For the past few years I keep getting code P2138. I have spent several thousand dollars trying to get my truck fixed. I have replaced the accelerator pedal at least 3 times. Replaced the throttle body. Did a complete rewire. Replaced the ECM and still the dealership can-€™t figure it out. Every time I leave I-€™m hopeful the problem is resolved but then a month or two later I will be driving and then my truck will lose engine power. Someone is going to get killed because of this if they haven-€™t already. Extremely frustrated.

I have had the Tire Pressure indicator that tells the tire pressure of all four tire replaced several times. John L Sullivan Chevrolet in Roseville California keeps telling me that they are wearing out do to use. But the truck only has 70K in mileage and I they malfunction all the time. I get readings of 99 lbs of air pressure. Then the same tire will say 0 lbs of pressure. And it will say 7, then 29 then 18 lbs of air pressure in a distance of 2 blocks traveled. This is a malfunction due to faulty parts in the GM tire pressure reading system and they need to fix it. If I take it to the Chevy dealer, they want to charge me $209 to per tire to replace them and then they still do not work after they replace them Still get crazy tire pressure readings and it warnings flashing on my instrument panel that are distracting and dangerous. It does not flashes every 5 seconds that I have a tire pressure issue and it needs to get resolved. But Chevrolet will not do anything but charge money of there problem with their truck part that is malfunctioning.

Steering angle sensor is faulty. This is an integral part of the vehicle safety systems, including ABS, and traction/ stability control. How can this part be no longer manufactured after only 9 years? all safety controls shut off while vehicle is in motion.

Frequently when driving truck will do some or all of the following things, door locks locking and unlocking, dash lights flashing, stereo coming on and off, electronic stability control turns off, all lights, exterior and interior, turn off and on sometimes staying off long enough at night will scare you, truck speeds up but then sometimes losing power. All of those things happen when the truck is in motion. I drive on the highway every day which is bad when truck does these things. Not a safe situation for me. Then sometimes when you turn it off you hear a loud clicking noise. If you do nothing battery will be dead when you try to start it next time. I can get it to stop the clicking by raising hood I and tapping on positive battery can I let or the mega fuse that is on the firewall. Chevrolet has recalled the 2008 trucks for something similar to this. I

The warning screen shows: Engine hot/ ac turned off, I have been replaced 4 times the temperature sensor. It was the test detected. It worked about 3 months. Later a tech. Toll me, just reset the system by disconnecting a battery pole, works for a while. 2 weeks ago I replaced again the temperature sensor, and and the thermostat. I worked for 12 days, and now I have the same problem, but, even when I reset the it it works for not more than 10 minutes, and the " engine hot/ ac off shows again.

Engine doesn't start. Rare and intermittent. No clicks or attempt to start, lights are on and go off when key turned to start. Nothing appears to help ie moving drive selector, engaging/releasing E-brake, stepping on brake pedal, opening/closing hood etc wait some unknown period of time, more than 10 minutes and it starts as though nothing ever happened. I've looked into it online enough to know others have similar problems but haven't found a solution. Maybe not be as safety related as is needed but I can think of a few scenarios that could be dangerous. Thanks

The check engine light came on while driving and when the codes were ran two codes popped up, P2534 (ignition 1 switch circuit low voltage 2. ignition on/start switch low voltage.) and code P069E fuel pump control module requested mil illumination. When I had the dealer check this they said that the fuel pump control module needs to be replaced, however the VIN number of my vehicle did not match that of the recall that is currently in place (bulletin no. 14515B from January 2015).

