sorry for this long post - but I'm getting furious and I want to get all of your thoughts and document mine-
The check engine is back on on this (felling not so) new SUV for the 5th time is as many weeks of ownership, with only 1700 miles on the odometer. Incredibly, when we're done with this repair, more than 15% of those miles are going back and forth to the dealer's shop!
I don't fault the dealer at all, Volvo hasn't given them a fix, but I'm not driving around a new car that has a check engine on. The dealer has been sympathetic and appears to be doing all that they can. I don't feel bad for them though, they're getting paid by Volvo for this warranty work and loaners. I'm thankful that the dealer is on the way with a loaner (I'm 30 miles from the dealer) and to take my car back to the shop.
The first trouble was the evap hose that needed replacing after starting the car the very first morning I owned it with under 100 miles on the car. Then the check engine light has been on another 3 times (at about 100 miles, 700 miles, 1400 miles) for the BECM-P0D1F62. This 5th time I assume will be the same battery ecm error, but I have no way of knowing and I would be a fool to ignore the generic check engine warning on a new car that is already problem ridden.
I'm thinking this part bit out here as much for my own notes as I am for feedback from all of you:
Supposedly Volvo told the dealer to tell me that I should "just" restart the car a bunch of times to make the light go away. I've not been successful in making the light go away with over 15 restart cycles. It did turn off one of the times after driving home after the light first appeared, but other than that, it's stayed on until reset by the dealer. I'm not off-base that requiring me to "reboot the car" over and over until the warning goes away is unreasonable right, whether that works or not?
Another note and question for your input
: I factory reset the head unit last week, to fix a Care Key issue (also a software bug). The dealer hinted that the week 16 release of 2.8 for Volvo's AAOS is going to address a lot of issues, but I feel like this is a software issue on a module vs the head unit. What are your thoughts, does Volvo package system monitoring software updates in their AAOS updates? I expect infotainment to be separate from mechanical/monitoring/cam/etc.
I'm no statistician, but I do know a LOT about software, it's a big part of what I do for a living. If this is a software error, how are they not seeing more 2023.5 XC90 T8's with this? Supposedly, I'm the only one.
If there's a software bug, it's either going to hit a lot of cars with the same hardware
(mechanically T8's are essentially the same short the surely insignificant here potential differences seats, audio, heads up, etc) or there's specific / defective hardware that is triggering a software bug
. On that second part, a software bug might only trigger with certain lot numbers of a specific piece of hardware. Maybe there's a variation of a chip on a module that can incorrectly report whatever this is and it needs to be coded to be ignored. ---OR maybe it is bad hardware.
Volvo says it's software and not the BECM. I cannot understand why they would try replacing the BECM to start. My bigger fear is that I've got a bad battery somewhere in the array,
it'll be ignored just long enough for me to go out of lemon law range and they'll say it's not a warranty item.
Lemon Law thoughts:
I really really really don't want to lemon law this thing, but this will be the 4th time back in the shop for this same problem, 5th overall. In my state, after 2 repair attempts for the same problem, I can send a demand letter and if they don't fix it after the 3rd time, it's a lemon. I bet Volvo will try to claim that they didn't try to fix it, no repair attempt was made. It feels like an easy argument, I gave them the opportunity to fix it. Claiming ignorance or an inability to fix a "known problem" on their product should not reasonably exempt them from the lemon law, otherwise after the 2nd try they just say they don't know how to fix to get out of it.
Also, sadly after only 5 weeks of ownership, today (Saturday) will be my 11th day that the SUV will be in the shop, and I probably won't get it back until Monday, so I'll be at day 13 already. My state has vehicles be lemon qualified after 20 days in the shop due to defect/problem, regardless of how many times they tried to fix each.
Hey, and on the bright side, so far my 4 loaners have been an XC90 B6 (same one twice), an XC60 B6, and an XC40 B6 (I think) all with under 700 miles on them. None were plug ins. The XC90 T8 drives sooooo much better than any of the loaners
. There's zero comparison between the XC90 B6 and T8's acceleration, how they feel and sound at low speeds I wonder what they'll bring me this time, maybe a s90 to toy around in. I should start leaving notes to see if other XC90 T8 drivers are in the loaner for the same problem
