Failure Date: 07/01/2014

I started my car and while I was in park the speedometer said 70mph. While I was driving it would register over 120mph. I had no idea what speed I was truly going. This is a scary feeling especially with my three children in the car. I tried turning off the car putting it in drive and back to park thinking perhaps it was stuck, but nothing works. I see this is a common problem. . . Help??.

As I was driving on 95n of college park, MD, my vehicle power seem to shutdown on the highway and the "reduce power engine" message appeared in my instrumentation panel. Fortunately I was close to the emergency pull off of the left lane to get out of traffic. I turned the truck off and back on, and the message went a way. I was able to continue to with my journey. However, just recently, it has done it again, this time my speed was around 35mph. Once again, I turned it off, than on and the message went away and I had power in my accelaration again. This is very dangerous. I'm taking it back in to the mechanic to have them look at it.

I was getting ready to pull out of my driveway and bring my child to preschool when I noticed there wasn't power when I stepped on the gas. Reduced engine power is what I read on my dashboard!!!! I returned to my garage because I was unable to drive him to school. I am very upset!! this looks as if it's an ongoing problem with GMC. I made an appointment to have my vehicle looked at, and I am waiting to find out more about this issue. I will be just as upset if there is a large out of pocket cost. This should be recalled, there are so many others with this same problem, I was just fortunate to be home.

2007 Yukon xl - traction control came on causing a reduction in power while traveling. This is a safety concern that should be addressed by general motors. This is a very serious safety issue that needs to be looked into, before somebody gets hurt or killed. Gm needs to recall their products that are involved.

Wife driving truck to work " reduced engine power", message came on the dash, and also said traction control was disabled. Power was reduced gradually to ten miles per hour. She floored the gas, nothing. Turned it off, restarted it, nothing. Engine light and traction disabled lighted were illuminated. Also the rear mirror temperature display flickers all the time. Drl burn out almost daily. Gmcs have major electrical issues before people start dying. Imagine a car shutting down on you while on the highway. That an accident waiting to happen. The rear wiper works when it feels like working, there is also a message about fixing the ride control. For all the bail money GMC got, they should recall these mistakes they made.

I was driving approximately 65 mph uphill when my engine and traction light came on. My speed was immediately reduced to about 35 mph even though I tried to accelerate. I drove home about 8 miles at a reduced speed because I had my children in the truck and it was raining. I took the truck to a mechanic the next day and he replaced the throttle body. I picked up the truck that evening and as I was driving home the same thing happened again. I took the truck back to the mechanic, the check engine light and tc light was on again however he said that there was nothing wrong. His thought was to replace the throttle body again. Two replacements later, the problem remains.

Driving to work and "reduce engine power" came on. Engine stalled out and would not gain speed. I was in a lot of traffic when this happen and my vehicle cause a incident because of the sudden engine reduced all speed. GMC should do some research about this problem and inform the public of all the dangers these vehicles are causing for public transportation. This is ludicrous that GMC does not have these vehicle off he streets and destroyed knowing that they are putting people lives in danger. I will ever ever buy a GMC vehicle again.

It appears in my investigating this through online searches and forums, there are 1000's of gm vehicles that have had their speedometers quit working and is quite a money maker for gm and their dealerships, since they 'have' to do it so it can be reprogrammed for mileage authenticity! with these 1000's of gm vehicles having faulty speedometers, or other faulty gauges. . . Mine is stuck on 120mph!! definitely a safety issue when u really don't have any idea how fast you are going!! I think this is something they are well aware of, and not because of normal use and wear!! my 2005 GMC Yukon denali would cost $510 + tax and have to b sent away to b repaired. . . . Please investigate this and add this to all the other problems gm is having and let's not put it to the consumer like they have and are doing! thank you!!.

Roughly 30 times since March my 2007 GMC Yukon xl 5. 3 slt has had the dreaded stabilitrack off, service stabilitrack, reduced engine power problem. You can be driving along at various speeds and the error will come on and you will be completely unable to accelerate. Leaving a very dangerous situation for my family. It has happened when pulling a camper and without pulling anything either. Gm refuses to help the many families having the same problems.

The contact owns a 2007 GMC Yukon denali. The contact stated that while driving 15 mph, the esc and check engine warning light illuminated as the engine lost power. The vehicle was restarted and taken to the dealer for inspection where they advised that the throttle body and the vacuum hose needed to be replaced. The vehicle was repaired but the failure recurred at least twenty-five times. The manufacturer was notified. The failure mileage was 134,000. The VIN was unavailable.

Driving 65 mph on the highway and all of a sudden my car loses power. This is very dangerous! the dash says reduced engine power. Engine light comes on. Codes for the problem p0120, p0171, p0174, p0300, p2135. I got everything done that was suggested the codes are gone and it's still happening!! not sure what the GMC dealership is up to but they don't have a clue to what's causing it or how to fix it!.

While driving in the city, my truck was driving fine. Then the stabilitrak came on. When it came on the engine slow down, and almost came to a complete stop while driving on a major road where the speed limit is 55. I was able to pull over and turn the vehicle off. I was able to get it to start and call the GMC dealer, told them what the problem was, and they asked could I bring the vehicle in to see what the problem was. After they service the vehicle, they said that the stabilitrak needed to be replaced. I hadn't even had the vehicle for a full year. Before I left the dealer I asked could I still drive the vehicle, they said that I could. So I continue to drive the vehicle. One day while drive the vehicle, it moved forward while my foot was on the brake and shut off. I tried to immediately start it cause I was behind another car at a light. I was glad that it didn't hit another car. It would not start immediately. Maybe two minutes it started and when I put it in drive and press the gas it took off fast. While driving, the stabilitrak light comes on and the engine power is gone. If I am not able to pull over, the speed will drop below 20 mph. Sometimes the vehicle will take off, with just a little bit of gas. Help am scared that it might take off and hit someone or shutoff and hit someone. This is a dangerous problem, that I feel GMC should look into before some dies or really get hurt.

