should be responsible for the cost of the repairs but was told that since the vehicle was out of warranty the he would be responsible for the repairs. The emission warning light illuminated. It was determined that the gas cap was defective.
Interior door handle cable failure. Both interior door handle cables have failed. This has made the vehicle impossible to exit in the event of an electrical problem. I have contacted both the local porsche dealer and porsche north america and have been informed that they will not fix this safety problem at their expense because the car is no longer under warranty. Porsche is aware of this pervasive problem but will not do anything about it unless a the federal safety agency recall is issued. A search on the internet show this to be a common problem to '98 and later boxters. See: http://www.986faq.com/10-0/problems. Asp#001 please issue a recall to fix this safety flaw. Thank you.