At 75mph on toll road at night, suddenly the lights (all external & internal) went dark. Hazard light would not work, engine quit, bell went off (door-key in ignition bell), RPM surged. Was able to get off road and waited 10 minutes and truck started. Drove off, got to 60 and same thing happened. Waited 30 minutes and truck was ok except when brakes applied -door/key bell went off. Dealer had truck for three days and could not duplicate. Went to utube and typed in electrical problems-2009 Silverado and several pages of the exact same problem appeared.called dealer told them to replace the battery ground cable and to check the mega fuse. So far the truck is running ok (incident happened in July 2017) seems like the back yard mechanics know more about how to fix this problem. This is serious, driving at night at 75 and losing all electrics is an accident waiting to happen. The manufacture needs to be held accountable for the poor quality ground cables; this should be a recall!!!

While driving at highway speeds, truck had massive electrical issues which caused the transmission to downshift to 2nd gear. I almost lost control. While this was happening, the door locks cycled on and off over and over as well as the door chimes coming on constantly. HVAC defaulted to full heat from air conditioning mode. Stabilitrack systems showed inoperative as well as ABS system. The rapid downshift from cruise to 2nd gear caused tires to lock up. I almost lost control. If it would have been wet or slippery, I would not have been able to maintain control. The vehicle engine revved to 4-5 thousand RPM, as it downshifted and my speed dropped like I was locking the brakes. I could have been rear ended and the deceleration came on with no brake lights, as it was happening with the transmission rapid downshift. I contacted GM via their chat line, reference [xxx]. they told me it was 8 years old and bought over-seas so I was out of luck for help with repairs. It is presumably caused by faulty battery cables. This condition is reported repeatedly on the internet I.e. youtube amazon etc. These parts are not normal wear and tear components and since they cause massive safety related control issues their manufacturing quality is in question. I want to report this issue to help prevent someone else possibly having an injury to their loved ones because of a known condition that could be repaired with a $125 part. I took it to the dealer buckalew chev in conroe tx. And they said it was the battery cables. I have that invoice. I have the transcript from the initial chat with GM.

Safety bulleting 14515 ' chassis electronic control module internal contamination ' 2007-2014. My 2009 Chevrolet Silverado 1500 is having a problem that the electric goes off and on when driving on the highway after hitting the brake pedal. This is intermittent and does not happen all of the time. It seems very dangerous, sometimes when it happens the door locks go up and down. I talked to the Chevrolet dealer in tempe, freeway Chevrolet, and they stated my truck was not part of the safety recall bulletin 14515 even though other 2009 chevroletr Silverado 1500S were part of the recall. I would think that Chevrolet would be glad to fix it before a crash, sort of like Toyota should of fixed their braking and acceleration problem before so many crashes. Is it true that even if the truck is having the same problem as the recall, which is a safety recall, it may not be covered for it is not listed?

At about 90,000 miles the cruise control stopped working and when it is warm outside the passenger's side door electrical lock will not work. It tries to push lock to unlock position, but only pushes it half way. I have read a lot about these concerns on this model vehicle. Is this 2 recalls? it should be. This is not a cheap fix.

The vehicle was being driven by my son when service engine light came on and I then used my actron scan tool and pulled 3X codes from the computer (ECU) codes related to the fuel pump control module, and trailer brake warning light appeared on the instrument cluster cleared these codes. 2 days later codes reappeared all were fuel pump circuit low, fuel pump module and trailer brake codes. Cleared codes then inspected the fpsm visually removed rear cover and the fpsm was full of water I them dried it out for 2X days in the sun truck ran after reassembly. But 3X days later the truck failed to start this time with computer scan tool in hand I checked the fuel pump pressure, the truck had no fuel pump pressure. I then went to my local Chevrolet dealer and gave them the V.I.N. # to check the vehicle for recalls. Only recall was for safety belt recall which was done in 2009. I found out there was a potential recall for the fpsm on this website. So II inquired to the parts department for this part, it was in stock and $183. I then purchased a new ac delco module on-line for $85 put it on and then found my local shop in town to have a tech come out to re-flash the fpsm so the (ECU) would recognize the new part. I am saving my copies of the bills so that when someone dies from this part failing when it stops the vehicle hopefully I can be reimbursed for another planned GM part failure... sincerely mr.
