My car whined and groaned when you turn the wheel so I took it in and had the power steering pump replaced and now my wheel.wont turn at all.upon reading many complaints with this vehicle found it may be the rack and pinion I am.going to have to tow to a different mechanic to see if the new problem is covered under warranty.

Every time I go to the gas station after filling up my truck with gasoline, my vehicle will not start up right away. I have to press the gas pedal lightly in order for it to start up. This just started recently.

It has been since I bought the vehicle... gas gauge is intermittent and cross traffic alerts go off randomly (with no traffic or obstructions) paint has had to be redone leather replaced trim redone etc... the car almost killed me and my children, I'm driving down the freeway at 70mph and suddenly I lost control of the vehicle it slowed down to 49 then 25 lost steering and able to drift to the side before the whole vehicle started shaking violently and I shut it down as I believed it would explode (I was terrified) I called a dealer and they asked if I turned it off and on again ? engine light came on traction control would not renegade and message said decreasing power to engine while it was happening and ABS light on... all failures... managed to get to destination but vehicle was sluggish and jumping gears felt really jerky... 4th start all lights disappeared and although car was still sluggish figured might have been an electrical fault made appointment for dealership told it would cost... parker car drove other vehicle then had to use this one and same thing happened again so took to dealership they couldn't figure out the codes was told had broken engine mount (said it was on backorder as it's been happening a lot) and was sent on my way to see if it would happen again. That weekend it happened again had figured out by then that 5-7 starts it would act up. Took to dealership and left running so they could see what was wrong (failed transmission, steering column block pump sensor etc replaced. Was given a rental GMC by herts and you guess it same thing on freeway all the lights on the dash start lighting up failed traction eas and breaks (super scary brand new only 600 miles on that car) switched out vehicle for a safer car (Toyota) I'm unable to check more boxes but speed and control were also affected

A few days before my girlfriend left with the SUV out of state I noticed the electric door lock (only on the passenger front door) was back to manual. Than the same day of trip it started working again, but on her way back she called me to say the light came on for service stabilitrak, and trac. Control off. It was also effecting the steering wheel making it jerk while going over 60mph on the highway making it a safety hazard. After reset jt was fine, but very alarming to continue to drive this SUV for years to come knowing it could pop up and safety issue at any given time. This needs to B addressed asap! sounds like a ground issue. SUV is 4 years old, and rust and corrosion free. Maybe GM made an error with interior mounted modules. Also the vehicle was coming out of a slowing traffic area on highway at the time (construction zone) when tring to catch back up to speed the vehicle reduced power. (limp mode) this seems to B a very common problem.

Ist time-car stationary-started car and it started shaking-tractionary control warning came on-turned car off-waited a few minutes and turned it on and it was fine -the next day after driviing 250 miles it happened again after stopping for a toll booth-the car shut down with the same warning-after two tries it started and we drove to a Chevrolet dealer and they replaced the throttle body

At just under 1 year old the rack and pinnon went out. Replaced under warranty. Then at just over 3 years old it went out again on top of that for the last 9-12 months the engine will rev up and accelerate on it's own after it will chug for a bit then the sensor stabilitrak warning comes on then it will say traction control off then it will say its back on. I have also had it where it will looses engine power and you can barely get it to go when pushing the gas pedal. It's done this series of events about 10 times. It happens when driving, when in park, and while sitting at a red light. No rhyme or reason to it. But it is pretty unsafe when a vehicle will accelerate on its own driving anywhere! not to mention that a rack and pinnon should not go out 2xs in less than 3 years let alone on a vehicle that cost 45,000+ that was purchased to order brand new! these kind of costly repairs might I mention aren't covered under their power train warranty, though rack and pinnon is part of the steering component. Also this summer at less than 4 years old the ac quit working so I went in 90 degree temps with a baby and no ac until we had a chance to recharge it with refrigerant.

On 15 plus occasions, while the vehicle is stationary, in the parking gear and running, the front end will start to vibrate mildly, increase in intensity and then the traction loss light illuminates, a blinking engine light illuminates, "service stabilitrak" and "service traction control" messages appear. Then traction contol off appears, followed by an audible loud click and vibration ceases, messages disappear and lights turn off. Once while vehicle in drive and being operated on a roadway, I pulled right at an intersection to have this same sequence happen during driving, resulting in an almost complete loss of power and acceleration and a near accident. The sequence was identical and once the errors cleared the vehicle accelerated rapidly and forcefully. I have documented multiple occasions on video while stationary over a multi month period and have furnished those documents to my local GMC dealership which has failed to repair this issue and today returned my vehicle to me with an apology for not being able to remedy the problem. They claim that the vehicle must exhibit this behavior in their presence to warrant a fix. The vehicle is under an extended warranty that clearly covers these problems. I would be happy to email the videos, but they are not in the supported format and likely larger than 5mb.

While driving in heavy city traffic, my warning lights came on for "reduced power", 'traction control" malfunction, 'stabilitrac and ABS lights came on. Power reduced to 25mph. I was close to the dealership and went there right away. The service writer told me I would have to wait at least 2 to 4 hrs before anyone could look at. My mileage was 36,432...432 miles out of bumper to bumper warranty...he told me the charges for diagnosing would be $130. I agreed. Then he explained that the the low hp fuel pressure/purge solenoid was stuck open, dianose codes were PO191 and PO496, they replaced a high pressre fuel pump, R&R intake plenum to replace fuel rail pressure sensor and replace a purge control solenoid. Cost to me was $1,760.51 ($866.06 labor- $820.43 parts -$30 misc.charge-$82.29 misc.discount- taxes of $126.31. I don't understand why they couldn't be more lenient with mileage on warranty. I purchased this vehicle new from them and have completed all my service work there. This was a scary situation in noon rush hour traffic without any roadside pull off at the time. Could there have been a defection fuel pump? I was told by service writer "if you had driven any further more damage would have happened to engine block".

When driving stablitrac, ABS, all wheel drive fails giving alarms on the dash. SUV starts so shutter and loose acceleration. If the car is stopped and shut off it will clear. When you start driving again it will randomly do it again, such as when you turn a corner or pull out to pass someone. I has happened a couple of times. The last time was worse. I almost got hit because it lost power. Looking on line it looks like the same problem that other GMC vehicles have a history of.

Approximately 2 months ago, the vehicle shut down in the middle of high speed traffic. Several warning indicators appeared (e.g. "stabilitrack off", etc.), then the vehicle immediately shut down. Propulsion stopped and the vehicle slowly came to a stop. Luckily, my wife was able to steer off to the side of the road safely. It was towed to the dealer, although it was able to restart. The dealer had fixed it, then returned the vehicle to us. Two months later, the identical thing occurred; same error messages followed by the vehicle shutting down, in the middle of driving it. We took it back to the dealer, and a different problem was diagnosed (with the vehicle out of service > 2 weeks this time). We have lost confidence in the vehicle, and feel it is unsafe to drive.

Service stabilitrak--traction control off! message, then car ran rough and lunged on acceleration. This happened at 5,000 miles, repaired at dealer. Again about 12,000 on a trip and reset itself. Now, at 20,000 miles sames message and is at the dealer being repaired. This is a safety hazard. Please investigate this.
