Car Stall problems of the 2008 SAAB 9-3

My car wouldn't start so I replaced the battery and the crankshaft sensor. It drove fine and then I parked it and went out a little later and it would jerk and try to stall while I was driving, sputtering like I was running out of gas. If I pressed the accelerator, it wouldn't accelerate and then it would surge forward. I ran some errands and it drove fine. After my final errand, the car struggled to start but did and idled really roughly. I put it into gear and it died. I couldn't get it started again. After reading other posts, this seems like an issue with these years and veey dangerous.

I brought my 08 SAAB 9-3 to a shop for a compression test cause it kept stalling when I would go to start it, it's an automatic. I was told my intake valves were wearing down and it's due to gms faulty valves. Yesterday my car started ticking while I was driving and I lost almost all my power, come to find out my valves were about to snap. Now I'm making payments on a car I can't drive and gm refuses to fix this issue and there are multiple cases of this happening to 08-10 SAAB 9-3 with the gm factory valves.

Rough idle and start on cold starts. This issue is well known in the SAAB community due to gm putting weak material in factory fuel injector valves. Engine loses compression until car is warm, but may result in stalls or limp mode.

Reached 100k miles, and car began running very rough. Engine light came on and diagnosed as bad ignition coil. Paid for tune-up, ignition coil, and and fuel service. Less than a month later, same issue. Car running fine, then suddenly almost stalls and engine light blinks then stays on - car runs very rough at idle and acceleration. Replaced 2 more coils. Less than one month issue, same issue - car running ok, then just almost stalls and runs rough - engine light blinks then stays on - relaced #5 coil. When diagnosing, service tech advised that issue was likely worse, not maintaining compression - likely required valve job. Have already paid several thousands of dollars on ignition coils and other service to dealership for this issue, now facing large bill for valve job.

I have been having this problem with my car for a while now and couldn't figureout what the problem was. When started from a cold start would take 2 or 3 times to get the car running it would stall out and run really rough. After a number of trips to the shop that maintains my car they researched online that this was a common problem for Saabs with this engine and gm isn't willing to do anything about it. I had to spend just under 2000. 00 to get this issue fixed. I see there are a bunch of people posting about this same problem the intake valve issue is a known issue with gm supplied intave valves on 2007-20011 Saabs with the b207 motor.

Intake valve issue - car will not start on a cold day and, sometimes at a stop sign /light, will stall - had to two mechanics depict the issue and it is the intake valve issue - many SAAB's have reported this issue and nothing was done by gm - I called gm and they said that they are not responsible - this issue has been reported several times and there are several threads as well.

79,000 miles began with sluggish cold starts until warmed than began to run o. K until stopped turning over. Another owner of gm screwing the public with crappy valves installed in these engines. When will there be enough complaints to create a recall. Ordering parts from east coast SAAB parts store and looking for reasonable and knowledgeable California based mechanic. Expecting to pay approximately $2k. Will update this complaint when job complete. Another gm disappointment in car ownership!.

I first noticed a difference in how my car worked about a year and a half ago. I purchased it certified pre-owed from a certified SAAB dealer at the time. When I first noticed the "cold-starts" I thought it was just normal wear and tear and maybe needed an oil change. I always use premium gasoline and get the vehicle serviced regularly by the dealer. When I took it to the dealer in the beginning of 2014, the technician said he's familiar with the problem that I was having. He says the issue is with the compression valve. He told me that I was "unlucky" that I purchased this car because SAAB manufactured 2007-2009 9-3 model engines where the valves were made of weaker metals that when surrounding metals. As the edges of the valves impact the engine walls, their original convex designed became concave, thus causing a loss in pressure and combustion. (I'm not an engine savvy guy, so please excuse my lact of terminology). So, he quoted me about $3,000 for a valve replacement. That's rediculousness! how can gm produce a vehicle whose valves will deteriorate after normal wear and tear? this has led to not only cold starts but also decreased responsiveness on the highway. Sometimes when driving, I would apply the accelerator and my car shakes for a few seconds. When giving a ride to others they look at me like, "that's not supposed to happen. " my car hasn't stalled or shut off while driving, but I'm guessing if I don't get this fixed soon it may happen. There is a safety issue that I'm sure gm is aware of; accordingly, there needs to be a recall to get this issue resolved.
