What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
All four airbags deployed, and I observed smoke that appeared to be associated with the airbag deployment. The front ,side,underside and lower portion of the vehicle sustained impact damage.
My daughter accidentally tried to reverse in auxiliary mode- she had the radio on and did not realize the engine was not on The car went into reverse and she had no brakes or steering to stop the car Mercedes - BMW- Range Roger - Tesla - we have checked these cars and it isn’t possible to do this scenario in those…
The macan can reverse with no engine on and then you have no brakes and no power steering . There is a small window of one attempt according to Porsche to use the brakes but you would need to be a strong large man to accomplish the amount of effort required per the dealership - this was not reviewed at the time of…
The seat occupancy sensor fails and deactivates passenger air bag. A previous recall exists for 2015-2018 but the issue continues to occur in 2021 Macan models: [XXX] Requesting the recall include model years 2015-2021 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The water created a potential electrocution and short of much of the wiring, but the rust contaminated the air quality in the vehicle. Evidence of this corrosion shows persistence for more than a couple of years and the car was inspected twice by the dealer over this time, the most recent a year ago.
Vehicle developed a check engine light and camshaft sensor fault at approximately 48,000 miles. Engine began making abnormal ticking noise and later entered reduced power/limp mode condition.
There was a recall on the passenger sideair bag sensor for previous years but the issue is still occurring in my 2021 Porsche macan turbo. The error code reports a faulty air bag sensor. The recall should be extended to later year models. Thank you
The sunroof exploded outward as I was driving alone on the road. It was a loud bang and sounded like a gun shot. It scared me and I swerved. Luckily, I did not crash, and the sun visor was closed otherwise, the glass would have fell on me and possibly into my face and eyes - very dangerous!
