Seven problems related to service engine light on have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
2002 chevy Trailblazer service engine soon light will come on along with the reduced engine power light and the vehicle will not go faster than 40 mph. Sometimes it will not go more than 20 and 10 mph. I've taken the vehicle to the dealer and they cleaned the throttle and changed some filters and 2 days later. . . . The same lights come on and the engine power is reduced. The dealer doesn't know what the problem is so the vehicle continues to do this and has been doing this for the past 6 months. There was a recall on the control arms in 2001 that affected the 2002 chevy Trailblazer. I purchased my Trailblazer in 2002 so I didn't receive any recall information. My control arms need to be replaced and I want to know why my vehicle isn't covered under the recall.

The dealer and the manufacturer informed her that a diagnostic would be needed to determine the cause of the failure, which would cost approximately $2,800. The contact stated that she takes her vehicle to the dealer for routine maintenance as specified by the manufacturer. The vehicle has not been repaired. The failure mileage was 72,000 and current mileage was 75,000.
I own a 2002 Trailblazer that stalled for no apparent reason. I did not understand it because one day it will stall at every single red light or stop sign and then the next day it will be fine. When I start to slow down at a stop sign or such the needle in the rpm gauge goes nuts and the vehicle starts to kind of buck a little and then idles really low or it will rev itself up to about 3000 rpm. So when I get to the stop it just shuts off, no lights come on in the instrument panel or nothing. Most times I just put it in park , turn the key to the off position and then start it back up. Runs normal then, well maybe until the next stop. Only one other time did I go to start it back up and it wouldn't start but only for a second and then it did start. Also, it revved while I wa s just driving normally. It has had numerous other problems so when I took it to the Chevrolet dealer I purchased it from for another problem as well as me telling them about this, they had overnight, said they took it for a drive and nothing happened, which I told them that it doesn't happen every time you stop or every day. They also said since no service engine lights or anything came on they couldn't tell what the problem is when they put it on the diagnostic machine. So I have no clue what to do but to keep driving it and maybe someone will rearend me because it stalls in the middle of the highway. I feel half afraid to drive it anymore.
Loud roaring noise - service engine soon light appeared - took it to the dealership - fan clutch needs to be replaced on my 2002 Chevrolet Trailblazer.
Have had many of the problems I read on posted complaints: new engine required within nine months-one year of owning new vehicle, inside driver door panel replaced three times, change oil and service engine lights staying on, hood not closing properly, back glass needing replacement, fabric problems in back seat, etc. , etc. And this morning it is a $200 problem with the headlight switch. Too many things to even remember or name, but chevy has a pretty thick file on me and my vehicle.
I received a notice from Chevrolet stating that some 2002 trail blazers may experience a crackling of an engine cylinder bore liner. This will cause engine noise, poor performance, and or stalls with no engine restart. However, they will only repair after the vehicle is damaged. I have 2 children and do not think it is safe to be driving a vehicle that could stall at any time or provide "poor performance". I have experienced many problems with the 2002 Trailblazer - ranging from the vehicle stopping as I'm going 55 mph, the service engine light staying on, I've received 2 recall notices and then this special policy notice. I think the engine should be replaced for the safety of the driver and other drivers on the road.
Upon starting vehicle consumer noticed the service engine soon light illuminated. Consumer stated took to dealer and dealer replaced the gas tank. Please provide any further information. Ts.
