Electrical system: 12v/24v/48v battery: cables
- What is wrong
- Vehicle description: sport utility vehicles. Some of these vehicles were built with a misrouted positive battery cable assembly that could come in contact with the steering shaft universal joint.
- Risk
- Over time this contact could cause a wear-through of the cable assembly convoluted conduit and cable insulation exposing the wire core and resulting in intermittent electrical shorting. This could result in erratic movement of the voltage gage, total battery discharge in a few hours, or the cable insulation and conduct could ignite if enough current is discharged at the point of contact, resulting in an underhood fire.
- Remedy
- Dealers will inspect the positive battery cable for proper routing and re-route the cable in necessary. The cable will also be inspected for wear of the conduit and cable insulation, and will be replaced if necessary. Owner notification began april 23, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact gmc at 1‑800‑462‑8782.

Alleged failure of 2nd row seatbelt alr
The automatic locking retractor (alr) is a feature incorporated in the subject vehicle for locking the webbing to properly secure a child safety seat into a vehicle.this pe was opened based on a gm technical service bulletin stating that with certain child safety seats the webbing may not remain locked.there are no complaints in the odi database and only two complaints to gm.gm's instructions state for the final step in using the webbing lock feature to push and pull the child restraint to be sure it is secure. If the alr is not locked, the user would be fully aware of this condition prior to completing proper installation of the child safety seat in this vehicle.this investigation did not uncover any complaints of the alr inadvertently unlocking while the vehicle is in motion.the emergency locking retractor (elr) feature remains available to lock the retractor in a crash.a safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.see attached summary for additional information.

What 2001 GMC Yukon XL Denali owners say
Most recent owner complaints, unedited.
Vehicle rolls while in park. Had parking pawl replaced, problem persisted. Problem is more obvious the greater the incline. Vehicle is not freewheeling but has some resistance.
Tl* the contact owns a 2001 gmc yukon xl denali. The contact stated that while driving at approximately 15 MPH, there was a grinding noise emerging from the front end differential of the vehicle. The vehicle was taken to the dealer and the diagnosis was that the front differential failed, but the dealer would not repair the vehicle and informed that the vehicle needed to be inspected by a transmission specialist. The failure reoccurred on three occasions. The approximate failure mileage was 200,000. The VIN was not available.
(recall 05v‑379) ABS light has been coming on intermittently for about 4 years now. We have taken to numerous mechanics to no avail. Now after looking into recalls, I find that there actually was a solution, but we were never notified because we don't live in the correct area of the country. But we do live close to the affected area. I purchased the car used only 3 years after it was made. This vehicle could have been in the affected area prior to our purchase. We would like to be included in the recall. My teenage daughter drove this vehicle to school and dropped off our 8 year old to school for two years. This recall should have been expanded so that I was aware of it to keep my family safe.
We were traveling north up the saw mill parkway from bronx ny. This parkway is two lanes with 3-4 lights depending where you get on, so I had 3 lights going north. At the first light I notice the brakes were week. Second light had the same no pressure brake peddle, and then the third light I had no pressure on the brake peddle couldn't stop at the red light and had seen the cars coming from the left into the intersection so that made me swerve hard to the right and finally came to a stop. The right front brake line blew and fluid was leaking all over. I had both of my daughters, brother in-law, and a friends son in the truck going to a family party in connecticut around 12pm.I had a couple things going for me other than being lucky, a good driver and knowing the highway very well. I made it to the mechanic shop and saw that all my brake lines are rusted up that the mechanic didn't want to touch the others cause they might be very brittle and will break very easy. This truck is not my main vehicle and is in very good shape till I looked underneath.
Coming to a stop sign the brake line blew out on the left rear resulting in the truck not stopping and rolling through a stop sign. Had there been a child on a bike, a person walking or another vehicle coming there would have been an accident. Upon inspection by a mechanic informed me that all my brake lines are rusted out and need to be changed. Im still waiting for a quote but its said to be over $1500! Gm should be accountable and these trucks should be recalled!
While driving my 2001 denali xl my brakes failed and was fortunate that I was not in traffic. Once I crept home I was able to see the under carriage and there were large amount of corrosion on all the equipment. Car is still laid up until I can afford repaired.
I was driving down a highway at 65 MPH when I began to smell smoke. At first I thought that it was just oil spilled on exhaust system. Then the smoke got worse and had a terrible odor. I looked down at the center console and smoke was coming out from around the edges and the ash tray area. I started looking for a pulloff as I was on a country road. As I found one fire started coming up through the gaps. My first thought was that I had a fire that was going to destroy the vehicle. So, once I was stopped I looked for my fire extinguisher but couldn't find it and then I remembered that I had bottled water in the vehicle. I grabbed 4 of them and went back to the drivers side and began to pour water down through the opening in the console that had been caused by the fire melting it. The fire was put out quickly. I then put on gloves and removed the top part of the console that had been mostly destroyed by the fire. In looking into the bottom it appears that small bits of paper, receipts, etc. Had fallen down onto the wiring harness below. My guess is that since I had plugged my xm radio into the cigarette lighter it had heated up the wires which had heated up the papers until they began to burn. I consider this a flaw in the design of the console, the cause being the cracks in the console/ash tray which would allow paper objects to fall onto the wiring harness below and cause a fire. The fire melted about six inches of insulation off the wiring harness and the wires touching each other resulted in fuses being blown. The vehicle is still drivable but as of this writing does not have overhead lights and dashboard lighting available & their is an intermittent ignition issue. I haven't been able to find a replacement wiring harness but suspect that when I do it will cost an arm and a leg. I am trying to repair the wiring by reinsulating each wire and then re-bundling them.
I recently noticed that my spare tire was missing. I took it back to the sear auto center that has been servicing it. When they looked under the car they said that it was common for the yukon spare tire cable to rust and snap off. So I lost the spare tire, spare wheel, and cable system to hold the spare under the vehicle. Not sure where or when it happened, but it was in the last 2 years. Just found out about this complaint service. Have also had to replace the brakes and rotors a number of times (an excessive amount), and have had to have the A/C unit repaired twice. The first time I was told that it had the wrong control head. Also, whenever I hit a bump I momentarily lose power steering.
As vehicle is slowing to a stop, the ABS engages lifts the brake pedal, essentially allowing the vehicle to roll forward, and requiring a quick reaction to strongly depress the brake pedal to stop the vehicle. This is caused by a faulty and corroded ABS speed sensor, which has been recalled on these vehicles from 2002, but the recall does not include the 2001 year. Another known issue is faulty ABS modules in these vehicles which turn on the dashboard brake and ABS warning lights periodically although there is nothing wrong with the brakes or ABS.
