How about electrics, HVAC, other systems? Thanks in advance....:thumbup:
The electronics are basically shared across the rest of the modern Porsche line up and are relatively problem free. The window switches break on a bunch of them if you treat them poorly, they had a recall early on for the seat occupancy detectors and since doing those, I think we've seen a few fail, but not much else that wasn't taken care of by Porsche during their roll out whether it was through recalls or campaigns.
The biggest issue is the PCM3.1 that is fitted to vehicles made from 15-17. I believe I have the change over year from the PCM3.1 to the 4.0 correct. The PCM4.0 is far more reliable than the earlier units and less prone to the issues that the 3.1 system had. The 3.1 had majors issues with freezing a rebooting and some would get to the point where they were essentially non fucntioning. The maps are also outdated at this point with the newest map packages available being a few years old. I would really recommend a 17 and up for this reason.
The HVAC systems are generally problem free, I've seen one or two with leaking a/c lines, but this was on early cars and the line got updated later on. The later cars did switch to R1234yf which they changed over to sometime in 17 so you just need to be sure that a qualified shop services one of those systems if there ever is an issue.
The chassis on them seems to be pretty tough, we've seen very few issues with control arms and ball joints despite them using the Audi 5-link set up. They seem to be more than up to the task. Wheels bearings we have seen fail somewhat frequently, both front and rears. The rears are a total pain to replace compared to the fronts. We have seen a few failed air compressors for the air suspension system also, but I would still pick the air suspension over the steel springs. I just like the functionality of the air suspension though.
Transfer case failures are definitely an on going issue with them, not nearly the epidemic that the E2/92A Cayenne's suffered, but all of them are getting replaced with stronger units when they are replaced.
Those are the major issues that I can think of off the top of my head. Overall I would say they are decently reliable little SUV's.
Thanks for the info. Very informative
How about the 2019's V6 engine? In 2019 they changed the engine out. I believe its the same engine in the SQ5/ S5 /etc....
Any comments?
You mentioned that the chassis has been heavily modified - what kind of mods did they do - just out of curiosity.
Yes the current engines are all related to the Audi line up. The S gets the 3.0 single turbo engine while the turbo will come with the 2.9 twin turbo set up. The 3.0 is still somewhat fresh having its debut for Porsche in the 2017 Panamera. They are now out in much larger volume in the Cayenne, but generally speaking in my experience have been trouble free. I will say that I liked the character of the Porsche built V6 over that of the Audi based engines, but Porsche's hand was clearly forced on this. They are still a good power plant and are well suited to the vehicles that they are being used in though. Plenty of power and pretty smooth power delivery also.
The chassis was modified from the Q5 in a few areas. The rear of the vehicle where the subframe bolts in had to be reinforced to handle the extra power and larger tires that the Porsche has. The front has reinforced impact absorbers, a transverse strut for rigidity and it also got a new transmission tunnel bridge. They also use more rigid subframes and spec their own suspension bushings to suit their desired needs for performance and handling. The braking packages are also specific to the Porsche's with the exception of the base model. Porsche designed their own uprights for the front to accommodate their brake calipers and rotors. The rear is unfortunately a sliding single piston caliper and Porsche really couldn't do much to fix that. This is most of what they list as changes from the Q5 it was developed from.
Awesome post! Thanks so much for the info, very informative indeed. I mean seeing some of these Macan S's currently at 36-40k seems like they're quite the bargain if you want one of the best handling and fairly fast CUV's out there, that is also a Porsche! They'll be big bargains as more continue to depreciate and more available. I'll be watching them!
The real gems are the GTS models. Definitely the best of the Macan lineup in my opinion. I agree with them becoming good bargains and seriously think they are the best driving of all the small CUV's that I've gotten my hands on. The interior is really a nice place to be too.
