Filed Mar 4, 2021 · Electrical, Engine · 100,000 miles · MI

Car continuously gets a reduced power message and goes down to 25 MPH. In mid january did the same thing, but stalled on i90 ohio turnpike. Almost hit by a semi truck. Have had the car in the shop no less than 5 times for the same problem. At gm and non gm repair shops. We have had this same reduced power on city roads, and the highway, it seems always when it is wet, rainy or slushy. It really appears to be a water causes the problem. We have paid for two sets of throttle body, speed control sensor and harnesses. The problem continues to persist and appears to be dangerous.

This has been happening for several years, and happened again yesterday..... Pulled out onto 4 lane divided highway and traction control light came on, dash said "engine power reduced", but did not seem to be significantly low on power. Drove about 5 miles down the road, then car suddenly died. Was able to pull over to side of the road (with three small children in the vehicle), tried to restart the car but display said "starting disabled, service throttle". Waited about 5 minutes and car restarted. Was able to drive home, no reduced power but check engine light remained on. I have seen many comments online from others who own similar gm vehicles that have had similar issues. We have also had similar issues with our 2011 suburban, although no stalling. There should be an immediate recall for all 2008 - 2011 gm vehicles to repair this issue, most likely accelerator pedal position sensor.

While the vehicle was in motion on dry pavement, the traction control light came on, followed by the check engine light then the car stalled and had to be be eased off the highway. Tried to restart the vehicle several times. After it sat for a couple of minutes tried one more time and the car restarted and drove home perfectly. Researched the issue online, and there are entire forums in edmunds dedicated to this very problem. Definitely a safety issue with this vehicle.
