general 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.

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.

At 65 mph, the gear shift knob, shift cover and assembly separated from the car - the base-metal stick shift was all that remained, and thus the safety latch that prevents car from being shifted into reverse, instead of a forward moving gear, normally attached to the exterior, was now missing. Alas, safely shifting into any of its 6 gears, was not an option . . . It's odd, but per its original manufacturing specs, the entire transmission system in the 9-3, has zero locking mechanism to keep the knob and cosmetic housing from separating. Numerous other reports have been reported to dealerships and across the internet. Gm still covers 9-3, 2008, under its warranty policies.
