Macan 4 multiple simultaneous system failures

[SteveY]

2024 Macan 4. Yesterday operated normally. Today I receive a rash of warnings; chassis error, rear axel steering failure, braking function limited, rear cross traffic alert not available, speed limit display not available, power steering non functional. . . The sunroof is also inoperable. I am dropping the car off at the dealer tomorrow (lucked out as a loner was available). I suspect software / computer issue as the affected system seem to be unrelated. Will keep you posted.

I’ve also had a bunch of random glitches in the last couple days including the alarm going off in the garage and today a trunk emergency release error amongst a bunch of other error messages. I’ll have to take it in to the dealer, I’m also suspecting it sorely needs a software update

Maybe 12v battery is failing. That would also cause multiple issues.

I have owned my macan sport electric just 3 months and 3,000 miles. It is in the shop for the fifth time!! Every issue has been computer, communication, system error issues. Driving the car when system error messages flash across the screen is unsafe and frustrating. After a total of 39 days in the shop so far, I am fed up. Porsche of North America has been a disappointment in resolving the problem. Will keep you posted

I have experienced all of those issues - and still do. The adaptive cruise control turns off, a lot. The dealer said "environmental" because my car was not clean enough (I have a limited water supply, living in the country, and cannot waste water on regular car cleaning). Why did the active cruise control turn off in slow moving traffic, after being OK for 40 minutes?

Charging is very problematic. The Macan takes so long to reciprocate communication with a charger, that the charging station gives up and shuts down. Usually, I have to telephone the charging company and ask them to manually connect the Macan to their charging station. The friendly support people are aware of the Porsche issues in taking forever, compared to every other make of car.

The worst experience was the Macan's reaction to avoiding a collision. I was in slow moving city traffic when an e-bike was ridden across the lanes of traffic, just as I was moving off. I saw the e-bike in time, and jammed on the brake, narrowly avoiding a collision by centimeters. The Macan, in my words, "through a tizzy fit" because the emergency brakes could not work in time to avoid the collision. The Macan totally tried to shut down with the red circle of death telling me to pull over and call for assistance. I could not because I was in thick city traffic with nowhere to park. I limped for a few kilometres to where I could park for ten minutes. Did that, and the Macan agreed to start.

Just about every time I drive, there is a software issue. And, the amount of charge drops 3% to 5% in the first few kilometres driven, every time, severely cutting back on range.

Now - I just ignore everything and continue driving.

On country roads, off the highway, I set the cruise control on anything and just steer. The Macan turbo can take any corner at any speed, other than through a series of depressions in corners (that really sends the suspension into overload, with axle hops). In a strange way, the Macan feels boring. My previous vehicle was an Aston Marting Vantage S Red Bull Racing Limited Edition and it could take any corner at any speed (without electronic intervention) and was fun to drive!

The other problem with the Macan, for me, is that I just cannot find a comfortable seat position. A few hundred kilometres, and my back pain is agony. I had a Cayenne GTS and it was more comfortable.

Just some feedback after 5 months of ownership.
