2019 I finally bit the bullet and bought my first brand new car, thinking I would buy new, do epic maintenance, and keep forever. WRONG! My old 200k mile cars were at the shop less than this thing.
2018 Honda Pilot EX, 3.5L V6, AWD, automatic transmission, 30K miles. Original owner. All Honda recommended maintenance for "extreme driving conditions" done at recommended intervals except for the 30K mile that is due now. I haven't done it because I'm ready to get a different car if I can't figure this out. We have towed a 3K GVW camper a handful of times but have never had it at max weight. Max tow cap of Honda is 5K.
4 times now the vehicle has been having problems shifting between gears for only a few hours and then it miraculously heals itself when the shop drives it. No error codes, no dash lights. It will accelerate and I can feel it "disengaging" from one gear (like when you push down the clutch peddle on a manual) the RPM will rev from around 1K to 2.5K and then it will jerk hard into the next gear and the RPM will go back down to around 1K and accelerate fine until it shifts up or down again and does the same thing. This has only happened 4 times. The last 2 times there was also a slight smell of electrical smoke in the cabin. The first time it jerked/smoked there was a couple seconds of smoke coming from under the hood. When I opened hood the smoke had already dissipated. Second jerk/smoke only a slight smell of smoke.
As far as I can tell (I'm no mechanic) the jerking/revving happens through all the gears but a higher increase in RPM and slightly more delay between 1st/2nd and 2nd/3rd. It isn't nearly as bad of a surge and jerk when shifting up/down in the higher gears. It also happens when car is cold or warm and at different times though out the day. It might happen worse when A/C is on but I'm not 100% sure about that. It has done it when A/C has been on and off, but I think it might be worse when A/C is on. It hasn't yet done it (that I've noticed) when the heater is on but IDK if it's had a chance to since it's only happened 4 times.
I have brought the vehicle to 2 different shops and 5+ people have looked at it.
1st time (about 20K miles) brought to Honda dealer. Computer diagnostics didn't show codes. They could not reproduce with test drive.
2nd time (24K miles) Honda dealer didn't find anything. Having and working on VW's 20 years ago made me think this might be a major problem and I took it to the transmission repair shop that I used to bring VW transmissions to for rebuild (they don't just rebuild transmissions anymore, but same owner). They didn't find any PCM codes but found an interior light on and said it could be the transmission/computer having to re-learn if the battery got low, but that was all they could find.
3rd time (28,700miles). This was first time it smelled like smoke and surging Honda dealer said "tech recovered no codes at this time. No software updates available at this time. Not able to duplicate customers concern at this time." So then I drove back to the transmission shop and they said "Perform level 2 diagnostics-Attach scanner to read scan data and diagnostic trouble codes. Inspect Voltage references. Research technical data bases. No codes in PCM at this time. Cannot duplicate customer concerns at this time."
4th time (30K miles). Shifting hard and smelling faintly like electrical smoke. Drove strait toward transmission shop 3 miles away but SUV self healed and was shifting fine by the time I got there, so I just took it home.
Any ideas what could be wrong?
Should I get rid of this thing? This just isn't right...30K miles and so now out of bumper to bumper warranty.
Pilots have a long history of transmission problems. (of course Honda would never admit that).
Get rid of it.
Yah. I don't really have a good feeling about it. Got Pilot over Highlander cuz seats were more comfortable.
