Not as of yet. However, I have had the “Poor Def quality, 1000 miles until speed limited to 55 MPH” message. Fortunately, for me it went away on its own after about 10 miles. Others haven’t been so lucky. I’m not sure at what mileage number but if you drive long enough with that message it reduces you to a max of 15mph. Other emissions systems faults also trigger that… known as limp mode. My tune eliminates limp mode.
It wasn’t a bad vehicle. Kind of a Chevy venture van with weird body lines. I used to have a theory(back when I cared) that certain types of personality disorders are drawn to different car models. Buick made a little SUV that was basically the same platform as that Aztec. I told my boss I couldn’t remember meeting anybody who bought one on purpose that I actually liked. Explained to him my personality disorder thing. All while knowing his girlfriend just bought one. Good times
I find that if you drive a rover v6 diesel over 65 mph the cat gets too hot to inject cow piss. It’s interesting that GM will limit the speed. I guess to cool down the cat?
I would worry about contaminated or poor quality fuel. On JLR’s little 4 cylinder diesel needing a high pressure pump and 4 injectors would total the car. Like more than 20 grand with labor
JLR displays a message that says no restarts in 300 miles and starts counting down.
The Canyon has 2 fuel filters that do a really good job as far as I can tell. I have heard of the high pressure pump failing and sending metal shards into the injectors which then stick open causing a hole in the piston that then comes apart and destroys the engine. Makes me miss the old Bosch L-Jetronic system that was extremely reliable and used on many different foreign made vehicles. My Triumphs used it. When I went to a self service yard I would pull parts from BMWs, Volkswagens, Fiats, and others I can’t recall. Datsun 280s used Nippondenso stuff but you could use them in place of the Bosch stuff in many cases. Seems it was so good the Japanese essentially copied it. On a related note, I had a an MGB short block on the work bench next to a Datsun 4 cylinder of the same displacement. It was incredible how similar they were. I believe they took the MGB block and improved it.
As I mentioned in an earlier comment a guy on TW posted his dealership offered tunes. As I also mentioned earlier they use the stock file so it will only show up as a ECU reset. Same as disconnecting the battery cable.
When I was in my 20’s I worked on all the GM diesels. Could reseal the Rosa-master pumps Olds ran in the 5.7. Then the bigger turbo diesels in 1 ton trucks. We called them percolators and marble grinders. People hated them. Then the common rail technology made them drive really nice. But NOx levels in the exhaust went thru the roof. NOx has been determined to be the most harmful to our health of all the exhaust gasses. So then someone figured out that injecting ammonia into the cat will reduce or eliminate it. So now the common rail diesel has 2 strikes against it. Cost of repairs and a system to haul cow piss for injection into the cat. No thanks
No it don’t work like that. Calibration files have ID#’s and get checked constantly. Another computer might even store a fault it don’t like the new shift pattern. You go on with your bad self Toyota guy.
I understand that at some point I posted something that triggered you. It's obvious you hold a grudge and are vindictive. That said what purpose does this serve?
Like I've said, I looked over and over and have found not one instance where warranty was denied due to a tune. That's not to imply it hasn't happened, but nobody has posted about in on the internet that I, nor anyone else, has found. I can show you post where tunes are shown to be EPA complaint. It is a very popular mod in the Toyota community. Having done it it's easy to see why.
My LRs will always outnumber any other make model I own. The GMC and or possible Toyota get the grunt work. The LRs and Triumphs have a much more fun and enjoyable life. They are treated like royalty. The others are commoners.
