Vehicle goes into reduced power modes at any highway speeds. The codes involve a throttle body, crankshaft sensor and pedal. This is extremely damgerous at highway speeds since vehicle is immobile.

Needed recall for hummer h3. "reduced power/service stab system/traction" notification that appears without warning, and immediately drops the engine to almost no ability to accelerate. This began happening in local traffic, then on the interstate at high rates of speed. Gm has been notified of this issue, even after numerous attempts to repair this very dangerous malfunction without success, they are unwilling to address it with a recall. The most dangerous of the numerous times this happened was on 4/27/17. I had just left moses gm of charleston, wv after they had repaired the vehicle for this issue. I drove approximately 5 miles on interstate 64 before losing power, and almost being struck by a vehicle on the south charleston bridge. The dealership towed me back to the service center where the vehicle was once again unsuccessfully repaired. It seems that this is an issue with gm vehicles around the same time period, and not just the hummer line. Any help would be greatly appreciated.

P2135 throttle/pedal position sensor/switch a/b voltage correlation that puts the vehicle into ?stabilitrak disabled", "traction control disabled", and "reduced engine power". While there is a tsb#11-06-04-007b regarding this issue and warranty coverage; unfortunately it does not apply to my engine. However, since this is a widely know issue, and this vehicle is experiencing the same conditions, one would think that my vehicle would be serviced under this tsb extended warranty coverage. 12/04/2014: first service attempt: clear code everything tests fine, let?s see if it happens again. 12/10/2014: second service attempt: both throttle body and acc pedal position sensor tested "good". Weak battery - replace battery. 12/22/2014: third service attempt: tech replaced accelerator pedal. Relearned throttle/idle. 12/26/2014: forth service attempt: relearned throttle/idle procedure. 01/13/2015: fifth service attempt: reprogram and apply 6 updates to ECM. 01/14/2015: code thrown again: dealership advising to replace throttle body (but uncertain that this will fix the problem)?
