Crank but wont start, lost power while driving. I happen to be in a neighborhood street so I just parked to the side, but could potentially be dangerous if in a different situation.

When driving my 2004 xc90 it would just cut out completely and the steering and brake's would go all heavy this is a very dangerouse issue and it is definatly a safety issue and there should be a recall as the other poster said that it's water getting into the ECM and causing this problem. I will be reporting this to the relevant vehicle safety department. Also i have looked at other VOLVO FORUM'S and it seem's like quite a few people are experiancing the same problem. This should be a RECALL because it is dangerouse to drive a car with a potential ECM failure issue. If you have the same problem then please report to the relevant authority indicating this is a safety issue. I can't beleive that volvo have not initiated a RECALL on this very seriouse issue. Thank's

On several occasions the car would not start. When the key was turned nothing would happen. Car was towed 3 times. First time they stated it was the starter motor. Second time new battery. Third time it was the electronic control module that needed replacememt. A common problem as I under. I believe that all 3 times it was the ECM. Water leakage can get into the unit via a poorly designed rubber grommet (seal). Only the Volvo dealerhip can replace/programme the unit. Cost to replace $1250 (excluding towing and preliminary diagnosis etc.)not covered by Volvo. Whole repair was about $1500 in the end. On the plus side the mileage went up by almost 4 mpg. (by the way, if you are handy and your starter needs replacing its a very easy since its located at the upper front of the engine.)

My 2015 Volvo XC90 Inscription model has had a recurring problem of unreliable starting in cold temperatures. It is about to be towed on a flatbed to the local Volvo dealer to fix it again. The last time they claimed to have corrected it with re-programming, and replacing the battery.

We had two nights of -15 to -19 F here in central NH and the car would not start despite having a 15 amp charger on the provided battery positive and negative posts under the front hood. After leaving the 15 amp smart charger on it overnight, the following morning the readout states: "Battery Failure", though the battery is less than 9 months old. We bought a new battery and applied jumper cables to try and get the car started but the starter motor would not engage. We checked the voltage at 12.4 volts with the warm new battery connected in "parallel" with the two battery posts under the front hood. (They are intended for jumper cable use) The stock battery (9 months old since replaced by the dealer under warranty) reads 2.4 volts. I checked that no electrical devices were on when seeing the 2.4 volts. Perhaps there is a phantom electrical drain or the batteries Volvo uses are simply of inferior quality in the cold.

It is a very frustrating situation, that I have to turn to my 2014 P85D Tesla model S to go somewhere in the very cold temperatures, as electric cars as a general rule get reduced range when very cold.
