While driving east on i-40 in north carolina, my power steering catastrophically failed and i had to use all of my arm strength to steer the vehicle. The section of i-40 where this event occurred is extremely curvy (near the haywood rest area) and there is no margin for error. If i had not been alone and totally concentrating on my driving, i could envision a severe accident as there were cars all around me. I managed to drive the vehicle to my porsche dealer in columbia, sc for repairs. They found multiple faults for the steering torque sensors and determined that the electric steering rack was faulty. They replaced the steering rack. Prior to this event, i had complained to the porsche dealer about rubbing noises in the steering. The dealer replaced the steering shaft but the noise came back.
While driving at approximately 40 mph, traffic began to slow. When i attempted to slow to match traffic conditions, my brake pedal offered almost no resistance and sank to the floor. The car did not slow. I pumped the brake pedal repeatedly but it had no connection to the cars brakes. A vehicle collision occurred as a result as i coasted into the car ahead of me.
The specific concern pertains to the routing of sunroof water drains from the roof to the wheel well of several porsche vehicles. In this case, the rear water drains are routed directly over fuses and other electronic components within the vehicle. One of the electronic components affected, a park assist control unit (part 95b 919 475 l), controls multiple vehicle safety functions including perimeter sensors and the backup camera. When this unit fails, the backup camera is blank and perimeter sensors that beep to notify the driver of potentially hidden objects (or people) close to the vehicle do not function. Such failure may jeopardize the overall safety of vehicle occupants and other road users and may affect safe operation of the vehicle. This park assist control unit has failed in my porsche macan on three separate occasions due to corrosion of the terminals. The porsche orland park (illinois) dealership where i took my vehicle for repair stated that the corrosion was due to leakage from the sunroof drain onto the unit. After the third failure of this unit due to corrosion, i contacted porsche north america customer support. I was told that the corrosion of the terminals and subsequent failure of the park assist control unit was due to clogging of the sunroof water drain, causing “pooling and draining to places where it can cause damage. ” although other electronic components directly adjacent to this unit have never had similar corrosion, there has never been evidence of water leakage inside the vehicle, and i regularly test the drains and have found no sign of blockages, i accepted porsche north america’s explanation. They stated that “park[ing] a vehicle outside” or “driv[ing] where there are many trees” may exacerbate the issue. Unfortunately, subsequent concerns i raised regarding the tendency for these drains to clog at any time and porsche’s decision to route a water drain in such close proximity to electronic vehicle safety systems were ignored.
As i was stepping on the accelerator, i heard two pops and somehow the car lost its torque/pull. Check engine light came on. Went to the dealership and they said the high pressure fuel pump is broken and it cracked. There seems to be a recall for 2015 to 2018 models, but not 2020 models. My car only has 13000 miles too. Safety wise, i felt endangered since the car couldn't accelerate properly.
It was noted there is fogging, spiderweb type cracks, and discoloration on the inside of each headlight lens. It was discovered through conversations at the dealership and online research that a chemical reaction between the factory lens coating and the gas emitted by the headlight bulbs was the likely cause. Lumen output has gradually decreased as the issue grows worse and both lenses become more opaque in appearance. The car is available for inspection. We are asking nhtsa to investigate this issue for the following reasons: 1) this is a growing safety issue as lumen output is steadily decreasing 2) this is unrelated to regular service/maintenance or any culpability on behalf of the owners 3) absent replacement, this issue cannot be corrected by the owners 4) it has been reported to be a growing issue among numerous porsche macan owners. I asked porsche if it was covered under the warranty, they stated it was not. They did examine the car. No warning messages.
My passenger occupant detector is faulty and unable to recognize if someone is sitting in that seat, therefore the airbags will not deploy in case of an accident. There has been already a recall on this item for my car, but obviously my car was is affected and my vin isn’t included. So i think it’s needs to be reassessed
Driving north on interstate 95 near stafford, va and took exit for lunch. Restaurant was right at exit and we entered the parking area. Went to turn and the steering was frozen. Caution light said power steering malfunction and steering could only be turned slightly with maximum effort by driver and passenger. Managed to move car to parking area. Subsequently towed to porsche dealership in arlington va for repair. If this frozen steering had occurred moments earlier on i95, we would have likely crashed with the vehicle suddenly unable to be steered. We were terrified and believe our lives were in jeopardy. The dealer identified the problem as a broken/defective electronic rack & pinion steering unit. Vehicle has approximately 20,000 miles and is always garaged. The failed parts will be available at the dealer when replacement parts are received. There were no warning lights or indication of any problem prior to the event.
Front brake hoses rub between the steering knuckle and the suspension fork resulting in hose rupture and brake failure. Wear on the hose is visible on both sides.
Fuel injector connection at fuel rail is spraying fuel onto the engine, fire hazard.
A recall was issued by porsche on 2015-2017 macan suv's for front airbag deployment issues. The recall code was ah02 safety campaign #17v133000. I contacted porsche because my fault indicator for the front airbag lit up on my dash. I was informed that my vin was not included. I asked if they could check if my airbag had an identification number and if it was in the batch under recall. They said that they could not look it up. My car was a custom build and may have come down the line at a different time than other stock builds which may have impacted the timing of the airbag install. Either way, my car was in the date range and has the airbag default indicator on therefore it should be covered. I had it tested for $265. 00 and they covered themselves saying that it was an airbag control unit and seat pad fault code b102204. What's the difference, the recall covers faulty airbags and mine is defective and they won't cover it. Please give me some guidance as to what my available options are at this point.
