2019 Volkswagen Golf Alltrack

Several times now, my 2019 VW Golf Alltrack S while driving has flashed a warning saying "ignition switched off" and then "check starter system". I can still apply the brakes, steer, and accelerate, but various electrical systems stopped working, including the speedometer. I've brought it to a VW dealer, but they said they couldn't find an issue. Several places online say that this is an ignition switch issue and that it was fixed once they replaced the ignition switch.

After being in hot sunlight all day(95+ degrees), car started and about three minutes into drive the engine and all electronics died while going approximately 15mph, warning display flashed up on center lcd display that ignition was off, please pull over, and then to check the starter. The power steering turned off so I had very limited steering. The car would not restart, took about 5 minutes of waiting and had to remove the key and reinsert it before it would start again. I was only going 15mph on an empty residential road, so no damage, but if it happened on a busy highway it might have resulted in a crash. Dealer could not reproduce the fail, but read codes that showed the ignition switch was faulty, and they replaced that. The car was at the dealership to look at another issue(the blind spot monitor lights not turning off), and I picked it up from the dealership minutes before this ignition switch issue occurred. They found no issues or error codes with the blind spot monitoring or any other electrical system, the ignition switch issue only occurred after the car was sitting outside in direct sunlight for 5 hours. I believe the heat was the issue, I have found multiple online forum posts where owners of 2019 VWs of different models have the same issue on hot days.

While driving, all vehicle gauges and HVAC suddenly stopped working. Car beeped, and screen said "pull over safely" (or something like that), and then said "Check starter system". Turned car off, and then eventually it turned back on. Same thing happened again, but I was able to continue driving (engine kept running), with no HVAC, no speedometer, no tachometer, nothing. I don't know if turn signals or exterior lights were working.

On July 5, 2023 the electronics in our 2019 VW Golf Alltrack S, stopped working, while that car was been driven on a highway. The following was no longer operational, (while the car was still in motion): gauges such as speedometer, tachometer, fuel indicator and engine temperature; controls such as turn signals, wipers, dashboard and car indicator lights, also the infotainment system, used at that time for driving directions, was no longer operating. The car engine was still running; however, safely pulling to the side of the road was hardly possible, as the turn signals and lights no longer worked. After the car was stopped and the engine was turned off and on few times, the above-listed electronics started working again. Prior to this incident, the car has been driven daily and has not been parked for an extended period of time; it also has been serviced in accordance with the manufacturer requirements. A few weeks prior to this incident, the car was serviced / inspected by an authorized VW dealer. The same dealer examined the car, next day after the incident, and determined that a faulty ignition was the cause of the issues. Replacing that part (under warranty) required few days, as an incorrect part was ordered by the dealer. The loss of key controls and gauges mentioned above, and required for a safe vehicle operation, created a dangerous situation, which should be investigated, in order to determine if design issues exist and require further actions, to prevent such incidents.

Multi-system failure - multi incidents; Dealership has confirm and 'corrected' but several electrical/engine issues persist. Vehicle has been inspected by three VW dealerships (Royal Motor Sales in San Francisco, Serramonte, CA and Kalispell VW in Montana). Several issues were observed while driving - multiple system failure warnings, and also engine failure multiple times. The last time the engine failed while driving 75 miles an hour and there was no where to pull off nor shoulders.

KEY FOB LEFT ON TOP OF CAR WHILE TRYING TO PUT CAR SEAT IN, WHICH ALLOWED CAR TO START (PUSH TO START) AND MOVE, HOWEVER KEYS FELL OFF CAR DURING MOVEMENT. WHEN DONE WHILE PARKED THIS WILL NORMALLY LEAD TO A BEEPING SOUND AND A WARNING THAT THERE IS NO LONGER A KEY IN PROXIMITY, AND TWO BIG YELLOW LIGHTS COME UP ON THE DASHBOARD. HOWEVER, AS THE KEY FELL OFF THE ROOF WHEN THE CAR WAS ALREADY IN GEAR/MOVING, NO WARNING SOUND OR DASHBOARD LIGHT CAME UP (CAR ACTED AS IF EVERYTHING WAS NORMAL EVEN THOUGH THERE WAS NO LONGER A KEY IN RANGE). THIS LED TO A SET OF LOST KEY FOB/HOUSE KEYS AND BEING STRANDED ONCE PARKED.
