NHTSA complaint 117564421. Failed component/system. Primary issue is stalling under normal operating conditions. The vehicle is available for inspection. It is a 2024 Porsche Panamera. It is currently with the dealership at Chantilly. 2. The vehicle stalls while I was crossing a highway potentially leading to a collision. The second time it stalled my daughter was in the vehicle, which could have put her in danger and others on the roadway. 3. The dealership could not replicate the issue 4. The dealership will not have Porsche engineering try to identify the issue they are just stating they cannot replicate it while test driving. 5. There was no indication or warning light that stalling would occur. There were software issues that occurred as soon as I received the vehicle, which I had let Porsche know, and that was an additional malfunction which they have stated they have fixed. This would be the second time that they worked on this issue. I would like to note that I purchased the vehicle in November and as of November 22 Porsche has been in possession of my vehicle. They returned it on December 2 stating they had fixed all issues. On December 3 the dashboard warnings occurred again. Therefore, the car was returned to the dealership, and they have had it longer than I have. There is a lemon law in Virginia that states that the dealership has one attempt to fix a life-threatening issue. I believe this is a life-threatening issue that could injure or kill myself and or my family. I believe Porsche is not taking this seriously and because they can’t replicate the stalling, they would like to return the car, as is even though I experience two incidences of stalling across the freeway .
NHTSA complaint 11634734Currently unavailable camera view restricted” The message went away but I’ve noticed it appearing more often
NHTSA complaint 11590839Driving down a multi-lane highway at 70 mph, a 48V battery malfunction warning goes off as well as the yellow check engine light. A few seconds later a ‘coolant’ error alert pops up. SUV loses acceleration with power dropping from 70 mph to 55 mph to 35 mph. Another message displayed on screen warning me to “Pull over and turn the engine off.” Narrowly missing being hit from the back, I was able to coast to an upcoming exit into a store’s parking lot before the car stalled completely.
NHTSA complaint 11536714The contact owns a 2021 Mercedes-Benz GLE450. The contact stated that on two separate occasions the vehicle failed to start on the initial attempt. The vehicle was towed to dealer who diagnosed that the firmware needed to be updated. The vehicle was repaired. The failure recurred a second time approximately 90 days later. The vehicle was towed to the same dealer who diagnosed that the battery needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 13,525.
NHTSA complaint 11509252Wipers are not installed correctly on all 2021 GLEs on the 167 platform. Wipers make excessive noise and fo not effectively clean the windows. Dealer acknowledges the problem, states of is a common issue but has no known way to fix it.
NHTSA complaint 11485393Car shut itself off in rush hour traffic. Slight Smokey smell. Dash light indicating a 48 Volt problem. Got vehicle towed to dealership.
NHTSA complaint 114710322021 MB GLE 450 bought in April 2021, now approximately 8000 miles with two separate events of not starting. Cannot jump. Once 48V battery system updated (3 months ago), required tow to dealer. Now again at dealer with the same issue and recommended for battery change (last time was software update). Very unsafe, happened first time in public garage at night with no start, and second time in the morning when I was trying to go to work. Based on various blogs and class action law suit against MB in NJ, seems like MB is aware of 48V battery problem, and installed a bad batch of batteries. Frustrating to purchase $80000 car and learn that it is not safe at all, with possible malfunction at any time.
NHTSA complaint 11461858Was driving down a 2 lane road at about 55 MPH, and a warning light message appeared on the dash and said "battery no longer charging" then another message that said "coolant overheating vehicle shutting down" appeared. And the car would no longer accelerate. So I had to pull over on a busy 2 lane road and turn off my car and turn it back on, and then the car was working normally again. This could have been very bad if it was on a multi-lane highway. My safety was put at risk. I took the Vehicle in, and they said they cleaned some engine contact points and this was because the car lost contact with the engine
NHTSA complaint 11459441Recall 21V354 has not been completed. They have had since May 14. I have contacted MBUSA twice and they will not give me a completion date.
NHTSA complaint 11442703On two separate occasions recently, the vehicle suddenly lost all power without warning and stopped. Luckily, these incidents did not occur while driving in high speed traffic, and the car restarted once shut off. When it lost power, all warning lights came on at once. After the first incident, dealer "updated the 48v system and esp control modules and The vehicle is operating as designed." The first incident was on November 9, the second incident was on November 29.
NHTSA complaint 11442064I was driving at full speed on the interstate (75mph) when the vehicle died completely. I had only seconds to maneuver the vehicle to the shoulder. There was no indication of a service issue with the vehicle prior to this incident. The car is/was approximately 2 weeks old, with about 500 miles of usage. Vehicle would not restart so I could attempt to get to a safer location.
