if they are so reliable, why did you need to have 17 of them?
Why not? I drive cars. And get cars that are joy to drive (which explains why my Toyota has lower mileage).
VW, Mercedes-Benz, BMW and Audi have turbo engines and they all have issues.
Turbos put lots of wear on a 4 cylinder engine. The stress that they put on an engine cause the engine to not last very long like a NA engine. Turbos are also not reliable and they don’t last long.
Do you know about engines!
All cars have issues (for example, turbos don’t have HEMI tick). It doesn’t matter what you get (my most problematic vehicle is Land Cruiser I have in Europe, second one is Sienna V6). I have business there with 20+ delivery vehicles that all run, and always did turbo engines. Some time ago those were all 1.9, 2.0 turbo diesel engines, now mostly 1.3-1.6ltr turbo gasoline engines that run natural gas. They all rack up ridiculous mileage. You do realize that 99% of taxi vehicles Europe are turbo?
So, AGAIN, what kind if issues they do have?
I have VW Tiguan for last 10yrs which was more reliable then Sienna V6 that has less mileage. Before that I had also one VW with same engine.
So, some wisdom would be nice so I know what problems to expect.
I know with Honda they require you to run the highest grade of future on their turbo powered vehicles. In all likelyhood you will be required to do this with the Highlander, costing you more at the pumps.
Bcs. they were riding the cheap gas train forever. Honda turbo engines are garbage. Huge fuel dilution issues, LSPI, etc. Therefore they have to now do whatever is necessary to remedy issues. Toyota is also behind so yeah, it might require.
VW, Mazda run on regular. Personally, I would never do it on regular, but people do it.
