Tow capacity within limits
MY wife and I are looking for a Jeep Wrangler Unlimited Sport Diesel Auto and I note that the 2007 and 2008 models have a very modest 170kg unbraked towing capacity, whereas the 2009 models onwards have a 750kg unbraked towing capacity. The braked towing capacity for all models is 2300kg. Towing is important for us as we have a large caravan (braked), but also two smaller (single and tandem) trailers. I understand from Jeep Customer Service that the towing capacity may be limited by vehicle compliance, but I don’t understand what the physical differences in the models may be to have such a difference. Do you know why this is please?
Jonno, email We checked with Chrysler and the information they provided was that all Limited models have the same unbraked towing capacity, 750kg. You might be confused with the towball rating, which is 170kg. COOLER IS FINE I received an Engel thermoelectric cooler (model TE 08) as a Father’s Day gift and was wondering if it would overload the alternator on a Kia Sorento if used for four or five hours at a time? Also, would it affect the warranty?
DonBonny, email We asked Kia and we were told: ‘‘ The Engel thermoelectric cooler model TE 08 draws 4 amps per hour, so if the engine is running there should be no issue with the cooler. There is no issue with the warranty on the amp. If the cooler is used for extensive periods without the engine running then the battery will be on a constant draining/ recharging cycle that could reduce the life of the battery.’’ RAVOVER-REVS I have experienced a similar problem with my 2007 Toyota RAV4 Cruiser L auto to that experienced by Colin Smith ( Carsguide, November 9). On numerous occasions the engine has revved to maximum revs. It is quite unnerving. Most times it has occurred in my driveway when parking. I have pulled up, taken my foot off the accelerator and on to the brake and then shifted to park and the car has gone flat out to full revs with my foot nowhere near the accelerator. It’s also happened twice when I have been overtaking and the car has seemed to shift into neutral when I have planted my foot to accelerate with no power for a split second, then roar to full revs which has caused me to abort my attempt to overtake. My mechanic could find no fault, but thought it could be a computer problem.

Toyota says it will investigate the issues reported by Colin Smith if our reader gives his consent, and we are keen to hear the outcome of any investigation that takes place. Your mechanic could be right when he suggests it may be a computer problem. LANCER CRAWLING At the first set of traffic lights I come to my 2010 Mitsubishi Lancer CVT goes into a dangerous crawl mode and barely moves. I have tried shifting to manual mode, but
