Traveling on hwy 35 in dallas texas and message appeared on instrument cluster "reduced power mode". Vehicle speed dropped to 20 MPH (posted speed was 70 MPH). Had to have vehicle towed to dealership and a fix has not been determined. The dealer so far has charged me $900 and it did not fix it.this same problems been posted on gm forums, gm truck forums with these same results. There are hundreds or maybe thousands of complaints for this issue. It is very unsafe.

Driving on residential road and vehicle suddenly reduced speed to 10 MPH. Message displayed "reduced power mode". No one knows how to diagnose. All repairs I have read on the internet forums are expensive and the problem eventually returns. This problem is intermittent and can occur at any time. The most concern is on the freeway where your vehicle is reduced to 10-20 MPH and the speed limit is 70 MPH.

While driving on the freeway my 2002 suburban with a 5.3l flex fuel equipped vehicle just would stall with out warning and cause me to lose all power steering and other item related to the engine running. I have to wait for the vehicle to cool down before being able to restart it. No code would show on the on board computer and after looking at other recalls it pointed to the crankshaft position sensor going bad. I am going to change it out in the morning. I have read others having this same issue in this year model and think chevy should do something about it.

While driving suburban on a long trip over 2 hot days, engine quit without warning once each day after many hours of driving (5 people with luggage, no trailer). First day occurrence was after driving in city traffic with many stoplights but speed was about 60 MPH at the time and quickly lost power and died. Second day was at sustained 70+MPH and quit suddenly. Both times needed to pull over and turned off for a minute after failures and restarted on 2nd try and continued on for another 20+ miles before stopping for the day (first day) and stopping for dinner (2nd day). Fuel in gas tank was half full on first day and 3/4 on second day. This vehicle exhibited same failure numerous times 2 years previously on hot day pulling trailer.

Sudden loss of power steering and very heaving steering requiring great effort. I made a hard u-turn and then found the steering was extremely heavy. It took both hands and a lot of force to steer the car. I pulled over, popped hood, and saw nothing wrong. No dash malfunction lights were on. At repair, the steering pump shaft had sheared where it necks down from about 3/4" to 3/8" diameter. An internet search provides many instances of the same failure. The dealer replaced the pump with a different part number which does not have the variable effort steering feature. I very much don't like the resulting lack of road feel and am pursuing that problem with the dealer. This sudden steering pump failure is a definite safety related issue.

While driving on the houston tollway at 65 MPH, my 2002 suburban suddenly and without warning lost power and the engine shutdown. I managed to get the vehicle onto the shoulder without incident after attempting to restart the engine while trying to steer clear of traffic. The vehicle would not start and was towed to lone star chevrolet in houston, texas. The bill was 1045.10. They replaced the fuel module and the fuel filter and told me that there had been some problems with gm vehicles dating back to 1999 models on the same problem. Mine had only 70158 mi. I think gm should reimburse me for the cost of repair. I talked to a customer who had a similar problem on his 1999 gmc suburban and they filed a complaint with gm and was reimbursed for the repair. Fair is fair and I expect nothing less from them.
