Gas pedal constantly sticks when trying to accelerate which causes the vehicle to lunge dangerously and unexpectedly (I.e. From dead stop or while already in motion if you remove foot from accelerator pedal and then try to accelerate again). This is an extremely hazardous situation, especially when trying to start out from a dead stop and you have to increase foot pressure on the accelerator to unstick it causing the vehicle to lunge. The federal safety agency consumer complaint pages are full of this exact same scenario, involving this vehicle and this problem, and the manufacturer has not accepted ownership of this obvious malfunction and obvious major safety concern. This should be handled by the manufacturer via a saftey recall issue.
1999 Chevrolet Silverado acceleration complaints
Page 4 of 4: complaints 71 to 95 of 95, newest first, as owners wrote them.
Increased accelerator pedal effort caused by sticking parts in throttle body. Chevrolet tbsooo6o4 confirms the problem but does not offer help to owner.
In order to get vehicle to move driver has to press really hard on gas pedal, then car will take off. Dealer said it was caused by carbon build up in throttle body.
After pickup has been driven for a few minutes, like to a shopping center, and the engine is stopped. Upon restarting engine the throttle will stick, requiring an estamated 30 to 80 pounds pressure to activate. Then, it will suddenly depress causing the pickup to "jump." this is dangerous, particularly backing out into traffic or trying to back to hitch a trailer.
When consumer applies gas pedal it sticks, he has to press very hard to get vehicle to accelerate, when vehicle accelerates it jumps and could cause an accident. *ak
Gas pedal sticks. Makes truck jerk quickly forward in drive gear, or jerk quickly backward when in reverse. The part was replaced at about 34000 miles, however the same problem happened again at 67000 miles. Less than 34000 miles again. This is a severe problem with the gas pedal sticking. It is hard to park the truck, back the truck up, or start movement of the truck in tight places. The truck could lurch out of control and hit another car in front or rear. The gas pedal has to be stomped to get it unstuck. This could lead to an uncontrolled acceleration.
Gas pedal sticks if foot is removed for any reason, be it coasting into a turn, starting out from a stop. Speed of vehicle does not matter. When the foot pedal engages there is sudden excelleration, cause passengers head to wipe forward. On icy conditions this has become a danger in itself. At the gas station inching up to pump it has locked up and lunged forward almosting hitting a vehicle in front. I have notifed the dealership. I have also spoke to three other people who have this same, year, make and model and all say they have the same problem. Two of them have had repairs done on the gas pedal. Window on driver side (electric) was being rolled up half way up window cable broke and window slammed down inside door. Both passenger and drivers doors seem loose when rolled down as you can hear them rattleing inside. Controls are intermittent and when temperature drops below 30 degrees don't work. Passengers window 11/17/2000 wont not go up or down during temperature below 30. Vehicle was not subhect to elemints as it was inside for repair to driver window. New motor and regulator need after 1 1/2 years. Dealer informed no information.
The throttle sticks (hangs up) from the idle position causing dangerous jack rabbit lunges from zero speed. Throttle cable retaining ring sticks in guide sleeve.
When we first noticed the accelerator sticking, the dealer would not look at it until they could duplicate the problem so we literally had to smash our foot on the accelator to get the vehicle to accelorate. At times we were trying to cross 4 lanes of traffic and the accelerator would stick in the middle of the intersection at which point the dealer could reduplicate the problem and the throttle plate was cleaned. Approximately 1-2 months later it began showing the same symptoms only this time it is taking longer to completely stick. It was explained to me that the dealer will not be reimbursed for the parts by gm if they can't prove the accelerator sticks first. My question then is do I have to be killed by an oncoming semi while trying to cross 4 lanes of traffic before someone will fix my vehicle properly. My next question is am I the only one complaining about this. Someone needs to take a closer look at this problem and fix it before a fatality occurs. My last question is what causes this problem. I have heard a variety of excuses that throttle plates get dirty, a new car shouldn't be doing that, etc, etc. Help!!!!!( dot number: tire size: 16 )

When driving and upon depressing the accelerator pedal, the pedal got stuck, did not return, causing unwanted and unexpected acceleration. The dealer cleaned the fuel injector to correct the problem.
When placing vehicle into reverse and then placing it into drive on flat surface or on an incline, rpms raced very high, and vehicle jerked forward, leaving skid marks on the road surface. Consumer has contacted the dealer. Please provide any further details.
No summary listed for above vehicle.
Accelerator or throttle hangs up from dead stop, causing the vehicle to lunge upon acceleration - fuel gauge goes to full mark will not move until fuel tank is almost empty - engine has a sound like the valves are rattling after vehicle has set for 30 minutes or more - vehicle has a bad miss in the engine as if it will stop running this is intermittent most noticeably on inclement days - exhaust has a loud hum at 35 to 45 MPH and any time you accelerate to pass or merge into traffic.( dot number: 029056 tire size: p22570r16 )
Accelerator pedal sticks during acceleration from idle. This causes "jack rabbit" acceleration once pedal lets loose. Very dangerous problem in bumper to bumper traffic. Lubricated external throttle linkage without success. Problem seems to be internal where linkage meets engine component.
While driving on a slight incline let foot off accelerator and vehicle continued to accelerate. Dealer worked on it, and replaced cruise control cable and throttle body. Also, driver's side power windows work intermittently up and down. Dealer replaced switch and motor.
When I take off from a stop light or stop sign the accelerator hangs and truck will not go. But when does unhang itself it it takes off in a lunging motion which could be a hazard. It has done this several times and I have taken it to the dealership and was told it was carbon buildup, and that they could not do anything about it.
When driving at any speed the vehicle is accelerating at 2500 rpms when driving or sitting a stop/ at stop light or just sitting. Dealer can't determine the cause of the problem.
While parked with the ignition off, vehicle suddenly accelerated in reverse, causing a minor collision which resulted in minor injuries. Dealer and manufacturer have been notified.
Throttle sticks at idle position at random times. This has been a problem since the vehicle was new. The dealer attempted to repair but said they found nothing wrong. Vehicle is currently at dealership attempting a second repair. Sticking suspected to be at the throttle body assembly, not the pedal. According to shop manual, vehicles with high mileage can exhibit this problem when egr gases cause deposits on the throttle body. Also have noticed multiple tsb's regarding the egr valve. Suspect that there might be a correlation.
In bumper to bumper traffic & using brakes which got hot. Vehicle accelerated out of control. Front end vibrated. Foot on brakes/accelerator pedal at time. Moved to side of road. Waited 1/2 hour before vehicle was controllable enough to drive. Taking vehicle to dealer.
Accelerator linkage sticks at idle speed. Causes pedal to travel too far once "unstuck" high power take offs from stopped.