When driving the vehicle it drives fine but when it gets to speeds around 50-60 it will completely shut off I have to put it on n and turn the key all the way back and then try starting it again. After it turns off the first time then it will start turning off more randomly. I have been reading online and it seems to be a known issue with these trucks around the same year.

Driving on hwy going aprx 65mph. Vehicle said reduced engine power and started slowing down. I had to pull to side of the road. I managed not to be rear ended. This has happened often. It is a potentially life threatening situation. GMC know about this problem and how difficult it is to find the proper fix. Someone is going to die due to their lack of action. It's not safe.

The service engine light and traction control turn on and the information center on my cluster reads "engine power reduced" and "stability system disable", then my speed is reduced and only runs between ten and twenty miles per hour. I have to turn off my truck and turn it back on after a few minutes to continue, but this problem has happened on a daily basis. I think GMC is responsible for this and more similar problems.

While in the middle of driving, the "stability control diasabed" sensor comes on folloed by "reduced engine power" and my vehicle just shuts off. I have been fortunate the 4-5 times it has happened as I have been able to pull off the road, wait a couple of minutes and restart my car. I have already replaced a hub that my mechanic said was causing a "traction control" problem from earlier. I am reading online all of the nightmares and I unfortunately do not have thousands of dollars to keep trying to fix an issue that GMC is clearly aware of. I have 5 kids and frequently drive them around and someone is going to get hurt and I think GMC should take some responsibility.

A friend of mine just showed me a letter he got in the mail that is a recall to fix the reduced engine power code that shows a throttle body needs repaired. . The letter says to bring his vehicle in if it is a gm or chevy model less than 10 years old and less than 150000 miles and they will fix it for free. I contacted gm to see if my GMC was on the list and they told me to take it to a dealer and have a diagnostic done. I have already had one done and the codes keep changing, and from what I have read the gm site and other forums gm does not know what the problem and will not recall it unless they have to, my brother is also a mechanic and had it looked over by our college mechanic shop. Still no relief, I am not willing to spend $5000 and it still not fixed. . So I guess since something like it is recalled and I get into an accident because it reduces power on the interstate doing 75mpg, ill can to take legal action? I can't drive it half the time because of the problem. In the summer it starts with reduced power because its 90 degrees outside.

I was traveling on the freeway at about 70 mph coming from a supervision training class along with a CO-worker and the following sensor lights started appearing on my dashboard: traction control off, stabilitrak off. This has continued to happen on a regular basis. I have taken it to the gm service at least twice and private repair facilities numerous times and the situation continues. It is now 01-28-2014 and the situation continues and is getting worse. Alone with the above issues now the "reduce engine power" light comes on and the engine shuts down. It has become very dangerous to drive this vehicle and no repair facility, gm or otherwise, knows how to fix the problem. I have to drive so this vehicle is what I drive but, it is dangerous and gm needs to fix it or recall for this issue. I need answers quickly I fear this issue is dangerous for all concerned especially when this happens on a freeway!!.

When starting my 2003 GMC Yukon the dash says reduced engine power. . It won't go over 15 mph. . . . It happens everyday! I have to keep restarting it and let it get warm before I can go anywhere. If this happens while I am driving it, and someone hits me I will sue gm, as I have been a loyal gm customer for 35 yrs. . . If you read all the complaints on the web about the same problem then you would definitely issue a recall before someone gets killed.

Received recall notice for instrument panel cluster. Recall would only be covered if instrument panel cluster failed or within 7 years or 70,000 miles. Instrument panel cluster failed exactly as described in recall at approx. 167,000 miles. Only reason we know it failed was a speeding ticket was issued for 58 mph in a 45 mph zone. Car was being driven at 45 mph. Certified GMC service center confirmed instrument cluster was faulty. Cost to repair was $515. 62 plus cost of speeding ticket. I feel GMC should cover cost of repair.

I was driving my Yukon 2003 denali and the error message showed up "reduced engine power". I wasn't able to get the speed up to 30 mph on the highway. I pulled into a parking lot and had someone come pick me up. When I went to pick up my vehicle, the message no longer appeared and it functioned at normal speeds. I am nervous about traveling with my family in the vehicle now.

While driving from chicago to milwaukee on 1/26/11 my speedometer started to indicate very abnormal speeds. My portable gps indicated I was traveling 62 mph yet my Yukon's speedometer read 110 mph. When I reached my destination in milwaukee and turned my Yukon off, the speedometer remained at 55 mph. I immediately googled faulty Yukon speedometers and found a large quantity of sites containing defect information about GMC Yukon's speedometers. I also read that gm supposedily sent out letters to customers. I can assure you that I never received a letter about this. Having 3 small children I would not let something as serious as this go unfixed had I been made aware. I am now at 96,000 miles and see that gm's "recall" ends at 80,000 miles. It would have been nice to have been notified so I could have had this repaired. This is exactly one of the many reasons people have lost faith in gm and other american car manufacturers.
