The GMC Denali SUV has been in production for quite some time. Despite some criticism, it’s a relatively well-received full-size SUV. However, like most famous vehicles, there are models of the Denali SUV that used vehicle buyers should avoid. Fortunately, this GMC SUV’s list of bad models is pretty short compared to many of its closest rivals.
Here are 3 of the worst GMC Yukon Denali models.
The 2015 GMC Yukon Denali
When it comes to used GMC Yukon Denali models, the 2015 SUV is considered one of the worst. The biggest problem that has been reported around this Denali SUV model is that it has starting problems due to the failure of the anti-theft system. This is a big problem as it could strike at any moment and leave owners stranded. The solution is reportedly to replace the ignition switch, which is not expensive.
Engine failure is another problem that has been reported on this GMC SUV. In this situation, misfires are caused by the fuel injectors getting stuck in the closed position. This is reportedly the result of certain fuel additives and not necessarily a failure on the part of the vehicle. Most situations require replacement of the impacted injector.
There is also a problem with the throttle position sensor on this used GMC Yukon Denali model. With this, the vehicle may experience reduced power. It also causes the check engine light to come on. As with the other problems, the system may need to be replaced to fix this.
2007 models also have problems
The most complained about problem with the 2007 GMC Yukon Denali is that the upper dashboard tends to break. According to RepairPal, this mainly affects people who live in warm climates. Another major problem with the 2007 GMC Yukon Denali is that the power door actuators could fail. This failure causes power locks to work slowly or shut down altogether.
In addition to GMC Denali SUV power door locks, door handles also tend to break. Door handle breaking is true for interior and exterior. Of course, the only solution would be to replace them. Fortunately, this would probably be fixed by now on most used models.
The 2001 model is a used GMC Yukon Denali with issues
The 2001 GMC Yukon Denali has many of the same problems as other less-than-great models. However, one of the big uniques is that the intake manifold gasket can leak oil or coolant. This could also cause coolant and engine oil to mix, which is never a good thing as it could cause engine damage. An owner would have to replace the gasket to fix this problem.
There are also issues with the speedometer on this GMC Denali SUV. For some unknown reason, it starts working erratically. Erratic speedometer is a major problem as drivers need to know their speed on the road to be safe. Most other 2001 GMC Denali problems are more inconvenient and have less to do with mechanics.
The GMC Denali SUV is primarily considered a pretty good vehicle. People love it and use it as a valuable family vehicle. However, buyers should avoid these used GMC Yukon Denali models.
