hey everyone I hope you are still watching this forum — I have a similar issue but not quite the same with an 07 as this one here: 2007 Weird Electrical - VSA & /!\, AC stops blowing...
for a couple years we would very occasionally get an issue where we couldn’t start the car at all OR the lights for the transmission would blink or show weirdness (P, N, P, R, 1, 2). Every time, just moving the shifter up and down would solve the problem. Also our Verizon HUM reported P1717 and Emissions from the OBD. I read in the forums that it is very common for the transmission range switch to get corroded. Mechanic tried to get a new oem switch for weeks and couldn’t, so I ordered one from amazon (not oem). All the above problems went away, but a new weird problem happens intermittently now:
1. VSA, /!\, and ((ABS)) lights come on randomly; I think they only turn off again if we turn the car off and back on then they will go away after several seconds usually
2. sometimes but less often the sliding door will beep instead of opening even when in Park and doors unlocked
3. I noticed that sometimes the front wiper interval setting doesn’t behave normally - the shorter duration setting in interval mode should be constant but has about a five second delay and the longest will be about 10-12 seconds; but then sometimes it works normally — this happens sometimes even when the VSA lights are off
3. the HUM still reports P1717 and Emissions frequently, but now also also reports U0155 at the same time as those.
Maybe a side note is that in the last few years we replaced the steering wheel coil to fix the radio volume buttons, and also ended up replacing the MCU to fix an issue where sometimes the headlight low beams would randomly turn off (but high beams would keep working and bulbs were fine). But the timing of this current issue is not correlated with any of those and it started after the transmission range switch was replaced.
FWIW I’m in Northern California where it is often 40s and humid in the mornings and then sunny and dry later in the day. And no the car has never been in a flood luckily (I’m the original owner).
So I am thinking maybe the non-OEM transmission range switch is bad and I should replace it again, but maybe something else is going on?
