I recently had a rental from Sixt during my trip to San Diego and LAX. The experience was SEVERELY TRAUMATIC and a DISGRACE to your company. We picked up a Chevrolet SUV on 1/5. On 1/6, while driving up the Pacific Highway, we got a flat tire. We had a difficult time getting in contact with the representative (one hung up on us), and when we were finally able to have your faulty front right tire replaced, we were told that we would have to use the spare. The lovely individual who changed the tire to the spare was the only positive part of the entire Sixt experience (and he didn’t even work for Sixt!). It was likely a pinhole that split. We were told that the spare only could be driven 50 miles, while we were 58 miles from LAX, where we were supposed to trade out the dud vehicle. WHAT WOULD HAPPEN DURING THOSE 8 ADDITIONAL MILES IF THE SPARE DID NOT HOLD?! Additionally, we were told we could not exceed 50 mph for safety reasons on the California freeway. This was my first time driving in Southern California, and to have to ride in the right lane on a 6 lane freeway for 55 miles praying that the car would be able to get back to trade in with my elderly and sickly mother in the passenger seat was ONE OF THE MOST TRAUMATIC EXPERIENCES OF OUR LIVES, full of panic, stress, fear for our safety and lives. THERE ARE NO PLACES TO PULL OVER ON A FREEWAY IF THERE IS AN ISSUE! When we returned, the girl said the tear looked like it must have spread. We were given an “UPGRADE” to a Mercedes SUV when we finally arrived back. As we pulled in to return the car, the low air pressure light went on. Now, after returning the vehicle, I received a notification via email today from SIXT that your REPLACEMENT VEHICLE that was supposed to have been upgraded also had a FAULTY FRONT RIGHT TIRE. Frankly, your company is running a SCAM for customers. WE ONLY HAD EACH VEHICLE FOR 24 HOURS! HOW COULD THERE BE AN ISSUE WITH BOTH VEHICLES, FRONT RIGHT TIRE, WITHIN THAT TIME?! Are you buying faulty front-right tires and pawning this off on customers??? This is a SAFETY HAZARD!!! CUSTOMERS WHO RENT CARS DESERVE TO BE SAFE!!! Within 48 hours of our rental experience, BOTH of your vehicles that you have us had faulty front right tires. GIVING CUSTOMERS DEFECTIVE RENTAL CARS IS A DISGUSTING PRACTICE! This ruined our trip and caused severe trauma and distress to my elderly mother and me. We demand a full refund for this experience.
