I bought a 2013 Volvo C70 in July of 2018 and by August of 2019 I was replacing the engine. I take ownership for my oversight in not knowing to check the coolant tank regularly as this is my first car. It seems like negligence taking into account that my Volvo can tell me the amount of gas it has, the miles it can travel on the amount of gas I have, and indicates I am low on gas after the gauge has already entered into the red. My car can also tell me when I have low tire pressure so I know to refill them. Why isn't there a low coolant light on my car? arguably, the low coolant light and impending engine overheating and failure take precedence over running out of gas or getting a flat tire. August 23rd, 2019, my car overheated due to a lack of coolant. The lack of coolant was due to a crack in the coolant tank. My car never indicated to me that it was in distress until I was on the 10E to pick up my boyfriend from the airport and my car overheated. All the lights came on and the display read "overheating, pull over safely". I had no idea that was 2 minutes before I would warp my engine and my car completely died. There is construction on the 10E so there was no safe place for me to pull over. Everything just turned off, even my blinkers to notify the 18 wheeler behind me. The police were called and traffic was stopped as he pushed me off the road to the shoulder I was trying to get to before the failure. Maybe because I do not travel far from my home for work had my engine not overheated on those drives. Regardless, with all the technological advances on cars, a low coolant light should be mandatory. Especially because $5000 later (warranty company won't cover it), what good were my gas light and gauge?

Unit has intermittent engine/exhaust brake malfunction. This is causing the vehicle engine/ exhaust brake to disengage when on a decline at highway speeds. As result the vehicle picks up a great deal of speed and could cause the over use and eventual failure of the vehicle's air brake system. As well as the inability to control the vehicle (though application of the air brakes and/or steering) on a downgrade. There is no warning prior to engine/exhaust brake failure. This originally happened to me while traveling on East bound I-80 over donner pass summit heading towards truckee, ca. And has happened 3 more times since then. The local Volvo truck dealership can find nothing wrong with the vehicle.
