Battery Cable Problems of GMC Yukon

We were traveling in our Yukon when all power was lost to the vehicle. The steering wheel lock function enabled before we were stopped. Since there was no power and it is push button start, there was no way to control the vehicle. Our dealer said to their knowledge there is no way to unlock the wheel. Luckily our children were not in the vehicle and no one was injured. The dealer said the negative battery cable is fully intact, but had failed internally. What is more concerning is the fact there is no way to unlock the wheel to steer if this happens. Even at 65 mph.

Started the vehicle after it had been sitting for about 1 hour and the gauges did their regular check sweep from left-to-right, then the following warnings appeared on the driver information display screen: 1) service air bag; 2) service trailer brake, and; 3) service front camera. Afterwards, there were no gauges except the voltmeter (tachometer, fuel, temperature, oil pressure and speedometer were all at resting positions). The driver information screen would not show the gear selector, the mileage or the speed and the warning lights for the airbag, emergency brake, traction control and tpms stayed on. I drove the vehicle a short distance and shut it off, restarted, and it did not make any difference. There was no option to take the vehicle to a dealership for service immediately, because we had a train to catch, so we had to drive it about 20 miles with no speedometer, but we called our GMC dealer and made a service appointment for April 22, 2019 once we parked at the train station. The vehicle was parked until April 21, 2019, and, when started at that time, the instrument panel and driver information screen worked correctly. On April 22, 2019, our GMC dealer (woodbridge Buick-GMC) performed a diagnostics and discovered a b3980 (no environment identifier received) in the history. According to the service adviser I spoke to, this code will involve the relays for the trailer braking and the instrument panel. Also; they told me that the battery cable was loose, so they tightened that as well. Our extended warranty did not cover this and we had to pay for the diagnostics due to our manufacture warranty expiring 2 months beforehand. As of now, this problem has not happened again, but it is worth reporting due to possibly being a safety issue.

While driving the vehicle, the door locks began to cycle, nav system and radio on and off. After stopped, remote car lock inoperative, tried to start vehicle and there was no indication of any electrical power with the key on. . . . I thought is was a dead battery. After cycling the ignition key several times, electrical power came back to �normal� and I was able to drive the car home with my wife and granddaughter. The svc air bag light was on and I took it straight to the GMC dealer for diagnosis and repair. The service adviser immediately knew of the problem. . . . . Bad battery cables that either have internal corrosion or break. $594 repair bill to fix the problem. He said he sees about one vehicle per week with this problem and the issue is well presented on youtube by many videos describing the problem. Substandard battery cables are being used on these vehicles and after a short period of time they either begin the break or have internal corrosion and begin to short the vehicles controlling computers. This is a safety issue as it can occur at anytime while operating the vehicle and should be addressed accordingly. For more information or questions, you can contact me 915-526-1452.

Purchased a used 2008 GMC Yukon Jan. 23, 2010 and approximately 4 months later the first issue occurred with the car not starting in my driveway. I thought it was user error. A few months later coming out of the grocery store went to enter my vehicle and no start, went under the hood and moved the battery cable and it started. Later that night I tried to tighten the battery cable, but it wasn't loose. Approximately 1 month later while driving, the dash flickered and "stability traction" light illuminated with slight loss of power. Got to destination exited vehicle and upon return vehicle would not start until I once again moved battery cable around. The last incident which occurred on August 30, 2010 while driving approx. 15 mph through a residential neighborhood, engine just cut off. Wrestled car to side, put in park and restarted. This was the scariest incident because someone could have rear ended me. I took vehicle to shop GMC dealer and they found nothing wrong. 23,000 miles on vehicle now. Purchased with 17,500.

Battery leak at sidemount positive terminal corroding cable connection and brake line metal to rubber line connection. Dealer says this is not unusual but no warranty applies except on battery. Battery store says this is common with delco sidemount terminal batteries. Corrossion through brake line connection could cause loss of brake fluid and braking. Corrosion in cable could disable vehicle without warning. Battery was replaced with different model having reinforced case at the terminal. Corrosion on other components neutralized with anti corrosive solution, and brake line tested for leaks. Battery cable replaced.
