general problems of the 2008 GMC Yukon

Intermittent electrical issues. Doors locks and windows don't always work. Sometimes when I shut my car off it dies. Like I can't turn it back on. Running boards don't go up, can't lock it, nothing. Dead. Then 15 minutes later it's fine. Sometimes when driving, it's like it's cutting out, not getting enough power or different warning lights will randomly flash. I just never know when it's going to be working properly. I'm just afraid something will happen while we are driving. We also use the Yukon to tow a trailer. I need to be able to depend on it. The shop can never duplicate the issue and they just look at me like I'm crazy.

I have a 2008 GMC Yukon slt that I bought in Feb of 2015 with 94,000 miles. I have serviced it regularly from day 1 and even paid it off in 2. 5 years. As soon as I paid it off, the very next month, my engine started making a weird noise once in a while w/ no check engine light so no one could tell what was wrong. At that same time my "service stabilitrak/service traction control" would ding about 40 times in a row. I serviced the 2 and it did not help for more than 2 days and it started again. This time the check engine light came on codes were for new plugs and fuel filter. Still didn't help. Then my engine blew! got that replaced and it still to this day is doing same thing! so, like the 330 others, we have a major safety issue that no one cares to address, and I'm done trying! if this man are having the same issue it's a gm issue! I'm copying the NHTSA and my atty general for help. Please click this link and read 330 complaints about the same exact thing and youtube has people actually stuck bc their car died. Mine did not ever die but it sure feels like it is and . It happens every single time I drive my Yukon! please help us! I'm on unemployment and cannot afford anymore repairs. . Read more...

While we are driving on a freeway the car suddenly stop and will have a "stability lose control" message on a dash board. The car will stop momentarily and then it will run again after we start the car. The car has no power at all once it stopped. It happens a lot so right now we're not using it due to safety issue. A big safety issue because we use this to travel with family. I brought this to the mechanic but they don't seem to find what's wrong with it. They did a diagnostic test but they did not get an error message at all. Engine light is not even on.

Takata recall. . . Electrical is always messing up. Always fuel emmisions system light, which then messes up the radio that shuts off and on and gets warm, signals then do not click. The struts and shocks give me problems. I have spent a lot of money fixing one thing after another. This SUV is my means of transportation with my family of 8. I feel it is unsafe to be driving. The truck is affected with driving in a street, highway or making a turn.

The car flashes reduced engine power, stabilitrack off and the car can barely go 30 mph. The engine runs very rough when it is doing this also. My code scanner displays code 641 which is open 5volt reference on bank 1. It does this more when the weather outside is warmer or the car has been sitting still while running. On more than one occasion it has happened while pulling out into traffic causing near misses and other times while driving down the highway. Just yesterday it did it 20 times in a four mile stretch. This car is no longer safe to drive.

I bought this SUV from legends auto sale. After I bought it, I notice the engine bay was real rusty like its been in water or driven over lots of water. I didnt get a car fax at time of purchases but did car fax myself , and it appeared that vehicle is from new orleans. With all the dirt and grim coming out of vehicle its diffently from new orleans. So far I replaced new pads and rotors, master cylinder, brake switch, new spark plugs and wires. The problem occurring now is that my trac light and abs light will come on after half hour of driving and car seizes up and I'm unable to accelerate. I would have to shut off engine and let rest for half hour to an hour before lights goes away and I'm able to move again. I'm not sure but it might be due to it being in the flood thus causing corrosion and rusting in all parts of vehicle. I don't have documents on me at this time as I misplaced it but can get it again and upload image.

Takata recall - I have been trying to get this repair for over a year. Not sure how to handle this as the dealer says they do not have any.

While traveling on the interstate at speed (70) the stabilitrac light came on and reduced engine power message displayed. The rpm's went over 4k, then the Yukon slowed in traffic and I had to pull to the side before being run over. The accelerator was unresponsive at that time. I turned off the engine, waited about 5 minutes and then resumed driving using '3' to engage transmission instead of 'd' the check engine light remained on, but I made it to my destination 2 hours away.

This is twice that I've received the p2138 throttle body sensor code, which causes reduced engine power and has subsequent issues around stabilitrack/awd. The first time was in the middle of an intersection, we limped out of the intersection at 3 mph. Today, my wife limped home from the store. This is extremely frustrating and should have been recalled a long time ago!!.

Have never been contacted when the parts were availble or when the vehicle coould be brought in for the recall corrections.

Was waiting for a red light to change and suddenly my dashboard lit up saying it was reducing power to the engine, disabling stability control and something else. . I was not able to drive the car for for 2 hours after that. . . I. Got the car towed to my house and when I went back to fallowing morning the car started with out the engine light on. . 2 days after the same thing happened while driving on the highway at 65 mph, it was a scary experience since the car reduced power very fast to 20 mph. . Almost got into an accident.
