Land Rover Defender Hybrid Cruise Control Failure Fix?

Hey there! I actually had a similar issue with my 2020 Land Rover Discovery Sport PHEV last winter. When my cruise control failed, it turned out to be a faulty cable connection to the radar sensor. The mechanics found corrosion on the connector pins, which was interrupting the signal. The fix wasn't too complex, they cleaned the connections, replaced the damaged cable, and recalibrated the sensor. It wasn't a major repair, but it needed proper diagnostic equipment to identify the exact problem. The system needed a full reset after the repair was done. Got it fixed at the dealership since they had the right diagnostic tools. Definitely recommend getting it checked soon, driving without cruise control is manageable, but it could indicate other potential sensor issues that might affect your safety systems. I'd suggest going to a certified Land Rover service center for this one. They'll have the specific equipment needed to properly diagnose and fix the issue. Best of luck!

Thanks for sharing that about your Discovery Sport! I had almost the exact same problem with my Defender last year. The sensor connections were causing trouble for me too, though mine was because of some debris buildup rather than corrosion. Would you mind sharing how much you ended up paying for the fix? Just curious if prices have changed much since then. Also, has everything been working smoothly since the repair, or have you noticed any other quirks with the cruise control?

Hey again! Great to hear back from you! Yeah, I just got my Discovery Sport back from the mechanic last week actually, they sorted out that cruise control issue I mentioned. The total bill came to 155.00 € for fixing that faulty cable connection to the sensor. And I'm happy to report everything's working perfectly now! The cruise control kicks in smoothly, just like when the car was new. No more unusual shutoffs or warning lights, it's such a relief. The mechanic mentioned they did a thorough cleaning of all the sensor connections while they were at it, which probably helped prevent any future issues. Haven't noticed any quirks or problems since the repair. I've done quite a bit of driving this past week, and the cruise control's been rock solid. It's amazing how something as small as a dodgy cable connection can cause such a headache, isn't it? Sounds like you got a pretty similar fix last year, hope your Defender's still running smoothly too! These things can be a bit finicky sometimes, but when they're working right, they're great cars. Let me know if you need any other info!

Thanks for the detailed follow-up! Yeah, my experience at the mechanic today was actually pretty similar to yours. The sensor needed a good cleaning and recalibration. They charged me about 175 for the whole job, which seems fair considering the work involved. It's such a relief to have it working properly again! Did a quick test drive and the cruise control's responding perfectly, no more unusual shutoffs or error messages. The mechanic also gave everything a thorough check while they were at it, which was reassuring. Funny how these high-tech features can be brought down by something as simple as a dirty sensor or loose connection, right? But at least it wasn't anything major like I initially feared. Really appreciate you sharing your experience, helped me feel more confident about getting it sorted. Thanks again for all your help! Time to enjoy some hassle-free driving.
